Rooftop Solar in Delhi NCR
Delhi has India's fastest solar payback — 3-3.5 years. Highest residential tariffs in India + ₹78K PM-Surya Ghar + Delhi GBI ₹2/unit subsidy + 3 DISCOMs supporting net metering = unbeatable economics.
Why Delhi Has India's Best Solar Economics
Despite less direct sunshine than Tamil Nadu, Delhi beats every state on solar payback period. Three reasons:
Highest Tariff in India
BSES residential tariff: ₹3-8.50/unit (slab-based). Above 1,200 units/month: ₹8.50/unit. Solar offsets the expensive top slab — fastest savings impact.
Stacking Subsidy
PM-Surya Ghar ₹78K + Delhi GBI ₹2/unit (3 years, 1500 units/year cap). Combined ~₹95K+ effective subsidy on 3kW system.
3 Competing DISCOMs
BSES Rajdhani, BSES Yamuna, Tata Power-DDL all support net metering. Competition keeps approval times fast (7-10 days vs 30+ days in other states).
Delhi DISCOM Net Metering — Choose Your Provider
Delhi is unique: three different DISCOMs serve different zones. Each has slightly different processes:
| DISCOM | Zone | Net Metering | Approval Time |
|---|---|---|---|
| BSES Rajdhani (BRPL) | South & West Delhi | Up to 10 kW residential | 7-12 days |
| BSES Yamuna (BYPL) | Central & East Delhi | Up to 10 kW residential | 10-15 days |
| Tata Power-DDL | North & NW Delhi | Up to 10 kW residential | 7-10 days (fastest) |
Delhi Solar Subsidy — PM-Surya Ghar + GBI Stacked
Delhi is one of the few states offering stackable subsidies on top of central PM-Surya Ghar:
PM-Surya Ghar (Central)
Up to ₹78,000 for 3kW system. One-time, paid post-installation.
Delhi GBI (State)
₹2 per unit generated, capped at 1,500 units/year, for first 3 years. ~₹4,500/year × 3 = ₹13,500.
Net Metering Savings
Excess generation credits at retail tariff. Most Delhi solar homes pay ₹0-500/month vs ₹3000+ before solar.
| System Size | Cost (Delhi) | PM-Surya Ghar | Delhi GBI (3 yrs) | Net Cost |
|---|---|---|---|---|
| 1 kW | ₹68,000 | ₹30,000 | ~₹4,500 | ₹33,500 |
| 2 kW | ₹1,35,000 | ₹60,000 | ~₹9,000 | ₹66,000 |
| 3 kW (Recommended) | ₹1,95,000 | ₹78,000 | ~₹13,500 | ₹1,03,500 |
| 5 kW | ₹3,25,000 | ₹78,000 | ~₹13,500 | ₹2,33,500 |
