EL test

EL Test

The Module inspection system has been developed for inspecting solar modules before and after the lamination process. The system detects micro cracks in the bulk material, shunts, defects in the front grid electrodes and low efficiency areas in the cells of the panel. This system provides capabilities to achieve lower production cost, higher process yield and ultimately more customer satisfaction through continuous high module quality.

The solar module is loaded with the sunny side down into the EL inspection system.
