Photovoltaic modules accumulate dust and dirt on their surface when exposed to the weather. This deposited dirt decreases the performance of the photovoltaic systems due to the reduction of the irradiance that reaches the solar cells of the modules. Such losses depend on the local weather conditions, the characteristics of the installation and the surroundings where the system was installed. A way to quantify the impact of these losses is through the soiling rate, a dimensionless quantity that represents the difference between the real (dirty) and expected (non dirty) output power of the system. This work presents an evaluation of the soiling impact on an experimental photovoltaic system composed of five 245 WP crystalline silicon modules installed at the Solar Energy Laboratory of the Federal University of Rio Grande do Sul in thr city of Porto Alegre.
