If your monthly electricity bill sits somewhere between 150 and 300 units, a 2kW rooftop system is probably one of the first sizes you’ve been quoted.
And the first question is always the same: what is the 2kW solar system price in India once the subsidy comes off?
This guide gives you the real numbers for 2026: the market price range, exactly how much subsidy a 2kW system gets, what it generates, what it can save, and whether 2kW is the right size for your home or whether you’d be better off with 1kW or 3kW.
Quick Answer: 2kW Solar System Price in 2026
A 2kW on-grid rooftop solar system in India typically costs about ₹1.1 lakh to ₹1.6 lakh before subsidy in 2026, depending on panel brand, inverter, structure and installation scope. Under PM Surya Ghar, a 2kW home system gets a ₹60,000 central subsidy, which brings the effective cost to roughly ₹50,000 to ₹1 lakh. In Tamil Nadu, eligible households can get a further ₹10,000 state top-up.
| Amount | |
| Typical market price, 2kW on-grid (before subsidy) | ₹1.1 lakh – ₹1.6 lakh |
| Central subsidy (PM Surya Ghar, 2kW) | ₹60,000 |
| Effective cost after central subsidy | About ₹50,000 – ₹1 lakh |
| Tamil Nadu state top-up (eligible households) | ₹10,000 more |
The price range is a market range from 2026 installer price guides, not a fixed government rate. Your actual quote depends on your roof, location and the equipment chosen.

The simple formula:
Your cost = installer’s quote − central subsidy (₹60,000) − state top-up (if eligible)
How the 2kW Subsidy Works
PM Surya Ghar: Muft Bijli Yojana pays the central subsidy for residential grid-connected rooftop systems at ₹30,000 per kW up to 2kW. That’s why 2kW is a sweet spot: you get the full ₹30,000 per kW on every kilowatt.
| System size | Central subsidy | Subsidy per kW |
| 1kW | ₹30,000 | ₹30,000 |
| 2kW | ₹60,000 | ₹30,000 |
| 3kW and above | ₹78,000 (maximum) | ₹26,000 at 3kW, falling as size grows |
Above 2kW, the extra capacity earns only ₹18,000 per kW, and the total is capped at ₹78,000 from 3kW upwards.
Conditions you must meet
- A residential electricity connection in your name
- A grid-connected (on-grid) system
- DCR panels, made with Indian solar cells
- Installation by a vendor registered on the PM Surya Ghar portal for your DISCOM area
- A bank account correctly linked for direct benefit transfer (DBT)
The subsidy is credited to your bank account after the system is commissioned and the net meter is installed. You pay the installer the full price first, unless you take a loan.
Tamil Nadu state top-up
The Tamil Nadu government has announced an additional state subsidy of ₹5,000, ₹10,000 and ₹22,000 for 1kW, 2kW and 3kW systems (G.O. (Ms) No. 102, dated 19 September 2026). It applies to households that registered on the PM Surya Ghar portal on or after 5 August 2026, and is paid by DBT. A 2kW home in Tamil Nadu could therefore receive ₹70,000 in total support.
Check the current conditions in our Tamil Nadu solar subsidy guide before you rely on it.
What Makes Up the Price of a 2kW System?
Two quotes for “2kW” can differ by ₹40,000 or more. Here’s where that difference comes from:
| Component | What to check | Why it changes the price |
| Solar panels (about 2kWp) | DCR or not, TOPCon or Mono PERC, brand | DCR panels cost more than non-DCR panels, but they’re required for the subsidy |
| Inverter (2kW on-grid) | Brand, warranty, monitoring app | Better-supported brands with longer warranties cost more |
| Mounting structure | Galvanised steel or aluminium, height | Elevated structures and coastal corrosion protection add cost |
| Cables and protection | DC/AC cables, isolators, surge protection | Proper protection is a safety requirement, not an optional extra |
| Earthing and lightning arrester | Number of earth pits | Often left out of cheap quotes |
| Installation and approvals | DISCOM application, net meter process | Some quotes exclude paperwork or meter charges |
GST on solar modules is 5%. Ask whether the quoted price includes GST, and whether DISCOM meter charges are included or extra.
