Panel soiling in La Grange is mineral as much as dust, because the sprinklers reach the array. It sits in Boise south of Amity, between Cloverdale and Five Mile in 83709, and it is older than most of the city around it — recorded 1914–1915 on one plat. It covers about 323 acres, large enough that we route it as its own stop.

A solar panel is a piece of glass mounted at a shallow angle with nothing above it, which makes it the best dust collector on the property. Here it catches decomposed granite off the foothills, plus the winter inversion that traps particulate at ground level for weeks at a time, and then — the part people do not expect — it catches irrigation overspray. Untreated water on a warm panel evaporates fast and leaves exactly the bonded mineral film it leaves on windows, except here it sits directly in the light path. The panels at the low edge of the array, where runoff concentrates, are usually worst. Across about 323 acres the pattern barely varies here.
Panels get the same pure-water method as glass, for a better reason: soap residue on a panel is a soiling magnet, so a soaped panel gets dirty faster than one never cleaned. Deionized water dissolves the mineral and dries clean. We never use abrasives or anything that could mar the anti-reflective coating, we clean from the ground with poles wherever the pitch allows, and we do not walk on panels — micro-cracking from foot traffic is invisible and permanent. We do not touch wiring or inverters. On La Grange homes of this vintage we check condition before method, every time.
Boise glass carries something the rest of the valley does not: foothills grit. Decomposed granite off the slope is sharp and fine, it travels on the afternoon downslope wind, and in winter the valley inversion holds everything else down at ground level with it. That is the honest reason we push timing as hard as we push method: doing this work at the right point in the Boise season is worth more than doing it more often at the wrong one. La Grange routes off Amity, so getting here is not a special trip.
We clean the glass. We do not touch wiring, inverters or mounting hardware, we never walk on panels, and we will decline an array we cannot reach safely. Reflekt has been operating since April 2025, which is a shorter history than some of the companies you may be comparing us against. We would rather you knew that up front.
Most La Grange customers book this alongside window cleaning. Partly that is price, partly sequence — washing walls after cleaning glass puts dirty water back on clean panes, and hanging lights before clearing gutters means working around your own strands in January.

On a visibly soiled array, yes — meaningfully. On one cleaned two months ago, not really. We will look and tell you honestly if it does not need doing yet.

Quoted per array. The final number depends on the property, and there is no contract and no membership requirement. Booking it alongside another service on the same visit is the cheapest way to do it.
No abrasives, no soap, and nothing that touches the anti-reflective coating aggressively. Pure water and soft media only.
We avoid it, and we never walk on panels. Most arrays we reach from the ground with poles. If yours cannot be reached safely we will say so.
