Maximize Your Solar Panel Efficiency with MBB Solar Cell Welding Stringer - Industry-Leading Technology for Precise and Efficient Soldering

Main Function

MBB solar cell welding stringer is a fully automatic machine used to non-destructively cut the mono-Si or poly-Si cells and then solder them into a string. Normally it can work with 156-230mm (3BB-20BB) cells. The cell cut module can cut cells in half, or cut cells into three strips after upgrade. The soldering module can be upgraded for 156-230mm (full, half-cut, 1/3-cut) cells. With the use of PLC, servo, SCARA robot, industrial image processor system and other advanced automation technology, the entire process from cell feed to string outlet is fully automated.

Basic Information

 

 

 

Uptime

 

 

 

≥95%

(1 - unscheduled downtime/24H), unscheduled downtime refers to   the time when the equipment   malfunctions   or is shut down unexpectedly.

 

 

 

 

 

 

Speed

18Xmm cells: 3BB-12BB   Half-cut≥6800 strips/hour

18Xmm cells: 13BB-20BB

Half-cut≥6000 strips/hour

 

230mm cells: 3BB-12BB

Half-cut,   1/3-cut  ≥6800 strips/hour   230mm cells: 13BB-20BB

Half-cut, 1/3-cut    ≥6000strips/hour

 

 

 

The speed depends on the solder   process. If the required   solder time is too long, it may affect the production speed.

 

 

 

Cell Cracks

 

161mm to 171mm cells:   Mono-Si ≤0.2%;

171mm to 230mm cells:   Mono-Si ≤0.25%;

Popular Grade A cell,   thickness

≥17m

Cell crack ratio = (cracked cells + micro-cracked cells)/total number   of soldered cells × 100%
