What does a 2 kW solar system cost in India in 2026
A 2 kW grid-connected home solar system works out to about ₹1,00,000 at the MNRE benchmark cost used to compute the PM Surya Ghar subsidy (₹50,000 per kW for the first 2 kW), while real installed quotes in 2026 land around ₹1.1–1.4 lakh including GST based on published per-kW cost anchors. The central subsidy on 2 kW is a fixed ₹60,000, so the out-of-pocket cost is roughly ₹50,000–80,000 — less in states that add their own top-up.
TL;DR: MNRE benchmark ₹1.0 lakh (ex-GST); market quotes roughly ₹1.1–1.4 lakh including GST; central subsidy ₹60,000 fixed at 2 kW; net cost about ₹50,000–80,000 before state top-ups; generation around 3,000–3,200 units a year in North India; payback typically 3–5 years; the PM Surya Ghar scheme runs until 31 March 2027.

How the PM Surya Ghar subsidy works on 2 kW
The PM Surya Ghar central financial assistance (CFA) is not paid on your invoice — it is computed from a benchmark cost fixed by MNRE, effective 13 February 2024. At 2 kW, the maths is simple:
| System size | Benchmark cost | Central CFA | Where it comes from |
|---|---|---|---|
| 1 kW | ₹50,000 | ₹30,000 | ₹30,000/kW for the first 2 kW |
| 2 kW | ₹1,00,000 | ₹60,000 | ₹30,000/kW × 2 kW |
| 3 kW | ₹1,45,000 | ₹78,000 | ₹30,000 × 2 + ₹18,000 for the third kW |
| Above 3 kW | ₹45,000 per extra kW | ₹78,000 (ceiling) | No additional CFA beyond 3 kW |
Source: MNRE's PM Surya Ghar guidelines, which fix the benchmark at ₹50,000/kW for the first 2 kW and ₹45,000 for the additional kW, with CFA of ₹30,000/kW (first 2 kW) and ₹18,000/kW (third kW). MNRE restated the benchmark history — down from ₹75,000/kWp in 2016 to ₹50,000/kWp in 2024 — in a Lok Sabha answer in August 2026.
Two cautions that matter at 2 kW:
- The benchmark is notional. It exists to compute the subsidy formula, not to cap or guarantee your quote. Actual prices depend on module technology, mounting height, structure work, cabling length and city logistics.
- GST is separate from the benchmark. Solar modules and devices carry 5% GST since 22 September 2025, and a turnkey residential EPC contract works out to roughly 8.9% effective GST under the 70:30 component split — electricity itself stays exempt. Ask the vendor for the module vs EPC-services split in writing so you can see what you are paying GST on.
MNRE's own sizing table, published with the CFA structure, ties monthly consumption to capacity: households using 150–300 units a month suit a 2–3 kW plant (PM Surya Ghar CFA structure). A 2 kW system is the lower end of that band.
What you will actually be quoted for 2 kW
Per-kW price anchors published in 2026 let you sanity-check quotes:
| Anchor | Implied per-kW rate | Source |
|---|---|---|
| CREST's Chandigarh example: ₹1.8 lakh total for 3 kWp incl GST | ₹60,000/kW | Times of India, February 2026 |
| Haryana energy minister: typical 1 kW residential plant ≈ ₹55,000 | ₹55,000/kW | Times of India, June 2026 |
| Central Bank of India loan scheme assumption | ₹70,000/kW | Central Bank of India |
Scaled to 2 kW, those anchors give a quote band of roughly ₹1.1–1.4 lakh including GST — and small systems typically price at the higher per-kW end because fixed costs (structure, metering, labour) spread over fewer kilowatts. A 2 kW turnkey quote should include panels, inverter, mounting structure, DC/AC cabling, the net-metering meter and application support, and installation labour.
A quote far below the ₹1.0 lakh benchmark for 2 kW deserves scrutiny rather than celebration: check module brand and wattage, inverter warranty, and whether the quoted price actually covers the DISCOM meter and net-metering application.
What a 2 kW system generates and saves
In Delhi-NCR and Haryana, a well-installed rooftop plant generates about 1,500–1,600 units per kW per year (MNRE's normative planning figure is 4–5.5 units/kW/day on clear sunny days) — the city-wise spread is in our units-per-kW guide for North Indian cities. A 2 kW plant therefore generates roughly 3,000–3,200 units a year, or 250–270 units a month, averaged over the year.
Worked example, with the assumptions stated:
- Net investment ₹60,000 (mid-range: ₹1.2 lakh gross minus the ₹60,000 CFA)
- Generation 2,900 units/year (conservative, below the 3,000–3,200 band)
- Value of offset units ₹5.4/unit (the tariff value used in CREST's published example)
Annual savings: 2,900 × ₹5.4 = ₹15,660. Payback: ₹60,000 ÷ ₹15,660 ≈ 3.8 years; at the top of the quote band (₹80,000 net) it stretches to about 5.1 years. Homes on higher effective domestic tariffs recover faster; homes on low slabs slower. Our payback and ROI guide covers how tariffs, consumption pattern and net-metering settlement change the answer.
