Before you choose 4 kW
- The home subsidy is ₹78,000, the same as 3 kW, so the fourth kilowatt is paid for in full. Check that 3 kW really falls short before stepping up.
- Check the sanctioned load on your bill before applying. If it is under 4 kW, PSPCL load enhancement comes first.
- Not sure? Enter your bill in the calculator. It recommends the smallest system that does the job.

4 kW system: questions we are asked
What is the price of a 4 kW solar system in Punjab?
A on-grid 4 kW system costs ₹2,14,000 – 2,35,000 installed. After the PM Surya Ghar subsidy of ₹78,000, a home pays ₹1,36,000 – 1,57,000. A hybrid system with a battery costs ₹3,17,000 – 3,48,000 and is subsidised the same way; an off-grid system costs ₹2,05,000 – 2,26,000 and 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 4 kW system?
₹78,000 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. The subsidy is capped at ₹78,000 from 3 kW upwards. 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 4 kW solar system generate in Punjab?
About 408 units a month, or 4,896 a year, at the conservative figure we use for estimates. Output is higher from March to June and lower in December and January and on hazy days.
How much roof space does a 4 kW system need?
About 400 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 4 kW system?
At least 4 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 4 kW the right size for my home?
For a general-category home, a 4 kW system brings net use under the 300-unit line for homes using roughly 557 to 658 units a month, which takes the bill to zero. Enter your own bill in the calculator on our website to check.
