Quick answer: With Gujarat’s new state top-up on PM Surya Ghar, a 2 kW rooftop solar system can cost a home about ₹10,000, and a 2.18 kW system about ₹10,810 (10% of the government benchmark; 5% for SC/ST homes). Without the top-up, 2 kW costs ₹1.04–1.16 lakh before the ₹60,000 central subsidy. It applies to systems commissioned from 22 October 2026.
In October 2026 the Gujarat government approved an extra subsidy for small home solar systems, on top of the central PM Surya Ghar subsidy. The state expects to spend about ₹1,000 crore on it and reach more than 3 lakh households. For homes using up to about 300 units a month, it makes solar almost free. This guide explains what a 2 kW or 2.18 kW system costs now, how the two subsidies add up, what it saves, and the conditions you should know before you sign.

2 kW solar system price in Gujarat with the state subsidy
The state scheme works off a benchmark cost: ₹50,000 a kW for the first 2 kW and ₹45,000 a kW above that, up to a total system size of 2.18 kWp. The central subsidy is taken off first, you pay 10% of the benchmark (5% if you’re SC/ST), and the state pays the rest.
| System size | Benchmark cost | Central subsidy | State top-up (general) | You pay (general) | You pay (SC/ST) |
|---|---|---|---|---|---|
| 1 kW | ₹50,000 | ₹30,000 | ₹15,000 | ₹5,000 | ₹2,500 |
| 2 kW | ₹1,00,000 | ₹60,000 | ₹30,000 | ₹10,000 | ₹5,000 |
| 2.18 kW | ₹1,08,100 | ₹63,240 | ₹34,050 | ₹10,810 | ₹5,405 |
Why 2.18 kW? It’s the largest size that still qualifies, and it costs only about ₹810 more than 2 kW for about 22 more units a month. If your roof and load allow it, 2.18 kW is usually the better pick. Anything above 2.18 kWp, including 3 kW, gets the central subsidy only.
2 kW price without the state top-up
If your system doesn’t qualify for the state scheme (for example, it was commissioned before 22 October 2026, or you want a premium brand priced well above the benchmark), the market price applies:
| Item | 2 kW on-grid (DCR panels) | 2.18 kW on-grid |
|---|---|---|
| Installed price | ₹1,04,000 – ₹1,16,000 | ₹1,13,000 – ₹1,26,000 |
| Central subsidy | ₹60,000 | ₹63,240 |
| You pay (central subsidy only) | ₹44,000 – ₹56,000 | ₹50,000 – ₹63,000 |
| Generation | About 240 units a month | About 260 units a month |
| Roof area needed | About 160–200 sq ft | About 180–220 sq ft |
Market quotes sit above the ₹50,000-a-kW benchmark, so ask every vendor in writing what you will pay in total after both subsidies, and whether any amount above the benchmark is charged to you. The detailed DISCOM procedure for the state top-up hadn’t been published as of early November 2026. Our solar panel price list for Gujarat covers every size from 1 kW to 10 kW.
How much will a 2 kW or 2.18 kW system save?
In Gujarat a well-installed plant makes about 4 units per kW a day. Here’s the monthly benefit on a UGVCL, DGVCL, MGVCL or PGVCL home bill:
| Monthly use | Bill before solar | 2 kW benefit | 2.18 kW benefit |
|---|---|---|---|
| 150 units | ₹928 | ₹1,105 | ₹1,154 |
| 200 units | ₹1,258 | ₹1,322 | ₹1,372 |
| 250 units | ₹1,588 | ₹1,508 | ₹1,590 |
| 300 units | ₹1,970 | ₹1,610 | ₹1,736 |
For a home using 250 units a month, a 2.18 kW plant brings the bill down to the ₹25 fixed charge and saves about ₹1,590 a month, roughly ₹19,000 a year. If your share is ₹10,810, the system pays for itself in about seven months, then keeps saving for 25 years. Under GERC’s new 2026 rules, homes keep full net metering set-off; see our net metering guide for Gujarat.
Who should choose 2.18 kW, and who should choose 3 kW?
- Using up to about 300 units a month: take 2.18 kW with the state top-up. You pay a fraction of the cost and use almost all of what it makes.
- Using 350 units or more: a 3 kW system saves more each month, even though you pay ₹72,000–93,000 after the central subsidy. See our 3 kW solar system price guide for the full comparison.
- Expecting your use to grow soon (a new AC, an EV, more family members): think carefully. Under the state scheme you can’t add capacity for three years.
Conditions of the Gujarat state top-up
- Size: total rooftop capacity up to 2.18 kWp on the connection. Larger systems don’t qualify.
- Date: only systems commissioned on or after 22 October 2026.
- Scheme: it’s a top-up on PM Surya Ghar, so the central rules still apply: residential connection in your name, DCR panels, a vendor registered for your DISCOM, and no earlier rooftop subsidy on that connection.
- Payment: by direct benefit transfer to your bank account, through your DISCOM (DGVCL, MGVCL, PGVCL, UGVCL or Torrent Power). GUVNL is the nodal agency.
- Lock-in: no extra rooftop capacity for three years from installation.

