Análise de viabilidade técnica e econômica da instalação de um sistema de energia fotovoltaico.

Abstract

In 2001 occurred in Brazil an electric energy crisis, restricting temporarily the use of electricity in several sectors of the economy. From this, how alternative solution to the energy deficit, arose the incentive for cogeneration of electric energy. The transformation process of solar energy in electrical energy through photovoltaic panels is a cogeneration example. In this context, we carried out a study of the economic viability of implantation of photovoltaic panels in a residence as an option for reduction of electric energy conventional consumption, which represents average monthly consumption of 395 kWh. The energy transformation system projected consists of 10 photovoltaic panels, one Inversor and one string box. The total savings generated by the system was R$ 68.272,00 in 20 years and the payback period investment of R$ 23.254,49 occurs in between the seventh and the eighth year. Being 25 years the use time of photovoltaic panels, the use of technology, in actuality, presents economic viability.
