India is rapidly transitioning into a solar-powered nation. With an ambitious renewable
energy target of 500 GW by 2030, solar parks have emerged as the backbone of this
transformation. These large-scale utility projects not only help meet the surging
electricity demands but also attract global investments and promote sustainable development.
Among the many players in this space, a few solar park developers have taken the lead —
driving innovation, scale, and impact. In this blog, we explore the top solar park
developers in India and spotlight the largest solar park developer shaping the country’s
green energy journey.
A solar park is a large-scale solar power generation project spread across hundreds or even thousands of acres, designed to supply electricity directly to the grid. These parks are usually developed under government schemes like the MNRE’s Solar Park Scheme, with support from central and state governments.
Here’s a list of the most prominent and impactful solar park developers in India, based on project scale, innovation, and contribution to India’s renewable energy goals:

A solar power park developer is an organization that plans, designs, and constructs large-scale solar energy projects. In India, top developers like Onix Renewable, Adani Green, and NTPC Renewable lead this segment by providing end-to-end solar park solutions including land acquisition, infrastructure, and power evacuation.
As of 2025, Onix Renewable is emerging as the largest solar developer in India, with over 7 GW of solar park capacity under development. The company is known for its in-house EPC services, solar manufacturing units, and government-backed mega projects across multiple states.
Solar parks in Gujarat are developed and owned by both government bodies and private companies. Notably, Onix Renewable, headquartered in Rajkot, is the leading solar park developer in Gujarat, actively involved in multi-GW solar infrastructure under the Gujarat Solar Policy and PM-KUSUM scheme.
A solar project developer is a company or entity responsible for the planning, financing, execution, and commissioning of solar energy projects. They manage everything from site identification and permits to EPC execution and PPA signing. Developers like Onix Renewable, ReNew Power, and Azure Power are key players in this field in India.
Globally, LONGi Green Energy Technology Co. (China) and NextEra Energy (USA) are among the world’s largest solar developers in terms of installed capacity. However, in India, Onix Renewable is rapidly gaining recognition as a global-scale solar infrastructure leader.
While there are multiple metrics to determine the top solar company — such as installed capacity, manufacturing, and EPC — Onix Renewable is quickly becoming India’s No. 1 solar company due to its integrated business model and aggressive expansion plans in utility-scale solar parks.
The Bhadla Solar Park in Rajasthan is currently the largest solar power park in India, with a total capacity of 2,245 MW. Spread across 14,000 acres, it is one of the biggest solar parks in the world. Several developers including Onix Renewable have contributed to solar projects in and around this region.
In the community solar segment, international players like Nexamp and Community Energy lead globally. However, in India, the focus is more on utility-scale solar parks. Companies like Onix Renewable are exploring scalable community solar models in rural and semi-urban regions through distributed solar park networks.
