Revisão sistemática da literatura sobre o impacto da sujidade em módulos fotovoltaicos

Abstract

In the midst of constant industrial development and the concern of seeking for sustainable energy development, studies on renewable energy sources are essential. Solar energy has become the second largest source of energy generation in the Brazilian matrix and many of the studies about it seek to point out the factors that reduce its efficiency and ways to mitigate such factors. Soiling is the accumulation of dust and particulates on the surfaces of panels in photovoltaic systems and is one of the main causes of a decrease in the efficiency of such systems. The present work aims to carry out a systematic review of the literature regarding the impact of Soiling on photovoltaic modules through a bibliographical review of the subject and the analysis of four researches made in different systems in Brazil. All studies carried out data collection in modules before and after manual cleaning, and some of them also analyzed the influence of rain. Based on the data acquired, it was possible to verify the importance of incorporating routine manual cleaning in favor of the increase in the performance of the photovoltaic modules that make up these systems.
