Before you choose 3 kW
- The subsidy stops rising at 3 kW. A 5 kW or 10 kW home system gets the same ₹78,000, so every kW above 3 is paid for in full.
- Check your units before settling on 3 kW. Under Punjab’s free-units rules, a smaller hybrid system may already take your bill to zero, and the calculator will show you if it does.
- Not sure? Enter your bill in the calculator. It recommends the smallest system that does the job.

3 kW system: questions we are asked
What is the price of a 3 kW solar system in Punjab?
A on-grid 3 kW system costs ₹1,80,000 – 1,98,000 installed. After the PM Surya Ghar subsidy of ₹78,000, a home pays ₹1,02,000 – 1,20,000. A hybrid system with a battery costs ₹2,78,000 and is subsidised the same way; an off-grid system costs ₹2,40,000 – 2,70,000 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 3 kW system?
₹78,000 for a home, whether the system is on-grid or hybrid — RSK'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 3 kW solar system generate in Punjab?
About 306 units a month, or 3,672 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 3 kW system need?
About 300 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 3 kW system?
At least 3 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 3 kW the right size for my home?
For a general-category home, a 3 kW system brings net use under the 300-unit line for homes using roughly 455 to 556 units a month, which takes the bill to zero. Enter your own bill in the calculator on our website to check.
