Production & QC
DAH solar - established in 2009 with 1GW solar module production capacity
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
Use the mirror to inspect the appearance of the solar modules before lamination, and repair them if they are defective;
Through the turning machine, completely inspect the solar panel after lamination, and record the defects and feedback to the previous process
Including temperature, power, voltage, current and other related tests, ensure 0~+5W Positive Power Tolerance
Put the solar panel vertically on the customized pallet, and protect each sides of solar panel with a corner-protector.
First use the packing belt to stabilize the solar panel for the first time, with the bar code upward for easy searching.
Put a customized logo carton on the bundled solar panel and seal it.
Use packing belt for the second strapping,with corner-protector protect the carton from damage.
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.
Wrap the outer packaging with plastic film before transportation to ensure that it will not get wet.
