India’s solar power capacity has grown from just 2.8 GW in 2014 to over 140 GW in 2025, making it the largest contributor to the country’s renewable energy mix. With a target of 500 GW non-fossil capacity by 2030, solar is now the backbone of India’s clean energy transition.

India’s solar power sector has transformed from a niche renewable segment into the backbone of the country’s clean energy transition. Over the past decade, India has witnessed exponential growth in solar capacity, driven by ambitious government targets, falling technology costs, and rising global climate commitments.

With solar now contributing the largest share of renewable energy, India is steadily moving toward its goal of 500 GW non-fossil fuel capacity by 2030.

India’s Solar Growth Snapshot

India’s solar journey can best be understood through its rapid numerical expansion:

• Total installed solar capacity (Feb 2025): 143.6 GW
  
  

• Capacity (Nov 2025): 132.85 GW (up 41% YoY)
  
  

• Solar crossed 100 GW milestone: January 2025
  
  

• Total renewable capacity (2026): ~267 GW, with solar as the largest share
  
  

This growth marks a dramatic rise from just ~2.8 GW in 2014, reflecting India’s aggressive renewable push.

Record-Breaking Solar Capacity Additions

India is now among the fastest-growing solar markets globally.

Key Annual Additions:

• 2025 solar addition: ~36.6 GW (record high, +43% YoY)
  
  

• Apr–Jan FY26 additions: ~34.96 GW
  
  

• 2025 total renewable additions: 44.5 GW (solar dominated)
  
  

Solar alone accounted for:

• ~88% of renewable capacity additions
  
  

• ~67% of total power capacity additions
  
  

This clearly positions solar as the primary driver of India’s energy expansion.

Utility vs Rooftop Solar: A Dual Growth Story

India’s solar expansion is driven by both large-scale projects and distributed generation.

Utility-Scale Solar:

• Dominates total capacity
  
  

• Over 109 GW from ground-mounted projects
  
  

• Major states: Rajasthan, Gujarat, Maharashtra
  
  

Rooftop Solar:

• 7.1 GW added in 2025 (+123% YoY)
  
  

• Accounts for ~19% of total installations
  
  

• Boosted by schemes like PM Surya Ghar
  
  

Off-Grid & Hybrid:

• Growing in rural and industrial applications
  
  

• Supporting energy access and storage integration
  

Solar Power’s Share in India’s Energy Mix

Solar energy is rapidly reshaping India’s electricity landscape:

• Over 50% of renewable capacity is now solar
  
  

• Solar contributed significantly to daytime electricity demand
  
  

• Renewable energy accounts for ~40% of installed capacity
  
  

This shift is reducing dependence on coal and lowering emissions.

State-Wise Solar Leaders

India’s solar growth is geographically concentrated in high-radiation states:

Top Solar States:

• Rajasthan – largest solar capacity
  
  

• Gujarat – strong industrial solar base
  
  

• Karnataka & Tamil Nadu – early adopters
  
  

• Maharashtra & Andhra Pradesh – fast-growing markets
  
  

These states benefit from:

• High solar irradiation
  
  

• Land availability
  
  

• Policy incentives
  

Key Government Initiatives Driving Solar Growth

India’s solar expansion is policy-led and strategically aligned.

Major Schemes:

• National Solar Mission
  
  

• Production Linked Incentive (PLI) for solar manufacturing
  
  

• PM Surya Ghar: Muft Bijli Yojana (rooftop solar for 1 crore homes)
  
  

• Solar parks and ultra-mega projects
  
  

Policy Push:

• Mandatory domestic sourcing of solar components by 2028
  
  

• Focus on reducing import dependence (especially from China)
  

Solar Manufacturing & Supply Chain Expansion

India is rapidly building its domestic solar manufacturing ecosystem:

• Solar cell capacity expansion underway
  
  

• 7.5 GW cell capacity added in 2025 (H1)
  
  

• Initial ingot & wafer manufacturing capacity emerging
  
  

This shift aims to make India:

• A global solar manufacturing hub
  
  

• Less dependent on imports
  

Future Targets & Projections

India’s solar ambitions are among the most aggressive globally.

Key Targets:

• 500 GW non-fossil capacity by 2030
  
  

• Solar expected to contribute the majority share
  
  

• Solar capacity projected to quadruple by 2035
  
  

Near-Term Outlook:

• 130–140 GW solar addition expected (FY27–FY29)
  
  

• Massive investments in:
  
  

• Grid infrastructure
  
  

• Battery storage
  
  

• Green hydrogen

Market Growth & Investment Trends

India’s solar market is attracting strong domestic and global investment.

• Market expected to grow at ~49.5% CAGR (2026–2030)
  
  

• Large investments from:
  
  

• Adani Green
  
  

• Tata Power
  
  

• Waaree Energies
  
  

Solar is also enabling:

• Lower electricity tariffs
