Solar Panel Cleaning done properly in Centennial

Centennial has one of the higher rates of residential solar in the south metro, and most of those arrays have never been cleaned. Dust, spring pollen, and tree litter build a film that costs real production long before anyone notices it from the yard.

We use deionized water and a soft brush — no detergents, no pressure, nothing that risks the anti-reflective coating on the glass. Most Centennial arrays can be reached with a pole from the ground.

What makes Centennial different

Tree canopy means sap and leaf tannin, not just dust

Arrays under mature maples and ash pick up sticky sap and tannin staining that plain rinsing won't lift. That needs dwell time with pure water and gentle agitation.

Low winter sun angle magnifies soiling losses

In December and January the sun is low and your production window is short. A dirty panel costs proportionally more in winter, which is why a fall clean pays back faster than a spring one for a lot of Centennial homeowners.

Mostly ground-reachable single-story arrays

Many Centennial homes are ranches or split-levels, so we can pole-clean the array without rooftop access. That keeps the price down and keeps weight off your roof and racking.

Solar Panel Cleaning in Centennial — common questions

How much does solar panel cleaning cost in Centennial?

About $8 to $15 per panel with a service minimum. Single-story arrays we can reach from the ground come in at the lower end of that range.

How often should solar panels be cleaned in Centennial?

Once a year for most homes, twice if your array sits under trees or near open dirt. Fall is the higher-value visit because winter production hours are short.

Does rain clean the panels for me?

Not really. Colorado rain is usually light enough to dry into a spotted mineral film, which can leave panels dirtier looking than before.

Do you have to get on my roof?

Only if there's no safe way to reach the array from the ground. Most Centennial single-story arrays are pole-cleaned with nobody on the roof.
