雷击可能导致故障并导致光伏（PV）模块退化。本文研究了多晶硅光伏组件（额定电压为6 V，1.5 W）在雷电感应电压作用下的电性能退化。光伏组件经受1.2/50 μ s正极性标准雷电冲击电压。这些测试的雷电冲击电压的峰值电压为1000 V。进行了两组实验。测试组1中的样品经受高达3000个脉冲的雷电冲击电压测试。给出了它们的I-V特性曲线。在测试组2中，对光伏组件进行热处理，直到其绝缘层中出现气泡。然后，在与试验组1相同的试验条件下，对该模块进行了雷电冲击电压试验。对试验组1和试验组2进行了比较。雷电冲击电压导致样品的强烈降解，并产生气泡，导致PV模块击穿。
Lightning strikes can lead to failure and cause degradation of Photovoltaic (PV) modules. The paper studies the electrical degradation of a polycrystalline silicon PV module (rated 6 V, 1.5 W) caused by lightning induced voltage. The PV module was subjected to 1.2/50 μs standard lightning impulse voltages with positive polarity. The peak voltage of these testing lightning impulse voltages are 1000 V. Two groups of experiments were performed. Samples in test group one were subjected to lightning impulse voltage tests up to 3000 impulses. Their Current-Voltage (I-V) characteristics were presented. In test group two, heat treatment was performed to a PV module until bubbles appeared in its insulation layer. Then, this module was taken into lightning impulse voltage test at the same test condition as in test group one. Comparisons are made between test group one and two. The lightning impulse voltage causes strong degradation of the sample with bubbles that leads to breakdown of the PV module.
