0BB Stress-free Stringer
0BB Stress-free Stringer
Stringer model: GPV-HJ-WYL08
Introduction: This 0BB Stress-free Stringer can complete the interconnection process of non-main grid battery cells (TOPCon, HJT, etc.), with high efficiency, good curing quality, and reliability.
0BB cells has a promising future due to its high energy yield efficiency, but the stringer required is different from those for MBB and SMBB cells.
The reliability of 0BB stress-free stringer developed by Auto-ONE has been proven in various massive production lines of Chinese solar panel manufacturers. 70% of the installed 0BB stringers are done by Auto-ONE around the globe. Our 0BB stringer is the absolute market leader around the world for inter-connecting pv cells in industrial scale applications.
The others may propose their own solutions based on laboratory experiences and PPT presentation, but Auto-ONE 0BB stringer has gain its reputation in real massive production line.
