RST CleanTech installed the RST NightWash™ system, an active cleaning solution (ACS), on two inverters-worth of panels on a 1118.48 kilowatt solar array located in Central Valley, California. RST then compared the production of the inverter with the NightWash™ system against other inverters at the site. This pilot study lasted one and a half months.
Based on these results, retrofitting the entire solar array with RST NightWash™ would result in well over $2.1 million in the pockets of the owner over the array’s remaining 22 year lifespan; this figure includes nearly $2 million in additional energy production, as well as the elimination of four expensive annual cleanings that not only fail to address the region's soiling rates, but also endanger voiding the panels’ warranty.

the case study here.Over 10 years ago, we set out to solve one of the biggest problems facing solar – panel soiling. We wanted to find a way to keep panels clean, maximize energy production, protect panel warranties, and increase revenue for system owners.
We knew there had to be a way to achieve our goals that didn’t entail deploying thousands of bristle-wielding workers or robots onto high voltage solar arrays across the world. When we realized there wasn’t, we created one. Enter, RST NightWash™.
RST NightWash™ is a safe, cost-effective, and eco-friendly automated solar panel cleaning solution.
