Union Budget 2026-27 — What Changed for Solar Energy in India

The Union Budget presented on February 1, 2026 gave a massive push to India's solar sector. Total renewable energy allocation increased 30% to ₹3.29 lakh crore, with solar getting the lion's share. Here's everything that changed and what it means for you.

Key Budget 2026 Solar Announcements

Item2025 Allocation2026 AllocationChange
Total Solar Sector₹2,42,240 crore₹3,05,390 crore+26%
PM Surya GharNot separately disclosed₹22,000 croreMajor increase
PM-KUSUM₹2,600 crore₹5,000 crore+92%
Total Renewables₹2,53,190 crore₹3,29,147 crore+30%

Customs Duty Changes — Impact on Solar Prices

Good News — Duties Reduced

  • Sodium Antimonate (raw material for solar glass): BCD reduced from 7.5% → Nil
  • Solar modules: Effective duty reduced to 20% through rebalancing of BCD and cess
  • Solar cell duties: Lowered via duty structure rebalancing
  • Capital goods for lithium-ion (BESS) manufacturing: BCD exemptions extended
  • Critical mineral processing equipment: BCD exempted

Watch Out — BCD Exemptions Expiring

  • BCD exemptions for silicon used in un-diffused wafers will lapse from April 1, 2026
  • This may slightly increase upstream manufacturing costs but impact on end consumer is minimal

What This Means for Solar Buyers

  • Solar module prices expected to remain stable or decrease slightly as manufacturing input costs fall
  • Battery storage (BESS) systems will become more affordable — extended capital goods exemptions reduce manufacturing cost
  • Domestic manufacturing (PLI) gets stronger support — more Indian-made panels available
  • PM Surya Ghar funding secured for 2026-27 — subsidy payments will continue without disruption

New Financial Infrastructure — Infrastructure Risk Guarantee Fund

Budget 2026 introduced a new Infrastructure Risk Guarantee Fund that provides partial credit guarantees to banks lending for large Battery Energy Storage System (BESS) projects. This makes grid-scale battery storage bankable — crucial for managing India's growing solar surplus during peak afternoon hours.

CCUS Fund — ₹20,000 Crore

Budget 2026 announced a ₹20,000 crore Carbon Capture, Utilization and Storage (CCUS) fund. While not directly solar-related, this signals India's long-term clean energy commitment and creates new opportunities for solar+storage projects.

What Budget 2026 Did NOT Do

  • No new dedicated income tax deduction for individual solar buyers (existing provisions apply)
  • Subsidy cap of ₹78,000 per household was not increased (CFA rate was increased in January 2026 separately)
  • No change in GST rate on solar systems (remains at 5%)

Overall Impact on Solar Sector

Budget 2026 is strongly positive for India's solar sector:

  • Record funding ensures scheme continuity through 2026-27
  • Nearly doubled PM-KUSUM budget benefits 5 crore+ farmers
  • Customs duty relief reduces system costs
  • BESS support ensures grid can absorb more solar — removes a key scaling barrier
  • India's solar sector grew 43% in 2025 (36.6 GW added) — Budget 2026 sustains this momentum
