About

Solaris Hydrobotics develops and offers autonomous, water-powered robots designed for cleaning solar panels in agricultural fields, commercial rooftops, small solar farms, and floating PV systems. Their innovative, patent-pending technology uses water to power the robotic cleaners, rotate the brushes, and wash away dirt. With no need for electrical motors or expensive infrastructure, their autonomous robots provide a cost-effective, sustainable solution that makes regular panel cleaning both affordable and efficient. The company's foundation rests on a breakthrough in hydraulic engineering—Ehud Nagler's invention of a high-torque, low-pressure hydraulic engine. Solaris systems are engineered to maximize total energy yield, extend asset longevity, and significantly reduce Operations & Maintenance (O&M) costs. The company also offers an all-in-one cloud-based control center for remotely managing, maintaining, and optimizing solar panels.
