Automatic Bussing Machine DH200-Y — High-Speed Busbar Soldering for Solar Panel Production
The Ooitech DH200-Y Automatic Bussing Machine is a high-performance busbar soldering system engineered for modern solar module production lines. This machine automatically separates string cells from the glass surface, lifts cell strings to a precise height using a grip mechanism, and simultaneously welds panel busbars at the front, middle, and tail positions. Equipped with roll-feeding bus bar technology, the DH200-Y can bend busbars into both U-type and L-type shapes upward, and includes an optional hole-drilling function in the busbar that can be toggled on or off as needed.
Designed to accommodate a wide range of cell formats — including 166mm, 182mm, 210mm, and 230mm cells with 5BB to 20BB configurations — the DH200-Y is the ideal bussing solution for manufacturers producing PERC, TOPCon, IBC, ABC, HPBC, shingled, and MBB solar panels. Whether you are building a new 5MW to 1GW solar panel production line or upgrading an existing facility, this automatic bussing machine delivers the speed, precision, and reliability your factory demands.
