Universal testing machine inspekt solo 2.5 kN for solar module testing

Determination of the mechanical properties of solar panels

Universal testing machine inspekt solo 2.5 kN

This universal testing machine inspekt solo 2.5 kN allows together with a special testing device to test in production the mechanical properties of solar modules, e.g. thin film solar modules.These modules consist of laminated glass, without any frame. So-called backrails are on the backside of the modules for the mechanical fixing as well as junction boxes with cable and plug for the current output.  With the machine and the special testing device, it is possible to perform tests in accordance to DIN EN ISO 527-3 Determination of tensile properties (Part 3: Test conditions for films and sheets) durchgeführt werden. The determination of the mechanical properties consists of two single tests: the pull-off of the junction box and the adhesive test on the backrail. In the first test, the adhesive bond between junction box and solar panel is tested regardin its durability. Possible mounting operations are simulated here. In a second test the adhesive bonds on the backrails are tested. Environmental influences like wind which have an impact on solar modules in use are simulated.
