Abstract: Crystalline silicon photovoltaic (PV) modules are prone to the formation of cracks in the solar cells when subjected to mechanical loads. In extreme cases these cracks lead to an electrical separation of cell parts, thus reducing the power output of the module. We present the analysis of crack distributions in PV modules after being subjected to a uniform mechanical load.
