Abstracts: The accumulation of dust on the surface of photovoltaic module decreases the radiation reaching the solar cell and produces losses in the power generated. Dust not only reduces the radiation on the solar cell, but also changes the dependence of such radiation. Therefore the daily energy loss along a year caused by dust deposited on the surface of the PV module. In long periods without rain, daily energy losses can be higher than 20%. In addition the irradiance losses are not constant throughout the day and are strongly dependent on sunlight incident angle and the ratio between diffuse and direct radiation. Due to this reason increasing losses and reduces power generation. So that in solar power plant to reduces losses and increasing power generation we apply a system which is remove or clean dust on solar cell. In this project we have to using spray of water and wiper which are used to remove or clean dust on solar cell. And result of this more sunlight is reach to surface of photovoltaic module. So power generation is increasing & it is improve the efficiency of solar cell.
