Solar panel cleaning in Sanger, gentle and spot-free

Sanger gets a lot of sun, which is exactly why so many homes, farms and businesses here have gone solar. The catch is that the dry season brings the most sun and the most dust at the same time. Panels near orchards, vineyards and farm roads can grow a visible film during harvest and on windy days, and spring adds sticky pollen. In a bad fire season, ash can settle across the glass as well. Since summer usually goes by with little or no rain, rooftop panels around town rarely get a natural rinse when they need it most.

We never pressure wash panels. High-pressure spray can damage the glass, its coating and the seals around the edges. Instead, we wet the panels with purified water so dried dust and droppings soften, then clean each one with soft brushes, often using a water-fed pole from the ground. Purified water has the minerals removed, so it dries without the spots that hose water tends to leave. A final rinse carries away the loosened dirt. We also check under and around the array for leaves, nesting material and bird activity, and let you know what we find.

In summer, early morning is the best time to clean solar, while the panels are still cool, and our day starts at 5am. Many Sanger homeowners schedule a cleaning after spring pollen and another in late summer or fall once harvest dust settles. If your system has a monitoring app, a dip on clear days is a good hint the panels need attention. We also clean ground-mount systems, carports and arrays on ag and commercial properties. If pigeons are nesting underneath, we can pair the cleaning with bird proofing. We’re licensed and insured, every estimate is free, and we’ll come back if a panel was missed.
