Solar Energy in Delhi: Complete 2026 State Guide
Delhi has India's richest solar incentive stack — PM Surya Ghar (₹78,000) + Delhi GBI (₹2/unit × 5 years) + high DISCOM tariff (₹8.50/unit). A Delhi 3 kW system yields ₹7,500–₹9,000/month in savings or credits.
Solar Potential in Delhi
Delhi receives approximately 5.0 peak sun hours per day on average. A 3 kW rooftop solar system in Delhi generates approximately 4,654 units per year and can save ₹3,251/month on your electricity bill at the current BSES Rajdhani tariff of ₹8.50/unit.
Estimated payback period: ~2.6 years after PM Surya Ghar subsidy. After payback, you get 20+ years of virtually free electricity.
