Assam's domestic electricity tariff is ₹5.2/kWh and the net-metering buyback rate is ₹2.8/kWh, via APDCL. Here's what that means for a home going solar. Data updated January 2026.
A 3 kWp on-grid system in Assam generates roughly 4,272 units per year at local irradiance. At ₹5.2/kWh, if you use most of it yourself, that's around ₹22,214 saved annually. After the ₹78,000 PM Surya Ghar subsidy, payback lands near 5.3 years — before counting any export income.

Your distribution company is APDCL. To go solar with net metering, you apply for feasibility approval, install through a registered vendor, and get a bi-directional meter. Surplus units you export earn ₹2.8/kWh — lower than the ₹5.2 you pay, which is why self-consuming your generation is always worth more than exporting it.
At ₹5.2/kWh, Assam sits in the middle band — solar pays back solidly, especially if you consume most of your generation during the day. Combined with 5 peak sun hours a day, the numbers work well. Use the solar panel cost calculator for Assam to size a system against your own bill.
Tariffs and buyback rates change at state borders, which is why payback can differ a lot between neighbours. Here is how Assam (₹5.2/kWh) compares, or see all state electricity tariffs.
