Residential Solar Cleaning

It depends on how dirty they are. Dust, pollen and marine film cut the light reaching the cells, and in a dry San Diego summer that builds up for months without rain to rinse it. If your output has drifted down and nothing else has changed, soiling is the usual explanation.

Not the way we do it. We use deionized water and soft tooling, no detergents and no abrasives, which keeps the cleaning within what panel manufacturers allow. Pressure washing a panel array is what puts a warranty at risk.

It dries without leaving mineral residue. Ordinary tap water leaves spots on the glass as it evaporates, which is the opposite of what you want on a surface whose whole job is letting light through.

Once or twice a year for most roofs. More often if you are under trees, near active construction, or somewhere the marine layer settles heavily.

RadPad is locally owned and operated in San Diego, serving San Diego County, including Oceanside, Carlsbad, San Elijo Hills, Encinitas, Solana Beach, Del Mar, Rancho Santa Fe, Del Sur, La Jolla, San Clemente, and Dana Point.

Unless a RadPad technician is performing an interior service, you do not always need to be home during the service. However, RadPad will always confirm with you ahead of time if we need access to your property.
