Reliability of Battery Systems in Solar Power Plants, Interview with Erik Marstein, Task 13 Expert

PV+BESS Reliability: Performance, Ageing and Lifetime | IEA PVPS Expert Interview As battery energy storage systems (BESS) become increasingly integrated into solar power plants, understanding their reliability, performance and lifetime is essential. In this interview, Erik Stensrud Marstein (IFE, Norway), IEA PVPS Task 13 expert and lead author of the report Assessing the Reliability of Battery Systems in Solar Power Plants in Operation, discusses the key factors influencing the long-term performance of PV systems combined with battery storage. Drawing on the findings of the report, he addresses five key questions: Why is PV+BESS reliability an important issue? What determines PV+BESS performance and lifetime? How do different use cases affect battery ageing? What can we learn from real-world PV+BESS systems? What are the biggest knowledge gaps, and what needs to improve? The interview explores how battery technology, operating conditions and applications influence system reliability, and why better monitoring, operational data and degradation models are needed to support the growing deployment of solar-plus-storage systems. 📄 Read the full IEA PVPS Task 13 report for free: https://iea-pvps.org/key-topics/asses...
