Solar system price in Punjab, with subsidy.

Price by system size, with subsidy

Installed price for a grid-connected rooftop system in Punjab, including structure, wiring, net metering and paperwork. The installed price is what you pay. The PM Surya Ghar subsidy is not deducted from the invoice: it is paid into your bank account later.

The Government of India pays up to ₹78,000 into your account after PSPCL inspection. It comes to you after the system is installed and is not taken off the installed price above.

Generation assumes roughly 1,460 units per kW per year, which is a fair average for Punjab’s irradiance across a full year. Above 10 kW the residential subsidy does not apply. Punjab adds no state subsidy on top of the central one.

Before you buy: the 300 free units question

This is the part most quotations leave out, and it decides the whole thing.

Punjab gives domestic consumers 300 free units a month. If your household sits under that, your electricity bill is already at or near zero, and solar cannot save you money you are not spending. The payback is not long in that case, it is undefined. We would rather say that now than after you have paid for a system.

Rooftop solar is worth buying in Punjab if you:

• regularly cross 300 units a month, particularly with air conditioning through the summer;
• have a commercial or industrial connection, where no free allowance applies and tariffs are higher;
• run an agricultural or mixed-load connection;
• want backup through outages, which needs a battery system such as the SolarYaan All-in-One rather than the grid-connected systems priced above;
• are building now and want the structure done once, correctly, rather than retrofitted later.

It is also worth knowing that this is visible in the national data. Punjab converts applications into commissioned systems better than Haryana, Rajasthan or Gujarat. The installers here do their job. But Punjab files fewer than a seventh of Haryana’s applications. Far fewer households start, and the free-units threshold is the most plausible reason why.

You can check that yourself on our live rooftop solar tracker, which publishes Punjab against every other state, updated daily from the Government of India portal, or on PM Surya Ghar in Punjab for the state alone.

How the subsidy is calculated

PM Surya Ghar pays by slab, not by percentage:

• ₹30,000 per kW for the first 2 kW
• ₹18,000 for the third kW
• capped at ₹78,000, so 3 kW and 10 kW receive the same amount

So 3 kW is the smallest system that collects the full subsidy. Going larger buys you more generation, not more subsidy. The subsidy needs DCR modules. The subsidy explained in full.

What moves the price on a real roof

• Structure. A flat RCC roof is straightforward. An elevated structure over a courtyard, parking or water tank needs more steel and costs more.
• Shading. A neighbouring block or a water tank shading part of the array changes the layout and sometimes the inverter choice.
• Sanctioned load and phase. PSPCL normally sanctions up to your existing load. A single-phase connection limits you; upgrading has its own cost and timeline.
• Cable run. Distance from the array to the meter is real copper.
• Panel and inverter choice. The make and model of each moves the price. The PM Surya Ghar subsidy needs DCR modules, and a system built with other panels cannot claim it. Use a BIS-certified inverter; SolarYaan inverters are.
