What network specialists do
- Soft-bristle brush — nylon or microfiber, never metal or rigid plastic
- Softened water — DI (deionized) water or reverse-osmosis, no mineral residue when it dries
- Telescoping carbon-fiber pole — keeps the specialist off the roof when possible
- Hand-cleaning only for difficult areas — pollen film, baked dust, ash deposits
- No pressure washing, ever — even at low PSI; manufacturer warranties prohibit it
- No detergents — the softened water alone cleans; soaps leave residue that attracts more dust
- Before/after monitoring screenshot — from the homeowner's Enphase / SolarEdge / SMA app, included in the post-visit report
Why pressure washing voids the warranty
Solar panels are sealed against the elements with EVA encapsulant and a layer of glass on top. Pressure washing — even at residential 1500–2000 PSI — can force water past the edge seals, around the junction box gasket, and into the cells. Once moisture is inside the panel, it causes delamination, hot-spotting, and eventual cell failure. Every major manufacturer (LG, SunPower, REC, Panasonic, etc.) explicitly excludes pressure-wash damage from their warranties.
Network specialists won't use pressure washing because doing so voids your warranty — and they're paid by the directory to do this right. Cheap operators who pressure-wash are how homeowners lose $4,000+ panel warranties for a $99 quick-clean.
Recovery, documented: every clean includes screenshots of your monitoring data (Enphase, SolarEdge, SMA, etc.) showing pre-clean vs post-clean kWh, weather-normalized over the first sunny week. Soft-brush + softened-water typically restores 6–12% of production on a panel that hasn't been cleaned in 6+ months — but the actual number depends on what landed on your panels and how long it sat. We measure, we don't guess.
What's in the post-visit report
- Before/after monitoring screenshots showing kWh/day
- Notes on any maintenance items observed (loose connectors, mounting wear, etc.)
- Recommendation for next clean date (typically 12 weeks out)
- Bird-buildup observations
Pricing details
- 10–14 panels (~4–6 kW) — $189
- 15–22 panels (~6–9 kW) — $229
- 23–32 panels (~9–13 kW) — $259
- 33+ panels — $289+ (custom-quoted per network specialist)
- Difficult-access (2nd story, pitched roof) — typically +$40
- Post-fire emergency surcharge — +$60 (still cheaper than other operators' post-fire pricing)
