EVO 3000

Stringer Machine for Cut cells

EVO3000 is an evolution of the traditional stringer machine because its unique patent pending concept diversifies it from all other equipment available on the market.
The soldering of the cells is continuous. This technology results in an extremely high flexibility and productivity maintaining a breakage percentage almost equal to 0%.



  1. High soldering quality; more than 2N in peel test over the complete cell surface;
  2. Solders cells from 156x52mm all the way down to 52 x 15 mm with 5, 4, 3, 2 or only 1 bus bar;
  3. Possibility to change cell size in less than 30 minutes;
  4. Automatic change of cell load basket;
  5. Pre and post heating of the cell in soldering phase in order to avoid thermal stress;
  6. Stretching of the ribbon before soldering;
  7. Fluxing directly on the cell;
  8. Special designed for thin solar cells, 160 micron;
  9. Adjustable tab length;
  10. Touch screen with embedded PC;
  11. Troubleshooting online to the touch-screen;
  12. The number of solar cells for the strings is settable from the touch-screen;
  13. Adjustable inter-axis between the cells, max 165 mm;

  1. No pre-treatment of the ribbon is necessary;
  2. This machine has very little need of maintenance and all maintenance work can be performed by the operator without calling Ecoprogetti’s technicians;
  3. Quick remote assistance and supervision via internet;
  4. Predisposed to be interfaced with other equipment
