Here’s a question most Delhi homeowners are asking right now:
My electricity bill keeps going up every summer. Is there actually a government scheme that fixes this, or is it just another thing that sounds good on paper?
The honest answer is: PM Surya Ghar Muft Bijli Yojana is real, the subsidy money is real, and thousands of Delhi households have already used it to bring their electricity bills down to near zero. But the process involves your specific DISCOM – BSES Rajdhani, BSES Yamuna, or TPDDL and that’s where most people get confused and give up.
This guide cuts through all of that. By the end, you’ll know exactly whether you’re eligible, how much subsidy you’ll get, and the precise steps to apply based on which DISCOM supplies your electricity.
Delhi Electricity Subsidy 2026: How to Check Your Eligibility and Apply Online
PM Surya Ghar Muft Bijli Yojana is the central government’s flagship rooftop solar scheme, launched in February 2024 with a ₹75,021 crore outlay.
The goal is simple: install solar panels on one crore Indian homes by 2027, give households up to 300 free units of electricity per month, and pay them a direct subsidy to make the installation affordable.
For Delhi specifically, the scheme runs through the city’s three distribution companies BSES Rajdhani (BRPL), BSES Yamuna (BYPL), and TPDDL (Tata Power Delhi Distribution Limited). Your application is routed through whichever of these supplies your home, and they handle the technical feasibility check, net meter installation, and subsidy coordination with MNRE.
| DISCOM | Area Covered | Apply At |
| BSES Rajdhani (BRPL) | South & West Delhi | solar.delhi.gov.in or pmsuryaghar.gov.in |
| BSES Yamuna (BYPL) | East & Central Delhi | solar.delhi.gov.in or pmsuryaghar.gov.in |
| TPDDL (Tata Power) | North & Northwest Delhi | pmsuryaghar.gov.in or tatapower-ddl.com |
Not sure which DISCOM you’re under?
Check the top of your electricity bill, the company name is printed there. BSES Rajdhani covers South and West Delhi, BSES Yamuna covers East and Central Delhi, and TPDDL covers North and Northwest Delhi.
Are You Eligible? Check Before You Apply
The eligibility criteria are straightforward. You qualify if:
- You own a residential property in Delhi with a valid electricity connection
- Your rooftop has adequate shadow-free space (roughly 10 sq ft per 100W of capacity)
- You have not previously availed any central solar subsidy for the same property
- Your electricity connection is in your name or a family member’s name
- Your building structure can support panel mounting (most RCC rooftops qualify)
Renters are generally not eligible unless the property owner applies. Flats in group housing societies can apply collectively through their RWA this actually unlocks better per-unit economics.
Quick check
- Residential property owner in Delhi
- Active electricity connection (BSES or TPDDL)
- Shadow-free rooftop space available
- No previous central solar subsidy on this premises

How Much Subsidy Will You Get? (2026 Slab Breakdown)
The central subsidy under PM Surya Ghar is directly credited to your bank account after installation is verified. Here are the current slabs:
| System Size | Cost Before Subsidy | Central Subsidy | Your Cost After Subsidy |
| 1 kW | ₹55,000 – ₹70,000 | ₹30,000 | ₹25,000 – ₹40,000 |
| 2 kW | ₹1,10,000 – ₹1,35,000 | ₹60,000 | ₹50,000 – ₹75,000 |
| 3 kW | ₹1,60,000 – ₹1,90,000 | ₹78,000 | ₹82,000 – ₹1,12,000 |
| 4 kW | ₹2,10,000 – ₹2,50,000 | ₹78,000 | ₹1,32,000 – ₹1,72,000 |
| 5 kW | ₹2,60,000 – ₹3,00,000 | ₹78,000 | ₹1,82,000 – ₹2,22,000 |
| 6–10 kW | ₹3,40,000 – ₹5,50,000 | ₹78,000 (capped) | ₹2,62,000 – ₹4,72,000 |
A few things worth knowing about the subsidy structure: systems above 3 kW are capped at ₹78,000 regardless of size. You can install a larger system 5 kW, 8 kW, 10 kW but the subsidy won’t increase beyond that cap. The subsidy is paid directly to you (not the vendor), which protects against overcharging.
