Viabilidade econômico-financeira de um sistema fotovoltaico para o setor residencial nos Estados Brasileiros.

Abstract

Micro and mini-generation can be an attractive option for the Brasilian residential sector because of the constant rise of the conventional electricity price compared with the micro and mini-generation. Having this motivation and considering the great availability of solar ressource Brasil, it was calculated an economic assessment of photovoltaic systems applied in distributed generation. This assessment was performed for the 27 Brasilian states as result it was calculated the levelized cost of electricity (LCOE) for the photovoltaic systems applied in the residential sector and calculated the payback (return time of the investment). These two measures are used to evaluate the economic potential of a photovoltaic system in Brasil. As a result, it was found competitive prices for the use of SISTEMA FOTOVOLTÁICO systems applied to distributed generation. The LCOE price for SISTEMA FOTOVOLTÁICO system is influenced by several parameters and in this work, it was considered a scenario in specific, such as considering the application to the residential sector and a small photovoltaic system with an installed capacity of 1.5 kWp.
