The Indian government has big ambitions when it comes to the renewable energy sector, especially solar power. The goal is to take the country’s solar power generation capacity to 280 GW by 2030.

To achieve this mammoth target, the rooftop solar sector is going to play a crucial role.

However, this sector has a huge dependency on businesses and private consumers to invest in solar and allow installations on their rooftops. To incentivize private consumers, the Indian government offers financial help to homeowners and housing societies installing an on-grid rooftop solar system in form of subsidies.

In addition, to make solar investment cheaper and reduce its dependencies on foreign imports, India also plans to ramp up the domestic manufacturing of solar modules and cells. In order to realize this plan, the Indian government has announced Rs 18,500-crore (~US$2.31 billion) performance-linked incentive (PLI) scheme for solar cell/module manufacturers.

The good news is that with these government interventions along with the motivation to reduce energy bills and carbon footprint, rooftop solar installation in India has seen promising growth in the last 6 years.

The country has achieved more than 8 gigawatts of rooftop solar installations by December 2022.

Having said that, it is much less than what the Government targeted and there is a lot of scope in the rooftop solar market in India.

To take forward India’s solar ambitions, apart from the major business conglomerate, Indian startups will also have a huge role to play. Here is the list of rooftop solar companies in India that are providing customers with innovative choices to transition to a greener future.

Solar Square

Solar Square is a solar solution provider to homeowners, residential societies, and commercial buildings. The company is into solar design & installation, finance, and after-sales service, for commercial places, residential societies, and private homes.

Founded in 2015 by IIT Mumbai alumni, the startup started as a commercial rooftop solar provider and in 2020 decided to venture into the residential segment. Solar Square provides modular prefabricated solar designs that considerably reduce the installation time for residential use.


Sunday Grids

Sunday Grids is a digital solar company that solves the problem of users who live in rented apartments and have no access to install on the roof. The Bengaluru-based startup gets solar systems installed on commercial properties (host sites) that partner with them, and the host of the system pays a fixed price for the power.

The payments made by hosts are converted to credits and sold to any residential customers on the Sunday Grids platform. Customers can then use these credits as discounts or vouchers on their power bill while paying through bill payment channels.

From industrial factories to malls, schools, and hospitals, any commercial establishment can become a host and in turn, save their energy bills without investing huge capital for solar installations.


Freyr Energy

Freyr Energy offers rooftop solar installations to residential, commercial, and industrial customers. Established in 2014, the Hyderabad-based startup works with more than 350 channel partners across India.

The company has introduced a mobile app SunPro+, which helps the Freyr Energy sales team and channel partners to implement and design solar installations. The app helps consumers record the entire solar journey, from exploration to ownership. The app generates a quote for solar installation, tracks the progress of implementation, and monitors the performance of the solar system.



Oorjan partners with solar brands in India to provide solar installations. The Mumbai-based company design, finance, and implement rooftop solar installations, and provide lifetime performance monitoring through an IoT system that helps track the performance of the solar power system remotely and also data analysis.

Oorjan is another rooftop solar company that is founded by IIT Mumbai alumni in 2014. Since then the company has acquired 2500+ customers across 18 states and Union Territories.


Power Tree

Power Tree is one of the unique rooftop solar companies in India that are not into typical solar panels but develop Solar Tree. The Gandhinagar-based company invents, designs, engineers, and manufactures Solar Tree.

The unique design of the tree helps to generate electricity but also save huge space consumption problem. Solar trees can be installed on industrial premises, government sites, over a parking lot, in parks, and in a residential society among other applications.

Apart from solar trees for commercial and business needs, the company also has solar trees for rooftops. These rooftop solar trees are portable and foldable, which makes it easy for the user to carry them from one place to another.

Starting in 2018, the company has multiple design patents for various innovative designs of Solar Tree.
