Peel-off tester for PV Module laminate

The connection between the laminate and all other components of a PV module are essential for a high durability and long lifetime of PV modules. Only when the laminate protects the electrical components from humidity and water is a good insulation guaranteed.

For the analysis of the compound between laminate, cell and glass, PSE AG offers a peel-off tester especially developed for the peel-off test on PV modules.

The peel tester can be placed on any PV module and is able to pull in a constant angle of 90° or other pull angles. The pull speed can be adjusted and the pull force is recorded during the entire test.
