Every Detail Solar cleans commercial solar arrays across Nevada, the driest state in the country, where alkaline desert dust and hard water create a severe, low-rinse soiling environment that only pure-water cleaning fully resolves. In Nevada there is no rain to fall back on - if you're not washing, you're losing output, and if you're washing with the wrong water, you're just moving spots around.
Nevada's soiling story: alkaline dust with no rinse
- Playa & desert dust. Nevada's dust is often alkaline and mineral-rich, lifted from dry lakebeds and arid soils. It's chemically stickier than ordinary dirt and cements onto glass over a long dry season.
- Almost no rain. Nevada averages the lowest precipitation of any U.S. state, so natural rinsing is effectively zero. Dust accumulates uninterrupted.
- Hard water trap. Cleaning with local hard water leaves mineral spotting that can shade cells - so the wrong wash barely helps.
The U.S. National Renewable Energy Laboratory (NREL) reports average U.S. soiling loss around 3 to 5 percent annually; Nevada's dry desert utility sites sit well above that.
How we clean in Nevada
Deionized, pure-water cleaning is mandatory here - we target 2 to 20 ppm dissolved solids so the surface dries spot-free, versus the 300 to 1,800 ppm in typical hard water that leaves shading residue. For desert utility-scale farms we run robotic-plus-manual programs on a tighter cadence; Las Vegas and Reno rooftops and canopies get matched crews. All on our published pricing methodology.
