A 3kW rooftop array is the sweet spot for most homes across Faridabad, Palwal and Gurugram — large enough to cover a typical 2-3 BHK household's daytime load, small enough to fit comfortably on an average rooftop. Before you commit, though, you deserve a clear answer to the only question that really matters: what will it cost you after everything is settled? Here is the full picture for 2026.
Sizing Up the Sticker Price
In the South Haryana market, residential solar lands at roughly ₹55,000 to ₹65,000 per kW for a well-built on-grid system. For 3kW, that puts the gross price in the ₹1,65,000 – ₹1,95,000 band before any subsidy.
Here is where that money goes:
| Component | Typical Cost (3kW) | |---|---| | Solar modules (mono PERC / TOPCon) | ₹72,000 – 88,000 | | Grid-tie inverter | ₹28,000 – 40,000 | | Galvanised mounting structure | ₹14,000 – 20,000 | | DC/AC cabling, earthing, SPD, arrestor | ₹13,000 – 18,000 | | Labour & commissioning | ₹14,000 – 18,000 | | Net-meter charges & DHBVN liaison | ₹8,000 – 14,000 | | Gross total | ₹1,65,000 – 1,95,000 |
Where you land in that range depends on module technology, the inverter brand, and how awkward your roof is to mount on. A flat RCC roof in a Faridabad sector home is cheaper to work with than a sloped or multi-level terrace in older Palwal housing.
The One Subsidy That Counts
It is worth being blunt about this, because there is a lot of misinformation floating around: in Haryana, the headline financial support for a home solar system comes from one scheme — the central PM Surya Ghar: Muft Bijli Yojana. Money is paid straight into your bank account by DBT after commissioning.
The slab structure for residential rooftops:
- First 1 kW → ₹30,000
- Up to 2 kW → ₹60,000
- 3 kW and above → ₹78,000 (the ceiling)
So your 3kW system qualifies for the maximum ₹78,000. There is no statewide top-up that stacks on top of this for the average household. (The only narrow exception is the HAREDA support reserved for Antyodaya / low-income families with annual income up to ₹1.80 lakh — not something a typical homeowner should bank on.)
What You Actually Pay
| | Amount | |---|---| | Gross system cost | ₹1,65,000 – 1,95,000 | | Less PM Surya Ghar subsidy | – ₹78,000 | | Net out-of-pocket | ₹87,000 – 1,17,000 |
That is the real number — a one-time spend for an asset that keeps producing electricity for the next 25 years.
Paying Over Time
Not everyone wants to clear the whole amount upfront, and you don't have to. Several banks run dedicated rooftop-solar loans:
- Principal: ₹1.5 – 2 lakh (financed on the pre-subsidy price; subsidy later reduces what you owe)
- Rate: around 7 – 9% p.a.
- Tenure: 3 – 5 years
- Indicative EMI: ₹3,500 – 4,500/month on a 5-year term
For most households the monthly EMI sits below the electricity bill it replaces — so the system effectively pays for itself while you hold the loan.
How Quickly It Pays Back
A 3kW array in Faridabad's climate produces roughly 360 units a month. Against the DHBVN domestic tariff, which averages about ₹7 per unit:
- Monthly bill saved: 360 × ₹7 ≈ ₹2,520
- Annual saving: ≈ ₹30,000
On a net cost of ₹87,000 – ₹1,17,000, that works out to a payback of roughly 3 to 4 years. Everything generated after that is essentially free power for the remaining two decades of the panels' life — and since grid tariffs tend to creep up 3-5% a year, your real saving grows over time.
What a Fair Quote Should Cover
When you install through a DHBVN-registered company like us, the price should be genuinely turnkey — no surprise add-ons later:
- Site survey, shadow analysis and system design
- Solar modules with a 25-year performance warranty
- Inverter with 5-10 year warranty
- Hot-dip galvanised mounting structure
- DC and AC surge protection
- Lightning arrestor and proper earthing
- Bidirectional net meter installation
- Full DHBVN registration and paperwork
- End-to-end PM Surya Ghar subsidy filing
- 5 years of free maintenance (3 visits a year)
If a quote is suspiciously cheap, check what has been quietly left out — usually the structure quality, surge protection, or post-install service.
