Professional Solar Panel Cleaning in Southern Wisconsin
Protect Your $20k+
Solar Investment.
Restore Every Watt.
Hard water, pollen, and pine debris bake into panel glass — creating hot spots that void warranties and quietly steal 5–15% of your output annually (higher in pollen and agricultural zones). Our manufacturer-approved cleaning keeps your warranty intact and your production maxed. On the Wisconsin State Capitol's 16-year-old array, we 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 by Marquis — the only person on your roof.

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.

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.

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:

Beyond The Numbers
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.

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.
