DIMENSIONAMENTO E ANÁLISE FINANCEIRA DE UMA USINA FOTOVOLTAICA RESIDENCIAL EM VARGINHA / MG

Abstract

This work addresses the sizing and financial analysis of a residential photovoltaic power plant. Proper sizing is crucial to avoid unnecessary costs associated with oversized equipment. The analysis of energy supply and generation data, combined with evaluations of financial indicators, identifies the option with the lowest cost-benefit ratio between generating and purchasing electrical energy. The methodology employed a qualitative analysis approach combined with elements of quantitative analysis in a case study. The project took place in a residence in Varginha, Belo Horizonte III Residential Neighborhood, where an ON GRID system was installed. The analysis concluded that the photovoltaic power plant offers economic and sustainable advantages, generating clean and environmentally friendly energy. The sizing and deployment cost of a photovoltaic power plant were calculated, revealing an investment payback time of about 5 years for this project. The global trend toward clean energy sources and the growing demand for these solutions indicate a promising future for the photovoltaic industry. Analyzing investment in residential power plants is valuable, as despite initial costs, they have the potential to provide a short-term return on investment.
