Solar Panel Price in India (2026 Updated): Cost, Subsidy and Monthly Savings
Last updated at : Aug 13, 2026
Solar panel prices in India have settled into a comfortable range in 2026, making rooftop solar a genuinely smart financial decision for most households. Whether you want to trim a small bill or eliminate a large one, there is a system size to match. Here is an updated look at what solar costs, what the subsidy saves you and how quickly it pays back.
Solar Panel Price by System Size
| System Size | Approx. Cost (Before Subsidy) | Best For |
|---|---|---|
| 1kW | ₹80,000 – 1.2 lakh | Small homes, basic loads |
| 3kW | ₹1.8 – 2.5 lakh | Average families |
| 5kW | ₹2.5 – 3.5 lakh | Homes with AC, many appliances |
| 10kW | ₹5 – 7 lakh | Large homes, small offices |
These are complete installed prices that include panels, inverter, mounting, wiring and commissioning. Premium panels, branded inverters or battery backup move you toward the higher end of each band.
What Determines the Price
- Panel type — TOPCon and mono PERC cost more but generate more power per square foot.
- System type — on-grid is the cheapest; hybrid and off-grid add battery cost.
- Inverter quality — a key factor in both price and long-term reliability.
- Roof and location — structure type, accessibility and local rates all matter.
Subsidy: How Much You Save
The PM Surya Ghar scheme offers a residential rooftop subsidy of up to ₹78,000, reached at a 3kW system. Here is a simple example of how it changes the maths:
A 5kW system costing about ₹3 lakh before subsidy drops to roughly ₹2.2 lakh after the ₹78,000 subsidy is applied.
Some states layer their own incentive on top, so your real net cost can be even lower.
Generation, Savings and Payback
A properly sized system can cut your bill by 70–90%. Typical numbers:
- Payback period: 3–5 years
- System lifespan: 20+ years
- After payback, electricity is effectively free for the rest of the system's life
This combination of a short payback followed by decades of savings is what makes solar one of the safest investments a homeowner can make today.
Which Size Should You Buy?
The easiest way to choose is to look at your monthly bill:
- Bill under ₹2,000 — a 1kW system may be enough
- Bill ₹2,000–4,000 — consider 3kW for the full subsidy
- Bill ₹5,000–8,000 — a 5kW system is ideal
- Bill ₹15,000+ — look at 10kW or larger
Most homes land on a 3kW or 5kW residential solar system. If the upfront cost is a concern, solar loans let you pay in EMIs while your savings help cover the instalment.
Are Solar Panels Worth It in 2026?
Yes, for most homes. Prices are stable, the subsidy is substantial, and electricity tariffs keep climbing. A system that pays for itself in a few years and then generates near-free power for two more decades is hard to beat. The earlier you install, the more you save over the system's life.
