Abstract/Summary:


The present work aims to gather, analyze and organize the information available in the literature about failure modes and failure rates in photovoltaic systems, mapping their origins and conditions under which they were obtained to provide unambiguous and trustworthy information for reliability studies on general PV systems. A set of guiding questions have been listed to clearly detail the original context of each publication. Filtering the references with failure information based on field data, the most common failures registered in PV systems were identified. With this information, a list has been created containing the failure rates for the major components in the PV system: transformer, inverter, and PV array. In particular, the failures in the PV module are detailed further according to its internal components and failure modes. This information can be used in reliability studies regarding the general behavior of a PV system.
