Production & QC
DAH solar - established in 2009 with 1GW solar module production capacity
Covers 58,000 sqm and has 350 employees. DAH solar is a national high-tech enterprise specializing in R & D and manufacturing of solar modules, have own engineer team for complete set solar system design for residential and commercial projects.
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
EL Testing
Use the mirror to inspect the appearance of the solar modules before lamination, and repair them if they are defective;
Visual Inspection
Through the turning machine, completely inspect the solar panel after lamination, and record the defects and feedback to the previous process
Flash Testing
Including temperature, power, voltage, current and other related tests, ensure 0~+5W Positive Power Tolerance
Safe Packaging
1st
Put the solar panel vertically on the customized pallet, and protect each sides of solar panel with a corner-protector.
2nd
First use the packing belt to stabilize the solar panel for the first time, with the bar code upward for easy searching.
3rd
Put a customized logo carton on the bundled solar panel and seal it.
4th
Use packing belt for the second strapping,with corner-protector protect the carton from damage.
5th
Put into warehouse when packing is completed, To make full use of the container space, 4-6 pcs solar panels are added on each two pallets to reduce transportation costs while ensuring safety.
6th
Wrap the outer packaging with plastic film before transportation to ensure that it will not get wet.
