CSLB-verified
C-46 (Solar) or C-39 (Roofing) or business license appropriate to scope. License number disclosed before scheduling.
Every month, something different lands on your panels. Pollen in March. Central Valley dust in July. Wildfire ash in September. Below is when each season starts — and when, exactly, to clean.
A directory of vetted soft-brush / softened-water solar-cleaning specialists across Yolo, Sacramento, Solano, and Placer counties. Every partner uses warranty-safe methods — never pressure-washing.
When you sign up for the seasonal plan, we match you with a vetted local cleaner whose schedule aligns with the calendar. Same cleaner each visit. Quarterly billing. Cancel anytime.
Wipes off the sticky almond film before the heat bakes it into a varnish.
Catches the dust before it stacks. Production typically recovers 7–10% on the first sunny day after.
Same-week. Network specialists prioritize plan customers for emergency post-fire scope.
Bird buildup, rain streaks, plus a microcrack/connector inspection before the low-sun months.
Solar cleaning is the wild west of the solar industry — some operators pressure-wash, some use streak-leaving detergent, some don't carry roof-work insurance. We don't onboard cleaners we wouldn't put on our own roof. The checklist below is the floor, not the ceiling.
C-46 (Solar) or C-39 (Roofing) or business license appropriate to scope. License number disclosed before scheduling.
Soft-bristle telescoping brush + softened deionized water. No pressure washing — it voids panel warranties.
Cleaning practices verified against Panasonic, REC, Q CELLS, LG, and SunPower warranty terms.
Current certificate with roof-work coverage. Your home named as additional insured for the visit.
OSHA-compliant fall-arrest setup. Workers' comp current. Required for any roof access.
Pre-clean and post-clean kWh reading recorded from your monitoring app. You see the lift in writing.
Plain softened water + soft brush. No soap, no streaks, no residue. Manufacturer-approved technique.
Flat per-visit price. No surprise upcharges for panel count or roof pitch. Quoted before the truck leaves.
Built from NREL soiling-loss research and PG&E E-TOU-C rate data for the Sacramento Valley climate. Numbers below are conservative — what you're actually losing might be more.
Dollar figure uses PG&E E-TOU-C peak rate (~$0.34 / kWh) for ~30% of generation, off-peak for the rest. Conservative estimate.
Solar panels don't clean themselves, and rain alone doesn't bring them back. In the Sacramento Valley between June and October, panel performance falls off a cliff — NREL soiling-loss research puts the typical production hit at 6–12% on panels that haven't been cleaned in 6+ months, and the actual number is often higher in the dust-and-fire-exposed parts of Yolo and Solano. Most homeowners don't realize this until they look at their monitoring app and see their July kWh numbers running 15% below last July.
The cleaning side of the solar industry is the wild west. Some operators pressure-wash (which voids your panel warranty). Some use detergent that streaks. Some quote $400 for what should be $180. We screen network specialists for soft-brush methodology, softened water, manufacturer-compatible practice, and CSLB-clean operating status only.
We're new. The seasonal calendar above is the start of an honest conversation about when to clean, when to skip, and what a clean done right actually looks like.
First clean within two weeks. Four-times-a-year cadence after that, on autopilot. Same vetted network specialist each visit.
