The photovoltaic welding strip rolling mill is a key equipment specifically used for producing photovoltaic welding strips. Its core function is to process metal wires (mainly copper strips) into photovoltaic welding strips with specific thickness, width, and cross-sectional shape through rolling technology. As a "bridge" for current conduction between solar cells, photovoltaic ribbon is an indispensable material in the production of photovoltaic modules. Therefore, the application fields of photovoltaic ribbon rolling mills are highly tied to the downstream demand for photovoltaic ribbon, mainly concentrated in the following industries:
1、 Photovoltaic new energy industry (core application areas)
This is the most important and direct application industry of photovoltaic strip rolling mills, running through the midstream of the photovoltaic industry chain.
Photovoltaic module production: Photovoltaic ribbon is the core auxiliary material of photovoltaic modules (composed of solar cells, glass, backplate, encapsulation film, etc.), used to connect different cells and form a current path. The welding strips produced by the photovoltaic welding strip rolling mill must meet strict requirements for conductivity, weldability, flexibility, etc., which directly affects the power generation efficiency and reliability of photovoltaic modules. Therefore, all enterprises engaged in the production of photovoltaic modules must have their upstream photovoltaic ribbon manufacturers equipped with photovoltaic ribbon rolling mills to ensure a stable supply of ribbon.
Specialized production of photovoltaic welding strips: In the photovoltaic industry chain, there are enterprises that specialize in providing photovoltaic welding strips for component factories (such as welding strip manufacturers). These enterprises are the main purchasers of photovoltaic welding strip rolling mills, which process copper substrates into welding strip products that meet different component specifications (such as conventional components, high-efficiency stacked tile components, double-sided components, etc.) through rolling mills.
2、 Related supporting industries in the photovoltaic industry chain
Photovoltaic equipment manufacturing support: Some photovoltaic equipment integrators will include photovoltaic welding and rolling mills in the supporting equipment system when providing overall solutions for photovoltaic module production lines, providing "one-stop" equipment services for downstream component factories. At this time, the rolling mill serves as a part of the supporting equipment and serves the photovoltaic module production process.
Copper processing extension industry: The substrate of photovoltaic welding strips is high-purity electrolytic copper. Some copper processing enterprises will extend the industry chain and enter the production of photovoltaic welding strips. At this time, photovoltaic welding strip rolling mills have become the key processing equipment from copper materials to welding strip products, serving the subdivision field of photovoltaic auxiliary materials.
3、 Other potential related industries
Although the original design intention of the photovoltaic welding strip rolling mill is to produce photovoltaic welding strips, its core function is precision rolling of metal strips. In some sub fields with similar requirements for strip size accuracy and surface quality, there may be a small number of adaptive applications (which need to be adjusted according to specific processes), such as:
Production of strip for small electronic connectors: Some micro electronic connectors require extremely thin and high-precision copper strips for their contact plates. If the specifications are similar to photovoltaic welding strips, after adjusting the equipment parameters, photovoltaic welding strip rolling mills may be used for rolling such strips.
Precision metal jewelry processing: For jewelry processing with specific size requirements for some thin metal strips (such as copper and silver strips), it may be temporarily rolled using a photovoltaic welding strip rolling mill (but not the main application scenario).
