Análise técnico-econômica da instalação de sistema de geração fotovoltaica em uma unidade consumidora na cidade de Guariba – SP

Abstract

Due to the increase in use of renewable energy sources and its benefits, this case study had the purpose to design a photovoltaic system for a consumer unit at the city of Guariba­SP, presentng the economic Payback subtracted (PBd), Internal Return Tax (TIR) and the Actual Liquid Value (VPL) based on budget for its installation. The chosen place for this research was the Municipal School Professor Luiz Garavello, the design of the system foresawto supply the whole consumption of that unit dismissing the basic tariff. The software of choice was PV*SOL as well as the On­Grid system with energy compensation regulated by the normative resolution 482 published by the National Agency of Electric Energy at the year of 2.012. The project consisted on the identification of the best location for the installment of the 84 solar panels which were placed on the roof of the building and turned to the geographic North with a slope of 23.2° with a maximum shading of 0,4%. The panels were connected to a frequency inverted with a power output of 36kW in an arrangement of onestringbox with 14 panels in series and 2 panels in parallel. It can be concluded from the research has there is an economical viability on theinstallment of the photovoltaic system on the school, providing an annual saving of R$ 23.006,90. The project presented an internal return rate of 13,03%, a payback of 11 years offline and a VPL of R$ 176,956.72 showing that it is indeed financially feasible.
