Automatic Solar Module EL and AOI Appearance Tester

Applications:

The EL detection system consists of 4 near-infrared cameras(high quality 0.4mm/pixel), and the appearance AOI detection system consists of another 4 visible light cameras(high quality 0.09mm/pixel), which collect EL infrared images and visible light images respectively.

The complete EL image and visible image of the solar panel are obtained through multi-station image acquisition and multi-camera image splicing,. The system has high imaging quality and small window to view details, which is conducive to the determination of EL defects and appearance defects of solar panel.

The EL detection and AOI appearance detection of PV panel can be independent detection system or combined into a set of detection system.
