Complete Solar Knowledge Base for Los Cabos and Baja California Sur

Why Los Cabos Is One of the Best Regions for Solar Energy

Los Cabos and Baja California Sur receive strong sunlight throughout most of the year, making the region highly suitable for residential, commercial and off-grid solar energy systems.

Solar panels produce electricity whenever sunlight reaches the solar cells. The stronger and more consistent the sunlight, the greater the opportunity for dependable annual energy production.

Baja California Sur has long periods of clear weather, limited winter cloud cover and strong solar exposure. These conditions create an excellent environment for solar panels, but they also create important design challenges.

Extreme heat can reduce the instantaneous output of solar panels. Salt air can corrode low-quality hardware. Dust can collect on the surface of panels. Hurricanes can expose solar structures to powerful winds. Inverters and batteries must be protected from heat, water and flooding.

A professional solar installation must take advantage of the strong sunlight while also addressing these local environmental conditions.

☀

Strong Sunlight

High solar exposure gives homes and businesses the opportunity to generate substantial electricity from a properly sized array.

🌡

High Temperatures

Equipment must be selected and installed with ventilation, temperature derating and heat management in mind.

🌊

Salt Air

Coastal properties require careful hardware selection, conduit protection and ongoing inspection for corrosion.

🌀

Hurricane Exposure

Structural mounting and electrical equipment placement must consider wind, rain, debris and extended utility outages.

How a Solar Energy System Works

A solar system converts sunlight into electricity that can be used by a home, business, battery system or utility-connected electrical service.

Step 1: Solar Panels Produce DC Electricity

Solar panels contain photovoltaic cells. When sunlight reaches the cells, they produce direct-current electricity, commonly called DC power.

The amount of electricity produced depends on the panel wattage, sunlight intensity, temperature, panel orientation, shading, dirt, wiring losses and system design.

Step 2: The Inverter Converts the Electricity

Most homes and businesses use alternating-current electricity, commonly called AC power. The inverter converts the DC electricity from the solar panels into AC electricity that can be used by normal appliances and electrical equipment.

The inverter also controls how electricity moves through the system. A grid-tied inverter works with the utility. A hybrid inverter can manage solar panels, batteries, CFE electricity and, in some systems, a generator.

Step 3: Solar Supplies Active Loads

When the property is using electricity during sunny hours, solar production can supply part or all of that immediate demand.

For example, if a property is using 6 kilowatts and the solar array is producing 5 kilowatts, the system may provide 5 kilowatts from solar while the remaining 1 kilowatt comes from CFE or another available source.

Step 4: Extra Solar Can Charge Batteries

In a hybrid system, solar electricity that is not being used immediately can charge the battery bank. Stored energy can then be used at night, during cloudy periods or during a utility outage.

Step 5: The System Uses CFE or Generator Power When Needed

When solar production is insufficient and the battery reaches a programmed reserve level, the system may use CFE power. In an off-grid system, a compatible generator may charge the batteries or support large loads.

Simple explanation: Solar panels generate electricity. The inverter controls and converts that electricity. Batteries store energy. CFE or a generator provides additional power when solar and batteries are not enough.

Understanding Solar Production

A solar panel’s nameplate wattage is not the same as the number of kilowatt-hours it will produce every day.

Solar-panel wattage describes the panel’s rated power under standardized laboratory conditions. Actual production changes throughout the day. Output is low shortly after sunrise, increases toward midday and falls again in the afternoon.

Temperature, orientation, shading, dust, inverter losses and wiring losses also reduce actual production compared with the theoretical maximum.

Power Versus Energy

Power is measured in watts or kilowatts. Energy is measured in watt-hours or kilowatt-hours.

A 10-kilowatt solar array does not produce 10 kilowatt-hours every day. It may produce several times that amount over the course of a sunny day, depending on site conditions.

Example: Eight JA Solar 615-Watt Panels

Eight 615-watt panels create a solar array with a rated capacity of:

8 panels × 615 watts = 4,920 watts
Total array size = 4.92 kW DC

That does not mean the array will produce 4.92 kilowatt-hours per day. Its daily energy production will depend on the number of effective solar hours and the system’s real operating conditions.

Example: Sixteen JA Solar 615-Watt Panels

16 panels × 615 watts = 9,840 watts
Total array size = 9.84 kW DC

Example: Twenty-Four JA Solar 615-Watt Panels

24 panels × 615 watts = 14,760 watts
Total array size = 14.76 kW DC

Example: Thirty-Six JA Solar 615-Watt Panels

36 panels × 615 watts = 22,140 watts
Total array size = 22.14 kW DC

A 22.14-kilowatt system may be appropriate for a large home, restaurant, hotel, commercial kitchen or other high-consumption property, but final system sizing must be based on documented energy usage and site conditions.

What Are Peak Sun Hours?

Peak sun hours are a simplified way to describe the amount of usable solar energy available during a day. One peak sun hour represents an average solar intensity equivalent to 1,000 watts per square meter for one hour.

A location may receive sunlight for 10 or 12 hours, but that does not mean it receives 10 or 12 peak sun hours. Morning and afternoon sunlight is weaker than midday sunlight.

Solar designers use expected peak sun hours to estimate annual energy production. These estimates should be adjusted for:

Panel temperature
Inverter efficiency
Wiring losses
Dust and salt residue
Panel orientation and tilt
Seasonal changes
Shading
Equipment availability and curtailment

Do not use peak sun hours as a guarantee. They are a planning tool. Actual daily and monthly production will vary.

How Heat Affects Solar Panels, Inverters and Batteries

Strong sunlight is good for solar production, but high equipment temperatures can reduce output and shorten equipment life.

Solar Panel Temperature

Solar panels are rated under laboratory conditions. In the real world, panel temperatures can rise far above the surrounding air temperature.

As solar cells become hotter, their voltage typically decreases. This means a hot panel may produce less power than the same panel would under cooler conditions with identical sunlight.

Adequate airflow below the panels can help reduce excessive heat. Panels mounted directly against a surface with no ventilation may run hotter than panels with proper clearance.

Inverter Temperature

Inverters generate heat while operating. Many inverters reduce their maximum output when internal temperatures become too high. This is often called thermal derating.

Inverters should not be installed in direct afternoon sun unless the equipment is specifically designed and located for that exposure. Shade, ventilation and manufacturer clearances are important.

Battery Temperature

Lithium batteries generally perform best within the temperature range specified by the manufacturer. Extreme heat can shorten battery life.

Batteries should not be installed in sealed, unventilated metal boxes exposed to full sun unless the enclosure and cooling design are engineered for that environment.

Recommended Heat-Management Practices

Install inverters in shaded, ventilated locations
Maintain manufacturer-required clearance
Keep batteries away from direct rain and extreme afternoon sun
Allow airflow beneath solar panels
Do not block inverter cooling fans or vents
Inspect equipment for excessive heat warnings
Monitor system output during the hottest months

Solar Installation Near the Ocean: Salt Air and Corrosion

Coastal properties in Cabo San Lucas, San José del Cabo, the East Cape, Todos Santos and other parts of Baja California Sur can experience significant salt exposure.

Salt carried through the air can collect on metal surfaces, electrical enclosures, mounting hardware and solar panels. Over time, this can contribute to corrosion and reduced performance.

Areas Most Vulnerable to Corrosion

Panel clamps and mounting bolts
Roof attachments
Exposed steel structures
Electrical cabinets
Conduit fittings
Grounding connections
Battery racks
Outdoor disconnects

Corrosion-Reduction Practices

Use corrosion-resistant hardware where appropriate
Avoid mixing incompatible metals
Protect exposed steel with suitable coatings
Use weather-rated electrical enclosures
Seal conduit entries correctly
Inspect coastal systems regularly
Clean salt deposits when necessary

No outdoor installation is completely protected from the coastal environment. Regular inspection is part of responsible long-term maintenance.

Dust, Dirt and Solar Panel Cleaning

Dust and salt residue can reduce solar production by blocking sunlight from reaching the solar cells.

Baja California Sur has dry desert conditions, wind, unpaved roads, construction activity and coastal salt. These conditions can cause panels to become dirty faster than systems located in regions with frequent rainfall.

How Often Should Solar Panels Be Cleaned?

There is no universal cleaning schedule. The correct frequency depends on:

Distance from dirt roads
Distance from the ocean
Panel tilt
Local rainfall
Bird activity
Nearby construction
Measured production loss

Some properties may need cleaning several times per year. Others may require less frequent service.

Safe Cleaning Practices

Do not walk directly on solar panels
Avoid cleaning extremely hot panels with very cold water
Use non-abrasive tools
Avoid harsh chemicals unless approved by the manufacturer
Use fall protection when working on roofs
Do not touch damaged connectors or wiring

Roof safety matters. Cleaning solar panels is not worth a fall. Use trained professionals when the array cannot be accessed safely.

How Shading Affects Solar Production

Solar panels need direct sunlight for maximum output. Shade from trees, walls, water tanks, roof structures, antennas and nearby buildings can reduce production.

The effect of shade depends on the system design. Traditional string inverters connect multiple panels together. If one panel is shaded, production from the string may be affected.

Module-level electronics, such as microinverters or optimizers, can help reduce the effect of uneven shading, but they do not create sunlight. A shaded panel will still produce less energy than an unshaded panel.

Common Shade Sources in Los Cabos

Palm trees
Parapet walls
Water tanks
Roof-mounted air-conditioning equipment
Satellite dishes
Neighboring buildings
Mountain or hillside terrain
Future construction

Shade should be evaluated before the final panel layout is approved. It is usually better to install fewer panels in strong sunlight than more panels in poor locations.

Solar Panel Direction, Tilt and Roof Layout

Panel orientation affects when and how much electricity the system produces.

South-facing arrays often produce strong annual results in the Northern Hemisphere, but east- and west-facing arrays can also provide valuable energy.

An east-facing array produces more electricity earlier in the day. A west-facing array produces more electricity later in the afternoon. This may be useful for homes or businesses with heavy afternoon cooling demand.

Flat roofs often provide flexibility, but panel tilt and row spacing must be planned carefully to avoid one row shading another.

Layout Factors

Roof direction
Roof slope
Parapet-wall shading
Access pathways
Fire and service clearances where applicable
Hurricane wind exposure
Drainage
Future roof maintenance

Grid-Tied, Hybrid and Off-Grid Solar Explained

These three system types use solar panels, but they operate differently. Choosing the correct system depends on the customer’s goals and the reliability of the CFE grid.

System type	Main purpose	Battery required?	Works during outage?
Grid-tied solar	Reduce CFE electricity purchases	Usually no	Normally no
Hybrid solar	Reduce bills and provide battery backup	Usually yes	Yes, for designed backup loads
Off-grid solar	Operate without utility electricity	Yes	The system is always independent of CFE

Grid-Tied Solar

Grid-tied solar is usually the simplest option for customers who have dependable CFE service and want to reduce electricity purchases.

Standard grid-tied systems shut down during a utility outage to prevent power from being sent onto utility lines while repairs are being performed.

Hybrid Solar

Hybrid systems combine solar panels, batteries and CFE electricity. They can continue operating selected circuits when the grid is unavailable.

The amount of backup depends on the inverter capacity, battery size and electrical loads connected to the backup output.

Off-Grid Solar

Off-grid systems are designed for properties that do not rely on CFE. They require enough solar, battery capacity and backup generation to support the property through different weather conditions.

How Solar Batteries Work

Solar batteries store electrical energy for use when solar production is not immediately available.

Batteries can be charged from solar panels, CFE electricity or a compatible generator, depending on the inverter and system settings.

Battery Capacity

Battery capacity is measured in kilowatt-hours. A 5.12-kilowatt-hour battery can theoretically store 5.12 kilowatt-hours of energy, but the full nameplate amount may not be available for normal use.

Reserve settings, inverter losses, battery-protection limits and manufacturer requirements reduce usable energy.

Battery Power

Energy capacity and power output are different. A battery may contain enough energy to operate a refrigerator for many hours but still be unable to support a very large air conditioner without adequate inverter and battery discharge capacity.

Battery Runtime

Runtime depends on how much power the property is using.

Average load	Approximate theoretical runtime from 5 kWh	Real-world note
250 watts	Approximately 20 hours	Actual runtime will be lower after losses and reserve settings
500 watts	Approximately 10 hours	Suitable for selected essential loads
1,000 watts	Approximately 5 hours	Runtime falls quickly as load increases
2,500 watts	Approximately 2 hours	High-power loads may also exceed discharge limits

These are simplified examples, not performance guarantees. Actual runtime depends on battery condition, temperature, inverter efficiency, reserve settings and changing electrical loads.

Why Lithium Batteries Are Popular for Solar Backup

Modern lithium batteries are commonly used because they can provide strong cycle life, high efficiency, modular expansion and less maintenance than many traditional lead-acid battery systems.

Common Advantages

High charging and discharging efficiency
Greater usable capacity than many lead-acid systems
Long cycle life when operated correctly
Modular expansion
Integrated battery-management systems
Less routine maintenance
Compact installation compared with large lead-acid banks

Important Battery Limitations

Extreme heat can shorten battery life
Incompatible batteries and inverters may not communicate correctly
Battery capacity does not equal unlimited inverter power
Every battery has charging and discharge limits
Warranty coverage depends on operating conditions
Expansion may require matching models and firmware

How a Hybrid Solar System Operates During the Day and Night

Morning

Solar production begins after sunrise. The system may use available solar to supply active loads and begin charging the batteries.

Midday

Solar production is usually strongest near midday. The array may supply property loads, charge batteries and, where permitted and configured, interact with the utility connection.

Afternoon

Solar output begins to decline. If air-conditioning demand remains high, the system may use solar, battery energy and CFE electricity together.

Evening

After sunset, batteries may supply the property until they reach a programmed reserve level.

Night

Depending on the system settings, CFE may supply the loads while the battery remains reserved for outages, or the battery may continue supplying power.

Utility Outage

The hybrid inverter disconnects the backup system from the utility and supplies the designed backup circuits from solar and batteries.

The transition may be extremely fast, but exact behavior depends on the equipment and system design.

Choosing Which Loads Receive Battery Backup

The smartest battery system is not always the system that attempts to power everything.

Separating essential loads can provide much longer battery runtime. A refrigerator, lights, internet and security may require a small fraction of the energy used by several air conditioners and pool pumps.

Common Essential Loads

Refrigerator
Freezer
Internet and Starlink
Security system
Selected lighting
Television
Phone charging
Medical equipment
Selected outlets

Common High-Energy Loads

Large air conditioners
Electric water heaters
Electric ovens
Pool heaters
Large well pumps
Commercial kitchen appliances
EV chargers
Electric clothes dryers

High-energy loads can still be included, but the inverter and battery system must be sized accordingly.

Can Solar and Batteries Run Air Conditioning?

Yes, but air conditioning is one of the most important loads to evaluate accurately.

Air conditioners vary widely in capacity and efficiency. A modern variable-speed mini-split may use far less energy than an older fixed-speed unit.

The energy used also depends on outdoor temperature, insulation, room size, thermostat setting, occupancy and how frequently the compressor runs.

What Must Be Checked?

Air-conditioner voltage
Rated current
Starting current
Average running power
Daily operating hours
Number of units operating together
Desired nighttime runtime
Other simultaneous loads

Solar can often support air conditioning effectively during the day. Running multiple units overnight requires substantial battery storage.

Solar for Pool Pumps, Water Pumps and Motors

Pool pumps and water pumps can be excellent solar loads because they can often be scheduled to operate during sunny hours.

Running pumps during peak solar production reduces the need to store energy in batteries.

Motor Starting Current

Many motors require a brief surge of power when starting. The inverter must be capable of supporting that surge.

Variable-speed pumps often reduce energy consumption and starting stress. Replacing an inefficient pump may lower the required solar and battery size.

Recommended Strategy

Operate pool pumps during the day
Use timers or inverter controls
Consider variable-speed pumps
Avoid unnecessary overnight pumping
Measure large pump loads before final design

Why Battery Backup Matters During Hurricane Season

Hurricanes can damage utility infrastructure and cause outages that last from several hours to several days.

A hybrid solar and battery system can provide critical electricity when the CFE grid is unavailable. Solar panels can recharge batteries during daylight, reducing generator fuel consumption.

Critical Hurricane Loads

Refrigeration
Freezers
Internet and communications
Security cameras
Emergency lighting
Medical devices
Water pumping
Selected air conditioning

Before the Storm

Charge batteries to full capacity
Confirm monitoring is working
Test backup circuits
Test the generator
Reduce unnecessary loads
Secure exterior objects
Keep system manuals accessible

After the Storm

Do not touch damaged wiring
Do not energize flooded equipment
Inspect the array from a safe location
Check the monitoring system for faults
Photograph visible damage
Request a professional inspection when necessary

Common Solar Myths in Los Cabos

Myth 1: Solar Panels Produce Their Full Rating All Day

False. Output changes with sunlight, temperature, shade and time of day.

Myth 2: Solar Automatically Works During an Outage

False. Standard grid-tied solar normally shuts down. Backup requires compatible equipment and batteries.

Myth 3: One Battery Can Run an Entire Large Home All Night

Usually false. Runtime depends on the battery size and the loads. Air conditioning can use battery energy very quickly.

Myth 4: The Cheapest Solar Proposal Is the Best Deal

False. A cheap system may be undersized, poorly installed or unsupported. Compare the complete scope, not just the total price.

Myth 5: More Panels Always Means a Better System

False. Panels installed in shade, on weak structures or beyond the inverter’s design limits may create poor results.

Myth 6: Batteries Eliminate the Need to Manage Energy

False. Energy management becomes even more important during long outages.

How to Choose the Right Solar System

The right system begins with the right questions.

How much electricity does the property use?
Review at least one CFE bill and preferably twelve months of usage.
Which loads must operate during an outage?
Separate essential loads from high-energy optional loads.
How long should battery backup last?
Several hours of backup requires less storage than overnight or multi-day operation.
Is CFE service reliable?
Reliable CFE service may support a grid-tied or smaller hybrid system. Unreliable service may justify greater battery capacity.
Is a generator available?
A compatible generator can reduce the battery capacity required for rare extended outages.
Will the property expand?
Plan for additional rooms, air conditioners, pumps, EV charging or commercial equipment.
What is the budget?
The project may be divided into phases while preserving the final design.

Residential Solar Systems in Los Cabos

Residential solar systems can reduce CFE electricity purchases, provide battery backup during outages and give homeowners greater control over the energy used by their property.

Homes in Los Cabos vary dramatically. A small casita with one mini-split air conditioner may use a fraction of the electricity consumed by a luxury villa with multiple air conditioners, pool pumps, guest bedrooms, electric appliances, outdoor entertainment areas and rental units.

That is why residential solar should never be sized only by counting bedrooms or looking at the roof. A correct design begins with actual energy consumption, major electrical loads, property-use patterns and the homeowner’s backup priorities.

Some customers want the lowest practical starting cost. Others want to reduce nearly all of their annual CFE consumption. Some want only essential backup, while others want enough inverter and battery capacity to support air conditioning and most of the home during an outage.

Residential solar should be designed around the homeowner’s real goals. Bill reduction, battery backup, off-grid operation and whole-home resilience are different objectives and may require different equipment.

How Cabo Solar Experts Evaluates a Home

Before recommending panels, batteries or an inverter, Cabo Solar Experts evaluates how the home currently uses electricity and how the homeowner expects to use it in the future.

1. Review the CFE Bill

The CFE bill shows how many kilowatt-hours the property consumed during the billing period. Whenever possible, twelve months of bills should be reviewed because air-conditioning use can rise sharply during the hottest months.

2. Identify Major Electrical Loads

Large loads determine inverter capacity, solar-array size and battery requirements. These may include:

Mini-split air conditioners
Central air-conditioning systems
Pool pumps
Well pumps and pressure pumps
Refrigerators and freezers
Electric ovens and cooktops
Electric water heaters
Laundry equipment
Guest casitas
Electric vehicle chargers

3. Define Backup Priorities

A homeowner may want to back up only the refrigerator, internet, lighting and security system. Another homeowner may want to operate several air conditioners, pool equipment and the entire kitchen.

Those two homes may require very different battery banks even if their solar arrays are similar in size.

4. Inspect the Roof or Installation Area

Panel placement depends on available roof space, orientation, shading, roof material, structural conditions, drainage and wind exposure.

When roof space is limited, solar panels may also be installed on a ground-mounted structure, carport, patio cover or another properly engineered structure.

5. Inspect the Electrical Service

The main electrical panel, service voltage, breaker capacity, grounding, utility connection and backup-load arrangement must be evaluated before the final design is approved.

6. Plan for Future Growth

The homeowner may later add air conditioning, a pool, an electric vehicle, another casita or additional battery storage. Planning for these future loads can prevent expensive equipment replacement.

Solar Systems for Different Types of Homes

The property type influences energy consumption, backup requirements, system layout and the best financial strategy.

Small Homes and Casitas

Small homes may need solar for refrigeration, lighting, internet, one efficient mini-split and normal household appliances.

Full-Time Family Homes

Full-time homes often have higher daily consumption because of laundry, cooking, water systems and air conditioning.

Luxury Villas

Luxury properties may include multiple air conditioners, pools, outdoor kitchens, entertainment systems and guest areas.

Vacation Homes

Vacation properties may have irregular occupancy but require dependable refrigeration, security and remote monitoring.

Vacation Rentals

Rental properties must support guest comfort while controlling electrical expenses and reducing outage complaints.

Condominiums

Condominiums may have limited roof rights, shared electrical systems and association rules that require additional planning.

Solar for Small Homes and Casitas

Small homes can benefit from a modest solar and battery system when electrical consumption is controlled carefully.

A typical essential-backup system may support:

One refrigerator
Internet or Starlink
Selected lighting
Television
Phone and computer charging
Small kitchen appliances
One efficient mini-split, depending on design

Customers should not assume that a small system will operate every appliance without limits. Electric ovens, water heaters, large pumps and several air conditioners can exceed the available inverter or battery capacity.

