Estudo da viabilidade técnico-econômica de uma microgeração solar residencial

Abstract

With the presently energy global scene, it is necessary to search about new alternatives of power generation. Brazil receives high incidence of radiaton and that’s why this article presents a technical economic viability study of a residential solar microgeneration to the currently methodology (Grid-Tie and Off-Grid). It shows from technical analysis that the photovoltaic energy is payable despite the high initial investment. The contents of solar photovoltaic energy, together with the tariff and economic structure of Brazil, will be presented in a detailed way. Afterwards the place of implementation of the proposed study will be described, with the necessary information to develop the design for the two methodologies. With the sizing information, a survey of the current price of the components required for the study will be carried out. Finally, by combining the cost information with the energy profile of the residence, three techniques, Payback, VPL (Net Present Value) and TIR (Internal Profitability Rate) will be used to detect whether the project is viable or not.
