Mobile Lab

The MBJ Mobile Lab in the 3rd generation combines a TÜV certified A + A + A solar simulator from MBJ Solutions with a high-resolution electroluminescence test system according to IEC 60904-9. The mobile laboratory for solar modules enables standard-compliant and precise on-site testing at maximum throughput. In one shift up to 300 modules can be checked in detail.

The laboratory optionally includes up to 7 test methods. In addition to the power measurement and the electroluminescence, the basic scope includes connection testing and the test of the bypass diodes. Optional there are air conditoning, thermography, high voltage measurement, grounding test and other add ons available.

Designed for mobile use

The Mobile Lab was developed by a team of specialists and with the know-how of MBJ Solutions, a leading provider of test equipment for module production, especially for on-site testing and now again improved in the fourth generation.

It includes all the measuring and testing methods required for an objective judgement of the solar modules on site. Under-performance but also hidden defects such as micro-cracks or inactive areas as well as hotspots in the module can be detected quickly and reliably.
