1. **标准测试局限**:现有模块标准仅能检测早期失效,无法预测或保证25+年寿命,问题具有技术特异性。 2. **新型电池失效模式**:HJT和TOPCon电池存在PERC中未见的失效模式(如HJT四种湿热失效、TOPCon三种失效),需通过电池级诊断(比模块测试快10-100倍)定位根源。 3. **封装剂关键影响**:封装剂添加剂(如UV吸收剂)与金属化层反应导致酸腐蚀,引发UVID(紫外线诱导降解),供应链敏感性差异达5倍。 4. **钙钛矿可靠性缺口**:钙钛矿模块存在未解决可靠性问题,UNSW发起匿名实地测试计划(2025年启动),涵盖商业与预商用模块。 5. **AI运维平台**:P2AgentX模型支持太阳能电站AI实时检测损耗,提升运维效率。
