How to Setup a Solar Power Plant in India 2025- Step-by-Step Guide
India is one of the world's leading markets for solar energy, with ample sunlight available throughout the year. The decreasing cost of solar photovoltaic (PV) panels and advancements in solar plant installation technology have made solar energy more cost-effective than non-renewable energy sources. As of 2025, solar power is one of the most viable renewable energy options, contributing largely to India's energy goals.
Setting up a solar power plant in India can be a highly profitable business opportunity, whether for commercial, industrial, or agricultural purposes. This guide provides a detailed roadmap on how to set up a solar power plant, covering market research, business registration, licensing, investment, and costs.
Understanding Solar Power Plants
What is a Solar Power Plant?
A solar power plant converts sunlight into electricity using photovoltaic (PV) panels or solar thermal systems. Large-scale solar farms feed electricity into the grid, while smaller solar energy plants cater to localized energy needs.
Types of Solar Power Plants:
- Utility-Scale Solar Power Plants: Large solar farms connected to the grid.
- Rooftop Solar Systems: Small-scale installations for homes and businesses.
- Hybrid Solar Systems: Solar integrated with other renewable energy sources.

Profitability & Return on Investment (ROI)
Profit margins from a solar power plant in India can be substantial, with a large solar power plant generating significant revenue annually.
- A 5 MW solar plant generates ~6000 MWh annually.
- Estimated revenue: Rs. 1.5 - 1.75 crore per year.
- Payback period: ~7-10 years depending on location and incentives.
Big Solar Power Plants in India
India is a global leader in solar energy production, with several big solar power plants contributing significantly to the country's renewable energy goals. Some of the largest solar power plants in India include:
- Bhadla Solar Park (Rajasthan): With a massive capacity of 2.25 GW, Bhadla Solar Park is one of the largest solar plants in the world. Located in the arid Bhadla region of Rajasthan, it benefits from high solar irradiance, making it an ideal location for solar power generation.
- Pavagada Solar Park (Karnataka): This big solar plant in India has an installed capacity of 2.05 GW, spanning approximately 13,000 acres. The project follows a unique land-lease model, where local farmers lease their land for solar power generation, ensuring both sustainability and economic benefits.
- Rewa Solar Power Project (Madhya Pradesh): With a capacity of 750 MW, the Rewa Solar Power Project is one of India's first large-scale solar projects to achieve grid parity. It supplies clean energy to both the state of Madhya Pradesh and the Delhi Metro Rail Corporation, showcasing the viability of large-scale solar power in reducing dependency on fossil fuels.
Conclusion
With India's push towards renewable energy, investing in a solar power plant in India is a highly profitable opportunity. Using modern solar power software like ARKA 360 can streamline the planning, design, and optimization of solar power systems, ensuring maximum efficiency and ease of deployment.
This technology helps solar businesses manage everything from system designs to financing options, making it easier to stay competitive in the rapidly growing market.
