Solar Panel Cleaning in Boise & the Treasure Valley
Idaho dust, pollen, and wildfire ash can cut solar output by up to 25%. We restore full power with deionized water and warranty-approved low-pressure cleaning — most arrays done from the ground, without anyone standing on your panels.
Real Solar Panel Cleaning in Action
Our technician using a water-fed pole with pure water to safely clean rooftop solar panels—no ladders on the array, no harsh chemicals.
Dirty Panels Cost You Money Every Sunny Day
Southern Idaho is close to a worst-case climate for solar soiling: long rain-free summer stretches, farmland dust on three sides of the valley, heavy spring cottonwood and grass pollen, and late-summer wildfire smoke that settles as a fine ash film. Nothing washes it off between May and September, so the loss compounds through exactly the months your array should produce the most.
Up to 25% Efficiency Loss
Dust, pollen, and hard water deposits scatter sunlight before it reaches the cells. Low-pitch arrays lose the most because rain never rinses them clean.
Faster Payback
Every kilowatt-hour you lose to soiling extends your payback period. Recovering that output typically covers the cost of the cleaning in the same season.
Protects the Hardware
Bird droppings and baked-on sap create permanent hot spots that damage cells over time. Regular cleaning removes them before they etch the glass.

“Gutter cleaning was quick and thorough. They showed me before/after photos from the roofline. Best service we've had in Meridian.”
“Hard water stains I thought were permanent came right off. The tech explained the whole process and my windows are crystal clear.”
Our Solar Panel Cleaning Process
The same pure-water system we use for windows is what panel manufacturers recommend for glass: no detergents, no abrasives, no pressure.
Inspection and Cool-Down Check
We inspect for cracked glass, loose mounts, lifted seals, and bird nesting under the array, and photograph anything worth your attention. We only clean when the panels are cool — spraying cold water on 150-degree glass risks thermal shock.
Dry Debris Removal
Leaves, cottonwood, seed pods, and loose grit come off first. Wetting abrasive grit before removing it is how DIY cleaning scratches the anti-reflective coating.
Deionized Water Wash
Our system strips every dissolved mineral out of the water before it touches your array. Pure water is aggressively absorbent — it lifts soiling on contact and dries with zero spotting, which matters enormously in a hard-water valley like ours.
Soft Brush, Low Pressure
Carbon-fiber water-fed poles carry a soft-bristle brush across the glass with no weight on the panels and no one walking the array. No high pressure, no harsh chemicals, nothing that voids a manufacturer warranty.
Rinse and Verify
A final pure-water sheeting rinse leaves the glass to dry spot-free. We walk the perimeter, confirm clean coverage on every panel, and flag any maintenance concerns for your installer.
Warranty-Safe, Fully Insured
The fastest way to damage a solar array is to clean it the wrong way. Here is exactly what we avoid and why.
No pressure washing
High pressure forces water past panel seals and into the junction box. It is the single most common cause of warranty denial after a cleaning.
No detergents or degreasers
Soap residue attracts dust within days and can haze the anti-reflective coating permanently. Pure water needs no additive.
No abrasive pads or squeegee scraping
Micro-scratches in the coating permanently reduce light transmission — the damage never washes off.
No walking on panels
Foot pressure creates invisible micro-cracks in the cells that show up months later as dead strings in your output data.
No tap water
Treasure Valley hard water dries to mineral spots that block light almost as well as the dust you just removed.
Licensed and insured
Fall protection, roof-safe access, and full liability coverage on every job — your roof and array are protected.
