Product Description


Production Process



Solar Cell Welding
Use automatic welding machine to connect solar cells in series
All the solar cells are made by top-class brands.
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.
Solar Panel EL Testing
Use the mirror to inspect the appearance of the solar modules before lamination, and repair them if they are defective.
