The reliability of photovoltaic (PV) modules is critical in harsh outdoor environments, where they are exposed to various stresses that can cause various degradations. In recent decades, the frequently observed degradation called snail trails in crystalline PV modules, is enormous concern due to less clarity about its effects on PV module .

We introduced a method to make snail trail evaluation samples effective and succeeded in adjusting test conditions to make it faster for the snail trails to appear on samples. An experimental comparison is also made to reflect the mechanism and factors of snail trails.

Snail trails typically appear after only a few years and can have multiple causes, often attributed to lower-quality panels. Defects in these panels can allow moisture to enter through the back sheet, causing oxidation between silver paste, a key material used in manufacturing, and the encapsulation material.

Other than light-induced degradation and potential-induced degradation, there has been another failure mechanism, which affects the reliability of the PV modules. Snail Trail (also known as snail tracks or worm marks) have been observed in outdoor conditions, which appears as brownish discoloured contact fingers especially around the cell edges .
