TÜV Rheinland said the new system’s ability to handle different module sizes combined with a wide range of software features was a “big advantage” for its work.
The company said it would use the system for its own R&D activities as well as the supervision of serial examination on PV modules in the future.
“We are happy to have TÜV Rheinland as a new customer. This is a very important reference for MBJ Solutions,” said Dr. Michael Fuß, Chief Executive of MBJ Solutions.
Electroluminescence technology allows the detection of module defects invisible to the human eye, such as micro cracks, electrically inactive areas or grid failures.
