Where is the Solar PV Round Wire Machine suitable for use

      The Solar PV Round Wire Machine is mainly used for efficient and low-cost production of photovoltaic modules using round ribbons, with a focus on high reliability, low stress, and high cost-effectiveness.

1、 Core application scenario (photovoltaic module manufacturing)

1. Mass production line for mainstream high-efficiency solar cells (PERC/TOPCon/HJT)

MBB (Multi Main Gate)/SBMB (Super Multi Main Gate) components: compatible with 2-20BB thin gate line design, circular solder strips (diameter 0.26-0.32mm) can reduce shading area, lower resistance, and improve light absorption, resulting in significant power gain of the components.

Core advantages: low welding stress, no virtual welding, anti hidden cracking, and long-term reliability superior to flat welding strips.

2. Double glass/double-sided/transparent backplate components

Optical gain: The reflected light from the circular line is reused, and the power generation efficiency of the double-sided component is improved both before and after.

Structural adaptation: Double glass structure without flexible backboard, uniform distribution of circular line stress, and less prone to cracking during lamination/transportation/installation.

3. Large size/thin wafer (182/210mm, N-type thin wafer)

Preferred for anti hidden cracking: Thin films (100-120 μ m) are prone to stress damage, with small circular contact points and stress dispersion, greatly reducing the welding/lamination cracking rate.

4. Low to medium cost/distributed photovoltaic modules

High cost-effectiveness: Circular production technology is simpler, material utilization is higher, equipment investment is lower, and it is suitable for cost sensitive scenarios such as household use, village level, and industrial and commercial roofs.

5. Special customization/flexible components

Lightweight/Flexible Components: Round wires have good flexibility and resistance to bending, suitable for BIPV, flexible photovoltaics, and curved installation scenarios.

6. Research and development/experimentation/small-scale trial production

Laboratory/Pilot Line: Used for verifying new materials, processes, and battery structures, with adjustable parameters, strong compatibility, and low trial production costs.

2、 Adapt to the scale of the production line

Small (<50MW): Semi automatic circular wire machine, flexible trial production, multi specification small batch.

Medium size (50~300MW): Fully automatic circular wire 4000/7200 type, balancing efficiency and stability.

Large scale (500MW~1GW+): High end round wire machine+integrated cutting and welding, high-speed mass production, high consistency.

3、 Why choose circular wire machine (compared to flat wire)

Stronger reliability: excellent stress distribution, fatigue resistance, resistance to cold and hot cycles, and longer lifespan.

Thin/large-sized friendly: low hidden cracking rate and high yield.

Optics/power generation are better: reduce shading, increase reflection, double-sided gain.

Better cost: lower equipment/material/maintenance costs.

Wide process compatibility: PERC/TOPCon/HJT fully compatible, MBB/SMBB compatible.

4、 Typical terminal applications

Distributed photovoltaics: residential/commercial roofs (high reliability, low cost, long lifespan).

Ground power station: large photovoltaic base (high power generation, low LCOE, high stability).

BIPV: Building photovoltaic integration (anti cracking, adaptable to curved/irregular surfaces).

Vehicle mounted/portable photovoltaics: lightweight, shock resistant, and flexible.
