On July 27, 2026, Praveer Sinha, the CEO of Tata Power, made an announcement: the company would begin exporting solar modules and cells to Europe. This was the ideal moment because the recent EU-India Free Trade Agreement was signed in January 2026. The European Union was interested in reducing its reliance on China for renewable energy materials and had implemented Net-Zero Industry Act which would foster the development of local renewable energy sources. Meanwhile, the U.S. market had become unprofitable for Indian companies after the introduction of anti-dumping duties and other extra tariffs and duties that increased the effective rate of exports to approximate 234%.
Yet beneath the surface of this promising export drive lies a profound structural contradiction: India has built enormous solar module manufacturing capacity, but lacks the cells to fill them - and this bottleneck threatens to derail its European ambitions before they even take off.
The Numbers Tell the Story
India's solar manufacturing landscape is strikingly lopsided. The country has built up nearly 200 GW of solar module manufacturing capacity. But domestic solar cell manufacturing capacity stands at only about 30 GW. The reality on the ground is even more sobering: German research institute EUPD Research estimates that effective operating cell capacity is only around 16 GW to 18 GW. In other words, India has built a massive assembly industry for solar panels, but remains critically dependent on imported cells - overwhelmingly from China - to feed it.
This imbalance has been thrown into sharp relief by a new domestic content requirement that took effect on June 1, 2026, mandating that new solar projects use domestically manufactured solar cells. While intended to boost self-reliance, the policy has instead exposed the fragility of India's solar supply chain.
Factories Idle, Ambitions Stalled
The consequences have been immediate and severe. Module manufacturers lacking their own cell production capacity now face waiting periods of up to six to eight months for domestic cells. The cost of domestically produced panels has nearly doubled compared to those using Chinese cells.
Icon Solar's chairman Shailendra Shukla told Reuters that his company's production capacity would shrink from 3.2 GW to about 1 GW. The All India Solar Module Manufacturers Association reported that nearly one-third of the country's 140 small- and medium-sized solar panel makers - which account for 60% of manufacturing capacity - have halted output entirely, while the rest have reduced operating cycles.
For exporters like Tata Power, which currently has 4.9 GW of integrated cell and module capacity and sees a 2–3 GW opportunity in one European market, the domestic cell shortage means that even if European orders materialize, fulfilling them will be a challenge. "India faces a steep cell supply deficit and closing that gap will likely take three to five years," said Rajan Kalsotra, senior consultant at EUPD Research.
A Long Road Ahead
The Indian government has extended the compliance deadline for some projects to December 2026, but industry insiders remain skeptical. Solex Energy chairman Chetan Shah noted that given the technological complexity and the need for land, raw materials, and supporting infrastructure, cell production cannot be ramped up quickly. Adding to the difficulty, China has curbed exports of solar manufacturing technology, equipment, and technical support.
Meanwhile, even if India resolves its cell shortage, European market entry poses additional hurdles. Chinese manufacturers have spent years building comprehensive certifications and localized service networks across Europe. Indian brands remain virtually unknown in the European market. European buyers are unlikely to abandon a proven, mature supply chain simply for a "non-China" label. And the EU's "de-risking" strategy prioritizes local European manufacturing, not simply swapping one external supplier for another.
Conclusion
India's solar industry finds itself at a crossroads. The export opportunity to Europe is real, driven by geopolitical tailwinds and trade agreements. But ambition alone cannot fill the cell capacity gap. Until India bridges the chasm between its 200 GW of module assembly capacity and its 30 GW of cell production, its European export dreams will remain just that - dreams held hostage by a battery of shortages. As one industry observer put it, India cannot simply rely on policy mandates to achieve industrial upgrading; every bottleneck must be addressed systematically. The cell shortage is not just a supply chain problem - it is the single greatest obstacle to India's emergence as a global solar power.
