Let’s get right to the point — yes, solar panels work in the rain, but their output can be affected.
If you’re considering a solar panel installation in NJ, you may be concerned about their energy production during rainy or cloudy weather. Since New Jersey has, on average, 117 days per year with some type of precipitation (rain, hail, snow, and sleet), it makes sense that homeowners would question the efficacy of solar panels during inclement weather. The truth is that rain itself is not detrimental to solar energy systems. Clouds associated with rain, however, can have an impact on the output of the solar system.
Remember that even on rainy days, some rays of sun are breaking through the clouds to reach the panels. And if you live in an area where sunshine is bountiful, then the power that your solar system produces during sunny periods of the day can offset the energy required to sustain a comfortable home when your system is not producing as much as you’d like due to rain and clouds.
Solar panels are not harmed by the rain; in fact, they’re not affected at all. Because solar panels are waterproof, rain can’t damage them. New Jersey’s average of 48 inches of rain per year, which is more than the national average of 38 inches, is actually somewhat beneficial for solar panels. This is because rain washes away dirt, grime, and debris that tend to accumulate naturally on the surface of the panels.
Clouds are the natural enemy of solar power since they can limit the solar energy output in the solar power system. A good rule of thumb is to switch essential devices to non-solar energy power through effective net metering once the clouds roll in. This ensures that you don’t run out of power despite the weather.
We’re no stranger to severe weather, including hurricanes and tropical storms, here in New Jersey. When selecting an installer for your solar panel system, be sure to choose a company that has experience abiding by the strict building codes that govern the installation and ensure that panels resist being uplifted by the wind.
