In the field of photovoltaics, GG produces fully-tinned flat copper wires. These wires are used as interconnecting ribbons and bus wires for the production of photovoltaic modules with monocrystalline or polycrystalline cells.

Both the coating alloy and the mechanical characteristics of the ribbons can be adapted for the specific customer and system requirements regarding their fully automated processes.

We guarantee the lowest tolerances and flawless coating by using state-of-the-art facilities and continuous in-line testing systems.
