Installers: Deliver on your maintenance-free solar promise.

Your residential customers are more solar-savvy today than ever before. They know dirty panels equal lost production and energy savings. And when a “maintenance-free” system produces less than expected, it can reflect poorly on the installer. Some customers will resort to climbing on their roof or spraying their garden hose to remedy the issue, but this can actually damage the system. 

The answer is a simple solution. Our fully automated solar panel cleaning system, RST NightWash™, keeps production high and your customers happy. We use advanced water filtration technology to wash solar panels with pure, low pressure water to protect warranties and optimize production. 

RST works with installers to provide this automated cleaning solution either at the time of sale or as a retrofit application. Increase the value of your installations while providing a higher performing product for your customers.

"We have had RST on our solar panels for over a year now. Our roof is steep, and previous cleaners were tearing up the shingles. The cleaners also made me nervous with unnecessary risks – I don't want anyone to get injured at my house. And because of the steep roof, our neighbors can easily see our panels. I love that my panels are always a clean black, especially since we are next to the freeway. The neighbors ask how I keep them so clean! Best of all, our true-up bill has basically been eliminated due to RST. I would highly recommend RST."
