Solar Panel Price in India (2026): Complete Guide to Costs, Subsidies & Savings

Are you planning to install solar but confused about how much it will actually cost? 

When you search for solar panel prices in India, the prices you see online can be confusing because some refer only to the solar panels, while others cover the complete rooftop solar system. A complete system includes much more than the panels themselves. 

The final cost depends on factors such as the system capacity, panel technology, inverter, mounting structure, installation requirements, location, and applicable government subsidy. 

For example, two 3kW solar systems can have different prices depending on the panels and inverter used, the quality of the mounting structure, your roof conditions, and what installation and after-sales services are included in the quotation. 

That's why comparing only the headline price can give you an incomplete picture.

Let’s break down the complete solar system price in India in 2026, including costs for different system sizes, price per watt, government subsidy, electricity generation, savings, payback period, and the factors you should compare before choosing a rooftop solar system.

The final quotation can still vary depending on panel and inverter specifications, mounting structure, roof conditions, location, electrical work, and other installation requirements. 

What Does a Complete Rooftop Solar System Include?

A complete rooftop solar system includes much more than solar panels. The panels generate electricity, but the inverter, mounting structure, cables, safety equipment, installation and grid connection are all needed to make the system work safely and efficiently. 

Solar Panels​

Solar panels convert sunlight into DC electricity. Their technology, wattage and efficiency affect how much electricity can be generated from the available roof space. 

Solar Inverter​

The inverter converts the DC electricity produced by the panels into AC electricity that can be used by your household appliances or supplied to the grid. Inverter efficiency, warranty and quality can therefore affect both system performance and price. 

Mounting Structure

The mounting structure securely holds the panels and positions them to receive sufficient sunlight. Its design depends on factors such as the roof type, system layout and installation requirements. Freyr notes that aluminium and galvanised steel are commonly used for solar mounting structures. 

DC & AC Cables

Solar cables carry electricity between the panels, inverter and electrical system. Correct cable selection and sizing are important because unsuitable cables can increase electrical losses and affect system performance. 

Protection & Electrical Components

A complete system also requires safety components such as ACDB, DCDB, earthing, isolators, fuses, and surge protection devices. Lightning protection may also be required depending on the installation.  

These components protect both the solar equipment and the property from electrical faults and voltage surges. 

Installation & Commissioning

Installation includes mounting the panels and inverter, completing the electrical connections, testing the system and commissioning it for operation. Before commissioning, the electrical components and safety measures should be checked to identify any faults. 

Net Metering & DISCOM-Related Services

For an on-grid system, a bidirectional meter records electricity imported from and exported to the grid. Freyr states that its project management includes support for solar subsidy and net-metering processes. 

The key point: a ₹/W figure for solar modules alone cannot be directly compared with the quotation for a complete installed rooftop system. When comparing solar system prices, check exactly which equipment, installation work, safety components, warranties and services are included in the final quotation. 

Solar System Price by Capacity

The cost of a rooftop solar system increases with its capacity, but a larger system also generates more electricity and can deliver higher savings.  

The right capacity should therefore be based primarily on your electricity consumption and available roof space, rather than the size of your house alone. 

As a general benchmark, a 1kW rooftop system can generate around 4 units of electricity per day, although actual generation varies with location, sunlight, shading, weather and system design. 

1kW Solar System Price

A 1kW solar system costs around ₹1.20–₹1.30 lakh based on the pricing used in this guide. Eligible residential consumers can receive a central subsidy of ₹30,000, bringing the approximate cost down to ₹90,000–₹1 lakh.


It can generate roughly 120 units per month and generally requires around 80–100 sq. ft. of shadow-free roof space. It is suitable for small households with relatively low electricity consumption.

2kW Solar System Price

Visit a A 2kW solar system costs approximately ₹1.80–₹1.90 lakh. With a ₹60,000 central subsidy for eligible residential installations, the effective investment can fall to around ₹1.20–₹1.30 lakh.


A system of this size can generate roughly 240 units per month, depending on local conditions. It is suitable for small to medium-sized homes whose electricity consumption falls within this range.

3kW Solar System Price

Visit a A 3kW solar system costs approximately ₹2.30–₹2.40 lakh. Eligible residential consumers can receive up to ₹78,000 in central subsidy, reducing the approximate investment to ₹1.52–₹1.62 lakh.


