What Happened
- India's solar module manufacturing capacity has surged 13-fold since 2020, reaching approximately 154 gigawatts (GW) by end-2025, while domestic solar installation for the year was a record 38 GW (or ~53 GW in DC terms).
- The mismatch has caused capacity utilisation to plummet from over 70% in 2023 to approximately 40%, creating a structural oversupply — or "glut" — in the solar manufacturing sector.
- Upstream segments of the value chain (cells, wafers, polysilicon) remain underdeveloped; India's strength is concentrated in downstream module assembly.
- Export markets have been disrupted by US tariffs (including 50% reciprocal tariffs under the Trump administration), further squeezing demand for Indian-made modules.
- Cell manufacturing capacity is projected to quadruple to 100 GW over the next two years, threatening a second wave of oversupply.
- A 29 GW inventory buildup was projected by Q3 2025, with module prices under severe downward pressure.

Solar Energy in India: Policy Framework and Targets
India's solar energy programme is among the world's most ambitious. The National Solar Mission (NSM) — one of the eight missions under the National Action Plan on Climate Change (NAPCC) — set the trajectory for large-scale solar deployment. India's current renewable energy target is 500 GW of non-fossil-fuel electricity capacity by 2030, of which solar is expected to contribute approximately 280 GW.
The government has used several policy instruments to incentivise domestic solar manufacturing: Production Linked Incentive (PLI) for solar PV modules, Basic Customs Duty (BCD) on imported cells and modules, and Approved List of Models and Manufacturers (ALMM) to mandate domestic sourcing for government projects.
- India's installed solar capacity: ~110 GW (as of early 2026), up from ~3 GW in 2014
- National Solar Mission launched: 2010, under NAPCC
- BCD on solar modules: 40%; BCD on solar cells: 25% (imposed April 2022)
- PLI for solar PV modules: INR 24,000 crore outlay for 45 GW of high-efficiency module capacity
- ALMM: Mandatory list for procurement in government-funded projects — key demand driver for domestic manufacturers
Connection to this news: The PLI scheme and BCD successfully stimulated massive capacity creation, but demand — both domestic installation and exports — has not kept pace, leading to the structural glut now evident in 40% utilisation rates.
Solar Value Chain: Polysilicon to Module — India's Structural Gap
A complete solar photovoltaic (PV) value chain runs from polysilicon (raw material) through ingots and wafers, to cells, and finally to modules. India has historically been strong only at the module assembly end — the downstream, lower-value-added stage.
Upstream segments (polysilicon, wafers, cells) require massive capital investment, highly specialised technology, and scale economics that currently favour China. This structural gap leaves Indian manufacturers dependent on imported cells and wafers — creating vulnerabilities to supply disruptions and trade actions.
- Polysilicon: China controls ~85% of global production; India has zero domestic production at scale
- Wafers: Similarly China-dominated; requires ultra-high-purity silicon processing
- Solar cells: Convert sunlight to electricity; India's cell capacity growing but lags module capacity
- Modules: Final assembly of cells into panels; India's dominant strength (~154 GW capacity by 2025)
- Cell-to-module manufacturing ratio: India's cell capacity (~25 GW) far below module capacity (~154 GW), creating import dependence for cells
Connection to this news: The glut is partly a story of incomplete value chain development — India rapidly scaled the easiest (module) segment without comparable progress upstream. Sustainable manufacturing competitiveness requires full value chain integration, from polysilicon onwards.
Renewable Energy Manufacturing and Green Industrial Policy
Domestic manufacturing of renewable energy equipment is a dual-priority issue for India: it is simultaneously an industrial policy goal (Make in India, Atmanirbhar Bharat) and a clean energy transition imperative. Solar manufacturing is central to India's climate commitments under the Paris Agreement and its Nationally Determined Contribution (NDC) of achieving 50% of cumulative electric power from non-fossil sources by 2030.
The overcapacity problem is not unique to India — China itself triggered a global solar glut between 2011 and 2013 by massively subsidising domestic manufacturing, which crashed global module prices but wiped out solar industries in the US and Europe. India faces a similar risk of oversupply depressing prices below the viability threshold for domestic manufacturers.
- India's NDC target: 500 GW non-fossil electricity capacity by 2030; 50% total energy from renewables
- Make in India for solar: Part of Atmanirbhar Bharat — reducing import dependence on China for solar equipment
- China's share of global solar manufacturing: ~80% of modules, ~85% of cells, ~85% of polysilicon
- Global solar module prices fell ~80% between 2010 and 2020, and continue declining due to Chinese oversupply
- Anti-dumping investigations: Multiple countries, including India previously, have investigated Chinese solar module dumping
Connection to this news: India's solar glut mirrors the tensions inherent in industrial policy-driven capacity creation — the BCD and PLI successfully created capacity but could not simultaneously create commensurate demand. Policy recalibration may be needed to promote consolidation, value-chain deepening, and export market diversification.
