Solar Panel Cleaning Robots for Commercial

An autonomous robotic cleaning system for solar installations, powered entirely by water pressure. The robot moves across the panels and cleans them in a single pass using nothing but mains water. No electricity reaches the panel surface.

Over 800 robots operate at customer sites today across Israel (including Neve Ur, Kvutzat Yavne, and Tirat Zvi). Solaris has 25 years of operational experience, 5 registered patents, and active partnerships in India (V5C) and the UAE (Macradiant).

Three things: It is driven entirely by water pressure (no electrical motors or wiring on the panel), it is rail-free (rides directly on panel frames), and the same platform serves all segments, including agri-voltaic and floating PV where competing systems cannot operate.

Mains water enters at 3 to 3.5 bar. A patented water motor converts that pressure into mechanical motion to drive the robot and rotate the cleaning brush. The water that has done its work then exits and washes the panel surface, removing 99.5% of dirt.

Each robot carries a battery-powered Remote Terminal Unit (RTU) operating four electric valves. A site Gateway communicates with all RTUs over RF (166-176 MHz) and connects to the cloud via cellular for remote control and monitoring via an app or dashboard.

Each robot lives at a Docking Station at one end of the row. It uses magnets to stop precisely on return, with an additional mechanical stop as a safety backup. Homing happens automatically after every cleaning cycle.

Rooftop C&I, ground-mount fixed-tilt, trackers, agri-voltaic sites, and floating PV. The robot adjusts to any panel width on framed modules, supporting single-, double-, and triple-row layouts up to 100 meters per robot.

No. Trina Solar and GCL have confirmed in writing that Solaris does not void module warranties. Furthermore, it has been independently certified by PI Berlin to operate for 25 years of equivalent cycles without damaging the anti-reflective coating.

Regular cleaning eliminates soiling losses, recovering up to 25% more energy with a typical payback period of 24 to 48 months. For example, a pilot at Neve Ur delivered an 18% average yield increase and reached full ROI in 3.4 years.

1.5 liters per meter of robot travel. A 1 MW site with single rows uses about 3.75 cubic meters per cycle, and double-row layouts cut that in half. Standard mains water works for almost every site; no deionized water is required.

It requires a single-phase 20 amp power source for the operating cabinet and a water supply network (minimum 2.5 m³/hour at 1 bar). Maintenance is minimal: the RTU battery lasts 3 to 5 years, and brushes are replaced on a cycle-count schedule.
