NovaLee Solutions cleans residential solar arrays across Long Island, NY using soft-brush rinsing and deionized water — never abrasive scrubbers or harsh chemicals that void panel warranties.

Frequently asked questions
Do I really need to clean my solar panels on Long Island?
Most Long Island arrays do not need monthly cleaning, but pollen-heavy springs and bird droppings can knock 5-10% off production. An annual or every-other-year clean typically pays for itself in restored production.
Doesn't rain clean my panels enough?
Rain clears loose dust but not pollen film, bird droppings, tree sap, or the salt-air haze common on the South Shore. Those need a soft-brush wash with deionized water.
Can I clean my solar panels myself?
Technically yes, but it is not recommended. Walking on the roof voids most workmanship warranties, hose water leaves mineral spots that reduce production, and pressure washing voids panel warranties. We send a trained crew with the right gear.
How much extra production will I get?
Typical post-clean recovery on Long Island is 3-8% of annual production, more if there has been heavy bird activity or a pollen-heavy spring.
Will you clean panels installed by another company?
Yes. We clean any brand of panel as long as the array is in safe condition. We do not clean panels with visible cracks, hot spots, or active warranty issues without addressing those first.
