Your electricity bill is climbing every month. Your neighbour just installed solar. And you're wondering what will a solar panel for your home actually cost in 2026?
You're not alone. Over 1 crore Indian homeowners have already registered under the PM Surya Ghar Muft Bijli Yojana and thousands more are making the switch every week. Solar has never been more accessible, more affordable, or more rewarding for Indian households.
This guide answers every question you have about the cost of solar panel for home in India from system prices and government subsidies to the technology choice that determines how much electricity your panels generate over the next 25 years.
The price of solar panel for home in India depends on three things: the size of your system, the technology of the panels, and whether you claim the PM Surya Ghar government subsidy.
Here is the current price range for complete rooftop solar systems in 2026:
| System Size | Ideal For | Price Before Subsidy | Subsidy | Price After Subsidy |
|---|---|---|---|---|
| 1 kW | 1BHK, low consumption | ₹50,000-75,000 | ₹30,000 | ₹20,000-45,000 |
| 2 kW | 2BHK, moderate use | ₹1,00,000-1,40,000 | ₹60,000 | ₹40,000-80,000 |
| 3 kW | 2-3BHK, 1-2 ACs | ₹1,50,000-2,00,000 | ₹78,000 | ₹72,000-1,22,000 |
| 5 kW | Large home, high use | ₹2,50,000-3,50,000 | ₹78,000 | ₹1,72,000-2,72,000 |
These prices include solar panels, inverter, mounting structure, wiring, and installation. They are indicative ranges; actual pricing varies by brand, panel technology, inverter type, and your location.
What affects the price most? Panel technology.
A Mono PERC panel and an N-Type TOPCon panel of similar wattage differ by approximately ₹4-6 per watt, a gap of ₹12,000-18,000 on a 3kW system. But that upfront difference is recovered within the first 2-3 years through higher electricity generation. After that recovery, your TOPCon system continues outperforming PERC for the remaining 22+ years of its life.

Most buyers focus only on the panel price. But the total cost of a solar panel for home includes several components and understanding each one helps you evaluate quotes more accurately.
| Component | Share of Total Cost |
|---|---|
| Solar panels | 50-60% |
| Inverter | 15-20% |
| Mounting structure | 10-15% |
| Wiring & safety equipment | 5-8% |
| Installation charges | 5-10% |
The solar panel is the most important cost decision you make because it determines your system's output for the next 25-30 years. Every other component is largely fixed in cost regardless of panel technology.
Return on investment. For a standard 3kW rooftop system in Gujarat, the monthly electricity savings range from ₹2,000-4,000 depending on your consumption and local tariff. At that savings rate, most systems recover their post-subsidy cost within 4-5 years leaving 20+ years of near-free electricity generation.
The solar panel for home cost in India has fallen significantly over the past five years and is expected to remain stable through 2026–2027 as domestic manufacturing scales under the PLI scheme.
The PM Surya Ghar Muft Bijli Yojana is the most significant government solar scheme ever launched in India. It provides direct central subsidy for residential rooftop solar installations reducing the upfront cost of solar panel for home substantially.
| System Size | Subsidy Amount |
|---|---|
| 1 kW | ₹30,000 |
| 2 kW | ₹60,000 |
| 3 kW or above | ₹78,000 |
The subsidy is calculated on system capacity not on panel technology. This means a TOPCon buyer receives exactly the same subsidy as a PERC buyer but generates more electricity over the life of the system. Same government support. Better long-term outcome.
Who is eligible? Any residential electricity consumer with a valid connection from their DISCOM is eligible. The property must be owned (not rented), and the system must be installed by a registered vendor.
How to apply: Visit pmsuryaghar.gov.in, register with your electricity consumer number, select a registered vendor, and apply online. The subsidy is credited directly to your bank account after inspection and grid connection.
Critical requirement: Only panels listed on the MNRE ALMM portal qualify for the subsidy. Always verify the exact module model number on the ALMM portal before finalising your purchase, not just the brand name.
