Slash Your Society's Electricity Bills by up to 90%!

Installing rooftop solar for housing societies is highly beneficial, as it can substantially reduce the common area electricity bill and lower the society’s carbon footprint manifold. A housing society that runs on green solar energy is likely to attract eco-friendly citizens, and will have lesser Common Area Electricity charges which, in turn, increases the property prices. Overall, the monetary and environmental benefits of residential solar power usage in housing societies make the investment worthwhile.

The cost of residential solar power panels for housing societies ranges from ~Rs. 60,000* per kW to ~Rs. 65,000* per kW – though this may vary project to project depending on several factors.. However, thanks to the subsidy offered under the PM Surya Ghar Muft Bijli Yojana, housing societies can install solar panels for flats at much lower rates. With the applicable government subsidy of Rs. 18,000 per kW for systems up to 500 kW, the cost of residential solar power systems for housing societies ranges between ~Rs. 42,000* per kW to ~Rs. 47,000* per kW.

*Please note that prices are subject to change: The above-mentioned cost of a solar panel for apartments for on-grid solar systems is indicative as of 26th April 2026. The final cost of solar panels for a housing society depends on your DISCOM charges, city, solar system size, site conditions, project specifications, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc.

In order to fully reap the financial benefits of installing housing solar systems, you must choose the best solar installation company. A well-installed rooftop solar system can last 25+ years with proper maintenance. That makes it worth asking a simple question: Will your installer still be around throughout the system’s entire lifetime?

One of the most reliable ways to assess this is by reviewing the company’s track record. An installer with decades of experience in rooftop housing solar projects is far more likely to remain operational and capable of supporting your system in the years ahead.

For instance, SolarSquare, the #1 home solar company in India (in terms of number of installations carried out, as listed on the PM Surya Ghar Muft Bijli Yojana National Portal), has installed a total of 20 MW of solar capacity across 500+ housing societies. Our residential solar power systems have maintained a storm-safety record of 99.91% over the last two years, and we’re the only solar company in India that offers a generation guarantee with a money-back promise.

Read on to explore the cost of installing rooftop solar in housing societies both with and without the PM Suyra Ghar subsidy, services that make SolarSquare the best residential solar company in India, the benefits of using solar power for apartments, and the types of residential solar systems.

What’s the Cost of Rooftop Solar for Housing Societies?

The cost of residential solar power panels varies by city and depends on factors such as system size, site conditions, and housing solar project specifications. On average, the cost of a solar panel for a society can range between ~Rs. 60,000* per kW to ~Rs. 65,000* without any financial assistance from the government.

Before we explain the total subsidy you can claim under the PM Surya Ghar Muft Bijli Yojana for installing solar in housing societies, let’s have a look at the estimated cost of installing rooftop solar for housing societies for different-capacity solar systems without any subsidy assistance.

Is there any Solar Subsidy for installing Solar Panels for Flats?

The central government offers financial assistance of Rs. 18,000 per kW to housing societies installing grid-connected solar systems for residential usage under the PM Surya Ghar Muft Bijli Yojana. The maximum subsidy for solar panels on flats under this scheme is capped at Rs. 90 lakh for systems of 500 kW or more.

Here’s a tabulated snapshot of the total solar subsidy you can claim for installing solar panels for apartments in India:

What’s the Cost of Residential Solar Power Systems for Housing Societies with a Subsidy?

The cost of rooftop solar for housing societies reduces significantly with a subsidy. The final estimated price of residential solar systems for housing societies with subsidy is between ~Rs. 42,000* per kW and ~Rs. 47,000* per kW.

Here’s a snapshot of the cost of solar panels for flats with subsidy:

How Much ROI Can You Expect From Solar Panels for Apartments in India in 2026?

Installing solar panels for residential buildings in India can save lakhs, and even crores, of rupees by bringing common-area electricity bills down to zero or near zero.

