With growing awareness about sustainable living, installing solar panels on a building’s rooftop is an excellent idea. Solar panels are a source of clean, renewable energy, applicable across commercial, residential and industrial sectors. Solar panels increase a property’s value and lower carbon emissions and energy costs. Residential properties with solar panels provide long-term benefits and savings despite the initial investment.
In this article, we share the key aspects to consider when buying a house with solar panels.
What are solar panels?
A solar panel is a device comprising an assembly of photovoltaic cells (solar cells) that convert sunlight into electrical energy. The system includes cells made of semiconductor materials, such as silicon, an inverter, AC/DC switches and electrical conduit. Electric current is generated when sun rays fall on the cells.
The direct current (DC) is converted into alternating current (AC) through an inverter that can be used to run electrical appliances and devices.
Are solar panels enough to run a house?
Solar panels for homes can be installed to supply adequate power to an entire house. Based on the energy consumption of a house, a fixed number of solar panels can be installed. This will depend on various factors, such as the home solar panel system, energy requirements, roof conditions, sunlight availability and climate. Install a fixed number of rooftop solar panels based on the energy consumption to reduce the dependence on grid-supply electricity.
Should you buy a house with rooftop solar panels?
There are various factors to consider before investing in a property with solar panels. These include finances, personal requirements and long-term impact. Here are some points to note:
Cost savings
One can save on electricity bills in the long run by installing solar panels. In India, states, such as Delhi, offer incentives for installing solar panels on rooftops. Depending on the energy consumption and solar panel efficiency, one can benefit from long-term cost savings by investing in a property with solar panels.
Sustainable feature
Rooftop solar panels produce renewable energy by harnessing sunlight. This helps reduce carbon emissions and dependence on other energy sources. Since sunlight is available everywhere, the solar panel is a practical solution to generate electricity sustainably.
Location and sunlight availability
Solar panels require a steady supply of solar energy to work efficiently. It is essential to consider the amount of sunlight the property receives throughout the year. Areas that receive abundant sunlight are more suited for solar power generation. This makes the investment worthwhile and brings higher returns.
Property value
Solar panels add value to a home and increase its resale value. Properties with solar panels sell faster and attract better prices. Thus, investing in a property with solar panels can be a suitable option if one plans to sell the house in the future.
Property maintenance
Solar panels require minimal maintenance. However, like other facilities, solar panels require cleaning or servicing to ensure optimum performance. It is necessary to take the maintenance and upkeep of solar panels and their life span into account before investing in the property.
Financing
Before buying a property with solar panels, it is beneficial to explore financing options, such as traditional loans. Look at the upfront expenses, ownership benefits and long-term benefits to make an informed decision.
Individual needs
If you are considering investing in a property with solar panels, it is essential to assess your individual preferences, such as energy consumption and lifestyle. If the investment aligns with your priorities and sustainability goals, it is a smart decision as it will lead to financial benefits.
Purchasing a property with solar panels may mean a significant investment. However, solar panels are an environment-friendly feature and the house purchase will signify a step towards a sustainable future and cost savings in the long run.
Pros and cons of installing solar panels

| Solar panels require minimal maintenance, including regular cleaning and inspections for proper functioning. | Their maintenance involves certain expenses. Moreover, repairing rooftops in a house with solar panels is more complex. |
| Solar panels increase the property’s resale value. |
Cost of installing solar panels
The investment in solar panels will depend on several factors, such as the size of the solar panel system, its quality, complexity of the installation process, location and incentives. In India, the average cost of a residential solar system can vary from Rs 65,000-2.7 lakh for a 1-5kW system.
Moreover, the solar panel price and installation cost vary based on location and factors, such as local labour rates, permitting charges and regulations. Incentives and rebates provided by some states can help lower the installation cost.
Do installed solar panels enhance the value of your home?
Installation of rooftop solar panels increases a property’s value and enhances the chances of an attractive deal during a property sale. It helps save energy consumption and costs in the long run.
Moreover, many property seekers are becoming environmentally conscious and prefer sustainable living. Thus, solar panels can pave the way to reduce carbon footprint and promote sustainability. It will minimise the dependence on fossil fuels.
Rooftop solar panels represent a tangible investment in renewable energy and energy efficiency. Buyers may perceive homes with solar panels as more valuable due to the added benefits of clean energy production.
How to choose solar panels for homes in India?
- Consider the available space: Make sure there is adequate space for the installation of solar panels. It is also important to consider the design of the solar panels. A standard 250 to 300 Watt peak solar panels is ideal for large-scale installations. You can choose 74 to 100 Watt peak solar panels for medium to large-scale installations.
- Assess your electricity consumption: The choice of solar panels will also depend on the amount of electricity consumed. Consider the outlets you want to power – from all the fans or all lights in the house or area-wise, such as an entire bathroom, the bedroom or the kitchen. The average power provided by a solar cell is 0.5 volts. An entire solar panel is made up of 36 to 72 solar cells. Based on the total electricity consumption per day, choose the right panel and number of panels to suit your needs.
- Consider installation costs: Solar panel installation costs vary from around Rs 40,000 to Rs 6 lakh. Make sure to consider this factor before going ahead with a solar panel.
- Service and maintenance: Besides the initial cost of installation, you may have to take into account the service and maintenance expenses. Choosing a reliable manufacturer or supplier would be an ideal option to reduce unnecessary maintenance costs. Moreover, choose a solar panel under a warranty period.
What kind of inverter does rooftop system use?
There are variouss types of inverters that may be installed on rooftop solar panel system:
- String inverter: This type of inverter takes direct current (DC) power output from all the solar panels and converts it into alternating current (AC) in one central location.
- Microinverters: These are smaller inverters placed on every panel.
- Power optimisers: Power optimisers are installed at the back of each solar panel. They help maximise energy output and turn individual panels into smart modules by tracking their peak output and regulating their voltage before sending the power along to the central inverter.
