WebOct 28, 2024 · Solar photovoltaic (PV) deployment is rapidly expanding around the world. However, the soiling factor has an impact on its performance. Saudi Arabia has high solar irradiation and plans to diversify its energy mix for electricity generation by deploying more solar PV across the country. However, it is located in an arid and desert environment, … WebFigure 31. Example Soiling Loss by Month . These loss factors are then translated into a soiling loss factor, or “soiling ratio”, μ dirt,t which is a fraction close to unity, and is the complement of the soiling loss percentage. For example, a loss coefficient of 0.99 corresponds to a 1% loss of irradiance due to soiling on the modules. Inputs databasedll_finalrelease
