In order to maintain the efficiency of electric power generated by solar panels, those need to be cleaned regularly. This cleaning, if done manually, has its own limitations in the form of uncertainties related to labour force.

It becomes extremely difficult to access the reinzer area, which again would be full of dust and other unwanted particles. Thus; we require to develop a means of cleaning photovoltaic panels (PV panels) or solar panels autonomously in order to maximize the efficiency and energy output from these panels. This device will prevent the loss of electricity generated by the solar panel by keeping it clean.

There is a resting area for Robotic machine on both the side of solar panel array. The machine then travel on panel in the direction set in program. It reaches from one resting area to the other resting area at the end of other side of solar panel array and vice versa. There is a rotating brush on the machine which removes the dust from the panel. There is a timer which enables the daily supply to the machine at that current time.

• Dry-type cleaning system (no water).
• Less space and No extra power consumption.
• Does not require reinzer of water pipes, water tanks, electrical cables to power/charge the robot; it is energy independent.
• Daily cleaning improves production of the solar PV plants, by removing the dust from panels.
• Is suitable for arid areas where water is difficult and desert areas, where due to dust or sandstorms, energy generated is lost to high extent.
• The most cost effective way of having clean solar PV plants as compared to manual cleaning.
• Is simple, strong, reliable, using high quality components and equipments. The PV cleaning robot can be customized and starts from a system with manual operation to fully independent and controlled.

• Automatic timer operated cleaning system.
• Dry cleaning system with modular rotating brushes which do not affect the surface of the photovoltaic panels.
• Uses high quality brushless motors.
• Operational at high temperatures.
• Hybrid PV-battery power system.
• Increased reliability and using only high quality components.
• Approximate time for cleaning 10 PV each 360watt: 5min.
• Travel distance, up to 50 m. (distance can be increased by using solar PV panel in combination with battery).
• Early morning operation can be done so that before sun rises, panel can be cleaned. Moreover the brushes can have longer life.
