4 kW Solar Panel Price in Gujarat With Subsidy in 2025: Subsidy and ROI Calculations Included

The 4 kW solar panel price in Gujarat with subsidy ranges from ~Rs. 1.62 lakh* in Ahmedabad to ~Rs. 1.67 lakh* in Surat for on-grid rooftop solar systems. 2025 is the best time for homeowners and housing societies to install rooftop solar because, as of now, the government is offering a subsidy under the PM Surya Ghar Muft Bijli Yojana. As a result, you can install solar at lower rates. Without a subsidy, the 4 kW solar system cost in Gujarat can range from ~Rs. 2.40 lakh* to ~Rs. 2.45 lakh*.

*Please note: The above-mentioned 4 kW solar system price in Gujarat is indicative as of 15th September 2025 for the SolarSquare Blue 6ft variant. The final 4 kW solar system cost 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.

Investing just ~Rs. 1.62 lakh as the 4 kW solar panel price in Ahmedabad today can offer savings of ~Rs. 16.48 lakh* during the 25-year life of the rooftop solar system. Would you invest ~Rs. 1.62 lakh for installing an on-grid solar system that can save Rs. 16.48 lakh* in 25 years, or spend all the money you could have saved to pay hefty electricity bills that increase by 3-6% annually? 

Think about it! No other form of investment can offer ~10x returns on investment, except for on-grid rooftop solar panel systems for homes.

*Please note: When calculating savings, we have considered an annual tariff escalation of 3% and an annual degradation of 1%. The actual final savings from a 4 kW solar system depends 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.

In this blog, we have explained the 4 kW solar panel price in Gujarat with subsidy, the detailed ROI breakdown, the total subsidy assistance offered by the government, how to avail a solar subsidy in 2025, and the benefits of installing solar systems. We will list down the reasons why on-grid rooftop solar systems for housing societies and homes are better than off-grid solar systems and hybrid solar systems. 

TL;DR Summary Box: What is the Subsidy for a 4 kW Solar Panel System in Gujarat?

The Indian government is offering homeowners a subsidy of Rs. 78,000 under the PM Surya Ghar Muft Bijli Yojana for installing 4 kW solar systems. However, you must ensure that the system is strictly an on-grid rooftop solar system for residential usage to be considered eligible for this subsidy scheme. This assistance is not offered for commercial rooftop systems, ground-mounted solar systems, or off-grid solar systems.

How Many Solar Panels are Needed for a 4 kW System?

The number of solar panels needed for a 4 kW solar system actually depends on the wattage of the solar panel you’re using. 

Let’s give you a sample calculation using the formula:

Suppose, you’re using 540Wp bifacial solar panels. You will need ~8 solar panels to build a 4 kW solar system. 

Here’s the calculation:

What Are the Types of a 4 kW Solar System? Cost Comparison Included

On-grid, off-grid, and hybrid solar systems are the three primary kinds of solar systems used in India. On-grid solar systems are more economical than off-grid and hybrid solar systems as they do not require lithium batteries to store excess solar energy. Before we understand the exact cost difference that makes on-grid the most preferred choice for homes in India, let’s learn how these systems work:

• On-grid solar systems: They are connected to the utility grid. When the solar panels produce excess solar energy, a bi-directional net meter sends extra current to the grid for storage. At night, energy is imported from the grid to keep the house powered. This unit exchange is recorded by a net meter, and the process is called solar net metering. 
• Off-grid solar systems: They are not connected to the grid like on-grid PV systems. Instead, they use a lithium battery bank to store excess solar energy generated by the solar panels. Since lithium batteries are expensive and require replacement, the off-grid systems are way more expensive. Plus, the government does not provide homeowners with a subsidy for installing off-grid solar systems.
• Hybrid solar systems: They are connected to the grid as well as the lithium battery bank. Excess solar energy first charges the battery; if anything remains after that, the net meter sends it to the grid. These are the most expensive of the three types. 

Now let’s check out the cost comparison between the three types of solar systems in Gujarat:

 *Please note: The above-mentioned 4 kW solar panel price in Gujarat with subsidy for on-grid systems is indicative as of 15th September 2025 for the SolarSquare Blue 6ft variant. The final solar plate price 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. Also, the prices for off-grid and hybrid solar systems are based on standard market estimates and may vary from the said range based on the type of batteries, panels, brand, and inverters you choose. SolarSquare does not sell or install off-grid or hybrid solar systems. We only install on-grid rooftop solar systems for homes, housing societies, commercial complexes, and industries.

Is 4 kW Enough to Power a House in Gujarat?

FAQs

Q1. Can you run AC on a 4 kW solar panel system?

Ans. Yes, you can easily run a one 1.5-ton AC on a 4 kW solar system that generates 5,600 to 5,800 units of electricity annually.

Q2. How many units per day can a 4 kW solar system generate?

Ans. Based on the yearly range of 5,600 to 5,800 units, a 4 kW solar system can generate ~467 to ~485 units of electricity per month. However, actual output from a solar system is not consistent across all months. The power generation is lower during the monsoons and higher during the summer season.

Q3. Can solar panels run on cloudy days?

Ans. Yes. Solar panels work on cloudy days because solar systems use light from sunlight, not heat, to produce electricity. While the output is lower than on a bright sunny day, your PV system will still produce electricity under cloud cover.
