·
> **Quick Summary** > - **Primary Scheme:** PM Surya Ghar Muft Bijli Yojana + Delhi State Top-Up > - **Stacked Subsidy:** ₹78,000 (central) + ₹30,000 (Delhi) = **₹1,08,000** on a 3 kW system > - **Plus Delhi GBI:** ₹2–₹3 per generated unit for 5 years > - **Monthly Savings:** ₹3,500 – ₹12,000 (depending on system size and BSES/TPDDL slab) > - **Payback Period:** 3 – 4 years > - **Applicable DISCOMs:** BSES Rajdhani, BSES Yamuna, TPDDL, NDMC
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)
| System Capacity | Central Subsidy | | :--- | :--- | | **1 kW** | ₹30,000 | | **2 kW** | ₹60,000 | | **3 kW and above** | ₹78,000 (capped) |

### 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:
| Consumer Type | GBI Rate | Duration | | :--- | :--- | :--- | | Residential ≤ 3 kW | ₹3 per unit | 5 years | | Residential 3–10 kW | ₹2 per unit | 5 years | | RWA (up to 500 kW) | ₹2 per unit | 5 years | | Commercial | ₹1 per unit | 5 years |
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:
| Line item | Amount | | :--- | :--- | | Gross system cost (3 kW × ₹67,000/kW) | ₹2,01,000 | | Less: PM Surya Ghar central subsidy | – ₹78,000 | | Less: Delhi state top-up (3 × ₹10,000) | – ₹30,000 | | **Net cost out of pocket** | **₹93,000** | | Plus: Delhi GBI (≤ 3 kW @ ₹3/unit × 360 units/mo × 60 months) | – ₹64,800 over 5 years |
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:
| Slab | Per-unit rate | | :--- | :--- | | 0–200 units | ₹3.00 (with 100% subsidy below 200) | | 201–400 units | ₹4.50 | | 401–800 units | ₹6.50 | | 801–1,200 units | ₹7.00 | | Above 1,200 | ₹8.00+ |
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.
