Cutting-edge Inspection Equipment

EL Test

The production line adopts horizontal direct photography, using imported SONY camera with 4.608 million pixels, characteristics of recognition accuracy<0.5mm/pixel and shooting time 0.5s and test time 2s/cell string, capable of AI intelligent judgment and click to enlarge, which is convenient to check the type of defects and the working status of the welding machine.

IV Test

The 3A+ class light source adopted and the continuous testability of the same module ≤0.15%. Both single light source and single control system were applied to secure the synchronization of flash during the test. The software can accurately collect and calculate all parameters such as Isc, Voc, Ipm, Vpm, and light intensity.

Automatic Grading

The advanced automatic classification system, which is connected to the intelligent information processing system, can precisely classify solar modules. It can meet the grading needs of all mainstream module types in the industry. Through the automatic image positioning and recognition system, the equipment is driven by servo motor with high-speed, stable and accurate operation.

Solar Module

Fully-compatible intelligent production facilities enable customized modules to meet the diversified needs of customers. Combining 182mm and 210mm cells with MBB & SMBB technology, we provide our customers with high-conversion modules suitable for various application scenarios, and customize the modules according to the needs of our customers to adapt to different regional markets.
