By applying a forward bias current to solar panels and capturing the resulting infrared electroluminescence emission with a high-resolution camera, this EL tester reveals hidden defects that are completely invisible to the naked eye. It is an indispensable quality control tool in any solar panel production line, ensuring that only defect-free modules reach the end customer.\u003c\/p\u003e\n\u003cp\u003eThe OEL-S2400 is capable of detecting a wide range of critical defects including microcracks, cell breakage, black spots, mixed wafers, process defects, cold solder joints, and virtual welding issues. With its high-resolution 4928 x 3264 imaging sensor, super-white tempered glass sample stage, and intelligent defect classification software, this machine delivers fast, accurate, and repeatable inspection results. It supports solar modules up to 2600mm x 1500mm in size, making it compatible with all mainstream module formats including G1, M6, M10, M12, MBB, PERC, TOPCon, HJT, and shingled modules.\u003c\/p\u003e\n\u003cp\u003eWhether you are building a new solar panel production line or upgrading your existing quality control process, the Ooitech OEL-S2400 EL Defect Tester provides the reliability and precision you need to maintain the highest manufacturing standards.\u003c\/p\u003e\n\u003cp\u003eWatch our full MBB solar panel production line in action on our YouTube channel: \u003ca href=\"https:\/\/www.youtube.com\/ooitech\"\u003eOoitech YouTube Channel\u003c\/a\u003e.