Here is a snapshot of housing societies and establishments where we installed rooftop solar systems, along with the savings they have generated to date.

Case Studies that Demonstrate the Real Impact of Installing Solar in Housing Societies

Numbers in a table only go so far. Payback can look very different in the real world. So, we made case studies in October 2025 for two societies we worked with, one in Pune and one in Mumbai, to explain the real impact of going solar for housing societies.

• Godrej Infinity, Keshav Nagar, Pune (400 kW system, commissioned June 2024): This was a large society with a high common-area load. We installed a 400 kW rooftop system that qualified for a PM Surya Ghar Yojana subsidy of Rs. 72,00,000, reducing the upfront cost. As of October 2025, when this case study was done, the plant had already generated more than 8.1 Lakh units. The environmental side is just as concrete. The plant has offset 665 tonnes of CO2, equivalent to saving 30,000 trees.
• Ashford Royale A Wing, Bhandup, Mumbai (75 kW system, commissioned June 2024): This was a smaller society and a smaller solar system. The 75 kW installation received a subsidy of Rs. 13,50,000 under the PM Surya Ghar Yojana. The system has generated 1.4L units as of Oct 2025. Breakeven came in at 1.6 years. CO2 offset stands at 114 tonnes and 5,200 trees saved. This case study matters because it shows the math holds at a smaller scale, too. You do not need a 400 kW system to make solar work for your society. The savings for this society as of April 2026 stand at Rs. 26,41,000.

What are the Different Financing Options for Solar Housing Solutions for Societies?

There are three main ways to finance solar panels for flats in India in housing societies, including CAPEX financing, OPEX financing, and SolarSquare’s ZIP loan.

The right option depends on how much capital the society wants to invest upfront and how quickly it wants to start saving. SolarSquare, the #1 solar installation company, caters to all these financing options:

• CAPEX (Corpus Funding): The society invests from its own corpus and owns the housing solar system outright from day one. All electricity generated reduces the common area bill directly, which means 100% of the savings flow back to society. This option delivers the highest long-term ROI and the fastest path to zero or near-zero common-area electricity bills. However, it requires the largest upfront commitment to install solar panels on flats.
• SolarSquare’s ZIP (Zero Investment Plan): This is SolarSquare’s zero-investment solar loan that lets a society install a solar panel for flats in India with no out-of-pocket upfront payment. The government subsidy offsets the upfront payment, and EMIs can be spread over 6-60 months. The society owns the housing solar system, builds equity from day one, and turns net positive on cash flow almost immediately.
• OPEX (Third-Party Investment): A third party funds, installs, and maintains the solar system on the society’s rooftop. The society pays only for the units of solar electricity it consumes, usually at a tariff lower than the grid rate. There is no capital outlay or maintenance burden, but the savings are smaller than with CAPEX or ZIP because the society does not own the asset.

Why Choose SolarSquare to install Solar Panels for a Housing Society?

SolarSquare is the #1 residential solar company in India, with 20 MW of installed capacity across 500+ housing societies. We’ve helped our customers receive more than Rs. 250 crore in government solar subsidies, including ~Rs. 20 crore specifically for housing societies.

Let’s take a look at the multiple services we offer that have made us the best residential solar company in India.

#1. We’re the Rooftop Solar Partner for India’s Largest Housing Societies

When a society needs to power hundreds of homes from one rooftop, the margin for error drops to zero. Sizing has to be right, structural load calculations have to be right, the subsidy paperwork has to be right, and the system has to deliver from day one. This is the work we have built our reputation on.

Raheja Vistas CHS in Mumbai is India’s largest subsidized housing society solar project under the PM Surya Ghar Yojana, and SolarSquare executed it. That’s an 810 kW system, and no other residential society in the country has gone bigger on this scheme.

That project sits at one end of our range. At the other end, we install smaller capacity PV systems for individual homes. So, regardless of your society’s scale, we have the engineering depth, vendor relationships, and subsidy expertise required for proper installation.

