Tinned copper wire for photovoltaic module is a micro-type welding material developed for adapting to multiple sets of grid components. The application of tinned copper wire (multi-grid) can effectively reduce the shading area of the component ribbon. On the other hand, the pitch of the gate lines is greatly reduced, even if the cell is cracked, the distance from the fine gate to the main gate line is small, so the influence on the overall power of the module is greatly reduced, thereby ensuring the reliability of the output power of the component.

Note: we can customize specifications of the 12BB according to your requirements.
