Solar panels are easy enough to maintain that you can do it yourself! Inspect the panels on a periodic basis to remove any debris or dirt. Panels installed in dusty areas may require more frequent inspection.
3 simple steps to clean your solar panel:
1.) Each solar panel is different so review the instruction manual from the manufacturer before cleaning. Some panels are sensitive to certain chemicals and others may have fragile components.
2.) Before washing the glass make sure that all the wirings are tight and that there aren’t any cracks in the module.
3.) Cleaning a solar panel is as simple as cleaning a window. Grab a bucket full of water, a soft sponge or towel, a drying cloth that won’t scratch and cleaning soap.
