what’s the best way to clean solar panels

Keeping 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 depends on your setup, but a few simple steps work for most systems.

Start with a soft brush or microfiber cloth and plain water. Avoid harsh chemicals or abrasive tools that could scratch the panels. If you’re dealing with stubborn grime, a mild soap solution can help, but always rinse thoroughly afterward. For rooftop panels, safety comes first—use a long-handled tool or hire a professional if you’re not comfortable climbing. Regular cleaning, especially after heavy pollen or dust storms, keeps your system running smoothly.
