India is currently undertaking one of the fastest renewable energy expansions in the world. By December 2025, the country had installed 258 GW of renewable energy capacity, with solar accounting for over 53% of the total renewable mix. The milestone of deriving 50% of electricity capacity from non-fossil sources was achieved nearly five years ahead of schedule, signalling the rapid pace of India’s energy transition.

The government’s target of 500 GW of non-fossil capacity by 2030 is no longer merely aspirational. According to projections from the International Energy Agency (IEA), India’s renewable capacity could expand 2.5 times between 2025 and 2030, making the country the second-largest renewable growth market globally after China.

However, behind this impressive expansion lies a structural question that is becoming increasingly central to India’s energy strategy: Can India scale solar deployment while simultaneously building supply-chain independence?

In FY2024, India’s solar import bill reached $7 billion, with $3.89 billion sourced from China alone. While India has successfully reduced its dependence on imported finished modules, it has simultaneously become more reliant on Chinese cells, wafers, and polysilicon. In other words, the point of dependence has shifted upstream rather than disappearing altogether.

India’s rapid solar expansion has positioned it as one of the world’s largest renewable markets, but upstream dependence on China for cells, wafers, and polysilicon raises strategic questions. This article examines India’s solar supply chain structure, policy interventions, and the path toward long-term energy manufacturing autonomy.

The Inverted Solar Supply Chain

India’s solar manufacturing ecosystem today resembles what economists describe as an “inverted industrial pyramid.”

At the base of the pyramid—modules—India has built substantial capacity.

• Module manufacturing capacity expanded from 38 GW in March 2024 to 74 GW by March 2025.
• By June 2025 it had exceeded 120 GW, and by early 2026 it reached approximately 144 GW annually.

However, the upstream components of the supply chain remain significantly underdeveloped:

This imbalance means that while India can assemble large volumes of solar modules, the key intermediate components still rely heavily on imports.

Globally, China dominates upstream solar manufacturing:

• 91% of global polysilicon production
• 97% of wafer manufacturing

India’s Ministry of New and Renewable Energy confirmed in Parliament in February 2025 that no commercial polysilicon production currently exists domestically.

The result is a structural dependency that tariffs on finished modules cannot fully address.

When Tariffs Shift Dependence Rather Than Remove It

India’s Approved List of Models and Manufacturers (ALMM) policy and import tariffs have successfully reduced finished module imports from China.

In 2025, module imports from China fell by nearly 40%.

However, the policy had a secondary effect: cell imports from China rose by 47% during the same period.

By the first half of 2025, India accounted for approximately half of China’s global solar cell exports.

This pattern highlights an important lesson in industrial policy: Trade restrictions at one stage of the value chain can shift imports to another stage unless the entire supply chain is developed. India has effectively replaced module dependence with component dependence.

The Cost Gap: Structural Economics of Solar Manufacturing

Another challenge lies in the price competitiveness of domestic manufacturing. As of December 2025:

• Chinese TOPCon modules shipped at $0.088 per watt
• Indian Domestic Content Requirement (DCR) modules cost $0.28–$0.29 per watt
• Indian modules using imported cells cost roughly $0.15 per watt

These cost differences reflect structural advantages China has accumulated over decades.

China’s solar industry benefits from:

• lower industrial electricity prices
• economies of scale
• vertically integrated manufacturing
• significant state support

Estimates suggest Chinese state backing for solar manufacturing has exceeded $130 billion since 2023 alone.

By comparison, India’s Production Linked Incentive (PLI) scheme has attracted ₹48,120 crore in private investment a meaningful but smaller industrial base.

The consequence is that domestic solar manufacturing currently operates at a cost premium, which may ultimately influence electricity tariffs if domestic supply chains remain expensive.

Policy Instruments: Achievements and Limitations

India has implemented several policy tools to build solar manufacturing capacity.

1. Production Linked Incentive (PLI): The PLI scheme has played a key role in attracting investment into module manufacturing.However, the scheme rewards post-production sales over five years, while upstream manufacturing facilities such as polysilicon plants require over $1 billion in upfront capital investment. This mismatch means the incentive structure may favor downstream assembly rather than upstream manufacturing.

2. ALMM Framework: The ALMM framework has been one of the most operationally effective instruments.

• List I accelerated module manufacturing.
• List II, requiring domestically manufactured cells from June 2026, may arrive before sufficient cell capacity exists.

India currently installs 40–50 GW of solar annually, while domestic cell capacity remains 29 GW.

Future proposals to extend ALMM to wafers and ingots could face even larger capacity gaps.

3. Trade Measures and WTO Dynamics: India imposed anti-dumping duties of 23–30% on Chinese solar imports in September 2025. China responded with a WTO consultation request in December 2025, arguing that India’s PLI scheme functions as an import-substitution subsidy.While enforcement uncertainty exists due to the WTO Appellate Body’s current paralysis, such disputes illustrate the growing complexity of industrial policy in globally integrated sectors.

Solar Manufacturing and India’s Trade Balance

India’s trade relationship with China illustrates the scale of economic interdependence.

India’s trade deficit with China reached:

• $99.2 billion in FY2024–25
• $116.12 billion in calendar year 2025

While solar deployment was intended to reduce fossil fuel import dependence, it has simultaneously introduced a new form of industrial dependency through equipment and component imports.

The 2030 Outlook: Deployment Success, Manufacturing Uncertainty

India’s solar deployment trajectory remains strong. BloombergNEF forecasts over 50 GW of annual solar installations by 2026, making India the second-largest solar market globally.

However, analysts project that while India could achieve module and cell self-sufficiency by 2027–2028, it may remain 70–90% dependent on imported wafers and polysilicon through the end of the decade.

In other words, India’s solar expansion is assured.
Its manufacturing autonomy remains a work in progress.

Constructive Policy Pathways

India’s solar manufacturing strategy has already delivered meaningful progress. The next stage requires targeted policy refinement rather than wholesale redesign.

1. Incentivise Upstream Manufacturing: Future incentives should focus more strongly on capital-intensive upstream components, particularly polysilicon and wafer manufacturing.Dedicated long-term financing instruments may be more effective than sales-linked incentives for such facilities.

2. Expand Strategic Technology Partnerships: Partnerships with countries such as the United States, Japan, South Korea, and the European Union could help diversify equipment and technology sources.This would reduce reliance on a single supplier ecosystem.

3. Strengthen Domestic Equipment Manufacturing: India’s solar strategy should increasingly focus on manufacturing machinery and production equipment, not just solar components themselves.This represents the next frontier of industrial capability.

4. Build Critical Mineral Supply Chains: Solar manufacturing requires access to minerals such as silicon, silver, and rare earth elements.Strengthening domestic refining and mineral processing capacity could reduce long-term supply risks.

From Deployment Leadership to Manufacturing Leadership

India’s solar policy has achieved something remarkable. Within a decade, it has built one of the world’s largest solar deployment ecosystems and a 144 GW module manufacturing industry.

However, true strategic autonomy requires deeper supply chain integration.

Assembly-led expansion can create industrial scale quickly, but upstream capability determines whether that scale becomes structural competitive advantage.

India’s solar sector now stands at the transition point between deployment leadership and manufacturing leadership.

How successfully India navigates this transition will determine whether the country becomes not only one of the world’s largest solar markets—but also one of its most important solar manufacturing powers.
