PV Ribbon Production Line

Complete Turnkey PV Ribbon Manufacturing Line for Solar Cell Interconnection, Busbar & MBB Production, integrating copper wire drawing, annealing, rolling, surface treatment, and precision winding into one continuous automated system.

What is PV Ribbon Production Line

A PV ribbon production line is an advanced system featuring a copper wire tinning process, specifically designed to manufacture solar interconnection ribbons, busbar ribbons, and MBB round wire ribbons—critical components in photovoltaic modules. By incorporating the latest technology, this production line enhances current transmission efficiency within solar cells, optimizing power generation. We offer turnkey solutions that include innovative process design, seamless equipment integration, and layout optimization, ensuring a highly efficient and reliable production process from start to finish.

PV Ribbon Machine Types and Typical Specifications

Sky Bluer Environmental Technology Co., Ltd. designs PV ribbon production lines mainly for the manufacturing of three key product types:

Round Wire Ribbon (RWR)

Round wire ribbon is used in advanced PV module designs to reduce shading and improve module efficiency.

Typical finished diameter: 0.26 mm (after tin coating)
Tin coating thickness:
Single side: 0.015 mm
Total (double side): 0.03 mm
Application: high-efficiency PV modules
Advantage: reduced optical shading, improved energy output

Interconnect Ribbon (Flat Ribbon)

Busbar ribbon is used to collect current from interconnected cell strings and transfer it to the junction box.

Typical size: 5.0 × 0.30 mm (width × thickness)
Profile: flat (wide cross-section)
Application: current collection and output
Requirement: high conductivity, stable mechanical performance

Busbar Ribbon

Busbar ribbon is used to collect current from interconnected cell strings and transfer it to the junction box.

Typical size: 5.0 × 0.30 mm (width × thickness)
Profile: flat (wide cross-section)
Application: current collection and output
Requirement: high conductivity, stable mechanical performance

Production Process Overview

CRM PV ribbon production line is a fully automated and continuous manufacturing system designed to convert copper wire into high-precision solar ribbons for photovoltaic interconnection, busbar, and MBB applications.

The process includes wire drawing, annealing, precision rolling, surface treatment, plating, and controlled winding, ensuring stable conductivity, tight dimensional tolerance, and consistent surface quality for reliable solar module performance.
