The accumulation of dust and other environmental contaminants in the photovoltaic modules, classified as "soiling", results in a decrease at the solar irradiance that reaches the module's semiconductor junctions and, therefore, reduces the generation of electrical energy. In this context, it is relevant to study this factor impact on the performance of photovoltaic systems installed in different regions, so that you can determine the need for periodic cleaning maintenance through a schedule that takes into account the cost and benefit of this action on the final product, which is electrical energy. Therefore, this research work aimed to analyze the effects of the accumulation of dirt on the surface of the modules on the performance of PV systems, in a project located in Santo André, São Paulo, determining the loss of performance in the generation of electricity caused by dust accumulated over a year and ten months of natural exposure, using IxV curves measured in a field work, in a method of comparing dirty and clean references. The result achieved indicated a loss in power of 16.04% soiling associated.
