What’s the 3 kW Solar Panel Price in Delhi with Subsidy in 2025? ROI Calculations Included

The solar panel price in Delhi with subsidy for on-grid solar systems reduces from ~Rs. 2.15 lakh* to ~Rs. 1.07 lakh*. The massive drop in the solar panel price in Delhi by Rs. 1.08 lakh is the result of a state subsidy of Rs. 30,000 and a central subsidy of Rs. 78,000 for a 3 kW grid-connected solar system. Delhi is one of the very few Indian states that offers a state subsidy on top of the central government’s subsidy under the PM Surya Ghar Muft Bijli Yojana.

*Please note: The above-mentioned 3 kW solar panel price is indicative as of 25th October 2025 for the SolarSquare Blue 6ft variant. The final solar panel cost in Delhi depends on your DISCOM charges, 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. 

In recent months, the Air Quality Index in Delhi has gone from very poor to severe. Installing a rooftop solar panel system for homes can help address the state’s worsening air quality, as a 3 kW rooftop solar system can offset 77,616 kg of carbon dioxide over 25 years. Moreover, no other form of investment can offer a return on investment of ~6.6 times in Delhi, except for a 3 kW on-grid solar system.

If your home’s annual electricity consumption is 4,200 to 4,350 units and you also have one 1.5-ton air conditioner to run, a 3 kW solar system with high-efficiency half-cut solar panels is an ideal fit.

In this blog, we’ve explained the 3 kW solar panel price in Delhi with subsidy, the solar savings you can expect over 25 years, and the total subsidy you can get. We’ve also provided a detailed breakdown of the cost of solar panels in Delhi for different-capacity solar systems, the ROI you can expect, and the benefits of siding with on-grid systems over off-grid and hybrid solar photovoltaic systems. 

TL;DR Summary Box: Is Solar Subsidy Available in Delhi?

Delhi is among a handful of states in India that offer their residents a special state subsidy in addition to the central government subsidy under the PM Surya Ghar Muft Bijli Yojana. The maximum state subsidy is capped at Rs. 30,000, and 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.

Why is 2025 the Best Time for Solar Panel Installation in Delhi?

Right now, the government is trying to meet its target of solarizing one crore homes under the Surya Ghar Yojana and, at the same time, inspire homeowners to go solar and tackle energy dependence and pollution right from their rooftops. Once one crore homes install solar, the subsidy under the PM Surya Ghar Muft Bijli Yojana might no longer be offered. 

Here’s why now is the best time to go solar in Delhi: 

• You can install rooftop solar systems at extremely cheap rates. Subsidies will not be offered forever. 
• Air pollution in Delhi is posing serious health risks. Installing something as small as a 3 kW solar system can offset 77,616 kg of carbon dioxide over 25 years. 

Just by changing your energy habits from fossil fuels to renewable solar energy, you can singlehandedly make your state breathe again!

What are the Types of 3 KW Solar Systems and Their Prices?

The biggest challenge homeowners face in Delhi when installing solar is choosing between on-grid, off-grid, and hybrid systems. To clear the air once and for all, keep in mind that on-grid solar systems offer the best ROI and are the cheapest of the three PV system types. They do not require expensive lithium batteries to store solar energy because they can draw electricity from the grid to keep the load running at night.

Here’s a tabulated snapshot of how much these systems cost:

Is 3 kW Enough to Run a House in Delhi?

A 3 kW solar system with high-efficiency bifacial solar panels can generate 4,200 to 4,350 units of electricity yearly, which is sufficient to power all common household appliances in a 2-3 BHK home. A well-maintained solar system of this capacity can even power one 1.5-ton air conditioner. 

Let’s check out all the appliances that a 3 kW solar system can run:

• 1 1.5ton AC
• 4-5 fans
• 3-4 LED bulbs
• 1-2 LED tube lights
• 1 refrigerator
• 1 LED TV
• 1 washing machine
• Common kitchen appliances, including a mixer/grinder and induction cookers. 

What are the Benefits of Installing a 3 kW On-grid Rooftop Solar System in Delhi?

Installing a 3 kW solar system in Delhi can offer a ~6.6x return on the initial investment, save tens of lakhs of rupees on electricity bills, and help tackle air pollution. 

Let’s check out all the benefits in detail:

• It can make the air in Delhi breathable: A 3 kW rooftop solar system can prevent over 77,616 kilograms of carbon emissions over 25 years. That’s the same as what 118 fully grown trees would absorb from the air in the same amount of time. While not burning crackers might or might not be the solution to make Delhi’s air breathable again, installing a solar system surely is!
• It has a quick payback period and high ROI: The system pays for itself in 3 to 5 years by generating free electricity from nothing but solar radiation. Moreover, you receive a return on investment of ~6.6 times. 
• It reduces electricity bills by 90% or more: Since the system generates free electricity for 25+ years, you can forget about paying hefty bills, as your reliance on expensive grid electricity will plummet.

Why Choose SolarSquare’s 3.24 kW and 3.78 kW Solar Systems?

Most people simply assume a 3 kW solar system means exactly 3,000 watts. In reality, that’s hard to build using high-efficiency 540W solar panels. The calculation shows it clearly: 3,000 ÷ 540 = 5.55 panels.

Since no one can install half a panel, most installers stop at 5. But that gives you only 2.7 kW, which is a downsized system that may fall short of your actual energy needs.

At SolarSquare, we take things a notch higher by designing 3.24 kW and 3.78 kW solar systems rather than downsizing.

• Our 3.24 kW system uses 6 full panels for those who want proper 3 kW power generation, not a compromise.
• Our 3.78 kW system uses 7 panels, which is ideal for homes that need just a little more power but not a full jump to 4 kW.

Conclusion

The 3 kW solar panel price in Delhi with subsidy is just ~Rs. 1.07 lakh*. The Rs. 1.08 lakh price reduction from ~Rs. 2.15 lakh* without subsidy to ~Rs. 1.07 lakh* with a subsidy is the result of financial assistance from both the state government and the central government. 2025 is the best time to go solar because government financial assistance will not last forever. 

*Please note: The above-mentioned 3 kW solar panel price is indicative as of 25th October 2025 for the SolarSquare Blue 6ft variant. The final solar panel cost in Delhi depends on your DISCOM charges, 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.

Q2. What is the lifespan of a 3 kW solar panel?

Ans. A solar panel that’s cleaned from time to time by professionals can last for 25 years easily. Such panels produce electricity at 80% efficiency even after 25 years.

Q3. How much electricity is generated by a 3 kW solar panel per day?

Ans. A 3 kW solar system can generate between 4,200 and 4,350 units per year, which averages out to about 11.50 to 12 units daily across 365 days. However, you need to understand that solar output isn’t linear. Some days are sunnier while others are cloudy. Output drops during the monsoons and goes up in the summer. That’s perfectly normal! As long as your system is properly maintained, these ups and downs balance out, and the promised annual savings hold.
