How Much is the Solar Subsidy in Karnataka in 2025?

The Karnataka state government, unlike the UP and Delhi governments, does not offer any special state solar subsidy. However, it does not mean that homeowners have to purchase a rooftop solar system in Karnataka at full price. You can still benefit from the subsidy offered by the central government under the PM Surya Ghar Muft Bijli Yojana.

The maximum subsidy under the PM Surya Ghar Muft Bijli Yojana is capped at Rs. 78,000 for solar systems with a capacity of 3 kW or higher. 

Let’s check out the subsidy details as listed on the government website:

• Solar subsidy in Karnataka for 1-2 kW solar systems: Rs. 30,000 per kilowatt
• Solar subsidy in Karnataka for additional capacity over and above 2 kW up to 3 kW: Rs. 18,000
• Solar subsidy in Karnataka for 3 kW or higher capacity: Rs. 78,000

What are the Types of 2 kW Solar Systems and Their Prices in Karnataka?

Three types of solar systems you should be aware of are on-grid, off-grid, and hybrid solar energy systems. Of the three types, on-grid systems are the cheapest and most preferred for both residential and commercial rooftop systems. 

Before we explore how they work, let’s find out their estimated cost in Karnataka:

*Please note: The above-mentioned 2 kW solar panel price in Karnataka with subsidy for on-grid solar systems is indicative as of 15th October 2025 for the SolarSquare Blue 6ft variant in Bangalore. The final 2-kilowatt solar panel price depends on your DISCOM charges, city, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change. Additionally, the solar plate price in Karnataka for off-grid and hybrid solar systems is based on standard market estimates and may vary from the stated range depending on the type of batteries, panels, brand, and inverters you choose. SolarSquare does not sell or install hybrid or off-grid solar systems. We exclusively install on-grid rooftop solar systems for homes, housing societies, commercial buildings, and industrial facilities.  

Now, let’s understand how these systems work and differ from each other:

• On-grid solar systems: These are the most affordable type of solar systems for two reasons. First, they are eligible for a subsidy. Second, they do not require expensive lithium batteries to store solar energy. If solar panels do generate excess power during the daytime, it is sent to the grid instead of being stored in a battery for night use. At night or wherever needed, power can be imported from the grid to keep the load running. 
• Off-grid solar systems: Since they are not connected to the grid, charging lithium batteries through a solar panel charge controller during the daytime is the only option to ensure a power supply at night. Lithium batteries are pretty expensive, and they also have to be replaced from time to time. As a result, maintaining off-grid solar systems is just as expensive as installing them.
• Hybrid solar systems: When the panel generates excess electricity during the day, it can be used to charge the lithium battery bank through an MPPT charge controller, which is usually a built-in component in the hybrid solar inverter. If the DISCOM permits solar net metering and there’s still some energy left after the batteries are charged, it can be sent to the grid. The hybrid solar system is the most expensive of the three types and is usually recommended only for large utility-scale solar power plants.

What’s the Solar Panel Price in Karnataka for Different Capacity Solar Systems?

The solar panel price in Karnataka with subsidy ranges between ~Rs. 1.35 lakh* in Bangalore for a 2 kW solar system and ~Rs. 5.55 lakh* in Bangalore for a 10 kW solar system. 

Let’s check out the solar panel prices in Karnataka before and after a subsidy in detail:

The final 2 kW solar panel price depends on your DISCOM charges, city, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change.

Is a 2 kW Solar System Enough to Power a Home in Karnataka?

A 2 kW solar system is sufficient for 1-2 BHK homes that consume 2,800-2,900 units of electricity yearly. However, keep in mind that 2 kW cannot power an air conditioner. For an AC, you need at least a 3 kW solar system.

Here’s a list of appliances that can run on a 2 kW solar system:

• 2-3 ceiling fans
• 1-2 LED bulbs
• 1-2 tube lights
• 1 refrigerator
• 1 LED TV
• 1 washing machine
• Common kitchen appliances like an induction cooktop and a mixer/grinder

What are the Benefits of installing a 2 kW On-grid Rooftop Solar System in Karnataka?

Investing money in a 2 kW on-grid solar system in Karnataka today can offer ~4.8 times the return on investment, making rooftop solar in Karnataka a smart choice for homeowners. 

Let’s check out all the benefits that these solar systems offer:

• They slash electricity bills by 90% or more: Since the solar system can meet all your energy needs, you won’t depend much on expensive grid electricity. This will slash your bills by 90% or more.
• They save tens of lakhs of rupees: Solar systems shield you from rising electricity costs year after year. With tariff hikes of 3-6% annually, avoiding grid power for 25 years can easily translate into savings worth several lakhs over the system’s lifetime.
• They reduce air pollution substantially: Installing a 2 kW solar system can prevent up to 51,744 kg of carbon dioxide emissions over 25 years. That’s the same environmental impact as planting 78 full-grown trees.

Why Choose SolarSquare’s 2.16 kW and 2.70 kW Solar Systems?

With modern solar modules that are usually 540 watts, building an exact 2 kW solar system isn’t technically possible. The math lands at 3.7 panels (2,000 ÷ 540). Since panels don’t come in fractions, a choice has to be made.

Most installers choose to round down to 3 panels, delivering a system that’s actually just 1.62 kW. That drop in capacity reduces the solar output noticeably and increases your dependency on grid power.

At SolarSquare, we don’t compromise on system size or solar savings.

• Our 2.16 kW system uses 4 panels, making sure your generation stays strong and reliable.
• Our 2.70 kW system uses 5 panels, ideal for homes that need slightly more power but don’t require a full 3 kW solar system.

These configurations are carefully designed to avoid undersizing, helping you:

• Generate more solar units per day.
• Cut down electricity bills more effectively.
• Get a faster return on your investment.

Conclusion

Thanks to the Rs. 60,000 subsidy offered by the government on a 2 kW system, the 2 kW solar panel price in Karnataka with subsidy drops from ~Rs. 1.95 lakh* to ~Rs. 1.35 lakh*. If your home consumes 2,800-2,900 units of electricity annually and you don’t need to run an air conditioner, a 2 kW solar system will be enough to meet all your power requirements, slashing your bills by 90% or more.

FAQs

Q1. How many solar panels are required for a 2 kW solar system?

Ans. Number of solar panels = solar system’s capacity (in watts) ÷ module’s capacity (in watts). If you’re using 540-watt solar panels to install a 2 kW solar system, then, based on the formula above, you will require ~4 solar panels to reach the desired system capacity.

Q2. What roof size do I need for a 2 kW solar system?

Ans. A 2 kW solar system can be installed in 200 square feet of shadow-free area of a rooftop.

Q3. Which company’s solar panel is best?

Ans. You can choose modern technology PERC or TOPCon solar panels manufactured by Rayzon, ReNew Solar, and Premier Energies.

Q4. Which type of solar panel is best for homes?

Ans. The two most advanced solar panels used nowadays are mono-PERC and TOPCon modules. These panels work well even under shadows, and their output remains consistently high at high temperatures because they have a low temperature coefficient.
