How to Apply for a Solar Subsidy in Lucknow?

The PM Surya Ghar Muft Bijli Yojana National Portal serves as the single point of entry for the subsidy process. When you submit your rooftop solar application on the portal, the details you enter are used in two ways. They are checked for the central subsidy under the PM Surya Ghar Muft Bijli Yojana and also shared with the Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA) for the state-level subsidy.

You can follow these steps to complete the subsidy process in Lucknow:

• Step 1 – Open the official portal: Go to the PM Surya Ghar Muft Bijli Yojana National Portal and click the Apply for Rooftop Solar option.
• Step 2 – Create your consumer profile on the portal: Choose your state, your district, and your DISCOM. Then enter your Customer Account Number to create your profile.
• Step 3 – Fill out the rooftop solar form: Enter your personal details and enter the figures from your most recent electricity bill.
• Step 4 – Add banking information: Upload the documents requested by the portal, provide your bank account details, and upload a cancelled cheque for verification.
• Step 5 – Select an empanelled installer: Pick an installation company from the list approved by your DISCOM for rooftop solar projects.
• Step 6 – Upload the signed agreement: Sign the agreement you receive from your chosen installer, then upload the signed copy to the National Portal.
• Step 7 – Net meter is installed: After the solar system is installed, your DISCOM fits a bi-directional or smart meter that records both the electricity you draw from the grid and the electricity you send back.
• Step 8 – Get the commissioning certificate: Once the solar plant has been checked and confirmed operational, your DISCOM issues the Solar Commissioning Certificate.
• Step 9 – File your subsidy claim: Log in to the National Portal and submit the Commissioning Certificate to process your subsidy claim.
• Step 10 – Receive the subsidy: After your claim is approved, the sanctioned subsidy amount is credited directly to your bank account within 30 days.

IMPORTANT: Because UPNEDA reads your information directly from the portal, you are not asked to fill out a separate state subsidy form. Provide correct information and upload the right documents. After your system is installed and the net meter is in place, UPNEDA reviews the data on the portal and confirms that the installation matches what was applied for. Upon successful verification, the state subsidy is approved and transferred directly to your bank account, along with the PM Surya Ghar subsidy.

What are the Types of 3 kW Solar Systems and Their Prices in Lucknow?

On-grid, off-grid, and hybrid solar systems are the three main types of PV systems customers choose from based on their requirements and budget. On-grid systems are the most affordable and are suggested in areas where the grid is reliable and power cuts are not an issue. 

On the other hand, off-grid or hybrid solar systems are recommended in areas with frequent power outages. That’s because these systems store solar energy in lead-acid or lithium batteries that can provide backup power.

Before we take you through the primary differences between the three, let’s check out how much they cost:

Top Factors that Affect the Cost of a 3 kW Solar System in Lucknow

The cost of a 3 kW solar system in Lucknow can vary based on the type of solar system, panel, and inverter you choose. It will also be influenced by the DISCOM’s metering charges, the AMC contract you choose, and the height of the solar mounting structure. 

Let’s check out how each of these factors impacts the final cost of a 3 kW solar panel system in Lucknow:

• The type of solar system you choose: On-grid systems remain the most affordable because they do not need battery storage. Off-grid and hybrid systems include batteries, so you can run appliances during power cuts, which naturally increases the total price. The choice will ultimately boil down to how reliable your grid supply is.
• The type of solar panel: Higher-efficiency panels cost more. Half-cut mono-PERC and TOPCon panels cost more than older polycrystalline models, but they generate more electricity and require fewer units to reach the same capacity. 
• Solar inverter type: String inverters are far more economical than microinverters. Microinverters make sense only when the roof has shading issues during peak sunshine hours.
• Height of the solar mounting structure: Taller structures need more steel, more labor, and more fabrication time. Each of these adds to the installation cost.
• DISCOM application and net metering charges: Your electricity provider sets its own fees for reviewing applications, inspecting the system, and installing the net meter. These charges differ from one DISCOM to another, even within Lucknow.
• Annual maintenance plan selection (AMC): Signing up for an annual maintenance contract increases the upfront cost slightly, but it covers panel cleaning, general check-ups, and inverter servicing. This reduces long-term performance losses and helps prevent avoidable breakdowns, saving money in the long run.
• Roof design, slope, and shadow impact: Flat concrete roofs cost the least to install on. Tiled, sloped, or shaded rooftops often require custom mounting or additional structural assessment, which increases the final 3 kW solar system price in Lucknow.

Is 3 kW Enough to Run a House in Lucknow?

A 3 kW solar system in Lucknow can easily power a 2-3 BHK home with an annual electricity consumption of 4,200 to 4,350 units. If that sounds like your annual power requirements, here’s a list of appliances you can run in your home using a 3 kW on-grid solar system:

• One 1.5-ton air conditioner
• 1 refrigerator
• 1 LED TV
• 1 washing machine
• 3-4 LED bulbs
• 1-2 LED tube lights
• 4-5 ceiling fans
• 1 mixer grinder
• 1 induction cooktop 

What are the Benefits of a 3 kW On-Grid Rooftop Solar System in Lucknow?

Installing a 3 kW on-grid solar system with high-efficiency solar panels can make your electricity bills near zero, as the system will generate enough electricity to power all your energy needs. This will reduce your reliance on grid electricity, which isn’t just expensive but also polluting. 

Let’s have a look at the multiple benefits a 3 kW on-grid solar system offers:

• It is the most affordable solar system type: An on-grid solar system does not require batteries to store solar energy. As a result, it’s the most affordable option, making it an ideal investment in areas where power outages are not common.
• It reduces hefty bills: When sized correctly, an on-grid solar system can meet a home’s energy needs. This reduces the reliance on grid electricity, deflating the bills by 90% or more. 
• It reduces your carbon footprint: A 3 kW solar system can offset ~78,000 kg of carbon dioxide from the atmosphere in 25 years, which is the same amount of carbon 118 full-grown trees would absorb in the same time span. Hence, a 3 kW solar system can tackle air pollution right from your rooftop, making the air cleaner.

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

When you try to size a 3 kW solar system with 540-watt panels, the numbers don’t line up neatly. The calculation comes to 5.55 panels (3,000 ÷ 540), and since panels cannot be divided, you are forced to choose a whole number.

If you select only 5 panels, the system you end up with is 2.70 kW. A system of this size cannot cover the full electricity demand of a home that needs 3 kW, so your monthly bill will still be noticeable, and your solar savings will stay below what a true 3 kW system can deliver.

To avoid this shortfall, SolarSquare designs its 3 kW category with 6 panels, creating a 3.24 kW system. This ensures stronger power generation and gives you a real chance at reaching zero bills. 

For households that need a little more output but do not require a full 4 kW PV system, the 3.78 kW option features 7 panels and provides extra capacity without oversizing.

Conclusion

The 3 kW solar panel price in Lucknow with subsidy for on-grid solar systems is ~Rs. 92,000*. It’s a worthwhile investment because this same system will save ~Rs. 8.77 lakh* over 25 years, offering an ROI of ~9.5x.
