Dimensionamento de um sistema fotovoltaico e viabilidade econômica para atender a demanda do laboratório de energia e meio ambiente da UFRA/Capanema

Abstract

The energy resource generated by the sun, inexhaustible on earth scale, as much a heat source as light, it became, actually an alternative energy more promising in the energy supply to supreme human development. That way, the main objective of this work is promoting sustainability through the dimensioning of a photovoltaic system connected to the distribution network and economic viability to attend energy required for the Energy and Environment Laboratory belonging to the Federal Rural University of Amazonia. For this purpose, na analysis of the study site, data collection in the laboratory and in the database of the CRESESB to contribute to obtaining the irradiation of the municipality, the inclination and orientation of the panels, and to assist in the calculations for the choice of module and inverter.Subsequently, the economic feasibility of the project installation was realized as well as the financial return. In addition, a carbon credit estimate was also made, taking into consideration that consumers would no longer emit greenhouse gases into the atmosphere by using an alternative energy source. Initially it was calculated that the inclination angle of the modules was 10º. The peak power required to supply the demand was 14.74 kWp, from this, 44 photovoltaic modules of 330 Wp of powe r will be required. The viability of the project was analyzed through payback which resulted in less than 3 years it was possible to repay the amount invested and the annual profitability was over 32% in the first year. While reducing CO2, the study proposes a reduction of approximately 1866 kg per year. Finally the work is considered sustainable when it has economic viability and reduces environmental and social impacts through the use of clean energy.
