Integrated Approach to Ancillary Photovoltaic Component Reliability Assessment

closed

This project is developing an integrated approach to assessing the reliability of power electronic components in photovoltaic (PV) systems. The new approach is based on the development of physics-informed degradation models embedded in digital twins, or digital replicas of power electronic components, then validated with accelerated life testing and field data. The team will record the causes of abnormal behavior in the power electronic devices and the amount of time taken to reach failure, then calibrate and validate against accelerated life testing and field performance and reliability data collected on actual electronic components found in PV systems.