The best strategy for a smaller system is usually to prioritize essential loads and operate high-energy equipment during sunny hours.

Solar for Luxury Homes and Villas

Large homes in Los Cabos often have substantial electrical demand and require a carefully engineered combination of solar production, inverter output and battery capacity.

Luxury homes may include:

Multiple mini-split or central air-conditioning systems
Swimming pools and spas
Electric pool heaters or heat pumps
Outdoor kitchens
Large refrigeration systems
Water pumps and filtration systems
Entertainment systems
Guest houses
Elevators
Electric vehicle charging

These homes may require more than one inverter or a larger-capacity inverter platform. Battery storage may need to be divided into several modules to provide the required energy and discharge capacity.

Load management can still be useful. Even a large battery bank will last longer if unnecessary air conditioners, pool heaters and other heavy loads are turned off during an extended outage.

Solar for Condominiums and HOA Properties

Condominium solar projects may involve privately owned roof areas, common roofs, shared electrical meters, HOA approval and architectural requirements.

Before designing a condominium system, the customer should confirm:

Who owns or controls the roof area
Whether the HOA permits solar installations
Where the utility meter is located
Whether the electrical service is private or shared
Where the inverter and batteries may be installed
How conduit can be routed
Whether exterior equipment must be concealed

Some condominiums are better suited for individual unit systems, while others may benefit from a common-area solar project.

Solar for Vacation Rentals and Airbnb Properties

Vacation rentals can have unpredictable energy consumption because guests may operate air conditioners and appliances differently from the property owner.

Solar can reduce operating expenses, while battery backup can help protect the guest experience during power outages.

Common Vacation-Rental Priorities

Keep internet working
Maintain refrigeration
Support selected air conditioners
Keep security cameras operating
Maintain water pressure
Reduce CFE costs during high occupancy
Monitor the system remotely

Owners should consider smart thermostats, energy-monitoring devices and clear guest instructions. Solar alone cannot prevent guests from wasting electricity.

A rental property may require a larger system than an owner-occupied home of the same size because the owner has less control over daily energy use.

Essential-Load Battery Backup

Essential-load backup focuses battery energy on the circuits that matter most during an outage.

Instead of connecting the entire property to the backup output, selected circuits are moved to a critical-load panel or otherwise controlled by the hybrid system.

Typical Essential Loads

Refrigerator
Freezer
Internet modem or Starlink
Security system
Selected lights
Television
Phone charging
Medical devices
Selected water pump
One efficient mini-split when properly sized

Why Essential Backup Can Be Smarter

Battery runtime is determined by energy consumption. Removing high-power loads can extend backup time significantly.

A system designed for essential circuits may provide greater practical resilience than a more expensive whole-home system that allows every large appliance to drain the battery rapidly.

Whole-Home Battery Backup

Whole-home backup means the hybrid system is capable of supplying most or all of the home’s electrical distribution during an outage.

It does not mean that every load can be operated without limits.

The homeowner may still need to avoid operating several large appliances at the same time.

Whole-Home Backup Design Must Consider

Maximum inverter output
Maximum battery discharge power
Total usable battery capacity
Motor-starting current
Air-conditioning demand
Water-pump demand
Electric cooking equipment
Pool equipment
Desired outage duration

Whole-home backup is not unlimited energy. The customer must understand both the power limit and the stored-energy limit of the proposed system.

Residential Solar and Air Conditioning

Air conditioning is often the largest electrical load in a Los Cabos home.

Solar panels can support air conditioning effectively during the day, especially when the cooling demand aligns with peak sunlight.

Nighttime air conditioning requires battery storage. The required battery capacity depends on the air-conditioner efficiency, room temperature, insulation, operating hours and number of units.

Mini-Split Air Conditioners

Modern inverter-driven mini-splits can be more efficient than older fixed-speed systems. They adjust compressor speed rather than repeatedly turning completely on and off.

An efficient mini-split may be a practical backup load when the system is designed correctly.

Central Air Conditioning

Large central systems may have high starting current and substantial continuous demand. They require careful inverter and battery sizing.

Ways to Reduce Cooling Energy

Use efficient variable-speed equipment
Improve insulation
Seal air leaks
Use reflective roofing where appropriate
Shade windows
Set reasonable thermostat temperatures
Cool occupied areas instead of the entire property
Clean air filters regularly

Solar for Pool Pumps and Pool Equipment

Pool equipment can represent a major percentage of a home’s electrical consumption.

Pool pumps are excellent daytime solar loads because they can usually be scheduled to operate while the solar array is producing electricity.

Variable-Speed Pool Pumps

Variable-speed pumps can use substantially less electricity than older single-speed pumps when programmed correctly.

Reducing pump energy may be more cost-effective than installing additional panels to support an inefficient pump.

Pool Heating

Electric resistance pool heaters can consume enormous amounts of electricity. Heat-pump pool heaters are generally more efficient but still require significant energy.

Solar-thermal pool heating may also be considered where appropriate.

Recommended Pool Strategy

Operate circulation during sunny hours
Use variable-speed pumps
Use a pool cover to reduce heat loss
Avoid unnecessary overnight pumping
Separate pool-heating calculations from normal household loads

Solar for Water Pumps and Pressure Systems

Many homes in Baja use cistern pumps, pressure pumps, well pumps or water transfer pumps.

Motor loads require special attention because they may draw several times their normal running current while starting.

Information Needed for Pump Design

Pump voltage
Horsepower
Rated running current
Starting current
Daily operating time
Whether several pumps operate together
Whether the pump must run during outages

Pumps can often be scheduled during solar-production hours, reducing battery use.

Solar and Electric Kitchen Appliances

Electric cooking equipment can create high short-term demand.

Ovens, electric cooktops, microwaves, coffee machines, dishwashers and refrigerators may operate at the same time.

A residential solar and battery design should consider both the total energy consumed and the highest simultaneous power demand.

High-Power Kitchen Loads

Electric oven
Induction cooktop
Electric water heater
Dishwasher heating element
Microwave oven
Large coffee machines
Garbage disposal

Homes using propane for cooking and water heating may require less solar and battery capacity than fully electric homes.

Solar for Laundry Equipment

Washing machines generally use less electricity than electric clothes dryers.

Electric dryers can have very high power demand. Gas dryers usually use less electricity but require gas service.

Laundry equipment can be scheduled during sunny hours to reduce battery use.

Energy-Saving Laundry Practices

Wash clothes during peak solar hours
Use cold water when practical
Air-dry clothing when possible
Avoid using the dryer during a utility outage
Use energy-efficient appliances

Solar and Electric Vehicle Charging

An electric vehicle can become one of the largest electrical loads at a residential property.

EV charging should be included in the solar design even if the homeowner does not yet own an electric vehicle.

Level 1 Charging

Level 1 charging uses a standard low-power outlet. It charges slowly but may be adequate for drivers with limited daily mileage.

Level 2 Charging

Level 2 charging uses a dedicated higher-power circuit and charges the vehicle faster.

A Level 2 charger may require several kilowatts for multiple hours, significantly increasing daily energy consumption.

Best Solar-Charging Strategy

Charge during sunny hours when possible
Use adjustable charging current
Avoid draining home batteries unnecessarily
Coordinate charger size with the electrical service
Include future EV demand in the solar-array design

How to Size Residential Battery Storage

Battery sizing begins by identifying the loads, their average power and the number of hours they must operate.

Simplified Example

Assume essential loads average 700 watts during an outage.

If the homeowner wants approximately eight hours of backup:

0.7 kW × 8 hours = 5.6 kWh of energy

The installed battery capacity would need to be greater than 5.6 kWh because of inverter losses, battery reserve settings and changing loads.

Air-Conditioning Example

If one mini-split averages 1,000 watts and operates for eight hours:

1.0 kW × 8 hours = 8 kWh of energy

That estimate is for the air conditioner alone. Refrigeration, lights, internet and other loads must be added.

Why Nameplate Capacity Is Not Fully Usable

Battery reserve may be maintained for protection
Inverter conversion causes losses
Battery-management systems may limit discharge
Temperature can affect available capacity
Loads change throughout the night

How to Estimate Residential Solar-Array Size

Solar-array size should be based on energy consumption, not merely roof space.

The first step is to estimate average daily kilowatt-hour consumption.

Example: 1,800 kWh Every 60 Days

1,800 kWh ÷ 60 days = 30 kWh per day

If the site produces an estimated average of five useful kilowatt-hours per installed kilowatt each day before final losses:

30 kWh ÷ 5 = Approximately 6 kW of solar

The final system may need to be larger after accounting for heat, inverter losses, shading, orientation, seasonal changes and the desired annual offset.

Panels Required Using 615-Watt Modules

6,000 watts ÷ 615 watts = Approximately 9.76 panels

In practice, the design might use 10, 12 or another practical number of panels based on inverter input limits and roof layout.

This is only a simplified example. Final system sizing requires actual consumption history and a property evaluation.

Understanding Residential Solar Cost Per Watt

Cost per watt can help customers compare solar proposals, but only when the systems being compared include similar equipment and services.

The basic calculation is:

Total installed project price ÷ solar-array watts = installed price per watt

Package 1 Example

Eight 615-watt panels create a 4,920-watt array.

$9,995 ÷ 4,920 watts = approximately $2.03 per watt

Package 2 Example

Sixteen 615-watt panels create a 9,840-watt array.

$19,995 ÷ 9,840 watts = approximately $2.03 per watt

Package 3 Example

Twenty-four 615-watt panels create a 14,760-watt array.

$29,995 ÷ 14,760 watts = approximately $2.03 per watt

These calculations use the total package price, including battery storage and other equipment. That makes them fundamentally different from solar-only cost-per-watt figures.

Many United States residential solar-plus-storage systems can cost substantially more per installed watt, depending on battery capacity, equipment, location, permitting, labor and financing.

Cost per watt does not measure battery capacity. A proposal with three batteries cannot be compared directly with a solar-only proposal using cost per watt alone.

Residential Solar Return on Investment

Solar return on investment depends on current electricity expenses, system cost, solar production, future CFE rates, maintenance and changes in household consumption.

Example: 8,000 MXN CFE Bill Every 60 Days

8,000 MXN × 6 billing periods = 48,000 MXN per year

If a solar system reduces annual CFE electricity purchases by 80%, the estimated gross annual savings could be:

48,000 MXN × 80% = 38,400 MXN per year

Actual savings may be lower or higher depending on energy use and CFE billing rules.

Example: 15,000 MXN CFE Bill Every 60 Days

15,000 MXN × 6 = 90,000 MXN per year

An 80% reduction would represent estimated gross annual savings of:

90,000 MXN × 80% = 72,000 MXN per year

What Improves Solar ROI?

High current CFE expenses
Strong daytime consumption
Minimal shading
Efficient appliances
Proper system sizing
Using solar energy directly
Avoiding unnecessary battery oversizing
Maintaining the system

What Can Reduce ROI?

Heavy shading
Oversized batteries that are rarely used
Increased consumption after installation
Poor equipment placement
High financing charges
Unnecessary structural work
Inadequate maintenance

How Homeowners Can Maximize Solar Savings

The way a homeowner uses electricity can affect the value received from the system.

Use Energy During Solar-Production Hours

Schedule pool pumps, laundry, dishwashing and other flexible loads during sunny hours.

Improve Efficiency Before Oversizing Solar

Replacing inefficient air conditioners, pumps and appliances may reduce the required solar and battery capacity.

Control Vacation-Rental Consumption

Smart thermostats, locked temperature limits and occupancy controls can reduce guest energy waste.

Monitor Production and Consumption

Monitoring helps identify unexpected increases in usage, equipment faults and underperforming solar production.

Maintain the Solar Array

Excessive dust, salt and bird residue can reduce production. Cleaning should be performed when needed and when it can be completed safely.

Building a Residential Solar System in Phases

A homeowner does not always need to purchase the final system all at once.

A phased system can begin with an inverter, battery and smaller solar array. Additional panels and batteries can be added later when the infrastructure is designed correctly.

Example Phased Plan

Phase	Possible equipment	Primary objective
Phase 1	Hybrid inverter, one battery and initial solar panels	Begin saving and establish backup capability
Phase 2	Additional solar panels and battery storage	Increase energy production and nighttime runtime
Phase 3	Final panels, batteries or second inverter	Reach the final energy-independence target

The first phase should be planned around the final system. Otherwise, the customer may later need to replace wiring, equipment or racking.

Residential Solar Maintenance

Solar systems require less routine maintenance than generators, but they should not be ignored.

Homeowner Monitoring Checklist

Review solar production regularly
Check for inverter fault messages
Confirm batteries are charging
Confirm backup circuits operate
Look for unexpected changes in CFE consumption
Inspect for visible panel damage after storms

Physical Inspection Checklist

Loose or damaged conduit
Corroded hardware
Bird nests or animal damage
Water intrusion
Blocked inverter ventilation
Excessive dust or salt buildup
Damaged labels

Electrical cabinets should not be opened by unqualified persons.

Continue to Part 4: Commercial Solar Systems

Part 4 will cover restaurants, hotels, resorts, offices, warehouses, retail properties, farms, HOAs, schools, commercial three-phase systems, phased installations, business continuity, commercial ROI and energy-cost reduction.

Commercial Solar Systems in Los Cabos and Baja California Sur

Commercial solar can reduce operating expenses, protect critical business equipment and improve energy resilience for restaurants, hotels, resorts, offices, retail properties, warehouses, farms and other commercial facilities.

Electricity is one of the largest ongoing expenses for many businesses in Baja California Sur. Air conditioning, refrigeration, pumps, lighting, kitchens, laundry equipment, computers and security systems may operate every day.

A professionally designed commercial solar system can reduce the amount of electricity purchased from CFE while creating a long-term business asset. Hybrid inverters and batteries can also support selected operations when the utility grid is unavailable.

Commercial solar design is more complicated than simply adding more panels. The system must account for service voltage, single-phase or three-phase power, peak demand, operating schedules, large motors, critical loads, roof or carport space and future business expansion.

Commercial solar should be treated as an operational investment. The system must support the way the business actually operates, not just produce an attractive panel count on a proposal.

How Cabo Solar Experts Evaluates a Commercial Property

A commercial proposal should begin with documented electricity usage, operating schedules and an inspection of the electrical service.

Review CFE consumption.
We review recent bills, historical kilowatt-hour usage, tariff information and seasonal changes.
Identify major equipment.
Refrigeration, air conditioning, pumps, motors, cooking equipment, laundry, lighting and office loads are documented.
Measure or estimate peak demand.
The highest simultaneous electrical demand affects inverter sizing and backup-system design.
Determine operating hours.
Businesses that use most of their electricity during daylight hours may receive strong value from direct solar consumption.
Identify critical loads.
The business must decide which equipment must continue operating during an outage.
Inspect the electrical service.
Voltage, phase configuration, distribution panels, transformers and available breaker capacity must be confirmed.
Evaluate installation space.
Roofs, carports, patio structures and ground-mounted areas are reviewed for panel placement.
Plan the project in phases if necessary.
Large systems may be installed in stages while preserving the final design.

Hotel Backup Strategy

A hotel may not need to back up every room and every appliance. It may be more practical to protect reception, communications, refrigeration, emergency lighting, water systems and selected guest areas.

Phased Hotel Solar

Large hospitality projects can be installed in planned sections. The first phase may serve common areas or daytime loads, while later phases expand guest-room production and battery capacity.

Solar for Offices and Professional Buildings

Office buildings commonly use most of their electricity during daylight hours, which aligns well with solar production.

Typical Office Loads

Air conditioning
Computers
Servers
Printers
Lighting
Internet equipment
Security systems
Conference-room equipment

Battery backup can support internet, communications, computers and security when CFE power is interrupted.

Common HOA Solar Projects

Common-area lighting
Pool pumps
Security gates
Water pumps
Clubhouses
Management offices
Solar carports
EV charging stations

HOA projects require clear approval procedures, defined ownership, maintenance responsibility and transparent financial analysis.

Solar for Schools, Clinics and Community Facilities

Schools and community facilities can benefit from daytime solar production because many operate primarily during sunlight hours.

Medical and professional facilities may require battery backup for communications, refrigeration, lighting and selected critical equipment.

Medical backup systems must be designed around the exact equipment and required operating duration. General package assumptions are not sufficient.

Commercial Three-Phase Solar Systems

Many commercial properties use three-phase electrical service because it can support larger motors and equipment more efficiently.

A three-phase solar system must be designed around the service voltage, phase configuration and distribution system.

Three-Phase Design Considerations

Utility service voltage
Phase-to-phase voltage
Phase-to-neutral voltage
Load balance
Transformer capacity
Inverter compatibility
Backup-load distribution
Generator phase configuration

A commercial building may use multiple inverters, one inverter per phase or another approved configuration.

Equipment should never be assumed to be three-phase compatible simply because several inverters can be connected together. Manufacturer approval and proper control architecture are required.

Commercial Battery Backup

Commercial batteries can protect critical operations, but the system must be designed around both energy capacity and maximum power demand.

Critical Commercial Loads

Refrigeration
Freezers
Point-of-sale systems
Internet
Security
Emergency lighting
Communications
Selected pumps
Selected air conditioning

Energy Capacity

Energy capacity determines how long the loads can operate.

Power Capacity

Power capacity determines how much equipment can operate at one time.

A battery bank may contain enough energy for several hours but still be unable to start a large compressor or motor without adequate discharge power.

Solar, Batteries and Business Continuity

A power outage can create costs beyond the CFE bill.

Possible Outage Costs

Lost refrigerated inventory
Lost food products
Closed business hours
Guest refunds
Internet and payment-system failure
Employee downtime
Security risks
Generator fuel expenses

Battery backup can reduce these risks by keeping critical systems operating.

The financial value of backup should include avoided business losses, not only energy savings.

Commercial Load Management

Load management reduces the amount of inverter and battery capacity required.

Common Load-Management Strategies

Operate pumps during peak solar hours
Stagger air-conditioning startup
Delay EV charging
Separate essential and nonessential circuits
Turn off selected kitchen equipment during outages
Use variable-speed motors
Reduce unnecessary overnight loads

Smart controls and operating procedures may reduce project cost while improving battery runtime.

Improve Efficiency Before Oversizing Solar

Reducing waste may be less expensive than installing additional solar panels and batteries.

Commercial Efficiency Opportunities

Replace old air conditioners
Use variable-speed pumps
Improve refrigeration seals
Clean condenser coils
Install LED lighting
Use occupancy controls
Improve insulation
Reduce water-heating losses
Repair compressed-air leaks
Schedule large loads during solar hours

Energy efficiency can reduce the required solar-array size and shorten the return-on-investment period.

Commercial Solar Return on Investment

Commercial solar ROI depends on current electricity expense, system cost, production, operating hours and changes in future energy use.

Example: 24,000 MXN CFE Bill Every 60 Days

24,000 MXN × 6 billing periods = 144,000 MXN per year

If solar reduces purchased electricity by 80%, estimated gross annual savings could be:

144,000 MXN × 80% = 115,200 MXN per year

Example: 50,000 MXN CFE Bill Every 60 Days

50,000 MXN × 6 = 300,000 MXN per year

An 80% reduction could represent estimated gross annual savings of:

300,000 MXN × 80% = 240,000 MXN per year

These examples do not include maintenance, financing, taxes, CFE fixed charges or changes in consumption.

Commercial ROI May Also Include

Avoided outage losses
Reduced generator fuel use
Improved guest experience
Protected inventory
Lower operating expenses
Potential property-value improvement

Commercial Solar Cost Per Watt

Cost per watt can be useful when comparing commercial proposals, but only when the proposals have a similar scope.

Total installed project price ÷ solar-array watts = installed cost per watt

A solar-only system should not be compared directly with a hybrid system that includes batteries, backup panels, generator integration and extensive electrical upgrades.

Example: 36 Panels at 615 Watts

36 × 615 watts = 22,140 watts
Total solar-array size = 22.14 kW DC

If the total installed project price is $47,000 USD:

$47,000 ÷ 22,140 watts = approximately $2.12 per watt

This price-per-watt figure includes more than solar panels when batteries, hybrid equipment and installation are part of the project.

Commercial Solar Installed in Phases

Phased solar allows a business to begin reducing energy expenses before purchasing the entire final system.

Example: 36-Panel System in Three Phases

Phase	Solar panels	Array added	Main objective
Phase 1	12 panels	7.38 kW	Begin savings and install the main hybrid infrastructure
Phase 2	12 additional panels	7.38 kW	Increase production and reduce CFE purchases further
Phase 3	12 additional panels	7.38 kW	Complete the 22.14 kW final system

Benefits of Phased Installation

Lower initial capital requirement
Earlier energy savings
Ability to use savings toward later phases
Reduced interruption to business operations
Flexibility as energy needs change

Critical Phased-Design Rule

The first phase must be designed for the completed final system. Main conductors, inverter capacity, panel space, battery platform and distribution equipment should be planned in advance.

Commercial Equipment and Labor Payment Structure

Cabo Solar Experts may separate equipment and labor payments so the customer clearly understands what is being purchased.

Typical Structure

Equipment payment is made before equipment is ordered
Labor is paid when equipment arrives and installation begins
Each phase has a separate equipment and labor amount
Additional work requires written approval
Permits and utility fees may be separate

Exact payment terms should always be stated in the written proposal.

Commercial Solar Monitoring and Maintenance

Commercial systems should be monitored because a small performance problem can create significant lost energy over time.

Recommended Monitoring

Daily and monthly solar production
Battery charging and discharge
Grid consumption
Inverter alarms
Communication status
Unexpected production declines

Recommended Physical Inspection

Panel damage
Loose racking
Corrosion
Damaged conduit
Water intrusion
Blocked ventilation
Animal damage
Excessive dust or salt buildup

Maintenance plans should reflect the property location, equipment and operating importance of the system.

