Indian solar manufacturer Vikram Solar has unveiled intentions to situate a 9GW wafer and ingot production line within its newly opened 6GW solar PV module factory in Gangaikondan, Chennai, located in the southern state of Tamil Nadu. The company stated that its board has given the green light to these proposals, which are designed to consolidate the entire solar manufacturing process, spanning from ingot to module, within a single facility.
Vikram Solar indicated that this initiative seeks to lessen reliance on imports, bolster domestic PV supply chains, and advance India’s efforts toward greater energy independence as part of the Atmanirbhar Bharat program. Earlier this week, the firm inaugurated the 6GW cell manufacturing unit, situated on a greenfield campus covering roughly 600,000 square feet, which is expected to provide jobs for more than 800 individuals.
In the previous month, the company activated its module production site, which is set to manufacture Vikram’s Hypersol n-type tunnel oxide passivated contact (TOPCon) G12R panels, delivering power ratings between 615W and 640W and achieving module efficiencies reaching up to 23.69%. Vikram shifted its entire module lineup to the G12R format in January 2026, highlighting factors such as performance, dependability, and financial viability.
This inauguration comes on the heels of the recent opening of Vikram Solar’s 5GW Vallam production facility in Tamil Nadu. In April, the company achieved a milestone of surpassing 10GW in cumulative global solar module shipments, having doubled its deployment figures from 5GW to 10GW within a two-year span, with approximately 1.5GW of that total going to overseas markets.
Based in Kolkata, the company has set targets to establish 9GW of solar cell manufacturing capacity by fiscal year 2027, increase that by an additional 3GW by fiscal year 2028, and introduce 12GW of wafer and ingot production capacity by fiscal year 2029-30. In June, reports emerged that Vikram Solar was considering an investment of INR270 billion (US$2.8 billion) in a fully integrated solar manufacturing hub in West Bengal, encompassing ingot, wafer, cell, and module production, though the company has not officially verified these reports.
Separately, Indian solar products firm Websol Energy System has relocated the proposed site for its 4GW greenfield solar cell and module manufacturing plant from Andhra Pradesh to West Bengal. The company noted that it is currently awaiting necessary approvals to acquire land adjacent to its current facility in Falta, West Bengal. Websol confirmed that this change in location will not alter the previously disclosed schedule for the INR30 billion (US$313.8 million) expansion project.
The project is slated for development in two stages, with each stage including 2GW of solar cell capacity and 2GW of solar module capacity. The initial phase is expected to be operational by June 2027, while the second phase is projected to commence operations in June 2028. The 4GW facility was originally intended for the Multi Product Special Economic Zone (MPSEZ) in Naidupeta, Andhra Pradesh, and had received approval from the Andhra Pradesh state government in January.
By shifting to West Bengal, the new capacity would be situated alongside Websol’s existing operations in Falta, potentially enabling the company to leverage its current manufacturing infrastructure and local resources. Kolkata-headquartered Websol is also advancing efforts to convert one of its existing monocrystalline passivated emitter rear contact (PERC) cell production lines to TOPCon technology.
Last week, the manufacturer initiated a brownfield upgrade of its current 600MW PERC line to TOPCon, which is expected to boost its TOPCon cell capacity to 750MW and raise total cell manufacturing capacity to 1.35GW, up from 1.2GW. This upgrade is slated for completion by March 2027, after which TOPCon is projected to represent roughly 55% of Websol’s overall cell manufacturing capacity.
During the first quarter of its fiscal year 2027, spanning April through June 2026, cell output more than doubled to 259MW, compared to 126MW in the same period a year prior. Websol runs a production facility at the Falta Special Economic Zone in West Bengal, with an 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 Energies’ (MNRE) Approved List of Models and Manufacturers (ALMM) List-II, bringing its total listed cell capacity to 1.2GW.
