Types of 7 kW Solar Systems and Their Prices in India in 2025

The three main types of solar photovoltaic systems in India are on-grid solar systems, off-grid solar systems, and hybrid solar systems. Out of the three types, on-grid solar systems are most recommended for residential and commercial rooftop systems as they’re the most cost-effective option. Since they do not require expensive lithium batteries, unlike off-grid and hybrid systems, they’re cheaper to install and maintain.

Here’s a table comparing the 7 kW solar system installation cost for different types of solar systems: 

*Please note: The above-mentioned 7 kW solar system price in India with subsidy is indicative as of 7th October 2025 for the SolarSquare Blue 6ft variant. The final 7 kW 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. Additionally, SolarSquare does not sell or install off-grid or hybrid solar systems. We exclusively install on-grid rooftop solar systems for housing societies, homes, commercial buildings, and industrial facilities. 

Now, let’s check out how the three solar system types work and differ from each other:

• On-grid solar system: The excess solar energy generated by the solar panels during the daytime is sent to the grid. At night or whenever needed, electricity can be imported from this grid. This entire process is known as solar net metering, and it eliminates the need for a lithium battery bank to store solar energy. 
• Off-grid solar system: The excess solar energy is stored in a lithium battery bank, as off-grid PV systems are not connected to the grid. The energy stored in the battery is used at night or whenever needed to run the load. Since lithium batteries are expensive, off-grid solar systems are a lot more expensive than on-grid solar systems.
• Hybrid solar system: This is the most expensive type of PV system. It’s connected to a lithium battery bank as well as the grid (if the discom allows). The excess solar energy is first used to charge the lithium batteries through an MPPT solar charge controller. Then, if the DISCOM permits net metering and there’s excess current left, it’s sent to the grid. 

Here’s a table that cites the differences between the three types of solar systems and explains why on-grid solar is the best option for both residential and commercial customers:

We exclusively install on-grid rooftop solar systems for homes, housing societies, commercial buildings, and industrial facilities. 

How Much Money Can a 7 kW On-Grid Rooftop Solar System Save in 25 Years of its Lifetime?

Being the cheapest of the three solar system types isn’t the only reason you should install an on-grid rooftop solar system. Another reason to install an on-grid solar system is the 5-10x returns it offers. For instance, investing just ~Rs. 3.52 lakh* as the 7 kW solar system price in Pune can offer savings of ~Rs. 46.85 lakh* over 25 years. That’s almost 13 times the return on initial investment.

For demonstration purposes, let’s assume you’re using high-efficiency solar panels, such as the 545Wp bifacial solar panels with mono-PERC half-cut solar cells, to build a 7 kW solar system. Here’s the sample calculation for this use case:

Is 7 kW Enough to Run a House?

A 7 kW system is more than enough to power a 4 BHK house with multiple heavy appliances, as it can generate 9,800 to 10,150 units of electricity annually. 

Please note: On average, a 1 kW solar system in India can generate 1,400 to 1,450 units of electricity. 

Here are the common appliances that a 7 kW solar system can easily power in a home: 

• 2-3 air conditioners (1.5 tons each)
• 1 Refrigerator
• 1 Washing machine
• 1 LED Television
• 5-6 ceiling fans
• 5-6 LED bulbs
• Kitchen appliances, including a microwave, mixer, and induction cooktop
• Laptops and charging devices

Here’s a tabulated snapshot of the number of electricity units a 7 kW solar system can produce during its first year in different cities:

*Please note: The generation figures mentioned above are approximate and meant for general reference only. Actual output can vary from these estimates due to multiple factors, such as pollution levels in your city, changes in sunlight availability, weather patterns, roof angle, panel direction, shading from surrounding objects, and dust accumulation. Technical elements, such as solar panel efficiency, inverter performance, wiring quality, and system losses, can also impact generation levels. Even routine maintenance and regional temperature fluctuations can affect the amount of power your system produces over time.

What Are the Benefits of Installing an On-Grid Rooftop Solar System?

Installing an on-grid rooftop solar system is beneficial as the system’s payback period is just 3-5 years with a subsidy. Additionally, it generates free solar electricity for 25+ years, offers 5-10x returns on investment, offsets carbon dioxide, is eligible for a government subsidy, and reduces electricity bills by 90% or more.

Let’s check out all the benefits that make on-grid solar systems the best for residential solar installations:

• They’re eligible for a subsidy: Homeowners can install on-grid rooftop solar systems at lower rates by applying for a subsidy under the PM Surya Ghar Muft Bijli Yojana. 
• They offset carbon dioxide: A 7 kW solar system is equivalent to planting 274 trees, which can offset 1,81,104 kg of carbon dioxide from the atmosphere in 25 years.
• They have a quick payback period: It takes just 3 to 5 years to recover the installation cost with a subsidy. Moreover, the returns can be 5-10x or higher. No other form of investment can offer such high returns.
• They reduce electricity bills by 90% or more: They continue to generate electricity from sunlight for over 25 years. As a result, your reliance on expensive grid electricity is reduced by 90% or more. Many customers receive zero bills after installing a solar system. 
• They save tens of lakhs of rupees over 25 years: Since you no longer pay for electricity bills, which increase by 3-6% annually, all that money is now saved. And the savings are massive!

Why Choose SolarSquare’s 7.02 kW Solar System?

Most solar companies sell you a standard 7 kW system and call it a day. But there’s a catch that nobody explains! When you break down the math based on solar panel wattage, 7 kW doesn’t add up cleanly.

Here’s what we mean:

A 7 kW system equals 7,000 watts. Divide that by 545, and you get 12.84 panels. No one can mount 12.84 panels on your roof. It’s either 12 or 13. What does this mean? You are either getting shortchanged on power output or the design is compromised to fit what’s available.

At SolarSquare, we don’t believe in such compromises! Instead of forcing a mismatch, we offer a 7.02 kW system with 13 full panels. We use high-performance 545-watt bifacial solar panels that generate maximum output and offer the best returns on your investment.
