Many homeowners miss one key thing. A layer of dirt can steal much of that energy. In this guide, we’ll explore solar panel cleaning tips.
Why Clean Solar Panels Matter More Than You Think

If your solar power suddenly drops, your panels are probably dirty. This happens even when the sun shines bright. Checking how well your system works is a good idea. You will know just when to clean your panels.
