Full Advanced Automated Production


Solar cell Welding

Use automatic welding machine to connect solar cells in series
All the solar cells are made by top class brand, like TW Solar, Longi Solar

Automatic typesetting machine

After setting up the program according to the requirements of the process drawings, the typesetting machine will automatically typeset the battery string. High precision, high efficiency, low defect rate


Automatic welding

Automatic laying of EVA, backing, automatic cutting of excess backing material
100% automation of the entire production process

Visual Inspection

Through the turning machine, completely inspect the solar panel after lamination, and record the defects and feedback to the previous process


EL Testing

Use the mirror to inspect the appearance of the solar modules before lamination, and repair them if they are defective;

Flash Testing

Including temperature, power, voltage, current and other related tests, ensure 0~+5W Positive Power Tolerance


Our Project


Safe Packing
