O impacto da sujidade em módulos fotovoltaicos no desempenho de usinas solares

Abstract

Photovoltaic energy has consolidated itself as one of the main renewable sources in the global energy scenario, standing out for its sustainability and wide applicability. However, the efficiency of photovoltaic modules can be significantly impacted by environmental factors, among which soiling is a major concern. In this context, this study aims to analyze the effects of soiling, such as dust, dirt, and organic residues, on the performance of modules in photovoltaic plants, considering the losses in electricity generation and the operational challenges arising from this phenomenon. Thus, operational data from 42 power plants were analyzed, comparing energy generation in the 30 days before and after the cleaning procedure. The results indicated an average absolute gain of 11.51% and an average relative gain of 12.78% in generation, confirming the relationship between cleaning and performance recovery. The study provides technical subsidies to optimize maintenance cycles and support decision-making in the photovoltaic sector.
