MBJ Mobile Lab - now available in the revised 4th generation

The quality of solar modules is decisive for the economic success of a photovoltaic system. Whether during the construction, acquisition or maintenance of a solar power plant, a detailed inspection of the modules is probably the most important measure to secure investment and long-term yield.

With the Mobile Lab 4.0 from MBJ Services you can test solar modules directly on site. The easily transportable container can be placed for incoming inspection or directly on the strings to be tested. The simple measuring procedure ensures a module throughput of up to 300 modules per day. The integrated LED sun simulator, certified according to the latest IEC 60904-9 Ed.3, ensures measurements that are in no way inferior to those of a test laboratory. In the electroluminescence image, cell damages such as cracks and smallest fractures are directly visible. Additional tests such as a test of the module diodes or a thermographic image provide further information. All results are stored in the included database for evaluation and report generation.   

Offer your customers directly on site the information needed to evaluate their solar park.
