Solar Energy in Kerala: Complete 2026 State Guide
Kerala, despite heavy monsoons (June–August), has a strong solar policy backed by KSEB and ANERT. Its ₹15,000/kW additional state subsidy makes the net cost of a 3 kW system in Kerala among the lowest in India.
Solar Potential in Kerala
Kerala receives approximately 4.8 peak sun hours per day on average. A 3 kW rooftop solar system in Kerala generates approximately 4,468 units per year and can save ₹2,387/month on your electricity bill at the current KSEB Ltd tariff of ₹6.50/unit.
