Solar Energy in Asansol: Complete 2026 Guide
Asansol is West Bengal's second largest city and a coal-mining heritage belt. As coal mines age, the region is transitioning toward solar — both residential and agri-solar under KUSUM are gaining traction. With electricity tariffs charged by WBSEDCL at ₹7.50/unit and rising every year, switching to rooftop solar is now the single best financial decision a Asansol household can make in 2026.
Solar Potential: How Much Can You Generate in Asansol?
Asansol receives approximately 4.5 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 1,387 units of electricity per year.
For a typical 3 kW system — the most popular size for a 2–3 BHK home — you can expect:
- ~11.4 units per day on average (higher in summer, lower in monsoon)
- 4,161 units per year
- ₹2,565/month savings on your WBSEDCL electricity bill
- Payback period: ~3.3 years after PM Surya Ghar subsidy