Roof needed: roughly 12–15 sq m of shadow-free area (CREST's 3 kW example used 18–22 sq m) and about 4–5 modules of 500–575 Wp each.
State top-ups on a 2 kW system
Several governments add money on top of the central ₹60,000:
| State | State top-up on 2 kW | Total support |
|---|---|---|
| Delhi | ₹52,000 (₹26,000/kW) | ₹1,12,000 |
| Haryana | ₹39,000 (₹19,500/kWp, bill-credited instalments) | ₹99,000 |
| Uttar Pradesh | ₹30,000 (₹15,000/kW, up to 2 kW) | ₹90,000 |
| Rajasthan | ₹17,000 (flat) | ₹77,000 |
| Punjab, Himachal, Uttarakhand | none currently | ₹60,000 |
Every amount, with its government source and payment mechanics, is in our PM Surya Ghar state top-up guide. In Delhi, the combined central-plus-state support of ₹1.12 lakh matches the entire 2 kW benchmark cost — which is why Delhi's subsidy structure for 1–5 kW systems and the free-units scheme for solar homes make a well-specified 2 kW plant close to free for many households. Quotes above benchmark still cost you the difference.
Who should buy a 2 kW system
- Households using 150–250 units a month — the MNRE sizing table puts this band at 2–3 kW.
- Homes where the roof or the budget rules out 3 kW. The CFA jumps only ₹18,000 between 2 kW and 3 kW, so if consumption is rising — a second AC, an EV — check the 3 kW economics before settling on 2 kW.
- Homes on a tight budget: at ₹50,000–80,000 net, 2 kW is the cheapest entry into net-metered rooftop solar.
How to apply and claim the subsidy
The flow is the same across states: register on the national portal with your electricity account number, choose a registered vendor, install, clear the DISCOM inspection, and receive the CFA by direct bank transfer after commissioning. For subsidised systems the modules must be domestic-content (DCR) types, so confirm this with your vendor. The average CFA release runs about 15 days after the redemption request (MNRE, Lok Sabha, August 2026).
Financing: collateral-free loans at repo + 0.50% (5.75% p.a. at the last PIB update, 10-year tenure) are available for systems up to 3 kW — see our solar loan guide for homeowners. The scheme is approved until 31 March 2027 (MNRE guidelines); the installation date, not just registration, needs to fit inside the window.
2 kW vs 3 kW vs 5 kW
| 2 kW | 3 kW | 5 kW | |
|---|---|---|---|
| Benchmark cost | ₹1,00,000 | ₹1,45,000 | ₹2,35,000 |
| Central CFA | ₹60,000 | ₹78,000 | ₹78,000 |
| Generation (North India) | ~3,000–3,200 units/yr | ~4,600–4,800 units/yr | ~7,700–8,000 units/yr |
| Roof area | 12–15 sq m | 18–22 sq m | 30–36 sq m |
The 5 kW figures use the ₹45,000/additional-kW benchmark beyond 3 kW (₹1,45,000 + ₹45,000 × 2). Full 5 kW economics are in our 5 kW price guide, and the home solar price guide for 2026 covers the whole 1–10 kW ladder.

Frequently Asked Questions
What is the price of a 2 kW solar system after subsidy?
About ₹50,000–80,000 out of pocket in 2026: the ₹60,000 central subsidy is deducted from a gross price that sits between the ₹1.0 lakh MNRE benchmark and typical market quotes of ₹1.1–1.4 lakh including GST. State top-ups reduce it further — to roughly ₹8,000–28,000 net in Delhi.
How much subsidy will I get on 2 kW under PM Surya Ghar?
₹60,000 — ₹30,000 per kW for the first 2 kW, paid by direct bank transfer after installation and DISCOM inspection. State top-ups are additional: Delhi ₹52,000, Haryana ₹39,000 (bill-credited), UP ₹30,000, Rajasthan ₹17,000.
Is 2 kW enough for my home?
If your consumption is 150–250 units a month, yes. Below 150 units, 1 kW may suffice; above 300 units, MNRE's sizing table points to 3 kW or larger.
How many solar panels are needed for a 2 kW system?
About 4–5 modules of 500–575 Wp each, occupying roughly 12–15 sq m of shadow-free roof.
How much does a 2 kW solar system generate per month?
Around 250–270 units a month averaged over the year in Delhi-NCR and Haryana, peaking near 320–340 units in summer months and dipping to about 160–180 in December–January.
Is the 2 kW subsidy the same in every state?
The central CFA of ₹60,000 is identical everywhere except special-category states (J&K, Himachal, Uttarakhand and others), where the per-kW CFA is ₹33,000 — so 2 kW gets ₹66,000 there. State top-ups differ sharply — see the state table above.
What happens after 31 March 2027?
MNRE has approved PM Surya Ghar for implementation until 31 March 2027. Applications must be installed and commissioned inside the window to carry the CFA; anything beyond depends on the scheme's extension, which has not been announced.
