Solar Calculator Punjab 2026

Rooftop solar in Punjab

Punjab is served by a single state utility, Punjab State Power Corporation Limited (PSPCL), which handles both distribution and your net-metering connection. Under the state rooftop framework, domestic consumers can set up net metering up to their sanctioned load, commonly to 10 kW, with exported surplus credited against imported units and settled periodically. Because PSPCL revises its commercial circulars from time to time, confirm the current net-metering terms and any banking limits before you apply.

Tariffs, free power and savings

Punjab runs a 300-unit free electricity scheme for domestic households, so many families pay little or nothing on modest usage. Above that threshold, or for larger homes, marginal grid power sits near 7 per unit, and that is where a rooftop system earns its keep. A well-sited array in the Punjab plains yields about 4.5 units per kW per day, roughly 1,640 units per kW each year. Use our solar savings calculator to turn your bill into an estimated size.

Agricultural context

Punjab also supplies free power to farm tube-well connections, a long-standing subsidy that shapes the state power economy. For irrigation loads, feeder-level or off-grid solar under schemes like PM-KUSUM can matter more than a home rooftop; explore pump sizing in the KUSUM solar pump calculator.

How PM Surya Ghar applies

The national PM Surya Ghar: Muft Bijli Yojana pays 30,000 per kW for the first 2 kW and an extra 18,000 for the 3rd kW, capping the central subsidy at 78,000 for systems of 3 kW and above, with net metering to 10 kW. The money reaches you by DBT after commissioning and inspection, and the balance can be met with a collateral-free loan near 7 percent - model repayments in the solar loan EMI calculator.

A worked example

Take a 3 kW system in Ludhiana. At 4.5 units per kW per day it may generate about 4,900 units a year. For a household consuming beyond the free slab at around 7 per unit, that offsets close to 34,000 annually. With central support of 78,000 trimming a gross cost near 1.7 lakh to under 1 lakh net, payback often lands in roughly three years. Treat these as planning figures - weather, shading and how much you exceed the free allowance all change the outcome. For a battery-free layout see the on-grid solar calculator, or start from a national baseline with the India solar calculator.

Frequently asked questions

No separate per-kW state capital subsidy is confirmed active for Punjab in 2025-26; the main benefit is the central PM Surya Ghar amount of up to 78,000 for 3 kW and above. Always check with PSPCL for the latest schemes before you rely on any figure.

If your usage stays within the 300-unit free slab you may already pay little, so solar saves most when your consumption runs above the free limit at around 7 per unit. Larger homes and higher bills see the fastest payback.

PSPCL is the single distribution utility for the state and handles net metering up to your sanctioned load, commonly to 10 kW for domestic connections. Apply through the national portal linked to PSPCL.

At about 4.5 units per kW per day a 3 kW system may generate near 4,900 units. For consumption above the free slab at roughly 7 per unit that is close to 34,000 a year, though weather, shading and usage change the result.
