A multi-purpose cleaning system for cleaning glasses/stickers/solar panels is disclosed. The disclosed cleaning system is based on a housing movably arranged on an object to be cleaned; cleaning elements to clean the object; rotary devices to enable movement of the housing across the object to facilitate cleaning of the object; a control unit configured to actuate the rotary devices; and a spring mechanism operatively coupled to the rotary devices. The spring mechanism is configured such that the spring mechanism either gets compressed or extended when the rotary devices are actuated to move the housing to clean a cleaning area of the object. A biasing spring force of the compressed or extended spring mechanism facilitates movement of the housing from the cleaning area of the object to be cleaned to a rest position on the object.

A solar panel washing assembly for automatically cleaning solar panels includes a plurality of solar panels that is each positionable on a support surface to be exposed to sunlight. A fluid supply pipe is fluidly coupled to a pressurized water source w to receive pressurized water and a control unit is positioned proximate the support surface. The control unit is fluidly coupled to the fluid supply pipe to receive the pressurized water. A plurality of distribution pipes is each fluidly coupled to the control unit to receive the pressurized water when the control unit actuated into the open condition. A plurality of spray nozzles is each fluidly coupled to a respective one of the distribution pipes to spray the pressurized water onto a respective solar panel to clean the respective solar panel.

An image/video capture apparatus is provided, to capture image data of a photovoltaic panel (101) and surroundings, and a controller (502) recognizes a category corresponding to the image data, and generates different instructions to control rotation of a photovoltaic tracker (102), to remove dust or snow accumulating on the photovoltaic panel (101). This does not need continuous heating, but is simple and efficient, saves electric energy, and resolves a technical problem that a conventional snow removal method of heating has low efficiency and wastes electric energy. In addition, a corresponding controller (1200) is further provided.

A drive track for a cleaning robot moving on inclined surfaces such as photovoltaic panels has a multilayer structure comprising: an internal layer formed by a continuous belt having an internal face able to engage with means for driving the track; an intermediate layer including a plurality of damping blocks disposed over the entire length of the continuous belt of the internal layer with a predefined separation (e); and an external running layer coming into contact with the surface on which the track moves, the running layer being formed by pads supported by the damping blocks. The damping blocks are made of elastomer material and have a cellular structure with a plurality of parallel trough-channels.

SYSTEM FOR CLEANING SOLAR PANELS. A system 100 for cleaning solar panels 304 arranged in a row includes a frame 102, rotating members 106 and a stationary brush 110. The frame 102 moves along the row of solar panels 304. The rotating members 106 interfaces with surface of the solar panel 304. An axis of rotation of the rotating members 106 is incident at an angle to the solar panels 304. The plurality of rotating members 106 are connected to the frame 102 to move with the frame 102 along the row of solar panels 304. The stationary brush 110 is engaged to the frame 102. The brush 110 interfaces with the surface of the solar panel 304 to unsettle foreign particles present on the surface of the solar panel 304, as the frame 102 traverses along the row of solar panels 304.

A method and device for attaching and detaching material to a c-channel groove, including attachment and detachment between first and second objects already attached to the groove. The device comprises a coil-shaped element that is resiliently compressible and connected to a desired material. Through biasing, the coil-shaped element is navigable into an aperture of the c-channel groove at a point along the c-channel groove between the ends of the c-channel groove and positionable such that at least a portion of the biased coil-shaped element is in the c-channel groove. Upon restoring the biased coil-shaped element toward a second, larger dimension, it is secured in the c-channel groove and the material connected to the coil-shaped element is attached to the c-channel groove, including between the first object and the second object, if present.