A 3kW system can generate around 360 units per month and typically needs approximately 250–300 sq. ft. of roof space. This makes it a practical option for many Indian households with moderate electricity consumption.

5kW Solar System Price

Visit a A 5kW solar system costs around ₹3.50–₹3.70 lakh. For an eligible residential installation, the central subsidy is capped at ₹78,000, bringing the approximate effective cost to ₹2.72–₹2.92 lakh.


A 5kW system can generate around 600 units or more per month and typically requires approximately 400–500 sq. ft. of usable roof space. It is better suited to larger homes with higher electricity consumption, including households using multiple air conditioners or other high-load appliances.

10kW Solar System Price

Visit a A 10kW rooftop solar system costs approximately ₹6.30–₹6.40 lakh based on the pricing used in this guide. For an eligible residential consumer, the central subsidy remains capped at ₹78,000 rather than increasing proportionately beyond 3kW.


Based on the same generation benchmark, a 10kW system can produce approximately 1,200 units per month, although actual output will vary by location and site conditions. It is generally suited to large homes and properties with significantly higher electricity consumption.

Solar System Price Per Watt — How to Compare Quotes

Price per watt (₹/W) is a useful way to compare solar quotations of different sizes. However, it only works when you are comparing similar complete systems. A lower ₹/W does not automatically mean you are getting a better deal. 

How to Calculate Solar Price Per Watt

The formula

Solar price per watt = Total system price ÷ System capacity (in watts)

For example, if a complete 3kW solar system costs ₹2.40 lakh: 

  • ₹2,40,000 ÷ 3,000 W = ₹80/W 

If another 3kW system costs ₹2.10 lakh, its price works out to ₹70/W. 

At first glance, the ₹70/W system looks cheaper. But the comparison is incomplete until you check what both quotations actually include. 

Why ₹/W Alone Isn't Enough?

Two systems with the same capacity can have different prices because their specifications and service scope may be different. When comparing the ₹/W of two quotations, also check: 

The client’s final outline specifically requires ₹/W to be treated as a quote-comparison metric, rather than simply presenting the market price of individual solar modules. 

Example: Comparing Two Solar Quotes

Suppose you receive these quotations for a 3kW rooftop system: 

SpecificationQuote AQuote B
System capacity3kW3kW
Total price₹2.10 lakh₹2.40 lakh
Price per watt₹70/W₹80/W
Panel technologyMono PERCTOPCon
InverterStandardHigher-specification
Mounting structureStandardEnhanced specification
InstallationIncludedIncluded
MonitoringCheck quotationIncluded
WarrantyCheck individual componentsLonger component coverage
After-sales supportLimited / check scopeIncluded
Lower upfront price Higher included value

Quote A is ₹30,000 cheaper, but that alone doesn’t make it the better option. If Quote B includes higher-efficiency panels, better warranties, stronger components or more comprehensive service, the additional ₹10/W may offer better value over the system’s operating life. 

So, use price per watt to shortlist quotations, but make the final decision only after comparing them on a like-for-like basis. 

Next comes an important distinction that makes these comparisons much easier: solar panel price vs complete solar system price. 

Solar Panel Price vs Complete Solar System Price

A solar panel price usually refers only to the cost of the photovoltaic modules. A complete solar system price includes the equipment and services required to turn those panels into a working rooftop power system. 

Panel-only priceComplete solar system price
Solar modules onlyComplete rooftop solution
No inverterInverter included
No mounting structureStructure included
No installationInstallation included
No electrical BOSElectrical & safety components included
No service scopeInstallation/service scope included

This distinction is important when comparing prices online. A low module price may look attractive, but you will still need an inverter, structure, cables, protection equipment and installation. 

So, when searching for the solar panel price in India, first check whether the quoted amount refers to the panels alone or the complete installed system. 

Why Does Freyr Energy Offer Solar Systems at This Price?

Where Does Your Solar System Investment Go?

Your investment covers more than panels. It includes the inverter, mounting structure, electrical components, installation, monitoring, warranties and service support required to operate the system reliably. 

01

Why a Lower Solar Quote May Not Mean Better Value

A cheaper 3kW system and a higher-priced 3kW system are not necessarily identical products. Differences can include panel technology, inverter specifications, structure quality, warranties, installation scope, electrical work and after-sales service.

