Sizing of a Photovoltaic Solar Park for the Center for Agricultural Mechanization (CEMA)

Abstract

This work deals with the foundation and proposal for the dimensioning of a photovoltaic solar park destined to satisfy the demand for electrical energy in the facilities of the Center for Agricultural Mechanization (CEMA) of the Agrarian University of Havana. For this, a study of the behavior of electricity consumption was carried out in CEMA, as it is considered a high consumer. It was determined that, to satisfy the energy demand, the photovoltaic solar park must have 323 solar panels of the BS18055 model, an accumulation system composed of 47 Trojan monoblock batteries, two Victron Energy model current regulators (input current of 2054.28 A and 1135.09 A output), as well as a 1000 kWh inverter. An analysis of the economic and environmental impact of the proposed installation was carried out, which showed that it will allow an electrical energy saving of not less than 29,421.72 kWh per year. Likewise, it was determined that, due to this unconsumed energy, at least 33.24 t of CO2 per year would cease to be emitted into the atmosphere. Then, at least 7.7 t of fossil fuel would stop being consumed in the same period, thus representing a total saving of at least 57,368.23 CUP, for energy not consumed annually. To undertake the proposed installation, the preliminary cost estimate of the investment was calculated, which is around 244,583,376 CUP, if the energy storage system is included, and 935,376 CUP, not including the energy storage system.