Why DCR matters for price: non-DCR panels are cheaper, but a system built with them doesn’t qualify for the PM Surya Ghar subsidy. For a 2kW home system, the ₹60,000 subsidy is almost always worth far more than the saving on non-DCR panels.
Our DCR vs non-DCR panel guide explains the difference.
How Much Does a 2kW System Generate?
According to MNRE’s consumer FAQ, a 1kWp rooftop system can generate 4 to 5.5 units on a clear sunny day. So a 2kW system can produce roughly 8 to 11 units on a clear day.
Real output across the year is lower than the clear-day figure, because of:
- cloudy and rainy monsoon days
- dust on the panels
- partial shading from tanks, walls or trees
- heat, which slightly reduces panel output
- the direction and tilt of your roof
Practical rule: ask your installer for an expected yearly generation figure for your roof, based on its direction and shading. That number, not the clear-day figure, should drive your savings estimate.
Always verify subsidy amounts and vendor registration on the official portal, pmsuryaghar.gov.in. The scheme’s implementation period under MNRE’s guidelines runs until 31 March 2027.
Roof space needed
MNRE’s FAQ says 1kW generally needs about 10 square metres of shadow-free area, so plan for roughly 20 square metres for a 2kW system. Higher-wattage modern panels can need a little less, but the space must be free of shade for most of the day.
How Much Can a 2kW System Save?
Savings depend on how many units the system generates, how many of them you use or offset, and your tariff. Here’s a worked example. All figures are assumptions chosen to show the method, not a promise:
| Assumption | Value |
| Average generation across the year | 8 units per day |
| Yearly generation | 8 × 365 = 2,920 units |
| Value of each unit offset (your tariff) | ₹6 per unit (assumed) |
| Estimated yearly saving | 2,920 × ₹6 = ₹17,520 |
| Effective cost after ₹60,000 subsidy | ₹70,000 (example) |
| Simple payback | ₹70,000 ÷ ₹17,520 ≈ 4 years |
To estimate your own payback, swap in your installer’s yearly generation figure, your actual tariff and your quote.
Why your state’s metering rules matter
What happens to the units you export changes your savings:
- Tamil Nadu (TANGEDCO), domestic net metering: exported units are set off against the units you use, and any surplus carries forward until 31 March. Surplus still unused on 31 March lapses without payment. So don’t oversize: a 2kW system should match your yearly consumption.
- Kerala (KSEB): surplus is banked month to month with a 2% monthly banking charge. Any balance left at the end of the financial year is paid at a much lower rate than your tariff (₹2.79 per unit for new solar consumers).
In both states, the best return comes from using as much solar power as possible yourself, for example by running the washing machine, water pump or iron during the day.
Who Should Buy a 2kW Solar System?
The PM Surya Ghar guidance links system size to monthly consumption:
| Average monthly consumption | Suitable rooftop capacity |
| 0–150 units | 1–2kW |
| 150–300 units | 2–3kW |
| Above 300 units | Above 3kW |
A 2kW system is a good fit if:
- your bills average roughly 150–250 units a month across the year
- you have about 20 square metres of shade-free roof
- you want the full ₹30,000-per-kW subsidy, with a lower upfront cost than 3kW
- your sanctioned load allows a 2kW system (your DISCOM checks this)
- Consider 1kW if you use under about 120 units a month, have limited roof space, or want the lowest possible upfront cost.
- Consider 3kW if your bills are regularly near or above 300 units, you’re adding an AC or EV, or you want the maximum ₹78,000 subsidy. Total subsidy is higher at 3kW, though the subsidy per kW is lower. For larger homes, see our 5kW solar system price guide.
When 2kW isn’t the right choice
- Frequent long power cuts: a standard on-grid 2kW system shuts down during an outage. You’d need a hybrid system with a battery, which costs considerably more.
- Shaded roof: if trees or buildings shade the roof for much of the day, the generation estimate drops and the payback stretches.
- Your local transformer is full: DISCOMs limit how much solar can connect to each transformer. In Kerala, for example, KSERC caps it at 90% of the transformer’s capacity. Check this before you pay an advance. Our KSEB solar feasibility check guide explains how.
