Dust-free solar panels in Selma

Selma’s long, sunny summers are great for solar, but the same dry months bring the most dust. Panels near vineyards, orchards and dirt roads pick up a visible film as fields are worked, and late summer is usually the worst, when the raisin harvest stirs up dust day after day. Spring pollen adds a sticky coat, fire season can leave a layer of ash, and birds leave droppings that block light in concentrated spots. Since summer passes with little or no rain, rooftop panels rarely get a natural rinse, and even when rain does come, it tends to leave a dirty residue behind.

We clean panels gently. Many panels have a coating on the glass that abrasive pads can scratch and high-pressure spray can damage, so we skip both. Instead, we wet the panels with purified water to soften dried dust and droppings, then work across the array with soft brushes, often on a water-fed pole. Because the minerals have been removed from the water, it dries spot-free instead of leaving the white marks that Valley hose water often does. We also look under and around the array for leaves and nesting debris, and we’ll let you know if we see signs of birds moving in.

Lots of Selma homes have rooftop systems, and farms and ag properties around town often have ground-mount arrays or panels on shops and barns. We clean all of them, along with commercial rooftops and carports. Many owners schedule a cleaning after spring pollen and another once harvest dust settles in the fall. Early mornings are ideal because the glass is still cool, and our day starts at 5am. If pigeons are nesting under your panels, we can add bird proofing to the same visit. Estimates are free, we’re licensed and insured, and our satisfaction guarantee covers every array.
