India’s solar journey has been nothing short of transformative. From humble beginnings, the nation has emerged as a global leader in solar energy, reflecting a commitment to sustainable development, energy security, and climate action. Solar power is no longer a niche sector. It has now become a critical driver of India’s clean energy transition and economic growth.
Current Capacity and Growth Trajectory
As of August 2025, India’s installed solar capacity has crossed 123.13 GW, marking a significant milestone in its renewable energy expansion. Projections indicate a CAGR of nearly 23% between 2023 and 2027, aiming for 185 GW by 2027 and 365 GW by 2032. These ambitious targets reflect both the scale of India’s ambitions and its execution capabilities, with investments from public, private, and international stakeholders accelerating growth.
Regional Solar Leaders
Certain states have emerged as solar powerhouses due to favourable sunlight conditions, infrastructure, and policy support. Rajasthan, Gujarat, Maharashtra, Tamil Nadu, and Madhya Pradesh lead the way, hosting a mix of utility-scale solar parks and growing rooftop installations. These regions not only supply clean energy to local grids but also set benchmarks for replication across the country.
Policy and Market Momentum
Government initiatives such as Production-Linked Incentive (PLI) schemes for solar module manufacturing and programs like PM Surya Ghar Muft Bijli Yojana have catalysed growth. Under the Production Linked Incentive (PLI) Scheme for High Efficiency Solar PV Modules, India established 18.5 GW of solar module manufacturing capacity by June 2025, including 9.7 GW of solar cell capacity and 2.2 GW of ingot-wafer capacity.
The policy ecosystem supports investment, encourages domestic manufacturing, promotes grid integration, and incentivises adoption among residential and commercial consumers. Additionally, corporate renewable procurement is on the rise, as companies seek to meet ESG targets and secure cost-effective, sustainable power.
Emerging Innovations
India is experimenting with solutions that extend beyond traditional solar farms. Floating solar projects on water bodies and agrivoltaics, which combine solar generation with agriculture, are opening new frontiers for land and water efficiency. Meanwhile, energy storage technologies, including battery systems and pumped hydro, are being deployed to balance the intermittency of solar power, making it more reliable for grid integration.
A Look at the Future
India’s solar sector is entering a phase of strategic expansion and innovation. Rooftop solar adoption is expected to increase in urban and semi-urban regions, while domestic manufacturing of solar modules continues to gain momentum, creating jobs and reducing import dependence. As hybrid systems, storage solutions, and technological innovations mature, India’s solar ecosystem will not only meet energy demands but also drive economic growth sustainably.
