Sunwire - Photovoltaic Ribbon
From 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.
Products Details
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.
