Solar Panel Price in India 2026: Per Watt, By Wattage & System Size

If you have been searching for the solar panel price in India, you have probably noticed a frustrating pattern. Every website gives you a different number, most pages want you to buy before they tell you anything, and almost nobody explains what actually decides the price.

This guide fixes that. We break down solar panel rates in India the way a buyer actually needs them: price per watt, price by panel wattage, price by system size from 1kW to 10kW, and what changes once the government subsidy is applied. Whether you typed 3kW, 3 KV, or even "3 kg" solar panel price into Google, this is the complete answer.

One note before we begin. Solar module prices change with technology, demand, and policy, so treat every figure here as an indicative market range, not a fixed quote. For an exact price for your home or business, talk to our solar experts or WhatsApp us at +91 90990 88489.

What decides solar panel price in India?

Four factors control nearly the entire price of a solar panel:

1. Technology

N-Type TOPCon, Mono PERC, and polycrystalline panels sit at different price points because they deliver very different efficiency and lifetime output. If these terms are new to you, start with our guide to the types of solar panels.

2. Wattage

A 550 Wp panel costs more than a 100 Wp panel, but usually less per watt. Higher wattage means fewer panels, less mounting structure, and less labour for the same system size.

3. Certifications

BIS certified panels from ALMM listed manufacturers cost slightly more than uncertified imports, but only ALMM listed modules qualify for the government subsidy. You can verify any manufacturer on the official ALMM list published by MNRE.

4. Scale

Per-watt pricing falls as system size grows, which is why a 10kW commercial system has a much lower rate per watt than a 1kW home system.

Solar panel price per watt in India (by technology)

Per-watt pricing is the cleanest way to compare solar module prices across brands and technologies. Here is where the Indian market stands in 2026 for the panel alone, excluding inverter, structure, and installation:

Technology	Indicative price/watt	Efficiency range	Best for
Polycrystalline	₹20 to ₹26	16 to 17%	Budget, low-priority loads
Mono PERC	₹24 to ₹30	19 to 21%	General rooftop use
N-Type TOPCon	₹27 to ₹34	22 to 24%	Max output, limited roof, long-term value
HJT	₹30 to ₹38	22 to 24%	Premium niche, limited India availability

Two things stand out. First, the gap between Mono PERC and N-Type TOPCon pricing has narrowed sharply as Indian TOPCon manufacturing capacity has scaled. Second, the per-watt sticker price does not tell you the full story, because a TOPCon panel generates more electricity from the same roof for 25 to 30 years. We cover that in the value section below, and our detailed TOPCon solar panel price guide goes deeper on this specific technology.

Solar panel price by wattage

Buying individual panels rather than a full system? Here is the indicative price band by panel wattage. Remember the rule: the higher the wattage, the lower the effective cost per watt.

Panel wattage	Indicative price range	Typical use
100 watt	₹2,800 to ₹4,000	Small DC loads, street lighting
200 watt	₹5,000 to ₹7,000	Small off-grid setups
250 watt	₹6,000 to ₹8,000	Off-grid and hybrid kits
300 watt	₹7,000 to ₹9,500	Small rooftop systems
500 watt	₹11,000 to ₹14,500	Modern rooftop systems
550 watt	₹12,000 to ₹16,000	Rooftop and commercial
600 to 650 watt	₹15,000 to ₹20,000	High-density rooftop, C&I projects

The 500 Wp and above segment is where the Indian market is moving fastest. Modern half-cut cell modules in the 600 to 650 Wp class, like Atal Solar's M10R 156 Series up to 650Wp, pack more power into every square metre of roof, which cuts structure and installation cost per kW. Our G12R vs M10R comparison guide explains which format suits which project.

