PV Ribbon | Solar Busbar

What is PV Ribbon-Photovoltaic Ribbon

Photovoltaic Ribbon | Solar Ribbon

Photovoltaic ribbon, also known as PV 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.

PV BUSBAR RIBBON FROM RAYTRON

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.

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
