"The RST system was more effective than we originally thought. We have had it operating for 4 months now – we were surprised how clean it has kept the panels with zero effort or hassle for us. It has required no maintenance and we can control the entire system from our phone. It has been great to see our panels looking clean and productive everyday."

"Our Calabasas office building has a great location in terms of freeway access and visibility, but that also translates into heavy soiling. Washing quarterly just wasn’t keeping production up where we wanted it. With RST, we’ve witnessed over 20% increase in production so far. I plan to include it in any future solar installations."
