High quality and trusted solar installation for you

Get quote Research Solar





Shalimar Bagh is one of North-West Delhi's well-established residential neighborhoods and a growing rooftop solar market. Electricity here is supplied by Tata Power Delhi Distribution Limited (TPDDL), and homeowners qualify for both the central PM Surya Ghar: Muft Bijli Yojana subsidy and the Delhi state top-up subsidy, together worth up to ₹1,08,000 on a 3 kW residential system.

VaySolar helps Shalimar Bagh residents compare trusted panel brands, size systems accurately for local roof profiles, complete subsidy paperwork correctly for TPDDL's jurisdiction, and get net metering approved without delays.



Quick facts for Shalimar Bagh, North-West Delhi

  • DISCOM: Tata Power Delhi Distribution Limited (TPDDL) — covers North and North-West Delhi, including Shalimar Bagh, Rohini, and Pitampura
  • Regulator: Delhi Electricity Regulatory Commission (DERC)
  • Total subsidy (3 kW+): up to ₹1,08,000 (₹78,000 central + ₹30,000 Delhi state)
  • Net metering: TPDDL-managed, applied for online via the Delhi Solar Portal / PM Surya Ghar National Portal
  • Panel requirement: must be ALMM-listed (Approved List of Models and Manufacturers) to qualify for subsidy



Electricity provider and DISCOM in Shalimar Bagh

Shalimar Bagh falls under the Tata Power Delhi Distribution Limited (TPDDL) (TPDDL) distribution area, which serves North and North-West Delhi, including Shalimar Bagh, Rohini, and Pitampura. This matters for solar installation because:

  • Net metering applications for Shalimar Bagh must be filed with TPDDL, not the other Delhi DISCOMs — applications routed to the wrong DISCOM are rejected outright
  • TPDDL consumer numbers are typically 9-10 digit numbers, with the bill header reading "Tata Power-DDL" — you'll need this from a recent electricity bill for both the subsidy application and net metering request
  • System approvals, meter installation, and bi-directional metering are all coordinated through TPDDL's technical team

VaySolar handles TPDDL coordination end-to-end so homeowners don't have to track approvals themselves.

Why prices vary

Final pricing depends on panel wattage (Topcon/mono PERC vs standard), inverter brand, mounting structure for your specific roof (flat RCC vs sloped/Asbestos), and cabling distance. Get a firm, itemized quote rather than comparing headline ₹/kW numbers alone.

PM Surya Ghar subsidy process for Delhi residents

Under the PM Surya Ghar: Muft Bijli Yojana, the central government subsidy is structured as:

  • ₹30,000 per kW for the first 2 kW
  • ₹18,000 per kW for the third kW
  • Capped at ₹78,000 for systems of 3 kW or above

The Delhi government's state top-up, introduced under the Delhi Solar Policy 2023, adds up to ₹30,000 for systems of 3 kW and above — bringing the combined subsidy to ₹1,08,000.

Step-by-step subsidy application

  1. Register on the PM Surya Ghar National Portal and the Delhi Solar Portal with your TPDDL consumer number
  2. Get a feasibility assessment and system sizing done for your roof
  3. Select an ALMM-approved (Indian-manufactured) panel and a DISCOM-empanelled installer
  4. Installer completes the installation and submits net metering documents to TPDDL
  5. TPDDL conducts an inspection and installs the bi-directional meter
  6. Subsidy is disbursed directly to your bank account after commissioning is confirmed on the portal

Eligibility conditions

  • You must be the legal owner of the roof
  • The system must be grid-tied and use ALMM-listed panels
  • You must not have previously received a subsidy for a system up to 3 kW
  • Only rooftop systems registered against a residential TPDDL connection qualify for the residential subsidy slab

VaySolar manages steps 1–6 on your behalf, including document preparation and TPDDL follow-ups.

Net metering process with TPDDL

Net metering allows excess solar power generated during the day to be exported to the TPDDL grid and credited against your consumption. The process for Shalimar Bagh residents:

  1. Net metering application filed alongside (or after) the PM Surya Ghar registration, using your TPDDL account
  2. TPDDL reviews the application and schedules a site inspection
  3. A bi-directional meter is installed, replacing or supplementing the existing meter
  4. Export/import readings begin reflecting on your monthly TPDDL bill, with excess units carried forward or settled per DERC net metering regulations

Typical TPDDL turnaround for net metering approval is a few weeks from a complete application — incomplete documentation is the most common cause of delay, which is why VaySolar pre-checks paperwork before submission.

Rooftop solar generation potential in Shalimar Bagh

  • Up to 20% return over 25 years with zero bills
  • ₹1,08,000 combined subsidy (central + Delhi state) on 3 kW+ systems
  • 1600+ units/year from 100 sq. ft. roof area at Shalimar Bagh's latitude

At Shalimar Bagh's location (~28.7157°N), rooftop systems typically generate 4–4.5 units per kW per day on average across the year, factoring in Delhi's seasonal haze and monsoon months. A well-sited 3 kW system can offset a large share of a typical North-West Delhi household's monthly electricity bill. Near Shalimar Bagh's residential blocks near the ring road, rooftop orientation and shading from neighboring structures should be checked during the feasibility survey.

How much subsidy can I get in Delhi in 2026?

Up to ₹78,000 from the central PM Surya Ghar Muft Bijli Yojana, plus up to ₹30,000 from the Delhi government's state top-up under the Delhi Solar Policy 2023 — a combined maximum of ₹1,08,000 for systems of 3 kW or above.

How does net metering work with TPDDL?

Excess solar power exported to the grid is recorded on a bi-directional meter installed by TPDDL after a site inspection. Export and import units appear on your monthly bill, and net billing follows DERC's net metering regulations.

How much electricity can I generate with solar in Shalimar Bagh?

100 sq ft of solar panels typically generates 800–1,400 units per year in Delhi, with Shalimar Bagh's location supporting roughly 4–4.5 units per kW per day on average.

What components are needed to install solar?

Solar PV modules, mounting structure, inverter, junction box, data logger, cables and switches. A battery is optional for backup during outages.

How do I evaluate solar vendors in Delhi?

Compare system price, warranties on panels and inverter, generation guarantees, after-sales service coverage in your area, and verified customer feedback on system performance — price alone should never be the deciding factor.

Do I need Indian-manufactured panels to claim the subsidy?

Yes. Subsidy eligibility under PM Surya Ghar requires ALMM-listed (Approved List of Models and Manufacturers), Indian-manufactured panels, along with DISCOM approvals completed before commissioning.
