How Do Clouds and Rain Affect Solar Panels’ Performance?

You probably have some questions if you’re considering setting up your home or business with solar power. Aside from cost, installation, and benefits, you want to know how well solar panels work if you’re going to truly rely on the sun. Nighttime isn’t suitable for gathering solar power, but what about cloudy, rainy days? How do clouds and rain affect solar panels’ performance, and how can you maximize their efficiency?

Cloudy Days

When clouds cover the sun, solar power fluctuates. The energy intake depends on the types of clouds and their position in the sky. High, thin clouds block little to no direct sunlight. With direct sunlight, a solar array creates a lot of power to store in an off-grid lithium battery bank. While cloud cover decreases the amount of sunlight the panels receive, they’re not completely cut off. You’ll only get 10 to 25 percent of what you’d derive from a clear sky, but it’s better than nothing. Overcast weather can occasionally also help disperse light so solar panels aimed in different directions can absorb slightly more light than normal.

Rainy Days

You can’t have rain without clouds, so the abovementioned rules also apply to rainy days. The rain itself has little to do with energy conversion. Surprisingly, many experts indicate that rain keeps the panels clean and free from dust and dirt. Clean panels work best because they are at maximum absorption capacity.

Snow Days

When considering how clouds and rain affect solar panels’ performance, don’t forget the winter season. Snow clouds from lower to the ground are thicker, so they cut off direct sunlight. Snow and ice can cover and coat your panels, so be sure to clear them off after a snowfall. The good thing is snow reflects sunlight, which increases the amount your panels are getting.

Other Ideas

Experts suggest setting up your solar power system according to the season. This means adjusting your solar panels based on the path of the sun, which takes a longer course in the summer months. Investing in a portable system that adjusts with the sun’s path is worth your consideration. You can also supplement your solar power with an off grid lithium battery bank, which allows you to store that solar power for later use. Solar panels are a smart and environmentally conscious investment—maximize that investment by maximizing their performance. As long as you keep your panels clear and adjust their position to absorb optimal sunlight, you’ll get the maximum amount of sunlight, even on cloudy days.
