India added 45 GW of Solar Energy Capacity in 2025-26, with Rajasthan, Gujarat and Tamil Nadu emerging as top contributing states.
Solar Energy in India
- Solar Power (Cumulative) : 150.26 GW as on 31st March, 2026 (Increased by 147.44 GW from 2.82 GW in 2014).
- Global Rank: India ranks 3rd (as per IRENA Renewable Energy Statistics 2025).
Reasons for Significant Progress in India’s Solar Energy
- Regional Suitability: Most parts of India have 300 - 330 sunny days annually with average solar incidence stands at around 4 - 7 kWh/sq. meter/day.
- Favourable Government Schemes:
- PM Surya Ghar: Launched in 2024 to provide rooftop solar systems to one crore households (As of December 2025, 23.9 lakh households have already installed it ).
- Others: PM-KUSUM,National Solar Mission, Solar Parks & Ultra-Mega Solar Power Projects, etc.
- Boosting Domestic Manufacturing Capacity: Production-Linked Incentive (PLI) Scheme for Solar PV to achieve Giga Watt (GW)-scale manufacturing capacity in high-efficiency solar PV modules attracted ₹52,900 crore investment (as on September 2025).
- Global Leadership: India is founding member of International Solar Alliance (headquartered in Gurugram); Initiated One Sun, One World, One Grid (OSOWOG) in 2018 focussing on interconnecting renewable energy grids.
