Análise da influência da temperatura na eficiência de geração de sistemas de energia solar fotovoltaica com otimizadores de potência

Abstract

Since the beginning of time, energy has been indispensable for the maintenance of life. With modern times and the advent of new technologies, society has become dependent on electrical energy. Due to the high demand and high levels of pollution from fossil fuels, the search for renewable energy sources has grown, one of them being photovoltaic solar energy. This, in turn, has some technologies present on the market today, with emphasis on traditional inverters and systems with power optimizers. Knowing that the generated energy depends on the solar incidence, which, the higher it may be associated with places with higher temperatures, the present work aims to analyze the influence of temperature on the generation efficiency of photovoltaic solar energy systems with power optimizers. To this end, two plants from different locations in Brazil were chosen, one in the Northeast and the other in the South, with similar powers and equipment, which will have their generation and temperature values compared. It was observed through the analysis that the losses may be more associated with climatic factors, such as rain and cloudy days; and that, therefore, the temperature does not generate significant losses in systems with power optimizers.
