Mechanical Load Tester Solar Testing Equipment

Mechanical Load Tester is our most advanced test stand to simulate static and dynamic loads on modules and collectors. Twenty-four pneumatic cylinders with vacuum suction cups exert both compressive and tensile loads on the test sample, while reducing local mechanical stress points. The Mechanical Load Tester is a reliability test stand for quality and product development testing. It offers a high degree of operational ease and flexibility. A high total exertable force allows product development with testing to failure.


  • Reduced local mechanical stress on test unit through a high number of 24 suction cups
  • Fast and precise configuration of the cylinder array with mechanical coupling of the cylinders
  • Practical and ergonomic test setup through crank handles and scissor mechanisms
  • Fast adjustment for testing units of different sizes with sliding cross bars and quick release levers
  • High precision load measurement using sophisticated design of the force measuring frame
  • Static and dynamic load testing according to common international standards
  • Testing to failure through applicable forces up to +27 kN / -22 kN
  • Highly accurate deflection-measurement of the unit under test by optical distance sensors.
  • Electrical continuity measurement for PV modules available
