what’s the best way to clean your solar panels

Keeping your solar panels clean is key to getting the most out of your investment. Dust, pollen, and bird droppings can block sunlight and reduce efficiency by up to 25%. The best way to clean them is with a soft brush or sponge and plain water. Avoid harsh chemicals or abrasive tools that could scratch the surface or damage the protective coating.

For most homeowners, cleaning solar panels twice a year is enough unless you live in a dusty area or near trees. If your panels are hard to reach, use a hose with a gentle spray nozzle or consider hiring a professional. Safety should always come first, so never climb onto the roof without proper equipment. Regular cleaning ensures your system runs efficiently and lasts longer.
