How to deal with solar power generation and rain

Do solar panels work if it rains?

The short answer: your solar panels will still capture and convert light into electricity during rainy or cloudy weather. So, if you live in an area that gets a lot of rain or has a number of overcast days throughout the year, don’t rule out solar panels.

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.

Do heavy rain solar panels generate a lot of energy?

In heavy rain solar panels generate 10 % – 20 % of their maximum generation. However, there are some mitigating factors to consider. For example, if the rainfall is light and steady, it may actually help keep the panels clean which could improve efficiency.

How does rain affect solar panel efficiency?

Solar panel efficiency is measured by the amount of sunlight that hits the panel and is converted into electricity. Events like rain, snow, and hail can all reduce the amount of sunlight that hits the panel, which in turn reduces efficiency. In heavy rain solar panels generate 10 % – 20 % of their maximum generation.

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.

Is rain a deterrent to solar power?

Rainy weather should not be a deterrent when deciding if solar is right for you. Despite what you might think, rain isn’t a death knell for solar power. In fact, in many ways, rain can actually be helpful to your system. Solar panels are most efficient when they are clean and free of debris.
