Análise de viabilidade da instalação de um sistema fotovoltaico no estacionamento do DEE.

Abstract

The uninterrupted search for the ingress of new sources of renewable energy in BrazilianÕs energy matrix, associated with environmental concerns and the great potential of solar irradiation in Brazil, mainly in the northeast, makes the country an attractive location for investment in solar energy. This paper presents a design project of a photovoltaic system that will hold the cover function for the parking of the Department of Electrical Engineering at the Federal University of Campina Grande, in conjunction with its respective analysis of economic viability, based on the parameters of Net Present Value, Internal rate of return and payback. The project consists of a photovoltaic system connected on the public network with 648 panels of 265 Wp switched on 3 c.c./c.a inverters 55 kW each, the system is able to provide approximately half of the demand required by the load. The financial analysis was performed based on the fare table of ANEEL (National Electric Energy Agency) and compared to an investment in savings. The proposal presented is economically viable with a payback period of 10 years, thus a motivation for the Brazilian solar energy market.
