description: The problem of simulated low-velocity  hail impacts on flexible photovoltaic (PV) modules  resting on a substrate with variable stiffness is investigated.  For this type of PV module it is shown that the  prescriptions of the IEC 61215 International Standard  for quality control used for rigid (glass-covered) PV  modules should be augmented by taking into account  their real mounting condition and the stiffness of the  substrate in the simulated hail impact tests. Moreover,  electroluminescence inspection of the crack pattern  should be made in addition to electric power output  measurements.An implicit finite element simulation of  the contact problem in dynamics is also proposed, with  two different degrees of accuracy, to interpret the  experimentally observed extension of cracking.  Results pinpoint the important role of stress wave  propagation and reflection in the case of soft substrates.