Solar panel price by system size (1kW to 10kW)

For homes and businesses, the more useful number is the complete system price: panels, inverter, mounting structure, cabling, and installation together. Here is the 2026 market picture before subsidy:

System size	Indicative system price (before subsidy)	Roof space needed	Best for
1 kW	₹60,000 to ₹70,000	~100 sq ft	1 BHK, basic loads
2 kW	₹1,20,000 to ₹1,40,000	~200 sq ft	Small family home
3 kW	₹1,80,000 to ₹2,00,000	~300 sq ft	2 to 3 BHK, one AC
4 kW	₹2,40,000 to ₹2,70,000	~400 sq ft	Larger home
5 kW	₹3,00,000 to ₹3,40,000	~500 sq ft	Big home, multiple ACs
10 kW	₹5,50,000 to ₹6,50,000	~1,000 sq ft	Shops, offices, small factories

A quick note on that 3kW row, since 3 kilowatt solar panel price is the single most searched system size in India. The 3kW system is the sweet spot for most Indian households because it covers typical daily consumption and attracts the maximum government subsidy, which brings us to the next section.

Solar panel price with subsidy (PM Surya Ghar Yojana)

The PM Surya Ghar Muft Bijli Yojana changes the arithmetic completely for residential buyers. The central government pays a direct subsidy into your bank account after installation, and applications run entirely through the official portal at pmsuryaghar.gov.in

System size	Subsidy	Indicative net cost after subsidy
1 kW	₹30,000	₹30,000 to ₹40,000
2 kW	₹60,000	₹60,000 to ₹80,000
3 kW and above	₹78,000 (capped)	₹1,00,000 to ₹1,20,000 for 3 kW

Two conditions matter here. The subsidy applies only to residential installations, and only when the system uses ALMM listed panels installed by a portal-registered vendor. For the complete eligibility rules, documents, and step-by-step application process, read our full PM Surya Ghar Yojana subsidy guide.

Solar panel installation cost: the part most price lists hide

When websites quote a panel-only rate, they quietly leave out 30 to 40 percent of your real project cost: the inverter, mounting structure, DC and AC cabling, earthing, net metering, and labour. That is why a "cheap" panel quote can end up as an expensive system.

As a rule of thumb in 2026, installation and balance-of-system components add roughly ₹20,000 to ₹35,000 per kW on top of the module cost, depending on roof type and location.

Why the cheapest panel is rarely the cheapest electricity

Here is the trap most first-time buyers fall into: comparing panels only on upfront price.

A solar panel is not a one-time purchase. It is a 25 to 30 year electricity generator, so the number that actually matters is the cost of every unit of electricity it will produce over its lifetime, a metric the industry calls LCOE, or levelised cost of energy. On that measure, a higher-efficiency panel usually wins even at a higher sticker price, because it produces more units from the same roof for decades.

This is exactly why N-Type TOPCon technology is taking over the Indian market. Compared to standard panels, TOPCon modules offer:

• Higher efficiency, up to 23.51% in Atal Solar's G12R 132 Series. so fewer panels and less roof space per kW
• Better weak-illumination response, which means stronger generation during monsoon months and winter mornings
• Zero light-induced degradation in the first year, unlike P-Type panels
• Stronger long-term performance warranties, explained in our solar panel warranty guide

If you want the full technical comparison, our N-Type vs P-Type guide. covers it in depth. The short version: paying a few rupees more per watt for a BIS certified, Made in India TOPCon module from a fully automated manufacturing line typically buys you the lowest electricity cost over the life of the system.

How to get an accurate solar price for your home or business

Online price ranges get you oriented. An accurate quote needs three inputs: your average monthly electricity bill, your usable shadow-free roof area, and your location. With those, a manufacturer can size the system correctly and give you a real number instead of a guess.

Here is the fastest way to do it:

• Check your last three electricity bills for average monthly units.
• Estimate your shadow-free roof area between 9 AM and 4 PM.
• Run the numbers on our Solar Calculator.
• WhatsApp us at +91 90990 88489 for an exact quote on high-efficiency N-Type TOPCon modules manufactured in Rajkot, Gujarat.
