Mechanical Load Tester

Solar modules are becoming increasingly larger and lighter, which leads to a growing risk of mechanical damage in the field. As a result, mechanical load testing has become significantly more important in recent years.

The testing requirements are highly diverse, ranging from simple homogeneous loading of individual modules to complex non-homogeneous load tests that include the complete mounting structure. Typical applications include testing modules together with the torque tube in solar tracking systems.

PSE offers the right test system for every requirement. The portfolio ranges from the standard MLT18 test bench, specifically designed to meet international standard testing requirements, to fully customized solutions tailored to demanding customer-specific applications.

The requirements related to testing collectors and modules range from standard testing for single modules to comprehensive testing of complete elevation systems. Testing institutes face the challenge of reproducibly testing many different modules and collectors with a wide range of measurements, with minimal changeover time and optimal load distribution. In order to test the modules as realistically as possible, a climate chamber can simulate the influence of mechanical load under hot and cold conditions.
