What’s the 1 kW Solar Panel Price in Delhi with Subsidy? Explore ROI and Steps to Apply For a Subsidy

The 1 kW solar panel price in Delhi with subsidy for on-grid solar systems in 2025 ranges between ~Rs. 20,000* to ~Rs. 52,500*. The cost of rooftop solar is at an all-time low in Delhi because, as of now, homeowners can receive two solar subsidies: the PM Surya Ghar subsidy offered by the central government and the subsidy offered by the Delhi government. The total subsidy on 1 kW solar systems in Delhi in 2025 is Rs. 40,000.

*Please note: The above-mentioned 1 kW solar panel price in Delhi with subsidy for on-grid solar systems has been calculated as the base price of the 5 kW and 2 kW solar systems as of 26th November 2025 for the SolarSquare Blue 6ft variant. SolarSquare does not sell 1 kW solar systems, as most Indian homes require at least a 2 kW system to become truly energy independent. The final cost of a 1 kW solar panel system 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. 

A 1 kW rooftop solar system is worthwhile only for homes with annual electricity consumption of 1,400 to 1,450 units. In reality, even small 1-2 BHK homes in Delhi consume 2,800 to 2,900 units annually, which a 2 kW solar system can generate. 

Choosing the right PV system size is extremely essential to ensure you can become truly energy independent. When sized based on your home’s annual energy consumption, an on-grid rooftop solar panel system for homes can shrink hefty electricity bills to zero or near-zero. You can expect solar savings in tens of lakhs of rupees over the system’s 25-year lifespan. For instance, a 5 kW on-grid solar system in Delhi that costs ~Rs. 1.92 lakh* with subsidy can save ~Rs. 12.94 lakh* over 25 years.

Is 1 kW Sufficient for a Home in Delhi?

A 1 kW solar system is a worthwhile investment only for homes that consume 1,400 to 1,450 units of electricity annually. In reality, even an average 1-2 BHK household would consume 2,800 to 2,900 units of electricity in a year, and that requirement cannot be met by a 1 kW solar system alone. Thus, a minimum 2 kW capacity solar system is usually required. 

While it can power normal lights, a few fans, and small kitchen appliances like an induction cooktop, a 1 kW solar system is not ideal to power heavy-load appliances like a washing machine, a TV, or even a refrigerator. 

How to Find the Right Solar System Size for Your Home in Delhi?

Choosing the right solar system size starts with understanding how much electricity your home actually uses in a year. Everything you need is already printed on your old electricity bills, and once you total those numbers, determining the system size is easy.

Here is the process to figure it out:

• Step 1 – Collect your bills for the past year: Gather all monthly bills from the last 12 months.
• Step 2 – Add the units from all the bills: Combine the unit figures from each bill to get one total number. This total represents the amount of electricity your home used over the entire year.
• Step 3 – Compare your total with the output of a 1 kW system: A 1 kW solar system generates about 1,400-1,450 kWh per year. Divide your total yearly usage by 1,400 to estimate the size of the system that can support your home.

To help you match your consumption with a suitable system size, use the chart below:

What’s the Rooftop Solar Installation Cost in Delhi for Different Capacity Solar Systems?

What are the Benefits of Installing On-Grid Rooftop Solar Panel Systems for Homes?

Investing in an on-grid rooftop solar system with half-cut solar panels is particularly beneficial for homeowners, as on-grid solar, when sized appropriately, can reduce electricity bills to zero or near zero. Moreover, it can resolve Delhi’s burning problem of air pollution by offsetting thousands of kilograms of carbon dioxide over its 25-year lifespan of delivering clean solar electricity.

Let’s have a closer look at the benefits of installing on-grid solar systems in Delhi:

• They shrink hefty bills by at least 90%: You no longer rely on expensive grid power to run your home appliances. Since all energy requirements are met with solar electricity, electricity bills are reduced by 90% or more. Most homeowners eventually report getting no bills.
• They save tens of lakhs of rupees: The system will work for 25+ years. During that span, you won’t be paying electricity bills as you won’t rely on expensive grid power for your home energy needs. Over 25 years, the savings are in tens of lakhs of rupees.
• They can reverse air pollution in Delhi: Even a 1 kW solar system has the same environmental impact as planting 39 full-grown trees. It can offset ~26,000 kg of carbon emissions over 25 years. Can you imagine how pure the air in Delhi could be if all homes, housing societies, and industries switched to solar?

Conclusion

The 1 kW solar panel price in Delhi with subsidy for on-grid solar systems in 2025 can range between ~Rs. 20,000* and ~Rs. 52,500*. Since it generates only 1,400 to 1,450 electricity units annually, a 1 kW solar system is usually not enough to power an entire household. It can run basic appliances like lights or fans, but can’t power heavy-load appliances, such as washing machines, ACs, refrigerators, or coolers.

FAQs

Q1. Can a 1 kW solar panel run AC?

Ans. No, 1 kW is not considered an ideal system size to power an air conditioner. If you have 1 1.5-ton AC, a 3 kW system is required, and for 2 1.5-ton ACs, you’ll need a 5 kW solar system.

Q2. How much space is needed for a 1 kW solar panel system?

Ans. You will need ~100 square feet of shadow-free area on the roof to install a 1 kW on-grid solar system.

Q3. Can a 1 kW solar panel run a washing machine?

Ans. A 1 kW solar system can technically supply electricity to a washing machine, but it is not considered the right system size for this appliance. A washing machine draws a high starting surge, and the limited generation from a 1 kW setup cannot reliably support that demand. Homes that plan to run a washing machine through solar generally require a larger system for smooth operation.
