Solar Energy in Delhi: Complete 2026 Guide
Delhi has India's highest domestic solar subsidy ecosystem — combining PM Surya Ghar central subsidy, Delhi's ₹2/unit GBI, and India's best net metering policy. A 3 kW system in Delhi can generate ₹8,000+ in annual savings. With electricity tariffs charged by BSES Rajdhani at ₹8.50/unit and rising every year, switching to rooftop solar is now the single best financial decision a Delhi household can make in 2026.
Solar Potential: How Much Can You Generate in Delhi?
Delhi receives approximately 5.0 peak sun hours per day (based on MNRE solar radiation data for this region). This means every 1 kW of rooftop solar installed here generates about 1,533 units of electricity per year.
For a typical 3 kW system — the most popular size for a 2–3 BHK home — you can expect:
- ~12.6 units per day on average (higher in summer, lower in monsoon)
- 4,599 units per year
- ₹3,213/month savings on your BSES Rajdhani electricity bill
- Payback period: ~2.6 years after PM Surya Ghar subsidy
PM Surya Ghar Subsidy for Delhi Residents
Residents of Delhi in Delhi are fully eligible for the PM Surya Ghar Muft Bijli Yojana. The central government provides a Direct Benefit Transfer (DBT) subsidy directly to your bank account:
- Up to 2 kW system: ₹30,000/kW (total ₹60,000 for 2 kW)
- 2 kW to 3 kW: ₹18,000/kW for the additional capacity
- Above 3 kW: No additional central subsidy — but net metering earnings continue
- Maximum central subsidy: ₹78,000 for a 3 kW system
State subsidy note: Delhi Government offers a generation-based incentive (GBI) of ₹2/unit for solar power exported to the grid, over and above PM Surya Ghar. Apply via DISCOM or Delhi Solar Portal.
