Dirty solar panels lose up to 30% of their energy production. Pollen, dust, bird droppings, and mineral deposits accumulate fast in Montana. Our professional solar panel cleaning restores your panels to peak efficiency — protecting your investment and maximizing your savings.
Every layer of grime on your panels is lost electricity and lost savings. Montana's pollen season, agricultural dust, and mineral-rich water leave heavy deposits on solar glass — deposits that don't rinse away in rain.
Studies show dirty solar panels can lose 15–30% of their energy output. That's 15–30% of your expected savings gone with every billing cycle.
Rain removes loose dust but leaves mineral deposits, pollen, and bird droppings behind. Only professional cleaning with purified water restores true panel clarity.
Many solar panel manufacturers recommend regular professional cleaning to maintain warranty coverage. We use methods that won't scratch or void manufacturer guarantees.
Eastern Montana's agricultural dust, cottonwood pollen, and mineral-laden water create particularly challenging buildup on solar glass.
Solar panels are a significant investment. Clean panels produce maximum output, shortening your payback period and increasing lifetime savings.
We use soft brushes, purified water, and appropriate pressure to clean panels without scratching, cracking, or damaging the protective coating.
We inspect each panel for damage, hot spots, or debris under panels before cleaning begins.
Loose debris — dust, leaves, pollen — is brushed away first with soft bristle brushes to prevent scratching.
We use deionized, purified water to dissolve mineral deposits and grime without leaving residue or water spots.
Each panel is individually checked for spots, streaks, or remaining deposits. We don't leave until every panel is spotless.
Solar panel cleaning is priced per panel or per watt of installed capacity. We offer residential and commercial solar cleaning throughout Eastern Montana.

We recommend cleaning twice a year — spring (after cottonwood pollen season and before peak summer production) and fall (before winter). If you're near agriculture or see significant bird activity, more frequent cleaning may improve your output meaningfully.
Not with our method. We use only soft-bristle brushes and deionized water — never abrasive pads, harsh chemicals, or excessive pressure. Our approach is safe for all panel brands and protective coatings.
Yes — we turn off the solar system before cleaning as a safety precaution and because wet panels can generate unexpected voltage differences. We handle this as part of our standard process.
Rain removes loose surface dust but leaves behind mineral scale, bird droppings, pollen, and agricultural residue that require professional cleaning to remove. Studies consistently show professionally cleaned panels outperform "rain-cleaned" panels by 10–25%.
