Solar Panel Cleaning FAQ

Two to four times a year for most homes, often timed around monsoon and spring pollen season. Tucson's desert dust, palo verde and mesquite pollen, and dusty monsoon storms all coat panels, and long dry stretches mean little rinses them off.

Usually it makes them worse. Monsoon rain arrives full of blown dust, so it often dries into a muddy, streaky film that blocks more light than the dust alone. Cleaning after monsoon season is one of the highest-value times to do it.

Yes. In dusty, low-rain climates soiling can cut output noticeably — often into the double digits on heavily caked panels. Clean glass lets the system produce as designed, and most owners see production recover after a cleaning, visible in their monitoring app.

Tucson tap water is hard, so hosing panels leaves mineral spots that bake on in the heat and block light like the dust did. We use purified (deionized) water and soft brushes for a spot-free, streak-free finish with no chemicals that could affect your warranty.

Yes. We use manufacturer-safe methods — soft brushes, low pressure, purified water, no harsh chemicals — and clean from the ground where possible. Improper DIY cleaning is the bigger warranty risk, since the wrong brush or pressure can scratch glass or crack cells.

Yes. We remove existing nests and droppings, sanitize the area, and install critter-guard mesh around the array — without drilling panels — so birds can't get back under. Their droppings otherwise corrode and soil the system, so it's a common add-on in Tucson.

Yes. We run scheduled cleaning programs for businesses, warehouses, HOAs, solar carports and ground-mount arrays across the metro, sized to your soiling rate, with before-and-after documentation.