Here are five of the largest housing solar projects we have executed in India:

#2. Cyclone-proof Solar Mounting Structures

Solar panels are only as strong as the mounting structure that holds them down. That’s why SolarSquare uses WindPro Mount™, an IIT-Bombay-approved mounting structure built to handle the toughest weather conditions. It’s designed to remain intact even at wind speeds of 170 km/hr.

Here’s what sets WindPro Mount™ apart:

• Manufactured using virgin steel for consistent strength and long-term reliability.
• Built to withstand cyclonic winds of up to 170 km/hr.
• Protected with an 80-micron hot-dip galvanized iron (HDGI) coating, adding an extra layer of durability against rust and wear for 25+ years.

#3. Generation Guarantee with a Money-back Promise

Most solar companies only talk about savings. SolarSquare puts a number behind it and takes responsibility for delivering it.

We are India’s first and only solar company to back solar performance with a generation guarantee and a money-back commitment. If your solar system fails to produce the energy units expected, we pay you for the shortfall at Rs. 8 per unit.

#4. 5-Year After-Sales Servicing and Maintenance Plan

To keep your system operating at its best, SolarSquare offers 5 years of maintenance services with monthly visits. This goes far beyond routine panel cleaning and focuses on safety and long-term system health.

Here’s what makes our after-sales maintenance plan so special:

• 24/7 remote monitoring: Continuous performance tracking to identify faults, output drops, or system anomalies early.
• Breakdown service and on-call support: Quick-response assistance whenever repairs or immediate attention are required.
• Deep solar panel cleaning: Specialized cleaning tools and solutions that help maintain solar panel efficiency across seasons.
• Comprehensive system inspections: Regular electrical checks for safe power flow, structural evaluations to keep panels and mounts secure in all weather conditions, and mechanical assessments to prevent wear and ensure long-term reliability.

#5. A 99.91% Storm-Safety Record

When severe cyclones hit, poorly installed residential solar systems can turn into safety risks. While several local installations suffer damage or panel displacement each year, SolarSquare’s solar systems have remained firm.

Over the past two years, the company has maintained a 99.91% storm-safety record. This exceptional resilience, even in the face of severe cyclones, stems from the use of WindPro Mount™ structures aligned with BIS engineering standards.

#6. Water-Leakage Warranty

To reduce the risk of water seepage after installation, SolarSquare uses HILTI Airtight chemical anchoring, a method that seals drilled holes rather than leaving them exposed to moisture. This approach significantly lowers the chances of leakage around mounting points.

In the rare event of water seepage, the installation is covered by a Rs. 1 lakh water-leakage warranty for 1 year.

Types of Residential Solar Systems for Housing Societies

The three main types of residential solar power systems for housing societies in India are on-grid, off-grid, and hybrid.

• On-grid solar systems are connected to the grid.
• Off-grid solar systems are connected to lead-acid or lithium batteries instead of the grid.
• Hybrid solar systems are connected to both the grid and a battery bank.

Here’s a summary table that gives you a breakdown of the key features of all three systems, helping you choose the right one based on your needs:

Now, let’s have a look at each type in detail.

On-Grid Residential Solar Power Systems

An on-grid solar system is connected to the utility grid. It does not use lead-acid or lithium batteries to store solar energy because the DISCOM imposes no limit on the number of electricity units that can be exchanged between the grid and the solar system.

As a result, the cost of an on-grid solar panel for a housing society is the lowest, making it the most preferred option in areas with very reliable grid power and rare power outages.

