Sistema fotovoltaico conectado à rede: estudo de caso em duas unidades consumidoras de mesma titularidade

Abstract

With the current Brazilian energetic crisis, along with the worry for the future of the planet due to the environmental problems faced, with emphasis on global warming, the use of renewable sources has become more than a way to fight the future degradation of the planet, has also become a viable way to save resources and play an important role in the preservation of the planet. This work presents an economic feasibility study of a grid-connected photovoltaic system for two consumer units with the same holder. The analysis is made of a case study, taking into account the monthly consumption of electricity of the last 12 months of the two units. The generated power credits will be distributed between the two units, according to the need of each one. The study will analyze the implementation costs, payback of the system and the amount of money saved along the system life cycle. It were used the methods of simple payback and present value, generating a total payback of 5,6 years.
