A photovoltaic-module cleaning robot, an obstacle-surmounting method and device thereof are provided according to the present application. If the photovoltaic-module cleaning robot gets stuck during obstacle-surmounting, a lower end motor of the photovoltaic-module cleaning robot is controlled to operate reversely, so that the lower driving wheels thereof rotate reversely; an upper end motor of thereof is controlled to stop operating, so that the upper driving wheels thereof have no drive; and then, the photovoltaic-module cleaning robot is gradually restored to a horizontal state, and if it is determined that the photovoltaic-module cleaning robot meets a forward moving condition, the upper end motor and the lower end motor of the photovoltaic-module cleaning robot are controlled to simultaneously rotate forward to realize moving forward, thereby solving the problem of easily getting stuck at a drop height between adjacent modules.

An obstacle crossing mechanism, adapted and arranged on a cleaning rack of a photovoltaic panel cleaning equipment configured to clean photovoltaic panel arrays is disclosed. The cleaning rack includes connecting rods detachably-connected, and fixed rods arranged on respective connecting rods. The obstacle crossing mechanism includes a moving rack and a fixed rack, in which moving rack is used for temporarily stopping photovoltaic panel cleaning equipment; and the fixed rack is located below the moving rack and the moving rack ascends or descends on the fixed rack. A telescopic mechanism is further provided with the obstacle crossing mechanism so that the two mechanisms together facilitates the photovoltaic panel cleaning equipment to travel from a photovoltaic panel array to reach another photovoltaic panel array during cleaning process of photovoltaic panels without requiring any human assistance, thus achieve total automation.

An Automatic (Auto) Photovoltaic (PV) Solar Panel Washer comprising a main carrier joined by a connecting member to the main mast. A main hydraulic cylinder system comprising one or more hydraulic cylinders and connector arrangement on the main mast raises the main mast up or pushes it down, activating the connecting member, thereby raising or lowering the main carrier. The positioning hydraulic cylinder determines the angle of the main carrier by pushing one end down or bringing it up. A rotating device assembly rotates the main mast and main carrier clockwise or counterclockwise from rest position over its stationary post. The main carrier comprises a rigid frame with attachments including a cleaning assembly consisting of air cylinders with cleaning wiper systems, tracks for the air cylinder shafts, wash material pipes with spray devices attached, rinse material pipes with spray devices attached, and compressed air drying pipes with air spray devices.

A method and device for cleaning and pretreating solar panels is provided. The device comprises a brush having cleaning elements made from silicone foam rubber material. The cleaning elements can be flaps of silicone foam rubber material. A sheet of silicone foam rubber material having two free ends can be attached to a core member such that the two free ends extend away from the core member to form flaps. The solar panels can be cleaned by brushing the solar panel surfaces with the flaps of silicone foam rubber material. The solar panels can also be pretreated by brushing the solar panel surfaces with silicone foam rubber material.
