MBJ Solutions together with TÜV Rheinland develop a mobile PV laboratory

The PV TravelLab is the first mobile laboratory for testing photovoltaic modules that can be used worldwide / It contains a certified LED sun simulator according to IEC 60904-9 Ed.3, as well as a high-resolution electroluminescence tester

(PresseBox) - T and can be used worldwide. Unlike other mobile laboratories, the PV TravelLab can easily be transported by plane as oversized baggage.

With this system, Ts. The PV TravelLab is designed to test 150 to 200 PV modules per day. The test results are available immediately after the test. Quality problems can thus be recognized at an early stage. There is also no need for complex module transports and the sample size can easily be adapted when need arises.

?As a technology leader in the field of PV module tests, we have very high demands on our project partners. With MBJ we have found a reliable and competent company to implement our challenging specifications? says Dr. Werner Herrmann, Senior Expert PV Power Plants at T

State of the art measurement technology

The PV TravelLab combines the latest measurement technologies for solar modules that are currently available on the market. The A+ A+ A+ LED light source, certified according to IEC 60904-9 Ed.3, ensures power measurements with very low measurement uncertainty, even with new PV module technologies. With a measuring range of 0-250V and 0-20A highly efficient crystalline PV modules as well as thin-film modules can be measured. High-capacity PV modules with PERC or heterojunction (HJT) solar cells are tested on the basis of the "Dynamic I-V" procedure patented by T

For the EL measurement the PV module is moved in its roller mounted frame to the test position above the EL cameras. Two 5 megapixel cameras generate an overall module image in which cracks or broken cells can be found quickly. Problems in the connection of cells or an induced degradation like PID or LeTID can also be seen in the image. With the sensitive cameras, an EL analysis at only 10% of the nominal short-circuit current is also possible.

The system includes a computer controlling the hardware. It also runs the evaluation software. The measurement results are directly available for a detailed evaluation on site. The only requirement: an on-site test room that can be darkened, for example an empty freight or office container.
