Residential rooftop solar in Jaipur typically pays back in 4-5 years and runs for 25 years. The economics work because:
- JVVNL tariff: ₹5.80-₹11.40 per unit (slab-based)
- Solar generation: 360-750 units/month for 3-5 kW
- PM Surya Ghar + RREC subsidy cuts upfront cost by ₹95,000
- Lifetime savings on a 3 kW system: ₹17-22 lakh
