Structure

We produce custom engineered solar tabbing and  bus wire helping to attain the highest efficiencies possible for each unique module design.   Our Research and Development team can assist you with your needs evaluation and our world-wide manufacturing facilities are strategically located for large volume production.

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.

Feature

1,Good solderability
2,Good straightness
3,Low yield strength
4,Low Melti

The Flux should be compounded and processed in such a manner as to be uniform in quality and should be free from deleterious material and other details that will after life serviceability or appearance.
