Solar Panel El Defector

We are Making and Supplying Solar Panel El Defectors in Jiangsu, Jiangsu Sheng, China. EL tester is an optical phenomenon and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field.
Microcrack inspection machine for the crystallinesilicon photovoltaic modules and Clear image can be grabbed in a darkroom by sensitive Camera. In this case, EL technology has been used in solar panel's quality inspection.
Defects of Solar Panel / PV Module
- Microcrack
- Broken or chipped solar cells
- Dark area
- Bus-bar connection defects
- Print defects
- Poor contact
- Cell lay up errors
- Pseudo soldering
- Pollution

Solar EL Panel Machine for Crack Detection
KEYLAND solar panel ccd camera el tester uses electroluminescence (EL) measurements to identify microcracks and other invisible defects in modules. The testers use cooled near-infrared CCD (NIR) camera technology to take image for each solar cells in a dark room.
KEYLAND EL TESTERS are available in either stand-alone and in-line configurations and can be easily integrated into any environment from R&D to high volume production.
