1. Delhi Rooftop Solar Pricing & Subsidy Matrix (2026)
Under the combined framework of the central PM Surya Ghar Muft Bijli Yojana and the Delhi Solar Policy, residential consumers receive an upfront Central Financial Assistance (CFA) subsidy plus a direct 5-year Generation-Based Incentive (GBI) credited to their monthly power bills.
| System Size | Gross Turnkey Cost | Central CFA Subsidy | Net Consumer Cost | Delhi GBI Earnings (5 Yrs) | Estimated Payback |
|---|---|---|---|---|---|
| 1 kW | ₹60,000 – ₹70,000 | ₹30,000 | ₹30,000 – ₹40,000 | ₹21,600 (₹3.00/unit) | 2.5 Years |
| 2 kW | ₹1,15,000 – ₹1,30,000 | ₹60,000 | ₹55,000 – ₹70,000 | ₹43,200 (₹3.00/unit) | 2.6 Years |
| 3 kW (Most Popular) | ₹1,65,000 – ₹1,85,000 | ₹78,000 | ₹87,000 – ₹1,07,000 | ₹64,800 (₹3.00/unit) | 2.8 Years |
| 5 kW | ₹2,60,000 – ₹2,90,000 | ₹78,000 (Capped) | ₹1,82,000 – ₹2,12,000 | ₹72,000 (₹2.00/unit) | 3.2 Years |
| 10 kW | ₹4,80,000 – ₹5,40,000 | ₹78,000 (Capped) | ₹4,02,000 – ₹4,62,000 | ₹1,44,000 (₹2.00/unit) | 3.4 Years |
2. Delhi Generation-Based Incentive (GBI): How It Works
Delhi is the only union territory in India where the government actively pays you cash for every unit of solar power you generate, regardless of whether you consume it at home or feed it to the grid.
- Systems up to 3 kW: Receive ₹3.00 per kWh generated for 5 consecutive years from commissioning.
- Systems between 3 kW and 10 kW: Receive ₹2.00 per kWh generated for 5 consecutive years.
- Direct DISCOM Bill Credit: GBI earnings are automatically calculated from your generation meter reading and deducted from your electricity bill every month. If your GBI exceeds your bill, the surplus credit rolls over or is deposited directly to your bank account!
3. DISCOM Jurisdiction & Net Metering Rules in Delhi
Power distribution across the National Capital Territory is managed by three primary distribution companies under Delhi Electricity Regulatory Commission (DERC) regulations:
⚡ BSES Rajdhani (BRPL)
Serves South and West Delhi (Vasant Kunj, Saket, Dwarka, Janakpuri). Offers direct online feasibility approval via the BSES Delhi Solar portal. Net meter installation timeline is 15 to 25 days.
⚡ BSES Yamuna (BYPL)
Serves East and Central Delhi (Laxmi Nagar, Mayur Vihar, Chandni Chowk, Daryaganj). Synchronizes with the PM Surya Ghar national portal with expedited CA number verification.
⚡ Tata Power-DDL (TPDDL)
Serves North and Northwest Delhi (Rohini, Pitampura, Model Town). Known for strict DCR serial number verification and digital smart meter testing within 10 days of physical installation.
4. Virtual Net Metering (VNM) for Group Housing Societies
A key innovation in Delhi is Virtual Net Metering (VNM) and Group Net Metering (GNM). In Cooperative Group Housing Societies (CGHS) and multi-story apartment complexes across Dwarka, Rohini, and Mayur Vihar, individual flat owners cannot mount panels on shared roofs.
Under DERC rules, the society management can install a common solar system on the community rooftop. The total electricity generated is credited proportionately across the individual electricity meters of participating flat owners. This completely eliminates high common-area electricity bills (lifts, water pumps, corridor lighting) and passes direct savings to residents.
