KSEB Solar Net Metering — Export Rate

Under net metering, KSEB consumers with rooftop solar systems can export surplus electricity to the grid and receive credit. KSEB's export/banking rate varies by category under KSERC's new Renewable Energy Regulations (effective from January 2026): approximately ₹3.08/unit for existing prosumers and ₹2.79/unit for new prosumers on annual banked-energy settlement, an APPC of around ₹3.26/unit for banked energy, and a real-time net-metering credit rate cited as high as ₹3.56/unit in some KSEB communications. Because this changed recently and multiple rates apply depending on your prosumer category and settlement choice, verify your exact applicable rate directly with KSEB before relying on any single figure.

Net metering settlement for KSEB is annual banked-energy settlement (typically each September), under KSERC's 2025 Renewable Energy Regulations effective January 2026, as per KSERC (Kerala State Electricity Regulatory Commission) regulations.

How Solar Saves Money Under KSEB Tariffs

For a household consuming 300–400 units per month in the KSEB area, a 3 kW solar system can offset 300–360 units per month (25 kWh/day average). At current KSEB tariffs, this can save a meaningful portion of the electricity bill each month, depending on which consumption slab your usage falls into and your generation profile.
