ESTUDO DE VIABILIDADE DE IMPLEMENTAÇÃO DE ENERGIA SOLAR TÉRMICA E FOTOVOLTAICA NO RESTAURANTE UNIVERSITÁRIO EM RIO VERDE-GO

Abstract

Among all renewable energies, solar energy is a source considered as a promising substitute for traditional energy sources, which in turn are increasingly depleted. Although Brazil is privileged due to its high irradiance, its continental proportions and geographic location, resulting in an enormous potential for solar energy to be explored, solar energy has been discreetly participating in the energy matrix. The present study sought to design two systems, a photovoltaic and a solar thermal for the industrial kitchen of the university restaurant of the IF Goiano Campus Rio Verde. In the city, an average global horizontal irradiance of 5.19 kWh/m2 per day was observed. With the simulation of the solar thermal heating system, it was observed that to meet a demand of 2000 liters of hot water per day for the production of 250 meals, a system of solar collectors that results in 30 m2 is necessary. A comparison of the heat production of the solar thermal heating system with an estimate of electric energy production, obtained through simulation in SAM, system advisor model, a production of approximately 18000 kWh. In the case of the photovoltaic system, this study showed that to meet a demand for 250 meals, 285 kWh/day are required. The simulation at SAM was done so that the restaurant meets production for 5 days a week. It was observed that in all months of the year, a photovoltaic system with 144 polycrystalline silicon solar panels of 2 m2 each, meets most of the electricity demanded.
