What Happens to Solar Panels During a Monsoon Storm?

This entry was posted in Solar Services on by .

Monsoon season officially started as of June 15. National Weather Service Phoenix office meteorologists predict that the 2022 monsoon may have above normal rainfall, according to data from the Climate Prediction Center. If you have solar panels installed on your home or are thinking about installing a solar power system, what’s the impact of monsoon storms? The good news is there’s little to worry about.

Solar Panels Undergo Rigorous Testing

The solar panels that Cool Blew Solar installs undergo extensive testing and certification and are designed and manufactured to hold up against severe weather conditions. The durability and capability of solar panels to withstand heavy rain downpours, dust storms, and strong winds has been extensively tested by Arizona’s annual summer monsoon thunderstorms.


Solar panels are built to withstand winds up to 140 miles per hour. They’re fastened to roofs with large lag bolts that prevent panels from lifting during monsoon thunderstorms. Wind will actually increase the efficiency of your solar panel system because the cooler air from monsoon storm down drafts will cool down the panels operating temperature. Cool Blew Solar’s installers have years of experience securing solar panels. Our trustworthy professionals are very familiar with the weather conditions in our area.

Rain and Dust

Rain can’t do any physical damage to your home’s solar panels as they are covered with a waterproof encapsulant. In fact, raindrops can reduce the dust, dirt, and debris that accumulates on them during the year. The massive dust storms, called haboobs, during the monsoon season won’t do any physical damage to your solar panels either, but they can reduce the panels energy output for a short period of time during the storm. After the storm subsides, spraying water from your hose is generally enough to ensure that the panel surface is clean and running at full capacity.
