A solar panel cleaning system includes: an automated cleaning device for cleaning a surface of a reference cell panel; a cleaning device controller in communication with a motor of the automated cleaning device, the cleaning device controller configured to receive a signal corresponding to measurement of a current of photovoltaic system. The cleaning device controller activates the automated cleaning device to clean a surface of the reference cell panel when the received signal indicates that a measurement of the current of the photovoltaic system is to be taken.

A solar panel cleaning apparatus includes at least two rails in which a fluid pipe moves over the surface of a solar panel and sprays a fluid onto the surface of the solar panel in order to remove dust, dirt, film and debris. Nozzles are part of the fluid pipe which sprays the fluid on the surface of the solar panel. Each rail includes grooves along a surface of the rail and wheels are propelled along the grooves the rail. A fluid conduit is attached to at least one wheel within one of the rails and is in fluid communication with the fluid pipe. A self-aligning bearing is connected to the wheels to keep the fluid conduit from winding around itself or the wheel. Humidity and wind sensors control the start and stop of a pump.

A travel path is arranged on the end faces of the solar panels and on which a service robot can travel, can rotate in place by a suitable rotational device, and can continue on a line. In this manner, the service robot can travel completely autonomously. For each row of adjacent solar panels, a centering opening is paired with the travel path, wherein the service robot has a centering pin which can engage into the centering opening, or the travel path is made of multiple sub-surfaces which form a respective rotary table in the region of the end faces of the solar panels, and the rotary table can be rotated about a perpendicular rotational axis running through the rotary table.

A docking station for use with a solar tracking system includes a frame configured to selectively support solar cleaning equipment thereon and a mounting bracket operably coupled to a portion of the frame. The mounting bracket maintains a gap between adjacent edges of the frame and an adjacent solar module, and the frame includes a width that approximates a width of the solar module.

Systems and methods for autonomous drone-based solar panel maintenance may utilize drone positioning, image analysis, and processing to determine solar panel angle and clarity.

The present invention relates to self powered and timer based solar panel cleaning system that is operated by self generating electrical power from solar energy and reduces wear and tear problem of moving parts. In this system, the microcontroller (54) is interfaced with motor driver (51) and brush driver (52). Said motor driver (51) and brush driver (52) control the speed of wheel motor (32) and brush driver (33). When ultrasonic sensor (5) sends signal to microcontroller (54), said microcontroller (54) generates and transmits signal to wheel motor driver (51) and brush driver (52). Thus, when structure reaches nearby the end edge of the solar panel array, said drivers gradually reduce r.p.m. of wheel motor (32) and brush motor (33) and then motors stop when machine reaches to opposite platform. Thus, during alteration of mode, r.p.m. of motors will be at substantially low that prevents the moving parts from damage.
