India Solar Energy 2026 — Progress Report & 2027 Targets

India's solar sector had a record-breaking 2025 — adding 36.6 GW of solar capacity, a 43% jump over 2024. The country now has 135.8 GW of total installed solar capacity and crossed the historic 100 GW solar milestone in January 2025. Here's a full progress report and what to expect in 2026-2027.

India's Path to 500 GW by 2030

India pledged 500 GW of non-fossil capacity by 2030 at COP26. Here's where we stand:

  • Current non-fossil installed capacity: 262.74 GW (52.5% of the 500 GW target achieved)
  • Required addition in remaining 4 years (2026-2030): ~237 GW
  • At 2025's record pace of 36.6 GW/year: 146 GW more in 4 years — will fall short
  • Pace needs to increase to ~60 GW/year to hit the 2030 target
  • Government confident: Budget 2026 funding + PLI manufacturing scale-up expected to accelerate additions

State-Wise Solar Leaders (2025)

StateInstalled Solar CapacityRank
Rajasthan~32 GW#1
Gujarat~25 GW#2
Karnataka~20 GW#3
Tamil Nadu~16 GW#4
Andhra Pradesh~15 GW#5

Rooftop Solar Target — 30 GW by 2027

  • Current rooftop solar: ~6.38 GW (PM Surya Ghar alone) + commercial rooftop
  • Target: 30 GW rooftop by FY 2027
  • The 1 crore household target (March 2027) would add ~3 GW alone
  • Gap: Significant — requires massive acceleration in both residential and commercial rooftop

Key Drivers for 2026-2027 Solar Growth

  • PM Surya Ghar: ₹22,000 crore budget ensuring continued subsidies
  • Falling costs: Solar now the cheapest electricity source at ₹2-3/unit
  • Battery storage: Falling BESS prices enabling 24/7 solar use
  • PLI manufacturing: Domestic panel supply scaling rapidly
  • Green energy demand: India Inc's RE100 commitments driving corporate solar demand
  • Agricultural solar: PM-KUSUM 2.0 bringing millions of farmers to solar

What This Means for You

  • If you're considering solar — install now while PM Surya Ghar subsidies are fully funded
  • Solar panel prices will continue to fall but subsidies may evolve — don't wait too long
  • Net metering policies are most favorable right now — future policies may shift to storage-integrated models
  • India's grid is becoming more solar-friendly with BESS integration — longer-term, solar-only systems become even more valuable