Continue to Part 5: Solar Equipment and Product Guide

Part 5 will cover JA Solar 615-watt panels, LuxPower hybrid inverters, Lux batteries, Pylontech batteries, APsystems and Hoymiles microinverters, racking, surge protection, generator integration, EV chargers, monitoring equipment and the correct use case for each product.

Solar Equipment and Product Guide

A reliable solar system is built from components that are correctly matched, professionally installed and programmed to work together.

Solar panels, inverters, batteries, microinverters, racking, disconnects, breakers, monitoring equipment and surge protection each perform a different job.

A premium panel connected to an undersized inverter is not a premium system. An expensive battery connected to incompatible equipment is not a dependable backup system. The full design matters more than any single product name.

Cabo Solar Experts selects equipment according to property consumption, service voltage, backup requirements, installation conditions, expansion plans and equipment compatibility.

Equipment rule: Every panel, inverter, battery and protective device must be selected as part of one complete electrical system.

How Cabo Solar Experts Selects Solar Equipment

Equipment should not be selected only by price, brand recognition or the largest number printed on the product.

Electrical Compatibility

The solar-array voltage and current must remain within the inverter’s allowable input range. Batteries must match the inverter’s voltage and communication requirements.

Application

A small essential-backup system needs different equipment from a restaurant, luxury home, hotel or large off-grid property.

Power Requirements

The inverter must support the highest expected simultaneous load and the starting current of motors, pumps, compressors and air conditioners.

Energy Requirements

Battery capacity must support the desired loads for the required number of hours.

Operating Environment

Equipment installed in Los Cabos must operate in high heat, dust, salt air and seasonal storm conditions.

Expansion

The inverter, battery platform, electrical conductors and racking should allow future expansion when the customer plans to add energy capacity.

Support and Warranty

Equipment availability, technical support, distributor relationships and warranty procedures are important parts of product selection.

Correct voltage and current ratings
Compatible battery communication
Suitable inverter output
Local equipment availability
Remote monitoring capability
Expansion potential
Manufacturer and distributor support
Appropriate environmental ratings

JA Solar 615-Watt Solar Panels

Cabo Solar Experts commonly uses high-output JA Solar 615-watt modules for residential, commercial and off-grid installations.

High-wattage panels allow a system to reach a large solar capacity with fewer individual modules than a system using lower-wattage panels.

Fewer panels may reduce the amount of racking, roof attachments, wiring and installation labor required for a given system size.

Common Advantages of 615-Watt Panels

High power output per panel
Fewer panels needed for a large array
Useful for homes with limited installation space
Strong value for commercial projects
Suitable for roofs, carports and ground mounts
Efficient use of racking and installation labor

Array-Size Examples

Panel quantity	Panel wattage	Total DC array size	Typical application
4 panels	615 watts each	2.46 kW	Small expansion or limited-load system
8 panels	615 watts each	4.92 kW	Essential-backup residential package
12 panels	615 watts each	7.38 kW	Residential or phased commercial installation
16 panels	615 watts each	9.84 kW	Whole-home hybrid package
24 panels	615 watts each	14.76 kW	Large home or commercial system
36 panels	615 watts each	22.14 kW	Restaurant, hotel or high-consumption property

Important Panel Design Considerations

Panel dimensions and weight
Roof or structure capacity
Wind exposure
Inverter input-voltage limits
String current limits
Shade and orientation
Cleaning access
Drainage and maintenance pathways

High-wattage panels are physically large. Roof layout and structural conditions must be confirmed before the final panel count is approved.

Understanding Solar Panel Warranties

Solar panels commonly include two different types of warranty: a product warranty and a performance warranty.

Product Warranty

A product warranty generally covers qualifying defects in materials or manufacturing for the period stated by the manufacturer.

Performance Warranty

A performance warranty describes the expected long-term power output of the panel. Solar panels gradually lose a small amount of output over time.

What Panel Warranties May Not Cover

Improper installation
Storm or flying-debris damage
Roof failure
Damage from walking on panels
Animal damage
Unauthorized modification
Improper electrical design

Exact warranty terms depend on the specific panel model and distributor. Customers should receive the applicable warranty documentation.

Solar Inverters: The Control Center of the System

The inverter converts DC solar electricity into AC electricity and controls how power moves between solar panels, batteries, CFE and backup loads.

Inverter selection affects the amount of equipment that can operate, battery compatibility, generator integration, monitoring and future expansion.

Important Inverter Ratings

Continuous AC output
Short-term surge output
Maximum solar input power
Solar input-voltage range
Maximum input current
Battery-voltage range
Charging current
Grid and generator compatibility
Single-phase or three-phase capability
Monitoring and communication

Inverter Power Is Not Battery Capacity

A 12-kilowatt inverter describes how much AC power the inverter can deliver under its rated conditions. It does not mean the system has 12 kilowatt-hours of stored energy.

A large inverter connected to a small battery may run a large load for only a short time. A large battery connected to a small inverter may store substantial energy but be unable to operate multiple high-power loads at once.

LuxPower SNA 6K Hybrid Inverter

The LuxPower SNA 6K is commonly used for smaller residential, essential-backup and off-grid systems.

It can coordinate solar production, compatible low-voltage batteries, utility power and generator input when the system is designed and programmed correctly.

Common SNA 6K Applications

Small homes
Casitas
Essential-load backup
Refrigeration and lighting backup
One efficient mini-split, depending on load
Small off-grid homes
Expandable residential systems

Why the SNA 6K Is a Strong Starting Platform

A 6-kilowatt hybrid inverter can support many normal household loads without requiring the cost of a larger commercial-scale inverter.

It is useful for homeowners who want to begin with essential backup and add compatible batteries or panels later.

What Must Be Verified

Actual model voltage and frequency
Solar string configuration
Battery compatibility
Generator compatibility
Backup-panel load
Maximum motor-starting demand
Local service configuration

A 6-kilowatt inverter is not intended to operate every load in a large luxury home at the same time.

LuxPower SNA 12K Hybrid Inverter

The LuxPower SNA 12K provides greater inverter capacity for larger homes, businesses and off-grid properties with substantial electrical demand.

Common SNA 12K Applications

Large residential homes
Multiple air conditioners
Restaurants
Commercial kitchens
Large off-grid homes
Pool and water-pump systems
Phased commercial projects
Properties with substantial backup requirements

Advantages of Greater Inverter Capacity

A larger inverter can operate more simultaneous loads and support larger motor-starting requirements, assuming the batteries and electrical system are also sized correctly.

The SNA 12K can be a strong platform for a property that expects future growth, but installing a large inverter does not eliminate the need for load calculations.

Battery Requirements

A high-output inverter may require multiple compatible battery modules to provide enough discharge current and useful runtime.

Do not connect a large inverter to an undersized battery bank and assume the system will deliver full output for long periods.

LuxPower LXP-LB-US 8K Hybrid Inverter

The LuxPower LXP-LB-US 8K hybrid platform is commonly considered for whole-home solar and battery applications.

An 8-kilowatt inverter can provide a balance between smaller essential-backup systems and larger 12-kilowatt installations.

Common Applications

Medium-size homes
Whole-home hybrid systems
Vacation rentals
Selected air-conditioning backup
Pool-pump support
Expandable battery systems
Properties seeking major CFE reduction

Why Customers Choose an 8K Platform

It can support more household demand than a smaller essential-load inverter without automatically requiring the cost and battery capacity of the largest system.

Final suitability depends on service voltage, model specifications, backup loads and battery configuration.

LuxPower Inverter Comparison

Inverter	General size class	Common use	Important limitation
LuxPower SNA 6K	Approximately 6 kW	Essential backup, small homes and casitas	Not intended for every load in a large home
LuxPower LXP-LB-US 8K	Approximately 8 kW	Medium homes and whole-home hybrid applications	Large simultaneous loads still require management
LuxPower SNA 12K	Approximately 12 kW	Large homes, businesses and off-grid properties	Requires an appropriately sized battery bank

These are general application descriptions. Exact equipment ratings and installation requirements must be confirmed from the current manufacturer documentation for the selected model.

Lithium Battery Storage Guide

Batteries store energy, support backup loads and allow solar electricity to be used when the sun is not shining.

Battery systems should be compared using more than nameplate kilowatt-hours.

Important Battery Specifications

Electrical Balance-of-System Equipment

The equipment customers do not see in advertisements is often what determines whether the system is safe and reliable.

Common Balance-of-System Components

PV wire
AC conductors
Battery cables
Conduit
Junction boxes
Combiner boxes
Breakers
Fuses
AC disconnects
DC disconnects
Grounding equipment
Current transformers
Communication cables
Labels
Surge protection

Why Wire Size Matters

Conductors must be sized for current, distance, temperature, installation method and allowable voltage drop.

Undersized wiring can create excessive heat, poor performance and fire risk.

Why Breaker Size Matters

Breakers protect conductors and equipment. Installing a larger breaker does not safely increase the power capacity of undersized wiring.

Whole-Home and Solar Surge Protection

Surge protection can provide an additional layer of protection for inverters, appliances and sensitive electronics.

Electrical surges may come from utility disturbances, switching events, nearby lightning and large motors.

Surge Protection May Be Installed At

Main electrical service
Solar AC connection
DC solar input
Critical-load panel
Communication equipment

Surge protection reduces risk but cannot guarantee protection against every lightning or electrical event.

Generator Integration Equipment

Generator integration may require more than connecting a cable to the inverter.

Possible Generator Components

Generator breaker
Manual transfer switch
Automatic transfer equipment
Generator isolation contactor
Automatic-start controls
Charging-current programming
Grounding and neutral coordination
Monitoring and alarms

Generator voltage, frequency, waveform, grounding and fuel capacity must be compatible with the hybrid system.

Electric Vehicle Chargers

EV charging can be integrated with residential, hotel, commercial and solar-carport projects.

EV Charger Design Must Consider

Vehicle charging requirements
Electrical-service capacity
Charger current
Distance from the electrical panel
Weather exposure

Monitoring allows the customer and installer to review system production, battery state and equipment alarms.

Monitoring May Show

Current solar output
Daily energy production
Battery state of charge
Battery charging and discharge
Grid consumption
Backup-load consumption
Generator operation
Inverter faults
Communication status

Monitoring Limitations

Monitoring depends on internet connectivity, communication equipment and correct configuration.

A loss of monitoring does not always mean the solar system has stopped producing, but it should be investigated.

Critter Guards and Animal Protection

Birds and small animals may nest below solar panels and damage wiring.

Critter guards create a barrier around the array while preserving airflow under the panels.

Critter Guards Can Help Reduce

Bird nesting
Chewed wiring
Debris accumulation
Animal access
Maintenance problems

Guards must not damage the panels or prevent necessary drainage and ventilation.

Part 6 will explain how to read a CFE bill, kilowatt-hours, billing periods, residential and commercial consumption, DAC pricing, demand, solar offsets, CFE savings, sample calculations and return on investment.

The Complete CFE Electricity Guide for Solar Customers

Understanding a CFE electricity bill is the first step toward designing a solar system that accurately matches a home or business in Los Cabos and Baja California Sur.

A solar proposal should not be based only on the total peso amount shown on one bill. The bill also contains electricity consumption, billing dates, tariff information, meter readings, service details and other information needed to evaluate the property.

The most important energy number is normally the total number of kilowatt-hours consumed during the billing period. That number shows how much electrical energy the property used.

The peso total alone can be misleading because electricity charges may include different consumption blocks, fixed charges, taxes, adjustments or demand-related charges. Rates and tariff rules may also change.

Solar-sizing rule: Design the system from documented kilowatt-hour consumption and actual electrical loads—not from the peso total alone.

What Information Appears on a CFE Bill?

The appearance of a CFE bill may change, and residential and commercial bills may contain different fields. However, customers should generally look for the following information.

👤

Customer Information

The bill identifies the registered service holder and the address associated with the electricity account.

#

Service Number

The service number identifies the CFE account and is commonly used for payments, inquiries and account management.

⚡

Tariff

The tariff identifies the general billing structure applied to the property.

📅

Billing Period

The start and end dates show the period over which electricity consumption was measured.

🔢

Meter Readings

Current and previous meter readings are used to calculate energy consumption.

💡

Kilowatt-Hours

Kilowatt-hours show the amount of electrical energy used during the billing period.

💰

Energy Charges

The bill may divide consumption among different billing blocks or charge categories.

📊

Consumption History

Historical data can reveal seasonal changes and long-term energy trends.

🏭

Demand Information

Some business tariffs may include measured or billed electrical demand in addition to energy consumption.

What Is a Kilowatt-Hour?

A kilowatt-hour is a measurement of electrical energy.

One kilowatt-hour represents the energy used by a 1,000-watt load operating for one hour.

Simple Example

1,000 watts × 1 hour = 1 kilowatt-hour

Five-Hundred-Watt Example

500 watts × 2 hours = 1 kilowatt-hour

Air-Conditioner Example

If an air conditioner averages 1.2 kilowatts while operating for eight hours:

1.2 kW × 8 hours = 9.6 kWh per day

Over 30 days, that simplified example would represent:

9.6 kWh × 30 days = 288 kWh per month

Real air-conditioning consumption changes as the compressor cycles and operating conditions change.

Kilowatts Versus Kilowatt-Hours

Kilowatts and kilowatt-hours describe different things.

Measurement	What it describes	Solar example
Kilowatts	Power available or used at a specific moment	A 12 kW inverter can deliver a rated amount of power
Kilowatt-hours	Energy produced, consumed or stored over time	A 5.12 kWh battery stores a rated amount of energy

A large inverter does not automatically provide long battery runtime. Battery duration depends on stored kilowatt-hours and the electrical load.

How CFE Meter Readings Relate to Consumption

Electricity consumption is generally calculated from the difference between meter readings, subject to the meter configuration and billing method.

Simple Meter Example

Current meter reading: 18,500
Previous meter reading: 16,700

18,500 − 16,700 = 1,800 kWh consumed

Some meters, transformers or commercial services may use multipliers or more complex measurement methods.

When the bill includes estimated rather than verified consumption, the customer should confirm the meter and account information before using that bill as the only basis for a solar proposal.

Understanding the CFE Billing Period

Residential CFE bills are often issued for a period covering approximately two months, although the exact dates should always be checked.

Commercial billing periods may differ. Never assume the number of days without reading the dates printed on the bill.

Why Billing-Period Length Matters

A customer who uses 1,800 kWh over 60 days has a different average daily consumption from a customer who uses 1,800 kWh over 30 days.

Sixty-Day Example

1,800 kWh ÷ 60 days = 30 kWh per day

Thirty-Day Example

1,800 kWh ÷ 30 days = 60 kWh per day

The second property has approximately twice the average daily energy consumption despite showing the same total kilowatt-hours.

How to Calculate Average Daily Electricity Consumption

Average daily consumption provides a useful starting point for estimating solar-array size.

Billing-period kilowatt-hours ÷ number of billing days = average daily kWh consumption

Example: 2,400 kWh Over 60 Days

2,400 kWh ÷ 60 = 40 kWh per day

Example: 5,760 kWh Over 60 Days

5,760 kWh ÷ 60 = 96 kWh per day

Average daily consumption does not reveal the highest simultaneous load. Inverter sizing also requires an evaluation of appliances, motors, air conditioners and commercial equipment.

Why Twelve Months of CFE Bills Are Better Than One Bill

One bill may represent an unusually hot, cool, busy or unoccupied period.

Solar is a long-term investment, so annual consumption provides a more dependable basis for system sizing than one isolated billing cycle.

Seasonal Changes May Be Caused By

Summer air conditioning
Vacation-home occupancy
Tourist seasons
Restaurant business cycles
Pool heating
Hotel occupancy
Irrigation requirements
Holiday lighting
Construction activity

Annual Consumption Calculation

Add the kilowatt-hours from all billing periods covering approximately twelve months.

Total annual kWh ÷ 365 = average daily annual consumption

The design should also consider the months with the highest consumption, especially when battery backup is important.

Understanding Residential CFE Tariffs

Residential electricity may be billed under different domestic tariff structures depending on location, climate classification and consumption.

Domestic tariffs may divide electricity use into basic, intermediate and excess-consumption blocks. The exact limits and prices depend on the applicable tariff and current published schedule.

Some climate-based domestic tariffs recognize locations with high summer temperatures. The exact tariff assigned to the account should be read directly from the CFE bill.

Residential Tariff Questions to Ask

What tariff appears on the bill?
Is the account classified as domestic?
Does the bill show basic, intermediate and excess consumption?
Is the property approaching high-consumption classification?
Has the tariff changed recently?
Does the consumption history match the property’s real occupancy?

CFE tariffs and charges can change. Confirm current tariff information through official CFE sources before publishing a guaranteed savings calculation.

What Is the CFE DAC Tariff?

DAC means Domestic High Consumption and applies to qualifying residential services whose average consumption exceeds the high-consumption limit established for the applicable domestic tariff.

DAC classification is important because customers may lose the benefit of subsidized domestic pricing and face substantially higher electricity costs.

CFE determines average monthly consumption using a moving average over the preceding twelve months. The high-consumption limit depends on the underlying domestic tariff assigned to the property.

Why Customers Enter DAC

Heavy air-conditioning use
Multiple residences on one meter
Pool pumps and pool heating
Electric water heating
Electric cooking
Large vacation homes
Guest casitas
Vacation-rental occupancy
Electric vehicle charging
Inefficient appliances

Why Solar Can Be Valuable for DAC Customers

DAC customers often have high annual electricity expenses. Reducing grid consumption may create substantial long-term savings.

Solar design for DAC customers should focus on annual consumption and the moving average, not only one high bill.

Can Solar Help a Home Leave DAC?

Solar may help reduce electricity measured from the grid, but leaving DAC is not necessarily immediate.

Because DAC status is based on a moving consumption average, the account may need enough lower-consumption billing periods for that average to fall below the applicable high-consumption limit.

Factors Affecting the Process

Previous twelve months of consumption
Applicable domestic tariff
Current household consumption
Solar production
Interconnection and metering behavior
New electrical loads
Seasonal air-conditioning demand

Never promise a specific date for leaving DAC without verifying the account history and current CFE rules.

Basic, Intermediate and Excess Consumption

Some residential tariffs divide consumed electricity into billing blocks.

Basic Consumption

The first portion of energy use may be billed within a basic block.

Intermediate Consumption

The next portion may be billed within one or more intermediate blocks.

Excess Consumption

Consumption above the lower blocks may be billed at an excess-consumption rate.

The exact block limits and current charges depend on the tariff and published schedule.

Why This Matters for Solar

The first solar-generated kilowatt-hours may offset the most expensive grid energy when the customer has substantial excess consumption.

However, savings should be modeled using the customer’s actual bill and current tariff instead of multiplying every solar kilowatt-hour by one assumed rate.

Understanding Commercial CFE Tariffs

Business tariffs may be based on service voltage, maximum demand, energy consumption and other electrical characteristics.

A small business connected at low voltage with limited demand may have a different tariff from a larger commercial facility with high demand or a medium-voltage service.

Commercial solar analysis must review the exact tariff shown on the bill.

Common Commercial Billing Elements

Kilowatt-hour energy consumption
Maximum or billed demand
Service voltage
Fixed charges
Power factor, where applicable
Time-related energy categories, where applicable
Taxes and adjustments

Commercial tariffs and labels may change. The account’s current bill and official CFE tariff information should control the analysis.

Small-Demand Low-Voltage Business Service

CFE publishes a low-voltage business tariff category for smaller-demand services within its stated demand limit.

This type of account may be used by smaller stores, offices, restaurants, workshops and other businesses, depending on the actual service characteristics.

Solar Considerations

Daytime operating schedule
Air-conditioning consumption
Refrigeration
Maximum simultaneous load
Available roof or carport space
Single-phase or three-phase service
Backup requirements

The tariff name should be confirmed directly from the current bill.

What Is Electrical Demand?

Energy consumption measures how much electricity is used over time. Demand measures how much power is required during a defined interval.

Simple Example

A business operating ten 2-kilowatt air conditioners at the same time may create approximately 20 kilowatts of cooling demand before adding lighting, refrigeration and other loads.

10 air conditioners × 2 kW = 20 kW of simultaneous demand

If those air conditioners operate for five hours, they would use:

20 kW × 5 hours = 100 kWh of energy

Why Demand Matters

It affects service and transformer loading
It affects inverter capacity
It affects generator sizing
It may affect commercial billing
It determines how many loads can operate together

Reducing Commercial Peak Demand

Solar may reduce daytime grid demand, but performance depends on whether solar production occurs at the same time as the property’s demand peak.

Demand-Management Strategies

Stagger air-conditioner startup
Operate pumps during strong solar production
Delay EV charging
Use variable-speed motors
Control water-heating schedules
Avoid starting several compressors simultaneously
Use batteries to support selected demand peaks
Improve equipment efficiency

Demand savings should not be guaranteed without interval measurements or adequate information about the property’s load profile.

Power Factor and Commercial Electricity

Power factor describes how effectively electrical current is converted into useful work in an AC system.

Motors, transformers and other inductive equipment can contribute to poor power factor.

Some commercial accounts may receive charges or credits related to power factor under applicable rules.

Equipment That May Affect Power Factor

Large motors
Air-conditioning compressors
Pumps
Transformers
Industrial machinery
Older lighting systems

Power-factor correction should be designed by qualified electrical professionals using actual measurements.

Solar installation does not automatically correct every power-factor issue at a commercial property.

How Grid-Connected Solar Interacts with CFE

A grid-connected solar system supplies electricity to the property while operating in parallel with the utility service.

When solar production is lower than the property’s consumption, the property may purchase the remaining electricity from CFE.

When solar production exceeds immediate consumption, system behavior depends on the approved interconnection arrangement, meter configuration and current utility rules.

Possible System Approaches

Grid-tied solar with utility interconnection
Hybrid solar with utility interaction
Zero-export or export-limited operation
Off-grid operation without CFE interaction

The installer should confirm the current process and requirements before promising how exported energy will be measured or credited.

