Alpex Solar Limited has inaugurated a 2.2 GW solar cell manufacturing facility at Kosi Kotwan in Mathura, Uttar Pradesh, marking a major expansion of the company’s manufacturing capabilities and adding significant domestic solar-cell production capacity.
The facility is designed to manufacture G12R TOPCon solar cells, a high-efficiency technology increasingly being adopted across the global photovoltaic industry.
Alpex Solar disclosed the development through a regulatory filing with the National Stock Exchange of India (NSE) under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.
2.2 GW Solar Cell Manufacturing Capacity
The newly inaugurated facility has an annual manufacturing capacity of 2.2 GW.
The plant will manufacture G12R TOPCon solar cells, positioning the facility within India’s rapidly expanding high-efficiency solar manufacturing ecosystem.
TOPCon technology is gaining importance because it offers higher efficiency compared with several conventional crystalline-silicon cell technologies. Increasing domestic production of such cells can support India’s efforts to build a more integrated solar manufacturing supply chain.

Why the 2.2 GW Capacity Is Important
A 2.2 GW annual solar-cell manufacturing facility represents a significant addition to India’s domestic photovoltaic manufacturing capacity.
Solar cells are a critical stage in the solar-panel value chain. Expanding domestic cell manufacturing can help reduce reliance on imported cells and strengthen the supply chain between raw materials, wafers, cells and finished solar modules.
The facility therefore has significance beyond Alpex Solar itself, as it contributes to the broader development of India’s domestic renewable-energy manufacturing base.
Focus on G12R TOPCon Technology
The new plant is focused on G12R TOPCon solar cells, reflecting the industry’s shift towards higher-efficiency photovoltaic technologies.
TOPCon, or Tunnel Oxide Passivated Contact technology, is being adopted by manufacturers seeking to improve solar-cell performance and module efficiency.
The use of G12R-format cells also reflects the industry’s continuing move toward larger wafer and cell formats aimed at improving module power output and manufacturing efficiency.
Potential Employment Generation
The company has not disclosed a specific employment figure for the new 2.2 GW facility in the regulatory announcement provided.
However, a manufacturing plant of this scale can support employment across several areas, including:
- Solar-cell production
- Electrical and mechanical engineering
- Equipment operation
- Quality control
- Research and technical functions
- Plant maintenance
- Supply-chain management
- Logistics and warehousing
- Administration and support services
The wider economic impact can extend to contractors, equipment suppliers, logistics companies, industrial maintenance firms and other ancillary businesses.
For Mathura and the surrounding region, the facility could therefore contribute to the development of a larger renewable-energy manufacturing workforce.
Boost to Uttar Pradesh’s Solar Manufacturing Ecosystem
The project strengthens Uttar Pradesh’s position as an emerging destination for renewable-energy manufacturing.
The state’s large domestic market, industrial infrastructure and connectivity with major consumption centres provide opportunities for solar equipment manufacturers to establish and expand production.
The Alpex Solar facility adds solar-cell manufacturing to this ecosystem, helping move the value chain beyond module assembly towards upstream manufacturing.
A stronger local cell-manufacturing base could also encourage investments in related areas such as:
- Solar modules
- Wafers
- Solar glass
- Encapsulants
- Backsheets
- Junction boxes
- Solar inverters
- Manufacturing equipment
- Recycling and waste management
Strategic Importance for India’s Solar Industry
India has been expanding domestic renewable-energy manufacturing capacity as solar installations continue to grow.
A major challenge for the sector has been developing a complete domestic value chain covering different stages of solar-panel manufacturing.
The addition of new cell capacity can help address this gap.
Alpex Solar’s 2.2 GW facility can potentially supply cells for domestic module manufacturing, supporting greater integration within India’s photovoltaic supply chain.
Economic Opportunities Around Mathura
The establishment of a large solar manufacturing facility can generate economic activity beyond the plant itself.
Local businesses may benefit from demand for:
Logistics: Transportation of equipment, raw materials and finished cells.
Industrial services: Equipment maintenance, electrical services and plant engineering.
Warehousing: Storage and movement of manufacturing inputs and finished products.
Contract services: Security, housekeeping, facility management and other operational services.
Ancillary manufacturing: Opportunities for suppliers of components and industrial consumables.
As the renewable-energy ecosystem develops, these supporting activities can contribute to additional indirect employment in the region.
Regulatory Disclosure
Alpex Solar disclosed the facility’s inauguration through a filing with the National Stock Exchange of India under Regulation 30 of the SEBI Listing Obligations and Disclosure Requirements Regulations, 2015.
The filing dated September 4, 2026, also included the invitation related to the inauguration event.
The regulatory communication was signed by Sakshi Tomar, Company Secretary and Compliance Officer of Alpex Solar Limited.
Investment Figure Yet to Be Disclosed in This Announcement
While the manufacturing capacity has been disclosed at 2.2 GW, the regulatory announcement supplied for this report does not specify the total investment made in the facility.
Similarly, a project-specific employment figure has not been provided in the announcement.
These figures should therefore be added only when confirmed through an official company filing, annual report, investor presentation or other authoritative disclosure.