How to get a 2 kW system with both subsidies
- Check your last 12 bills. If average use is under about 300 units a month, 2 kW or 2.18 kW fits.
- Register on pmsuryaghar.gov.in with your DISCOM and consumer number, and apply for rooftop solar.
- Choose a registered vendor and get the system size, total price and your final share in writing.
- The vendor installs the plant (usually one day on site) and uploads the details.
- The DISCOM inspects and fits the net meter, and the commissioning report is generated.
- The central subsidy and the state top-up are paid to your bank account.

Frequently asked questions
What is the price of a 2 kW solar system in Gujarat with subsidy?
With the PM Surya Ghar subsidy and Gujarat’s new state top-up, a home pays about 10% of the benchmark cost: about ₹10,000 for 2 kW (₹5,000 for SC/ST homes). Without the state top-up, a 2 kW system costs ₹1.04–1.16 lakh and ₹44,000–56,000 after the ₹60,000 central subsidy (indicative, November 2026).
What is the Gujarat state solar subsidy for 2.18 kW?
For systems up to 2.18 kWp, the state pays the balance of the benchmark cost after the central subsidy and your 10% share. For 2.18 kW the benchmark is ₹1,08,100, the central subsidy ₹63,240, your share ₹10,810 and the state top-up about ₹34,050.
Why is the limit 2.18 kW?
The state set the top-up for total rooftop capacity up to 2.18 kWp. Systems above that, including 3 kW, get only the central PM Surya Ghar subsidy.
From when does the Gujarat state top-up apply?
It applies to rooftop systems commissioned on or after 22 October 2026. Systems commissioned before that date are not covered.
How is the state subsidy paid?
By direct benefit transfer to your bank account through your DISCOM (DGVCL, MGVCL, PGVCL, UGVCL or Torrent Power), with GUVNL as the nodal agency.
Can I increase my system size later?
Not for three years from installation if you take the state top-up. If you expect your electricity use to grow soon, compare it with a 3 kW system first.
How many units does a 2 kW solar system generate in Gujarat?
About 240 units a month, or about 260 units for 2.18 kW, at roughly 4 units per kW a day. Output is higher in summer and lower in the monsoon.
Is 2 kW enough for my home?
A 2 kW or 2.18 kW system suits homes using up to about 300 units a month. Above about 350 units, a 3 kW system saves more each month.
How much roof space does a 2 kW solar system need?
About 160–200 sq ft of shadow-free roof, or 180–220 sq ft for 2.18 kW, for three or four panels.
Do SC/ST households pay less?
Yes. SC/ST households pay 5% of the benchmark cost instead of 10%: about ₹5,000 for 2 kW and ₹5,405 for 2.18 kW. The state top-up covers the difference.
