Goa's domestic electricity tariff is ₹3.9/kWh and the net-metering buyback rate is ₹2.2/kWh, via Goa Electricity Dept.. Here's what that means for a home going solar. Data updated January 2026.
A 3 kWp on-grid system in Goa generates roughly 4,272 units per year at local irradiance. At ₹3.9/kWh, if you use most of it yourself, that's around ₹16,661 saved annually. After the ₹78,000 PM Surya Ghar subsidy, payback lands near 7.0 years — before counting any export income.

Your distribution company is Goa Electricity Dept.. 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 ₹2.2/kWh — lower than the ₹3.9 you pay, which is why self-consuming your generation is always worth more than exporting it.
At ₹3.9/kWh, Goa's tariff is on the lower side, so payback is slower than high-tariff states. Solar still works, but maximising self-consumption matters more here. Combined with 5 peak sun hours a day, the numbers work well. Use the solar panel cost calculator for Goa 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 Goa (₹3.9/kWh) compares, or see all state electricity tariffs.
