Get quote Research Solar





Tilak Nagar is one of West Delhi's well-established residential neighborhoods and a growing rooftop solar market. Electricity here is supplied by BSES Rajdhani Power Limited (BRPL), 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 Tilak Nagar residents compare trusted panel brands, size systems accurately for local roof profiles, complete subsidy paperwork correctly for BRPL's jurisdiction, and get net metering approved without delays.



Quick facts for Tilak Nagar, West Delhi

  • DISCOM: BSES Rajdhani Power Limited (BRPL) — covers South and West Delhi, including Tilak Nagar, Janakpuri, and Vikas Puri
  • Regulator: Delhi Electricity Regulatory Commission (DERC)
  • Total subsidy (3 kW+): up to ₹1,08,000 (₹78,000 central + ₹30,000 Delhi state)
  • Net metering: BRPL-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 Tilak Nagar

Tilak Nagar falls under the BSES Rajdhani Power Limited (BRPL) (BRPL) distribution area, which serves South and West Delhi, including Tilak Nagar, Janakpuri, and Vikas Puri. This matters for solar installation because:

  • Net metering applications for Tilak Nagar must be filed with BRPL, not the other Delhi DISCOMs — applications routed to the wrong DISCOM are rejected outright
  • BRPL consumer numbers start with "CA-" followed by 11 digits, or appear as a plain 11-digit number — 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 BRPL's technical team

VaySolar handles BRPL 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 BRPL 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 BRPL
  5. BRPL 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 BRPL connection qualify for the residential subsidy slab

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

Net metering process with BRPL

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

  1. Net metering application filed alongside (or after) the PM Surya Ghar registration, using your BRPL account
  2. BRPL 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 BRPL bill, with excess units carried forward or settled per DERC net metering regulations

Typical BRPL 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 Tilak Nagar

  • 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 Tilak Nagar's latitude

At Tilak Nagar's location (~28.6414°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 West Delhi household's monthly electricity bill. Near Tilak Nagar's residential blocks near Subhash Nagar, rooftop orientation and shading from neighboring structures should be checked during the feasibility survey.

How does net metering work with BRPL?

Excess solar power exported to the grid is recorded on a bi-directional meter installed by BRPL 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 Tilak Nagar?

100 sq ft of solar panels typically generates 800–1,400 units per year in Delhi, with Tilak Nagar'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.