Here’s a step-by-step walkthrough of how these solar panels for flats in India work:

• Solar panels receive sunlight: Photons from sunlight strike the solar cells in solar panels. The absorbed photons transfer their energy to electrons in the solar cells, causing them to move. This flow/movement of electrons in a single direction is direct current (DC) power.
• DC power is converted to alternating current (AC) power: The DC power from solar panels is sent to a solar inverter, which converts it to AC.
• Solar net metering for billing: The DISCOM installs a bidirectional net meter or smart meter at your society after the solar system is installed. This smart meter tracks the energy exchange between the grid and your solar system. If the solar system sends more energy to the grid than it imports, your society receives credits. If your solar system imports more grid power than it exports, you pay the DISCOM at standard electricity rates in your city.

Off-Grid Residential Solar Power Systems

An off-grid solar system, also known as a standalone PV system, is connected to solar batteries instead of a grid. Although batteries increase the cost of off-grid solar systems, they are necessary in areas where the grid is unreliable or unavailable.

Here’s the step-by-step walkthrough of how these solar panels for residential buildings work:

• Solar panels convert sunlight into DC solar electricity: This step works just like it does for on-grid solar systems.
• DC power is used in two ways: Solar energy from panels is converted to AC power to keep the connected load running. A portion of DC that remains unused is used to charge the battery bank.
• Power from batteries offers backup at night or whenever needed: The stored power in batteries is converted to AC by the solar inverter and used at night or whenever needed.

Hybrid Residential Solar Power Systems

A hybrid solar system combines the features of both on-grid and off-grid systems. It is connected to the utility grid while also using lead-acid or lithium batteries to store excess solar energy. This allows housing societies to use solar power during the day, store energy for backup, and still exchange electricity with the grid when required.

Because hybrid systems include batteries and more advanced inverters, their upfront costs are higher than those of on-grid and off-grid solar systems. However, they are well-suited for areas with frequent power outages but still with grid access, as they offer both energy savings and backup reliability.

Here’s a step-by-step walkthrough of how these solar panels for residential buildings work:

• Solar panels generate DC solar electricity: Sunlight hits the solar panels, exciting electrons within the solar cells and producing direct current (DC) electricity.
• DC power is intelligently distributed: The hybrid solar inverter converts DC to AC to power connected loads, such as lifts and other common areas. Excess energy is directed either to charge the batteries or exported to the grid, depending on system settings.
• Battery storage provides backup power: Stored energy in the batteries supplies electricity during power cuts, at night, or when solar generation is low.
• Grid interaction balances energy needs: When solar and battery power are insufficient, electricity can be drawn from the grid. When excess solar energy is available, it can be sent back to the grid, enabling net metering where applicable.

What are the Benefits of Solar Power for Apartments?

Using solar power for apartments in a housing society can result in a massive reduction in common-area electricity bills, increase the value of flats in the society, and offer true energy independence.

Let’s have a closer look at the benefits of relying on solar power for apartments in housing societies:

• Massive reduction in electricity bills: Solar power significantly reduces common-area electricity expenses for lifts, lighting, water pumps, and security systems. This, in turn, can reduce the maintenance fees homeowners pay in housing societies.
• A high government subsidy lowers upfront costs: Under the PM Surya Ghar Muft Bijli Yojana, housing societies receive a subsidy of Rs. 18,000 per kW up to 500 kW.
• Long-term free electricity for common areas: Once the system pays for itself, the society continues to generate electricity for decades, shielding residents from rising power tariffs.
• Contribution to sustainability and net-zero goals: By switching to solar, housing societies reduce their carbon emissions and contribute to India’s national net-zero targets.
• Better financial planning for societies: Lower, predictable electricity costs improve budgeting for RWAs and managing committees, freeing funds for maintenance, upgrades, and resident amenities.
• Increased property value: A solar-powered society is seen as future-ready, environmentally responsible, and cost-efficient, which improves long-term property value and buyer appeal.

Conclusion

Installing rooftop solar for housing societies offers numerous financial and environmental benefits. Since the central government’s PM Surya Ghar subsidy scheme applies to housing societies installing grid-tied solar systems, now is the best time to go solar, as it can be done at cheaper rates.
