Factors Affecting the 30 kW Solar Panel System Price in India in 2025

The 30 kW rooftop solar system price in India varies based on multiple factors, including the type of solar system you’re installing (on-grid, off-grid, or hybrid), the type and efficiency of solar panels and solar inverters, and the number of floors in your housing society. 

Let’s check out all the factors that influence the final 30 kW solar panel system price in India in 2025:

• Type of solar system: On-grid solar systems are the cheapest and easiest to maintain. Since off-grid and hybrid solar systems have lithium batteries, they’re more expensive to install and maintain.
• Whether or not you’re eligible for a subsidy: The government offers housing societies a subsidy for installing on-grid rooftop solar systems. If you’re not eligible for this subsidy, your system will cost more. 
• Type of solar panels: Made-in-India DCR modules make you eligible for a subsidy, reducing the cost of a 30 kW solar system. Additionally, higher-efficiency solar panels tend to be more expensive than low-efficiency modules, as they generate more electricity and perform better.
• Type of solar inverter: An MPPT solar inverter is expensive, but it also ensures your solar panels are producing the maximum possible output at all times during any given point in the day.
• DISCOM charges: DISCOMs may charge additional fees based on grid connectivity upgrades, transformer requirements, or safety inspections.
• Mounting structure height: The taller the mounting structure, the higher the cost of materials and labor.
• Type of after-sales service: Opting for a full-service Annual Maintenance Contract (AMC) or extended warranty can increase your upfront cost but reduce long-term maintenance expenses.
• Roof height: Higher rooftops may require more scaffolding, labor, and safety compliance measures during installation, all of which can raise overall costs.
• Number of floors in your society: Societies with multiple floors need longer cable runs and complex routing to reach the meter room. It increases equipment and labor charges, affecting the final installation cost.

What Are the Types of a 30 kW Solar System in India?

The three main types of a 30 kW solar system in India are on-grid, off-grid, and hybrid. An on-grid solar system is connected to the main utility grid. An off-grid solar system is connected to a lithium battery bank, not the utility grid. And, a hybrid solar system is connected to both the grid and a lithium battery bank.

For housing societies with a reliable grid, a 30 kW on-grid solar system is the best option. It has a quick payback period of ~1.5 years, and since it doesn’t require a battery, its installation cost is significantly lower than that of the other two types. 

Let’s check out all types of 30 kW solar systems in detail.

#1. 30 kW On-Grid Solar System and How it Works

A 30 kW on-grid solar system is connected to the main utility grid. When the solar panels in the solar system generate more power than can be consumed in real time, the bi-directional net meter exports it to the grid. At night, the meter imports electricity from the grid to keep loads running. 

Here are the main components of an on-grid solar system and how they work:

• Solar panels generate DC power: Solar panels are composed of solar photovoltaic cells that capture visible light from solar radiation and convert it into direct current (DC).
• Solar panels are secured on top of solar mounting structures: Elevated mounting structures keep solar panels secured. The high-quality WindPro Mount™ IIT-Bombay-approved mounting structures by SolarSquare are perfect for high-rise societies since they can withstand cyclonic winds up to 170 kmph. 
• DC output from solar panels goes to a solar inverter: The solar inverter converts direct current into alternating current (AC).
• Additional units are sent to the grid during daytime: If the solar system produces more power than can be consumed, the bi-directional net meter sends it to the grid.
• Electricity is imported from the grid at night: The net meter imports electricity from the grid to keep the loads running at night.
• The net meter records the unit exchange between the grid and the solar system: This is very important. Ultimately, it determines whether your system supplied more units to the grid or consumed more electricity from the grid. You get a solar bill only if you imported more units than your system exported. 

#2. 30 kW Off-Grid Solar System and How it Works

An off-grid solar system, also known as a standalone solar system, isn’t connected to the utility grid. Instead, it’s connected to a battery bank that stores solar energy.  

