Whether you grow almonds or raise dairy cows, work on the farm gets dirty—and your solar panels are no exception.

The RST CleanTech solution will keep your panels clean through dusty harvest seasons, air pollution, fires, and day-to-day grime, without the hassle of scheduling manual cleanings.

Our fully automated solar panel cleaning system uses patented irrigation technology to wash your panels with pure, chemical-free water, making it safe for operation around crops and livestock. Because you can control your cleanings, you can clean whenever you want and keep your panels clean all the time, maximizing solar production.

"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."
