Estudo de implantação de um sistema fotovoltaico em edifício com três pavimentos, na cidade de Campo Mourão-PR

Abstract

Due to its intertropicais majority location and high solar radiation index, Brazil has significant potential for renewable energy generation, with photovoltaic electricity standing out. The market is increasingly stimulated due to new Normative Resolutions and incentive laws. Investing in a grid-connected photovoltaic system emerges as a highly viable option, also highlighting its sustainability aspect, as it is an efficient, clean, and inexhaustible alternative for energy generation, leading to a reduction in greenhouse gas emissions. Distributed generation in buildings with multiple consumer units is a solution adopted by many commercial buildings and condominiums. Thus, this study conducted an investigation on the implementation of a photovoltaic system in a three-story building in the city of Campo Mourão, Paraná, Brazil. The technical and economic feasibility of the best budget proposal was analyzed using economic engineering formulas (VPL, TIR, detailed payback, and ROI). The results indicated an TIR of 19%, which is above the adopted Minimum Attractive Rate (TMA), a VPL of R$ 28,188.89 at the end of the 10-year period, an ROI of 18.84%, and an investment payback of approximately 3.6 years, thus demonstrating the satisfaction with the economic viability of installing the photovoltaic system in the building under study.
