The rising cost of electricity can be a serious financial problem. That’s where solar power comes in to save the day and a lot of utility money. A 4 kW solar system is sufficient for a 2 or 3-BHK home. But what is the price of a 4kw solar system? To help you choose the best fit for your needs and budget, here’s the 4kw solar panel price in India with and without subsidy.
Who Should Choose A 4 kW Solar System?
Not all homes require the same size solar system. A 4 kW solar system for home is the perfect size for houses with moderate to high electricity requirements. Here’s a quick checklist to help you determine if this system is right for you:
A 4 kW solar panel is ideal for you if:
- Consume on average 400 – 600 units (kWh) of electricity a month
- Stay in 2BHK or 3BHK or a big independent house
- Use everyday appliances such as a refrigerator, washing machine, 2-3 ceiling fans, LED lights, a TV and a 1-1.5 HP water pump
- Want to regularly power 1 air conditioner during the day
- Have 350-450 sq. ft. of shadow-free roof space
- You are a small business or home office user who needs 24 hour daytime power
Check your electricity bills to calculate the average units you consume. If it falls between the 400-600 unit range, a 4 kW solar system is perfect for you. If you have a bigger house, you can explore the 5 kW solar system price as well. And if you have a small house, you can choose a 2 kW solar system.
What Is The 4kW Solar Panel Price In India Without Subsidy?
Solar panels contribute almost 50-60% of the cost of a 4kW Solar System for home. Therefore, it is vital to calculate the cost of solar panels along with other components.
There are mainly two major technologies used for solar panels, Mono PERC and TOPCon. Both types of solar panels are very popular in India for their durability and efficiency. The price of DCR Mono PERC solar panel is in the range of ₹22 to ₹24 per watt and the price of DCR TOPCon solar panel starts from ₹24 per watt.
A solar system also includes the price for the solar inverter, mounting structure, wiring expense, labour charges, and net-metering expense. You must consider these charges as well to get a better price estimate for your 4 kW solar system.
There are three types of solar systems in India: on-grid, off-grid, and hybrid. Among these three, off-grid solar systems are independent without any connection to the utility grid. The following are the 4 kW Solar System prices for each of the three:
- The 4 kW on-grid solar system price in India is ₹2,60,000 to ₹2,80,000
- The price of a 4 kW off-grid solar system in India is ₹3,10,000 to ₹3,40,000
- The price of a 4 kW hybrid solar system in India is ₹5,90,000 to ₹6,50,000
Note: All these prices can change based on your location, supplier, or if you choose N-DCR solar panels.
What Is The 4kW Solar Price In India With Subsidy?
The 4kw solar panel price can be high for many households. That’s why the government of India offers financial assistance through PM Surya Ghar: Muft Bijli Yojana.
Solar subsidy offered under PM Surya Ghar: Muft Bijli Yojana:
- The 1 kW solar subsidy amount is ₹30,000 per kW
- The 2 kW solar subsidy amount is ₹60,000
- The 3 kW solar subsidy amount is an additional ₹18,000 over the 2 kW subsidy
Under the national solar subsidy scheme, all solar systems above 3 kW were eligible for a fixed subsidy of ₹78,000. You can also use specific subsidies from the state if applicable. Many states like Haryana, UP, Delhi etc. are providing state level subsidies to reduce the cost of solar installation further.
The following table shows the estimated 4 kW solar system price in India with subsidy.
| System Type | Without Subsidy | Subsidy | After National Subsidy |
|---|---|---|---|
| On-grid System | ₹2,60,000 – ₹2,80,000 | ₹78,000 | ₹1,82,000 – ₹2,02,000 |
| Off-grid System | ₹3,10,000 – ₹3,40,000 | Not Applicable | ₹2,32,000 – ₹2,62,000 |
| Hybrid System | ₹5,90,000 – ₹6,50,000 | ₹78,000 | ₹5,12,000 – ₹5,72,000 |

FAQs
Can I run 2 AC on a 4kW solar system?
A standard 1.5-ton inverter AC consumes around 1.2–1.5 kW per hour. Two units together would draw close to 2.4–3 kW, leaving very little headroom for other household appliances like a refrigerator, fans, and lights. You may be able to run one AC comfortably alongside other typical loads, but for two ACs, a 5 kW or 6 kW solar system would give you more reliable and efficient performance.
How much power will a 4kW solar system produce?
A 4 kW solar panel system produces about 16-20 units (kWh) of electricity per day in good sunlight. That works out to about 480 to 600 units a month and 5,500 to 6,000 units a year. The actual output depends on where you live. It depends on the tilt and orientation of the panels, shading on the roof, and the seasonal variation in sunlight.
How many batteries do I need for a 4kW solar system?
The number of batteries you’ll need will depend on the kind of system you go for and also how much backup energy you want. In many cases for an off-grid or hybrid 4 kW solar system, it’s pretty normal to plan on 4 to 8 batteries, each one around 150Ah capacity (12V each), either strung in series or joined in parallel so the setup fits the inverter needs.
Is 4kW enough to power a house?
Yes, a 4 kW solar system can power a medium-sized home in India. It can easily run LED lights, ceiling fan, refrigerator, washing machine, TV, laptop, 1 to 1.5 HP water pump and 1 air conditioner in day time. This system will be suitable for the load profile of a household consuming 400 to 600 units per month.
