Hanford solar panel cleaning, done gently

Hanford gets plenty of sunshine, which is why so many rooftops in town have solar. The catch is that the same dry weather that makes solar worthwhile also leaves panels dusty. Fields, dairies and unpaved roads around town send up fine dust whenever the wind picks up or a tractor makes a pass, and harvest season adds even more. Pollen sticks to the glass in spring, ash can settle during fire season, and pigeons leave droppings that block light in concentrated spots. With little to no rain from late spring through fall, that film just keeps building.

Many panels have a coating on the glass that abrasive pads and high-pressure spray can damage. So we keep it gentle: soft brushes and purified water, with no harsh chemicals and no pressure washer. Purified water has the minerals removed, which matters in an area with hard water, because it dries without leaving spots. We wet the panels first to soften dried dust and droppings, brush each one evenly, then finish with a spot-free rinse. Where it’s practical, we work from the ground with a water-fed pole. We also check under the array for leaves and nesting debris.

Most Hanford homeowners clean their panels every six months to a year, and homes next to farmland or with heavy bird activity often need it more. A good rhythm is once after spring pollen and again after harvest dust settles in late summer or fall. Early morning, while the glass is still cool, is the best time to clean, and our day starts at 5am. We also clean ground mounts, carports and solar on farm and commercial buildings around Kings County.
