RST NightWash™ is a fully automated solar panel cleaning system with no moving parts that you can control from your phone. Clean whenever you want and keep your panels clean all the time.
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 onto high voltage rooftops 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.
RST CleanTech was established in 2013 and quickly became a global leader in automated solar panel cleaning. Since our inception, we have installed 4,000+ projects worldwide ranging in size from residential arrays to large-scale utility projects. Today our patented systems clean more than 2,000,000 panels each day.
We hold two patents that allow our systems to deliver water effectively and efficiently with no moving parts. Our technology has been closely inspected by a variety of panel manufacturers who have determined that RST’s NightWash system is not only effective but also meets their panels’ maintenance requirements and specifications.
We have offices in Israel, Spain, Italy, Chile, and the United States and our global team specializes in the solar PV industry and in automated operation and maintenance (O&M) solutions. Our deep industry experience, uncompromising commitment to quality, and expansive geographical reach allow us to maintain our position as a global leader in automated solar panel cleaning.