What Is a Bidirectional Meter?

A bidirectional meter can measure electricity flowing in more than one direction, depending on the approved system and meter configuration.

It may record electricity imported from the grid and electricity exported by the solar system.

Important Meter Questions

Has the solar system been formally approved?
Is the installed meter appropriate for the interconnection?
Does the bill show imported and exported energy?
Are the readings consistent with inverter monitoring?
Has the customer changed consumption after installation?

Do not energize an exporting grid-connected system without completing the required utility and electrical process.

What Is a Zero-Export Solar System?

A zero-export system is designed to prevent or limit electricity from being sent to the utility grid.

Current transformers or other sensors measure power at the utility connection. The inverter then adjusts its output to keep export within the programmed limit.

Zero-Export Components May Include

Compatible hybrid inverter
Current transformers
Energy meter
Communication wiring
Correct sensor orientation
Export-limit programming
Commissioning under changing loads

Common Zero-Export Problems

Current transformers installed backward
Sensors installed on the wrong conductors
Incorrect phase assignment
Communication failure
Incorrect inverter settings
Loads located outside the measured point

How Solar Offsets CFE Electricity Use

Solar reduces grid purchases when solar production supplies energy that the property would otherwise purchase from CFE.

Direct Self-Consumption

Solar electricity is used immediately by active property loads.

Battery Charging

Extra solar may charge batteries for later use.

Grid Export

Where approved, surplus energy may be exported according to the current interconnection arrangement.

Solar Offset Percentage

Estimated annual solar energy used or credited ÷ annual property consumption × 100 = estimated solar offset percentage

Example

If a property consumes 18,000 kWh annually and the system provides an estimated 14,400 kWh of useful annual offset:

14,400 ÷ 18,000 × 100 = 80% estimated annual offset

Why a Solar System May Not Offset 100% of the CFE Bill

A system may produce substantial electricity without eliminating every charge on the bill.

Possible Reasons

Fixed or minimum charges
Taxes or adjustments
Consumption increased after installation
Seasonal air-conditioning use
Shading or dirty panels
Inverter downtime
Export limitations
Battery charging losses
System intentionally sized below total consumption
Billing or meter timing differences

Customers should judge performance using both CFE bills and inverter monitoring over an appropriate period.

Estimating Solar Size from a CFE Bill

A simplified estimate begins by calculating average daily consumption.

Step 1: Find Billing-Period Consumption

Example consumption: 3,000 kWh

Step 2: Count Billing Days

Example billing period: 60 days

Step 3: Calculate Daily Consumption

3,000 kWh ÷ 60 = 50 kWh per day

Step 4: Estimate Required Solar Capacity

If the preliminary planning assumption is five useful daily kilowatt-hours of energy per installed kilowatt:

50 kWh ÷ 5 = 10 kW of preliminary solar capacity

Step 5: Adjust for Real Conditions

Panel temperature
Inverter losses
Wiring losses
Orientation
Shading
Dust and salt
Seasonal weather
Desired offset

This is a preliminary calculation, not final engineering.

Converting Required Solar Capacity into 615-Watt Panels

Once the preliminary array size is known, divide the required watts by the panel wattage.

Ten-Kilowatt Example

10,000 watts ÷ 615 watts = 16.26 panels

A practical design may use 17 panels for 10.455 kW or another panel count that fits the inverter and roof layout.

Twenty-Kilowatt Example

20,000 watts ÷ 615 watts = 32.52 panels

A practical design might use 32, 33, 36 or another compatible panel count.

Thirty-Six-Panel Example

36 × 615 watts = 22.14 kW DC

Estimating Solar Energy Production

Preliminary production can be estimated by multiplying array size by expected effective solar hours and an adjustment factor.

Array size × effective solar hours × system-efficiency factor = estimated daily production

Example: 9.84 kW Array

Using five effective hours and an illustrative 80% system factor:

9.84 kW × 5 × 0.80 = approximately 39.36 kWh per day

Example: 22.14 kW Array

22.14 kW × 5 × 0.80 = approximately 88.56 kWh per day

These are simplified illustrations, not production guarantees. Actual site modeling should use location, orientation, tilt, shade, temperature and equipment specifications.

How to Estimate CFE Savings

The simplest preliminary savings calculation begins with the customer’s annual electricity expense and estimated reduction percentage.

Example: 8,000 MXN Every 60 Days

8,000 MXN × 6 bills = 48,000 MXN per year

At an estimated 75% reduction:

48,000 × 0.75 = 36,000 MXN estimated gross annual savings

Example: 20,000 MXN Every 60 Days

20,000 × 6 = 120,000 MXN per year

At an estimated 80% reduction:

120,000 × 0.80 = 96,000 MXN estimated gross annual savings

A more accurate analysis applies current tariff charges to the energy blocks or commercial billing elements expected to be offset.

Calculating Simple Solar Payback

Simple payback estimates how long gross savings may take to equal the original project investment.

Total project price ÷ estimated annual savings = simple payback period

Example

Assume a system costs 400,000 MXN and produces estimated annual savings of 80,000 MXN:

400,000 ÷ 80,000 = 5-year simple payback

Simple Payback Does Not Automatically Include

Maintenance
Financing costs
Equipment replacement
Electricity-price changes
Taxes
Insurance
Battery replacement
Property-value effects
Avoided outage losses

Do Batteries Reduce CFE Bills?

Batteries can reduce grid consumption in some operating strategies, but their primary value may be backup power and energy control.

Batteries May Help By

Storing extra daytime solar
Supplying evening loads
Reducing selected grid purchases
Supporting demand management
Providing backup during outages

Battery Losses

Charging and discharging a battery creates energy losses. Using solar directly is generally more efficient than storing it first.

Financial Evaluation

Customers should separate the value of energy savings from the value of outage protection.

A battery may be worthwhile even when its direct bill savings do not produce the fastest payback, especially for businesses that face expensive outage losses.

How to Review a CFE Bill After Solar Installation

Compare several billing periods rather than judging performance from one bill.

Review These Items

Total grid consumption
Exported energy, where applicable
Billing-period dates
Tariff classification
Fixed and energy charges
Solar-monitoring production
Battery activity
Changes in property consumption

Common Reasons for Unexpected Bills

New air conditioners
Greater property occupancy
Pool-heating use

CFE and Solar Frequently Asked Questions

What number on my CFE bill is most important for solar?

Total kilowatt-hour consumption is one of the most important values. Billing dates, tariff and historical consumption are also necessary.

Can you size solar from the peso total?

Not accurately. The peso total may include different rates, taxes and charges. Kilowatt-hour consumption is required.

What does DAC mean?

DAC means Domestic High Consumption. It applies to qualifying residential accounts whose moving average consumption exceeds the applicable high-consumption limit.

Can solar help me leave DAC?

Solar may reduce grid consumption, but DAC status uses a moving consumption average. The change may take time.

How many CFE bills should I provide?

Twelve months is best. One recent bill can provide a preliminary estimate but may not represent seasonal consumption.

Why does my CFE bill increase in summer?

Air-conditioning use commonly increases during hot weather. Pool equipment and property occupancy may also increase consumption.

What is a kilowatt-hour?

A kilowatt-hour is an energy measurement equal to using one kilowatt of power for one hour.

What is electrical demand?

Demand measures how much power is required during a defined period. It differs from total energy consumption.

Can commercial solar reduce demand charges?

It may reduce certain daytime demand, but results depend on the load profile, solar production and tariff structure.

What is a bidirectional meter?

A bidirectional meter can measure electricity imported from and exported to the grid under an approved configuration.

What is zero export?

Zero export uses compatible controls and sensors to limit electricity sent to the utility grid.

Will solar make my CFE bill zero?

Not necessarily. Fixed charges, taxes, usage changes and system performance may leave a remaining balance.

Why is my bill still high after installing solar?

Possible causes include increased consumption, system faults, shading, dirty panels, tariff changes or incorrect expectations.

Do batteries eliminate CFE charges?

Not automatically. Batteries store energy and provide backup, but they also create conversion losses and have limited capacity.

How do I calculate average daily consumption?

Divide the billing-period kilowatt-hours by the number of days in the billing period.

How do I estimate simple solar payback?

Divide the total project investment by estimated annual savings. This simplified calculation does not include every financial factor.

Can Cabo Solar Experts review my CFE bill?

Yes. Send clear copies of your bills, property location and major load information for a preliminary solar evaluation.

Basic Solar Energy Questions

What is solar energy?

Solar energy is energy produced from sunlight. Photovoltaic solar panels convert sunlight into DC electricity. An inverter converts that electricity into AC electricity used by homes and businesses.

How do solar panels produce electricity?

Solar panels contain photovoltaic cells. Sunlight causes electrical activity inside those cells, producing direct-current electricity that is sent to an inverter.

Do solar panels need direct sunlight?

Solar panels produce the most electricity in direct sunlight. They may still produce reduced electricity during cloudy conditions, but shade and weak light lower output.

Do solar panels produce electricity at night?

No. Solar panels require sunlight. At night, electricity must come from batteries, CFE or a generator.

What is the difference between watts and kilowatt-hours?

Watts and kilowatts measure power at a specific moment. Kilowatt-hours measure energy produced, consumed or stored over time.

What does a 10 kW solar system mean?

It means the solar panels have a combined rated capacity of approximately 10,000 watts under standardized test conditions. Actual production changes with sunlight, temperature, shade and equipment losses.

How much electricity does one 615-watt panel produce?

Production depends on sunlight, heat, orientation, shading and system efficiency. A 615-watt rating describes maximum laboratory output, not guaranteed daily energy.

How many 615-watt panels make 5 kW?

Eight panels equal 4.92 kW. Nine panels equal 5.535 kW. The practical count must also fit the inverter’s voltage and current limits.

How many 615-watt panels make 10 kW?

Sixteen panels equal 9.84 kW. Seventeen panels equal 10.455 kW.

How large is a 36-panel system using 615-watt panels?

Thirty-six 615-watt panels equal 22,140 watts, or 22.14 kW DC.

Is solar effective in Los Cabos?

Yes. Los Cabos receives strong sunlight through much of the year. Final results still depend on heat, shade, orientation, dust, equipment and system design.

Does extreme heat improve solar-panel production?

Strong sunlight helps production, but excessive panel temperature can reduce voltage and instantaneous output. Proper airflow beneath the panels is important.

Solar Panel Questions

How long do solar panels last?

Quality solar panels are designed to produce electricity for decades. Their output normally declines gradually over time.

Do solar panels stop working after 25 years?

Not necessarily. A performance warranty period does not mean the panel immediately stops working. Many panels continue producing electricity after that period at reduced output.

Are 615-watt panels too large for a residential roof?

They can be used on residential roofs when panel dimensions, weight, roof structure, access and wind exposure are acceptable.

Can solar panels be installed on a flat concrete roof?

Yes. The design must address mounting, wind, drainage, waterproofing, panel tilt, row spacing and roof access.

Can panels be installed on a tile roof?

Yes, but the attachment method must protect the tile and connect safely to the underlying structure.

Can solar panels be installed on a metal roof?

Yes. Mounting depends on the metal-roof profile, seams, structure, corrosion conditions and manufacturer-approved attachment methods.

Can solar panels be installed on the ground?

Yes. Ground-mounted systems can provide flexible orientation and easier maintenance but require land, foundations, protection and electrical trenching.

Can panels be installed on a carport?

Yes. Solar carports provide vehicle shade and electricity. The structure must be engineered for wind, panel weight, foundations, vehicle clearance and drainage.

Can panels be installed on a patio cover?

Yes. A solar patio cover must be designed as a structural solar system rather than a lightweight shade structure.

Can solar panels be used as the patio roof?

They may form part of the roof system, but water management, panel gaps, drainage, structural loads and electrical safety must be addressed.

Does shade affect only the shaded panel?

It depends on the system. Shade can affect an entire string in some designs. Microinverters or optimizers may reduce the effect on other panels but cannot replace missing sunlight.

Do solar panels need to face south?

South-facing panels often provide strong annual output in the Northern Hemisphere, but east- and west-facing arrays can also provide valuable production.

What is the best panel direction for afternoon air conditioning?

West-facing panels may produce more electricity later in the afternoon. Final layout should consider the full annual load and available roof space.

Do solar panels need cleaning?

Yes, when dust, salt, bird residue or other material significantly blocks sunlight. Cleaning frequency depends on location and measured production loss.

Can I pressure-wash solar panels?

High-pressure washing may damage seals, wiring or glass and should generally be avoided unless specifically approved by the manufacturer.

Can someone walk on solar panels?

Walking on panels should be avoided. It can damage the glass, frame or internal cells and may void warranty coverage.

Solar Inverter Questions

What does a solar inverter do?

It converts DC electricity from solar panels or batteries into AC electricity used by normal household and commercial equipment.

What is a hybrid inverter?

A hybrid inverter manages solar panels, batteries, CFE electricity and sometimes a generator within one coordinated system.

What is a grid-tied inverter?

A grid-tied inverter operates in parallel with the utility and is primarily designed to reduce electricity purchased from the grid.

What is an off-grid inverter?

An off-grid inverter provides AC power without relying on a utility connection, generally using solar panels, batteries and generator support.

What size inverter does a small home need?

It depends on the highest simultaneous load. A smaller home may use a 6 kW-class inverter, but actual appliances and motor-starting requirements must be checked.

Is a 6 kW inverter enough for air conditioning?

It may support one or more efficient units depending on their running power, starting current and other simultaneous loads.

Is a 12 kW inverter enough for a large house?

It may be appropriate, but large air conditioners, ovens, pumps, pool equipment and EV chargers can still exceed its output when used together.

Can two inverters be installed together?

Some inverter platforms support parallel or multi-inverter operation. The exact models, firmware and control architecture must be approved for that configuration.

Can one inverter power different electrical phases?

It depends on the inverter and electrical service. Single-phase, split-phase and three-phase systems require different equipment and wiring.

Why does an inverter reduce output when it gets hot?

Inverters may thermally derate to protect internal components. Shade, ventilation and required clearances help control temperature.

Where should an inverter be installed?

In a protected, ventilated, serviceable location that complies with the manufacturer’s environmental and clearance requirements.

Can an inverter be installed in direct sunlight?

Even weather-rated equipment may perform better and last longer when protected from intense direct afternoon sun.

Why does my inverter show a fault?

Possible causes include grid conditions, battery communication, excessive load, temperature, solar-input problems, wiring faults or internal equipment issues.

Should I repeatedly reset an inverter fault?

No. Repeated faults should be diagnosed. Continually resetting equipment without finding the cause can be unsafe or cause further damage.

Solar Battery Questions

What does a solar battery do?

It stores electricity for use when solar production is low, at night or during a utility outage.

How much energy does a 5.12 kWh battery store?

Its nameplate capacity is approximately 5.12 kilowatt-hours. Usable energy may be lower because of reserve settings, conversion losses and battery-protection limits.

How long will one 5.12 kWh battery last?

Runtime depends on the load. A 500-watt average load theoretically uses about 0.5 kWh each hour, but actual runtime is reduced by losses and reserve settings.

Can one battery run a refrigerator all night?

Often yes, along with selected small loads, depending on the refrigerator, battery condition and other consumption.

Can one battery run an air conditioner all night?

Usually not for an entire night unless the air conditioner is very efficient and the load is low. Accurate runtime requires measured consumption.

How many batteries do I need for whole-home backup?

The answer depends on the home’s average and peak loads, desired outage duration and which high-power appliances will operate.

Can I add batteries later?

Often yes, when the system is expandable. Battery model, age, firmware, communication and manufacturer limits must be checked.

Can different battery brands be mixed?

It is generally a bad idea unless the inverter and battery manufacturers specifically approve the combination.

Can old and new batteries be mixed?

Sometimes, but differences in age, capacity and internal resistance may create imbalance. Manufacturer guidance should control.

How long do lithium solar batteries last?

Battery life depends on temperature, depth of discharge, cycle frequency, charging settings and operating conditions.

Does heat damage lithium batteries?

Excessive heat can shorten battery life. Batteries should be kept within the manufacturer’s specified operating range.

Can solar batteries be installed outdoors?

Only when the specific battery and enclosure are rated for the environment and installed according to manufacturer instructions.

Can batteries be installed in a bedroom?

Equipment location must follow manufacturer instructions and applicable safety requirements. A bedroom is generally not the first choice for large battery equipment.

Can batteries be installed in a garage?

Often yes, when protected from heat, flooding, vehicles and physical damage and when required clearances are maintained.

What is battery state of charge?

State of charge estimates how much energy remains in the battery, usually displayed as a percentage.

What battery reserve should I use?

Reserve settings depend on whether the priority is maximum daily savings, emergency backup or battery-life protection.

Can CFE charge my batteries?

Many hybrid inverters can charge batteries from the utility when programmed to do so.

Can a generator charge my batteries?

Many hybrid systems support generator charging when voltage, frequency, grounding, power and controls are compatible.

Power Outage and Backup Questions

Will ordinary grid-tied solar work during a blackout?

Normally no. Grid-tied inverters shut down during an outage to prevent dangerous power from being sent onto utility lines.

What equipment allows solar to work during an outage?

A compatible hybrid inverter, battery bank, transfer equipment and properly arranged backup circuits are generally required.

Will the power switch instantly to batteries?

Many hybrid systems transfer very quickly, but exact transfer time and behavior depend on the equipment and wiring.

Can my whole house stay on during an outage?

It may, but the inverter and batteries still have limits. High-power loads may need to be turned off or managed.

What loads should be backed up first?

Refrigeration, internet, security, lighting, medical devices, communications and essential water pumps are common priorities.

Should pool heaters be backed up?

Usually not unless the system is specifically designed for the very large energy requirement.

Should an EV charger be backed up?

It is usually disabled during outages to preserve stored energy for the home or business.

Can solar recharge batteries during a long outage?

Yes, when the system is designed to operate in backup mode and sufficient sunlight is available.

What happens when the battery becomes empty?

The inverter may shut down backup loads, switch to CFE or start or request generator support, depending on the design.

Can I manually turn off unnecessary loads during an outage?

Yes. Load reduction is one of the easiest ways to extend battery runtime.

Air-Conditioning and Solar Questions

Can solar panels run air conditioning?

Yes. Solar can support air conditioning during sunny hours when the array and inverter are correctly sized.

Can batteries run air conditioning after sunset?

Yes, but nighttime air conditioning can require substantial battery storage.

How much power does a mini-split use?

Consumption varies by capacity, efficiency, temperature, insulation, thermostat setting and compressor speed. Measure or check the actual unit specifications.

Are inverter mini-splits better for solar?

Variable-speed mini-splits are often easier to support because they can reduce power after reaching the desired temperature.

Can one 12 kW inverter run five mini-splits?

Possibly, but only after checking the actual simultaneous operating power and other loads. Panel size and battery capacity must also be sufficient.

Why does my air conditioner drain the battery quickly?

Cooling requires significant energy, especially during hot weather, with poor insulation or low thermostat settings.

How can I reduce air-conditioning energy use?

Improve insulation, seal air leaks, shade windows, clean filters, use efficient equipment and cool only occupied areas.

Should I replace old air conditioners before buying more solar?

Often yes. Replacing inefficient cooling equipment may cost less than adding enough panels and batteries to support the wasted energy.

Pool, Pump and Water-System Questions

Can solar power a pool pump?

Yes. Pool pumps are excellent daytime solar loads because they can usually operate during strong sunlight.

Should a pool pump run at night?

Running during sunny hours generally reduces battery use and grid purchases. The exact schedule depends on pool requirements.

Are variable-speed pool pumps worth it?

They can reduce electricity consumption substantially when correctly sized and programmed.

Can solar power a pool heat pump?

Yes, but pool heat pumps can use significant energy. Pool size, water temperature, outdoor conditions and operating hours must be included.

Can solar power a well pump?

Yes, when inverter capacity, pump voltage, horsepower, starting current and daily water requirements are evaluated.

Can solar power a pressure pump?

Yes. The inverter must support the pump’s starting surge and the system must have enough energy for expected operating time.

Why does a pump require more power when it starts?

Many motors draw a brief surge of current while starting. The inverter must support this surge.

CFE Bill and Savings Questions

What part of my CFE bill is used to size solar?

Kilowatt-hour consumption, billing dates, tariff and historical use are the most useful starting points.

Can solar be sized from the amount I paid?

Not accurately. The peso total may include different rates, taxes, fixed charges and adjustments.

How many CFE bills should I provide?

Twelve months is best. One bill can provide a preliminary estimate but may not represent seasonal consumption.

What does DAC mean?

DAC means Domestic High Consumption. It applies to residential accounts that exceed the applicable moving-average consumption limit.

Can solar help reduce DAC electricity expenses?

Yes. DAC customers often have high energy costs and may receive strong value from reducing grid consumption.

Will solar immediately remove a property from DAC?

Not necessarily. DAC classification uses a moving historical consumption average, so a change may take time.

Will my CFE bill become zero?

Not always. Fixed charges, taxes, increased use, system performance and current utility rules may leave a balance.

Why did my bill remain high after installing solar?

Possible causes include increased consumption, equipment faults, shading, dirty panels, incorrect meter configuration or unrealistic original estimates.

What is a bidirectional meter?

It is a meter capable of measuring electricity flowing to and from the grid under an approved solar interconnection.

What is zero export?

Zero export uses sensors and inverter controls to limit power sent from the property to the utility grid.

How are solar savings calculated?

Savings estimates use electricity consumption, current charges, expected solar production, self-consumption, export treatment and system losses.

How is solar payback calculated?

Simple payback divides the project investment by estimated annual savings. A complete financial analysis should include maintenance, financing and future changes.

Off-Grid Solar Questions

What is an off-grid solar system?

It is a system designed to supply electricity without relying on a utility connection.

What equipment does an off-grid system need?

Most systems require solar panels, an inverter, batteries, protection equipment, monitoring and usually generator backup.

