摘要
机械载荷试验作为考查光伏组件可靠性的重要手段之一,新版IEC标准中对于该项测试的要求也变得更加细致。本文介绍了一种光伏组件机械载荷测试的可调节式安装夹具设计,并根据标准IEC 61215-2:2016中静态机械载荷试验的要求,利用该夹具测试了两块不同版型的光伏组件。本设计夹具表现出良好的普适性与测试可靠性,测试结果表明破损程度直接导致光伏组件发电性能的降低,而其内在原因可能在于内部电阻的变化。
Mechanical load(ML)testing is a kind of methods which demonstrate the reliability of photovoltaic(PV)modules.The more meticulous procedures are inclined in new version IEC standard.In this paper,we introduce a design of an adjustable fixture for ML testing,and two different sized PV modules were conducted ML testing according to standard IEC 61215-2:2016.The designed fixture exhibited good applicability and testing reliability,and the test results showed that the crack degree directly induced the degradation of PV modules power generation performance.As the probable reason is the inner resistance change after the ML testing.
