The teamtechnik Group, international market leader in the stringer technology segment, presents its STRINGER TT1200 HS which solders solar cell strings in a 2.5 second cycle on just one track. It thus outpaces its predecessor by 200 cycles and is currently the fastest single-track stringer system on the global market. A single track means one single soldering process per stringer, less complexity, a lower requirement for replacement parts and fewer operators.
With a proven availability at over 95%, the system ensures stable production 24 hours a day, seven days a week. "Our competitors' machines only achieve the performance of STRINGER TT1200 HS with two tracks. We are offering our customers a solution which is currently unique and successful on the market in terms of speed, availability and breakage rates," says Stefan Rosskopf, CEO of the teamtechnik Group.
teamtechnik will be giving a live production demonstration at the trade fair PV-Show in Shanghai, on stand E3-350. Every day at 10 am, 12 noon, 2 pm and 4 pm, the STRINGER TT1200 HS will be soldering high-quality solar cell strings with IR light technology. teamtechnik specialists will provide a commentary on the whole process and highlight important system features.
1400 cycles/hour and extremely low breakage rates
teamtechnik uses a unique design of hold-down device in its systems to separate the actual soldering process from the cell-handling process. This allows teamtechnik to ensure 1400 cycles/hour, with a cycle time of 2.5 seconds with just one track. This hold-down device also ensures a safe process and perfect string geometry. At the same time, it guarantees extremely low breakage rates – from 0.1-0.3%, depending on the type of cell.
teamtechnik Group has sold stringer systems with a total production capacity of 9 GWp, and is therefore market leader in China as well as worldwide. The company guarantees its customers 24-hour support anywhere in the world. "We can build one machine every day. None of our competitors can achieve this. We can deliver quickly and at an excellent price-performance ratio," says Stefan Rosskopf, elaborating on the customer-oriented service offered by teamtechnik.
Experienced in BC, MWT, 4-busbar and half-cells
The distinguishing feature of the STRINGER TT 1200 HS is its modular and standardized structure. This makes it possible to adapt new cell technologies to the system which has become widely established throughout the world. teamtechnik specialists have successfully tested and optimized BC, MWT, 4-busbar and half-cells plus adhesive technologies in the company's own center of competence and brought them into series production. The first systems have already been shipped. The center of competence finds the best welding and connection options for standard and special cells and optimizes them further – a service much appreciated by customers worldwide.
