10 kW Solar System Price in India (2026), With Subsidy
A 10 kW rooftop solar system costs roughly ₹5–6.5 lakh before subsidy. The central PM Surya Ghar subsidy is ₹78,000, which brings the cost to roughly ₹4.22–5.72 lakh in most states. These are indicative ranges to sanity-check a quote against — not a quote.
Indicative installed cost
₹5–6.5 lakh
Central subsidy
₹78,000
Cost after subsidy
₹4.22–5.72 lakh
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 10 kW System Involves
- Panels: about 19 modules of around 545 W (the exact count follows the wattage you are quoted).
- Roof: about 800 sq ft of shadow-free area, at our rule of thumb of 80 sq ft per kW.
- Generation: about 40 units a day, roughly 1,200 units a month or 14,600 units a year. Output varies with state, shading and cleaning.
- Bill offset: at ₹7 per unit that is about ₹8,400 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 | ₹78,000 | ₹4,22,000 – ₹5,72,000 |
| Bihar | ₹98,000₹78,000 central + ₹20,000 state | ₹4,02,000 – ₹5,52,000 |
| Uttar Pradesh | ₹1,08,000₹78,000 central + ₹30,000 state | ₹3,92,000 – ₹5,42,000 |
| DelhiGeneration incentive not included; a reported zero-upfront scheme may apply — see the Delhi page | ₹1,08,000₹78,000 central + ₹30,000 state | ₹3,92,000 – ₹5,42,000 |
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 | ₹87,600 | 4.8 – 6.5 years |
| ₹8 per unit | ₹1,16,800 | 3.6 – 4.9 years |
| ₹10 per unit | ₹1,46,000 | 2.9 – 3.9 years |
Is 10 kW Right for You?
A 10 kW system suits a large home, a small shop or workshop, or a small institution. At this size the economics are driven by your electricity savings, because the central subsidy is fixed at ₹78,000.
Larger users should also look at the commercial options on our MSME page, where accelerated depreciation and different tariffs change the maths.
Watch out for
- Beyond 3 kW each extra kW earns no central subsidy, so the subsidy is a small share of the total cost at 10 kW.
- Systems this size usually need a larger sanctioned load and may involve a three-phase connection. Confirm with your DISCOM before you pay a deposit.
- Roof area becomes the constraint: about 800 square feet of shadow-free space, plus structural checks for wind loading.
- Commercial and industrial tariffs differ from residential tariffs. If this is a business connection, use the MSME page and calculators rather than the residential subsidy rules.
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.

The central PM Surya Ghar subsidy is ₹78,000, so the cost after subsidy is roughly ₹4.22–5.72 lakh 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 10 kW solar system?
The central subsidy is ₹78,000 for 10 kW, which covers about 12%–16% 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.
Does a 10 kW system get the full subsidy?
It gets the same maximum central subsidy as a 3 kW system, ₹78,000, not more. A verified state top-up can add to this where it applies.
How much roof area does a 10 kW system need?
About 800 square feet of shadow-free space by our rule of thumb of 80 square feet per kW, plus clearance for maintenance access.
