Estudo de viabilidade de um sistema de geração distribuída fotovoltaica na estação Juscelino Kubitschek em Fortaleza

Abstract

Many companies nowadays, in search of minimizing expenses and reduce energy costs, find photovoltaic solar generation a very attractive investment. Transport companies, such as METROFOR, which have several available areas distributed throughout a region, can take advantage of a distributed photovoltaic generation system installed in a station, at a discount on its own energy bill or other units registered by the same owner. Therefore, the present work studies the technical and financial feasibility of the generation of electric energy by photovoltaic modules at the Juscelino Kubitschek station on the Sul line, in Fortaleza, Ceará. Using the SketchUp software, the 3D modeling of the station is initially carried out, delimiting the free area on the roof and then the shading-free area available for the implementation of the system. After the graphic representation has been completed, a 93 kWp generation system is designed, consisting of 372 panels with 250W each and 15 inverters with 6500W of maximum power. With all the values, the financial analysis is made using the RETScreen software, and then the amount of R$ 318,060.00 of initial investment is determined, a simple rate of return, or payback, of 6.8 years and return on equity of 5.3 years, in addition to the reduction in emissions of 11.7 tCO2 per year. The efficiency of the methodology used is then proven, attesting to the project's viability.
