Alpex Solar will inaugurate its 2.2 GW TOPCon solar cell plant in Kosi Kotwan, Mathura, on September 16, 2026. The Rs 3,136-crore backward integration project produces advanced G12R cells to feed domestic module plants and comply with MNRE ALMM mandates, curbing import dependence across India's renewable energy sector.
MATHURA/NOIDA — Renewable energy manufacturer Alpex Solar Limited announced that it will formally inaugurate its advanced 2.2-gigawatt (GW) solar cell manufacturing facility in Kosi Kotwan, Mathura district, Uttar Pradesh, on September 16, 2026. The commissioning of the high-tech plant marks the company’s strategic transition from photovoltaic (PV) module assembly to vertically integrated upstream manufacturing.
The launch comes at a critical juncture for India's clean energy sector as federal authorities enforce domestic sourcing requirements across utility, commercial, and residential solar installations, compelling developers to substitute imported photovoltaic components with certified domestic hardware.
Technical Specifications and Backward Integration
The new Alpex Solar solar cell plant deployed state-of-the-art G12R Tunnel Oxide Passivated Contact (TOPCon) manufacturing architecture. TOPCon cell technology delivers operational efficiency ratings exceeding 24.5%, outperforming conventional Mono-PERC (Passivated Emitter and Rear Cell) systems in high-heat operational environments.
According to statutory disclosures, the 2.2 GW capacity was established across industrial units in the Kosi Kotwan Industrial Extension in Mathura within 15 months of initial planning. The total capital outlay of approximately Rs 3,136 crore (Rs 31.36 billion) was financed primarily through internal accruals and public capital raised via market equity expansions.
The enterprise confirmed that rather than commissioning the factory in fragmented phases, the entire 2.2 GW nameplate capacity will become operational simultaneously. Under the company's internal supply framework, between 80% and 85% of the high-efficiency TOPCon cells produced at Kosi Kotwan will feed directly into Alpex’s expanding module fabrication plants in Greater Noida, while the remaining volume will be supplied to external domestic equipment integrators.
Alignment with Federal ALMM Mandates
The commercial activation of the Alpex Solar solar cell plant arrives as the Ministry of New and Renewable Energy (MNRE) accelerates its localization drive through the Approved List of Models and Manufacturers (ALMM).
While ALMM List-I has governed solar modules since 2021, the government introduced ALMM List-II on June 1, 2026, making it compulsory for government-supported projects, green open-access consumers, and grid-connected utility plants to procure only government-approved domestic solar cells. Alpex Solar has formally submitted its application to the MNRE for inclusion under ALMM List-II, with site inspection and technical verification procedures currently underway.
Achieving certified cell production insulates domestic developers from geopolitical shipping bottlenecks, supply tariffs, and foreign exchange volatility, establishing a resilient solar component supply chain in northern India.
Economic Impact on Developers, Investors, and Consumers
The inauguration of the manufacturing facility carries substantial commercial and regional economic implications:
Solar Power Developers: Utility-scale and commercial rooftop engineering, procurement, and construction (EPC) contractors gain immediate access to domestic G12R TOPCon cells, ensuring compliance with federal domestic content requirement (DCR) tenders.
Institutional and Retail Investors: Upstream backward integration into cell fabrication provides higher gross margin visibility. Following fiscal 2026 operating revenues of Rs 2,223 crore, corporate guidance indicates that commercial sales from the Alpex Solar solar cell plant could elevate fiscal 2027 revenues beyond Rs 3,000 crore, supported by projected earnings before interest, taxes, depreciation, and amortization (EBITDA) margins near 25%.
Regional Employment: The factory expands industrial development in Uttar Pradesh's Mathura-Agra manufacturing corridor, generating specialized engineering, automated handling, and technical testing employment across the state.
Clean Energy Consumers: Accelerated local production helps stabilize module pricing, ultimately lowering levelized costs of electricity (LCOE) for commercial solar users and residential rooftop subscribers under national electrification schemes.

Speaking on the strategic readiness of the manufacturing site during an institutional investor briefing, Ashwini Sehgal, Managing Director of Alpex Solar Limited, stated:
"The operationalisation of our 2.2 GW TOPCon cell facility represents a transformative step in our backward integration strategy. By producing high-efficiency G12R cells in-house, we secure complete control over quality and input costs while shielding our operations from global supply chain dislocations. As domestic manufacturing mandates tighten under ALMM regulations, our integrated footprint ensures Alpex Solar remains positioned to deliver reliable clean energy solutions at scale."
Why It Matters
Until recently, India's solar industry remained heavily reliant on overseas manufacturers for advanced photovoltaic cells, even as domestic module assembly capacity expanded rapidly. The commercial operation of a 2.2 GW solar cell plant in Uttar Pradesh significantly reduces import reliance for high-grade N-type cells. Establishing fully domestic cell processing secures industrial resilience, preserves domestic foreign exchange reserves, and strengthens India’s long-term energy transition goals.
