Comparação energética e econômica de três unidades fotovoltaicas operando em diferentes locais do estado de Mato Grosso do Sul

Abstract

Brazil needs to increase its electricity supply, however, this strategic action must be integrated to develop society in the economic, social, and environmental spheres, which affects even renewable energies, including naturally abundant solar energy. As the cost of installing photovoltaic systems has been falling every year and the environmental and social costs of conventional power plants are increasing, photovoltaic systems have become economically competitive. This study aims to compare energetically and economically three photovoltaic units in different cities in the state of Mato Grosso do Sul. To achieve the proposed objective, a review of the specialized literature was carried out, as well as a quantitative technical-economic analysis, using data that were obtained by monitoring a data logger connected to the photovoltaic inverter. It was concluded that the use of climatic conditions is crucial to increase the potential of photovoltaic energy produced internally. When analyzing the three plants chosen, the one in Nova Alvorada presented better results in the amount of energy produced, and the Rio Brilhante Unit had the lowest payback compared to the others.
