Estatística de falhas em sistemas solares fotovoltaicos

Abstract

Photovoltaic solar energy is one of the fastest growing renewable sources in Brazil and in the world, therefore, there is a great concern with the efficiency of generation and with the errors that can affect the functioning of the solar system. As a result of this concern, 4 statistical analyzes were carried out with the aim of understanding what are the most recurrent types of failures, where they are located and what their causes are. With that, the data used in the analyzes were extracted from the systems monitoring platform, which was provided by an installation company in the state of Alagoas, containing information on failures, for a period of 6 months, and on the voltage of the distribution network, of two periods, 15 and 30 days, during the functioning of the solar systems, the day. In view of the need to understand where the biggest problems that this energy faces were, the study was carried out and obtained a surprising result, since the number of failures in some systems were very large, where they were of different types, the main ones being, mains/island drop, undervoltage and overvoltage.
