Component testing of substructures for photovoltaic modules

The requirements for testing components used in substructures for long-term care insurance modules have changed significantly due to new areas of application and the reduction in module costs. The combination of long-term care insurance modules and substructures is becoming increasingly important, particularly for flat roofs with different types of roofing and where little or no ballasting is required. Changes in materials, away from aluminum to sheet metal constructions, enable simplified installation using plug-in connections instead of screw connections.

At Fraunhofer IMWS, we offer comprehensive component testing for substructures of long-term care insurance modules. Our expertise and many years of experience in the section of material and component testing enable us to guarantee the highest quality standards and ensure the reliability of your products.

Our testing procedures include both destructive and non-destructive methods to examine the behavior of components under thermal, chemical, and mechanical stress. By using state-of-the-art technologies and equipment, we can deliver precise and comparable results that help you identify and eliminate potential defects at an early stage.

 

The advantages of our component testing

  • Ensuring product quality: Ensure that your products meet the highest quality standards and satisfy your customers' expectations.
  • Avoiding product defects: Detect defects early to avoid costly recalls or repairs.
  • Safety and reliability: Our tests help ensure that your products are safe and reliable, especially in safety-critical industries.
  • Cost efficiency: Early problem detection and correction can save costs in the long term.

Testing of photovoltaic substructures on the multi-axial test rig at Fraunhofer IMWS

The quality and durability of photovoltaic (PV) substructures are crucial for the overall performance of solar power systems. Comprehensive component testing is necessary to ensure the structural integrity and service life of these systems. At Fraunhofer IMWS, we use our multi-axial test field, among other things, to simulate realistic conditions using various test methods.

  • Static loading: One of the most basic test methods is static loading. This test is performed by applying constant loads to the substructure to evaluate its strength and stability. Static loading makes it possible to identify critical points in the structure that could potentially fail and serves as a basis for evaluating structural safety.
  • Fatigue loading: In addition to static loading, fatigue loading is also very important. This test simulates cyclic loads that can occur during the operation of the long-term care insurance system, such as wind and snow loads. By analyzing the fatigue resistance, the service life of the structure can be estimated and potential weak points can be identified.
  • Measuring systems: Modern measuring systems are used to precisely record deformations and stresses during the tests. Optical strain measurement with gray value correlation is a highly accurate method that allows changes in the surface structure to be analyzed during loading. This technique offers the advantage of being contactless and therefore does not affect the integrity of the sample. In addition, displacement measurement is used to monitor the structural shifts under load and obtain further data on deformation.
