We clean Princeton solar panels with pure water and soft brushes so they make the power you paid for.
The question we get asked most is whether you can just pressure wash them. You should not. A solar panel is glass bonded over a laminate with an anti-reflective coating and a perimeter seal, and pressure is the one thing that finds all three. We wash them with deionized water and soft brushes, at a pressure a garden hose would beat.
You do not have to guess whether this is worth it, because the array already tells you. Pull last spring's production against this spring's on the app. If the curve has dropped and nothing has changed but time, what is on the glass is the difference.
Panels are self-cleaning right up until they are not. Rain handles light dust. It does not handle pine pollen, bird droppings, or the film that builds up under a tree line. Those are what quietly cost you production.
This is the point where a wash is still cheap. Past it you are looking at repair instead of cleaning.
Clearing buildup helps the array last.
Fed poles reach most residential arrays, so we keep weight and footsteps off the roof.
Pure water and soft brushes only, so nothing degrades the coating.
Clean glass lets the panels produce what they should.
Clean after the pollen drops and the production curve makes the case for itself.
We confirm access and panel condition.
Deionized water loosens pollen and dust.
We clear the film without scratching the glass.
A pure-water rinse dries spot-free.
Solar cleaning in Princeton prices per panel, with roof pitch and access as the other two factors. Ground-mount arrays are the cheapest to service. Steep roof arrays cost more because of the setup.
We have been cleaning Princeton, in eastern Johnston County, since 2010. It is in Johnston County and it is on our regular run.
Recurring beats reactive on a commercial property, and it costs less per visit. We set an interval that suits your traffic, keep a dated record of every visit, and stay out of the way of your customers while we do it. Fully insured, HUB-certified, invoiced on terms.
“Did the roof and the gutters in one visit and showed me photos of everything I could not see from the ground.”
“The black streaks on our roof were embarrassing. Gone in one afternoon and the shingles were not touched.”
“They brought the color back on our vinyl siding after another company left it chalky. Night and day.”
We fly the roofline and show you the footage on the spot. You see your own gutters, joints, and downspouts on the screen instead of taking our word for it. It costs nothing and you are not committing to the cleaning.
Free for homes and businesses across the Triangle and Johnston County. No obligation to book any work afterwards.
