India crossed 100 GW of installed solar capacity in 2025, and rooftop solar is the fastest-growing segment within it. The PM Surya Ghar Muft Bijli Yojana, launched in February 2024, brought a central subsidy of up to ₹78,000 for residential systems, and over 1.4 crore households had registered by mid-2025. For a typical Indian home consuming 250–400 units a month, a 3 kW rooftop system now costs ₹1.5–1.8 lakh after subsidy, with payback periods of 4–6 years and a 25-year panel warranty.
Beyond economics, solar makes practical sense in cities like Hyderabad where summer cooling loads spike electricity bills past ₹6,000–₹10,000 a month for a 3 BHK apartment or villa. This guide covers how solar systems work, what equipment goes into a residential setup, what subsidies and net-metering rules apply, and what to look for during installation and maintenance.
The Advantages of Employing Solar Power Systems
- Solar energy is renewable and sustainable, thus it ensures a long-term source of power with no risk of depletion.
- A reduction in carbon footprint for homeowners with solar power systems installed, which in return helps mitigate the adverse effects of climate change.
Available Types of Solar Power Systems
There are two types of power systems for residential use:
- Grid-Tied Systems: These systems are connected to the utility grid and allow homeowners to sell whatever excess electricity is made back to the grid/the power providers through a net metering system. Thus the system helps owners offset their energy consumption while generating income through the selling of surplus energy.
- Off-Grid Systems: These systems run independently from the power grid. They generate and store electricity in solar batteries and encourage the concept of off-grid living, which is a lifestyle that is centred around energy independence and self-sustainability. An off-grid system warrants a higher investment per setup when compared to grid-tied solar systems.
Components Of Solar Power Systems
For the installation of a solar power system, you need solar panels, less popularly known as photovoltaic (PV) panels which are to be installed on the rooftop or other such suitable location from where it can successfully capture sunlight which will be then converted into electricity.
Each solar panel is made up of multiple solar cells that generate direct current, and DC electricity. Solar Inverters are then set up and used to convert DC electricity into AC (Alternating Current) which we all can then use for our everyday use.
Financing Option and Government Incentives
Various incentives have been introduced by the Indian Government to encourage citizens to adopt solar energy. The Solar Investment Tax Credit (ITC) is one such notable incentive which provides a substantial tax credit for homeowners who opt to install solar systems. Additionally, the Telangana State Government and utility companies have offered rebates, subsidies, and highly profitable net metering programs to enhance the allure of solar energy.
Maintenance of Solar Power Systems
Though solar power systems require little to no daily maintenance, they do require regular monitoring for all components to function optimally and for them to generate the most possible electricity. You can utilize the help of mobile apps and online portals provided by the panel provider or a third party to monitor the performance track energy production, and detect issues.
By ensuring periodical cleaning of the solar panels, and by removing dust and debris to maximum sunlight absorption you will elongate your system’s life and benefit from regularly high energy outputs.
Solar power systems give a sustainable, cost-effective solution to Indian homeowners by allowing them to easily tap into a clean, renewable source of energy. The luxury villas in Hyderabad already come equipped with the setup required for solar panel installation. As a result, its allure amongst the more carbon-emission-conscious population has sky-rocketed in recent times.

How do solar power systems work in Indian homes?
Rooftop solar panels convert sunlight into electricity through photovoltaic cells. The generated power can be used directly, stored in batteries, or fed back to the grid for credits under net metering, significantly reducing electricity bills.
What is the cost of installing solar panels for a home in India?
A 3 kW rooftop solar system suitable for a typical Indian home costs Rs 1.5-2.5 lakh after government subsidies. The system typically pays for itself within 4-5 years through electricity bill savings and has a 25-year lifespan.
What government subsidies are available for residential solar installations?
The PM Surya Ghar scheme offers subsidies of Rs 30,000 per kW for systems up to 2 kW and Rs 18,000 per kW for 2-3 kW systems. Homeowners can apply through the national portal and receive the subsidy directly in their bank accounts.
