Análise Técnica e Econômica de um Sistema Fotovoltaico de 250kwp Conectado à Rede e Instalado em uma Propriedade Rural no Oeste do Estado do Paraná

Abstract

Among the several clean generation systems, the photovoltaic energy generation system connected to the grid stands out, partially or totally meeting the required demand. Easy to install, it has become the main model sold in Brazil. This work aims to analyze the technical and economic feasibility of a photovoltaic system connected to the grid with a capacity of 0.25MWp, in a rural property in the municipality of Maripá in the West of Paraná. The system consists of 1200 photovoltaic modules of 270Wp, making a total of 324kWp installed. For connection to the network, 5 inverters of 50kWp were installed, totaling 250kWp of capacity. For the technical analysis, the design aspects of the photovoltaic generating plant were evaluated, economic feasibility analysis, using the discounted Payback method, used the system generation data and the electric invoice to determine the avoided cost, for the rural property and determined the Present Value (VP) and Discounted Payback indices for the invested capital. purchasing and installing the system on the property. As a result, 14 years were obtained for the return on invested capital.
