Abstract: A robot for cleaning solar panels has a frame and a propulsion system for moving the robot on solar panels. The robot also has arms movably coupled to the frame, and a cleaning assembly coupled to each of the arms for cleaning the solar panels. The arms and cleaning assemblies further facilitate the transportation of the robot between solar panels that are discontinuous and spaced apart from each other. In addition, a water distribution system is included for distributing water during cleaning operations. A control system operates the robot and controls the propulsion system, arms, cleaning assemblies and water distribution system.