Can I live completely off-grid with solar?

Yes, when the system is correctly sized and the household manages energy responsibly.

Does an off-grid home need a generator?

A generator is strongly recommended for prolonged cloudy weather, unusually heavy loads, maintenance and emergencies.

How many days of battery storage does an off-grid home need?

It depends on climate, generator availability, critical loads, budget and the customer’s tolerance for energy management.

Why is an off-grid system more expensive?

It must provide energy when the utility is unavailable, requiring more batteries, controls, backup generation and careful engineering.

Can an off-grid system run several air conditioners?

Yes, but multiple air conditioners require a large solar array, substantial battery capacity and strong inverter output.

What happens during several cloudy days?

Battery reserves fall and a generator may be needed to charge the batteries and support loads.

Can an off-grid system be expanded later?

Yes, when the original system is designed with compatible inverter, battery, wiring and panel expansion capacity.

What is the biggest off-grid mistake?

Undersizing the system while expecting unlimited appliance use. Accurate load planning is essential.

Generator Integration Questions

Can any generator connect to a hybrid inverter?

No. Voltage, frequency, waveform, grounding, neutral configuration and power must be compatible.

Can a small generator charge a large battery bank?

It may charge slowly, but charging current must be limited so the generator is not overloaded.

Can the generator start automatically?

Some generators and inverters support automatic-start controls. Compatible dry contacts, wiring and programming are required.

Why does my inverter reject generator power?

Generator voltage or frequency may be outside acceptable limits, or the waveform, grounding or inverter settings may be incompatible.

Can solar reduce generator fuel use?

Yes. Solar can supply daytime loads and charge batteries, reducing generator runtime.

Should a generator connect directly to the house and inverter?

Not without properly designed transfer and isolation equipment. Unsafe connections can backfeed circuits and damage equipment.

Hurricane and Severe-Weather Questions

Are solar panels safe during hurricanes?

Solar arrays can be designed for high winds, but no system is immune to extreme wind, structural failure or flying debris.

Should solar panels be removed before a hurricane?

Properly installed permanent arrays are not normally removed for every storm. Temporary or poorly attached systems require special evaluation.

How should batteries be prepared before a hurricane?

Charge them fully, verify backup operation, reduce unnecessary loads and protect equipment from flooding and water intrusion.

Should the generator be tested before a storm?

Yes. Test operation, fuel, oil, charging and transfer behavior before the storm arrives.

What should I do if panels are damaged after a storm?

Stay away from damaged wiring, turn off equipment only when it is safe, photograph visible damage and request professional inspection.

Can flooded batteries or inverters be turned back on?

No. Flooded electrical equipment should remain de-energized until professionally inspected.

Does hurricane-rated mean hurricane-proof?

No. Engineering reduces risk but cannot guarantee survival in every possible storm or debris event.

Are solar patio covers more vulnerable to wind?

They can experience significant uplift and must be engineered as permanent structural systems with adequate foundations and bracing.

Commercial Solar Questions

Can a restaurant operate entirely on solar?

It may offset much of its annual energy use, but complete off-grid or outage operation requires detailed analysis of refrigeration, ventilation, cooling and cooking equipment.

Can solar protect restaurant refrigeration?

Yes. Refrigeration is a common critical commercial backup load. Compressor starting and total runtime must be calculated.

Can a hotel use solar for every guest room?

Yes, with sufficient array capacity. Battery backup for every room and air conditioner may require a much larger investment.

Can a business install solar in phases?

Yes. Phased installation can begin producing savings earlier, but Phase 1 should be designed around the final completed system.

Can Phase 1 savings help pay for later phases?

Yes, in principle. Actual timing depends on verified savings, project price, energy use and the customer’s cash-flow plan.

Can commercial solar work with three-phase electricity?

Yes, when the selected inverter architecture matches the voltage and phase configuration.

Can batteries reduce business interruption?

Yes. Batteries can keep selected refrigeration, communications, payment systems, security and lighting operational.

Can solar reduce commercial demand charges?

It may reduce demand when production coincides with the property’s peak. Accurate interval data is needed to estimate results.

Is commercial solar priced per watt?

Price per watt is one comparison tool, but batteries, structural work, electrical upgrades and three-phase equipment must be evaluated separately.

Does commercial solar require maintenance?

Yes. Monitoring, inspections, cleaning, corrosion checks and electrical maintenance protect long-term production.

Solar Installation Questions

How long does solar installation take?

Installation time depends on system size, roof conditions, electrical upgrades, structural work, equipment availability and property access.

What information is needed for a solar quote?

Recent CFE bills, property location, roof photographs, electrical-panel photographs, major loads, backup priorities and future plans.

Is a site visit required?

A preliminary estimate may be prepared remotely, but final design generally requires verification of the property and electrical conditions.

Does installation include racking?

It should be clearly listed in the proposal. Never assume that panel pricing automatically includes mounting hardware.

Does installation include conduit and wiring?

The proposal should identify included wiring, conduit, breakers, disconnects and any allowances or exclusions.

Does installation include electrical-panel upgrades?

Not automatically. Main-panel, subpanel, transformer or service upgrades should be listed separately when required.

What is system commissioning?

Commissioning includes testing wiring, programming equipment, verifying charging, confirming backup operation and checking monitoring.

Should every circuit be labeled?

Important breakers, disconnects, power sources and backup circuits should be clearly labeled for operation and service.

Should the customer receive system instructions?

Yes. Customers should understand normal operation, shutdown, monitoring, battery reserve and generator procedures.

Solar Pricing and Payment Questions

Why do solar quotes vary so much?

Quotes may include different panel counts, inverter capacity, batteries, racking, electrical work, structural work, warranties and installation quality.

Is the cheapest quote the best solar deal?

Usually not automatically. An undersized or incomplete system can cost more over time than a correctly designed project.

What should be included in a solar proposal?

Equipment models, quantities, installation scope, exclusions, warranties, payment terms, project price and expected performance.

Why are equipment and labor separated?

Separating them makes the payment structure clearer and identifies when equipment will be ordered and installation will begin.

Why is equipment paid before ordering?

Solar equipment often must be purchased and delivered specifically for the customer’s project.

Can a project be divided into three phases?

Yes. Each phase can include its own panels, batteries, equipment and labor while working toward one final design.

What is cost per watt?

It is the total project price divided by the solar-array wattage. It is most useful when comparing projects with a similar scope.

Should batteries be included in cost-per-watt comparisons?

Batteries make the comparison less precise because battery storage is measured in kilowatt-hours, not solar-panel watts.

Are permits included in the package price?

Not automatically. Permit, engineering and utility costs should be clearly identified in the proposal.

Can solar pricing change after the quote?

Pricing may change if equipment costs, exchange rates, taxes, site conditions or project scope change. The written proposal should state how long pricing remains valid.

Warranty and Maintenance Questions

What warranties come with a solar system?

Coverage may include panel product and performance warranties, inverter warranties, battery warranties and installer workmanship coverage.

Does a 25-year panel warranty cover everything?

No. Performance, product, labor, shipping and storm damage may be treated differently.

Does a battery warranty guarantee full capacity for ten years?

Not necessarily. Battery warranties may allow capacity decline and include cycle, temperature or throughput limitations.

Who handles warranty claims?

The process may involve the installer, distributor and manufacturer. The written warranty documents should explain the procedure.

Does a manufacturer’s warranty include installation labor?

Not always. Replacement equipment and labor may be covered separately.

How often should a solar system be inspected?

Inspection frequency depends on coastal exposure, storms, dust, system size and operating importance. Monitoring should be reviewed regularly.

How do I know whether my system is underperforming?

Compare monitoring with previous periods, weather conditions, expected seasonal output and CFE consumption.

What maintenance do batteries need?

Keep them clean, dry, within the proper temperature range and connected to correctly configured equipment. Review alarms and communication status.

What maintenance does an inverter need?

Keep ventilation clear, protect it from water and excessive heat, monitor alarms and inspect wiring and connections professionally.

Should solar systems be inspected after a hurricane?

Yes, especially when there was extreme wind, flooding, debris impact or visible structural damage.

Solar Troubleshooting Questions

Why is my solar system producing zero power?

Possible causes include nighttime conditions, open disconnects, inverter faults, grid failure, damaged wiring, communication errors or equipment shutdown.

Why is production lower than yesterday?

Weather, heat, clouds, shade, dust, consumption and equipment behavior change daily. Compare longer periods before assuming a defect.

Why is one panel producing less than the others?

Shade, dirt, damage, orientation, connector problems or microinverter faults may cause lower production.

Why is the battery not charging?

Possible causes include low solar production, charging schedules, communication failure, battery protection, settings or wiring faults.

Why does the battery stop at a certain percentage?

Reserve settings, charging limits, battery calibration, temperature or BMS protection may limit the displayed state of charge.

Why does the inverter switch to CFE while the battery still has energy?

Backup reserve, discharge schedules, battery-current limits or operating mode may cause the inverter to use the grid early.

Why is monitoring offline?

Internet loss, Wi-Fi changes, gateway power, communication wiring or server issues may interrupt monitoring.

Does offline monitoring mean the solar system stopped working?

Not necessarily. The power system may continue operating while the monitoring connection is offline.

Why does a breaker keep tripping?

Possible causes include overload, short circuit, ground fault, damaged equipment, incorrect breaker size or loose connections. Repeated tripping requires professional diagnosis.

Should I install a larger breaker to stop tripping?

No. A larger breaker can create a fire hazard when the wiring and equipment are not rated for it.

Why does the system shut down when an air conditioner starts?

Required Pump Information

Voltage
Horsepower
Running current
Starting current
Pumping depth
Required gallons or liters per day

Case Study 20: Home Solar with EV Charging

A homeowner wants to add an electric vehicle without causing a major increase in CFE expense.

Illustrative Driving Requirement

Assume the vehicle uses 18 kWh per 100 kilometers and travels 50 kilometers per day.

18 kWh ÷ 100 km × 50 km = 9 kWh per day

Approximate Solar Requirement

Using a simplified 4 kWh of useful daily energy per installed kilowatt:

9 kWh ÷ 4 = approximately 2.25 kW of additional solar

Four 615-watt panels provide:

4 × 615 watts = 2.46 kW DC

Best Charging Strategy

Charge during solar-production hours
Use adjustable charging current
Avoid charging from emergency batteries
Schedule charging when other large loads are low

Illustrative Solar Savings Comparison

Property type	Illustrative annual electricity expense	Illustrative reduction	Illustrative gross annual savings
Small home	36,000 MXN	70%	25,200 MXN
Family home	72,000 MXN	75%	54,000 MXN
Luxury villa	150,000 MXN	80%	120,000 MXN
Vacation rental	96,000 MXN	70%	67,200 MXN
Restaurant	240,000 MXN	75%	180,000 MXN
Boutique hotel	420,000 MXN	65%	273,000 MXN
Remote ranch generator costs	96,000 MXN	70%	67,200 MXN

These figures are simplified examples. Actual customer savings require current CFE bills, tariff analysis, site modeling and verified load data.

Illustrative Simple Payback Examples

Simple payback divides total project cost by estimated annual savings.

Residential Example

Project cost: 400,000 MXN
Estimated annual savings: 80,000 MXN

400,000 ÷ 80,000 = 5-year simple payback

Commercial Example

Project cost: 900,000 MXN
Estimated annual savings: 180,000 MXN

900,000 ÷ 180,000 = 5-year simple payback

Generator-Replacement Example

Project cost: 500,000 MXN
Estimated annual fuel and maintenance savings: 100,000 MXN

500,000 ÷ 100,000 = 5-year simple payback

What Simple Payback Does Not Include

Financing charges
Maintenance
Battery replacement
Future CFE price changes
Taxes
Insurance
Property-value changes
Avoided outage losses

Lessons from These Solar Case Studies

1. Solar Works Best When It Matches the Load

A system should be designed around when and how the property uses electricity.

2. Efficiency Can Reduce System Cost

Efficient air conditioners, pumps, refrigeration and lighting can reduce the required solar and battery capacity.

3. Batteries Should Be Sized for a Clear Purpose

Essential backup, overnight cooling and commercial continuity require different storage capacity.

4. Large Projects Can Be Installed in Phases

Phased projects work best when the first phase is designed for the final system.

5. Direct Solar Use Usually Has Strong Value

Running pumps, cooling and business equipment during sunlight reduces the amount of energy that must be stored.

6. Outage Protection Has Financial Value

Protecting food, guests, communications, security and business operations may be worth more than the direct electricity savings alone.

Solar Case Study and ROI Frequently Asked Questions

Are these real customer guarantees?

No. They are educational examples showing how solar projects may be analyzed. Actual results require customer-specific information.

Can every home save 70% or more?

No. Savings depend on system size, consumption, tariff, roof conditions, weather and customer behavior.

Can solar completely power a restaurant?

It may offset most annual energy use, but complete outage or off-grid operation requires detailed analysis of every major load.

Can Phase 1 savings pay for Phase 2?

Savings can be reserved toward later phases, but the exact timing depends on verified results and the project price.

Why are batteries not always the fastest ROI?

Batteries add backup and energy-control value but also add cost and conversion losses.

What usually provides the fastest solar payback?

Properties with high daytime energy use, high CFE expense, little shade and efficient equipment often have strong payback potential.

Can generator fuel savings be included in ROI?

Yes. Fuel, oil, maintenance and generator replacement can be included when those costs are documented.

Can avoided business losses be included?

Yes, but they should be identified separately from direct electricity savings.

How accurate is a solar ROI estimate?

Accuracy improves with twelve months of bills, interval load data, accurate site modeling and clearly defined assumptions.

Yes, when enough clear information is provided. Final design may still require site verification.

What is the biggest mistake solar buyers make?

Choosing only by the lowest price without comparing equipment, battery capacity, installation scope and long-term support.

Should I buy solar or batteries first?

The answer depends on whether the priority is bill reduction, emergency backup or off-grid operation. Many hybrid projects install both as one coordinated system.

Can I start small and expand later?

Yes, when the inverter, battery platform, wiring, racking and electrical distribution are designed for expansion.

Should I install more panels or more batteries?

More panels increase energy production. More batteries increase stored energy. The correct choice depends on the current system and customer goals.

Can solar remove my dependence on CFE?

It can reduce dependence substantially. Complete independence requires enough solar, batteries and backup generation for all operating conditions.

What is the best solar system for Los Cabos?

The best system is the one correctly matched to the property’s consumption, electrical service, backup needs, climate exposure and budget.

Why is local support important?

Solar systems may need monitoring help, troubleshooting, storm inspection, battery expansion and future repairs.

Package Cost per Watt Examples

Installed price per watt is calculated by dividing the package price by the solar-array wattage.

Package	Price	Array size	Package price per watt
Package 1	$9,995	4,920 watts	Approximately $2.03 per watt
Package 2	$19,995	9,840 watts	Approximately $2.03 per watt
Package 3	$29,995	14,760 watts	Approximately $2.03 per watt

These package calculations include battery storage and hybrid equipment. They should not be compared directly with solar-only price-per-watt figures.

Battery capacity is measured in kilowatt-hours. Cost per solar watt does not show how much energy the batteries can store.

Continue to Part 14: Solar Warranty, Financing and Customer Protection Center

Part 14 will explain panel, inverter, battery and workmanship warranties, warranty exclusions, customer documentation, financing disclosures, payment protection, change orders, project completion, ownership, maintenance obligations and what customers should verify before signing.

Solar Warranty, Financing and Customer Protection Center

A professional solar project should protect the customer with clear equipment specifications, written payment terms, warranty information, project milestones and a complete installation scope.

Solar panels, inverters, batteries, racking and electrical equipment may each have separate warranty terms. The installer may also provide a workmanship warranty covering qualifying installation-related issues.

Customers should understand the difference between a manufacturer warranty and an installer workmanship warranty. These are not the same protection and may have different claim procedures, exclusions and coverage periods.

Financing should also be reviewed carefully. A low monthly payment does not automatically mean a low total project cost. Interest, dealer fees, origination fees, prepayment terms and payment duration can materially change the total amount paid.

Customer protection rule: Never rely on verbal promises. Equipment, pricing, labor, warranties, exclusions, financing and payment terms should be documented in writing.

Understanding Solar Warranties

A complete solar system may include several separate warranties.

Solar Panel Product Warranty

Covers qualifying defects in panel materials or manufacturing under the manufacturer’s written terms.

Solar Panel Performance Warranty

Describes the expected minimum panel output over a stated period.

Inverter Warranty

Covers qualifying inverter defects according to the manufacturer’s written warranty.

Battery Warranty

May cover qualifying defects and specified remaining capacity, cycles or energy throughput.

Racking Warranty

Covers qualifying defects in rails, attachments, clamps or other mounting components under the manufacturer’s terms.

Workmanship Warranty

Covers qualifying installation workmanship according to the written agreement issued by the installer.

Solar Panel Product Warranty

A solar panel product warranty generally addresses defects in materials or manufacturing.

Possible Covered Conditions

Qualifying frame defects
Qualifying junction-box defects

Other conditions listed by the manufacturer

Conditions Commonly Excluded

Impact damage
Walking on panels
Flying debris
Improper installation
Unauthorized repair or modification
Fire or flooding
Lightning damage
Animal damage
Failure of the roof or supporting structure
Use outside manufacturer requirements

The exact manufacturer warranty document controls coverage. General website language does not replace the written warranty supplied with the selected panel model.

Solar Panel Performance Warranty

A performance warranty describes expected panel output over time.

Solar panels normally lose a small amount of production capacity as they age. A performance warranty may state that the panel should retain at least a specified percentage of its original rated output after a stated number of years.

Performance Warranty Does Not Automatically Mean

The panel will produce the same energy every year
The entire system is guaranteed to meet a specific CFE savings level
Labor is included in the claim
Shipping is included
Storm damage is covered
The panel will be replaced immediately

Factors That Affect Actual Panel Production

Shade
Panel temperature
Dust and salt
Orientation
Inverter performance
Wiring losses
Weather
System downtime

Solar Inverter Warranty

The inverter is one of the most important electronic components in the solar system.

Physical damage
Improper wiring
Unauthorized opening of the battery enclosure
Failure to follow manufacturer instructions

Battery Capacity Decline

Battery capacity normally declines over time. A battery warranty does not necessarily guarantee that the battery will retain 100% of its original storage capacity for the entire warranty period.

Installation Workmanship Warranty

A workmanship warranty covers qualifying defects related to the installer’s work, not every possible equipment failure.

Possible Workmanship Coverage

Qualifying loose electrical connections
Qualifying conduit installation defects
Improperly secured wiring
Qualifying roof penetration issues caused by the installation
Incorrect equipment programming performed by the installer
Other covered workmanship issues listed in the contract

Possible Workmanship Exclusions

Manufacturer equipment failure

Solar Financing Overview

Financing may allow a customer to install solar without paying the entire project price at once.

Financing is not automatically cheaper than paying cash. The total cost depends on interest, loan length, fees and payment terms.

Possible Financing Methods

Personal loan
Home-improvement loan
Bank financing
Credit-card payment
Property-backed financing
Commercial equipment financing
Phased cash installation
Customer-arranged financing

Cabo Solar Experts should only advertise financing as available when a current financing program has been confirmed. Approval is never guaranteed.

Understanding the True Cost of Solar Financing

Customers should compare the cash price with the total financed price.

Financing Costs May Include

Interest
Dealer fee
Origination fee
Application fee
Late-payment fee
Insurance
Closing costs
Prepayment penalty
Currency-conversion costs

Example Financing Comparison

Option	Illustrative amount	Important consideration
Cash price	$19,995 USD	Lowest total price when no financing costs apply
Financed amount	$19,995 USD plus financing costs	Total paid depends on rate, term and fees
Long-term financing	Lower monthly payment	May create a much higher total cost

This example does not represent a current financing offer.

Questions to Ask Before Financing Solar

What is the cash price?
What is the financed project price?
What is the annual interest rate?
What is the total amount paid over the loan?
Are there dealer or origination fees?
Is there a prepayment penalty?
Is the rate fixed or variable?
Is collateral required?
What happens if the property is sold?
Who owns the solar equipment?
When does the first payment begin?
What happens if installation is delayed?

Phased Installation as an Alternative to Financing

Customers who do not want long-term financing may build the system in planned phases.

Phase 1

Install the main hybrid inverter, initial battery storage and the first group of solar panels.

Phase 2

Add more solar panels or batteries after the customer has saved additional money or confirmed energy savings.

Phase 3

Complete the final planned array and storage capacity.

Benefits of Phased Installation

Reduced initial cash requirement
No long-term lender obligation
Earlier energy production
Ability to confirm performance before expansion
Flexibility when energy needs change

Phased Installation Risk

Phase 1 must be designed for the final system. A poorly planned first phase may require equipment replacement later.

Customer Payment Protection

A payment schedule should correspond to clear project milestones.

Cabo Solar Experts Standard Payment Structure

Payment stage	Purpose
100% equipment payment	Purchase and reserve the approved equipment
100% labor payment before installation	Schedule the installation crew and complete project labor

Alternative staged payments may be used only when stated in the written proposal.

Solar Installation Standards and Quality-Control Guide

A solar system is only as reliable as the design, structural mounting, electrical workmanship, equipment programming and final testing behind it.

Premium solar panels and batteries cannot correct poor workmanship. Loose connections, undersized conductors, weak mounting, exposed wiring, poor equipment placement and incomplete commissioning can reduce production, shorten equipment life and create serious safety problems.

Cabo Solar Experts evaluates the complete installation rather than treating solar panels, inverters and batteries as separate products.

Every project should be designed for the actual roof, structure, electrical service, wind exposure, property loads, equipment ratings and customer backup goals.

Quality-control rule: A solar installation is not complete until the structure, wiring, protection, programming, monitoring and backup operation have been inspected and tested.

Pre-Installation Property Review

The installation process should begin with verification of the property information used to prepare the proposal.