Atal Solar's G12R and M10R series are BIS certified and ALMM listed fully eligible for PM Surya Ghar subsidy.
The 3kW system is the most popular choice for Indian households in 2026 and the most common PM Surya Ghar application size. Here is everything you need to know about it.
A 3kW rooftop solar system can comfortably run lights, ceiling fans, television, refrigerator, washing machine, and one air conditioner simultaneously during peak sunlight hours. It generates approximately 12-15 units of electricity per day enough to significantly reduce or eliminate the electricity bill of a typical 2-3BHK Indian home.
How many panels do you need?
| Panel Technology | Wattage per Panel | Panels Needed for 3kW | Roof Space Required |
|---|---|---|---|
| Mono PERC | 440W | 7–8 panels | ~210 sq ft |
| N-Type TOPCon | 620W | 5 panels | ~150 sq ft |
This is where high-efficiency TOPCon panels deliver a direct, visible advantage for small and medium rooftops. Five panels instead of seven or eight saving approximately 60 sq ft of roof space while delivering the same or higher system capacity.
3kW solar panel price in India 2026:
After the payback period, you generate electricity at virtually zero cost for the remaining 20+ years of the system's life.
When evaluating solar panels for your home, five factors determine long-term value: efficiency, degradation, temperature performance, roof space, and warranty. N-Type TOPCon leads on all five.
| Factor | Mono PERC | N-Type TOPCon |
|---|---|---|
| Efficiency | 19-21% | 22-24% |
| Panels needed for 3kW | 7-8 panels | 5 panels |
| Roof space for 3kW | ~210 sq ft | ~150 sq ft |
| LID (Day 1 loss) | 1-3% permanent | Zero LID |
| Temperature coefficient | −0.35%/°C | −0.29%/°C |
| Performance warranty | 25-year stepped | 30-year linear |
For homeowners claiming PM Surya Ghar subsidy, the case is clear: the subsidy amount is identical for PERC and TOPCon. Choosing TOPCon means getting more electricity from the same government support for the next 30 years.

A complete rooftop solar system for home costs ₹50,000–75,000 for 1kW, ₹1,00,000–1,40,000 for 2kW, and ₹1,50,000-2,00,000 for 3kW before subsidy. After the PM Surya Ghar subsidy of up to ₹78,000, a 3kW system costs ₹72,000-1,22,000 depending on panel technology and brand.
The total cost includes solar panels (50-60%), inverter (15-20%), mounting structure (10-15%), wiring (5-8%), and installation (5-10%). For a 3kW system, the all-inclusive cost before subsidy ranges from ₹1,50,000-2,00,000.
The PM Surya Ghar Muft Bijli Yojana offers ₹30,000 for 1kW, ₹60,000 for 2kW, and ₹78,000 for 3kW systems. Apply at pmsuryaghar.gov.in with your electricity consumer number. Only ALMM-listed panels qualify.
With N-Type TOPCon panels at 620W, you need only 5 panels for a 3kW system requiring approximately 150 sq ft of roof space. With Mono PERC at 440W, you need 7-8 panels and approximately 210 sq ft. TOPCon delivers the same system capacity with fewer panels and less roof space.
N-Type TOPCon is the best solar panel for homes with limited roof space. At 22-24% efficiency and up to 650Wp per panel, TOPCon generates significantly more electricity per square foot than Mono PERC. For Indian homes with compact rooftops, fewer panels means the same or higher output with Zero LID and a 30-year linear warranty.
2026 is the best time in India's history to install solar panels for your home. The PM Surya Ghar subsidy reduces upfront costs by up to ₹78,000. Panel prices have stabilised. And N-Type TOPCon technology now delivers 23.5%+ efficiency at a price premium that is recovered within 2-3 years.
For most Indian homeowners whether you have a compact 2BHK rooftop or a larger terrace the combination of government subsidy and TOPCon technology makes rooftop solar the clearest long-term investment available today.
