Reliability Analysis of Micro-Inverters Considering PV Module Variations and Degradation Rates

This paper analyzes the impact of PV module variations on the micro-inverter reliability. The evaluation results show a significant deviation in the micro-inverter reliability for different PV modules. Moreover, the PV module degradation impacts are also taken into consideration in the reliability assessment. Such information can be used to reduce the cost of the final designed micro-inverter and better match the PV application.
