Análise de redução da eficiência em módulos fotovoltaicos policristalinos

Abstract

The generation of electrical energy through photovoltaic systems has played an increasingly important role in the global energy scenario. However, some challenges still persist, especially in relation to the durability of the photovoltaic modules. Several factors lead to its degradation, leading to a progressive reduction in its efficiency over the years. In general, the degradation may differ according to the type of photovoltaic technology used and the environment where the modules are installed. Thus, this work aims to investigate the degradation conditions in efficiency in photovoltaic generation projects in the city of Cornélio Procópio-PR in the period between 2017 and 2020, making it possible to verify the data according to the manufacturing specifications of the equipment used. The results validate the manufacturers' data for most of the systems investigated over the four years, maintaining a minimum efficiency of 90%, with efficiency losses of around 3%. Future works of comparison between monocrystalline and polycrystalline panels are proposed.
