Do Solar Panels Work During Baja’s Rainy Season?
If you’re considering solar power in Baja California Sur, you might wonder how solar performance during Baja weather—especially the rainy season—will affect your investment. The good news is that modern solar systems are designed to perform even when the sun isn’t shining at full strength.
Understanding Baja’s Rainy Season
In Los Cabos and surrounding areas, the rainy season typically occurs from late July to September, bringing occasional tropical storms and increased cloud cover. While these months can see less sunshine, they still offer ample daylight for solar power generation.
Do Solar Panels Work on Cloudy Days?
Yes. Solar panels generate electricity even when it’s cloudy. While their output is lower than on clear days, panels can still produce 10%–30% of their rated power under dense cloud cover—and even more under light overcast conditions.
How Weather Affects Solar System Output
| Weather Condition | Approximate Power Output |
|---|---|
| Full Sun | 100% |
| Light Clouds | 80%–90% |
| Heavy Clouds | 10%–30% |
| Rain / Storms | 10%–20% |
How Solar Systems Compensate During Rainy Periods
- Oversized Systems – We design your system to exceed your average usage, building in room for cloudy days.
- Net Metering Credits – Grid-tied users store extra power during sunny months and use those credits during cloudy ones.
- Battery Backup – For hybrid and off-grid systems, stored energy ensures uninterrupted power during storms.
Do Storms Damage Solar Panels?
Not with proper installation. At Cabo Solar Experts, we use hurricane-rated mounting systems and corrosion-resistant materials designed for Baja’s coastal and tropical conditions. Our panels are tested to withstand wind speeds of over 240 km/h.
Benefits of Rain for Solar Systems
- Natural Cleaning: Rain washes away dust and salt buildup, boosting performance afterward

Frequently Asked Questions – Solar in Baja Weather
Do I need more panels because of the rainy season?
Not necessarily. We size your system with rainy months in mind to maintain year-round performance.
Will my system stop working in storms?
If you’re grid-tied without a battery, it may shut off during an outage. Hybrid and off-grid systems keep running with stored energy.
How do I know if my system is underperforming?
We install monitoring tools so you can track performance and get alerts if output drops below expected levels.
Can solar survive a hurricane?
Yes—with the right mounts and hardware. We use hurricane-rated racking systems in vulnerable zones.
