The global photovoltaic (PV) manufacturing landscape is undergoing a rapid technological transition. As module manufacturers move beyond standard designs to adopt highly efficient cell architectures, production lines must evolve to handle new requirements in interconnection, handling, and encapsulation. At the upcoming RE+ 2026 exhibition, scheduled for November 17–19 at the Las Vegas Convention Center, SC Solar plans to showcase its latest manufacturing technologies designed to address these challenges. Located at Booth N2840, the company will present automation solutions tailored for TOPCon multi-cut, back-contact (BC), and heterojunction (HJT) technologies, alongside complete turnkey factory solutions and localized support systems for U.S.-based manufacturers.

Tailored Automation for Evolving Cell Technologies

The diversification of solar cell architectures requires highly specialized equipment. SC Solar's approach focuses on providing dedicated machinery and line configurations that align with specific manufacturing processes, allowing producers to match their physical setup with their chosen technology path.

TOPCon Multi-Cut Optimization

For Tunnel Oxide Passivated Contact (TOPCon) multi-cut applications, the manufacturing process demands precise handling and welding to maintain high throughput. SC Solar addresses this by combining multi-cut layup welding, ribbon folding, and jumper welding equipment. This integrated setup is engineered to support various cut counts and circuit layouts, ensuring flexibility as manufacturers adjust their module designs.

Back-Contact (BC) Interconnection Solutions

Back-contact technologies, which place all electrical contacts on the rear of the cell to maximize light absorption, present unique assembly challenges. SC Solar has developed specialized printing and curing equipment that works in tandem with stringing solutions designed for HPBC, TBC, HBC, and other BC cell variations. Depending on the specific cell design and process requirements, manufacturers can utilize different stringing methods, including:

  • High-temperature solder paste
  • Low-temperature film bonding
  • Low-temperature dispensing

Zero-Busbar (0BB) Heterojunction (HJT) Integration

Heterojunction technology (HJT) is highly sensitive to thermal stress, requiring specialized low-temperature processing. For zero-busbar (0BB) HJT applications, SC Solar offers dedicated line configurations optimized for both film-based and adhesive-based processes. These configurations integrate film laying, adhesive application, UV curing, and infrared soldering equipment. Additionally, the lines feature specialized lamination solutions designed specifically to protect heat-sensitive HJT cells during encapsulation.

The Turnkey Smart Factory: End-to-End Automation

Beyond individual machine stations, modern PV manufacturing relies on complete factory integration to maximize efficiency and reduce manual labor. SC Solar provides turnkey factory solutions that unite module production, logistics, and digital management into a single cohesive ecosystem.

The physical production line covers the entire manufacturing sequence, including:

  • Glass loading
  • Stringing and layup
  • Lamination and framing
  • Testing and sorting

Logistics and Material Handling

To connect the core production line with the broader factory environment, SC Solar integrates automated material warehousing and unpacking, module packaging, finished goods storage, and truck loading systems. Material transport between production zones and storage areas is handled by automated guided vehicles (AGVs) and rail-guided vehicles (RGVs), reducing physical handling and minimizing the risk of material damage.

Digital Management and AI Quality Control

Digital systems form the backbone of these turnkey factories. A manufacturing execution system (MES) coordinates production schedules and tracks individual modules from the initial order stage through to final shipment. To maintain quality standards, AI-powered inspection systems are deployed at key stages of the production line, providing automated quality control and defect detection. Each factory layout and equipment configuration is customized to fit the client's specific facility, capacity goals, and technology choices.

Localizing Support for the Expanding U.S. Market

Establishing a manufacturing facility requires extensive planning and ongoing operational support. SC Solar assists manufacturers from the initial digital factory design phase—which aligns equipment, floor space, and material flow prior to delivery—through to equipment manufacturing, factory testing, installation, and commissioning. Following setup, the company provides product and material qualification, process optimization, and quality control configuration.

Texas-Based Infrastructure and Operational Optimization

SC Solar has been active in the United States since 2017, having shipped more than 40 production lines to the market. To deepen its commitment to domestic manufacturers, the company established its U.S. subsidiary in 2024.

Operating from a local base, which includes a technical team and a dedicated spare-parts warehouse in Texas, the company provides:

  • Preventive maintenance services
  • Critical spare-parts supply
  • Remote diagnostics

To help manufacturers continuously improve operational efficiency, SC Solar conducts regular reviews of key performance metrics, including downtime, overall equipment effectiveness (OEE), and consumable usage. This localized approach supports the company's broader mission to “Make PV Manufacturing as Easy as Possible” by combining technology-specific automation with comprehensive factory integration.
