As reported by Chaibi et al. (2018), when the PV panel is exposed to dark condition (I L = 0), the overall resistance of the PV module is extracted using the ohm relation between the measured output current and voltage of the PV panel. This resistance represents the sum of the shunt and the series resistances.

Causes and Solutions of the Potential Induced Degradation (PID) Effect ...
PID reduces the performance of the PV modules due to a reduction in the shunt resistance of the electrical model (Figure 4). This corresponds to an increase in the leakage current, resulting in a decrease of the output current (and so, total output capacity) and affects the I-V curve as shown in Figure 5. Figure 4. One-diode model of a PV module.
Hail Damage Mitigation for Solar Photovoltaic Systems
Most damaging hail is heavy and falls more perpendicularly to the ground. Direct impacts perpendicular to a panel surface are the most damaging. Higher tilt angles decrease the chance of this.
