Professional Solar Panel Cleaning in Southern Wisconsin
Get Everything Your System
Was Built to Produce.
Same Care We Gave the Capitol.
Left alone, hard water, pollen, and pine debris bake into the glass and create hot-spots that shorten the useful life of your array — and quietly void your warranty. We follow every manufacturer's cleaning spec so your panels stay under warranty and keep producing for their full 25–30 year design life. On the Wisconsin State Capitol's 16-year-old array, that discipline delivered a measured +16.7% production lift in a single visit.
Just give us your address — we'll size your system with satellite imagery and reply within 24 hours. Residential & commercial. No mandatory site visit. No high-pressure sales.

Three things every panel owner deserves.
Asset & Warranty Protection
We use only manufacturer-approved methods, so cleaning never voids your warranty — and never lets baked-on debris turn into hot spots and cell damage.
Measured Production Recovery
Dirty panels lose 5–15% output annually (NREL). On the Wisconsin State Capitol's 16-year-old array we delivered a documented +16.7% efficiency jump. Proof, not promises.
100% Deionized, Spot-Free Finish
Our custom-built mobile DI rig & soft rotary brushes leave a spot-free finish with zero harsh chemicals. We bring our own water & power — no hookup to your utilities.
Owner-operated — a small local team on your roof, not a rotating crew.

Production recovered
We just cleaned the Wisconsin State Capitol.
Installed in 2009. Never cleaned. 16 years of pollen, dust, and bird debris — gone in one visit.
If Wisconsin's most iconic rooftop trusted us with the work, your property is in good hands too.

The math: a single $110/yr loss will pay for years of professional cleaning — and most Southern-Wisconsin homes only need cleaning once or twice per year.
Get the full potential out of your solar investment.
Your panels were engineered to produce for 25–30 years. Regular professional care is how you help them reach that full output potential — and stay warranty-protected the whole time.
Preserves your warranty
Every major manufacturer — LG, Panasonic, REC, Q Cells, SunPower — requires manufacturer-spec cleaning to keep the 25-year warranty intact. We follow every one of them.
Prevents hot-spot damage
Bird streaks and baked-on pollen create localized hot-spots that permanently degrade cells and shorten the useful life of your array. A gentle rinse cycle every 6–12 months prevents it.
Extends the useful life
Panels are engineered for a 25–30 year design life — but only if the glass stays clear and the anti-reflective coating stays intact. Regular professional care protects both.
Three steps. No surprises.
From first message to a measurable production lift — usually inside a week.

Same panels. Same sun. Same weather. The only difference? A professional cleaning.
So Was the System Aging or Just Dirty?
If this were degradation, the panels would lose ~0.5% per year — not 22% overnight. Here's how the two compare:

The reason most owners should clean isn't the money.
Recovering 5–15% of lost production is the headline. What we actually protect is harder to put on a spreadsheet — your warranty, your insurance claim history, and the 25-year design life you paid for.
Most warranties require cleaning.
Tesla, SunPower, LG, LONGi, JinkoSolar — every major manufacturer publishes maintenance language in their warranty docs. Ignore it for years, and a future claim can be denied as “owner negligence.”We document every cleaning so you have proof if you ever need it.
See what each manufacturer saysInsurance adjusters look for neglect.
If a hailstorm or fire ever damages your array, your insurance claim depends on showing the system was maintained. Cleaning records are documented maintenance. One inspection per year — with photos, irradiance readings, and a service log — is often the difference between a paid claim and a denied one.
Pollen, bird droppings & minerals etch glass over time.
Wisconsin's 18–20 grains/gallon hard water leaves mineral residue. Pollen forms acidic biofilm. Bird droppings create localized hot-spots that can permanently damage individual cells. Cleaning isn't cosmetic — it's the difference between a 25-year panel and an 18-year one.
Who's on your roof matters.
We're owner-operated — you'll always work directly with our team, never a rotating crew. Fully insured, OSHA-certified, locally owned.No subcontractors, no rotating crews, no walking on your panels. Same hands every visit, manufacturer-approved tools, same care I'd give my own array.
Common Questions
Doesn't rain clean my solar panels?
This is the biggest myth in solar. Rain doesn't clean panels—it actually makes them dirtier. Rainwater contains dust, pollen, and minerals that dry into a film. Bird droppings and tree sap don't wash off either. Only professional cleaning removes the buildup.
What cleaning method do you use?
We use soft brush heads, biodegradable soap, and deionized water—no pressure washing, no harsh chemicals. Our method follows official manufacturer guidelines and won't void your warranty. Zero residue, every time.
