Indian PV manufacturer Vikram Solar has announced plans to house a 9GW wafer and ingot plant within its recently inaugurated 6GW solar PV module manufacturing plant at Gangaikondan, Chennai, in the southern state of Tamil Nadu.
According to the firm, the plans have been approved by the board and aim to bring the entire solar value chain, from ingot to module, under a single roof.

The move is aimed at reducing import dependence, strengthening domestic PV supply chains and supporting India’s drive towards greater energy self-sufficiency under the Atmanirbhar Bharat initiative, the manufacturer said.
Earlier this week, Vikram Solar inaugurated the 6GW cell plant. Set within a larger greenfield campus of nearly 600,000 square feet, the manufacturing plant will employ over 800 workers.
Last month, the company commissioned the module manufacturing facility. The plant will manufacture Vikram’s Hypersol n-type tunnel oxide passivated contact (TOPCon) G12R modules, offering power outputs of 615-640W and module efficiencies of up to 23.69%.
Vikram transitioned its module portfolio to the G12R format in January 2026, citing “performance, reliability and bankability.”
The inauguration follows the recent launch of Vikram Solar’s 5GW Vallam manufacturing facility in Tamil Nadu.
In April, Vikram Solar surpassed 10GW of cumulative global solar module deployments, doubling deployments from 5GW to 10GW in two years. Of the total, around 1.5GW was exported to international markets.
Headquartered in Kolkata, the company plans to install 9GW of solar cell manufacturing capacity by FY2027, expanding that by a further 3GW by FY2028 and add 12GW of wafer and ingot manufacturing capacity by FY2029-30.
In June, Vikram Solar was reportedly planning to invest INR270 billion (US$2.8 billion) in a vertically integrated solar manufacturing hub in West Bengal, covering ingot, wafer, cell and module production, although the company has yet to confirm the report.
Websol shifts planned 4GW solar cell and module factory from Andhra Pradesh to West Bengal
In other news, Indian solar products manufacturer Websol Energy System has shifted the planned location of its proposed 4GW greenfield solar cell and module manufacturing facility from Andhra Pradesh to West Bengal.
The company said that it is currently awaiting the requisite approvals to secure land near its existing manufacturing facility in Falta, West Bengal.
The relocation will not affect the previously announced timeline for the INR 30 billion (US$ 313.8 million) expansion, Websol said.
The project will be developed in two phases, with each phase comprising 2GW of solar cell and 2GW of solar module manufacturing capacity.
The first phase is targeted for commissioning in June 2027, with the second phase scheduled to come online in June 2028.
The 4GW facility was initially planned for the Multi Product Special Economic Zone (MPSEZ) in Naidupeta, Andhra Pradesh. The proposal received approval from the Andhra Pradesh state government in January.
The move to West Bengal would place the new capacity alongside Websol’s existing operations at Falta, potentially allowing the company to build on its established manufacturing base and local infrastructure.
Kolkata-based Websol is also progressing with the upgrade of one of its existing monocrystalline passivated emitter rear contact (PERC) cell production lines to TOPCon technology.
Last week, the manufacturer began a brownfield upgrade of its existing 600MW PERC line to TOPCon technology, which is set to increase its TOPCon cell capacity to 750MW and total cell manufacturing capacity to 1.35GW, from 1.2GW.
The upgrade is scheduled for completion by March 2027, after which TOPCon would account for around 55% of Websol’s total cell manufacturing capacity.
For the first quarter of its fiscal year 2027 – covering April through June 2026 – cell production more than doubled to 259MW, from 126MW a year earlier.
Websol operates a manufacturing facility at the Falta Special Economic Zone in West Bengal, with a current annual nameplate solar cell capacity of 1.2GW and an annual nameplate module capacity of 550MW.
In April 2026, Websol added 600MW of monocrystalline PERC P-type bifacial cell capacity at its West Bengal plant to the Ministry of New and Renewable Energy’s (MNRE) Approved List of Models and Manufacturers (ALMM) List-II, taking its total listed cell capacity to 1.2GW.