For most Delhi families with a monthly bill of ₹2,500–₹5,000, a 3 kW system hits the sweet spot it generates 300–360 units per month under Delhi’s sun conditions, covers the majority of average household consumption, and gets you the full ₹78,000 subsidy.
How to Apply Online – Step by Step
The application is fully digital. Here’s exactly what to do:
| Step | Action | Details |
| 01 | Register on the national portal | Go to pmsuryaghar.gov.in. Click ‘Apply for Rooftop Solar’. Register with your mobile number, state (Delhi), and DISCOM (BRPL / BYPL / TPDDL). |
| 02 | Enter your consumer number | This is your electricity account number printed on your bill. This links your application to your DISCOM account. |
| 03 | Fill in rooftop details | Enter your address, approximate rooftop area, and preferred system capacity. The portal has a built-in calculator to guide sizing. |
| 04 | Submit documents | Upload a recent electricity bill, Aadhaar card, PAN card, and a passport photo. House ownership proof is required if the bill is not in your name. |
| 05 | Wait for DISCOM feasibility approval | Your DISCOM (BSES or TPDDL) reviews technical feasibility grid capacity, transformer load, net meter availability. Typically takes 7–15 working days. |
| 06 | Select an empanelled vendor | Once approved, choose a government-empanelled installer from the portal’s vendor list. Unapproved installers make you ineligible for subsidy. |
| 07 | Installation & inspection | Installation takes 1–2 days. After completion, DISCOM conducts an official inspection and installs the bi-directional net meter. |
| 08 | Subsidy credited to your bank | Submit commissioning certificate and net meter details on the portal. MNRE processes subsidies directly to your bank account usually within 30–60 days. |
Net Metering in Delhi: What Happens to Excess Units
Net metering is what makes rooftop solar financially powerful. When your panels generate more electricity than you’re using commonly during afternoons when you’re out the excess flows back into the BSES or TPDDL grid. At the end of the month, those exported units are deducted from your consumption units, and you only pay the difference.
In practical terms: a 3 kW system generating 350 units in a month, used against a household consuming 250 units, means 100 units exported. Those 100 units are credited at the applicable rate bringing your payable units to zero or even creating a credit that carries forward.
Delhi net metering:
- BSES Rajdhani & BSES Yamuna: Apply via solar.delhi.gov.in
- TPDDL: Apply via pmsuryaghar.gov.in or tatapower-ddl.com
- Bi-directional meter installed by your DISCOM after inspection
Monthly bill reconciliation excess units carry forward
A Real Example: What This Looks Like for a Delhi Family
Consider a family in Dwarka (BSES Rajdhani area) with a monthly electricity bill of ₹4,200. They install a 3 kW on-grid system.
- System cost before subsidy: ₹1,72,000
- PM Surya Ghar subsidy received: ₹78,000
- Net cost after subsidy: ₹94,000
- Monthly generation (Delhi avg.): 330–370 units
- Monthly bill after solar: ₹300–₹600 (mostly fixed charges)
- Annual savings: approx. ₹42,000–₹46,000
- Payback period: under 2.5 years
- System lifespan: 25 years
After payback, the family essentially generates free electricity for 22+ years. That’s the part most people don’t fully account for when they’re comparing upfront costs.
Common Mistakes Delhi Applicants Should Avoid
- Using a non-empanelled vendor this disqualifies you from the subsidy entirely, no exceptions
- Not linking your correct bank account to the portal before applying subsidy transfer fails if details don’t match
- Applying for a system size much larger than your consumption over-sizing doesn’t increase subsidy and slows DISCOM approval
- Missing the inspection window if DISCOM schedules an inspection and you’re unavailable, timelines reset
- Paying the full amount to the vendor before subsidy is credited your subsidy goes to you, so clarify payment terms with the vendor upfront
The Bottom Line
PM Surya Ghar Muft Bijli Yojana is one of the most straightforward government schemes available to Delhi homeowners right now. The subsidy is substantial, the application is online, and the payback period especially in Delhi’s summer-heavy electricity consumption pattern is genuinely short.
The key is getting the DISCOM step right. Whether you’re under BSES Rajdhani, BSES Yamuna, or TPDDL, the process is the same at the national portal but knowing your DISCOM upfront saves you from confusion mid-application.
If your electricity bill is above ₹2,000 per month and you own your rooftop in Delhi, the question isn’t really whether solar makes sense. The question is how soon you want to start saving.
