Solar panel cleaning
Pollen on the glass is light your panels never see.
Panels washed and rinsed like glass. No abrasives, no pressure, and the frames cleaned up at the same time.
No grit and no pressure. Panel glass carries an anti-reflective coating, and scratching that coating costs more output than the dirt ever did. A soft pole and nothing abrasive.
A panel only works on the light that reaches it
Solar panels sit at an angle, in the open, under trees, and they collect exactly what you would expect. Pollen in spring, dust all summer, leaf litter and bird mess the rest of the year. Rain moves some of it and bakes the rest into a film.
Anything sitting on the glass is light that never reaches the cell underneath.
The glass gets treated like glass. No abrasives, no harsh solution sitting on the seals, no pressure. It is washed and rinsed, and the frames and the area around them get cleaned up at the same time.
On the roof, carefully
Panels cleaned on a Decatur roof. Reaching them from a pole rather than standing on them.
Panels get walked on far more often than they should. I work them from a pole wherever I can, for the same reason my roof cleaning uses zero pressure: the cheapest repair is the one nobody causes.
If I'm already out for the house or the roof, adding the panels to the same visit is very little extra setup.
Questions I get asked
How often do panels need this?
It depends on your trees and how steep the array sits. A panel under heavy cover collects far more than one in the open. Send a photo and I'll tell you whether yours are due.
Will cleaning damage the panels or the seals?
Not the way I do it. Nothing abrasive, no pressure, nothing harsh left sitting on the seals. They're washed and rinsed like any glass.
Can you do this with a house wash?
Yes, and that is the cheapest way to get it done, because the setup is already paid for by the other work.
Ready for a price?
Tell me roughly how many panels you have and how easy they are to reach.
Most quotes come back the same day. You don't need to be home.
