Solar Energy in Varanasi: Complete 2026 Guide
Varanasi, the spiritual capital of India, has installed solar at several ghats under the Smart City Mission. PM Modi's parliamentary constituency has been a showcase for solar India's push into tier-2 cities. With electricity tariffs charged by PUVVNL at ₹6.50/unit and rising every year, switching to rooftop solar is now the single best financial decision a Varanasi household can make in 2026.
Solar Potential: How Much Can You Generate in Varanasi?
Varanasi 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
- ₹2,457/month savings on your PUVVNL electricity bill
- Payback period: ~3.5 years after PM Surya Ghar subsidy
