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, or searched for the solar plate rate, solar panels price, or solar panel price list, 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.

The three solar panel prices you should not mix up

Most of the confusion around solar panel price in India, and the solar plate rate people often ask about, comes from comparing three different numbers without realising it:

• Panel-only price. What the module itself costs per watt, excluding inverter, structure, cabling, and labour. This is usually the number behind a bare "solar plate rate" or "solar panels price" search.
• Installed system price (before subsidy). Panel plus everything needed to get it generating electricity on your roof. This is the number on an actual installer quote.
• Your net cost (after subsidy). What you actually pay once the PM Surya Ghar subsidy, or any state top-up, is applied.

Keep these three apart and every price list on the internet, including this one, becomes much easier to read.

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.

For how this per-watt figure is actually built, cell cost, materials, automation and the DCR premium, see our solar panel price per watt guide.

Solar panel price by brand in India (2026)

Searches for "Adani vs Waaree vs Tata vs Vikram solar panel price" are common, and the honest answer is that brand price sits inside the same technology bands covered above, not in its own separate scale:

Brand	Primary technology focus	Typical price band
Adani Solar	Mono PERC, TOPCon	Mono PERC to TOPCon range
Waaree Energies	Mono PERC, TOPCon	Mono PERC to TOPCon range
Vikram Solar	Mono PERC, TOPCon	Mono PERC to TOPCon range
Tata Power Solar	Mono PERC, TOPCon	Mono PERC to TOPCon range
Atal Solar	N-Type TOPCon only	TOPCon range, 1.44 GW ALMM listed, BIS approved

Treat any brand-specific rupee figure you see online with caution, exact pricing moves with order volume, region, and the month's input costs, so it varies within the technology band rather than sitting at one fixed number. What is more reliable to compare is which technology a brand is actually shipping for your order, since that is what the price band in the table above actually tracks. Our N-Type vs P-Type guide explains why that technology choice matters more than the brand name on the box.

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 watt (TOPCon)	₹8,400 to ₹10,800 non-DCR; ₹13,200 to ₹16,800 DCR	High-density rooftop, C&I projects
650 watt (TOPCon)	₹9,100 to ₹11,700 non-DCR; ₹14,300 to ₹18,200 DCR	C&I and ground-mount 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.

600 watt and 650 watt solar panel price

Searches for a "600 kW" or "650 kW" solar panel price almost always mean a single 600 W or 650 W panel; a 600 kW system would be an industrial plant of about 1,000 such panels. At October 2026 prices, before 5% GST, a 600 W N-Type TOPCon panel costs about ₹8,400 to ₹10,800 non-DCR and ₹13,200 to ₹16,800 DCR. A 650 W panel costs about ₹9,100 to ₹11,700 non-DCR and ₹14,300 to ₹18,200 DCR.

Atal Solar makes both sizes: the M10R 144 Series up to 600 W and the M10R 156 Series up to 650 Wp. For current prices by brand, see our TOPCon solar panel price guide.

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.

Full system cost, worked example (3kW and 5kW)

Price tables are easier to use with real numbers run through them once. Here is the complete math for the two most searched system sizes:

Step	3 kW system	5 kW system
Installed price before subsidy	₹1,80,000 to ₹2,00,000	₹3,00,000 to ₹3,40,000
PM Surya Ghar subsidy	− ₹78,000	− ₹78,000
Net cost after subsidy	₹1,02,000 to ₹1,22,000	₹2,22,000 to ₹2,62,000
Typical daily generation	12 to 15 units	20 to 25 units
Approx. monthly saving at ₹8/unit	₹2,900 to ₹3,600	₹4,800 to ₹6,000

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
• Optional dual-glass bifacial construction, adding rear-side generation for ground-mount or elevated installations

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.

Solar quote checklist: 7 things to ask before you pay

A low price per watt means little if these seven items are not confirmed in writing:

1. Is the exact module model, not just the brand, on the current ALMM List?
2. Is the price quoted panel-only, or the complete installed system?
3. What is the degradation warranty figure at year one, not just the headline warranty length? See our degradation guide for what good looks like.
4. Does the quote include net metering application and liaison with the DISCOM?
5. What inverter brand and warranty is included, and is it sized correctly for the panel array?
6. Is the installer registered on the PM Surya Ghar portal, a requirement for subsidy disbursal?
7. What does the full product and performance warranty actually cover, and for how long?

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. If you would rather shortlist suppliers first, our guide compares the top solar panel manufacturers in Gujarat.

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 Morbi district, Gujarat.

3. What is the price of a 3kW solar system with subsidy?

A 3kW residential system indicatively costs ₹1,80,000 to ₹2,00,000 before subsidy. After the ₹78,000 PM Surya Ghar subsidy, the net cost typically falls to ₹1,00,000 to ₹1,20,000. Figures as of July 2026; confirm current amounts at pmsuryaghar.gov.in.

4. Does the government subsidy apply to every solar panel?

No. Only ALMM listed modules installed through registered vendors qualify. Always verify the specific module model, not just the brand, before purchase.

5. Why do TOPCon panels cost more than normal panels?

TOPCon panels use an advanced N-Type cell architecture that delivers higher efficiency, zero first-year light-induced degradation, and better low-light output. They cost more per watt upfront but usually produce cheaper electricity over 25 to 30 years.

6. How can I calculate the solar panel price for my home?

Use a solar panel price calculator that factors in your monthly units and roof size. Atal Solar's free Solar Calculator gives you an instant estimate, and our team can convert it into an exact quote on WhatsApp.

7. What is "solar plate rate"?

Solar plate rate is the common colloquial term for solar panel price per watt, the cost of the module itself, before inverter, structure, cabling, and installation are added. In 2026, this ranges from roughly ₹20 to ₹38 per watt depending on technology.

8. What is the solar panels price list for 2026?

By wattage, individual panels range from about ₹2,800 for a 100 watt panel to ₹20,000 for a 650 watt module. By complete system, installed cost runs from about ₹60,000 for 1 kW to ₹6,50,000 for 10 kW, before subsidy. Both tables are above on this page.

9. Is a cheaper solar panel price always a better deal?

No. A lower price per watt often means an older, lower-efficiency technology or a non-DCR module that cannot claim subsidy. Compare lifetime electricity cost (LCOE) and the degradation warranty, not just the sticker price per watt.

10. What is the commercial solar panel price per watt in India?

Commercial and industrial buyers generally see the same per-watt technology bands as residential buyers, but a lower overall system price per watt because balance-of-system costs spread across a larger array. Our commercial solar panels buyer's guide covers what C&I buyers should compare beyond price.
