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 laying of EVA, backing, automatic cutting of excess backing material
100% automation of the entire production process
Through the turning machine, completely inspect the solar panel after lamination, and record the defects and feedback to the previous process
Use the mirror to inspect the appearance of the solar modules before lamination, and repair them if they are defective;
Including temperature, power, voltage, current and other related tests, ensure 0~+5W Positive Power Tolerance
