Este trabalho tem por objetivo analisar o comportamento das perdas de geração de energia elétrica de uma usina fotovoltaica fixada sobre telhados de prédios da Univates - Tecnovates, com potência instalada de 937,12 kWp, bem como, realizar um estudo comparativo com uma usina equivalente instalada em solo com
orientação e inclinação adequadas, utilizando condições climáticas de três fontes distintas. Neste sentido, objetiva-se realizar simulação do sistema proposto a fim de determinar a diferença no montante de energia gerada nos dois casos, estimar perdas, e determinar as eficiências das áreas da usina real. Com base nos
resultados de simulação e uma estimativa de custo adicional, calculou-se a diferença dos ganhos em quatro cenários distintos, relacionando geração real e simulada com a modalidade de mercado livre e mercado cativo. Para as simulações foi utilizado o software PVsyst, além de fazer a validação dos resultados a partir da instalação e monitoramento da geração de dois módulos fotovoltaicos, por 14 dias, com as mesmas configurações utilizadas no software. A medição da energia gerada no protótipo foi realizada por meio de uma bancada de medição composta por transdutores de tensão e corrente continua. Os dados de geração do protótipo foram superiores ao simulado, podendo-se atribuir a diversos fatores. No que diz respeito ao ganho, constatou-se diferenças consideráveis entre os quatro cenários.
This work has the objective of analyzing the losses of electric energy of a photovoltaic plant fixed on roofs of buildings of Univates - Tecnovates, with an installed capacity of 937.12 kWp, as well as to carry out a comparative study with an equivalent plant installed in soil with adequate orientation and slope, using climatic conditions from three different sources. In this sense, the objective is to simulate the proposed system in order to determine the difference in the amount of energy generated in the two cases, estimate losses, and determine the efficiencies of the real power plant areas. Based on the simulation results and an additional cost estimate, the difference in earnings was calculated in four different scenarios, relating eal and simulated generation to the free market and captive market modality. For the simulations, the PVsyst software was used, in addition to validating the results from the installation and monitoring of the generation of two photovoltaic modules, for 14 days, with the same settings used in the software. The measurement of the energy generated in the prototype was carried out by means of a measuring bench composed by voltage and current transducers. The data of generation of the prototype were superior to the simulated one, being able to be attributed to several factors. With regard to gain, there were considerable differences between the four scenarios.
