Solar panel cleaning in sunny Visalia

Visalia gets plenty of sunshine, which is why so many rooftops here have panels. The same dry season brings dust. Harvest in the orchards and fields around town, dairies, dirt roads and new construction all put fine particles in the air, and they settle into a film on the glass. Spring pollen adds a sticky layer, and when wildfires burn in the nearby foothills and mountains, ash can coat everything. Summer usually passes with little or no rain, so panels rarely get rinsed when they need it most.

We clean panels the gentle way. Many panels have a coating on the glass that abrasive pads and high-pressure spray can damage, so we stick with soft brushes and purified water. With the minerals removed, the water dries without spots, unlike water straight from a hose. Dried dust and droppings are soaked first so they release without hard scrubbing. Where it’s practical, we work from the ground with a water-fed pole. Otherwise, we access the roof carefully. We also check under and around the array for leaves and nesting debris.

Early mornings are a good time to clean, while panels are still cool, and our day starts at 5am. Most Visalia homeowners schedule a cleaning every six months to a year, often after spring pollen and again in late summer or fall once harvest dust settles. Homes next to farmland may want it more often. We also clean commercial rooftops, carports, ground mounts and solar on farm properties around Tulare County. If pigeons have moved in under your panels, we can clean up and add bird proofing in the same visit. Estimates are free, and we’re licensed and insured for rooftop work.
