PV Modules Mechanical Load Tester

Application:

 Mechanical load tester determines the compression resistance of photovoltaic modules under static and dynamic loads such as wind, snow, or ice at different installation angles.

 The instrument adopts dynamic pressure holding technology, which simulates the PV modules under alternating pressure load test in positive and negative directions. It can accelerate the material fatigue and evaluate the reliability of PV modules.

 Labtech can customize the instrument as per the dimensions of PV modules with a certain amount of  cylinders and suckers.

Specifications:
