How to Clean Residential Solar Panels Safely and Easily
Regularly cleaning your residential solar panels is key to keeping them efficient and extending their lifespan. Dirt, pollen, and bird droppings can block sunlight, lowering energy output by up to 25%. You can clean panels yourself using cold water, mild detergent, and a soft-bristle brush—or hire professionals for hard-to-reach areas. Always turn off your system before cleaning, avoid harsh chemicals, and work during cooler hours for best results. Clean panels not only boost performance but also protect your solar investment year-round.
