Delhi’s PM Suryaghar landscape in 2026 is defined by one critical question: which DISCOM covers your colony? Three electricity distributors operate in Delhi — BSES Rajdhani (South and West), BSES Yamuna (East and Central), and TPDDL (North and Northwest). Each has a separate PM Suryaghar application process, different consumer number formats, and slightly different timelines. The PM Suryaghar subsidy itself — ₹78,000 for systems of 3 kW and above — is identical across all three.
Key takeaway. PM Suryaghar in Delhi gives residential consumers ₹78,000 subsidy on 3 kW+ rooftop solar across BSES Rajdhani, BSES Yamuna, and TPDDL. Delhi gets 5.0–5.5 peak sun hours daily, and DISCOM feasibility takes 12–20 days. A 3 kW system post-subsidy costs ₹1,20,000–₹1,55,000. Heaven Green Energy handles PM Suryaghar applications across all three Delhi DISCOMs.
Delhi’s solar adoption has grown sharply since 2024 — MNRE data shows Delhi ranking among the top 5 states for residential solar installations in 2025. The combination of high tariffs (up to ₹8.00/kWh), generous sunlight during summer months, and the ₹78,000 subsidy makes Delhi one of India’s better residential solar markets despite its complex three-DISCOM environment.
Delhi’s Three DISCOMs: A Complete Coverage Map
Understanding which DISCOM covers your area is the single most important step in Delhi’s PM Suryaghar process. An application filed under the wrong DISCOM is automatically rejected.

PM Suryaghar Subsidy for Delhi Consumers
The PM Suryaghar subsidy is set by MNRE and is identical across BSES Rajdhani, BSES Yamuna, and TPDDL:
| System Size | Subsidy | After-Subsidy System Cost (Delhi) |
|---|---|---|
| 1 kW | ₹30,000 | ₹60,000–₹80,000 |
| 2 kW | ₹60,000 | ₹90,000–₹1,15,000 |
| 3 kW | ₹78,000 | ₹1,20,000–₹1,55,000 |
| 5 kW | ₹78,000 | ₹1,80,000–₹2,30,000 |
| 10 kW | ₹78,000 | ₹3,25,000–₹4,15,000 |
The subsidy amount does not increase beyond ₹78,000 for any system over 3 kW — the additional capacity beyond 3 kW is paid at market cost. This is why right-sizing to your actual consumption is important. A 3 kW system that covers 80% of your bill typically offers better financial returns than a 5 kW system with the same ₹78,000 subsidy and significant export surplus.
The Delhi 3-DISCOM PM Suryaghar Application Process
The application process is largely identical across the three DISCOMs, with the key difference being the consumer number format and DISCOM-specific processing teams:
- Identify your DISCOM from your electricity bill. This is mandatory — wrong selection resets your application.
- Register on pmsuryaghar.gov.in — use your registered mobile number. Once registered, apply using your DISCOM consumer number from your bill.
- Select your DISCOM correctly — choose “BSES Rajdhani”, “BSES Yamuna”, or “TPDDL” as appropriate. Delhi is listed under the Delhi state option.
- Choose an MNRE-empanelled vendor — Heaven Green Energy is empanelled for all three Delhi DISCOMs.
- Upload required documents:
- Aadhaar card (of the account holder)
- Latest electricity bill (clearly showing consumer number and DISCOM name)
- Property ownership proof (sale deed for owned; NOC/registered rent agreement for tenants)
- Bank account details for DBT (account in the name of the account holder)
- Passport-size photograph
- DISCOM feasibility check — all three DISCOMs take 12–20 working days. They assess transformer capacity, connected load, and technical suitability.
- System installation — vendor installs after feasibility approval. Typical Delhi residential installation: 1–3 days.
- DISCOM post-installation inspection — 12–25 days for inspection and net meter installation.
- Subsidy DBT — ₹78,000 transferred within 30 days of commissioning.

