Hiring a professional team to clean solar panels is your best choice. While solar panels are a low-maintenance investment, "low-maintenance" doesn't mean "no-maintenance." Over time, a film of dust, pollen, bird droppings, and pollution builds up on the surface. This "soiling" prevents sunlight from reaching the cells, directly reducing the amount of electricity your system generates. While rain might wash off light dust, it won't remove stubborn grime, which can silently chip away at your energy savings—potentially cutting efficiency by 5% to 30%. Tempting as it may be to hose them down or scrub them yourself, a DIY approach carries significant risks. First, there is the obvious danger of personal injury. Working on a sloped roof with water and cleaning tools is hazardous without proper safety training and equipment. Second, you risk damaging your expensive equipment. Using tap water can leave mineral deposits that create new hotspots and block sunlight. Abrasive brushes or high-pressure washers can scratch the panel's glass or anti-reflective coating, while harsh detergents can compromise the seals—potentially voiding your warranty. Hiring a professional service mitigates these risks and ensures the job is done right. Grayson's professionals use specialized, non-abrasive tools, such as water-fed poles with soft-bristle brushes, and purified, de-ionized water that cleans flawlessly without leaving residue.
