Cell cracks in solar photovoltaics can also occur while transporting or installing them; environmental factors such as snow, strong winds, and hailstorms can cause cracks in the solar panel as well [81, 82]. Different types of cracks can occur in PV modules, including diagonal, parallel to the busbar, and perpendicular to the busbar.
Authors to whom correspondence should be addressed. The degradation of solar photovoltaic (PV) modules is caused by a number of factors that have an impact on their effectiveness, performance, and lifetime. One of the reasons contributing to the decline in solar PV performance is the aging issue.
Corrosion poses a significant challenge for the performance of photovoltaic modules, which is primarily caused by moisture in its various forms: water vapour, dew, rain, snow, and ice. Approximately 19 % of observed degradation in PV modules is attributed to corrosion .
The solar PV’s output power decreases as a result of these airborne particles building up on its surface and causing shedding on the PV panel. However, the shape, size, and accumulation structure of dust may affect the shedding and its effect on both the lifetime and the efficiency of the PV module.
The possible impact of a crack and its position on output power degradation might significantly shorten the PV panel’s expected lifetime. The significance of a crack depends on the percentage of damage to a PV cell. This study found that 50% of damaged cells are cracked parallel to the busbar.
