Solar panel cleaning in MetroWest, MA
Panels only make power from the light that reaches them. Spring pollen, road dust and bird droppings all sit between the sun and your system.
quoted per system · Pricing depends on how many panels you have and how they're laid out, so every system gets its own quote.
Solar panels are self-cleaning in theory. Rain handles the light stuff. What rain doesn't handle is the yellow pollen film every spring, bird droppings, or the grit that builds up along the bottom edge of each panel where water sits and dries.
We clean panels the same way we clean glass: pure water through a water-fed pole, no harsh chemicals, no scrubbing at the surface. Pure water dries without leaving spots, which matters on a panel you're not going to wipe down afterward.
What you get
What's included
Roof-mounted panels
Cleaned from the ground with a water-fed pole where the layout allows it.
Ground-mounted arrays
Easier access and usually quicker.
Pure water, no harsh chemicals
Water only, so nothing gets left on the glass and nothing runs into your landscaping.
Edges and frames
The grit line along the bottom edge of each panel gets cleaned, not just the middle.
Panels left to dry spot-free
Pure water means no mineral spots when it dries.
Why panels lose output
Panels convert the light that reaches the cells, so anything sitting on the glass blocks some of it. Rain handles light dust, which is why panels get described as self-cleaning, but rain doesn't remove a bonded pollen film or bird droppings, and it can't clear the grit line that builds along the bottom edge of each panel where runoff collects and dries.
If your system has monitoring, the easiest way to see it is to compare a clear day this month with a clear day right after the panels went in.
How we clean panels
Pure water through a water-fed pole, the same setup we use on glass. The water is filtered so there are no dissolved minerals in it, which means it dries without leaving spots. Nothing to wipe off afterward and nothing running into your landscaping.
No harsh chemicals and no abrasive pads, because panel surfaces have coatings that scratch. We work from the ground wherever the layout allows.
How it's priced
Pricing depends on how many panels you have and whether they're roof or ground mounted, so every system gets its own quote. Ground-mounted arrays are usually quicker and cost less than the same number of panels on a roof.
Most systems around here do fine with one cleaning a year, usually right after pollen season. If you're near a farm or a dirt road you may want it twice.

FAQs
Questions people ask
Don't see yours? Text us at (508) 978-5026.
Does cleaning panels actually matter?
Panels make power from light that hits them, so anything blocking the surface costs you output. Pollen season and bird droppings are the big ones around here.
Do you use soap or chemicals?
No. Pure water through a water-fed pole, which dries without leaving spots.
Will you walk on my roof?
We work from the ground with poles wherever the layout allows.
How often should panels be cleaned?
Once a year suits most systems around here, usually after pollen season.
Can you do my windows the same day?
Yes, and it's the same equipment, so it's worth booking together.
