1kW Solar Panel Price in India (2026): Cost, Subsidy and Savings Guide
Last updated at : Aug 13, 2026
A 1kW solar panel system is the smallest practical setup for an Indian home, and it is often where first-time buyers start. It suits small households, single-floor homes or anyone who wants to test solar before scaling up. Here is a plain-English look at what a 1kW system costs in 2026 and what it can do for your electricity bill.
1kW Solar System Price in 2026
A 1kW system in India usually costs between ₹25,000 and ₹60,000, depending on the type of system and component quality. The wide range comes down to a few choices:
| Factor | Lower Cost | Higher Cost |
|---|---|---|
| System type | Off-grid / basic on-grid | Hybrid with battery |
| Panel technology | Polycrystalline | Mono PERC / TOPCon |
| Inverter and structure | Standard | Premium, branded |
On-grid systems sit at the affordable end because they have no batteries. Adding battery backup for power cuts pushes the price toward the upper end.
How Much Power a 1kW System Generates
A 1kW system in India typically produces:
- About 4 units (kWh) per day
- Around 120 units per month
- Roughly 1,440 units per year
That covers basic loads like lights, fans, a TV, a fridge and phone charging for a small home. Actual output depends on your location, roof orientation and how clean the panels are kept.
Subsidy on a 1kW System
Under the PM Surya Ghar: Muft Bijli Yojana, residential rooftop systems qualify for a central subsidy. For a 1kW system the central subsidy is around ₹30,000, which significantly lowers your net cost. Some states add their own top-up, so it is worth checking the combined benefit in your state.
Savings and Payback
A 1kW system trims a meaningful slice off a small home's bill. With the subsidy applied, the net investment is modest, and most owners recover it within a few years through monthly savings. After that, the system keeps generating for the rest of its life.
- System lifespan: up to 25 years
- Panels carry long performance warranties
- Maintenance is minimal, mostly periodic cleaning
Is 1kW Enough for Your Home?
A 1kW system is ideal if:
- Your monthly bill is small
- You live in a compact home with limited roof space
- You want a low-cost entry into solar
If your bill is higher or you run an AC, a residential solar system of 3kW or 5kW will give you better returns. The good news is you can start with 1kW and expand later. If the upfront amount is a hurdle, solar loans let you pay in easy instalments.
