Photovoltaic welding ribbon<\/a>The quality directly affectsPhotovoltaic modules<\/a>The performance and life of the soldering strip are as follows:<\/p>\n

1. Material composition<\/strong><\/p>\n

Purity: High-quality solder strips should use high-purity copper or aluminum, and low impurity content can ensure good conductivity.<\/p>\n

Plating: Tin or silver-plated solder strips can improve oxidation resistance and ensure long-term electrical contact stability.<\/p>\n

2. Resistance value<\/strong><\/p>\n

Low resistance: High-quality solder strips should have lower resistance values, reduce series resistance losses, and improve current conduction efficiency.<\/p>\n

3. Thickness and width<\/strong><\/p>\n

Consistency: The thickness and width of the welding strip should meet the standards. Too thin thickness may lead to insufficient strength, and mismatched width will affect the welding effect.<\/p>\n

4. Hardness<\/strong><\/p>\n

Adaptability: Choose the appropriate hardness according to the welding method. Manual welding generally requires a softer welding ribbon, while automatic welding is suitable for harder welding ribbons.<\/p>\n
