abstract: 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.