Property Information to Confirm

Exact installation address
Property access
Roof type
Roof age and condition
Structural framing
Available panel area
Shade conditions
Electrical-service voltage
Single-phase, split-phase or three-phase configuration
Main-panel rating
Backup circuits
Battery location
Inverter location
Generator information
Conduit routes
Future expansion plans

Documents to Review

Signed proposal
Equipment list
Roof measurements
Electrical photographs
Equipment data sheets
Manufacturer installation instructions
Structural drawings when required
Utility or interconnection documentation when applicable

A remote estimate should not be treated as final engineering when site conditions have not been verified.

Roof Condition and Preparation

Solar panels may remain on a roof for decades. Installing them over a failing or damaged roof is a bad decision.

Roof Conditions to Inspect

Cracks
Water leaks
Loose tiles
Corroded metal
Weak framing
Damaged waterproofing
Previous unsealed penetrations
Standing water
Blocked drainage
Concrete deterioration

Before Solar Installation

Necessary roof repairs should be completed before the solar racking is installed.

If the roof is near the end of its useful life, replacing or repairing it before solar installation may prevent expensive panel removal later.

Roof Responsibility

The proposal should state whether roof repair, waterproofing or structural reinforcement is included or excluded.

Structural Review and Load Considerations

Solar panels add weight and wind forces to the roof or support structure.

Structural suitability should not be assumed from appearance alone.

Structural Factors

Panel weight
Racking weight
Existing roof loads
Attachment spacing
Roof framing
Concrete condition
Steel condition
Wood condition
Wind uplift
Panel height above the roof
Edge and corner exposure
Future maintenance access

When Engineering May Be Required

Large commercial arrays
Solar carports
Second-floor patio covers
Long structural spans
High wind exposure
Weak or unusual roofs

Nearby buildings and wind channels

Hurricane-Conscious Installation Practices

Use appropriate structural attachments
Connect attachments to suitable structural material
Use approved panel clamps
Maintain proper clamp locations
Avoid excessive rail overhang
Secure exposed wiring
Protect roof penetrations
Use corrosion-resistant hardware where appropriate
Inspect the array after severe storms

No solar system can be described honestly as hurricane-proof. Good engineering and workmanship reduce risk but cannot eliminate every extreme-weather hazard.

Roof Attachments and Waterproofing

Roof attachments must secure the solar array without creating avoidable leaks or structural damage.

Attachment Requirements

Match the roof type
Connect to suitable structure
Use compatible fasteners
Use appropriate flashing or sealing method
Maintain required spacing

Why Is My Solar System Producing Less Electricity?

Low production does not always mean equipment has failed. Weather, temperature, shade, dirt and seasonal sun position affect output.

Common Causes of Low Solar Production

Cloudy weather
High panel temperature
Dust or salt buildup
New tree or building shade
One failed solar string
One failed microinverter
Loose or damaged connector
Open DC breaker or disconnect

How to Evaluate Production

Compare similar weather days.
Do not compare a cloudy day with a clear day.
Compare the same season.
Summer and winter production may differ.
Review the full day.
One low reading at a specific moment does not prove a fault.
Check the production curve.
Sudden gaps or flat sections may indicate shutdown or shading.
Compare individual devices.
Module-level monitoring may identify one underperforming panel.

Why Is My Solar System Producing Zero Power?

Normal Reasons

Nighttime
Very low sunlight
Scheduled shutdown
Utility outage on a grid-tied system without backup

Solar Maintenance and Repair Frequently Asked Questions

How do I know whether my solar system needs service?

Warning signs include unexpected production loss, repeated fault codes, battery problems, breaker trips, unusual heat, offline devices or visible damage.

Does low production always mean something is broken?

No. Clouds, heat, seasonal sunlight, shade and dirt can reduce output. Compare similar conditions before concluding that equipment failed.

Should I reset an inverter fault?

Document the code first. One approved reset may be reasonable under manufacturer instructions, but repeated faults require diagnosis.

Why does my battery run out before morning?

The nighttime load may be larger than the usable stored energy. Air conditioning and electric heating can drain batteries quickly.

Why is one battery not working?

Possible causes include an open breaker, communication fault, incorrect address, BMS alarm or internal battery problem.

Why does my inverter reject generator power?

Voltage, frequency, waveform, grounding or charging-current settings may be outside acceptable limits.

Does offline monitoring mean the system stopped?

Not necessarily. The inverter may continue operating while the internet or monitoring gateway is offline.

How often should solar panels be cleaned?

Clean them when dust, salt or debris causes meaningful production loss. Coastal and dusty properties may need more frequent cleaning.

Should I pressure-wash solar panels?

High-pressure cleaning can damage seals, wiring or glass and should generally be avoided.

Should solar be inspected after a hurricane?

Yes. High winds, debris and water can damage racking, wiring, enclosures and batteries.

Can flooded solar equipment be reused?

It must remain de-energized until professionally evaluated. Flood damage may make equipment unsafe or unrepairable.

Why does my breaker keep tripping?

Possible causes include overload, short circuit, ground fault, loose wiring or failed equipment. Do not install a larger breaker without proper engineering.

Can Cabo Solar Experts repair systems installed by another company?

Service may be available depending on the equipment, documentation, location, access and condition of the existing installation.

What should I send before requesting service?

Send the location, equipment models, fault codes, photographs, monitoring screenshots and a description of the problem.

Is maintenance covered by the equipment warranty?

Routine inspection, cleaning and maintenance are usually separate from manufacturer defect coverage.

Continue to Part 17: Solar Design Calculations and System-Sizing Center

Part 17 will explain how to calculate daily kilowatt-hour consumption, solar-panel quantity, inverter power, battery runtime, air-conditioning loads, generator size, voltage drop, system losses, commercial demand and phased system expansion using practical examples.

Solar Design Calculations and System-Sizing Center

Correct solar design begins with actual energy consumption, peak power, equipment starting requirements, battery runtime goals and available installation space.

A property can have a low average daily energy requirement and still need a large inverter because several high-power appliances operate at the same time.

The opposite can also happen. A property may have modest peak power but consume a large amount of energy over many hours, requiring more solar panels and battery storage.

Core design rule: Solar panels are sized in watts and kilowatts. Energy consumption and battery capacity are measured in kilowatt-hours. Inverter capacity is based primarily on simultaneous power and starting surge.

Information Required Before Sizing a Solar System

Do not size a system from a guess or from one appliance label alone.

Watts, Kilowatts and Kilowatt-Hours

Measurement	What it means	Example
Watt	Basic unit of electrical power	A light may use 10 watts
Kilowatt	1,000 watts of power	A mini-split may draw 1.2 kW while operating
Kilowatt-hour	Energy used or produced over time	1.2 kW operating for 5 hours uses 6 kWh

Power in kilowatts × operating hours = energy in kilowatt-hours

How to Calculate Daily Energy Consumption

Multiply each appliance’s operating power by its estimated daily hours, then add every appliance together.

Appliance power in kW × hours used per day = daily kWh

Small Off-Grid Home Example

Load	Average power	Hours per day	Daily energy
Refrigerator	0.15 kW average	24	3.60 kWh
Lights	0.10 kW	6	0.60 kWh
Internet and electronics	0.12 kW	12	1.44 kWh
Water pump	0.75 kW	1	0.75 kWh
Mini-split	0.90 kW average	6	5.40 kWh
Total	—	—	11.79 kWh per day

Appliance nameplate power may differ from actual average consumption. Variable-speed equipment should be measured whenever possible.

Calculate Daily Consumption from a CFE Bill

Divide total billing-period consumption by the number of days in that billing period.

Billing-period kWh ÷ billing days = average daily kWh

Example: 2,700 kWh Over 60 Days

2,700 ÷ 60 = 45 kWh per day

Example: 6,000 kWh Over 60 Days

6,000 ÷ 60 = 100 kWh per day

Average daily consumption does not show the highest simultaneous demand. Inverter sizing requires a separate peak-load calculation.

Calculate Annual Electricity Consumption

Add all CFE billing-period kilowatt-hours covering approximately twelve months.

Illustrative Annual Consumption

Billing period	Consumption
Period 1	1,800 kWh
Period 2	2,100 kWh
Period 3	2,700 kWh
Period 4	3,200 kWh
Period 5	2,900 kWh
Period 6	2,000 kWh
Annual total	14,700 kWh

14,700 kWh ÷ 365 = approximately 40.27 kWh per day

Preliminary Solar Array Sizing

Divide daily energy consumption by the estimated useful daily energy produced by each installed kilowatt of solar capacity.

Daily kWh requirement ÷ useful daily kWh per installed kW = preliminary solar-array size

Example: 40 kWh per Day

Using an illustrative assumption of four useful daily kilowatt-hours per installed kilowatt:

40 ÷ 4 = 10 kW preliminary array

Example: 100 kWh per Day

100 ÷ 4 = 25 kW preliminary array

The useful-energy assumption should account for temperature, inverter losses, wiring, shading, orientation, soiling and seasonal variation.

Solar System Loss Factors

Solar-panel nameplate wattage does not equal the energy delivered to the building under every condition.

Common Losses

Panel temperature
Inverter conversion
Wiring resistance
Dust and salt
Module mismatch
Shade
Panel orientation
Battery charging and discharging
Clipping
System downtime

Illustrative Derating Example

A 10 kW array using five effective solar hours would produce 50 kWh before system losses.

10 kW × 5 hours = 50 kWh before losses

Applying an illustrative 80% overall factor:

50 × 0.80 = 40 kWh estimated useful daily energy

Calculate the Number of Solar Panels

Required array watts ÷ panel wattage = required panel quantity

Using JA Solar 615W Panels

Target array	Calculation	Practical panel count	Actual capacity
5 kW	5,000 ÷ 615 = 8.13	8 or 9 panels	4.92 or 5.535 kW
10 kW	10,000 ÷ 615 = 16.26	16 or 17 panels	9.84 or 10.455 kW
15 kW	15,000 ÷ 615 = 24.39	24 or 25 panels	14.76 or 15.375 kW
20 kW	20,000 ÷ 615 = 32.52	32 or 33 panels	19.68 or 20.295 kW
25 kW	25,000 ÷ 615 = 40.65	41 panels	25.215 kW

The final panel count must also match inverter voltage, MPPT current, roof geometry and string design.

Common JA Solar 615W Array Sizes

Panel count	Total array size	Common project type
4 panels	2.46 kW	Small expansion or pump offset
8 panels	4.92 kW	Essential Backup package
12 panels	7.38 kW	Small home or commercial phase
16 panels	9.84 kW	Whole-Home Hybrid package
20 panels	12.30 kW	Large home or office
24 panels	14.76 kW	Energy Independence package
30 panels	18.45 kW	Large villa or commercial project
36 panels	22.14 kW	Restaurant or phased commercial system
48 panels	29.52 kW	Hotel, warehouse or commercial carport

How to Size a Solar Inverter

Inverter size is based on simultaneous electrical demand, motor-starting surge, service voltage and system architecture.

Step 1: List Simultaneous Loads

Add the loads that may operate at the same time.

Load	Operating power
Two mini-splits	2.40 kW total
Refrigerator and freezer	0.50 kW total average
Water pump	1.00 kW
Lights and outlets	0.70 kW
Kitchen appliances	1.50 kW
Total operating load	6.10 kW

This example may require an inverter larger than 6.1 kW to provide operating margin and support starting surges.

Step 2: Account for Surge Loads

Motors and compressors may draw substantially more power during startup than during normal operation.

Step 3: Include Future Loads

Additional mini-splits
Pool equipment
Electric cooking
EV charging
Guest house
Workshop tools

Illustrative Inverter Capacity Classes

Inverter class	Common application	Important limitation
6 kW	Small homes and essential backup	Limited operation of multiple heavy loads
8 kW	Medium homes and vacation rentals	Large air conditioners still require load management
12 kW	Large homes and smaller commercial projects	Not unlimited whole-property power
Parallel inverters	Large residential, commercial or off-grid systems	Models and firmware must support parallel operation
Three-phase inverter system	Commercial motors and three-phase services	Must match service voltage and phase arrangement

How to Size Battery Capacity

Battery storage is based on the energy required during the period when solar or utility power is unavailable.

Average backup load in kW × required hours = required usable battery energy

Example: Essential Backup

Assume the average backup load is 500 watts for 8 hours.

0.50 kW × 8 hours = 4 kWh usable energy

After reserve and conversion losses, one 5.12 kWh battery may be near the minimum starting point.

Example: Nighttime Cooling

Assume one mini-split and household essentials average 1.5 kW for 8 hours.

1.5 kW × 8 = 12 kWh usable energy

This would generally require more than two nominal 5.12 kWh batteries after accounting for reserve and losses.

Adjust Battery Size for Reserve and Efficiency

The full battery nameplate capacity may not be available for normal use.

Required usable energy ÷ usable battery fraction ÷ system efficiency = approximate required nameplate capacity

Illustrative Example

Required usable energy: 10 kWh
Planned usable fraction: 90%
Illustrative conversion efficiency: 90%

10 ÷ 0.90 ÷ 0.90 = approximately 12.35 kWh nameplate capacity

Three 5.12 kWh batteries provide 15.36 kWh of nameplate storage and may provide an appropriate design margin, subject to battery power limits.

5.12 kWh Battery Capacity Examples

Battery quantity	Nameplate storage	General application
1 battery	5.12 kWh	Short essential backup
2 batteries	10.24 kWh	Longer essential or partial-home backup
3 batteries	15.36 kWh	Selected overnight cooling or larger backup
4 batteries	20.48 kWh	Extended residential backup
6 batteries	30.72 kWh	Large home, restaurant or off-grid operation
8 batteries	40.96 kWh	Large commercial or extended off-grid storage

Battery energy capacity and battery power output are separate limits. A battery bank may contain enough energy but still lack the instantaneous discharge power required for a large load.

Battery Power and Discharge Capacity

Batteries must supply both enough stored energy and enough instantaneous power.

Energy Question

How many kilowatt-hours must the battery provide?

Power Question

How many kilowatts must the battery supply at one time?

Example

A battery bank may store 20 kWh, but if its permitted continuous output is only 5 kW, it cannot reliably operate an 8 kW load.

Loads Requiring High Battery Power

Large air conditioners
Water pumps
Pool equipment
Compressors
Electric cooking
Commercial refrigeration
Welders

Air-Conditioning Energy Calculation

Air-conditioning consumption depends on actual average compressor power, not only the cooling-capacity label.

Illustrative Mini-Split Example

Average operating power: 1.1 kW
Operating time: 10 hours

1.1 × 10 = 11 kWh per day

Three Mini-Splits

If three units average 0.9 kW each for 8 hours:

3 × 0.9 × 8 = 21.6 kWh per day

Factors That Increase Cooling Consumption

Poor insulation
Open doors and windows
Very low thermostat setting
Oversized rooms
Dirty filters
Old equipment
Direct afternoon sun
High occupancy

Battery Sizing for Overnight Air Conditioning

Overnight cooling is one of the fastest ways to increase battery cost.

One Mini-Split Example

Mini-split average: 1.0 kW
Other household loads: 0.4 kW
Total average load: 1.4 kW
Desired runtime: 9 hours

1.4 × 9 = 12.6 kWh usable energy

After reserve and losses, a practical design may require approximately 15–18 kWh of nameplate storage.

Two Mini-Splits Example

Two mini-splits and essential household loads may average 2.5 kW.

2.5 × 9 = 22.5 kWh usable energy

This may require approximately 25–30 kWh or more of nameplate battery storage, depending on real operating conditions.

Water Pump and Motor Sizing

Pumps require calculations for both operating power and starting surge.

Information Needed

Voltage
Phase
Horsepower
Running current
Starting current
Pump depth
Daily operating hours
Water volume required

Illustrative Energy Example

A 1.5 kW pump operating for 3 hours:

1.5 × 3 = 4.5 kWh per day

Better Solar Strategy

Pump water during strong sunlight and store water in a tank. This can be less expensive than storing the same amount of energy in batteries.

Pool Pump Energy Calculation

Single-Speed Pump Example

Pump power: 1.5 kW
Runtime: 8 hours

1.5 × 8 = 12 kWh per day

Variable-Speed Pump Example

Average power: 0.65 kW
Runtime: 8 hours

0.65 × 8 = 5.2 kWh per day

The simplified difference is:

12 − 5.2 = 6.8 kWh saved per day

Efficiency improvements can reduce the number of panels and batteries required.

Restaurant Load Calculation Example

Restaurant load	Average power	Hours	Daily energy
Walk-in refrigeration	2.0 kW average	24	48.0 kWh
Freezers and smaller refrigerators	1.0 kW average	24	24.0 kWh
Air conditioning	4.0 kW average	8	32.0 kWh
Lighting	0.8 kW	10	8.0 kWh
Ventilation and miscellaneous	1.2 kW	8	9.6 kWh
Total	—	—	121.6 kWh per day

This simplified example excludes electric cooking loads. Actual restaurant consumption should be confirmed from bills and equipment data.

Preliminary Solar Size

Using four useful daily kilowatt-hours per installed kilowatt:

121.6 ÷ 4 = approximately 30.4 kW of solar

Approximate 615W Panel Count

30,400 ÷ 615 = approximately 50 panels

Hotel Energy Calculation Method

Hotels should be divided into energy categories rather than treated as one undifferentiated load.

Guest-Room Cooling Example

30 occupied rooms × 0.9 kW average cooling × 10 hours:

30 × 0.9 × 10 = 270 kWh per day

This illustrates why hotel solar is commonly phased and why efficiency improvements should be evaluated before adding large battery banks.

How to Size a Backup Generator

Generator sizing must include property loads, battery charging and motor-starting surge.

Generator Load Components

Loads operating directly from the generator
Battery charger demand
Motor-starting surge
Generator derating in heat or altitude
Desired operating margin

Illustrative Example

Property loads: 4 kW
Battery charging: 3 kW
Operating total: 7 kW

A generator should not normally be selected to operate continuously at its absolute maximum rating.

Generator nameplate rating, continuous rating and surge rating may be different. Confirm the manufacturer’s real continuous output.

Generator Battery-Charging Calculation

Inverter battery-charging power should be limited so the generator can also support active property loads.

Example

Generator continuous capacity: 8 kW
Property operating loads: 3 kW
Remaining theoretical power: 5 kW

Charging should be set below the theoretical maximum to preserve operating margin and account for conversion losses.

Why Charging Current May Need Reduction

Small generator
Unstable generator voltage
Other loads operating
Hot weather
Long generator wiring
Generator overload alarms

Voltage-Drop Planning

Long conductor runs create voltage loss. Excessive voltage drop can reduce equipment performance and create grid or generator faults.

Voltage-Drop Factors

Conductor length
Current
Wire size
Copper or aluminum
AC or DC voltage
Operating temperature
Connections and terminals

General Principle

Higher current and longer distance require larger conductors to maintain acceptable voltage.

Final conductor sizing must use the applicable electrical rules, manufacturer instructions and actual installation conditions.

Solar String Voltage Calculation

Panels connected in series add voltage.

Panel voltage × number of panels in series = string voltage

Illustrative Example

Assume each panel has an open-circuit voltage of 50 volts.

8 panels × 50 volts = 400 volts open circuit before temperature adjustment

Cold conditions can increase panel voltage. The adjusted maximum must remain below the inverter’s maximum DC input voltage.

Current in Parallel Strings

Strings connected in parallel add current rather than voltage.

Never design a string from an assumed panel voltage. Use the exact panel data sheet and inverter limits.

Calculate Required Roof or Ground Space

Panel dimensions, spacing, setbacks, access and obstructions determine the actual installation area.

Basic Area Formula

Panel length × panel width × panel quantity = basic panel surface area

Additional space is required for:

Panel gaps
Roof edges
Maintenance access
Drainage
Shade separation
Fire or service pathways
Roof equipment
Row spacing on tilted systems

Why Large 615W Panels Require Careful Layout

High-output panels can reduce panel quantity but are physically large. Roof dimensions and lifting access must be confirmed before ordering.

How to Size a Solar System Installed in Phases

Design the final completed system first, then divide it into practical phases.

Final-System Questions

What is the completed panel count?
What is the completed array size?
What inverter capacity is required?
What battery capacity is required?
How many MPPT inputs are needed?
What conductor sizes support the final system?
How much roof or structural space is needed?

Illustrative 36-Panel Project

Phase	New panels	Cumulative panels	Cumulative solar capacity
Phase 1	12	12	7.38 kW
Phase 2	12	24	14.76 kW
Phase 3	12	36	22.14 kW

Phase 1 Infrastructure May Include

Final-size or expandable inverter architecture
Conduit for all future panels
Electrical panels sized for later phases
Roof layout preserving expansion space
Compatible battery platform
Monitoring configured for expansion

Calculate Estimated Solar Offset

Estimated useful annual solar energy ÷ annual property consumption × 100 = estimated solar offset percentage

Example

Annual consumption: 20,000 kWh
Estimated useful solar energy: 15,000 kWh

15,000 ÷ 20,000 × 100 = 75% estimated annual offset

Why Financial Savings May Differ from Energy Offset

Different tariff blocks
Fixed charges
Demand charges
Export-credit rules
Battery losses
Time of energy use

Solar Savings and Simple Payback Calculation

Annual Expense

Average CFE bill × number of annual billing periods = annual electricity expense

Estimated Annual Savings

Annual electricity expense × estimated bill-reduction percentage = estimated gross annual savings

Simple Payback

Total project price ÷ estimated annual savings = simple payback period

Example

Annual expense: 120,000 MXN
Estimated reduction: 75%
Project price: 450,000 MXN

120,000 × 75% = 90,000 MXN estimated annual savings

450,000 ÷ 90,000 = 5-year simple payback

Calculate Installed Price per Watt

Total project price ÷ solar-array watts = project price per watt

Package 1 Example

$9,995 ÷ 4,920 watts = approximately $2.03 per watt

Package 2 Example

$19,995 ÷ 9,840 watts = approximately $2.03 per watt

Package 3 Example

$29,995 ÷ 14,760 watts = approximately $2.03 per watt

These package calculations include battery storage and hybrid equipment. Comparing them directly with solar-only projects can be misleading.

