Fully automatic tabber and stringer machine with patented innovative hybrid soldering system which allows to solder the photovoltaic cells without thermal stress.
The machine can be interfaced with Automatic Layup Systems for an automatic Pickup & Positioning of the Solar cells on the Glass.

  • Breakage less than 0.2%
  • Patented hybrid soldering technique
  • Works with perc, hit, bi-facial, mono and poly cells
  • Flipper on unload belt
  • Quick and simple production & ribbon change

  • 4 bus bar standard soldering
  • Works with 5”, 6” & cut cells
  • 3,5,6 bus bar available
  • Suitable for bipv modules
  • Low cost of spare parts and consumables
