1kW, 3kW, 5kW & 10kW Solar Panel Cost in India

If you are planning to install solar panels for your home or business, one of the first questions is how much solar panels cost in India in 2026.

The answer depends on the system capacity, solar panel technology, inverter, mounting structure, installation requirements and location. A 1kW solar system will naturally cost much less than a 10kW system, while high-efficiency technologies such as N-Type TOPCon can have a different price from conventional modules.

For residential consumers, government subsidy can also significantly reduce the initial cost. Under PM Surya Ghar Muft Bijli Yojana, eligible residential consumers can receive Central Financial Assistance of up to ₹78,000.

In this guide, we explain the latest solar panel price in India 2026, including the cost of 1kW, 3kW, 5kW and 10kW solar systems, subsidy, panel price per watt and factors that affect the final installation price.

Solar Panel Price in India 2026

The price of a complete solar rooftop system varies from one project to another. As a general market estimate, the following ranges can be used for planning:

Important: These are indicative prices for planning purposes, not fixed quotations. The actual price can change depending on panel technology, brand, inverter, structure, roof type, location, installation complexity and other project requirements. Current market guides show similar broad ranges for residential rooftop systems.

*Central subsidy applies to eligible residential consumers under the applicable PM Surya Ghar rules.

**The Central subsidy is capped at ₹78,000 for eligible residential systems of 3kW and above; installing 5kW or 10kW does not increase the Central subsidy beyond this cap.

1kW Solar Panel Price in India 2026

A 1kW solar system is generally suitable for households with relatively low electricity consumption.

1kW Solar System Cost

The approximate complete system cost can be around:

₹60,000 to ₹80,000 before subsidy

For an eligible residential consumer: Central subsidy = ₹30,000

So, the approximate effective cost can be: ₹30,000 to ₹50,000 after Central subsidy

A 1kW solar system generally requires around 80–100 sq. ft. of shadow-free rooftop space, depending on the panel size and installation layout.

Who Should Consider a 1kW System?

A 1kW system may be suitable for a small home with basic electricity requirements such as:

• LED lights
• Fans
• Television
• Refrigerator
• Small appliances

The actual system size should be selected according to your electricity consumption rather than subsidy alone.

A 3kW solar system is one of the most popular choices for residential rooftop installations.

3kW Solar System Cost

Approximate price before subsidy: ₹1.70 lakh to ₹2.10 lakh

Central subsidy: ₹78,000

Approximate cost after Central subsidy: ₹92,000 to ₹1.32 lakh

The final price can be higher or lower depending on the panel technology, inverter, structure and installation requirements.

3kW Solar System Roof Area

A 3kW system generally needs around: 240–300 sq. ft.

of suitable shadow-free rooftop space.

How Much Electricity Can 3kW Generate?

Solar generation varies by location, weather, shading, orientation and system losses. As a broad planning estimate, a 3kW system can generate several hundred units of electricity per month under suitable conditions.

Actual generation should be estimated using the site's solar irradiation and system design.

5kW Solar Panel Price in India 2026

A 5kW solar system is suitable for larger homes and properties with higher electricity consumption.

5kW Solar System Cost

Approximate price before subsidy: ₹2.80 lakh to ₹3.40 lakh

Therefore, the approximate cost after Central subsidy can be around: ₹4.42 lakh to ₹5.72 lakh

A 10kW system can require around 800–1,000 sq. ft. of suitable installation area, depending on module wattage and layout.

For commercial and industrial applications, subsidy rules are different, so businesses should not assume that the residential ₹78,000 subsidy applies.

Solar Panel Price Per Watt in India

Many buyers compare solar panels using ₹ per watt.

The price per watt depends on technology, wattage, efficiency, manufacturer and market conditions.

Indicative 2026 module-level ranges can look like:

These are module-level indicative prices, not the price of a complete rooftop solar system. Complete system cost also includes inverter, structure, cables, protection equipment, installation and other components. Current market guides likewise show technology-dependent module pricing.

Solar Panel Price vs Solar System Price

These two terms are often confused.

Solar Panel Price

This means the cost of the solar modules only.

Solar System Price

This generally includes:

• Solar panels
• Solar inverter
• Mounting structure
• DC and AC cables
• Protection equipment
• Earthing
• Installation
• Testing and commissioning
• Other required accessories

Therefore, if someone quotes you a very low solar panel price per watt, it does not necessarily mean that the complete solar installation will cost the same amount.

Always ask for a complete system quotation.

What Is Included in a Complete Rooftop Solar System?

A good solar quotation should clearly mention the major components.

1. Solar Panels: Solar panels convert sunlight into DC electricity.
2. Solar Inverter: The inverter converts the DC electricity produced by solar panels into AC electricity used by household appliances.
3. Mounting Structure: The structure holds the solar panels securely on the rooftop.
4. Solar Cables: Proper DC and AC cables are required for safe electricity transmission.
5. Protection Equipment: Depending on the system design, appropriate protection devices are used to protect the installation.
6. Earthing: Proper earthing is an important part of electrical safety.
7. Installation: Installation charges depend on roof type, height, accessibility and project complexity.
8. Metering and DISCOM Work: For grid-connected systems, applicable metering and DISCOM procedures may also form part of the project.

Solar Panel Price by Technology

The technology you select can affect both price and performance.

Mono PERC Solar Panels

Mono PERC solar panels have been widely used for residential and commercial applications.

They offer a good combination of efficiency and price and remain a practical option for many projects.

N-Type TOPCon Solar Panels

N-Type TOPCon Solar is a newer high-efficiency solar technology.

