2 kW Solar System Price in India (2026), With Subsidy
A 2 kW rooftop solar system costs roughly ₹1.1–1.5 lakh before subsidy. The central PM Surya Ghar subsidy is ₹60,000, which brings the cost to roughly ₹50,000–90,000 in most states. These are indicative ranges to sanity-check a quote against — not a quote.
Indicative installed cost
₹1.1–1.5 lakh
Central subsidy
₹60,000
Cost after subsidy
₹50,000–90,000
PM Surya Ghar subsidy window: 31 March 2027
The ₹78,000 central residential subsidy is sanctioned through the end of FY 2026-27 (31 March 2027). Apply and get commissioned well before this date. No extension has been officially notified; MNRE has indicated the one-crore-household target may fall short by March 2027, which makes an extension plausible but not assured — plan around the published date.

What a 2 kW System Involves
- Panels: about 4 modules of around 545 W (the exact count follows the wattage you are quoted).
- Roof: about 160 sq ft of shadow-free area, at our rule of thumb of 80 sq ft per kW.
- Generation: about 8 units a day, roughly 240 units a month or 2,920 units a year. Output varies with state, shading and cleaning.
- Bill offset: at ₹7 per unit that is about ₹1,680 a month of electricity replaced. Use your own tariff in the subsidy calculator.
Cost After Subsidy in Your State
The central subsidy is the same everywhere. Where a state adds a top-up that we have been able to verify, it is included below.
| State | Total subsidy | Cost after subsidy |
|---|---|---|
| Most states (central subsidy only)No documented state top-up on our verified list | ₹60,000 | ₹50,000 – ₹90,000 |
| Bihar | ₹80,000₹60,000 central + ₹20,000 state | ₹30,000 – ₹70,000 |
| Uttar Pradesh | ₹90,000₹60,000 central + ₹30,000 state | ₹20,000 – ₹60,000 |
| DelhiGeneration incentive not included; a reported zero-upfront scheme may apply — see the Delhi page | ₹80,000₹60,000 central + ₹20,000 state | ₹30,000 – ₹70,000 |
Reported, conditional or announced state schemes for Gujarat, Maharashtra, Rajasthan and Tamil Nadu could not be verified as general subsidies, so they are not included. Check the state subsidy page and confirm with your state agency.
Payback at Different Electricity Rates
Payback is the cost after subsidy divided by the yearly bill saving, assuming every unit generated replaces a unit you would have bought. The range runs from the low to the high end of the cost band.
| Your rate | Yearly saving | Payback (central subsidy only) |
|---|---|---|
| ₹6 per unit | ₹17,520 | 2.9 – 5.1 years |
| ₹8 per unit | ₹23,360 | 2.1 – 3.9 years |
| ₹10 per unit | ₹29,200 | 1.7 – 3.1 years |
Is 2 kW Right for You?
A 2 kW system suits a small family home with a moderate bill — several fans and lights, a refrigerator, a washing machine and an air conditioner used some of the day.
It is the last size at which every kW earns the full ₹30,000 central subsidy, which makes the subsidy a large share of the cost.
Watch out for
- The jump from 2 kW to 3 kW earns a smaller extra subsidy (₹18,000 for the third kW), so the third kW costs more out of pocket than the first two did.
- If you expect your consumption to grow — an extra air conditioner, an electric vehicle — it can be cheaper to size up now than to add capacity later.
- Check that your roof has the shadow-free area. A system that is sized on paper but shaded in practice generates well below the estimate.
What Your Quote Should Include
A quote far below the band is usually a thinner specification, not a better deal: our cost benchmarks note that quotes 30–40% below the applicable band typically reflect thinner structure steel, undersized cable or missing protection. Ask for line-by-line detail.
- Module make, model and wattage — and written confirmation of ALMM listing and DCR status for that exact model, because the subsidy needs domestically manufactured modules.
- Inverter make, rating and warranty term, and whether arc-fault (AFCI) protection is included and switched on.
- Mounting structure: steel grade, thickness, galvanising, and the wind speed it is designed for.
- DC and AC cable sizes, earthing and lightning protection, and surge protection — the items that get cut when a quote is cheap.
- Net meter, DISCOM approval and inspection charges, and whether the installer handles the subsidy paperwork.
- Who services the system, for how long, and what the warranty covers in writing.

What is the price of a 2 kW solar system in India with subsidy?
Using our indicative cost band, a 2 kW residential system costs roughly ₹1.1–1.5 lakh before subsidy. The central PM Surya Ghar subsidy is ₹60,000, so the cost after subsidy is roughly ₹50,000–90,000 in states with no verified top-up. Quotes vary with brand, structure and roof, so compare at least three written quotes.
How much subsidy do I get on a 2 kW solar system?
The central subsidy is ₹60,000 for 2 kW, which covers about 40%–55% of the indicative cost. Uttar Pradesh and Delhi add a verified state top-up on top; confirm any state scheme with your state nodal agency. As of October 2026, the central scheme runs to 31 March 2027.
What bill does a 2 kW solar system cover?
At about 4 units per kW per day, a 2 kW system generates roughly 240 units a month. Divide your recent monthly units by 240 to see how much of your consumption it could offset; the calculator shows the rupee value at your own tariff.
How much roof space do I need for 2 kW?
About 160 square feet of shadow-free area, using our rule of thumb of 80 square feet per kW. Water tanks, parapet shadows and nearby buildings reduce usable space.
