چکیده

if  dust settles on solar panels, it greatly reduces solar energy efficiency and is economically detrimental.; For this reason, the viability of photovoltaic power in smart grids is threatened. The power supplied by a photovoltaic module depends greatly on the amount of irradiance reaching the solar cells.. There are a number of factors that determine the optimal performance of a PV module. But the environment is one of the parameters that directly influences photovoltaic performance. In this article, we examine the factors that reduce the efficiency of solar panels. We also describe various solutions for removing dust sitting on photovoltaic panels to the output power of the panel to reach the highest level. The electrical properties of photovoltaic (voltage and current) in relation to the shadow caused by dirt are discussed.. Pollution on panels is divided into two categories, light shadows such as air pollution and hard shadows that occur when a solid such as dust prevents sunlight from reaching part of the panel.. Increasing dust on the surface of solar panels reduces the amount of sunlight reaching the photovoltaic panel cells.therefore, the efficiency of the solar panel is severely impaired. To maximize their ability, they must be cleaned periodically, usually with water. Of course, water desalination devices can also be used to provide the water needed to clean solar panels. Solar photovoltaic technology can have a significant impact on the industry, agriculture, and domestic consumption in reducing fossil fuel consumption and reducing environmental and air pollution
