Sunwire - Photovoltaic Ribbon
Sunwire® is a copper-based flat ribbon used to connect silicon cells electrically and to carry out current in crystalline silicon and thin-film photovoltaic modules. Extra soft Sunwire® reduces cell breakages and reduces electrical resistance in modules. Combined with consistent quality, excellent spooling and straightness, Sunwire improves customers` manufacturing process and final product. Sunwire is also an excellent choice for thin film modules.
Sunwire is rolled from round wire to high precision, annealed to extra soft, plated all-over in hot-dip-tinning process and precision level-wound on returnable spools. All standard dimensions, plating alloys and spool sizes are available.
The latest annealing and plating technology in Sunwire products is completely chemical-free and compatible with new lead-free soldering alloys and saves energy. It was developed to help our customers to improve their production yield and product performance.
Sunwire benefits
