Solar panel cleaning in Kingsburg, CA

Solar panels in Kingsburg get plenty of sun and plenty of dirt. Panels on homes, barns, packing and farm buildings sit surrounded by vineyards, orchards and open ground, and during harvest and windy spells they pick up a visible haze of dust. Spring pollen adds a sticky film. Smoke from distant fires can leave a layer of ash. Pigeons add concentrated spots of droppings. And because summer passes with almost no rain, there is rarely a natural rinse when the panels need it most. A dusty array can lose output without anyone noticing, since the change comes on slowly.

We clean them the gentle way. Many panels have a coating that scratches under abrasive pads and suffers from high-pressure spray, so we use soft brushes and purified water. Purified water has its minerals removed, so it dries without the spots hose water leaves behind. Where it’s practical, we work from the ground with a water-fed pole, and otherwise we access the roof carefully. Dried droppings get soaked first rather than scrubbed hard. We also check under and around the array for leaves and nesting debris. Every job ends with a final purified water rinse so the glass dries clear.

Many owners schedule a cleaning after spring pollen and again in late summer or fall, once harvest dust has settled. Mornings are ideal, since cool panels are easier on the glass, and we start as early as 5am. We clean rooftop and ground-mount systems, carports, and arrays at farms and commercial buildings. If birds are nesting underneath, we can proof the array in the same visit. Estimates are free, we’re licensed and insured, and our 100% satisfaction guarantee means we come back and make it right. We’ll look over the array before we start and tell you about anything unusual.
