Analysis on Annual Attenuation Rate of PV Modules Due to Natural Aging
-
摘要: 针对光伏组件自然老化年度衰减问题,利用CTC国检集团(中国建材检验认证集团股份有限公司)在海南的户外老化基地,对32家主流光伏企业进行了户外老化测试,通过对两个自然年内组件衰减率和发电量测试得到的相关数据进行对比和分析,得出了我国主流光伏组件的衰减率规律以及晶体硅组件在不同辐照下的性能表现趋于一致的结论.Abstract: Based on the problem annual attenuation rate of PV modules due to natural aging, 32 mainstream PV companies outdoor aging tests were conducted in the outdoor aging base of the CTC Group in Hainan Province. Comparing and analyzing the related data obtained by testing the natural annual attenuation rate and power generation amount, it was obtained that the law of decay rate of mainstream photovoltaic modules in China and The performance of crystalline silicon PV modules under different irradiations tends to be consistent.
