Commercial solar panels lose up to 30% of their energy output when soiled. SolarAbility's professional soft-wash cleaning service restores full performance — without risking damage to your panels or warranty.
Illinois conditions are tough on solar panels. Pollen in spring, bird droppings year-round, dust from highways and agriculture, and industrial particulate in urban areas — all of it silently eats away at your energy production.
Illinois pollen season coats panels in a thick yellow film that blocks sunlight and clings even after rain.
The most damaging soiling type — highly acidic and concentrated, causing up to 30% output loss on affected cells.
Properties near highways, farms, or industrial areas accumulate a fine dust layer that compounds over time.
Based on industry studies. Actual output varies by panel type, soiling composition, and Illinois seasonal conditions.
Every cleaning is performed by trained technicians using methods that protect your panels, preserve your warranty, and maximize your energy recovery.
Low-pressure deionized water with biodegradable cleaning solution. Safe for all panel brands and warranties. Leaves panels streak-free and spot-free with no residue. High-pressure washing voids most panel warranties — we never use it.
Set it and forget it. We build a custom cleaning schedule around your property's soiling rate — monthly, quarterly, or seasonal. Includes priority scheduling, performance checks, and discounted rates vs. one-time cleanings.
Every commercial cleaning includes a visual inspection of your panels, racking, and wiring for visible damage, corrosion, or loose connections. You get a written report — at no extra charge.
We evaluate your system size, roof type, soiling level, and access requirements. You get a written quote — no surprises.
We work around your business hours and operations. Most commercial cleans are completed early morning to minimize any disruption.
Our technicians use low-pressure deionized water and biodegradable solution to fully remove soiling without risking panel or warranty damage.
You receive a written condition report. We recommend a cleaning frequency based on your property's specific soiling patterns.
