Stark Solar Semi is engaged as Owner's Representative, Execution Partner, and Manufacturing Enabler for a 1.3 GW n-Type TOPCon solar cell manufacturing facility in Hyderabad. This is the company's flagship engagement and the most advanced project in the portfolio — currently under active execution. The facility will produce G12R cut cells using LPCVD-based TOPCon technology, with post-cut Electroluminescence and Power Detection (EPD) as a key quality differentiator.
Stark's scope
- Technology selection and cell architecture advisory
- Equipment procurement and OEM negotiation
- Factory layout, process-flow and cleanroom design
- Utility and infrastructure planning (UPW, gases, HVAC, ETP)
- Installation supervision and commissioning management
- Quality systems, yield engineering and ramp-up support
- Workforce planning and training architecture
Technical differentiators
- LPCVD-based TOPCon process — higher passivation quality and long-term efficiency stability
- Post-cut EPD — full electroluminescence and power testing after cell cutting, not before
- G12R format — optimised for next-generation module architectures and higher energy density
- Integrated MES and SCADA — real-time traceability from wafer-in to cell-out
- Designed for ALMM List-II eligibility from day one
Project outcomes
- Fully operational 1.3 GW cell line — commissioning through steady-state production
- ALMM List-II certified facility contributing to India's domestic manufacturing base
- Replicable factory blueprint for future capacity expansion
- Trained Indian workforce capable of sustaining operations independently
- Demonstration of Stark Solar Semi's end-to-end execution model at scale
