Vikram Solar's Tamil Nadu Plant to Begin TOPCon Production in December 2026
Vikram Solar is scheduled to begin TOPCon cell production at its Tamil Nadu manufacturing plant in December 2026, according to reports published on 26 October 2026 by PV Tech and SolarQuarter. SolarQuarter reported the plant's capacity at 9 GW; PV Tech's headline did not state a capacity figure. No project value was reported by either outlet.

Capacity Figure: What the Two Outlets Reported
The two outlets agree on the December 2026 production start date and the Tamil Nadu location. On capacity, however, only SolarQuarter specified a figure — 9 GW. PV Tech's headline made no reference to a capacity number. Readers should note that the 9 GW figure is corroborated by one outlet only. No financial value, sub-contractor or detailed breakdown of scope was available from the published headlines.
TOPCon Technology and India's Solar Manufacturing Push
TOPCon (Tunnel Oxide Passivated Contact) is a higher-efficiency cell architecture that has attracted increasing investment from module and cell manufacturers globally. A manufacturing facility of the scale reported by SolarQuarter would represent a significant addition to India's domestic cell production base, though no comparative ranking is supported by the available evidence. Tamil Nadu has emerged as a hub for solar manufacturing investment in recent years, complementing the large pipeline of solar generation projects being developed across India.
India's Solar Project Pipeline: Where Activity Is Concentrated
The commissioning of domestic cell manufacturing capacity comes as India's solar project pipeline remains substantial. Projects India tracks 1,314 live projects in the Solar Based Power sub-sector, with 23 added in the last 90 days alone.
By state, the highest concentrations of tracked solar projects are in Maharashtra (189 projects), Karnataka (188), Telangana (139), Andhra Pradesh (93), Gujarat (86) and Rajasthan (83). Tamil Nadu, where the Vikram Solar plant is located, is an active market both for generation projects and, now, for cell manufacturing.
The stage breakdown of tracked solar projects illustrates where activity is headed. Of the 1,314 projects tracked:
- 643 are Under Approvals — the largest single cohort, representing future demand for equipment and construction services
- 221 have Construction Started — the most immediately active tier for suppliers and contractors
- 194 are in Planning
- 129 are Completed
- 47 are on Hold
- 25 are at Early / Announced stage
The 643 projects under approvals, combined with the 194 in planning, indicate a large volume of procurement activity that is yet to materialise — relevant context for cell and module suppliers assessing forward demand. Recent projects moving into construction include NTPC Limited's solar project at Bhanipura, Rajasthan; NTPC Renewable Energy Limited's Rs 1,338 crore project at Sitapur, Uttar Pradesh; and Adani Green Energy Limited's Rs 469 crore project at Khavda, Kutch, Gujarat. See the Power Projects sector overview for further context across the broader sector.
Recent Tamil Nadu Solar Policy Context
Tamil Nadu's solar ambitions extend beyond manufacturing. TNPDCL has been approved to procure 600 MW of solar power with storage at Rs 3.12 per unit, signalling continued state-level commitment to expanding solar generation capacity — a backdrop that supports investment in local manufacturing infrastructure.
What this means for suppliers and contractors
The reported commencement of TOPCon cell production at Vikram Solar's Tamil Nadu plant is relevant to several categories of supplier. Equipment providers serving cell manufacturing — including process equipment, automation systems and ancillary infrastructure — would find Tamil Nadu an active geography. Downstream, the large pipeline of solar generation projects across Maharashtra, Karnataka, Telangana and other states creates sustained demand for modules, mounting structures, inverters, cables and civil contractors.
The 643 solar projects currently under approvals nationally represent the clearest leading indicator of near-term procurement. Suppliers tracking these projects as they move from approvals into construction will be best placed to engage early. Projects India tracks all live and pipeline solar projects; the full list is available at the tracked projects page. There are currently no open India tenders in the Power Projects sector recorded in our database.
Frequently asked questions
When will Vikram Solar start TOPCon cell production at its Tamil Nadu plant?
Vikram Solar is reported to begin TOPCon cell production at its Tamil Nadu plant in December 2026, according to reports published by PV Tech and SolarQuarter on 26 October 2026. No earlier or revised date has been reported.
What is the capacity of Vikram Solar's Tamil Nadu TOPCon plant?
SolarQuarter reported the plant's capacity at 9 GW. PV Tech's report did not state a capacity figure. The 9 GW figure is therefore corroborated by one outlet only and should be treated accordingly.
How many solar projects are currently tracked in India?
Projects India tracks 1,314 live projects in the Solar Based Power sub-sector across India, with 23 added in the last 90 days. Maharashtra and Karnataka have the highest concentrations, with 189 and 188 projects respectively.
