Solar Panel has a huge effect on our world. It can help our environment to be better without using other power generation plants that can harm the environment, but solar power plant needs to be cleaned regularly. If the solar panel is not cleaned regularly, then the dust in environment accumulates on the surface of the solar panel. This dust converts into a thick sticky layer due to morning dewdrops. Due to this dust, the efficiency of the solar panel decreased. In this project, we design a cleaning system for a solar panel which can be operated automatically and it helps us to clean solar panels without any efforts. This system reduces human efforts, it saves time, and it works automatically. Overall it increases the efficiency of the solar panel. The cleaning is achieved using a water-based Roller brush. Two ac motors with inverters are used for the brush and the system’s assembly motions. A control unit based on Arduino is built to perform the cleaning task with the aid of limit switches, relays, electric valves, and other electrical and electronic tools. The brush is attached to the moveable assembly of the system. This brush remains in contact with the panel. When the assembly of the system moves, water flow through sprinkles on panels and brush move on the surface of the panel and removes the dust. The proposed system is tested and evaluated by comparing the electrical parameters (maximum power, voltage, and current) for the solar panel before and after cleaning. Results show that the efficiency is increased when the solar panel is regularly cleaned.
