What is PV Ribbon-Photovoltaic Ribbon
|
Photovoltaic Ribbon | Solar Ribbon Solar tabbing wire | Solar busbar |
| Photovoltaic ribbon, also known as PV Ribbon 、PV bussing ribbon、solar tabbing ribbon or Solar Ribbon, is a hot-dipped tinned copper flat conductor that collects the current from the photovoltaic cells. It connects the individual solar cells and carries the generated current to the distribution system. |
LEADING PV RIBBON SUPPLIER SINCE 2012 |
Raytron was founded in 2012 and started its business with the development of copper-rolled flat ribbon wire. |
After 10 years of persistent efforts, Raytron has become the most professional manufacturer of high precision copper & copper-clad aluminum flat ribbon wire & strip in China and one of the very few manufacturers in China that can produce flat wire & strip with a width to thickness ratio of higher than 100 times and copper strip & flat ribbon wire with ultra-low yield strength below 110Mpa. High dimensional accuracy and straightness are also guaranteed. |
With 10 high-precision 4-link rolling mills and an annual production capacity of 10,000 tonnes, Raytron is the largest manufacturer of rolled copper strips & flat ribbon wires for Photovoltaic Ribbon & Solar Busbars in China. |

2 Types of PV Ribbon
Interconnect/Tabbing Ribbon | Busbar Ribbon
| TYPE 1 | |
| INTERCONNECT RIBBON /TABBING WIRE Interconnect ribbon/Tabbing wire carries the generated current from all the PV cells to the bus bar. | |
| Thickness 0.07mm-0.2mm | Width 1mm-3mm |
| Base Metal Cu | Al | CCA | Solder Type Sn; SnPb; SnAg; SnCuAg; SnPbAg; SnBi; SnBiAg |
| Type 2 | |
| BUS BAR/ BUSSING WIRE Bus bar/ Bussing wire is the wire converging the accumulated current to the junction box or electrical distribution system. | |
| Thickness 0.07mm-0.5mm | Width 3mm-6mm |
| Base Metal Cu | Al | CCA | Solder Type Sn; SnPb; SnAg; SnCuAg; SnPbAg; SnBi; SnBiAg |
6 key factors for Choosing
PV Ribbon
PV Ribbon is the basic component of a photovoltaic system; therefore, its quality is very
important for solar panels’ lifetime, function, and efficiency.
 Material The widely used base material of PV ribbon is CDA102 copper which offers at least 100%IACS conductivity. Different Aluminum alloys as well as Copper Clad Aluminum are also available. |
 Tin plating Tin layer composition and coating thickness are important parameters that affect the solder strength and performance of the PV panels. |
 Yield strength The yield strength is the minimum amount of stress required to permanently deform the PV Ribbon. It is an important parameter because if the yield strength of the PV Ribbon is too high, it can put a lot of stress on the panel itself and cause it to break. |
Camber
To avoid missed bonds, PV ribbon must be straight without camber.
Elongation
High Elongation= High Ductility = High Module reliability
Winding
Minimize Camber, Aviod tangle, Maintain Yield Strength
