This paper demonstrates a statistical analysis approach, which uses T-test and F-test for identifying whether the crack has significant impact on the total amount of power generated by the photovoltaic (PV) modules. Electroluminescence (EL) measurements were performed for scanning possible faults in the examined PV modules.
While on the one hand it is difficult to assess in detail their impact on the overall efficiency and longevity of a solar panel, they are one of the main sources of malfunctioning or even inactive cells. However, micro cracks are nearly impossible to avoid and – in the long-run –will affect most solar panels, including ‘high quality’ ones.

1. Introduction Cell cracks appear in the photovoltaic (PV) panels during their transportation from the factory to the place of installation. Also, some climate proceedings such as snow loads, strong winds and hailstorms might create some major cracks on the PV modules surface , , .
The module could produce less energy if these cracks restrict the flow of current through the cell. A local hotspot may eventually form in the damaged area of the cell, which can accelerate backsheet degradation and delamination, eventually increasing the risk that ground and arc faults will occur.
When cracks appear in a solar cell, the parts separated from the cell might not be totally disconnected, but the series resistance across the crack varies as a function of the distance between the cell parts and the number of cycles for which module is deformed .
As climate change accelerates and weather patterns change, force majeure events such as wildfires, hail and other storms are more likely to afect solar power plants. This white paper explains the problem of cell cracks and discusses how PV module buyers, investors and asset owners can mitigate risk by investing in durable PV modules.
