Window washers expand to solar panel cleaning
According to the story, several companies — including maker of high-reach poles Mr. LongArm and window cleaning supplier J. Racenstein Co. — demonstrated products and techniques for cleaning solar panels at the convention, and many business owners expressed interest in offering the service to their customers.
Manufacturers of solar panels often require cleaning to keep warranties valid, and power efficiency of the panels can be adversely affected by up to 40 percent when the panels are dirty, the story stated.
Steve Blyth, vice president at J. Racenstein, said: "We have people who get rebates from Southern California Edison for systems on the roof of their manufacturing facility, and all of a sudden the rebate stopped entirely because they didn''t hit the minimum threshold for power output. This was probably a $3,000-a-month rebate, so cleaning is a nominal cost when you lose that kind of rebate."
