When choosing copper clad aluminum (CCA)Photovoltaic welding ribbon<\/a>When choosing a copper clad aluminum photovoltaic ribbon, multiple factors need to be considered to ensure that it is suitable for a specific photovoltaic application. Here are some key considerations and how to choose the right copper clad aluminum photovoltaic ribbon:<\/p>\n

1. Copper layer thickness of copper clad aluminum welding strip<\/p>\n

Selection criteria: The thickness of the copper layer directly affects the conductivity of the solder strip. A thinner copper layer may lead to insufficient conductivity, increase contact resistance, and affectPhotovoltaic modules<\/a>In order to ensure that the electrical performance of the welding strip meets the standard, the welding strip with appropriate copper layer thickness should be selected, and strict process control is usually required to ensure the uniformity and stability of the copper layer.<\/p>\n

Application scenarios: For photovoltaic projects with high power output, a thicker copper layer is required to ensure good conductivity under high current load.<\/p>\n

2. Bonding strength between copper and aluminum<\/p>\n

Selection criteria: The bond strength between copper and aluminum determines the mechanical properties and long-term stability of the welding strip. Poor bonding may cause material delamination or shedding, increasing the risk of failure. Copper-clad aluminum welding strips that use advanced technology to ensure a strong bond between copper and aluminum should be selected.<\/p>\n

Application scenario: If the photovoltaic system needs to operate for a long time in a harsh environment (such as high temperature, humidity, etc.), it is particularly important to use high-quality copper-clad aluminum welding strips.<\/p>\n

3. Conductive properties<\/p>\n

Selection criteria: The conductivity of copper-clad aluminum welding strips should be close to or reach the standard of pure copper welding strips. Welding strips with poor conductivity will cause power loss, heating and reduced efficiency. The conductivity of the welding strip should be confirmed when selecting, especially in high-load, high-current applications.<\/p>\n

Application scenario: For photovoltaic systems that require high power transmission efficiency, it is very important to choose copper-clad aluminum welding strips with good conductivity.<\/p>\n
