Line Layout and Operations
The 800 MW line is designed as an end-to-end smart factory. From the moment raw materials enter the facility to the final packaging of finished modules, every step is managed by a network of robotics, conveyors, and a central MES. This integrated system provides complete control over the entire production workflow.
The high level of automation significantly reduces staffing requirements to just 10–12 operators per shift. Their roles are focused on supervision, material replenishment, and quality oversight rather than manual assembly. The MES enables digital monitoring of all key performance indicators, provides real-time quality control, and supports predictive maintenance schedules to maximize plant availability.
Investment, OPEX, and Return on Investment
While the initial capital expenditure (CAPEX) for an 800 MW gigafactory line is substantial, the entire system is optimized to deliver the lowest possible cost per watt. This is the critical metric for profitability and market competitiveness in utility-scale and export markets.
Engineered for continuous 24/7 operation, the line can achieve a typical output of 650 MW or reach its maximum rated capacity of 800 MW per year, depending on operational efficiency and module specifications. The resulting economies of scale dramatically reduce operational expenditures (OPEX) per unit, ensuring a strong and accelerated return on investment.

The Upgrade Path: Scaling Beyond 800 MW
An 800 MW line is a powerful platform for growth. Its modular design enables strategic expansion to 1.2 GW and beyond. This is typically achieved by adding more laminators to increase throughput, enhancing inline logistics to handle higher volumes, and integrating next-generation technologies like tandem cells as they become commercially viable.
This forward-looking approach ensures your investment is future-proof and can adapt to evolving market demands.
