Charles Vanderkooi of Riverdale, California used RST to increase the production of his solar panels. He was previously paying to have his panels cleaned once a month.
Over the course of this case study, RST improved energy production by 13% on average. That is 13% better than the previous year where the owner was paying to have his panels cleaned once a month. In other words, even with monthly panel cleaning, the owner was still losing roughly 13% energy production each month due to the dirt accumulating on his panels between cleanings.
RST CleanTech installed the RST NightWash™ system – an active cleaning solution (ACS) – on a 1.1 MW single axis tracker system located in Riverdale, California in May of 2022. The installation took only 3 weeks. RST pulled off working with a 2” water pipe near the dairy and used a standard electrical plug from the weight station to run the entire system.
This customer was paying to have his panels cleaned every month and was losing out on a significant amount of energy and thus revenue. What about your system? Regardless of frequency, there’s a good chance that you’re overpaying for manual panel cleanings that leave your system still underperforming expectations. This can be easily avoided.
No one should settle for looking at dirt-covered brown panels. Stop waiting for the panel cleaner to arrive, keep your panels blue all the time with RST NightWash™!

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.
