3 kW solar system price in India
Indicatively ₹1.60 – ₹2.00 lakh turnkey before subsidy, and roughly ₹82,000 – ₹1.22 lakh after PM Surya Ghar. Here is what drives that number, what the system generates, and whether this size actually fits your home.
Indicative assessment only. Final system size, generation, savings, approvals and price are subject to a bill analysis, site survey, structural check and shadow assessment.
Does 3 kW suit your home?
A 3–4 BHK home with two or more air conditioners, or a house with a borewell pump.
It fits a monthly bill of roughly ₹2,500 – ₹4,000 a month. Payback is typically 4–5 years after subsidy.
What to know before you buy
3 kW is where the central subsidy caps out at ₹78,000. Every kW beyond this is fully self-funded, so it is the natural stopping point for most homes unless consumption genuinely justifies more.
The subsidy on a 3 kW system
Under PM Surya Ghar: Muft Bijli Yojana, a 3 kW system attracts up to ₹78,000.
- Paid into your bank account after installation and inspection — not deducted from the price up front.
- Residential grid-connected systems only, installed by a registered vendor.
- Some states add their own subsidy on top of the central amount.
Subsidy rates are set by government order and change. Confirm the current position on the official PM Surya Ghar portal before you commit. Structure above last checked 2026-08-26.
How the installation works
- 1
Bill and roof check
We look at twelve months of bills and your usable, shadow-free roof area. Those two together decide the size — not a guess from your floor plan.
- 2
Portal registration
PM Surya Ghar registration and the DISCOM application, filed for you. The subsidy depends on this being done correctly and by a registered vendor.
- 3
Design and approval
Layout, structure specification and the DISCOM technical feasibility approval before anything is ordered.
- 4
Installation
Structure, modules, inverter, cabling and earthing. Typically two to four days on site for a home system.
- 5
Net meter and inspection
Bi-directional meter installation, DISCOM inspection and grid synchronisation.
- 6
Subsidy disbursal
Once inspection clears, the subsidy claim goes through the portal and is credited to your bank account.

3 kW solar — common questions
What is the 3 kW solar system price in India?
Indicatively ₹1.60 – ₹2.00 lakh turnkey before subsidy — modules, inverter, mounting structure, cabling, earthing, installation and the DISCOM approvals. Under PM Surya Ghar a 3 kW system attracts up to ₹78,000, bringing the net cost to roughly ₹82,000 – ₹1.22 lakh. This is a range, not a quote: roof type, structure height and the cable run to your meter all move it.
How much roof does a 3 kW system need?
Plan for ~300 sq.ft shadow-free. That means genuinely shadow-free — a water tank, a parapet or a neighbouring wall that shades part of the array for a few hours a day costs real generation, and it is the most common reason a system underperforms its quote.
How much will a 3 kW system generate?
Around ~330–390 units a month, varying with your region and season. Rajasthan and Gujarat sit at the higher end; the East and North-East lower. Winter fog in the northern belt cuts output for a few weeks each year.
Is a 3 kW system right for my home?
It suits a home with a bill around ₹2,500 – ₹4,000 a month. A 3–4 BHK home with two or more air conditioners, or a house with a borewell pump. Size follows your consumption, not your roof area — a system bigger than your usage exports surplus you may not be paid much for.
What is the payback on a 3 kW system?
Typically 4–5 years after subsidy, depending on your tariff and how much of your consumption falls in daylight hours. 3 kW is where the central subsidy caps out at ₹78,000. Every kW beyond this is fully self-funded, so it is the natural stopping point for most homes unless consumption genuinely justifies more.
