Frequently Asked Questions

It's simple math: dirt blocks sunlight. Layers of dust, pollen, bird droppings, and urban smog act as a physical shield over your panels, passively stealing up to 25% of your theoretical energy production. Cleaning them immediately restores that lost revenue.

We recommend bi-annual cleaning for most California properties. However, quarterly service is strongly advised for arrays near high-dust agriculture, construction zones, or intense pollen areas.

Absolutely not. We use a proprietary, laboratory-grade purified water system. De-ionized water acts like a magnet for dirt and evaporates flawlessly spotless. Using chemicals or tap water voids manufacturer warranties and leaves scaling—we strictly prevent that.

Relying on rain to clean your solar panels is like relying on rain to wash your car. It might rinse off loose top-dust, but it fails entirely against "baked-on" grime, sap, and bird droppings. Worse, rain often leaves mud spots behind. Professional agitation is required for true efficiency restoration.

Residential packages start at $150. Pricing is based on array size, roof complexity, and soiling levels. Contact us for a precise quote.
