10kW Solar System Price in India with Subsidy (2026): The Complete Cost Breakdown

Quick answer: In 2026, a standard on-grid 10kW rooftop solar system in India costs about ₹5.6–6.4 lakh installed. After the PM Surya Ghar central subsidy — which caps at ₹78,000 for any system of 3kW and above — your effective cost is roughly ₹4.8–5.6 lakh. It generates around 1,200–1,500 units a month, enough for a large home with heavy AC and EV-charging load, and typically pays for itself in about 4–5 years, then produces essentially free power for 20+ more. All figures are indicative; final pricing follows a free site survey.

10kW is the upper end of what most DISCOMs sanction as a residential rooftop connection — the size for a large independent house, a 5–6 BHK home, or a family running multiple ACs, a borewell motor and an EV charger together. It's also the size where some homeowners start wondering whether they've crossed into commercial territory. This guide breaks down the 2026 cost, what the subsidy actually pays at this size, and how to tell if 10kW is right for your home — or whether your usage is better served by our commercial/MSME solar offering instead.

Where the money goes: component-wise breakdown

Component	Share of cost	What to look for
Solar panels (≈18–24 modules)	~45–55%	Tier-1 mono PERC / TOPCon, 25+ year performance warranty
Inverter (10kW, often three-phase)	~15–18%	Reputed brand, 5–10 year warranty, app-based monitoring, correct phase for your connection
Mounting structure	~8–12%	Hot-dip galvanised, wind-rated for your region — more structure needed at this size
Cables, earthing, protection (BOS)	~8–12%	Copper DC cables sized for longer runs, proper earthing kit, surge protection
Installation, net metering & paperwork	~10–15%	DISCOM liaison for a higher sanctioned load, net meter, commissioning included

Per-kW cost usually keeps falling as system size grows — a 10kW system typically costs less per kW than a 5kW one, since mobilisation, liaison and design overheads spread across more capacity. Be cautious of quotes well below this range: at 10kW the gap usually hides in a single-phase inverter forced onto a three-phase load, thinner structure not rated for the extra panel weight and wind load, or "DISCOM liaison extra." Get the phase and sanctioned-load requirement confirmed in writing before you sign.

The subsidy on 10kW: still ₹78,000, and a sanctioned-load check to make first

Under PM Surya Ghar: Muft Bijli Yojana, the subsidy structure is the same regardless of how large your residential system gets past 3kW:

₹30,000 per kW for the first 2 kW
₹18,000 for the third kW
kW 4 through 10: no additional subsidy — the cap is ₹78,000 for any residential system of 3kW and above

So a 10kW system gets the same central subsidy as a 3kW one — on a percentage basis it covers roughly 12–14% of the installed cost, versus ~40% at 3kW. The subsidy still lands directly in your bank account after commissioning; a proper installer never asks you to sign it over. Before committing to 10kW, two things are worth checking with your DISCOM: whether your existing electricity connection's sanctioned load can support a 10kW system (some residential connections need to be upgraded, often to three-phase), and whether your roof can genuinely take ~800–1,000 sq ft of shadow-free array without shading losses. Greentek handles both the DISCOM paperwork and the shadow analysis as part of the free site survey. For the full application walkthrough, see our step-by-step PM Surya Ghar guide.

What does a 10kW system actually generate?

Across most of India, expect roughly 40–50 units per day on average from a 10kW array — around 1,200–1,500 units a month. As with smaller systems, generation peaks in summer and dips through the monsoon, and sun-rich states like Telangana, Rajasthan and Gujarat sit toward the higher end of the range. With net metering, a 10kW system can offset a household consuming 1,000–1,300 units a month — the kind of usage pattern you see with multiple ACs, a swimming pool pump, or daily EV charging.

Is 10kW the right size, or should you look at commercial/MSME solar?

Choose 10kW residential: a large independent house or villa, multiple ACs running most of the day, an EV on home charging, and a roof that can take ~900 sq ft of array without shading.
Consider our commercial/MSME solar instead: if the connection is (or could be) a commercial/industrial one, or you're powering a shop, small factory or office rather than a home — different tariff structure, different depreciation benefits, and no PM Surya Ghar residential subsidy ceiling to work around. See our dedicated guide to solar for MSMEs.
Choose 5kW instead: if your monthly consumption is under ~700–800 units — see our 5kW price breakdown.

The reliable way to size a system at this level is 6–12 months of electricity bills, your DISCOM's sanctioned load, and a proper roof/shadow survey — all part of a free Greentek site survey. You can also get a quick estimate with our solar savings calculator.

Payback: the roughly 4-year math

Take a typical case: effective cost ₹5.2 lakh after subsidy, generation of 1,350 units/month, and a tariff of ₹8/unit. That's roughly ₹10,800/month (~₹1.3 lakh/year) of bill avoided — recovering your investment in about 4 years. Everything after that is essentially free electricity for the remaining 20+ years of panel life. Your actual numbers depend on tariff slab, consumption pattern and site conditions — treat any installer's "guaranteed savings" claim with caution; savings are always subject to site assessment.

How to judge a 10kW quote — a 6-point checklist

Panel make and technology — Tier-1 mono PERC/TOPCon with a written 25+ year performance warranty.
Inverter phase and brand — confirm single- or three-phase matches your actual connection, 5-year minimum warranty, app-based monitoring.
Structure specification — hot-dip galvanised steel, wind-speed rated for the extra panel count; ask for the drawing.
Sanctioned load and DISCOM liaison — confirm your connection can support 10kW, and that liaison/upgrade work is priced in, not "extra."
Subsidy handling — the installer should file your PM Surya Ghar application; the subsidy lands in your account.
Who stands behind it — years in business, service network, and real installed references. Greentek has been in renewable energy since 1997, manufactures solar equipment in-house, and has delivered projects from 10 KW to 1 GW+ — including work at AIIMS campuses, IITs and IIMs.

Frequently asked questions

What is the price of a 10kW solar system in India in 2026?

About ₹5.6–6.4 lakh installed for a standard on-grid system (indicative mid-2026 range), and roughly ₹4.8–5.6 lakh effective after the ₹78,000 PM Surya Ghar subsidy. Final pricing depends on components, phase requirement, roof and location.

How much subsidy do I get on a 10kW system?

The central subsidy caps at ₹78,000 (reached at 3kW), so a 10kW system gets the same ₹78,000 — credited directly to your bank account after commissioning and net metering.

Do I need a three-phase electricity connection for 10kW?

Often, yes — many DISCOMs require a three-phase connection for residential loads above roughly 7–8kW. Confirm your sanctioned load and phase with your installer before finalising a 10kW quote; upgrading a connection, if needed, should be scoped and priced upfront.

How many units per month will it generate?

Around 1,200–1,500 units a month in most Indian cities (40–50 units/day), varying by season, city and shading.

What's the payback period?

Most homes recover the post-subsidy cost in about 4–5 years, against a system life of 25+ years. Payback depends on your tariff and consumption — savings subject to site assessment.

Is 10kW residential or commercial?

10kW is generally the top end of residential rooftop solar under PM Surya Ghar, suited to large homes with heavy consumption. If the connection is commercial/industrial, or you're powering a business rather than a home, our solar for MSMEs guide covers the different subsidy, depreciation and financing picture that applies instead.
