India solar manufacturing hits $16 bn investment surge, can absorb US trade blow
Synopsis
India's solar manufacturing has gone from a $85 million sector in 2018 to a $16 billion investment magnet in 18 months, with module capacity soaring to 242.7 GW. Even as US anti-dumping probes threaten a $1.2 billion export stream, the Rhodium Group says India's own booming domestic market is the sector's best insurance policy.
Key Takeaways
India attracted $16 billion in solar manufacturing investment over 18 months — $12 billion in 2025 and $4 billion in H1 2026, up from just $85 million in 2018.
Solar module manufacturing capacity has expanded from 2.5 GW in 2014 to 242.7 GW , per the Rhodium Group report.
India now holds 40.5 GW of cell capacity and 2.5 GW of wafer capacity, with 40 GW and 24 GW more respectively in the pipeline.
Indian solar exports to the US were worth $1.2 billion in 2025, equal to about 13% of total module and cell production value.
The US International Trade Commission has yet to rule on material injury — a finding that would trigger anti-dumping and countervailing duties.
The ALMM policy mandating domestic sourcing has been a key driver; an extension to wafers is reportedly under consideration.
India's solar manufacturing sector has emerged as one of the country's most compelling industrial success stories, with $16 billion invested over just 18 months and a domestic market large enough to absorb additional supply even as fresh US trade measures threaten export revenues, according to a new report released on 29 September 2026.
Scale of the Investment Surge
Investment in Indian solar manufacturing climbed from approximately $85 million in 2018 to $12 billion in calendar year 2025, with a further $4 billion committed in the first half of 2026, according to the Clean Investment Monitor report published by the Rhodium Group, a US-based market research and analytics firm specialising in renewable energy.
Module manufacturing capacity has expanded from roughly 2.5 GW in 2014 to 242.7 GW today — a near hundredfold increase. India had no domestic cell capacity in 2014; it now holds 40.5 GW of cell capacity and 2.5 GW of wafer capacity, the report noted.
Closing the Capacity Gap
The Rhodium Group report flagged a visible mismatch between module manufacturing capacity and the lower cell and wafer capacities. However, it projected this gap would narrow significantly, with an additional 40 GW of cell capacity and 24 GW of wafer capacity expected to come online in the near term.
The rapid build-up has been anchored by a government policy framework, notably the Approved List of Models and Manufacturers (ALMM), which mandates the use of domestically produced modules and cells across solar projects. The policy now covers nearly all solar installations in India, with limited exemptions for certain net-metering and open-access projects that have been granted a commissioning window until 31 December. Efforts are reportedly underway to extend the ALMM to wafers as well.
US Trade Measures: The Export Headwind
The United States remains an important export destination for several Indian solar manufacturers. India's exports of modules and cells to the US were valued at approximately $1.2 billion in 2025, representing around 13% of the total value of modules and cells produced domestically.
The US International Trade Commission is yet to determine whether those imports have caused material injury to American domestic industry — a finding that would trigger anti-dumping and countervailing duties. Should such duties be imposed, they would represent a significant headwind for Indian exporters currently reliant on the US market.
Why Domestic Demand Provides a Buffer
The report argued that India's large and rapidly expanding domestic solar market is capable of absorbing the additional supply that would otherwise flow to the US, even if margins come under pressure. This comes amid India's aggressive renewable energy expansion targets, which continue to drive strong local demand for solar equipment.
Notably, the trajectory from $85 million to $16 billion in cumulative investment over roughly eight years underscores a structural transformation rather than a cyclical uptick — a shift that analysts say is difficult to reverse even under external trade pressure. With further capacity additions in the pipeline and policy support firmly in place, India's solar manufacturing ecosystem appears positioned to weather the uncertainty around US trade policy, though the margin impact on exporters bears watching.
Point of View
But the 13% US export exposure is a real vulnerability that should not be glossed over in the celebratory tone. The domestic absorption argument is credible given India's own renewable capacity targets, yet margin compression — which the Rhodium Group itself concedes — could chill further investment if returns thin out. More importantly, the glaring mismatch between 242.7 GW of module capacity and just 40.5 GW of cells points to a supply chain still heavily dependent on imported inputs upstream. Until wafer and polysilicon capacity catches up, 'Made in India solar' remains partially a re-assembly story, and that is precisely the kind of detail US trade investigators are likely to scrutinise.

Frequently Asked Questions
How much has India invested in solar manufacturing recently?
India attracted approximately $16 billion in solar manufacturing investment over 18 months — $12 billion in calendar 2025 and a further $4 billion in the first half of 2026, according to the Rhodium Group's Clean Investment Monitor report. This compares with just $85 million invested in 2018.
What is India's current solar module manufacturing capacity?
India's solar module manufacturing capacity stands at 242.7 GW as of the latest data, up from about 2.5 GW in 2014. The country also holds 40.5 GW of cell capacity and 2.5 GW of wafer capacity, with substantial additions expected in both categories.
How could US trade measures affect Indian solar exporters?
The US International Trade Commission is investigating whether Indian solar imports have caused material injury to domestic US manufacturers — a ruling that could result in anti-dumping and countervailing duties. Indian exports of modules and cells to the US were worth $1.2 billion in 2025, representing about 13% of India's total module and cell production value.
Can India's domestic market absorb supply if US exports are blocked?
The Rhodium Group report says yes, arguing that India's large and growing domestic solar market can absorb the additional supply that would otherwise go to the US, though it acknowledges that manufacturer margins may be squeezed in the process.
What is the ALMM policy and why does it matter?
The Approved List of Models and Manufacturers (ALMM) is a government policy that mandates the use of domestically produced solar modules and cells in nearly all Indian solar projects. It has been a primary driver of the investment surge and capacity build-up, and is reportedly being extended to cover wafers as well.