On-Grid vs Hybrid vs Off-Grid 2kW: Price Difference
| 2kW system type | Typical 2026 price (before subsidy) | PM Surya Ghar subsidy | Works in a power cut? |
| On-grid | ₹1.1 – ₹1.6 lakh | Yes, ₹60,000 (if conditions are met) | No |
| Hybrid (with battery) | Roughly ₹1.8 – ₹2.8 lakh or more | Check eligibility on the official portal | Yes, for backed-up loads |
| Off-grid | Roughly ₹2 – ₹3.2 lakh or more | Not under the rooftop scheme | Yes |
Ranges are indicative market figures from 2026 installer price guides. Battery type and size drive most of the difference for hybrid and off-grid systems.
For most homes with a reliable grid supply, on-grid gives the lowest cost per unit and the fastest payback.
Paying for It: Upfront or Loan
- Upfront payment: you pay the full price to the installer, then receive the subsidy in your bank account after commissioning.
- Solar loan: PM Surya Ghar solar loans can be applied for through the government’s JanSamarth portal, and many banks also accept applications at branches. Compare interest rates, processing fees and the total amount repayable. Our guide to choosing a solar loan bank compares the main options.
Steps to Get a 2kW System with Subsidy
- Check your bills for 12 months and confirm that 2kW suits your use.
- Register on pmsuryaghar.gov.in with your electricity consumer number and apply for rooftop solar.
- Wait for DISCOM feasibility approval, which checks your connection and the local transformer’s capacity.
- Choose a registered vendor for your area, and get a written, itemised quote naming the panel and inverter models.
- Installation by the vendor, who then uploads the installation details.
- DISCOM inspection and net meter installation.
- Commissioning, then submit your bank details for the subsidy.
You can track each stage in your consumer login. Our guide on how to check your PM Surya Ghar application status explains what each status means.
Five Questions to Ask Before You Accept a 2kW Quote
A low headline price can hide missing items. Before you sign, ask:
- Are the panels DCR, and which exact model and wattage are they? Without DCR panels, you lose the ₹60,000 subsidy.
- What yearly generation do you expect from my roof? A good installer gives a figure based on your roof’s direction and shading, not just the clear-day maximum.
- Is everything included? Check the structure, earthing, lightning arrester, cabling, DISCOM application and net meter process, and GST.
- Are you registered as a PM Surya Ghar vendor for my DISCOM area? Confirm this yourself on the official portal.
- What warranties do I get, and who handles service? You should receive the panel and inverter manufacturers’ warranties, plus the installer’s own workmanship warranty and a local service contact.
If two quotes differ a lot in price, these five answers usually explain why.
Conclusion
- In 2026, a 2kW on-grid solar system typically costs ₹1.1-₹1.6 lakh before subsidy and about ₹50,000-₹1 lakh after the ₹60,000 PM Surya Ghar subsidy, with an extra ₹10,000 for eligible Tamil Nadu homes.
- It suits households using roughly 150-250 units a month with about 20 square metres of shade-free roof, and it earns the full ₹30,000 subsidy on every kilowatt.
- Get a written quote with named equipment, check your expected yearly generation, and verify vendor registration on the official portal before you sign.

Frequently Asked Questions about 2kW solar system
-
What is the price of a 2kW solar system after subsidy?
With a typical 2026 market price of ₹1.1–₹1.6 lakh and the ₹60,000 central subsidy, the effective cost is roughly ₹50,000 to ₹1 lakh. Eligible Tamil Nadu households can get ₹10,000 more from the state top-up.
-
How many units does a 2kW solar system produce per day?
On a clear sunny day, about 8 to 11 units, based on MNRE’s figure of 4–5.5 units per kW. The yearly average is lower because of cloudy days, dust and shading.
-
Can a 2kW solar system run an AC?
It can supply part of an AC’s daytime power, but a 2kW on-grid system won’t run an AC during a power cut, and heavy AC use usually needs a larger system. If AC use pushes your bills above 300 units a month, look at 3kW or more.
-
Is 2kW enough for a 2BHK home?
Often, yes, if your monthly use is around 150–250 units. Size by your actual bills rather than by the number of rooms.
-
Does a 2kW system need a battery?
No. An on-grid 2kW system works without a battery and is the type covered by the subsidy. Add a battery (hybrid) only if you need backup during power cuts.
-
How long does a 2kW solar system last?
MNRE’s FAQ gives solar modules a standard life of over 25 years. Inverters usually need replacing earlier, so check their warranty.
