What we do

Your panels are losing power to grime right now

Pollen, dust, bird droppings, and hard water quietly block the sunlight your system was built to capture. We remove all of it with soft brushes and de-ionized water, then prove the difference with inspections and before/after documentation.

What we offer (4)

Four lines of work, one careful method. Every cleaning includes a visual inspection at no extra charge.

Commercial experience

Commercial-scale work, documented

We clean arrays most residential-only companies will not touch. Two examples:

Rows of panels running to the horizon on a large flat commercial rooftop

2,700-panel rooftop array

Flat commercial rooftop, cleaned with pure de-ionized water and documented with before and after photos.

A vast ground-mount solar array with rows stretching toward forested hills

1,904-panel ground-mount array

Large ground-mounted system cleaned row by row with water-fed poles and soft brushes.

Proof, not promises

Drag the line. See the difference.

Harsh brushes scratch glass. Hard water leaves mineral film. Our de-ionized water system lifts grime and dries spot-free, with zero chemicals touching your panels, roof, or garden.

One customer reported higher production readings on their own monitoring app after a single cleaning. Every job is documented the same way, with before and after photos. Results vary with buildup, shading, and conditions, and the documented numbers are on our results page.

No. Rain rinses loose dust but leaves pollen film, bird droppings, and mineral spots bonded to the glass. In the Portland metro, panels still lose efficiency between storms. A de-ionized water cleaning removes what rain cannot and dries spot-free.

Once a year is the right baseline for most Portland-area homes, ideally after spring pollen season. Arrays near trees, highways, or farmland benefit from a semiannual schedule. We recommend a plan after seeing your specific site.

We use soft, panel-rated brushes and pure de-ionized water, with no harsh chemicals and no abrasive pressure. This is the approach panel manufacturers recommend for routine maintenance.

Every quote is free, in writing, and based on your panel count, roof pitch, and access. Residential pricing scales with array size; commercial work is quoted per site. Request yours and you will have an exact written number before any work begins.