02

The right comparison is therefore:

Same capacity → Same technology → Same specifications → Same installation scope → Same warranties → Final price

Compare what is included in the quotation, not just the final price.

Solar System Cost Before & After Government Subsidy

The PM Surya Ghar: Muft Bijli Yojana provides Central Financial Assistance to eligible residential consumers installing rooftop solar. 

System capacityCentral subsidy
1kW₹30,000
2kW₹60,000
3kW or aboveMaximum ₹78,000

The subsidy is capped at 3kW, so installing a 5kW or 10kW residential solar system does not increase the central subsidy beyond ₹78,000.

For example, a 3kW system costing ₹2.30–₹2.40 lakh would have an approximate effective cost of ₹1.52–₹1.62 lakh after a ₹78,000 subsidy, subject to eligibility. 

Residential consumers with a grid-connected DISCOM connection can apply through the PM Surya Ghar National Portal. State-level incentives may also be available in some locations and should be checked separately. 

How Much Electricity Does a Solar System Generate?

Solar generation depends on sunlight, location and system design. Using an approximate benchmark of 4 units per kW per day, the following table provides a simple estimate: 

System sizeApprox. daily generationApprox. monthly generation
1kW4 units120 units
2kW8 units240 units
3kW12 units360 units
5kW20 units600 units
10kW40 units1,200 units

These figures are estimates rather than guaranteed output. Actual generation varies according to location, solar irradiation, roof orientation, shading, weather, panel efficiency and system losses. 

How Much Can You Save With a Solar System?

The amount you save with rooftop solar depends on your electricity consumption, solar system size, electricity tariff, solar generation, and applicable net-metering rules.

A properly sized rooftop solar system can meet a large portion of your household’s electricity needs and may help reduce your electricity bill by up to 90%, depending on your usage pattern and system performance.

Example: Saving With a 3 kW Solar System?

Suppose your home uses around 400 units of electricity per month and you install a 3 kW rooftop solar system.

ParticularsExample
Solar system cost₹2.35 lakh
Government subsidy₹78,000
Net investment after subsidyApprox. ₹1.57 lakh
Estimated solar generationApprox. 360 units/month
Electricity bill before solar*Approx. ₹3,200/month
Electricity bill after solar*Approx. ₹320/month
Monthly savingsApprox. ₹2,880
Annual savingsApprox. ₹34,560
Bill reductionUp to 90%

At an electricity rate of ₹8 per unit, a household using 400 units would pay around ₹3,200 per month before solar. If the 3 kW system generates around 360 units, only about 40 units would need to come from the grid, bringing the energy cost down to approximately ₹320 per month.

Example — 5kW Solar System

The decision should ultimately come down to net investment versus expected lifetime electricity savings, not simply whether solar is popular. 

Solar System Payback Period in India

The payback period tells you how long your solar savings will take to recover the initial investment. Before choosing an installer, compare quotations on a like-for-like basis. 

The Formula

Payback period = Net investment ÷ Annual electricity savings

Using the earlier 3kW example: 

₹1,57,000 ÷ ₹34,560 ≈ 4.5 years 

However, there is no single payback period that applies to every solar installation. 

Your actual payback depends on:

  • System cost
  • Government subsidy
  • Electricity tariff
  • Annual generation
  • Electricity consumption
  • Location
  • Future tariff increases

A personalised calculation based on your electricity bill provides a more useful estimate than a universal ROI claim

Based on Appliances

Fans, lights, televisions and refrigerators create relatively moderate loads. Air conditioners, geysers, water pumps, induction cooktops and EV charging can increase electricity consumption substantially.

Instead of counting appliances alone, check your electricity bills over the previous 12 months to understand actual usage.

What If Your Consumption Increases?

Factor in future requirements before finalising capacity. If you’re planning to add another AC, buy an EV or increase household occupancy, your future electricity consumption may be considerably higher than it is today.

How Much Roof Space Do You Need for Solar?

A simple planning estimate is around 80–100 sq. ft. of usable roof area per kW, although modern high-wattage panels and system design can change the requirement. 

System sizeApprox. roof space
1kW80–100 sq. ft.
2kW160–200 sq. ft.
3kW240–300 sq. ft.
5kW400–500 sq. ft.
10kW800–1,000 sq. ft.

