Projeto de dimensionamento e acompanhamento da geração de uma usina fotovoltaica de 106 kWp em Laguna Carapã - MS

Abstract

The increase in values moved by energy sources has made the population look for new alternatives for energy generation. In view of this, this study had the general objective of discussing the sizing project, construction and monitoring of the electricity of a 106 kWp photovoltaic plant in Laguna Carapã - MS. The specific objectives consisted of dimensioning and evaluating the performance of the plant, as well as the economic analysis. A descriptive study was carried out, both qualitative and quantitative, considering the issue of project dimensioning and energy generation. The theoretical basis has a bibliographical study, with the research descriptors: national energy matrix, photovoltaic plant; sizing; power generation, photovoltaic systems. It dealt with the design of photovoltaic systems connected to the distribution network, components, recommendations, main national standards, as well as information on performance. A generation follow-up was performed for purposes of comparison with generation values estimated through theoretical calculations. The results showed that photovoltaic systems are subject to several factors that directly affect the efficiency of the system. With a generation higher than expected of 22.43% in the first monitored quarter and a lower than expected generation of 10.29% in the second monitored quarter. the work also analyzed the financial viability, showing a return on investment after 3 years and an internal rate of return of 26.23%. The work concluded that the evaluated photovoltaic power generation system presented economic viability because the internal rate of return (IRR) of 26.23% of the photovoltaic system was higher than the estimated minimum rate of attractiveness (TMA) of 9.25%, the demonstrating the economic viability of the project.