It offers advantages such as:

• Higher efficiency
• Good performance at elevated temperatures
• Lower degradation characteristics
• High power output

TOPCon can be particularly useful where rooftop space is limited.

Bifacial Solar Panels

Bifacial solar panels can generate electricity from both the front and rear sides of the module.

The additional rear-side generation depends on factors such as:

• Roof or ground reflectivity
• Panel height
• Mounting structure
• Installation environment
• Shading

N-Type TOPCon Bifacial Solar Panels

These modules combine N-Type TOPCon technology with bifacial generation.

They are increasingly being considered for modern solar installations where higher efficiency and additional energy yield are important.

On-Grid, Off-Grid or Hybrid Solar: Which Costs More?

Your solar system type also affects the total price.

On-Grid Solar

An on-grid solar system works with the electricity grid and normally does not require batteries. It is generally the most economical option for reducing electricity bills.

Hybrid Solar

A hybrid solar system combines solar, grid electricity and battery storage. It costs more because batteries are included.

Off-Grid Solar

An off-grid solar system is designed to work without depending on the electricity grid and requires battery storage.

Solar Panel Subsidy in India 2026

Government subsidy can reduce the upfront cost of a residential rooftop solar system.

Under PM Surya Ghar, the Central Financial Assistance structure provides:

• ₹30,000 per kW for the first 2kW
• ₹18,000 for the additional capacity up to 3kW
• Maximum Central subsidy: ₹78,000

The subsidy is for eligible residential consumers and is linked to the applicable installation, vendor and DISCOM verification process.

The Government's PM Surya Ghar programme was launched with the objective of supporting rooftop solar installations in one crore households.

Is There Any State Subsidy on Solar Panels?

Yes, some states provide additional support, but it is not uniform across India.

This is important when calculating the final solar panel price after subsidy.

Depending on the state, additional support may be provided through:

• Additional capital subsidy
• State financial assistance
• Generation-based incentives
• SGST-related benefits
• Special support for selected consumer categories

Therefore, your final solar cost can be:

System Price − Central Subsidy − Applicable State Benefit

However, state benefits change according to state policies and eligibility. Always verify the current state/DISCOM rules before including a state subsidy in your final calculation.

How Much Roof Space Is Required for Solar Panels?

Roof area is another important factor when choosing a solar system.

The exact area depends on the dimensions and wattage of the panels, mounting arrangement and required access space.

How Many Solar Panels Are Needed?

The number of panels depends on the wattage of the selected module.

For example, with a 550W solar panel:

• 1kW → around 2 panels
• 3kW → around 6 panels
• 5kW → around 10 panels
• 10kW → around 19 panels

The exact number depends on the final system capacity and module wattage selected.

Higher-wattage modules can reduce the number of panels required for the same system capacity.

How Much Electricity Can a Solar Panel System Generate?

Solar generation depends on:

• Location
• Sunlight
• Weather
• Panel orientation
• Tilt angle
• Shading
• Temperature
• System losses
• Cleaning and maintenance

A commonly used planning estimate for Indian rooftop solar is around 3–5 units per kW per day on average, but actual generation can vary significantly by location and season.

For example, a 3kW system could potentially generate roughly 9–15 units per day under suitable conditions.

This is only an estimate; a site-specific solar assessment gives a more reliable figure.

What Factors Affect Solar Panel Price in India?

The final quotation can vary considerably because of several factors.

1. Solar Panel Technology: TOPCon and bifacial modules may have different prices from conventional Mono PERC modules.
2. Panel Wattage: Higher-wattage modules can reduce the number of panels needed.
3. Inverter: The inverter is a major part of the total system cost.
4. Roof Structure: A standard RCC roof may have a different installation cost from a metal roof or elevated structure.
5. Installation Location: Transportation and labour costs vary by city and state.
6. System Type: On-grid, hybrid and off-grid systems have different component requirements.
7. Warranty: A system with better product and performance warranties may cost more initially but can offer better long-term value.
8. Installation Quality: The quality of structure, wiring, earthing and protection equipment also affects the total price.

How to Choose the Right Solar System Size?

Don't choose a solar system only because of its price.

First check your electricity consumption.

1kW: Suitable for smaller electricity requirements.

3kW: A popular choice for many residential homes.

5kW: Suitable for larger homes with higher electricity consumption.

10kW: Suitable for large homes, institutions and certain higher-load applications, subject to the applicable connection and regulatory requirements.

The best system is the one that matches your electricity consumption, roof area and budget.

How to Reduce the Cost of Solar Installation?

You don't necessarily need to buy the cheapest solar panel.

Instead: Compare Complete Quotations

Ask different vendors for a detailed quotation.

Compare ₹/W

Check the effective cost per watt, but make sure you're comparing similar system specifications.

Check What Is Included

Make sure the quote clearly mentions:

• Panels
• Inverter
• Structure
• Cables
• Protection equipment
• Installation
• Earthing
• Metering-related work

Check Subsidy Eligibility

Confirm whether the project qualifies for Central and applicable state support.

Compare Warranty

Don't ignore product and performance warranty while comparing prices.

Is Solar Worth Buying in 2026?

For many households and businesses, rooftop solar can be a useful long-term investment.

The biggest advantage is that solar electricity can reduce the amount of electricity purchased from the grid.

Your actual savings depend on:

• System cost
• Solar generation
• Electricity tariff
• Self-consumption
• Net-metering rules
• Subsidy
• Maintenance

Therefore, instead of asking only “What is the cheapest solar panel?”, it is better to ask:

“Which solar system will provide the best value over its lifetime?”
