Backsheet delamination refers to the separation or peeling of the layers in the material that forms the back of a photovoltaic (PV) solar panel.
Backsheet delamination can occur due to a variety of reasons, such as exposure to extreme temperatures, physical damage, or aging. In some cases, the delamination may be superficial and have no significant impact on the performance of the panel.
However, in other cases, the delamination can be more severe and allow moisture to penetrate the panel, leading to electrical faults or degradation of the panel's performance over time.
Backsheet delamination is considered a defect in the solar panel and impacts the reliability and longevity of the panel.
Regular inspection of the panel, including the backsheet, is important to ensure that it is functioning properly and to identify and address any issues that may arise.
