A solar array in Riverstone loses output to something specific. uneven organic film on the water side plus construction fines, which cost more output than plain dust does.
Arrays here deal with two things at once. Humidity off the beach and lake keeps organic debris stuck to the panel rather than letting wind clear it, and that film dries patchy — which costs disproportionately more output than uniform dust, because a partly shaded cell drags down every cell wired in series with it. Meanwhile nearby construction puts gritty alkaline fines on the glass. Both get flooded off with pure deionized water before anything touches the surface.
Estate elevations put arrays on steeper pitches and higher planes than a single-story home, frequently across several roof faces with different orientations. That means the reach rather than the panel count is usually what sets the number, and it means nobody should be walking a steep array field to save time. We work out the approach at the quote — pole-fed pure water from the ground where the geometry allows, proper roof access only where pitch and footing honestly permit.
Enough to matter on a genuinely soiled array, and we will give you the real version rather than a number we cannot stand behind. Uniform dust costs a few percent; a bonded mineral or organic film costs more because it shades unevenly. If shade from mature trees or an adjacent structure is what is limiting your output, cleaning will not fix that and we will say so. Arrays are quoted per array, with pure deionized water and no soap.
Arrays are quoted per array after a look at the roof, because reach rather than panel count usually sets the number. Every wash is 100% pure deionized water with no soap — soap residue on panel glass attracts the next round of dust and can raise a question with your installer, so there is nothing to gain from it. On a gated lot we ask for a code or a call-ahead at booking so the crew is not sitting at the entrance.

Because panels are wired in series. A uniformly dusty array loses a predictable few percent, but one shaded or filmed cell drags down the whole string around it. That is why blotchy organic film costs more than it looks like it should.
Enough to matter on a soiled array, and we will give you an honest answer rather than a number we cannot stand behind. Uniform dust costs a few percent; a bonded or patchy film costs more because it shades cells unevenly. If shade rather than soiling is limiting your output, cleaning will not fix it and we will say so.
No — 100% pure deionized water and nothing else. Soap residue on panel glass attracts dust and can raise a warranty question with your installer, so there is nothing to be gained by it.
You can, and it often backfires. Eagle's water is hard, so a hose rinse dries into a mineral film that shades cells about as well as the dust did. Worse, hosing does not lift grit — it redistributes it, and anything then brushed is abrasive on glass you cannot replace cheaply.
Yes — Eagle is one of our nine Treasure Valley cities and we run it as a regular route rather than a stretch call, from the Chinden edge up into the foothills. Call or text (208) 453-6760 and we will tell you the next open slot.
Our 7-Day Rain Guarantee covers it. Rain on a clean surface is largely harmless — it is the dust it lands on that spots. If a storm genuinely undoes the work inside seven days, we come back out.
