Mobil Test Equipment - for the PV-Industry

Our mobile measurement and testing equipment for on-site testing of solar modules includes A+A+A+ LED sun simulators, high-resolution electroluminescence testers and various other tests. Integrated in a small van or a container, the systems are flexible to use and easy to move from one location to another. The mobile systems provide highly accurate measurements with report generation directly on site.

The LED-based light source of our solar simulator is certified according to IEC60904 Ed.3 by TÜV Rheinland (class A+A+A+) . All systems support the new module sizes, based on solar cell size up to G12.

Mobile Lab 5.0

The Mobile Lab 5.0 is designed for use directly in the field. The new, even more compact, system offers an A+A+A+ LED Sun Simulator Ed. 3 for power and IV curve measurement and a high-resolution electroluminescence inspection in one. Integrated, e.g. in a van or a container, you have many important measurements directly on site. With the Mobile Lab 5.0 you can reliably find low-power modules, hidden defects (micro-cracks, inactive areas  etc.) and defective diodes.

Laborsystem zur Solarmodultestung

Mini Lab 4.0

This cost-effective laboratory system offers you high-quality power and IV curve measurements as well as high-resolution electroluminescence images despite lower initial costs. This system also uses the TÜV certified MBJ LED light source according to IEC60904 Ed.3. It can be used in a laboratory or directly on site, set up in a container.

Elektrolumineszenz-Testsystem für lose oder eingebaute einzelne PV-Module

MBJ Mobile EL

The MBJ Mobile EL is a high-resolution electroluminescence test system for loose or built-in individual PV modules. The components of the system are stored space-saving in a flight case, so nothing stands in the way for a worldwide use for incoming goods inspection or the examine of individual, built-in modules.

MBJ PV-Module Judgment Criteria

Classification catalog for solar modules

Module Judgment Criteria

This is the 5th revision of the MBJ PV-Module Judgement Criteria catalog. The 5th revision was published in December 2022. It now includes new PV module technologies, such as cell design improvements, multi-bus bar technologies, and half-cut / tripple-cut cell designs. Since the new cell and module designs also affect the rating, the classification tables have been revised. Use the link below to download your copy of the criteria catalog. The file is provided in English.
