1 kW solar system price in Punjab
Homes just over the 300-unit line, where a small system is enough to bring net use back under it. RSK Solar Energy does not install on-grid systems this small, so this size comes as hybrid (with a battery) or off-grid. About 135 units a month from 100 sq ft of roof.
| Hybrid system, installed | ₹2,05,000 to 2,25,000 |
|---|---|
| PM Surya Ghar subsidy, home | − ₹30,000 |
| Your cost after subsidy | ₹1,75,000 to 1,95,000 |
| Generation | 135 units a month |
| Roof area | 100 sq ft |
| Minimum sanctioned load | 1 kW |
| Takes a home to a zero bill if it uses | 301 to 385 units a month |
You pay the full price first. The subsidy is credited to your bank account 30 to 45 days after the PSPCL inspection.

Before you choose 1 kW
- Hybrid at 1 kW still receives the PM Surya Ghar subsidy, the same as on-grid, because RSK Solar Energy’s hybrid installs are grid-tied and net-metered and stay connected to PSPCL.
- Off-grid does not receive the subsidy, at any size, because it is not net-metered.
- A 1 kW system needs at least 1 kW of sanctioned load. Most homes already have more.
- Not sure? Enter your bill in the calculator. It recommends the smallest system that does the job.

We plan on about 135 units a month from each kW of panels in Punjab, averaged over the year. With TOPCon panels, output can reach up to about 180 units per kW in the sunniest months. These are estimates: real output depends on the roof’s direction and shade, dust, the weather and the panels and inverter used. Zero-bill figures assume a general-category home and that PSPCL applies the 300 free units to net units.

1 kW system: questions we are asked
What is the price of a 1 kW solar system in Punjab?
A hybrid 1 kW system costs ₹2,05,000 to 2,25,000 installed. After the PM Surya Ghar subsidy of ₹30,000, a home pays ₹1,75,000 to 1,95,000. RSK Solar Energy does not install on-grid systems this small; 3 kW is the smallest on-grid system we offer. An off-grid system at 1 kW costs ₹47,000 to 51,000, but does not qualify for the subsidy. The final price depends on the roof, the mounting structure, cable runs and the panel model.
How much subsidy do I get on a 1 kW system?
₹30,000 for a home, whether the system is on-grid or hybrid. RSK Solar Energy's hybrid systems are grid-tied and net-metered, so they qualify the same way on-grid does. It is paid into your bank account 30 to 45 days after PSPCL inspects the system, not deducted from the price. Off-grid systems, businesses and industry do not get it; housing societies get ₹18,000 per kW for common facilities.
How many units does a 1 kW solar system generate in Punjab?
About 135 units in an average month, with standard panels. Output is higher from March to June and lower in December and January and on hazy days. With TOPCon panels, a 1 kW system can reach up to about 180 units in the sunniest months. These are estimates.
How much roof space does a 1 kW system need?
About 100 sq ft of shade-free roof, at roughly 100 sq ft per kW including access space between rows.
What sanctioned load do I need for a 1 kW system?
At least 1 kW. In Punjab a rooftop system cannot exceed your sanctioned load, which is printed on your electricity bill. If yours is lower, apply to PSPCL for load enhancement before applying for the subsidy.
Is 1 kW the right size for my home?
For a general-category home, a 1 kW system brings net use under the 300-unit line for homes using roughly 301 to 385 units a month, which takes the bill to zero. Enter your own bill in the calculator on our website to check.
