Análise da viabilidade técnico financeira da implantação de um sistema de geração de energia elétrica através de módulos solares

Abstract

This paper discusses a case study on the implementation of a distributed photovoltaic system in a residential building located in the city of Curitiba, Paraná. Initially, the Brazilian energy matrix was analyzed, as well as the different forms of energy generation, the definition of the photovoltaic system, understanding its operation, the essential components of the system, as well as the calculations associated with the generation of solar energy, taking into account the location and type of installation. Subsequently, the steps for installing the system were examined, culminating in the selection of equipment to ensure the generation of the necessary amount of electrical energy demanded by the residence. After properly calculating the sizing of the system, the cost of installing the system and the feasibility of implementing the system were verified along with the calculation of the return on investment time (payback), NPV and IRR. In the last chapter, a comparison was made with before and after Law 14,300. At the end of the study, it was concluded that the photovoltaic system presents significant economic advantages for the residence, while at the same time contributing to the generation of energy in a sustainable and renewable manner.
