研究目的
Investigating the feasibility of predicting the service life of PV modules through accelerated stress tests and understanding the impact of design, manufacturing, and environmental conditions on module degradation and failure rates.
研究成果
The paper concludes that while it is challenging to predict the service life of PV modules with a single set of accelerated stress tests due to the variability in module designs and deployment conditions, it is possible for manufacturers to predict service life for their specific module types. This requires knowledge of the manufacturing process, feedback from field deployment, and extensive accelerated stress testing. The results can provide a baseline for evaluating future products of similar design.
研究不足
The study acknowledges the complexity of predicting service life due to the variability in module designs, manufacturing processes, and deployment conditions. The uncertainty in acceleration factors and the potential for measuring the wrong failure/degradation mode under highly accelerated stress tests are noted as significant limitations.
