What’s Included: A Snapshot of the Bill of Equipment
A turnkey solution includes all the equipment needed to transform raw materials into finished, certified solar modules. Our 1200 MW gigafactory line is a fully integrated system. Key components include:
- Multi-Stringer System: A state-of-the-art stringer configuration with a combined throughput of 43,200 cells per hour.
- Automated Layup & Bussing: Fully robotic systems for precise matrix assembly and interconnection, eliminating manual error.
- 24 High-Capacity Laminators: Working in parallel to process 48 modules per cycle, ensuring a continuous flow without bottlenecks.
- Robotic Framing System: Automated framing, sealing, and curing for perfect structural integrity and weather resistance.
- Automatic J-Box Installation: High-speed junction box attachment and potting for reliable electrical connections.
- Inline Testing & Simulation: Integrated EL and Hi-Pot testers, plus industrial-grade sun simulators for quality assurance on every module.
- Advanced Quality Control: A network of inline QC systems fully integrated with the MES for real-time process monitoring and data logging.
- Integrated Logistics: A complete system of conveyors, buffers, and smart warehousing to manage material flow from start to finish.
Line Layout & Operations
The 1200 MW line is designed as a smart factory, where the workflow revolves around a central MES that orchestrates every machine, robot, and conveyor. This level of integration delivers full operational transparency and control.
Extensive robotics and automation keep staffing requirements minimal, with a typical shift needing only around 10 operators. Their roles shift from manual labor to supervision, quality control, and system oversight. Integrated sensors support predictive maintenance schedules, while MES dashboards provide management with a complete, real-time view of production efficiency, material consumption, and quality metrics.
Investment, OPEX & ROI
A gigafactory of this scale requires a significant capital expenditure (CAPEX), but it is engineered for the lowest possible operational expenditure (OPEX) and cost-per-watt, creating unparalleled economies of scale.
While the line can achieve a maximum theoretical output of 1200 MW per year, a typical operational year with planned maintenance yields approximately 960 MW. The return on investment is driven by several key factors:
- 24/7 Continuous Production: The system is built with industrial-grade components for constant, reliable operation.
- Economies of Scale: High-volume purchasing of raw materials and optimized energy consumption significantly lower the cost of each module produced.
- Future-Proof Design: The line is already equipped to handle next-generation cells, including tandem technology, protecting your investment for years to come.
This level of investment warrants a detailed financial discussion. We are ready to help you model the potential returns based on your specific project parameters.
