Abstract: In large-scale PV plants, inverters have consistently been the leading cause of corrective maintenance and downtime. Improving inverter reliability is critical to increasing solar photovoltaic (PV) affordability and overall plant reliability.
In, the reliability of PV inverters under non-unity power factor operation and low-voltage ride-through is studied, but the reliability degradation rate and estimated lifetime of inverters are not specified.
4.6 Inverter System Reliability and Lifetime The system reliability of the inverter depends on the number of components. In a system with n components, the system cannot perform if one of the n components fails. The total unreliability is given by:
Conferences > 2023 IEEE 50th Photovoltaic S... In large-scale PV plants, inverters have consistently been the leading cause of corrective maintenance and downtime. Improving inverter reliability is critical to increasing solar photovoltaic (PV) affordability and overall plant reliability.
Up to a certain point in time, the entire lifetime of a PV inverter was predicted based on the failure rates of individual components and handbooks provided by the manufacturers. In recent years, the prediction of the reliability and lifetime of power converters has been done through physics-of-failure assessments.
