What are the applications of photovoltaic welding strip rolling mill in the new energy industry

     As a key equipment in the photovoltaic industry chain, the photovoltaic welding strip rolling mill is mainly focused on the application of photovoltaic new energy in the new energy industry. Its core role is to provide key connecting materials - photovoltaic welding strips - for the production of photovoltaic modules, thereby supporting the efficient operation of solar power generation systems. The specific applications are as follows:

1. Photovoltaic module manufacturing process (core application)

     The core product of the photovoltaic new energy industry is solar photovoltaic modules, and photovoltaic ribbon is the "blood vessel" that connects the internal cells of the modules and achieves current collection. The photovoltaic strip rolling mill processes copper strips and other base materials into base strips of specific thickness, width, and cross-sectional shape (such as flat or semi-circular) through high-precision rolling technology, providing a foundation for subsequent processes such as tin coating (improving conductivity and weldability).

     These solder strips are ultimately used for the series/parallel connection of solar cells in photovoltaic modules, directly affecting the power generation efficiency, reliability, and service life of the modules. Therefore, the photovoltaic ribbon rolling mill is the core equipment in the "auxiliary material production" link of the photovoltaic module industry chain, supporting the manufacturing of various efficient photovoltaic modules such as single crystal, polycrystalline, heterojunction, etc.

2. Construction and operation support of photovoltaic power stations

      Photovoltaic power stations (centralized, distributed) are important scenarios for new energy generation, and their core hardware is photovoltaic modules. The quality of photovoltaic welding strips (determined by the rolling accuracy of the rolling mill) directly affects the long-term stable operation of the components:

     Welding strips with insufficient rolling accuracy may cause hidden cracks in the battery cells, excessive contact resistance, and reduce the power generation efficiency of the power station;

     High quality welding strip (processed by precision rolling mill) can improve the aging resistance, cold and hot shock resistance of components and reduce the operation and maintenance cost of power station.

     Therefore, the photovoltaic welding strip rolling mill indirectly supports the efficient and stable power generation of the photovoltaic power station by ensuring the quality of the welding strip, and is the "implicit support equipment" of the new energy power system.

3. Integration scenarios of new energy storage and photovoltaics

     With the promotion of the "photovoltaic+energy storage" model, photovoltaic modules need to work in conjunction with energy storage systems, and higher reliability requirements are placed on the modules. As the core connecting component of the module, the performance of photovoltaic ribbon (such as conductivity and fatigue resistance) needs to be adapted to the high-frequency charging and discharging scenarios of energy storage systems.

     The photovoltaic welding strip rolling mill can produce high-performance welding strips suitable for the "photovoltaic+energy storage" scenario by optimizing the rolling process (such as controlling the grain structure and flatness of the strip), which helps to ensure the stable operation of new energy storage systems.
