Impact of Union Budget 2026-27 on India’s Solar PV Industry

Union Budget 2026-27 keeps solar on a clear growth track— especially residential rooftop solar and grid-scale battery storage. For the industry, the biggest story is where the money is going (rooftop + storage) and what changes in import duties mean for manufacturing inputs and procurement.

Below is a short, stakeholder-focused breakdown you can act on.

Union Budget 2026-27: Rooftop solar + battery storage get a clear boost. Here’s what it means for homeowners and the solar industry.

What Budget 2026-27 signals for solar

1) Rooftop solar gets a stronger push (PM Surya Ghar)

The outlay for PM Surya Ghar: Muft Bijli Yojana is ₹22,000 crore (BE 2026-27), up from ₹20,000 crore (BE 2025-26) and ₹17,000 crore (RE 2025-26).

Why it matters: more budget room typically means faster processing capacity (vendor ecosystem + DISCOM workflows) and a better chance of steady subsidy releases—key for homeowner confidence.

2) Storage support jumps sharply (good news for solar + grid stability)

Viability Gap Funding (VGF) for Battery Energy Storage Systems rises to ₹1,000 crore (BE 2026-27), versus ₹200 crore (BE 2025-26) and ₹100 crore (RE 2025-26).

Why it matters: storage reduces curtailment risk, improves peak management, and makes solar power more valuable during evening demand—especially important as more renewables come online.

3) Grid-solar and farm-solar continue (steady, not flashy)

• Solar Power (Grid): ₹1,775 crore (BE 2026-27)
• KUSUM: ₹5,000 crore (BE 2026-27)

What to read between the lines: rooftop + storage are getting the strongest incremental signals this year.

4) Broader capex remains high (indirect boost to energy infra)

Budget documents show capital expenditure of ₹12,21,821 crore (BE 2026-27).

Why it matters for solar: stronger public capex supports transmission, evacuation, and infrastructure—areas that often become bottlenecks for large-scale renewable integration.

What this means for Indian homeowners

Rooftop solar remains a “supported decision” in 2026

A bigger outlay improves the scheme’s ability to keep installations moving.

Reality check on adoption: As of 09 Dec 2025, the government reported 19,45,758 RTS systems installed and 24,35,196 households benefited under PM Surya Ghar, along with subsidy and loan progress.

Practical homeowner checklist (keep it simple)

• Do a shadow/roof check first (trees, water tank shadows, terrace room, parapet height).
• Ask for a written BOM + wiring/earthing plan (SPD, DC isolator, earthing pits, cable routing).
• If your area has frequent outages, consider a hybrid inverter (battery-ready) so you don’t redo the system later.
• Plan your install timing: demand usually spikes after budget season—book site survey early to avoid installer backlogs.

What this means for installers, EPCs, and distributors

Expect demand, but execution will decide winners

When rooftop accelerates, customer pain points are usually:

• delays in approvals/inspections
• poor earthing/SPD practices
• monitoring app setup issues
• slow after-sales

Action items for 2026:

• standardize a commissioning checklist (photos + test readings)
• keep a 1-page handover pack (single-line diagram, warranties, app login)
• train teams on safety + DC side best practices (this reduces callbacks)

What this means for C&I and utility-scale developers

Storage is no longer “optional”

With VGF support rising, more tenders will favor hybrids and dispatchable RE structures.

What to do now:

• build bid models with solar + storage scenarios (not just plain solar)
• focus on sites with evacuation clarity and realistic commissioning schedules
• treat O&M + performance guarantees seriously (storage adds new failure modes)

What this means for solar manufacturing & importers (duties and supply chain)

1) Solar glass input gets cheaper

Basic customs duty on sodium antimonate (used in solar glass manufacture) is reduced from 7.5% to NIL, effective 2 Feb 2026.

2) Watch this deadline: silicon/wafer-related NIL BCD entry lapsing

A NIL BCD entry covering silicon in all forms for undiffused silicon wafers, and undiffused silicon wafers for solar cells/modules, is allowed to lapse on 31 March 2026.

Practical implication: if your BOM depends on these concessions, re-check landed cost assumptions for FY 2026-27 procurement.

3) Battery manufacturing capex concession extends to BESS

The customs changes also extend the BCD exemption on certain capital goods used for manufacturing lithium-ion cells to cover batteries for Battery Energy Storage Systems (BESS).

A broader policy framing around tariff cuts for manufacturing and clean-energy supply chains was also reported by Reuters.

Quick action plan by stakeholder

Homeowners

• lock a site survey + quote this quarter
• choose on-grid for best ROI (stable grid) or hybrid-ready (frequent outages)

Installers/EPCs

• tighten process: approvals, documentation, safety checks
• prioritize quality (SPD/earthing) to cut callbacks

Developers

• model projects with storage pathways
• prioritize execution-ready sites (evacuation + schedule realism)

Manufacturers/importers

• plan for post–31 March 2026 duty scenarios (silicon/wafers)
• revisit contracts and buffers for BOM cost volatility
