1kW Solar Panel Price in India 2026 (Full Breakdown)
I get asked the same question every week by first-time buyers: "what will a 1kW solar panel actually cost me?" The honest answer is that the sticker price and the price you pay are two different numbers, and most dealer quotes only show you one of them.
A 1kW rooftop solar system in India costs roughly ₹65,000 before subsidy, working out to ₹28-₹36 per watt for TOPCon panels or ₹26-₹30 per watt for polycrystalline. After the PM Surya Ghar central subsidy of ₹30,000 for a 1kW system, your out-of-pocket cost drops to around ₹35,000. That's the number I want you to remember, not the inflated "market rate" figures floating around online.

1kW Solar Panel Price in India: What You're Actually Paying For
When I break a 1kW quote down for a client, four line items make up the total: the panel itself, the inverter, the mounting structure and wiring, and installation labour. Panels alone (roughly 2-3 units of 330-450W, or a single high-wattage module) account for 55-60% of the cost. The inverter is usually 15-20%. Everything else, structure, cabling, earthing, and labour, fills the rest.
Where I see buyers get overcharged is in that "everything else" bucket. A fair 1kW on-grid installation shouldn't run past ₹70,000 before subsidy in most Indian cities. If a quote comes in meaningfully higher, ask what's driving it: premium panel brand, extended warranty, or genuinely inflated margins.
1kw Solar Panel Price in India: On-Grid vs Off-Grid vs Hybrid
This is where the "1kw solar panel price in india" search gets murky, because the number changes hugely by system type.
System Type | Approx. Price (1kW) | Battery Included | Works During Power Cut |
|---|---|---|---|
On-grid | ₹60,000-₹70,000 | No | No |
Hybrid | ₹95,000-₹1,20,000 | Small battery, optional | Yes, limited |
Off-grid | ₹1,10,000-₹1,50,000 | Yes, mandatory | Yes, full |
If someone quotes you ₹35,000 for a "complete 1kW solar system" without specifying on-grid, that's usually the pre-subsidy on-grid price being marketed as the final price. I'd ask them to write down the subsidy separately before signing anything.
The Subsidy Math Nobody Shows You
The PM Surya Ghar scheme gives you ₹30,000 for a 1kW system, but the subsidy structure isn't linear. It's ₹60,000 for 2kW and caps at ₹78,000 for 3kW and above. In other words, the government front-loads the incentive on the first 2kW and then tapers it off. If your rooftop can technically support 2kW, stopping at 1kW leaves subsidy money on the table.
A few states add their own top-up. Delhi offers a generation-based incentive of ₹3 per unit for systems up to 3kW, which can add another ₹20,000-₹30,000 over five years. Uttar Pradesh adds up to ₹30,000 in state subsidy. Haryana currently offers no additional state-level bonus on top of the central scheme (verify at publish, state schemes are revised often).
1 Kilowatt Solar Panel Price: Is It Actually Worth It at This Size?
I'll be honest about the trade-off here, because most commercial pages won't tell you this part. A 1kW system generates roughly 4-5 units a day, which covers a small household running a fridge, a few fans, lights, and a TV. It will not run an AC or a geyser for any meaningful stretch. If your monthly bill is already above ₹1,500-2,000 (check your actual per-unit rate before assuming), a 1kW system will barely dent it, and you'd be better off sizing to 2kW or 3kW from the start using the full solar panels for home cost breakdown, since the per-watt cost drops and the subsidy is more generous up to 2kW anyway.
Pros and Cons of a 1kW Solar Panel System
Pros:
- Lowest entry cost for rooftop solar, good for testing the technology before scaling up
- Subsidy-to-cost ratio is strong (nearly 46% of the pre-subsidy price is covered)
- Minimal roof space needed (80-100 sq. ft.), works for small terraces
- Simple, quick installation, typically 1-2 days
Cons:
- Won't run high-load appliances like ACs or geysers meaningfully
- Per-watt cost is higher than 2kW or 3kW systems, since fixed costs (labour, wiring, net metering paperwork) don't scale down
- You leave subsidy value on the table since the 2kW slab is proportionally more subsidised
- Payback period is often longer in absolute years for very small systems if your usage doesn't match generation closely
Who a 1kW System Suits (and Who It Doesn't)
Strong fit: small households with 1-2 people, low monthly consumption (under 150 units), limited rooftop space, or anyone wanting to test rooftop solar before a larger investment.
Marginal fit: households with 3-4 people and moderate consumption (150-250 units) where a 2kW system would serve better economics without much extra cost.
Not a fit: homes running an AC, electric geyser, or heavy motor loads regularly. A 1kW system won't meaningfully offset that consumption, and you'll likely feel like the investment "didn't work" even though it performed exactly as sized.
Step-by-Step: Getting Your 1kW System Priced and Installed
- Get your last 3 electricity bills to confirm your actual monthly consumption in units.
- Confirm rooftop shadow-free area (minimum 80-100 sq. ft. for 1kW).
- Register on the PM Surya Ghar national portal before you finalise a vendor, since only empanelled installers qualify you for the subsidy.
- Collect at least 2-3 vendor quotes and insist the pre-subsidy and post-subsidy prices are shown separately.
- Confirm the panel brand meets Domestic Content Requirement (DCR) if you want state-level top-ups.
- Install, get net metering approved by your DISCOM, and the subsidy is credited to your bank account, not deducted upfront by most vendors (verify this with your specific installer).
FAQs
What is the price of a 1kW solar panel in India?
A 1kW solar panel system costs approximately ₹65,000 before subsidy in 2026, or around ₹35,000 after the PM Surya Ghar central subsidy of ₹30,000. Prices vary by city and panel brand, so always get a written quote.
What is the 1kw solar panel price in India after subsidy?
After the ₹30,000 central subsidy, expect to pay approximately ₹35,000 for a 1kW on-grid system. Add state-level incentives where available (Delhi, Uttar Pradesh) to reduce this further.
How much does a 1 kilowatt solar panel price change between on-grid and off-grid?
On-grid systems cost ₹60,000-₹70,000, while off-grid systems with battery backup cost ₹1,10,000-₹1,50,000 for the same 1kW capacity, since batteries add significant cost.
How many units does a 1kW solar panel generate per day?
A 1kW system typically generates 4-5 units per day in most Indian cities with average sunlight, though this varies with roof orientation, shading, and seasonal irradiance.
Is a 1kW solar system enough for a home?
It's enough for very small households with low consumption (fridge, fans, lights, TV). It is not sufficient for homes running an AC or geyser regularly.
How much roof space does a 1kW solar system need?
Approximately 80-100 square feet of shadow-free rooftop area.
Does the 1kW solar panel price include installation?
Most vendor quotes for ₹60,000-₹70,000 include panels, inverter, mounting structure, wiring, and installation labour. Always confirm this is inclusive before comparing quotes.
How do I apply for the PM Surya Ghar subsidy on a 1kW system?
Register on the PM Surya Ghar national portal, select an empanelled vendor, complete installation, and apply for net metering through your DISCOM. The subsidy is typically credited to your bank account after commissioning, not deducted upfront (confirm with your installer).
