Overview
An EL Inspection / Electroluminescence Inspection) Inspector is a non-destructive testing (NDT) device which detects hidden defects hidden defects by filming the infrared electroluminescent emitted within the cell after applying current on solar cells or modules.
It is a part where it is possible to detect even unstructured defects through self-made AI SW by TWIM and has been applied toward production processes of solar module in North America.
