India's Solar Rooftop

Numerous people in India have adopted reliable renewable power sources like rooftop solar for homes and workspaces. The photovoltaic cells and solar power units atop commercial and residential buildings have become a common sight in many cities and towns nationwide.

India is among the nations with the highest sustainable or renewable power generation rates. As of 2019, renewable energy sources accounted for 35 percent of the nation's installed power generation capacity, generating 17 percent of the nation's total electricity.

The adoption of rooftop solar panels usage is clearly on the rise. The rooftop solar panel sub-sector has grown faster than every other renewable energy sub-sector, with a compound annual growth rate (CAGR) of 116 percent between 2012 and 2018. Further, The World Bank has pledged US$625 million in financial support for grid-connected rooftop solar projects to help India meet its ambitious objective of attaining 227 GW (it was previously 175 GW) of power generation.

Most importantly, solar power's adoption rate is wider than that of commercial or industrial buildings. With the fast technological advances and the growing distribution network, solar-powered houses are becoming the most natural choice for homeowners in every city and town.

How much of the rooftop should be used for generating electricity?

The maximum power generation capacity is calculated based on the intensity and hours of sunshine and space on the rooftop. Depending on the type of solar power system – on-grid, off-grid, or hybrid – a homeowner can choose the total electricity generation capacity.

Advantages of Solar Power

Apart from being a sustainable, renewable, clean energy source, solar power has several other advantages for industrial and non-industrial consumers.

  • Low running cost

The cost reduction is the most significant advantage of installing rooftop solar panels. Rooftop solar tariffs are 17% to 27% less expensive than industrial and commercial solar tariffs. This is an excellent benefit for both industrial users as well as individuals. Accounting for total lifespan, low running costs, and low installation costs, rooftop solar energy offers a distinct edge over conventional power generation.

  • Reduced greenhouse gas emissions

Rooftop solar power units do not emit carbon dioxide or other poisonous gases. Solar energy is harvested by capturing sunlight through photovoltaic cells, so there aren't any health hazards associated with the system. Solar energy is clean, green, and healthy.

  • Low maintenance cost

Rooftop solar power units are highly cost-effective. There are no significant regular expenditures involved. With regular cleaning and maintenance from time to time, solar power units are easy to install and keep running. Rooftop units typically have a 25-year life expectancy, making their installation an excellent investment. Adani's asset management technology monitors the health and maintenance of installed solar panels so a consumer can be at ease at all times.

  • Perfect for India

India is in the perfect geographical location for solar energy. Most parts of the country obtain plenty of tropical sunlight. With over 300 bright days and clear skies each year, the country's conditions for harvesting solar energy are the most ideal globally.

  • Easy installation

Because the system is installed on the roofs of commercial and residential buildings, it only requires a small amount of land or space. This makes solar energy both viable and sustainable. The added benefit of solar rooftop systems is the higher resale value that one can expect from solar cells.

Q1. What is a rooftop solar PV system with grid connectivity?

In a grid-connected rooftop or small solar photovoltaic (SPV) system, the DC electricity generated by solar panels is converted to AC power by a power conditioning unit or an inverter and then transmitted to the grid.

Q2. How much space is required for a 1 kWp rooftop solar PV system?

In general, a 1 kW rooftop system requires 10 square meters of shadow-free space. However, depending on the effectiveness of the solar modules, their positioning, and other factors, the actual area required may vary.

Q3. What kinds of roofs are appropriate for a rooftop solar (RTS) system?

Rooftop solar PV systems can be built on any sort of roof that can support the weight of the solar power units.

Q4. What is the daily energy generated by a solar power plant with a capacity of 1 kWp?

A 1 kWp solar power plant may generate 4 to 5.5 units per day on a clear sunny day.

Q5. Will I get the same amount of energy from the RTS all year?

No, the RTS’ daily energy generation is reliant on multiple factors, including temperature and solar irradiation, which may not be consistent.

Q6. Will the RTS provide me with the same amount of annual energy for the next 25 years?

No. When solar modules are exposed to sunlight and the outside environment for a significant amount of time, they start to lose their generation capacity. This is referred to as deterioration.

Q7. What is the rate at which the total cost of the solar rooftop plant is determined?

Consumers are urged to pay just the rates set by the DISCOMs (L1 rates). If any vendors charge a higher price than the rates set by DISCOMs for domestic users, consumers will be intimated.

Q8. Is there any support or subsidy from the state government for solar panel subsidy?

You can get more details about the rooftop solar distribution firms at

Q9. What are my options for paying the Electricity Distribution Company (DISCOM)?

DISCOM will create a charge based on the reading provided by the net meter installed at the consumer’s premises because the system is grid-connected through net metering. Only the net units (total imported units minus exported solar units) will be charged to the consumer.

Q10. What are the different models for putting rooftop PV systems in place?

CAPEX Model: In this model, the consumer owns the system and is responsible for its costs. The entire system is owned by the third-party project developer in the RESCO model. The consumer only purchases the generated energy by paying a monthly fee determined by the Power Purchase Agreement (PPA). The developer is also responsible for O&M over the system's lifetime (25 years).

Q11. If I live in a rental house, can I still install a rooftop solar system?

The rooftop solar system can be deployed by the electrical customer under any framework, such as net or gross metering. So, if you have an electrical connection in your name, obtain permission from the owner to use the roof for solar rooftop installation.

Q12. Where can I buy solar panels?

To buy solar panels, go to the Adani Electricity website and select Roof Top Solar under More Information tab.
