Solar Energy in Assam: Complete 2026 State Guide
Assam's heavy monsoon (June–September) reduces solar generation during those months, but the state's additional ₹15,000 subsidy and rising tariffs make solar viable with a 6–7 year payback in Guwahati.
Solar Potential in Assam
Assam receives approximately 4.2 peak sun hours per day on average. A 3 kW rooftop solar system in Assam generates approximately 3,909 units per year and can save ₹1,992/month on your electricity bill at the current APDCL tariff of ₹6.20/unit.
Estimated payback period: ~4.3 years after PM Surya Ghar subsidy. After payback, you get 20+ years of virtually free electricity.
