摘　　要：晶体硅光伏组件在户外长期运行时,各种材料会出现性能衰退。通过探究一批使用约30年的多晶硅组件,发现其在户外使用28年后衰减率仅为5.37%。此外,通过长期监测组件发电性能研究其在广州地区的发电和衰减情况,并采用EL测试研究材料衰变对组件影响,评估光伏组件的可靠性。When operating outdoors over a lengthy period of time, performance degradation of materials of silicon PV modules would occur. The authors of this paper studied a batch of approximately 30-year-old polycrystalline silicon modules and found that the power degradation is only about 5.37%after 28 years outdoor operation. In addition, these modules were being monitored to study their electricity yield and power degradation in Guangzhou city, and the EL tes-ter was used to detect these modules＇ defects in order to find out the influence of material degradation towards module performance and evaluate the reliability of PV modules.
