Numerical and Experimental Study of Lightning Stroke to BIPV Modules

Building Integrated Photovoltaic (BIPV) modules are a new type of photovoltaic (PV) that widely used in distributed PV stations on the roof buildings for power generation. Due to high installation location, BIPV suffer from lightning hazard greatly. In order evaluate risk stroke and consequent damage modules, studies attachment characteristics energy withstand capability conducted, respectively, based numerical experimental methods this paper. study characteristics, simulation results show it is easier charges concentrate upper edge metal frame. Therefore, electric field strength at enhanced emit upward leaders attract downward leaders. The conclusion verified through long-gap discharge experiment voltage lab. From multi-discharge lab, found interception efficiency module improved by 114% compared with traditional modules. capability, thermoelectric coupling model established. With model, potential, current temperature can be calculated multi-physical simulation. maximum frame increases 16.07 °C when 100 kA flows does not bring any have good consistency obtained impulse
