Análise da geração de energia e dos índices de mérito de sistemas fotovoltaicos conectados à rede em câmpus do Instituto Federal de Educação, Ciência e Tecnologia de Goiás

Abstract

Solar energy is Solar energy is a technology renewable, sustainable and with high potential for capturing, converting and generating electricity. These characteristics favor investments in this technology, so that is necessary to understand the challenges that currently involve solar energy, such as performance limitations. Thus, in this work, are developed analyzes of electricity generation and merit indices of Photovoltaic Systems (SFV) installed in IFG Campus in order to evaluate the system with the best performance and the factors that provide this best performance. Firstly, is carried out Case Study I, in which is compared the performance of two strings, one with cooling and the other without cooling, belonging to a SFV in a pilot plant installed on the ground in the Aparecida de Goiânia Campus. In this study, is also verified the credibility of the calculation procedure adopted to obtain the merit indices Capacity Factor (FC), Final Yield (YF), Reference Yield (YR) and Performance Ratio (PR) by through comparing results with the academic literature. Subsequently, is carried out Case Study II in which the performance of three SFVs from the Goiânia Campus and one from the Itumbiara Campus is compared by through the application of the merit index calculations used in Case Study I. In this study, is also carried out the analysis of the generation of electric energy. The results of Case Study I indicate that the string with cooling has a subtly superior performance to the string without cooling and the results of Case Study II indicate that the best performance is verified in an SFV submitted to a specialized cleaning service in its photovoltaic panels.
