Solar Panel Ribbon Tabbing Wire Soldering Strip for DIY solar cell width 1.5mm thickness 0.2mm

The more information of the PV Soldering Strip Tabbing Wire as below:

1. About PV Ribbon:

PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.

• Tabbing Ribbon: it is commonly connects the positive and negative sides of the cells in series.
• Bus bar Ribbon: it is concentrate the cell stringing into junction box and channels electrical current.

2. The Core Technology:

• Forming of round wires to flat wires through drawing and rolling
• Heat tretment
• Hot-dip tinning
• Precise spooling

3. Features and Applications:   

The item (tin coated copper welding ribbon) is based on size of Width*Thickness: 1.5*0.2 mm (it also can be 1.5-2.5mm * 0.08-0.25mm as your option),

sale as per lot, 2kgs/lot.
