Punjab's domestic electricity tariff is ₹7/kWh and the net-metering buyback rate is ₹2.5/kWh, via PSPCL. Here's what that means for a home going solar. Data updated January 2026.
A 3 kWp on-grid system in Punjab generates roughly 4,440 units per year at local irradiance. At ₹7/kWh, if you use most of it yourself, that's around ₹31,080 saved annually. After the ₹78,000 PM Surya Ghar subsidy, payback lands near 3.8 years — before counting any export income.

Your distribution company is PSPCL. 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 ₹2.5/kWh — lower than the ₹7 you pay, which is why self-consuming your generation is always worth more than exporting it.
With one of India's higher tariffs at ₹7/kWh, Punjab offers some of the fastest solar payback in the country. Every unit you generate offsets an expensive grid unit. Combined with 5.2 peak sun hours a day, the numbers work well. Use the solar calculator for Punjab 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 Punjab (₹7/kWh) compares, or see all state electricity tariffs.
