Análise de viabilidade técnica da implantação de um sistema solar fotovoltaico na Secretaria de Meio Ambiente e Controle Urbano de Maracanaú

Abstract

The increase in energy consumption over the years enforces a rethinking of the national energy matrix, for this reason, the search for new sources of energy less harmful to the environment becomes increasingly necessary. On the national scene, the solar irradiation levels provide a high potential for energy generation, which contributes to widespread solar energy as an alternative source. This work aimed to present a technical study analyzing the feasibility of implementing an on-grid photovoltaic system connected to the low voltage grid of the Secretaria de Meio Ambiente e Controle Urbano, located in the city of Maracanaú/CE. In order to achieve the goal, an overview study of the basic concepts and other works regarding the subject was made. As a result, it was recommended to install 124 photovoltaic modules with a 330 Wp value each, totaling 40.92 kWp. The obtained results show a 100% reduction in the estimated consumption of electricity from the utility. The calculated investment cost of the system is R$ 158,769.60 with a payback time of 4 years and 9 months.Therefore, it concludes that the photovoltaic system installation is able to supply the demand energy and be economically viable. For future projections, it is expected to increase the system so that the consumption of the entire administrative center is included in the project.
