I’ve been wondering how often people actually clean their solar panels. I understand that dust, dirt, pollen, and other buildup can collect on them, but I’m not sure how much of a difference regular cleaning makes in everyday use.



For someone who has panels installed at home, is occasional cleaning usually enough, or is it better to have them checked and cleaned on a regular schedule? I’m also curious whether people normally handle this themselves or use a solar panel cleaning company, especially when the panels are installed on a difficult-to-reach roof.