Commercial Peak-Demand Calculation

Commercial demand is based on the highest simultaneous power requirement during the applicable measurement interval.

Illustrative Restaurant Peak

Simultaneous equipment	Power
Air conditioning	8 kW
Refrigeration	5 kW
Ventilation	2 kW
Lighting and outlets	2 kW
Kitchen electrical loads	6 kW
Estimated simultaneous demand	23 kW

A restaurant consuming 100 kWh per day may still require more than a 20 kW inverter if heavy equipment operates at the same time.

Reduce Loads Before Buying More Solar

The cheapest kilowatt-hour is often the one the property no longer wastes.

Efficiency Improvements

Replace old mini-splits
Improve insulation
Seal doors and windows
Use LED lighting
Replace single-speed pool pumps
Repair refrigeration seals
Schedule pumps during daylight
Use efficient water heating
Control vacation-rental thermostats
Eliminate unnecessary standby loads

Illustrative Savings

Reducing daily consumption from 50 kWh to 40 kWh lowers required solar production by 10 kWh per day.

10 kWh ÷ 4 useful daily kWh per installed kW = approximately 2.5 kW less solar required

That equals roughly four 615W panels.

Common Solar Sizing Mistakes

Sizing from the peso bill instead of kilowatt-hours
Using only one unusually low billing period
Ignoring summer air conditioning
Ignoring motor-starting surge
Confusing battery kWh with inverter kW
Assuming all battery capacity is usable
Ignoring future loads
Ignoring shade
Ignoring generator limitations
Using panel nameplate output as guaranteed production
Failing to design Phase 1 for future expansion
Ignoring service voltage and phase
Ignoring inverter MPPT limits
Ignoring battery discharge-power limits

Oversizing wastes money. Undersizing creates disappointment. The goal is a system matched to the property and the customer’s actual priorities.

Solar Sizing Frequently Asked Questions

How many solar panels does my house need?

Divide the property’s daily energy requirement by expected useful solar production, then convert the required array size into the selected panel wattage.

Can you size solar from one CFE bill?

One bill provides a preliminary estimate, but twelve months of bills produces a stronger annual design.

How do I calculate average daily consumption?

Divide the billing-period kilowatt-hours by the number of days in the billing period.

How many 615W panels make 10 kW?

Sixteen panels equal 9.84 kW and seventeen panels equal 10.455 kW.

How many batteries do I need?

Multiply average backup power by required runtime, then adjust for reserve, conversion losses and battery power limits.

Can one 5.12 kWh battery run an air conditioner all night?

Usually not for a full night when household loads are included. Actual runtime depends on the mini-split’s measured average power.

What is more important, battery kWh or inverter kW?

Both matter. Battery kWh determines stored energy, while inverter kW determines how much power can be supplied at one time.

Why can a large battery still fail to start a pump?

The battery or inverter may not have enough instantaneous surge power, even if the battery stores enough total energy.

How large should my generator be?

Add active property loads, battery-charging demand, starting surge and operating margin.

Can I install fewer panels now and add more later?

Yes, when inverter inputs, roof layout, wiring and racking are designed for the completed system.

Why should pool pumps run during daylight?

Daytime operation allows the pump to use solar energy directly instead of consuming battery energy at night.

How do I calculate solar price per watt?

Divide the total project price by the solar-array wattage. Battery packages should not be compared directly with solar-only projects.

What is the biggest mistake in off-grid sizing?

Underestimating nighttime energy use while expecting unlimited air conditioning, pumping and appliance operation.

Continue to Part 18: Residential Solar Systems by Home Size and Lifestyle

Part 18 will organize solar recommendations for small homes, family houses, luxury villas, condominiums, vacation rentals, pool homes, retirement properties, hurricane-backup homes and fully off-grid residences throughout Los Cabos and Baja California Sur.

Residential Solar Systems by Home Size and Lifestyle

The correct residential solar system depends on much more than the number of bedrooms. Air conditioning, pools, water pumps, electric cooking, occupancy, rental use, outage protection and future expansion can change the design substantially.

A two-bedroom home occupied full time may use more electricity than a four-bedroom vacation property that is occupied only a few weeks each year. That is why Cabo Solar Experts reviews actual electricity consumption, appliance loads and customer priorities before recommending equipment.

The home categories below provide practical starting points for properties throughout Cabo San Lucas, San José del Cabo, Los Cabos, the East Cape, Todos Santos, La Paz and other Baja California Sur communities.

Residential design rule: Bedroom count helps describe the property, but actual kilowatt-hour consumption and simultaneous appliance demand determine the system size.

Residential Solar Starting-Point Comparison

Property type	Planning solar range	Typical 615W panel range	Planning battery range	Common inverter class
Casita or tiny home	2.46–4.92 kW	4–8 panels	5.12–10.24 kWh	3–6 kW
Small one- or two-bedroom home	4.92–7.38 kW	8–12 panels	5.12–15.36 kWh	6 kW
Condo or townhome	2.46–7.38 kW	4–12 panels	5.12–10.24 kWh	3–8 kW
Retirement home	4.92–9.84 kW	8–16 panels	10.24–20.48 kWh	6–8 kW
Medium family home	9.84–14.76 kW	16–24 panels	10.24–25.60 kWh	8–12 kW
Large villa	14.76–29.52 kW	24–48 panels	15.36–40.96 kWh or more	12 kW or parallel inverters

These are preliminary planning ranges. Actual equipment selection depends on measured consumption, roof space, service voltage, battery output and backup requirements.

Solar for Small Homes in Los Cabos

A small one- or two-bedroom home can often begin with an expandable hybrid system using eight to twelve high-output solar panels.

Small homes are excellent candidates for solar when the major loads are efficient and the customer controls nighttime air-conditioning use.

Common Small-Home Electrical Loads

One refrigerator
One or two mini-split air conditioners
LED lighting
Television
Internet or Starlink
Small water-pressure pump
Washing machine
Microwave
Normal outlets and device charging

Recommended Starting Solar Range

8 × JA Solar 615W panels for a 4.92 kW array
12 × JA Solar 615W panels for a 7.38 kW array
6 kW-class hybrid inverter
One to three 5.12 kWh batteries
Essential-load or partial-home backup panel
Remote monitoring

Illustrative Daily Production

4.92 kW × 5 effective solar hours × 0.80 = approximately 19.68 kWh per day

7.38 kW × 5 effective solar hours × 0.80 = approximately 29.52 kWh per day

A small efficient home may use between approximately 10 and 30 kWh per day, but air conditioning can push consumption much higher.

Recommended Backup Priorities

Refrigerator
Internet
Security
Lighting
Selected outlets
One efficient mini-split
Water-pressure pump

Best Expansion Path

Start with the hybrid inverter, essential-load panel and one battery. Add batteries when longer nighttime operation is needed. Add panels when daytime consumption increases.

One small battery should not be sold as unlimited overnight air-conditioning backup. Actual runtime must be calculated from the mini-split’s measured consumption.

Solar for Tiny Homes and Compact Off-Grid Houses

Tiny homes can operate efficiently on solar, but limited roof space and heavy air-conditioning loads can still create design problems.

A compact house does not automatically mean low energy use. Electric cooking, electric water heating and continuous cooling can consume more energy than the home’s physical size suggests.

Typical Tiny-Home Loads

Compact refrigerator
One mini-split
LED lights
Internet
Laptop or television
Small water pump
Induction cooktop or microwave
Optional washing machine

Utility-Connected Tiny-Home Starting Point

4 to 8 panels
2.46 to 4.92 kW solar capacity
3 to 6 kW inverter
One 5.12 kWh battery for essential backup

Off-Grid Tiny-Home Starting Point

8 to 12 panels
4.92 to 7.38 kW array
6 kW hybrid off-grid inverter
10.24 to 15.36 kWh battery storage
Small generator for prolonged cloudy conditions

Energy-Saving Design Decisions

Use propane or solar thermal water heating when appropriate
Use an efficient inverter mini-split
Improve roof and wall insulation
Shade west-facing windows
Run washing and pumping during sunlight
Avoid high-power resistance heating

Roof-Space Problem

A tiny home may not have enough roof area for the required array. Ground mounts, solar carports and patio covers can create additional panel space.

Solar for Casitas and Guest Houses

Casitas may be powered independently or connected to the main home’s solar and battery system.

Independent Casita System

An independent system may be useful when the casita is far from the main electrical service or has separate rental use.

4 to 8 panels
3 to 6 kW inverter
One or two batteries
Separate monitoring
Separate critical-load control

Casita Connected to the Main System

A larger central hybrid system may serve both buildings when conductor distance, voltage drop and total demand are acceptable.

Information Needed

Distance from the main house
Casita panel voltage
Air-conditioner size
Water-heating method
Cooking equipment
Rental occupancy
Whether backup is required

Common Mistake

Adding a casita without expanding the inverter, batteries or solar array can overload the original home system.

Solar for Condominiums in Cabo San Lucas and San José del Cabo

Condo solar can work, but roof ownership, HOA rules, shared electrical systems and limited equipment space must be addressed first.

Common Condo Challenges

Shared roof
HOA approval
Limited roof allocation
Shared utility meters
Limited battery space

Individual Condo Starting Range

4 to 12 panels
2.46 to 7.38 kW solar capacity
3 to 8 kW inverter
5.12 to 10.24 kWh battery storage

Common Backup Loads

Refrigerator
Internet
Lights
Security
Television
Selected outlets
One mini-split when properly sized

Documents to Obtain Before Installation

HOA approval
Roof-use authorization
Architectural requirements
Electrical-room access approval
Structural approval when required
Insurance requirements

Do not order condo solar equipment until roof rights and HOA approval are clear in writing.

Solar for Townhomes and Attached Residences

Townhomes may have individually owned roof sections, shared walls, common electrical services or HOA-controlled exterior surfaces.

Townhome Solar Starting Range

6 to 12 panels
3.69 to 7.38 kW solar capacity
6 kW hybrid inverter
One or two batteries
Essential or partial-home backup

Design Questions

Who owns the roof?
Is the electrical meter individual?
Where can the inverter be mounted?
Where can batteries be installed?
Will conduit cross common property?
Are there architectural restrictions?
Can the roof support the array?

Best Use of Limited Roof Space

High-output panels can maximize solar capacity when the available roof area is limited.

Solar for Apartments and Small Multifamily Properties

Apartment solar design depends on whether the property has individual meters, one master meter or landlord-paid common utilities.

Common Multifamily Solar Models

Common-Area Solar

Supplies gates, exterior lighting, pumps, offices and shared equipment.

Master-Meter Solar

Offsets electricity used by the entire building when one primary meter is used.

Individual-Unit Systems

Separate systems serve independently metered apartments when roof allocation allows.

Typical Common Loads

Water pumps
Exterior lighting
Security systems
Entry gates
Pool equipment
Laundry rooms
Management office
Internet equipment

Possible Starting Range

12 to 48 panels
7.38 to 29.52 kW solar capacity
Commercial or multiple hybrid inverters
Battery backup for critical common systems

Why Multifamily Projects Need Better Planning

Ownership, billing, access, tenant consumption and maintenance responsibilities must be clearly defined.

Solar for Retirement Homes in Baja California Sur

Retirement-home solar should prioritize reliability, simple operation, comfortable cooling and dependable outage protection.

Retired homeowners may spend more time at home during the day than working households. That means daytime cooling and appliance use can align well with solar production.

Common Retirement-Home Priorities

Stable monthly expenses
Reliable refrigeration
Internet and communications
Comfortable air conditioning
Medical-device backup when applicable
Simple monitoring
Low generator dependence
Hurricane readiness

Recommended Starting Range

8 to 16 panels
4.92 to 9.84 kW solar capacity
6 to 8 kW hybrid inverter
10.24 to 20.48 kWh battery storage
Essential or whole-home backup design
Generator connection when practical

Why More Battery May Be Appropriate

Customers who depend on medical refrigeration, mobility equipment, communications or continuous cooling may need longer battery runtime than a standard bill-reduction customer.

Medical Equipment Planning

Medical devices must be evaluated individually. The system should not be described as medical backup without confirming voltage, power, runtime, surge and safety requirements.

Simple Operation Recommendations

Clearly labeled backup circuits
Simple written shutdown instructions
Remote monitoring support
Automatic transfer when compatible
High battery reserve during hurricane season
Annual system inspection

One-Bedroom Home Solar Example

Illustrative total	13.0 kWh per day

Possible Solar Design

8 panels
4.92 kW solar capacity
6 kW hybrid inverter
One battery for short backup
Two batteries for stronger overnight support

Illustrative Production

Approximately 19.68 kWh per day under the simplified planning assumption

This may be enough to offset the illustrative daily use, but seasonal weather and actual air-conditioning consumption must be considered.

Two-Bedroom Home Solar Example

Illustrative Loads

Two mini-splits
Refrigerator
Washing machine
Internet and television
Water-pressure pump
Microwave and kitchen appliances
Indoor and outdoor lighting

Illustrative Daily Consumption

A moderately efficient two-bedroom home may use approximately 18–35 kWh per day depending on cooling.

Roof Layout Must Allow for

Panel dimensions
Panel spacing
Roof edges
Drainage
Maintenance access
Water tanks
Mini-split condensers
Satellite dishes
Parapet-wall shade
Future expansion

Alternative Panel Locations

Solar patio cover
Solar carport
Ground mount
Detached garage
Equipment structure

Small-Home CFE Savings Example

Assume a small home spends 7,500 MXN every sixty days.

7,500 MXN × 6 billing periods = 45,000 MXN annual electricity expense

If the solar system reduces annual grid purchases by approximately 70%:

45,000 MXN × 70% = 31,500 MXN estimated gross annual savings

What Can Reduce the Savings?

Customer increases air-conditioning use
New appliances are added
Panels become shaded or dirty
Battery losses are higher than expected
CFE billing rules or tariffs change
The system is undersized

Savings percentages are not guarantees. Final estimates require actual billing and consumption information.

Hurricane Backup for Small and Retirement Homes

A properly designed smaller system can protect essential services during hurricane-related outages without attempting to power every appliance.

Priority Loads

Refrigeration
Water pump
Internet and phone charging
Security
Emergency lighting
One cooling room
Medical refrigeration when required

Storm Preparation

Charge batteries to full capacity
Increase the backup reserve
Test the generator
Confirm critical circuits
Turn off nonessential loads
Review monitoring access
Inspect panels and visible racking

One-Room Cooling Strategy

During a long outage, cooling one well-insulated bedroom requires much less energy than cooling the entire home.

Expansion Planning for Small Residential Systems

A smaller starting system should not trap the customer in equipment that must be replaced when the home expands.

Future Expansion Questions

Will another bedroom be added?
Will another mini-split be installed?
Will a pool be added?
Will an EV charger be installed?
Will a casita be built?
Will the customer move off-grid later?
Will more battery runtime be required?

Design for Expansion

Select an inverter with available solar-input capacity
Reserve roof space
Install larger conduit where practical
Use an expandable battery platform
Leave electrical-panel capacity
Document the intended final design

Continue to Part 18B: Family Homes, Luxury Villas and Vacation Rentals

Part 18B will cover medium family homes, large homes, beachfront villas, luxury estates, vacation properties, Airbnb rentals, second homes, pool homes and properties with multiple air conditioners.

Solar for Family Homes, Luxury Villas and Vacation Rentals

Medium and large homes in Los Cabos often have several mini-split air conditioners, pool equipment, water pumps, guest bedrooms, outdoor living areas and higher nighttime energy use.

These homes usually require more than a basic solar package. The system must be designed around the number of occupants, cooling schedule, pool equipment, property-management needs, backup priorities and future expansion.

Vacation rentals and luxury villas create an additional challenge because guests may use electricity differently from the owner. Air conditioners may remain on with doors open, pool equipment may operate longer than necessary and large appliances may run at the same time.

Large-home design rule: Do not size a luxury or rental property only from the number of bedrooms. Use actual CFE history, measured electrical loads and realistic guest behavior.

Family Home and Luxury Villa Starting-Point Comparison

Property type	Planning solar range	615W panel range	Planning battery range	Common inverter architecture
Three-bedroom family home	7.38–12.30 kW	12–20 panels	10.24–20.48 kWh	8–12 kW hybrid inverter
Four-bedroom family home	9.84–14.76 kW	16–24 panels	15.36–25.60 kWh	12 kW hybrid inverter
Large luxury villa	14.76–29.52 kW	24–48 panels	20.48–40.96 kWh or more	12 kW or parallel hybrid inverters
Beachfront villa	14.76–29.52 kW	24–48 panels	20.48–40.96 kWh or more	Hybrid system with corrosion-conscious installation
Vacation rental or Airbnb	9.84–22.14 kW	16–36 panels	10.24–30.72 kWh	Hybrid system with remote monitoring
Second home with limited occupancy	4.92–12.30 kW	8–20 panels	5.12–15.36 kWh	6–12 kW hybrid inverter
Large pool home	12.30–22.14 kW	20–36 panels	15.36–30.72 kWh	12 kW or parallel hybrid system

Final equipment depends on actual consumption, electrical service, battery-output requirements, generator integration, roof space and the customer’s backup expectations.

Solar for a Three-Bedroom Family Home

A three-bedroom family home often requires a larger system than customers expect because air conditioning, refrigeration, laundry, water pumping and pool equipment may operate every day.

Common Electrical Loads

Three or four mini-split air conditioners
Refrigerator and freezer
Washing machine and dryer
Dishwasher
Microwave and kitchen appliances
Water-pressure pump
Pool pump
Internet, security and electronics
Indoor and outdoor lighting

Planning Solar Range

12 panels for a 7.38 kW array
16 panels for a 9.84 kW array
20 panels for a 12.30 kW array
8 to 12 kW hybrid inverter
10.24 to 20.48 kWh battery storage

Illustrative Daily Production

9.84 kW × 5 effective solar hours × 0.80 = approximately 39.36 kWh per day

12.30 kW × 5 effective solar hours × 0.80 = approximately 49.20 kWh per day

Recommended Backup Priorities

Refrigerator and freezer
Internet and security
Water-pressure pump
Lighting and outlets
One or two efficient mini-splits
Selected kitchen circuits

Loads to Manage During an Outage

Electric dryer
Pool heater
Electric water heater
Multiple air conditioners
Electric oven
EV charger

Solar for a Four-Bedroom Family Home

A four-bedroom home may require a 12 kW inverter or parallel system when several air conditioners, pumps and kitchen loads operate simultaneously.

Recommended Planning Range

16 to 24 JA Solar 615W panels
9.84 to 14.76 kW total solar capacity
12 kW hybrid inverter
15.36 to 25.60 kWh battery storage
Critical-load or whole-home distribution
Generator integration when practical

Illustrative Energy Use

A four-bedroom home may consume approximately 40 to 80 kWh per day, depending on cooling, occupancy, pools and electric heating.

Why Battery Size Can Increase Quickly

Four mini-splits averaging 0.9 kW each create 3.6 kW of cooling demand before refrigeration, lighting, pumps and other loads are added.

3.6 kW × 8 nighttime hours = 28.8 kWh for cooling alone

This is why a basic two-battery package cannot honestly be described as full overnight whole-home cooling for a large house.

Solar for Luxury Villas in Los Cabos

Luxury villas in Palmilla, Pedregal, Puerto Los Cabos, Cabo del Sol and other premium communities often combine heavy cooling loads with pools, spas, guest suites, water pumps, outdoor kitchens and extensive lighting.

Common Luxury-Villa Loads

Six or more mini-split or central air-conditioning zones
Multiple refrigerators and freezers
Pool and spa pumps
Pool heat pump or electric heating equipment

12 kW hybrid inverter or parallel inverter system
20.48 to 40.96 kWh battery storage or more
Generator integration
Load-management controls
Whole-home surge protection
Advanced remote monitoring

Whole-Home Backup Does Not Mean Unlimited Power

Whole-home backup means most circuits are connected to the hybrid system. It does not mean every load can operate simultaneously without limits.

Recommended Outage Strategy

Operate selected cooling zones
Delay pool heating
Reduce spa operation
Pause EV charging
Use generator support for extended outages
Preserve battery reserve for nighttime

Luxury Villa Solar Production Examples

Panel count	Array capacity	Illustrative useful daily production	Common application
24 panels	14.76 kW	Approximately 59.04 kWh	Large home with moderate cooling
30 panels	18.45 kW	Approximately 73.80 kWh	Villa with several cooling zones
36 panels	22.14 kW	Approximately 88.56 kWh	Large villa or rental property
48 panels	29.52 kW	Approximately 118.08 kWh	Luxury estate or heavy-load residence

Production examples use five effective solar hours and an 80% planning factor. Actual production varies by season, temperature, orientation, shade, dirt and system availability.

Solar for Beachfront Homes and Oceanfront Villas

Beachfront properties require extra attention to corrosion, wind exposure, equipment placement and storm preparation.

Coastal Design Problems

Salt-air corrosion
Wind-driven rain
Hurricane uplift
Flying debris
Direct sunlight on inverters and batteries
High humidity
Limited protected equipment space
Remote service access

Recommended Coastal Installation Practices

Use corrosion-resistant mounting hardware where appropriate
Protect steel structures with suitable coatings

Internet and security backup
Automatic fault notifications
Generator integration
Property-manager access

Planning System Range

16 to 36 panels
9.84 to 22.14 kW solar capacity
8 to 12 kW inverter or parallel architecture
10.24 to 30.72 kWh battery storage

Best Backup Priorities

Refrigeration
Internet
Security cameras
Entry systems
Emergency lighting
Selected bedroom air conditioning
Water-pressure pump

Airbnb Energy Controls and Remote Management

Solar alone does not stop guests from wasting electricity. Rental properties benefit from energy-management controls.

