Solar Panel Cleaning in Northern Virginia
Pure-water solar panel cleaning across Northern VA. Flat per-panel pricing, deionized water, soft brushes, and a fully insured crew that gets your array back to rated output.
why it matters —
Dirty panels = lost power.
Studies from NREL and academic field tests show that dust, pollen, and bird droppings can knock 5–25% off a panel's output — and in heavy-soil seasons (spring pollen, summer dust storms, fall leaf drop) the drop is even worse. A clean array pays itself back fast.
More kWh, same panels
We pull off the film of pollen, dust, and droppings so your inverter sees the production it was sized for — not a derated version of it.
Safe for every panel
Deionized water, soft brushes, no detergents, no abrasives. Won't void your panel warranty and won't scratch the anti-reflective coating.
Insured roof work
Full general liability, auto, and workers' comp. Water-fed pole rigs let us clean most arrays without ever stepping on your roof.

Frequently asked
How much does solar panel cleaning cost in Northern VA?+
Flat per-panel pricing: $7/panel for 1-story homes, $10/panel for 2-story, $15/panel for 3-story. A typical 20-panel system runs $140–$300 depending on roof height. Final price confirmed same business day before any work begins.
Do dirty solar panels actually lose output?+
Yes — field studies from NREL and several university teams put the loss between 5% and 25% depending on dust, pollen, and bird-dropping levels. In Northern Virginia, pollen season alone can take a noticeable bite out of production until the next heavy rain.
How often should solar panels be cleaned?+
For most Northern VA homes, once or twice a year is plenty — typically after spring pollen and after fall leaf drop. Homes near tall trees, construction, or with heavy bird traffic may benefit from quarterly cleans.
Will cleaning void my solar panel warranty?+
No. We use deionized (purified) water with soft-bristle brushes — the same method panel manufacturers recommend. No detergents, no abrasives, no high-pressure spraying.
Do you walk on the roof?+
Whenever possible we clean from the ground using water-fed pole rigs. On taller or steeper roofs that require access, we use proper fall protection. Either way, we're fully insured (general liability, auto, workers' comp).
What areas do you serve?+
All of Northern Virginia — Great Falls, McLean, Vienna, Reston, Arlington, Herndon, Oakton, Falls Church, and Ashburn. Same trucks, same per-panel pricing across the entire service area.
Can rain just clean my panels for me?+
Rain rinses loose dust but actually bakes pollen and bird droppings onto the glass. A proper pure-water clean is what restores rated output — rain alone usually doesn't.
