Quality Check of Solar Modules

Testing solar modules and components is an important step in ensuring quality and yield, as well as the basis for repair or for the damage appraisal. Along with quality and performance tests with the most modern testing technologies, maintenance of solar modules and components is one of our additional services. Of course, all results are appropriately documented and can be traced for every single module and component.

Now there are three approaches to test or repair modules and components:

Testing and repair at the service Center

In our own service centre in Bremen we conduct quality and performance testing on solar modules and components with the most modern inspection technologies and also carry out repairs if necessary. These include, for example:

  • Visual inspection using our error criteria catalog
  • Performance measurement under STC conditions (Flashing)
  • Electroluminescence Imaging to identify micro cracks (EL test)
  • Infrared Imaging to detect hotspots (IR test)
  • Resistance measurement to identify insulation faults (WHP test)

Testing and repair on site

Thanks to the high-quality equipment in our mobile PV Test Centre, we can offer our clients even better, faster and more effective testing right at the plant’s site. Along with quality control at the plant or construction site, our mobile PV Test Centres are often in use for incoming goods inspections at ports such as Southampton, Rotterdam, Antwerp or Hamburg. Delays can be avoided and deadlines met for planned commissioning.

  • Visual inspection using our error criteria catalog
  • Performance measurement under STC conditions (Flashing)
  • Electroluminescence Imaging
  • Infrared Imaging

Testing and repair in installed condition

Depending on the problem, certain tests are needed in installed condition in order to determine the extent of external damage or product defect. Here it is not always necessary to dismantle components. Some tests can be conducted right on the roof.

  • Visual inspection using our error criteria catalog
  • Electroluminescence Imaging
  • Thermal imaging, if PID is suspected at a plant

Our test and service center

At our service center in Bremen qualified employees conduct quality and performance testing on solar modules and components with the most modern inspection technologies and also carry out repairs if necessary. Furthermore with the Mobile PV Test Center, we can offer our clients even better, faster and more effective testing right at the plant's site.
