India is on track to become the world’s second-largest solar market by 2026, adding over 50 GW of new capacity. Yet challenges in manufacturing viability, financing rooftop systems, and policy clarity cast uncertainty on the sector’s long-term sustainability. The boom is undeniable, but its durability remains in question.
Key Highlights
-
Record Growth: India is set to overtake the US as the world’s second-largest solar market in 2026, with projections of over 50 GW of new capacity additions, according to BloombergNEF.
-
Rooftop Surge: Distributed and rooftop solar are gaining traction, with 8 GW expected from rooftop systems alone in fiscal 2026 , a sharp rise from previous years.
-
Budget Expectations: Ahead of the Union Budget 2026, industry leaders are urging the government to focus on manufacturing viability and large-scale deployment using public assets like Indian Railways.
-
Global Context: India’s rise comes even as global solar installations decline for the first time, largely due to a slowdown in China.
-
Uncertainty Ahead: Despite the boom, concerns remain about financing, policy clarity, and supply chain resilience, raising questions about whether India can sustain this pace.
The Current Boom
India’s solar sector is in full throttle mode, adding capacity at record speed. In 2025 alone, the country added 44.5 GW of renewable energy, with solar accounting for the lion’s share. This momentum is reshaping India’s energy landscape, reducing dependence on fossil fuels, and positioning the nation as a global leader in renewables.
The Challenges
Yet, beneath the optimism lies uncertainty. Manufacturing viability remains a pressing issue, with domestic producers struggling to compete against cheaper imports. Financing rooftop solar projects is another hurdle, as banks remain cautious about lending to small-scale distributed systems. Policy clarity is also critical — without consistent incentives and regulatory frameworks, the sector risks slowing down.
Why It Matters
India’s solar boom is more than an energy story; it’s about economic resilience, climate commitments, and global leadership. If sustained, it could transform India into a renewable powerhouse. But if challenges are left unaddressed, the boom may falter, leaving the country vulnerable to energy shortfalls and missed climate targets.
