How Often Should I Clean My Solar Panels?

Having an official solar panel maintenance schedule is not necessary because there’s nothing, you’ll need to maintain other than an occasional light cleaning. The most efficient plan is simply to clean the panels as needed. How often you will need to clean your solar panels depends on your climate region and the specific area you live in. Generally late spring or during the summer is recommended after pollen has settled.

Additionally, check your solar power monitoring system routinely. It will indicate when your panels are underperforming. If you notice a decrease in power output from your solar panels, the first thing to check is the cleanliness of the panel surfaces to see if they need cleaning.

3. Rainwater doesn’t do it for you

Most solar panel owner don’t clean their solar panels after it rains because they think they don’t need to because the rainwater will do it for them. But that’s not true. Like how you need to clean your car’s windshield more often during the rainy season, your solar panels need to be cleaned more often as well. So, it is recommended that you don’t rely on rainwater to clean your panels automatically, because it just doesn’t happen.