Here are the main components of a 30 kW off-grid solar system and how they work:

• Solar panels capture sunlight: These panels, just like the ones in on-grid systems, capture sunlight and convert it to DC electricity. 
• Solar inverter uses its inbuilt MPPT solar charge controller to charge batteries: The charge controller ensures batteries are charged safely.
• Batteries supply electricity at night, or whenever needed: The inverter converts DC from batteries to AC to keep the load running at night.

#3. 30 kW Hybrid Solar System and How it Works

A 30 kW hybrid solar system is the most expensive type as it’s connected to both the grid and a lithium battery bank, making the setup complicated. 

Here are the main components and their role:

• Solar panels generate electricity as usual: They capture sunlight and turn it into DC power.
• Solar inverters convert a portion of DC to AC: During the daytime, the load continues to run on the electricity produced by the panels. The inverter turns DC to AC for this purpose.
• Additional units are sent to the built-in charge controller: The inverter checks the battery status and, if needed, uses additional generated current to charge the batteries safely.
• If anything remains, it is transferred to the grid: The bi-directional net meter sends any excess electricity remaining to the utility grid.
• Energy stored in the batteries is used at night or whenever needed: The inverter converts DC to AC, keeping the load running whenever needed.

On-Grid vs Off-Grid vs Hybrid: Which is Better and Why?

An on-grid solar system is better than off-grid and hybrid solar panel systems because its payback period is ~1.5 years, and it’s the most affordable option. Moreover, there’s no limit to sending additional electricity generated by the solar panels to the utility grid. 

Since net metering allows unlimited unit exchange between the grid and the solar system, housing societies with a reliable grid connection don’t need to invest in batteries, which are not a one-time expense. Lithium batteries are expensive to install, maintain, as well as replace. 

Here’s a tabulated snapshot of how these three types of solar systems truly differ:

*Please note: The above-mentioned 30 kW solar panel system price in India for on-grid systems is indicative as of 27th August 2025 for the SolarSquare’s Blue 4-8ft variant. The final cost of installing on-grid rooftop solar systems in housing societies 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, number of floors in your society, etc. The solar plate prices listed above are for DCR subsidy projects only. Also, SolarSquare does not install off-grid or hybrid solar systems. The prices for off-grid and hybrid PV systems mentioned above are based on standard market estimates.

What Are the Benefits of a 30 kW Solar Panel System?

Installing a 30 kW solar panel system in your housing society can reduce the common area electricity bill since the system will generate ~40,500 to 42,000 units of free solar electricity annually. It will also reduce the carbon footprint of your society, placing you among green societies. 

Let’s check out the multiple benefits of installing an on-grid rooftop 30 kW solar panel system in a housing society: 

• It will reduce your carbon footprint: Installing a 30 kW solar system is equivalent to planting 1,176 full-grown trees that can offset 7,76,160 kg of carbon dioxide from the atmosphere in 25 years.
• It will increase the property’s value: Having a solar system naturally implies that the common area utility bill will be significantly lower. People tend to pay more for energy-independent properties.  
• It will reduce the common area electricity bill: Since the system will generate free solar electricity, the common area utility bill will be reduced. In the end, you’ll save crores of rupees that would otherwise go into paying hefty electricity bills. 

How Many Solar Panels Are Needed for a 30 kW Solar Panel System?

You can use this simple formula to calculate the number of solar panels needed to reach the desired system capacity:

Let’s assume you’re using 540Wp bifacial modules to install a 30 kW solar system in your housing society. You’ll need approximately 56 solar panels to reach the desired capacity. Let’s check out the calculation route:

Ground-Mounted vs Rooftop Solar: Why’s Rooftop Solar Better for Housing Societies?

Rooftop solar systems are easier to install and do not require open land areas for installation. Furthermore, the Indian government offers a subsidy to housing societies installing on-grid rooftop solar systems. On the contrary, this subsidy is not available for ground-mounted solar systems.

It’s better to install rooftop solar systems because ground-mounted solar systems are expensive, require substantial investment to purchase land for the solar system setup, and the government doesn’t provide any subsidy assistance for these solar systems.

Let’s check out how the two truly differ and why rooftop solar systems are better for housing societies:
