Solar PV systems designed for residential & commercial buildings offer a wide range of applications. These systems can be installed on both commercial and non-commercial buildings and apartments, regardless of their type, size, or overall structure.
The primary purpose of installing solar panels is to provide a reliable and sustainable power supply for the building. In addition to electricity generation, solar panels can also be used for solar water heating, ensuring a consistent supply of hot water based on usage requirements.
In some cases, solar systems are used for thermal heating to help regulate indoor temperatures, contributing to improved energy efficiency and maintaining a comfortable environment within the building.

Three Ways Solar-Powered Buildings and Apartments Can Enhance Efficiency
There are 3 ways that solar-powered buildings enhance efficiency:
- Solar-powered buildings improve the competence of heating and cooling systems by up to 30% with proper HVAC system installation. Solar energy-efficient buildings can decrease the operating costs of solar water heaters by up to 90%.
- The use of Low-Emissivity (Low-e) Window Glazing can decrease the need for space cooling by approximately 40%.
- Employing energy-efficient lighting and appliances can decrease energy consumption in a solar building by 20-30%.
Six Reasons for Adopting Solar Energy Technologies in Buildings and Apartments:
- Rising energy consumption.
- Environmental awareness.
- Addressing global climate change.
- Corporate social responsibility (CSR) benefits for corporate buildings.
- Attraction to cleaner, renewable energy.
- Enhanced property value and social appeal.
FAQs on Solar Panels for Apartments & Buildings
Yes, solar panels can be installed in apartment buildings. They are usually mounted on the rooftop or other available common areas. The electricity generated can be used for common facilities such as lifts, corridor lighting, water pumps, parking lights, and security systems.
The solar system is generally owned by the apartment association or housing society. In some cases, a third-party developer installs and maintains the system under a power purchase agreement (PPA).
Solar power is commonly used for common-area consumption. Individual apartments can also benefit if the system is designed with sub-meters or net metering, allowing energy credits to be distributed based on usage or contribution.
On average, 100 square feet of shadow-free rooftop space is required for every 1 kW of solar capacity. The exact requirement depends on panel efficiency and building design.
Yes, net metering is available in many states. It allows excess electricity generated by the solar system to be exported to the grid, reducing the overall electricity bill of the apartment complex.
The cost depends on system size, panel type, inverter, installation complexity, and location. For large apartment buildings, costs are lower per kW due to economies of scale. Government subsidies may also reduce the overall investment.
Yes, the Government of India offers subsidies for residential solar projects, including group housing societies, subject to eligibility and state DISCOM policies.
Savings depend on electricity consumption and system size. Typically, apartment buildings can reduce common-area electricity bills by 30% to 70% using solar power.
Solar panels require minimal maintenance. Periodic cleaning, inverter checks, and electrical inspections are usually sufficient. Most systems come with long-term warranties.
