FlexMod: Flexible, highly automated PV module production

Cutting table for automated cutting of lamination and back-sheet films using a CO₂ laser. Milling head for processing metals and wood, for example.

 Dimensions of the films:

• Length: max. 300 cm
• Width: max. 180 cm

With the stringer, solar cells (PERC or TOPCon) are automatically connected in series with round wires up to 2.4 m in length.

Currently we can process the following cell formats:

• M2 half cells with 12 busbars
• M6 half cells with 9 busbars
• M10 half cells with 10 busbars
• M12 half cells with 12 busbars
• Other formats on request

The handling robot automatically removes the solar cell strings from the stringer and automatically places the cell matrix. The cell matrix is also cross-connected using a robot and induction soldering head.

Our vacuum laminator has two membranes and two heating plates, so that everything from standard glass backsheet modules to 3D-shaped special modules for building or vehicle integration can be laminated.

 Module size:

• Length: max. 240 cm
• Width: max. 140 cm
• Height: max. 10 cm

Temperatures: both heating plates maximum 180 °C

Small laboratory laminator with a lower heating plate and an upper membrane. The lower heating plate has active water cooling.

 Module size:

• Length: max. 150 cm
• Width: max. 100 cm
• Height: max. 3 cm

Temperature: max. 175 °C

To evaluate processes, cells can be interconnected manually or automatically using

• Contact soldering
• Hot air soldering
• Induction soldering
• Ultrasonic soldering
• Laser welding
• Conductive bonding

• Adhesive bonding of PV modules to various surfaces
• Setting of junction boxes
• Framing of modules up to 240 cm x 140 cm
