What happens to solar energy when it rains?

But if you have solar or are thinking about installing panels on your home, you may wonder what happens to the energy your solar system produces when it rains. The short answer: your solar panels will still capture and convert light into electricity during rainy or cloudy weather.

Why do solar panels need rain & sun?

One surprising benefit of rain and sun is their ability to clean solar panels. Over time, dust, pollen, bird droppings, and other debris can accumulate on the surface of the panels, reducing their ability to convert sunlight into electricity.

How much electricity will my solar panels generate?

* The amount of electricity your solar panels will generate will depend on the density of cloud coverage or extent of rain. If it's sprinkling or clouds come and go throughout the day, your energy generation will be higher than it will be during a day of long, heavy downpour or dense, widespread clouds.

How do solar panels generate electricity?

Solar panels generate electricity by converting sunlight into usable energy through photovoltaic (PV) cells. Excess energy produced during daylight hours is sent back to the electric grid through net metering, allowing homeowners to receive credits for their contribution.

How do solar panels work?

Solar panels work even on days with heavy cloud cover and snow and can still generate electricity during reduced sunlight hours. The light that filters through the clouds still provides enough coverage to activate the solar power system's photovoltaic (PV) cells and convert sunlight into electricity.
