India’s solar sector entered a transformative phase in 2025. As the nation chases its ambitious target of 500 GW of non-fossil fuel energy by 2030, the solar supply chain has become a core pillar of this journey. With manufacturing capacity booming, government support rising and private investments scaling up, India is not just fulfilling domestic demand but emerging as a global solar manufacturing hub. Yet, challenges like upstream import dependence, cost competitiveness and technological bottlenecks continue to test the resilience of India’s solar supply chain.
Let’s explore the opportunities and challenges that will define India's solar supply chain in 2025 and what this means for the future of clean energy.
India’s solar industry in 2025 is witnessing a remarkable transformation, marked by a surge in domestic manufacturing, rising exports, and strong policy support. The country is rapidly building a robust solar supply chain, enabling local manufacturers to scale operations and attract global attention. This shift is not only strengthening India’s energy sector but also creating new economic opportunities across states and industries.
What sets this phase apart is the convergence of technological progress, government incentives, and strategic global positioning. From doubling module manufacturing capacity to emerging as an export hub through the “China Plus One” strategy, India is capitalising on multiple fronts. These opportunities are laying the groundwork for long-term energy independence and making India a critical player in the international solar supply ecosystem.
India’s solar module manufacturing capacity skyrocketed from 38 GW in March 2024 to 74 GW in March 2025, nearly doubling in a single year. PV cell manufacturing also tripled from 9 GW to 25 GW. This growth is not random; it’s powered by strong policies like the Production Linked Incentive (PLI) Scheme, which has already attracted over INR 41,000 crore in investments and created thousands of jobs.
Key Insight: The solar supply chain is benefiting from clear government direction, long-term vision and aggressive localisation policies.
India is now becoming a serious contender to China in the solar supply ecosystem. In 2024, India exported 5.8 GW of PV modules, triple the figure from the previous year.
Why It Matters: India's cost advantage in labour, plus policy-driven manufacturing, is making it a reliable alternative to China in global solar supply chains.
Leading manufacturers are investing in high-efficiency PV modules using next-gen technologies like:
These technologies are pushing panel efficiencies to 23.1% and beyond, ensuring better ROI for both domestic and international buyers.
States like Gujarat, Rajasthan, Telangana and Tamil Nadu are rapidly becoming solar manufacturing ecosystems. With integrated production setups, ranging from ingots and wafers to modules, these states are leveraging port connectivity, power availability and policy incentives.
Example:
Key initiatives shaping India’s solar supply chain in 2025 include:
These policies are fostering a robust Atmanirbhar Bharat ecosystem in solar energy manufacturing.
While India’s solar sector has made impressive strides in recent years, several critical challenges continue to hinder its full potential. Beneath the surface of booming manufacturing and export growth lie structural gaps that need urgent attention. These include limited upstream capabilities, overreliance on imports for key components, and high production costs driven by energy intensity and technological limitations.
To establish a truly resilient and self-sustaining solar supply chain, India must address these bottlenecks head-on. From building a stronger foundation for ingot and wafer production to ensuring access to advanced manufacturing technologies, overcoming these challenges is essential for maintaining momentum. Tackling them will not only improve India’s competitiveness on the global stage but also enhance its energy security and long-term industrial strength.
Even though India is making strides in module and cell manufacturing, it still depends on imports for upstream materials:
In FY 2024, $3.89 billion out of $7 billion in solar imports came from China. This dependence creates:
Solution: Investing in local upstream production and incentivising indigenous ingot and wafer manufacturing is crucial.
While domestic module and cell capacity are booming, ingot and wafer production are still nascent. Only one 2 GW ingot-wafer plant began operation in FY25.
Why the delay?
India's coal-heavy power grid makes upstream production (like polysilicon refining) costlier and more emissions-intensive compared to China.
A fully localised Indian supply chain today is around 15% more carbon-intensive than China's.
Some manufacturers like First Solar are switching to solar and wind to power their production lines, offering a roadmap to green manufacturing in India.
India still lags in:
This limits India’s ability to compete on cost and efficiency, especially with Chinese Tier 1 manufacturers.
Some well-intended schemes like:
…are facing delays, limited uptake, or procedural bottlenecks, weakening their intended impact.
India’s solar supply chain in 2025 is marked by:
However, to transition from a booming market to a dominant global player, India must:
With India already ranked among the Top 3 global solar markets, the right moves today can make it the solar manufacturing capital of the world by the end of the decade.
