TL;DR: In this paper, the authors present a statistical analysis on the crack formation in 27 crystalline silicon PV modules caused by a standard mechanical load test according to IEC 61215 10.16.

TL;DR: In this paper, the authors evaluate electroluminescence images of photovoltaic (PV) modules with respect to cracks and perform a simulation of the strain distribution on a glass plate subjected to a uniform mechanical load and supported at the edges.

TL;DR: In this paper, an upper bound for the potential power loss of PV modules due to micro cracks in the solar cells was derived by simulating the impact of inactive solar cell fragments on the power of a common PV module type and PV array and showed that the largest inactive cell area of a double string protected by a bypass diode is most relevant for the power loss.

TL;DR: In this paper, the potential of ultraviolet fluorescence imaging for the detection of function and safety failures of photovoltaic modules in the field is presented, and the authors apply this method to detect hotspots, mismatched cells, power-loss-inducing cracks, and show how they use it to evaluate the crack history of a module.
