What we do
Solar cleaning, done right.
Chemical-free cleaning and clear reporting — for single rooftops and multi-site agency fleets across the Central Valley.
Commercial Rooftop Cleaning
Safe, insured rooftop access for warehouses, depots, and office campuses — soft-brush DI water rinse, zero residue.
Ground-Mount & Carport Arrays
High-reach pure-water systems clean ground arrays and solar carports without ladders on glass.
Public Agency Maintenance
Procurement-friendly contracts for transit agencies, school districts, and county facilities — COI & W-9 ready.
Eco-Friendly DI Water Cleaning
0 PPM purified water lifts dust, pollen, and bird residue — no detergents, no runoff, no warranty risk.
Why it matters
Dirty panels lose money — every sunny day.
Routine cleaning protects the asset you paid to install. Here's what regular service actually does.
Prevent Dirt Buildup & Energy Loss
Central Valley dust, pollen, and ag-film can drop solar output 15–25%. Routine cleaning keeps every kilowatt-hour working.
Protect Your Solar Investment
Soft-bristle DI water cleaning preserves anti-reflective coatings and panel warranties — no chemicals, no abrasion.
Recover ROI On Every Array
Cleaner panels recover yield fast. We document the work so finance and facility teams can see what came back.
Extend Useful System Life
Soiling accelerates hot-spotting and module wear. Scheduled service keeps your asset performing for decades.
Our process
Four steps. Same every visit.
A simple, documented process your facility team can count on — chemical-free, insured, and reported.
- 01
Site walk & safety plan
We review array layout, roof access, and fall-hazard zones before mobilizing. Every job gets a site-specific safety plan.
- 02
Pure-water setup
Our trucks carry on-board deionization. Water exits at 0 PPM so the only thing left on your glass is sunlight.
- 03
Soft-bristle cleaning
Telescopic carbon-fiber poles and module-safe brushes lift dust, pollen, ag-film, and bird residue — never touching coatings.
- 04
Inspection & report
Every visit ends with documentation: photos, panel counts, soiling notes, and any equipment flags for your O&M team.
Eco-Friendly DI Water
0 PPM pure water dissolves dirt without chemicals or runoff.
Insured & OSHA-Trained
General liability, workers' comp, documented fall-protection training.
Zero Chemical Runoff
No soaps, no surfactants, no acids. Public-agency compliant.
