2.2.1. Sample Preparation

In order to compare the different lightning protection performance of various PV modules and verify the accuracy of the simulation, three experimental samples were selected according to the models in the numerical simulation in Section 2.1. As shown in Figure 6a, a 213 cm × 105 cm framed double-glass PV module was selected as a counterpart piece and defined as Sample A, which was assembled by the metal frame and solar cells. At the same time, a 222 cm × 150 cm BIPV module unit combination was defined as Sample B, as shown in Figure 6b. In the lightning current withstand capability test in Section 3.2, the BIPV module unit with metal frame of 150 cm × 72.5 cm was selected for the test, which is defined as Sample C, as shown in Figure 6c.
