Resumen:
The current Brazilian energy crisis resulting from the scarcity of water resources, given that the national electricity matrix is concentrated in hydroelectric plants, and the growing demand for electricity consumption in socio-economic activities, has led to the need to use other complementary sources of generation. In this situation, thermoelectric plants have been the main option to meet this need, however, they generate large pollutants emissions, in addition to having a high production cost. Considering the great environmental impacts that thermoelectric generators cause, other technologies are more suitable due to being renewable and less polluting sources, such as wind energy and solar energy. Among the options, photovoltaic solar energy has been an excellent alternative because it is one of the most versatile and cheaper and because sunlight is abundant in practically the entire national territory. With this perspective, the present work sought to carry out a case study evaluating the project of the installation of a solar energy project in a residential condominium located in the city of Lagoa Seca in Paraíba. By carrying out the study, it was possible to highlight the evaluation of the financial methods of Net Present Value (NPV), Internal Rate of Return (IRR), and Discounted Payback attributed to the project. The economic feasibility analysis attributed to the installation of the photovoltaic solar plant in this work allowed us to conclude that utilization of this type of system is economically viable, strengthening its choice in expanding the use of new sources of electricity.
