What’s the 4 kW Solar Panel Price in Lucknow with Subsidy? Explore ROI and Steps to Apply For a Subsidy

The 4 kW solar panel price in Lucknow with subsidy for on-grid solar systems is ~Rs. 1.42 lakh* in 2025. This is cheaper than most other Indian states because the Uttar Pradesh state government offers its residents an additional state subsidy, increasing the total financial assistance offered to homeowners for installing a grid-connected solar system.

*Please note: The above-mentioned 4 kW solar panel price in Lucknow with subsidy for on-grid solar systems is indicative as of 22nd November 2025 for the SolarSquare Blue 6ft variant. The final 4 kW on-grid solar system price in Lucknow 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. 

Unlike most states with a central subsidy of Rs. 78,000 on a 4 kW system, the total solar subsidy in Lucknow (the central subsidy + the state subsidy) for a 4 kW grid-connected solar system is Rs. 1.08 lakh, because of the additional financial assistance of Rs. 30,000 from the state government. This high subsidy assistance makes rooftop solar installation in Lucknow extremely affordable.

Investing less than a lakh and a half in a 4 kW solar system in Lucknow offers massive savings of ~Rs. 11.70 lakh* over 25 years of the system’s life. That’s an exceptionally high ROI of ~8.2x. You can try investing the same amount in gold, mutual funds, or FDs over the same 25-year period, but the ROI will not be as high as that from a 4 kW on-grid rooftop solar panel system for homes. 

*Please note: When calculating savings, we have considered an annual tariff escalation of 3% and an annual plant degradation rate of 1%. The actual final savings from a 4 kW solar system depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.

Besides offering a high ROI, installing a 4 kW on-grid rooftop solar system also reduces electricity bills by 90% or more and offsets ~1,04,000 kg of carbon dioxide over 25 years.

How to Apply for a Solar Subsidy in Lucknow?

Homeowners in Lucknow can apply for the rooftop solar subsidy offered by the state and the central governments through a single application filed on the PM Surya Ghar Muft Bijli Yojana National Portal. The Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA) handles the disbursement of state subsidies. 

UPNEDA views the same information you provide on the Surya Ghar Portal to process the state subsidy. You do not handle two applications. Your documents and details only need to be uploaded once, and both agencies act based on that submission.

Here are the steps you can follow to register your account on the PM Surya Ghar Portal to claim your subsidy amount in Lucknow:

• Step 1 – Open the official portal: Go to the PM Surya Ghar Muft Bijli Yojana National Portal and select the option labelled “Apply for Rooftop Solar.”
• Step 2 – Create your consumer profile on the portal: Pick your state, district, and DISCOM from the drop-down menus. Register by entering your Customer Account Number.
• Step 3 – Fill out the rooftop solar form: Provide your personal details and enter the numbers from your most recent electricity bill.
• Step 4 – Add banking information: Upload the documents listed on the portal, enter your bank details, and attach a cancelled cheque. Be very careful with these details, as the bank account you register in this step is where the subsidy will be directly sent upon approval.
• Step 5 – Select an empanelled installer: Choose an installation company, such as SolarSquare, from the DISCOM-approved list shown on the portal.
• Step 6 – Upload the signed agreement: Sign the agreement you receive from your chosen installer and upload the signed file to the National Portal.
• Step 7 – Net meter is installed: After your PV system is installed, the DISCOM places a bi-directional or smart meter that measures electricity exported to and imported from the grid.
• Step 8 – Get the commissioning certificate: Once the system is inspected and found to be working, the DISCOM issues the Solar Commissioning Certificate.
• Step 9 – File your subsidy claim: Log in to the National Portal again and upload the Commissioning Certificate to submit your subsidy claim.
• Step 10 – Receive the subsidy: After the authorities approve your claim, the central and state subsidy amounts are deposited into your bank account within 30 days.

What are the Types of 4 kW Solar Systems and Their Prices in Lucknow?

On-grid, off-grid, and hybrid are the three primary photovoltaic systems homeowners usually choose between when going solar. On-grid PV systems are most recommended in areas with a reliable grid supply and no power cuts. On the other hand, off-grid and hybrid solar systems are better suited to areas with frequent, prolonged power outages. 

Before we take you through the differences between the three types and their working, let’s check out their prices in Lucknow in 2025:

Is 4 kW Enough to Run a House in Lucknow?

A 4 kW rooftop solar system generates 5,600 to 5,800 units of electricity per year, enough to meet all energy requirements for a 3 BHK home in Lucknow. It can power multiple home appliances, including one or two 1.5-ton air conditioners.

Here’s a list of common home appliances you can run on a 4 kW solar system in Lucknow:

• AC
• Washing machine
• Refrigerator
• TV
• Home lighting system and fans
• Geyser
• All common kitchen appliances

What are the Benefits of installing a 4 kW On-Grid Rooftop Solar System?

A 4 kW on-grid solar system can generate enough electricity for a 3 BHK home, deflating the bills by 90% or more. The best part? When cleaned and maintained by professionals, the system continues to generate free solar electricity for 25 years. It results in massive savings over time.

Let’s have a look at the benefits of installing a 4 kW on-grid solar system in Lucknow closely:

• It reduces reliance on expensive grid supply and deflates electricity bills: Since it’s a powerful PV device, it generates enough electricity to meet the entire household’s needs. This reduces the need for expensive grid electricity. As a result, electricity bills get slashed by 90% or more.
• It saves tens of lakhs of rupees: With near-zero bills for 25 years, you’ll save ~Rs. 11.70 lakh* from a 4 kW solar system in Lucknow with an upfront investment of just ~Rs. 1.42 lakh*. That’s an ROI of ~8.2x.
• It tackles air pollution right from your roof: A 4 kW solar system has the same environmental impact as that of 157 full-grown trees, because, just as the trees would, the PV system offsets ~1,04,000 kg of carbon emissions over its 25-year lifespan.

The final 4 kW solar system price in Lucknow 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, when calculating savings, we have considered an annual tariff escalation of 3% and an annual plant degradation rate of 1%. The actual final savings from a 4 kW solar system depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.

Why Choose SolarSquare’s 4.32 kW and 4.86 kW Solar Systems?

Installing a 4 kW solar system using modern 540Wp solar panels would mathematically require ~7.40 panels (4,000 ÷ 540). Since only whole panels can be installed, the options are 7 or 8 panels.

Most installers use 7 solar panels, but the resulting system is not a true 4 kW solar system. Instead, it’s a downsized 3.78 kW system. This downsized system will not generate enough power to meet all the energy needs of a home that requires 4 kW of capacity. The result? Bills will not be as low as they should be, and the savings will also shrink. 

That’s why SolarSquare designed a 4.32 kW system using 8 540-watt solar panels and a 4.86 kW solar system using 9 540-watt solar panels. We do not downsize your solar system, which, in turn, ensures that you get near-zero bills and massive savings. 

Conclusion 

The 4 kW solar panel price in Lucknow with subsidy for on-grid solar systems is ~Rs. 1.42 lakh*. When you use high-efficiency solar panels, a 4 kW solar system is enough to take care of all your home’s energy requirements, considering your annual power consumption is 5,600 to 5,800 units. Moreover, spending just ~Rs. 1.42 lakh* to install a 4 kW solar system in Lucknow can save ~Rs. 11.70 lakh* over 25 years.
