Análise da viabilidade de geração de um sistema fotovoltaico: estudo de caso residencial.

Abstract

For many years mankind has focused its attention on energy sources from fossil fuels that have great environmental impact. As a way to reduce the emission of pollutant gases in the atmosphere and to make better use of the available energy sources in nature, photovoltaic energy emerged a few decades ago and today appears as a possibility for the generation of electricity. This work seeks to conduct a study on solar energy. In order to do so, the research was carried out respecting the basic knowledge that involves the subject, as well as to deepen the technical knowledge in projects of installation of photovoltaic modules. For the study was chosen a residence in the municipality of Teresina-PI and to make the project as reliable as possible were taken into consideration aspects such as: system losses, inflation, available area, panel slope and solar radiation at the residence. Finally, an economic analysis was carried out to determine if the project is viable or not. For this, we used economy techniques such as Payback and Net Present Value (NPV).
