For homeowners whose production has visibly dropped — typically after wildfire smoke or 6+ months of no cleaning. The matched network specialist arrives within 10 business days (faster for post-fire emergencies).
Every one-time clean includes before/after screenshots from your monitoring app (Enphase, SolarEdge, SMA, etc.) — pre-clean vs post-clean kWh, weather-normalized.
Soft-brush + softened-water typically restores 6–12% of production on a panel that hasn't been cleaned in 6+ months. The actual number depends on what landed on your panels (pollen, Central Valley dust, wildfire ash) and how long it sat. If recovery is unexpectedly low, that's usually a sign of something the specialist should look at — a microcrack, a connector issue, or shading — and the post-clean report will flag it.
A one-time clean costs $189–$289. Four one-time cleans a year cost $756–$1,156. The seasonal plan delivers four cleans a year for $236 total — a $500+ savings, plus fire-season priority dispatch and the same specialist each visit.
If you're going to clean more than once, the seasonal plan is the math. The one-time clean makes sense if you're handling an immediate need (post-fire, sale, etc.) and not committing yet.
