Cleaning your solar panels removes dirt, dust, pollen, and bird droppings that block sunlight and reduce efficiency. A professional cleaning can increase energy output by up to 30%, depending on how dirty the panels were.

While we can’t guarantee an exact percentage increase—since every system and location is different—most homeowners notice a clear spike in performance shortly after the cleaning. It’s one of the easiest ways to maximize production and protect the long-term value of your solar investment.
