2BG Srl, in collaboration with SCHLENK, has developed the technology to interconnect automatically the solar cells with ribbon SCHLENK LHS in its own Tabber&Stringer. This system called “DRS” (Double Ribbon Soldering) ensures the maximum flexibility in the photovoltaic modules production in fact, it allows to use in addition to the common ribbon, even the SCHLENK LHS and exploit all its benefits in terms of efficiency. “DRS” has been developed for being installed on 2BG Tabber&Stringer models, already on stream by its customers.
