10kW Solar System Price in India 2026 (With Subsidy)

What does a 10 kW solar system cost in India in 2026?

A 10 kW grid-connected solar system in India works out to roughly ₹5.5-7 lakh installed, including GST, scaled from published per-kW anchors of ₹55,000-70,000/kW. The PM Surya Ghar central subsidy is fixed at ₹78,000 — it stops growing beyond 3 kW — so your out-of-pocket cost after the CFA is about ₹4.7-6.2 lakh.

TL;DR: Market quotes for 10 kW run about ₹5.5-7 lakh including GST, using the same published per-kW anchors as our 1-5 kW price guides. The central PM Surya Ghar subsidy is ₹78,000 (₹85,800 in special-category states) no matter how much capacity you add above 3 kW, with state top-ups capped at 3-5 kW. A 10 kW plant generates about 1,200-1,450 units a month in North India, needs roughly 90-100 sq m of shadow-free roof and about 17-19 panels, and pays back in roughly 5.5-7 years for a home consuming 1,300-1,400 units a month. Homes and housing societies qualify for the CFA; a shop on a commercial connection does not.

What you will actually be quoted for 10 kW

The ₹78,000 CFA is computed on a benchmark cost, but the quote you pay follows the market. Three published per-kW anchors bracket the realistic range — the same anchors our 5 kW, 3 kW and 1 kW price guides use:

So a realistic installed quote for 10 kW is roughly ₹5.5-7 lakh including GST, depending on module brand, structure height, cabling runs and city. On GST: solar modules and devices carry 5% GST since 22 September 2025, and a full home-system quote blends that with other components, so treat the per-kW anchors as the practical guide. After the ₹78,000 central subsidy, out-of-pocket cost is roughly ₹4.7-6.2 lakh — before any state top-up. Our home solar price guide covers the whole 1-10 kW range in one table.

Subsidy on a 10 kW system

The central CFA is paid on a benchmark cost MNRE fixed at launch: ₹50,000/kW for the first 2 kW and ₹45,000/kW for the third, with no additional CFA beyond 3 kW — so the notional benchmark stops at ₹2,35,000 and the CFA stops at ₹78,000 (MNRE guidelines). In special-category states and UTs (J&K, Himachal, Uttarakhand and others) the ceiling is 10% higher at ₹85,800.

Every state cap binds below 10 kW, so support on a 10 kW system is identical to support on a 3-5 kW system. Mechanics differ — Delhi and UP route their share through the national portal as DBT, Haryana's assistance is credited against electricity bills over time — and all of them, with government sources, are in our state top-up guide.

What a 10 kW system generates and saves

A 10 kW plant in North India typically generates about 1,200-1,450 units a month averaged over the year (roughly 120-145 units per kW) — the city-wise spread is in our units-per-kW guide.

Worked example, with the assumptions stated: a large home consuming about 1,400 units/month (three or more ACs, EV charging at home, a work-from-home office), a 10 kW plant generating about 1,350 units/month, generation fully offset against grid draws. At about ₹5.4/unit — the CREST tariff value our other price guides use; use your own slab rate — monthly savings are roughly 1,350 x ₹5.4 ≈ ₹7,300/month, or about ₹87,500 a year. Against a net investment of ₹4.7-6.2 lakh (quote minus the ₹78,000 CFA), simple payback works out to roughly 5.5-7 years, leaving 18-19 years of essentially free generation over the 25-year plant life.

One caution: if your consumption is well below 1,300 units a month, a 10 kW plant will export a large share of its generation, and surplus export is settled at DISCOM rates far below the retail tariff — our state-wise surplus export rate guide shows how low those rates are. A 10 kW plant pays back fastest when the home actually uses most of its output.

Roof area and equipment for a 10 kW plant

• Roof area: about 90-100 sq m of shadow-free space (the MNRE rule of thumb is roughly 10 sq m per kW) — our roof area guide has the arithmetic per kW and per MW.
• Panels: about 17-19 modules of 540-575 Wp each.
• Inverter and connection: at 10 kW, most homes need a three-phase connection, and some DISCOMs cap residential net-metering capacity below 10 kW — check your state's cap before ordering. Our net metering policy guide and the Delhi BSES/TPDDL net metering guide cover the approval flow.
• Financing: if you would rather not pay the net cost upfront, home solar loans under the scheme's blended rate (repo plus 0.50%) are explained in our PM Surya Ghar loan guide.

Home or shop: who should buy 10 kW

Ten kilowatts suits two very different buyers:

• Large homes and villas with 1,200-1,500-unit bills — multiple ACs, EV charging, heavy kitchen and laundry loads. These qualify for the full CFA and any state top-up.
• Small shops, clinics and offices with similar consumption. A commercial connection gets no PM Surya Ghar subsidy — the scheme is restricted to residential consumers and resident welfare associations/group housing societies. A small business still gains from tariff savings, accelerated depreciation and, where conditions are met, GST input tax credit; our commercial solar subsidy guide explains what applies instead. Larger commercial roofs belong in the C&I lane — our Faridabad industrial solar team handles 100 kW-plus plants.

Frequently Asked Questions

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

About ₹5.5-7 lakh installed including GST, based on published per-kW anchors of ₹55,000-70,000/kW. After the ₹78,000 central subsidy, the out-of-pocket cost is roughly ₹4.7-6.2 lakh. Actual quotes vary with module brand, structure and city.

What subsidy do I get on a 10 kW solar system?

The PM Surya Ghar central CFA is ₹78,000 — the scheme ceiling, identical for every system above 3 kW (₹85,800 in special-category states). State top-ups also cap at 3-5 kW: Delhi takes combined support to ₹1.56 lakh, Haryana adds ₹97,500 via bill credits, UP ₹1.08 lakh and Rajasthan ₹95,000.

How many units does a 10 kW solar system generate per month?

About 1,200-1,450 units a month averaged over the year in North India (roughly 120-145 units per kW). Seasonal variation is real: expect more in the clear months of February-May and less in monsoon.

How much roof area does a 10 kW solar system need?

Roughly 90-100 sq m of shadow-free roof, on the MNRE rule of thumb of about 10 sq m per kW. Elevated or flush-mounted structures and walkway spacing can add to the footprint.

How many solar panels are needed for a 10 kW system?

About 17-19 modules of 540-575 Wp each. Higher-wattage modules reduce the count and the roof footprint.

Is a 10 kW solar system allowed for a home?

Usually yes, but two checks matter: your DISCOM's residential net-metering capacity cap (some states cap residential systems below 10 kW) and the need for a three-phase connection at this size. Both are handled during the net metering application — our policy guide explains the framework.

Can a shop claim the PM Surya Ghar subsidy on a 10 kW system?

No. The CFA is restricted to residential consumers and resident welfare associations/group housing societies. A shop on a commercial connection pays the full installed cost and recovers the investment through tariff savings and tax benefits instead — our commercial subsidy guide explains the alternatives.
