This standard defines a test sequence that will quickly uncover PV module failures that have been associated with field exposure to thermal cycling for many years. This standard was specifically developed to relate to thermal fatigue failure of tabbing ribbon solder bonds, however will also apply, to some extent, to all thermal fatigue related failure mechanisms for the assemblies submitted to test. IEC 61215, the PV module qualification test, already includes an accelerated thermal cycle sequence in one leg of the testing, however, the parameters of that test only represent a qualification level of exposure. This test procedure applies more stress and will provide a route for testing to differentiate PV modules with improved durability to thermal cycling and the associated mechanical stresses.
