Solar Subsidy in Delhi 2026: ₹1,08,000 Stacked + GBI Earnings

If you live in Delhi, the solar subsidy Delhi 2026 equation is the most generous in the country — and almost nobody is claiming it correctly. Most homeowners hear "₹78,000 subsidy" from a salesman and stop there. The reality: between the central PM Surya Ghar transfer, the Delhi state government top-up, and the Generation-Based Incentive (GBI) paid every month for five years, a properly-claimed 3 kW system in Delhi is subsidised to the tune of ₹1,08,000 upfront plus another ₹15,000–₹20,000 over five years in GBI.

At Bridgeway Power, with 35+ years in NCR and 5,000+ installations, we file the full stack — central, state, and GBI — for every customer. Here is exactly how the math works in 2026.

Understanding the Stacked Delhi Subsidy

There are three separate cash benefits for a Delhi rooftop solar system. They are not exclusive — you get all three.

1. PM Surya Ghar (Central — DBT to your bank)

2. Delhi State Top-Up (Capital Subsidy)

Delhi government adds ₹10,000 per kW, capped at ₹30,000 for residential consumers. This is paid in addition to the central CFA after net meter installation and is credited directly via the Delhi Solar Portal.

3. Delhi GBI (Generation-Based Incentive — 5 years)

This is the part nobody talks about. Delhi pays you per unit generated for the first five years from commissioning:

RWAs also get an ₹18,000 per kW capital subsidy from the Delhi government — separate from the residential ₹30,000 cap.

The Real Net-Cost Example: 3 kW in Delhi

A 3 kW residential rooftop in South Delhi (BSES Rajdhani territory), installed at 2026 prices:

After five years, the effective net cost is closer to ₹28,000 for a system that will run another 20 years and offset a ₹3,000–₹4,000 monthly bill. That is a payback under three years.

DISCOM-Specific Net Metering in Delhi

All four Delhi DISCOMs offer bidirectional net metering for systems 1 kW to 500 kW:

• BSES Rajdhani (BRPL) — South & West Delhi. Net meter typically installed within 15–20 working days of application.
• BSES Yamuna (BYPL) — Central & East Delhi. Similar timeline, slightly heavier paperwork.
• Tata Power Delhi Distribution (TPDDL) — North & North-West Delhi. Fastest of the four, often inside 10 working days.
• NDMC — Lutyens' Delhi. Smallest customer base, application is manual.

Bridgeway Power files all DISCOM paperwork at zero cost — feasibility, load enhancement (if needed), CEIG approval for systems above 10 kW, and the national portal commissioning.

Why Delhi's Tariff Makes Solar Non-Optional

Delhi residential tariffs (BSES/TPDDL) under the latest DERC order:

The Delhi government's free-power scheme does not apply to households consuming above 200 units — which is virtually every 2 BHK with an AC. Solar is how middle-class Delhi homes escape the ₹6.50–₹8/unit slabs entirely.

Documents Required

To file your PM Surya Ghar Delhi application along with the Delhi state top-up and GBI registration, you need:

• Aadhaar card of the applicant
• Latest electricity bill (within last 3 months)
• Cancelled cheque or bank passbook for DBT
• Passport-size photograph
• Rooftop photographs (3–4 angles)
• Property ownership proof (registry, allotment, or bill in your name)
• For RWAs: society resolution authorising the installation

Common Mistakes that Cost Delhi Homeowners Money

1. Installing above 3 kW without checking the GBI breakpoint

Going from 3 kW to 4 kW drops your GBI rate from ₹3/unit to ₹2/unit on every unit generated. Sometimes a 3 kW system pays back faster than a 5 kW system in Delhi.

2. Skipping the Delhi state portal

Some installers only file the central PM Surya Ghar form. The ₹30,000 Delhi top-up requires a separate application on solar.delhi.gov.in. If your installer didn't tell you about it, you left ₹30,000 on the table.

3. Not registering for GBI at commissioning

GBI is opt-in at the time of commissioning. If you miss this window, recovering it is a multi-month exercise.

Why 2026 is the Right Year for Delhi Solar

1. DERC slab inflation: Tariffs above 400 units have moved up roughly 6% year-on-year. Solar locks in your effective unit cost for 25 years.
2. Pollution-linked policy: Delhi's solar push is structurally tied to GRAP. Subsidy cuts are unlikely in the next two years.
3. Property value: A solar-powered home in Dwarka, Vasant Kunj, or Pitampura commands a measurable premium in resale listings.

Frequently Asked Questions

Is the Delhi state subsidy of ₹30,000 still available in 2026?

Yes. The Delhi government's capital subsidy of ₹10,000 per kW (capped at ₹30,000 for residential) is active under the Delhi Solar Policy 2024 and continues through 2026. It is filed separately from the central PM Surya Ghar subsidy.

How does Delhi GBI compare to net metering credit?

They are independent. Net metering credits you for exported units at your retail tariff. GBI pays you ₹2–₹3 per unit on every generated unit (whether exported or self-consumed) for the first 5 years. You get both.

Can I claim solar subsidy if I live in a Delhi apartment?

Yes — either via your RWA for a society-wide installation (RWAs get ₹18,000/kW capital subsidy plus ₹2/unit GBI), or individually if you own exclusive rooftop access. See our guide on solar for builder floors.

How long does the Delhi solar subsidy process take?

Survey to commissioning is typically 30–45 days. Central subsidy DBT lands within 30 days of commissioning; Delhi state top-up takes another 45–60 days; GBI starts accruing from month 1 and is paid quarterly into your bank account.

Does Delhi GBI apply to commercial properties?

Yes, at ₹1 per unit for 5 years. Combined with accelerated depreciation, commercial payback in Delhi is typically under 3.5 years.

Is loan or EMI available for Delhi solar systems?

Yes. PSU banks (SBI, Union, Canara) offer 7-year solar loans at 10–10.5% under PM Surya Ghar. On a 3 kW system in Delhi, EMI starts around ₹1,800/month — less than the bill it eliminates.

Conclusion

The solar subsidy Delhi 2026 stack — ₹78,000 central + ₹30,000 state + 5 years of GBI — makes Delhi the single most subsidised rooftop solar market in India. A 3 kW system that lists at ₹2,01,000 effectively costs a Delhi homeowner under ₹30,000 over its first five years.

The catch is filing all three correctly. Bridgeway Power handles the entire stack — central DBT, Delhi state portal, GBI registration, BSES/TPDDL net metering, and commissioning — at zero processing fee.

FAQ

How much subsidy do I get on a rooftop solar system in Delhi?

Delhi residents get a stacked subsidy of up to ₹1,08,000 for a 3 kW system — ₹78,000 from the PM Surya Ghar central scheme plus ₹30,000 from the Delhi state top-up (₹10,000 per kW, capped at 3 kW). This is the highest household subsidy stack in India today.

What is the net cost of a 3 kW system in Delhi after subsidy?

At ~₹68,600/kW installed, a 3 kW system is ~₹2,05,800 gross. After the ₹1,08,000 combined subsidy, the net out-of-pocket cost is roughly ₹97,800 for a Delhi homeowner.

Who is eligible for the Delhi solar subsidy?

Any residential BSES or Tata Power consumer with a rooftop, valid electricity connection, and structural feasibility clearance can apply. There is no income cap, but the connection must be in the applicant's name.

How long does the Delhi subsidy DBT take?

Subsidy is disbursed by the central government via DBT within 30–45 days of inspection and net-meter commissioning. The state top-up follows a similar window through the Delhi discom.
