Solar Panel Cleaning in Greenville, SC

Rain helps, but it rarely finishes the job. Light rain often leaves a dusty film behind as it dries, and it won't wash off bird droppings, sticky tree sap or caked-on pollen. Greenville's spring pollen season coats everything in a yellow layer, and panels at a low tilt hold onto debris longer because water runs off them slowly. Panels near trees, roads or construction collect grime faster. A good habit is to compare your system's monitoring numbers from month to month — an unexplained drop on sunny days is often the clearest sign the panels need cleaning.
