研究目的
To discuss the future of photovoltaics (PV) module reliability and the necessary updates to testing standards to accommodate new technologies and ensure long-term performance.
研究成果
The chapter concludes that while PV modules are extremely reliable, ongoing work is needed to update qualification tests, understand degradation mechanisms, and develop methodologies for determining module service life. It emphasizes the importance of these efforts as PV continues to expand its role in global electricity supply.
研究不足
The chapter acknowledges that the final published standards may differ from the draft summaries provided. It also notes the ongoing challenges in understanding degradation rates and extending module lifetimes.
1：Experimental Design and Method Selection:
The chapter discusses updates to IEC 61215 and IEC 61730 standards for PV module qualification and safety, including new tests for PID, cyclic mechanical load, and requirements for bifacial and flexible modules.
2：Sample Selection and Data Sources:
The updates are based on field performance data and the need to accommodate new PV technologies.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
Detailed procedures for new tests like PID and cyclic mechanical load are provided, referencing IEC TS 62804‐1 and IEC TS
5：Data Analysis Methods:
627 Pass/fail criteria for new tests are specified, such as a maximum allowable power loss of 5% for PID testing.
