A 2011 study by the World Academy of Science, Engineering and Technology concluded that “accumulated dust on the surface of photovoltaic solar panels can reduce the system’s efficiency by up to 50%.” Other contaminants can be even worse. Panels must be cleaned for optimal performance. The small cost of regular cleaning with a specialty solar product yields big savings by increasing panel output.
Solar Panel Wash (SPW™) was specially formulated to be compatible with the films that are used on solar panels. It cleans all types of solar panels without oxidizing or abrading aluminum rails and mounting apparatus. Many common soaps used for washing cars or windows contain alkalines that promote oxidation and require deionized water for a spot-free rinse. Dust, bird droppings, pollution, pollen, tree sap, plant matter residue, etc., all reduce the overall effectiveness of solar panel generation capacity.
