MBJ Mobile EL

The MBJ Mobile EL is a lightweight, easy-to-use system for high-resolution in-situ electroluminescence module inspection of loose or already installed solar modules. With the MBJ Mobile EL, hidden defects - such as micro-cracks and inactive areas - can be quickly and reliably identified on site. Dismantling the modules for EL testing is no longer necessary! With the help of the intuitive software, evaluation and reporting is easy to perform.  

EL imaging of solar modules in installed condition is done at night. For loose modules, a room darkened against sunlight is sufficient to use the system also during the day, for example for incoming goods inspection.
