Estudo de viabilidade de uma usina solar de 5 MW com tracker

Abstract

The present work proposes to make a study of technical and financial feasibility of a Photovoltaic System Connected to the Network (SFCR), of 5 MW with the use of solar tracker system to be installed in a locality in the municipality of Pacajus, Ceará. The photovoltaic (PV) plant will make use of a single-axis solar tracker, and the initial investment of the project takes into account the costs of equipment, commissioning and electromechanical assembly, to obtain the total cost of investment. A 6,250 kWp PV plant was dimensioned, counting a nominal power of 5,000 kW, where 14,205 440 Wp modules will be used, being associated in a string with 28 modules, thus the park has an expected annual PV generation of 11,388,000 kWh. The project's financial analyses were performed using the concepts of Minimum Rate of Attractiveness (MRAP), Net Present Value (NPV), Internal Rate of Return (IRR) and Levelized Cost of Energy (LCOE), and also the remuneration of its shareholders assuming the PV plant's profit through taxation by Presumed Profit. A 75 % financing of the project through the Green FNE line of the Banco do Nordeste was considered. For the model and simulated conditions, an AAR of 7.2% per year was stipulated, thus obtaining a positive NPV, an IRR greater than the AAR, and a Simple Payback of more than 10 years.
