India Set to Become World's Second-Largest Solar Market by 2026

India’s solar sector is entering its most aggressive growth phase yet, with industry estimates indicating that the country is on track to become the world’s second-largest solar market by 2026.

Rapid capacity additions, strong policy backing, and rising demand across industries and households are driving this transformation at an unprecedented pace.

The country has already crossed around 150 GW of installed solar capacity, with nearly 50 GW added in just the last 14 months—marking the fastest expansion in its renewable energy history.

This sharp acceleration reflects a decisive shift from gradual adoption to large-scale deployment. Government-led initiatives such as rooftop solar schemes and rural electrification programs have played a crucial role, while private sector participation has strengthened significantly.

India’s solar journey began gaining momentum in the early 2010s with the launch of the National Solar Mission, which set ambitious targets and created a policy framework for growth. From just a few gigawatts of installed capacity a decade ago, the sector has scaled rapidly due to falling solar tariffs, improved technology, and increased investor confidence. Over time, solar energy has evolved from a supplementary power source into a central pillar of India’s energy transition strategy.

Key Market Data

• Total installed solar capacity: ~150 GW
• Capacity added in last 14 months: ~50 GW
• Annual additions (FY26): ~44–50 GW
• Rooftop solar capacity: ~25.7 GW
• India ranks among the top three solar markets globally
• Solar remains the largest contributor to renewable capacity additions

Growth Drivers

• Strong government policies and financial incentives
• Expansion of rooftop solar across residential and commercial segments
• Rising demand for clean energy from industries
• Production Linked Incentive (PLI) schemes boosting manufacturing
• Declining cost of solar power compared to conventional sources

The expansion has been supported by major domestic players such as Adani Group, Tata Power, and Reliance Industries, alongside renewable-focused firms like ReNew Energy Global, Waaree Energies, and Vikram Solar. These companies are investing heavily in large-scale solar parks, rooftop installations, and domestic manufacturing, contributing to the sector’s rapid growth and helping reduce dependence on imports.

Key Challenges

• Grid and transmission infrastructure constraints
• Delays in project execution due to connectivity issues
• Oversupply risks in solar module manufacturing
• Global trade barriers affecting exports

Future Outlook

India’s solar sector is expected to maintain strong momentum over the next decade, supported by policy continuity and sustained investment. Annual installations are projected to remain in the range of 45–50 GW, ensuring steady capacity expansion.

As global markets such as the United States and parts of Europe experience relatively slower growth, India is expected to play a central role in driving global solar demand. With continued investments in infrastructure, manufacturing, and policy support, the country is positioned to emerge as one of the most influential solar markets worldwide.
