India rooftop solar 30 GW target: tracking the gap with 18 months to go

India has installed roughly 14 GW of rooftop solar against the 30 GW national target. With 18 months remaining, closing the 16 GW gap requires a 3× pace acceleration. PM Surya Ghar Muft Bijli Yojana subsidy uptake has accelerated since Q4 2025, but DISCOM net-metering bottlenecks remain the binding constraint.

In 50 words: India has installed about 14 GW of rooftop solar against the 30 GW target. With 18 months to go, closing the 16 GW gap demands a 3× pace acceleration. The PM Surya Ghar subsidy is helping, but DISCOM net-metering bottlenecks remain the binding constraint nobody has solved.

Where we are

Cumulative installed rooftop solar capacity in India hit approximately 14 GW by end-March 2026. The national target — set in 2024 — is 30 GW by end-September 2027. That leaves a 16 GW gap over 18 months.

What's working

  • PM Surya Ghar Muft Bijli Yojana subsidy disbursements crossed ₹4,200 crore by April 2026, with installations under the scheme nearing 800,000 units.
  • Residential adoption in tier-2 cities accelerating, particularly in Gujarat, Maharashtra, Rajasthan, Karnataka.
  • Module prices falling 7% QoQ are pulling effective customer payback below 4 years.

What isn't

  • DISCOM net-metering bottlenecks. Sanction delays of 60–120 days remain the most-cited customer complaint.
  • C&I segment slowdown. Commercial and industrial rooftop installations decelerated in Q1 2026, partly due to behind-the-meter BESS competition for the same capex budget.
  • State-level inconsistency. Tamil Nadu, Telangana, and West Bengal lagging well below their state targets.

What 3× acceleration would actually need

Hitting 30 GW by September 2027 requires roughly 900 MW/month average vs current 350 MW/month. Plausible if:

  1. DISCOM net-metering approvals shift to 30-day SLAs (current draft policy under review)
  2. C&I segment reactivates as BESS-bundled offerings mature
  3. Vendor financing reaches residential customers more broadly (currently <15% of installations)

What to watch next

The next two quarterly tracker updates will tell the story. If monthly installations cross 600 MW by Q3 2026, the 30 GW target enters the realm of stretch-but-achievable. If they stay at 350 MW, the target slips to 2028.
