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.

1. Method for controlling a flying body for cleaning surfaces

2.1. Flying bodies can cover large distances between arrangements of smooth and curved surfaces without requiring manual manipulation. This reduces personnel requirements and enables large surfaces to be maintained, for example solar power stations, in a fully automated manner.

2.2. The method for controlling a flying body for cleaning surfaces consists of detecting the surrounding surfaces of an object to be cleaned, directing the flying body with respect thereto and structuring the flight path. As a result, the surface can be cleaned particularly efficiently and, if needed, worked on further.

2.3. Said method for controlling a flying object for cleaning surfaces is suitable for use on glass facades or on solar power stations, particularly in arid regions.

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.
