10-Day Rain Guarantee

Norco solar arrays get dirtier, faster, than almost any rooftop in Riverside County. Dirt trails instead of sidewalks, arena sand, and dry-lot decomposed granite mean there's always fine grit in the air, and it settles straight onto panel glass. A dusty array quietly loses output every month it goes uncleaned. Blue Ribbon cleans Norco solar with soft brushes and pure deionized water that rinses spot-free and leaves no residue for the next dust cloud to stick to.

Local conditions
Horse trails, arenas, and dirt roads keep fine granite dust airborne year-round — Norco panels re-soil faster than in-town rooftops.
Grit bonds with sprinkler and irrigation overspray into a cemented film that light rain can't rinse away.
Ranch homes are mostly single-story with wide, low-pitch arrays that hold dust rather than shedding it.
Bird and barn-swallow activity around outbuildings leaves droppings that bake onto panels in inland summer heat.
Systems sized tightly to a large-lot property's usage show soiling losses on the bill quickly.
