IEA PVPS - Photovoltaic Power Systems Programme 231d ago

In this IEA PVPS expert interview, Marc Koentges, Task 13 Expert, shares key insights from the latest work on PV system reliability. He discusses the main findings of the new Degradation of PV Technologies Report and the updated PV Failure Statistics (PVFS), explaining what the data reveal about real-world performance and reliability trends across different PV technologies. Marc also highlights why these outcomes matter — how improved understanding of degradation and failure patterns supports better system design, more accurate performance expectations, and stronger long-term confidence in PV. He offers reflections on the global impacts and benefits of Task 13 activities, including how reliability insights help support the industry, researchers, and stakeholders worldwide. Finally, Marc outlines the next steps for Task 13, including future work on reliability topics related to emerging technologies, components, and system configurations, as part of the new ST2.2 activity. This conversation is part of our ongoing series with IEA PVPS experts, bringing you insights from leading researchers and practitioners shaping the future of sustainable PV. 📘 Download the full report "Degradation and Failure Modes in New Photovoltaic Cell and Module Technologies": https://iea-pvps.org/key-topics/degradation-failure-modes-new-cell-module-technologies/ 📘 Download the Photovoltaic Failure Fact Sheets 2025: https://iea-pvps.org/key-topics/photovoltaic-failure-fact-sheets-2025/ 👉 Don’t forget to like, subscribe, and turn on notifications to stay updated on the latest in PV sustainability, circularity, and innovation.