💡 Fast tip
DERC (Delhi Electricity Regulatory Commission) allows net metering for systems up to the contracted (sanctioned) load. Before applying for PM Suryaghar, check your contracted load on your electricity bill. If you want to install a 5 kW system but your contracted load is only 3 kW, apply for a load enhancement first.
The Delhi PM Suryaghar Eligibility Check
The Delhi PM Suryaghar Eligibility Check is Heaven Green Energy’s proprietary 5-point checklist to confirm a Delhi consumer qualifies for the subsidy before any application is filed — saving 2–4 weeks of wasted time on ineligible applications.
Point 1 — Residential connection confirmed? Only LT domestic (residential) connections are eligible. If your bill says “Commercial,” “Industrial,” or “Agricultural,” the PM Suryaghar subsidy does not apply. Check the “Category” field on your bill.
Point 2 — Single consumer number per application? Each consumer number can have only one PM Suryaghar application. If you have multiple meters at the same property (e.g., a meter for your flat and a separate meter for a parking area or shop), only the residential meter qualifies.
Point 3 — System size within contracted load? System size must be ≤ contracted load. If contracted load = 3 kW, maximum system size = 3 kW (or slightly below). DERC allows up to 90% of contracted load in most DISCOM guidelines.
Point 4 — Roof area available? Minimum roof area required per kW: 8–10 m² of shadow-free space. For a 3 kW system: 24–30 m². For many Delhi DDA flats with partial terrace access, this limits the system to 2–3 kW.
Point 5 — Bank account in consumer’s name? DBT is released only to a bank account registered in the same name as the electricity consumer. If your bill is in your father’s name but you live there, the DBT account must be your father’s. Mismatches cause subsidy delays of 30–90 days.
Delhi Net Metering: How It Works Under DERC
DERC (Delhi Electricity Regulatory Commission) governs net metering in Delhi. Key rules for 2026:
- Net metering is available for residential solar systems from 1 kW up to the contracted load.
- Surplus units exported to the grid are credited against future imports at the applicable import tariff.
- Credits are carried forward monthly and settled annually. Remaining credits at year-end are paid by the DISCOM at a DERC-set feed-in tariff.
- Anti-islanding: all grid-tie inverters must comply with IEEE 1547 or IS 16221 Part 2 anti-islanding requirements. DISCOM inspectors verify this during post-installation inspection.
The net metering guide for India covers DERC’s framework in detail alongside other state regulations.
📘 Regulation note
DERC's net metering order specifies that residential consumers must use BIS-certified solar panels (conforming to IS 14286) and BIS-certified inverters. DISCOM inspectors check BIS certificate numbers during post-installation inspection. A missing BIS number on either the panel or inverter is the most common reason for BSES and TPDDL inspection rejection in Delhi — costing 3–6 weeks in reprocessing time.
Common PM Suryaghar Mistakes Delhi Consumers Make
-
1
Selecting the wrong DISCOM on the national portal — this is the most common Delhi mistake. Selecting BSES Yamuna when you're a TPDDL consumer means BSES receives your application and rejects it after 12–20 days. You then restart from scratch with the correct DISCOM.
-
2
Installing without RWA (Resident Welfare Association) approval — Delhi law and DISCOM regulations require written permission from the colony's RWA or housing society before installation. Without it, you risk the DISCOM refusing to inspect and commission the system.
-
3
Using a vendor not empanelled for your specific DISCOM — some vendors are empanelled for BSES but not for TPDDL, or vice versa. Confirm empanelment on the national portal before signing any agreement.
Is PM Suryaghar Worth It in Delhi?
- ₹78,000 subsidy available across all three DISCOMs
- High upper-slab tariffs (₹8.00/kWh) make savings significant
- Summer peak generation aligns with peak AC billing season
- DERC's mature net metering framework is well-tested
- Three-DISCOM complexity increases documentation risk
- Winter fog (December–January) reduces generation by 20–30%
- RWA approvals add 2–6 weeks in apartment complexes
- End-to-end timeline of 65–100 days is longer than Gujarat

Frequently Asked Questions
How do I find my Delhi DISCOM from my electricity bill?
The DISCOM name is in the header of your monthly electricity bill. BSES Rajdhani bills say “BSES Rajdhani Power Limited” or “BRPL.” BSES Yamuna bills say “BSES Yamuna Power Limited” or “BYPL.” TPDDL bills say “Tata Power Delhi Distribution Limited” or “TPDDL.” If you’re unsure, call the number on your bill — they’ll confirm your DISCOM.
How long does PM Suryaghar take in Delhi from application to subsidy?
Total timeline is 65–100 days: DISCOM feasibility 12–20 days, installation 1–3 days, inspection and meter change 12–25 days, and subsidy DBT within 30 days of commissioning. Adding RWA approval for apartments extends this by 2–6 weeks. Clean documents and an experienced installer bring the total closer to 65 days.
Can I apply for PM Suryaghar in Delhi if my electricity bill is in my father’s name?
The application must be made by the registered electricity consumer (the person named on the bill). If your father is the registered consumer, he must file the application. The bank account for DBT must also be in his name. You can assist with the process, but the application must be in the account holder’s name.
What is the DERC net metering settlement rate in Delhi?
The DERC feed-in tariff (for annual export credit settlement) is set periodically. As of 2025, the rate for remaining annual credits was approximately ₹3.00–₹3.50/kWh. Current rates for 2026 should be confirmed with your DISCOM or on the DERC website at derc.gov.in. Monthly net metering credits within the billing cycle are applied at import tariff rates.
Does Delhi state give any extra subsidy for solar besides PM Suryaghar?
The Government of Delhi has announced solar incentives in the past (including a state subsidy of ₹2,000/kW in earlier years), but as of 2026, PM Suryaghar’s ₹78,000 central subsidy is the primary available scheme. Check the Delhi government’s energy department website or Delhi Solar Portal for current state-level announcements.
What happens if my BSES solar application is rejected?
If BSES Rajdhani or BSES Yamuna rejects your application, the portal notifies you with a reason code. Common reasons: wrong consumer category, oversized system vs. contracted load, non-empanelled vendor, or document mismatch. See the PM Suryaghar rejection reasons guide for fixes. Correct the issue and reapply — no penalty for reapplication.
Can I install solar on a DDA or government flat in Delhi?
Yes, with additional steps. DDA flat owners have individual roof rights in most configurations. You’ll need NOC from your RWA or housing society, confirmation that the roof structure supports panel loading, and a clear wiring path to your flat’s main board. Many DDA colonies in Rohini, Dwarka, and Vasant Kunj have active solar groups — connecting with them can speed up Society approval.
