Hail tests on photovoltaic (PV) modules should be beyond the conventional testing. Power reduction of 21.47% is observed in glass to backsheet PV modules under hail. PV modules with front glass thickness of 4 mm can withstand severe hail damage. Use low wet-leakge current resistance modules for high hail-prone regions.

What happens if a PV module breaks?

Naturally the hail falls randomly at all the position of the PV modules, so the effect of any position or any location will depend on the hail impact because at different position the result of hail fire is different that's why the strike of hail is randomly. If the module is break it means the module is fail and the power loss. 2.

Are mono-crystalline PV modules better than poly-crystalline solar panels?

Notably, mono-crystalline PV modules exhibited better resistance to hail loads compared to their poly-crystalline counterparts.