The usable area must also account for shading, water tanks, parapet walls, panel spacing, maintenance access and other rooftop obstructions. 

Which Solar Panel Technology Is Best for Your Home?

For most residential buyers today, the practical comparison is between Mono PERC, TOPCon and, in suitable applications, bifacial panels. 

Mono PERC

Mono PERC offers a good balance between cost and efficiency and remains suitable for homeowners who want reliable performance without paying for the newest technology.

TOPCon

TOPCon offers higher efficiency and improved long-term performance. It is particularly useful where roof space is limited and maximising generation from the available area matters.

Bifacial

Bifacial panels can generate electricity from both sides, but their additional benefit depends heavily on mounting height, surface reflectivity and installation design.

The real question

TOPCon vs Mono PERC — is the higher price worth it?

TOPCon can justify its higher price when roof space is limited or maximum lifetime generation is the priority. If adequate roof space is available and the price difference is substantial, Mono PERC may still provide better value.

Compare lifetime generation and system cost rather than choosing solely because one technology is newer.

On-Grid vs Hybrid vs Off-Grid Solar Systems

SystemBatteryWorks during grid outageRelative costBest for
On-grid No* ₹2.30–₹2.40 lakhElectricity bill savings
Hybrid ₹3–₹5 lakhSavings + backup
Off-grid ₹3–₹5 lakh+Areas with unreliable/no grid

*A standard on-grid system shuts down during a power cut for anti-islanding safety, even when the sun is shining.

For most urban homes focused primarily on reducing electricity bills, an on-grid system is usually the simplest option. Hybrid and off-grid systems cost more because battery storage is required. 

How to Compare Solar Installation Quotes

Before choosing an installer, compare quotations on a like-for-like basis. 

Compare the Same Capacity

Don’t compare a 3kW system with a 3.3kW or 4kW system solely by final price. 

Check Panel Specifications

Compare technology, wattage, efficiency, manufacturer and warranties. 

Compare Inverters and Structures

Check inverter capacity and warranty along with the material and specifications of the mounting structure. 

Check What Installation Includes

Confirm whether civil work, wiring, earthing, safety equipment and commissioning are included. 

Compare Warranties

Separate the panel performance warranty from product, inverter, structure and workmanship warranties. 

Check Subsidy and Net-Metering Scope

Confirm what assistance the installer provides and what remains your responsibility. 

Check After-Sales Support

Ask who handles faults, monitoring and warranty claims after installation. 

Finally, ask for an all-inclusive price so that additional charges don’t appear after you’ve selected the installer. 

Solar System Price Trends in India 2026

The solar market in 2026 is being shaped by technology upgrades, domestic manufacturing and changing compliance requirements. 

Higher Adoption of TOPCon

The market continues to shift towards higher-efficiency technologies such as TOPCon as manufacturers expand production and buyers prioritise greater output from limited roof space. 

Growth in Domestic Manufacturing

India continues to expand domestic module and cell manufacturing capacity. This is particularly important as government programmes strengthen requirements around approved and domestically produced equipment. 

DCR and ALMM Requirements

ALMM remains an important part of the solar procurement framework. MNRE’s List-I covers approved module models and manufacturers, while List-II for solar PV cells has also become relevant under the evolving 2026 framework. 

In July 2026, the government also provided a limited exemption window for certain net-metering and open-access projects from ALMM List-II cell requirements until 31 December 2026, rather than providing a blanket extension. 

Government Support Continues

PM Surya Ghar remains a major driver of residential rooftop adoption. By 22 July 2026, nearly 39.72 lakh rooftop systems had been installed under the scheme, benefiting more than 48 lakh households. 

Should You Buy Now or Wait?

Waiting purely for panel prices to fall can be misleading because modules are only one part of the complete installation cost. If your roof is suitable, electricity consumption is high and the economics work at today’s price, delaying installation also means delaying electricity savings. 

Who Should Install a Solar System?

Solar delivers the greatest value where electricity consumption and available roof space justify the investment. 

UserSuitable systemPrimary benefit
HomeownersOn-grid rooftopLower electricity bills
Large homes3–10kWHigher savings
OfficesCommercial rooftopDaytime consumption
FactoriesLarge rooftopHigh energy offset
SchoolsRooftopDaytime generation
HotelsCommercial solarHigh electricity usage
