India's Largest Solar Cell Line Goes Live - Localisation Moves Down the Stack, Not Yet to the Wafer
- On 21 September 2026 Premier Energies commissioned a 7 GW solar cell facility in Andhra Pradesh, described as India's largest, at a project cost of about Rs 3,293 crore.
- The commissioning lifts the company's total solar cell capacity to about 10.6 GW.
- Cells, not modules, are the import-dependent higher-value layer India has largely bought from China; a domestic 7 GW cell line moves localisation down the stack.
- Wafers and polysilicon upstream remain overwhelmingly imported - the test is whether Indian cells are fed by domestic wafers or just shift the import point upstream.

The development
On 21 September 2026, Premier Energies commissioned a 7 GW solar photovoltaic cell manufacturing facility in Andhra Pradesh at a cost of roughly Rs 3,293 crore, described by industry press as India''s largest single solar cell facility. The commissioning lifts the company''s total cell capacity to about 10.6 GW and sits alongside its module capacity. Reporting frames the plant as part of India''s push to localise the cell layer of the solar supply chain.
Why it matters
India has rapidly built solar module assembly, but cells - the higher-value, more technology-intensive layer - have been largely imported, chiefly from China. A domestic 7 GW cell line materially expands India''s own cell base and reduces one layer of import dependence in the solar stack, moving localisation past final assembly.
The dependency and systems frame
Module assembly was always the easy layer; cells are harder, and wafers and polysilicon upstream are harder still and remain overwhelmingly imported. A large domestic cell facility narrows the cell gap but does not close the wafer-and-polysilicon dependency above it, nor the equipment and specialty materials imported to run the cell line itself. The systems test is whether Indian cell capacity is fed by domestic wafers, or simply moves the import point one step upstream.
What to watch
- Utilisation and yield of the new cell capacity versus its 7 GW nameplate.
- Whether domestic wafer, ingot and polysilicon capacity develops to feed Indian cell lines rather than importing wafers.
- ALMM and domestic-content demand pull, plus any export orders for Indian-made cells.
