Do You Need to Clean Solar Panels?

Solar panels rely on taking in the sun’s rays to convert sunshine into electricity. Solar panels are typically placed on the roofs of buildings, including residential homes. A common question for new solar panel users is this: “How often do I need to clean them?”

Rainstorms are really good at cleaning solar panels; they’re nature’s way of cleaning so you don’t have to. However, if you live in an area that doesn’t get rain often, you may need to get a hose and spray them yourself.

What makes solar panels dirty? Typically, wind-blown dust and pollen are the chief culprits. Occasionally bird poop might interfere as well. Dirty panels’ output may decrease by 5 to 20 percent, so it is a good idea to keep in mind their cleanliness and attend to them as needed.

Basically, how often you should clean your solar panels depends on a couple factors. First, your location matters. If it rains a lot, you’re good. If it doesn’t, you’ll need to clean them more often than not. Next, what does the tilt of the panels look like? The steeper ones stay cleaner than the more horizontal ones. Thirdly, do you live in a windy, dusty area? If so, you’re apt to need a regular schedule of cleaning the panels every couple weeks or months. Also, if the electric rate is high it might be time for a cleaning. Finally, cost factors in– how much is it going to cost you to clean the panel(s)? Can you do it yourself with a ladder and hose or do you need to hire someone else to come do it professionally?
