It’s Raining Solar Energy

If you have lived anywhere up and down the east coast of our beautiful United States, you’ve likely encountered the usual summer sprinkle. Actually, it’s more of a summer deluge that threatens to sweep away the very ground underneath your feet. While you’re busy trying to keep your life possessions from floating away, you might also think back to those solar panels you have sitting on your roof. How will this summer downpour affect your solar panel efficiency?

Here’s what you need to know:

Solar Panels Work in the Rain.

When the sky grays with bursting storm clouds, your solar panels don’t just go kaput. You can still get great use out of them because sunlight still slivers through those dreary clouds.

While the panels may not reach their highest efficiency level on these days, you will still receive considerable amounts of energy from them. In fact, you can get 10–20 percent of the normal solar panel efficiency on a cloudy, drizzling day.

 

Rain Can Boost Solar Panel Efficiency.

In addition to still receiving necessary energy, your system will actually benefit greatly from a nice rain shower. The rain will clear away any dust and dirt from the panels, leaving them sparkling clean and ready to drink in the sunshine again when the rain lets up.

At the same time, the rainy weather will cool off the solar panels. Did you know that solar panel efficiency actually drops when they reach too high a temperature? They do, and the cool weather will help them regain some of that efficiency.

 

High Quality LG Solar Panels Keep Up the Efficiency.

Although you cannot exactly control the natural weather factors for the most efficient system, you can control one aspect: the type of solar panels used. The highest quality solar panels will keep more energy flowing through your home’s veins than other models.

At Palmetto, we use the LG solar panels. These panels are designed to receive sunlight from a broad range of the solar spectrum, helping them capture more of the sun’s energy for your benefit.

How exactly would this translate into more energy on a rainy day? During a sunny day, the sunlight usually concentrates in the direction of the sun’s position. On a rainy day, however, the sunlight gets dispersed due to the layer of clouds blocking its direct rays. As the sunshine peeks through the clouds in its diminished intensity, the LG solar panels will capture that light at varying angles.

Because of its specific design, the LG solar panels have one of the highest ratings for overall solar efficiency. And that efficiency only boosts your solar energy system on drippy, drowsy days.

While your solar panels might not work at maximum capacity during the rain, you do still gain clean solar energy on these days. In addition, the rain helps to clean and cool your solar panels, refreshing them for better efficiency when the sun does come out again. The next time you see a dreaded downpour during a summer forecast, you can sit back and relax. You know that your solar energy system will actually benefit from it.
