Strengthening India’s solar manufacturing with indigenous air pollution control solutions

Project overview

India’s largest single-location solar PV cell and module manufacturing facility required a comprehensive air pollution control solution to manage hazardous process emissions.

The project marked a shift from dependence on international suppliers to a fully indigenous, turnkey APC solution.

Challenges

Dependence on overseas suppliers for hazardous gas abatement systems
Requirement for a single, reliable partner to deliver end-to-end APC solutions
Need to effectively capture and treat multiple hazardous pollutants generated during solar PV manufacturing
Compliance with stringent environmental and workplace safety norms.

Solution

Delivered a turnkey process exhaust system (PEX) covering engineering, design, supply, erection, and commissioning
Integrated scrubbers, bag filters, activated carbon towers, and stacks into a unified APC system
Designed to capture and treat acidic gases, silane dust, VOCs, alkalis, and heavy metals
Implemented at India’s largest 4 GW solar PV cell and module manufacturing plant

Result

Achieved emissions well within regulatory limits for hazardous gases such as HCl, HF, and Cl₂.
Delivered ~80% VOC removal efficiency
Enabled a safer, cleaner manufacturing environment
Established a milestone for indigenous APC solutions in India’s solar manufacturing sector
