Análise da viabilidade técnica e econômica de um sistema fotovoltaico em uma escola municipal de Campo Mourão – PR

Abstract

Brazil possesses vast potential for photovoltaic energy generation. In Brazil, a substantial portion of the electricity supply is derived from hydroelectric plants, which, despite utilizing a renewable resource, result in considerable environmental and social impacts. These include the destruction of native vegetation, river diversion, and disruptions to local communities. Given this context, solar energy emerges as an excellent alternative, as it reduces greenhouse gas emissions, decreases reliance on the petroleum market, and harnesses an inexhaustible resource4the sun. This study presents an analysis of the technical and economic feasibility of implementing a photovoltaic system in a municipal school in the city of Campo Mourão. The assessment is based on the most advantageous budget proposal obtained, complemented by economic engineering analysis tools. The results obtained showed an IRR of 27%, which is higher than the adopted Minimum Attractiveness Rate (MAR) of 12.25%. The NPV was R$ 37,648.60 for a 10-year period, with an ROI of 17.42% and a payback period of 3 years. Considering these figures, it is concluded that the economic feasibility of the photovoltaic system in the school under study is satisfactory.