Recommended Controls

Smart thermostats
Maximum cooling limits
Door and window sensors
Occupancy-based temperature control
Pool-pump timers
EV charger access control
Remote water-heater control
Automated high-usage alerts

Example Thermostat Policy

A property may limit cooling to a reasonable temperature and automatically adjust the system when exterior doors remain open.

Property-Manager Dashboard

The owner or manager should be able to review:

Current solar production
Battery state of charge
Grid power use
Active fault codes
Unusual overnight consumption
System status during an outage

Financial Value of Solar for Vacation Rentals

Vacation-rental solar may provide value through lower CFE bills, reduced outage losses and improved guest experience.

Illustrative Annual CFE Expense

Assume the rental spends 18,000 MXN every sixty days.

18,000 MXN × 6 = 108,000 MXN annual electricity expense

At an illustrative 70% reduction:

108,000 MXN × 70% = 75,600 MXN estimated gross annual savings

Additional Potential Value

Fewer guest refunds
Reduced food spoilage
Fewer emergency property-manager visits
Better guest reviews
More reliable internet and security
Stronger sustainability marketing

Avoided refunds and improved reviews should be presented separately from direct electricity savings because they are harder to predict.

Solar for Second Homes and Seasonal Properties

A second home may have low annual occupancy but still require dependable refrigeration, security, internet and storm protection when the owner is away.

Common Second-Home Priorities

Keep refrigerator operating
Maintain security cameras
Maintain internet
Prevent battery discharge while vacant
Monitor outages remotely
Protect water systems
Prepare the property before arrival

Recommended Starting Range

8 to 20 panels
4.92 to 12.30 kW solar capacity
6 to 12 kW hybrid inverter
5.12 to 15.36 kWh battery storage
Remote monitoring
Smart thermostat and security integration

Why a Smaller Battery May Be Enough

When the property is vacant, backup may only need to support refrigeration, security and communications rather than whole-home comfort.

Arrival Preparation

Remote controls may allow the owner or manager to begin cooling selected rooms before the owner arrives.

Solar for Homes with Swimming Pools and Spas

Pool equipment can become one of the largest predictable electrical loads in a Los Cabos home.

Common Pool Loads

Circulation pump
Water-feature pump
Spa pump
Pool lights
Saltwater chlorinator
Electric heat pump
Control system

Single-Speed Pool Pump Example

1.5 kW × 8 hours = 12 kWh per day

Variable-Speed Pump Example

0.65 kW × 8 hours = 5.2 kWh per day

Recommended Pool Strategy

Use a variable-speed pump
Run circulation during peak solar hours
Use a pool cover when heating
Operate the heat pump during daylight
Keep pool heating outside emergency backup circuits
Monitor pool energy separately when practical

Solar for Pool Heat Pumps

A pool heat pump may use several kilowatts for many hours. It must be treated as a major seasonal load.

Illustrative Pool Heat-Pump Example

Heat-pump power: 5 kW
Operating time: 6 hours

5 kW × 6 hours = 30 kWh per day

Approximate Solar Capacity Required

Using four useful daily kilowatt-hours per installed kilowatt:

30 kWh ÷ 4 = approximately 7.5 kW of additional solar

That is approximately twelve or thirteen 615-watt panels.

Pool heating can dominate the CFE bill. It should be calculated separately from normal household electricity.

Solar for Homes with Multiple Air Conditioners

Cooling is usually the largest variable residential load in Baja California Sur.

Five Mini-Split Example

Assume five mini-splits average 0.9 kW each and operate for eight hours.

5 × 0.9 kW × 8 hours = 36 kWh per day

Household loads may add another 15 to 30 kWh per day.

Potential Total Consumption

36 kWh cooling + 24 kWh household loads = approximately 60 kWh per day

Preliminary Solar Size

60 ÷ 4 = approximately 15 kW solar capacity

Approximately twenty-four or twenty-five 615-watt panels may be required, depending on actual operating conditions.

Battery Reality

Running five air conditioners all night may require a very large and expensive battery bank. Most customers receive better value by backing up selected cooling zones.

Generator Integration for Large Homes and Villas

A generator can support large homes during extended outages and help recharge batteries after several low-production days.

Generator Functions

Support large household loads
Recharge batteries
Provide backup during extended storms
Reduce the required battery-bank size
Protect guest comfort

Generator Integration Requirements

Correct voltage
Correct frequency
Adequate continuous power
Proper neutral and grounding arrangement
Safe transfer controls
Compatible automatic-start controls when included
Charging-current limits

Recommended Operating Strategy

Use solar and batteries for normal operation. Use the generator for long outages, heavy loads or battery recovery rather than running it continuously.

Hurricane Backup for Luxury and Rental Properties

Pre-Storm Preparation

Charge all batteries fully
Increase emergency reserve
Test the generator
Confirm fuel supply
Inspect visible racking and panels
Secure outdoor furniture and debris
Confirm internet and monitoring
Review critical-load circuits
Contact the property manager

During an Outage

Cool selected bedrooms only
Turn off pool heating

Limit electric cooking
Preserve battery energy for nighttime
Run the generator when battery state requires it

After the Storm

Inspect for panel movement
Check for broken glass
Check equipment for water intrusion
Review fault history
Do not touch damaged wiring
Schedule professional inspection when damage is suspected

Luxury Home CFE Savings Example

Assume a villa spends 30,000 MXN every sixty days.

30,000 MXN × 6 = 180,000 MXN annual electricity expense

At an illustrative 75% reduction:

180,000 MXN × 75% = 135,000 MXN estimated gross annual savings

What Can Change the Result?

Higher guest occupancy
Additional air-conditioning use
Pool-heating use
EV charging
New guest-house loads
System downtime
Tariff or billing changes

Continue to Part 18C: Restaurants, Hotels, Farms, Offices and Commercial Buildings

Part 18C will cover restaurant refrigeration, hotel guest loads, farm pumps, ranch power, warehouses, offices, retail stores, medical clinics, multifamily buildings and phased commercial solar systems.

Solar for Restaurants, Hotels, Farms, Offices and Commercial Buildings

Commercial solar systems must be designed around business operating hours, refrigeration, motors, air conditioning, three-phase equipment, peak demand, backup priorities and the financial cost of losing power.

Commercial properties in Los Cabos and Baja California Sur often use most of their electricity during daylight hours. That can make solar especially valuable because energy is consumed while the panels are producing it.

Battery backup can also protect refrigeration, payment systems, internet, security, water pumps and other critical equipment during CFE outages.

Commercial design rule: Do not size a business system from the monthly peso amount alone. Review kilowatt-hours, operating schedules, peak simultaneous demand, motor starting current, service voltage and the cost of business interruption.

Commercial Solar Starting-Point Comparison

Property type	Planning solar range	615W panel range	Planning battery range	Common design priority

Water Storage Instead of Battery Storage

Pumping water during daylight and storing it in a tank can be cheaper than storing all pumping energy in batteries.

Illustrative Pump Example

Pump power: 3 kW
Daily operation: 5 hours

3 kW × 5 hours = 15 kWh per day

Preliminary Solar Capacity

15 kWh ÷ 4 useful daily kWh per installed kW = approximately 3.75 kW of solar

Motor surge, pump-controller requirements and seasonal water demand must still be verified.

15.36 to 61.44 kWh battery storage or more
Generator integration
Load-management controls
Remote monitoring through Starlink or internet

Best Off-Grid Rule

Heavy tools and pumps should operate when solar production is strong or when the generator is available.

Ranch Generator Fuel Savings Example

Assume generator fuel and maintenance cost 12,000 MXN per month.

12,000 MXN × 12 = 144,000 MXN annual generator expense

If solar reduces generator-related expense by 70%:

144,000 MXN × 70% = 100,800 MXN estimated annual savings

Fuel savings should be based on actual fuel use, maintenance records and generator runtime.

Many restaurants, hotels, pumps, workshops and commercial buildings use three-phase electrical service.

Three-Phase Information Required

Line-to-line voltage
Line-to-neutral voltage
Service configuration
Main-breaker rating
Transformer information
Phase loading
Motor voltage
Generator phase configuration

Possible Three-Phase Architectures

Continue to Part 18D: Off-Grid Homes, Generators, Water Pumps, EV Charging and Hurricane Backup

Part 18D will cover complete off-grid homes, generator-supported systems, water pumping, desalination, electric vehicles, hurricane preparation, remote East Cape properties and long-duration battery backup.

Off-Grid Homes, Remote Properties and Long-Duration Backup

Off-grid solar systems must produce enough electricity for daily use, store enough energy for nighttime operation and include a backup strategy for cloudy weather, equipment failure and unusually heavy loads.

Remote properties throughout the East Cape, Cabo Pulmo, Vinorama, Los Barriles, La Ribera, Todos Santos, Mulegé, Bahía Concepción and other areas of Baja California Sur often depend on solar panels, lithium batteries and generators instead of reliable utility service.

Off-grid design is less forgiving than normal grid-connected solar. When a utility-connected system produces less than expected, CFE may supply the difference. In a fully off-grid system, the customer must reduce loads, start the generator or accept a shutdown.

Off-grid design rule: Size the system for realistic daily consumption, nighttime demand, motor-starting power, seasonal conditions and several days of imperfect weather. Do not design from the best sunny day of the year.

Core Components of an Off-Grid Solar System

Solar Array

Produces daily electricity and must be large enough to operate loads while also recharging the battery bank.

Hybrid or Off-Grid Inverter

Converts DC electricity into AC electricity and coordinates solar, batteries and generator power.

Lithium Battery Bank

Stores electricity for nighttime use, cloudy periods and temporary high-demand conditions.

Backup Generator

Supports heavy loads and recharges batteries during extended low-production periods.

Load Management

Prevents unnecessary appliances from draining batteries or overloading the inverter.

Monitoring

Shows solar production, battery charge, generator operation, consumption and system faults.

Off-Grid Solar Starting-Point Comparison

Property type	Planning solar range	615W panel range	Planning battery range	Common inverter class
Small off-grid casita	4.92–7.38 kW	8–12 panels	10.24–15.36 kWh	6 kW
Two-bedroom off-grid home	7.38–12.30 kW	12–20 panels	15.36–25.60 kWh	6–12 kW
Three- or four-bedroom off-grid home	12.30–22.14 kW	20–36 panels	25.60–40.96 kWh	12 kW or parallel inverters
Large remote villa	18.45–36.90 kW or more	30–60 panels or more	30.72–61.44 kWh or more	Parallel hybrid inverters
Ranch with pumps and workshop	12.30–49.20 kW or more	20–80 panels or more	20.48–61.44 kWh or more	Large hybrid or three-phase system
Remote hospitality property	22.14–73.80 kW or more	36–120 panels or more	40.96–102.40 kWh or more	Commercial hybrid architecture

Actual system size depends on air conditioning, pumps, water treatment, refrigeration, occupancy, generator support and desired reserve.

Two-Bedroom Off-Grid Home Example

Load	Average power	Daily operating time	Daily energy
Refrigerator	0.15 kW average	24 hours	3.60 kWh
Two mini-splits	1.60 kW average total	8 hours	12.80 kWh
Lights and outlets	0.20 kW	6 hours	1.20 kWh

Water-pressure pump	0.75 kW	1 hour	0.75 kWh
Washing and miscellaneous	1.00 kW average	1.5 hours	1.50 kWh
Illustrative total	—	—	22.25 kWh per day

Preliminary Solar Requirement

22.25 kWh ÷ 4 useful daily kWh per installed kW = approximately 5.56 kW of solar

A more conservative off-grid design may use 7.38 kW or more to recharge batteries faster and provide seasonal margin.

Possible Starting Equipment

12 × 615W panels
7.38 kW solar capacity
6 kW or larger hybrid inverter
15.36 to 20.48 kWh battery storage
Backup generator

Battery Autonomy for Off-Grid Homes

Battery autonomy describes how long the property can operate without meaningful solar production or generator support.

One Night of Backup

If nighttime loads average 1.5 kW for ten hours:

1.5 kW × 10 hours = 15 kWh usable nighttime energy

After reserve and conversion losses, approximately 18–20 kWh of nameplate battery storage may be appropriate.

Twenty-Four Hours of Autonomy

If the full property uses 25 kWh per day:

25 kWh ÷ 0.90 ÷ 0.90 = approximately 30.86 kWh nameplate capacity

Two Days of Autonomy

25 kWh × 2 days ÷ 0.90 ÷ 0.90 = approximately 61.73 kWh nameplate capacity

Large battery autonomy is expensive. A correctly integrated generator is often more economical than buying enough batteries for several cloudy days.

Generator-Supported Off-Grid Solar

A generator should be treated as a planned component, not an emergency afterthought.

Generator Functions

Recharge batteries during cloudy weather
Support large motor loads
Operate workshop equipment
Provide backup during inverter service
Reduce required battery capacity
Protect refrigeration and water systems

Generator Information Required

Continuous power rating
Surge rating
Voltage
Frequency
Single-phase or three-phase output
Fuel type
Remote-start capability
Neutral and grounding configuration
Fuel consumption

Automatic Generator Start

Compatible systems may start the generator automatically when battery state of charge reaches a programmed threshold.

Recommended Generator Testing

Test startup monthly
Run under load
Confirm battery charging
Confirm automatic start when included
Maintain oil and filters
Keep clean fuel available

Off-Grid Generator Fuel Savings Example

Assume a remote property spends 8,000 MXN per month on generator fuel and maintenance.

8,000 MXN × 12 = 96,000 MXN annual generator expense

If solar and batteries reduce generator expense by 75%:

96,000 MXN × 75% = 72,000 MXN estimated annual savings

Additional Benefits

Less generator noise
Fewer fuel-delivery trips
Reduced engine maintenance
Longer generator life
More reliable nighttime power

Solar for Well Pumps and Water Systems

Water pumping can be one of the largest off-grid loads, but it can often be scheduled during strong sunlight.

Required Pump Information

Pump horsepower
Voltage
Phase
Running current
Starting current
Well depth
Total dynamic head
Required water volume
Daily pumping hours
Storage-tank capacity

Illustrative Pump Example

Pump power: 2.2 kW
Daily operation: 4 hours

2.2 kW × 4 hours = 8.8 kWh per day

Preliminary Solar Requirement

8.8 kWh ÷ 4 useful daily kWh per installed kW = approximately 2.2 kW of solar

A practical design may use additional solar capacity to account for pump startup, weather and other property loads.

Store Water Instead of Storing All Pumping Energy

Water tanks can reduce battery cost by allowing pumps to run during daylight.

Recommended Strategy

Pump during strong sunlight.
Use direct solar production instead of battery energy.
Fill a storage tank.
Store water for evening and nighttime use.
Use a smaller pressure pump.
Supply household pressure from stored water.
Reserve batteries for essential electrical loads.
Protect refrigeration, lighting and communications.

Benefits

Smaller battery bank
Lower generator runtime
Reduced nighttime power demand
Improved water availability

Solar for Desalination and Reverse-Osmosis Systems

Desalination and reverse-osmosis equipment can create substantial electrical loads, especially when high-pressure pumps are used.

Information Required

System manufacturer and model
Production volume per hour
Feed-water type
Pump voltage
Operating power
Starting surge
Daily operating hours
Storage-tank size
Pre-treatment equipment

Illustrative Desalination Example

Average electrical demand: 3.5 kW
Operation: 5 hours per day

3.5 kW × 5 hours = 17.5 kWh per day

Preliminary Solar Requirement

17.5 kWh ÷ 4 = approximately 4.38 kW of dedicated solar capacity

Approximately eight 615-watt panels provide 4.92 kW of array capacity.

Best Operating Strategy

Produce water during strong sunlight and store it in tanks rather than operating high-pressure pumps from batteries at night.

Solar Backup for Starlink, Internet and Security Systems

Remote properties often depend on Starlink for communication, security, remote work and system monitoring.

Common Communication Loads

Starlink equipment
Wi-Fi routers
Network switches
Security cameras
Alarm systems
Gate controls
Remote sensors

Illustrative Daily Energy

A combined communications and security load averaging 150 watts for 24 hours uses:

0.15 kW × 24 = 3.6 kWh per day

These loads should be included in nighttime battery calculations because they often operate continuously.

Air Conditioning in an Off-Grid Home

Off-grid air conditioning is possible, but it must be controlled.

One Mini-Split Example

Average operating power: 0.9 kW
Daily operation: 10 hours

0.9 kW × 10 = 9 kWh per day

Three Mini-Split Example

3 × 0.9 kW × 10 hours = 27 kWh per day

Best Off-Grid Cooling Practices

Use efficient inverter mini-splits
Cool selected rooms
Improve insulation
Shade west-facing walls and windows
Pre-cool during sunlight
Use ceiling fans
Maintain clean filters
Raise thermostat settings during cloudy weather

Customers expecting every room to remain cold all night need a large solar array, large battery bank and strong generator support.

Off-Grid Refrigeration and Food Protection

Refrigeration is normally one of the highest off-grid priorities.

Recommended Practices

Use energy-efficient refrigerators
Keep door seals in good condition
Provide ventilation around compressors
Avoid placing refrigerators in extreme heat
Separate critical refrigeration circuits
Use temperature alarms
Maintain generator backup

Multiple Refrigerators and Freezers

Remote villas, ranches and hospitality properties may need separate refrigeration measurements because multiple compressors can start together.

Solar-Powered Electric Vehicle Charging

EV charging can add a large predictable electrical load to a home, hotel, office or solar carport.

Illustrative Charging Example

Charger power: 7.2 kW
Charging time: 4 hours

7.2 kW × 4 hours = 28.8 kWh per charging session

Approximate Solar Capacity

28.8 kWh ÷ 4 useful daily kWh per installed kW = approximately 7.2 kW of additional solar

That equals approximately twelve 615-watt panels.

Best Charging Strategy

Charge during daylight
Use adjustable charging current
Pause charging during outages
Prevent EV charging from draining emergency batteries
Coordinate charging with pool pumps and other heavy loads

Off-Grid EV Charging Reality

Charging an EV from an off-grid battery at night can consume more stored energy than the house uses.

Example

An EV receives 30 kWh while the house uses 20 kWh per day.

30 kWh vehicle charging + 20 kWh household use = 50 kWh total daily energy

Preliminary Solar Requirement

50 ÷ 4 = approximately 12.5 kW of solar capacity

Approximately twenty-one 615-watt panels provide 12.915 kW.

Off-grid EV charging must be included in the original system design. Adding it later can overwhelm the solar array, batteries and generator.

Common Off-Grid Solar Mistakes

Underestimating air-conditioning use
Buying too few solar panels
Buying batteries without checking discharge power
Using an undersized generator
Ignoring pump starting surge
Running heavy loads at night
Allowing batteries to reach critically low charge repeatedly
Failing to maintain generator fuel
Adding EV charging without redesigning the system
Installing equipment in direct sun or flooding areas
Failing to monitor the system
Expecting unlimited electricity

Off-grid living requires either disciplined energy use or a much larger equipment budget. There is no honest way around that.

Off-Grid System Selection Guide

Customer priority	Recommended starting strategy
Small remote casita	8–12 panels, 6 kW inverter, two or three batteries and generator
Full-time off-grid home	12–24 panels, 6–12 kW inverter, three to six batteries and generator
Multiple air conditioners	Larger array, larger battery bank and selected-zone cooling strategy
Well pumping	Daytime solar pumping with water storage
Desalination	Operate during sunlight and store finished water
Ranch workshop	Use solar for normal loads and generator support for heavy tools
EV charging	Dedicated added solar capacity and controlled daytime charging
Hurricane backup	Critical-load panel, batteries, generator and high reserve setting

Off-Grid Solar, Generator and Hurricane Backup FAQs

How many panels does an off-grid house need?

Small off-grid homes may begin with eight to twelve 615-watt panels. Larger homes with multiple air conditioners, pumps or EV charging may require twenty to sixty panels or more.

How many batteries does an off-grid home need?

Battery quantity depends on nighttime energy, desired autonomy, reserve settings and battery discharge power. Many full-time homes require three to eight battery modules or more.

Can an off-grid home operate without a generator?

It is possible with a large solar array, large battery bank and strict load management, but a generator provides valuable protection during extended cloudy conditions or equipment problems.

Can solar run a well pump?

Yes. Pump horsepower, voltage, running current, starting surge, well depth and daily water requirements must be confirmed.

Should a well pump run from batteries at night?

Daytime pumping into a storage tank is usually more efficient and economical than nighttime pumping from batteries.

Can solar operate a desalination system?

Yes. High-pressure pump power, daily water production and operating hours must be included in the solar design.

Can I charge an electric vehicle off-grid?

Yes, but EV charging may require substantial additional solar capacity. Daytime controlled charging is usually best.

Can solar run several mini-splits all night?

It can with sufficient battery capacity and inverter power, but overnight whole-home cooling requires a large and expensive system.

What should I run during strong solar production?

Pumps, laundry, desalination, pool equipment, workshop tools and EV charging should be scheduled during daylight whenever possible.

When should an off-grid generator start?

It should start before batteries reach a damaging or emergency-low state of charge, according to the programmed reserve and operating plan.

How do I prepare solar batteries for a hurricane?

Charge them fully, increase the backup reserve, test the generator, reduce unnecessary loads and confirm critical circuits.

Should I inspect solar panels after a hurricane?

Yes. Inspect for panel movement, broken glass, loose conduit, water intrusion and electrical faults from a safe location.

Can flooded batteries or inverters be turned back on?

No. Flooded electrical equipment should remain de-energized until professionally evaluated.

Is remote monitoring important for an off-grid property?

Yes. It can identify low batteries, reduced solar production, generator failure and communication problems before a total shutdown.

What is the biggest off-grid solar mistake?

Expecting unlimited air conditioning, pumping and appliance use from a small solar array and small battery bank.

How do I request an off-grid system design?

Send a complete appliance list, equipment power ratings, daily operating hours, pump information, generator details, site location and desired battery runtime.
