Solar panel cleaning in Bass Lake, CA

A solar array at the lake has a lot going for it, since the mountain sun is strong. But panels sitting among pines collect a surprising film. Yellow pollen covers the glass every spring, fine dust and tree debris settle in, and sap or droppings can bake onto the surface. Needles and twigs also slide down and lodge along the lower edge of the array. Anything sitting on the glass blocks light, so your system can’t produce what it could. A quick look from the ground may not show it, because a thin film of pollen is easy to miss until the panels are clean.

We clean panels with soft brushes and purified water, not harsh scrubbing or high-pressure spray. Many panels have a coating that abrasive pads can scratch, and purified water dries without leaving mineral spots. Where it makes sense, we work from the ground with a water-fed pole, and otherwise we access the roof with care. We also look under and around the array for leaves and nesting debris. Rooftop systems and ground-mount arrays are both fair game, and we can clean the gutters during the same visit. If your array sits partly in shade, we’ll point out anything nearby, such as overhanging branches, that you may want to deal with.

Timing is simple. A cleaning in late spring, after the pollen has come down, is a natural fit, and some owners add another in the fall once the dry season has left its dust. Because the work is outside, you often don’t need to be at a second home. We’re based in Fresno and Clovis, and we serve both homeowners and commercial properties. We’re licensed and insured, estimates are free, and our 100% satisfaction guarantee means that if your panels don’t look right, we come back and make it right.
