Record solar capacity milestone
India Achieves Record Solar Capacity Expansion: India recorded its highest-ever annual solar capacity addition of 45 GW in 2025–26, marking a major leap in its renewable energy journey. States like Rajasthan, Gujarat, and Tamil Nadu emerged as leading contributors due to favorable climatic and policy conditions.
The country’s cumulative solar capacity reached 150.26 GW as of March 2026, a massive increase from just 2.82 GW in 2014. This reflects India’s rapid transition toward clean energy sources.
Static GK fact: India currently ranks 3rd globally in solar power capacity, according to international renewable energy data.
Factors driving solar growth
India benefits from strong geographical advantages, receiving 300–330 sunny days annually. The average solar radiation ranges between 4–7 kWh per square meter per day, making it highly suitable for solar installations.
Government initiatives have played a critical role in accelerating adoption. Programs like PM Surya Ghar aim to provide rooftop solar systems to one crore households, with 23.9 lakh homes already covered by December 2025.
Static GK Tip: Rooftop solar systems reduce transmission losses and empower decentralized energy production.
Key government initiatives
Several flagship schemes have supported solar expansion. The National Solar Mission focuses on increasing solar deployment, while PM-KUSUM promotes solar usage in agriculture.
Large-scale projects like Solar Parks and Ultra-Mega Solar Power Projects have improved infrastructure and investment flow. The Production Linked Incentive (PLI) scheme has attracted ₹52,900 crore investment to boost domestic solar manufacturing.
These measures are reducing import dependency and strengthening India’s position in the global solar value chain.
Global leadership and initiatives
India has taken a leadership role in global solar cooperation. It is a founding member of the International Solar Alliance, headquartered in Gurugram, promoting solar adoption among tropical countries.
The One Sun One World One Grid (OSOWOG) initiative, launched in 2018, aims to connect renewable energy grids globally. This enhances energy security and enables efficient power distribution across regions.
Static GK fact: OSOWOG envisions a transnational electricity grid powered primarily by renewable energy sources.
Understanding solar energy
Solar energy is harnessed directly from sunlight for electricity generation and heating applications. It is one of the most sustainable and abundant energy sources available.
There are two primary technologies used. Solar photovoltaic (PV) systems convert sunlight directly into electricity using semiconductor materials. Concentrated solar power (CSP) uses mirrors to focus sunlight and generate thermal energy for large-scale power plants.
