Solar PV Ribbon & Busbar Wire for Solar Cells Soldering

About Solar 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.

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)
