Everything people ask before booking

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.

It depends on buildup, shading, and conditions, so we never promise a fixed number. Pollen, dust, and droppings quietly cost most systems a measurable share of output every year. We document the difference with before and after photos, and one client’s monitoring data is published on our results page.

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.

De-ionized water has its minerals removed, so it absorbs grime and dries without spots or streaks. Tap water leaves mineral deposits that scatter light and create new film on the glass. Pure water is the professional standard for solar glass.

No. Our cleaning is chemical-free: pure de-ionized water and soft brushes only. Nothing harsh touches your panels, your roof, or your landscaping, and nothing is left behind.
