Análise da viabilidade econômica na instalação de um sistema fotovoltaico para geração de eletricidade

Abstract

The antagonism that exists between the continuous increase in energy demand and the constant shortage of supply creates the ideal scenario for the development and access to other sources of energy that have not been widespread before. In the search for new alternative sources, photovoltaic solar energy is an excellent option because it is abundant, renewable and clean, making it a great source of complementary energy, even for the primary sector, which suffers or reflects on production costs. This paper aims to disseminate the development of electricity generation through the direct conversion of sunlight into electricity through the photovoltaic effect and presenting its economic viability through investment project studies. For the purpose of assisting decision making, we employ methods that allow, from an initial investment, to find future returns with the savings generated. In order to enable better budget planning and predictability of expenditures, we apply the indicators of net present value, internal rate of return and return on investment, that together, demonstrate the reduction of production costs with the savings generated by the energy matrix proposal.
