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.
