In September 2021, RST NightWash™ was installed on the 836-kilowatt (KW) solar array located on Nunes and Sons Dairy in Tulare, California. Here we look at the impact RST NightWash™ has had in the 7 months since it was installed at this location.
The 836 kW solar array has seen $23,000 of extra production compared to the same period the year before. The system is on track to deliver over $40,000 in extra production for the year.
The value of the extra production amounts to more than the system owner has paid through RST financing, resulting in a net positive cash flow for Nunes and Sons Dairy.
RST NightWash™ is able to deliver drastic production increases with minimal water use. With three cleanings per week at this site, RST NightWash™ requires about the same water needed to irrigate a single almond tree for a year.
"Our RST NightWash™ system has already paid for itself with increased production. It’s a no-brainer investment for our operation. Our solar is producing more than I have paid to RST for the system. The system really doesn’t use much water at all, which is an especially important consideration right now."

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.
