Verificação de viabilidade econômica de um sistema solar fotovoltaico com base em análise nas faturas de energia elétrica

Abstract

It is currently impossible to imagine life without the presence of electricity. It is part of practically all activities carried out by man, being present both in everyday activities and in essential activities for the maintenance of world economic development. Its absence would imply a serious setback in the evolution of society, bringing social and economic losses. There is an increase in energy demand in the world, a search for new, profitable and sustainable energy sources. Based on this, photovoltaic solar energy, that it is produced from sunlight, is today considered an alternative, clean, renewable and sustainable energy source. Based on these regulations, an increase in demand in the production of photovoltaic solar energy was triggered in Brazil, given that the country has one of the most expensive energy tariffs in the world, with high tax burdens. However, the investment to install a photovoltaic solar energy generation system is still quite high in Brazil, which generates some uncertainties regarding the return on invested capital. was to carry out an analysis to verify the economic viability of a photovoltaic system in the distributed generation modality, based on data collected in a system in effective operation for one year. This verification analyzed the production of solar energy produced in 12 months of operation, and based on these data, a study was carried out to verify the economic feasibility and return on invested capital, comparing with the feasibility study presented before the implementation of the system. As a result, the short, medium and long term risks and benefits related to the investment, installation and maintenance costs were analyzed, and through the calculations presented, an analysis of the return on investment.
