Reliability of the photovoltaic systems

Abstract

This paper deals with the reliability of the PV system's connection to the distribution network. The first part defines the conditions for the PV system's connection to the distribution network, while the second part defines the factors influencing the reliability of the PV system's operation and connection to the distribution network. The paper contains production data describing the failure and subsequent analysis of the failure of central inverters of the PV system. In the conclusion there are recommendations for the use of methods to analyse faults and to determine system reliability.
