Over time, solar panels get dirty and dusty, and need to be cleaned regularly to ensure maximum power generation. If solar panel maintenance is neglected for too long, a layer of baked-on dirt can build up, making them very difficult to clean. The solar panels on this house at Peregian Springs needed a good maintenance clean. Also, the metal frame at the bottom of the panels was covered in a black unsightly grime. We cleaned the solar panels using a hose fed pole with a soft-bristled brush, and cleaned the metal frame with the Jetts pressure wand.
