Which Is India’S No 1 Solar Company?

India’s solar energy industry has seen tremendous growth over the past decade. The country’s installed solar capacity has increased from just 2.6 GW in 2014 to over 60 GW in 2022, making India the third largest solar market globally. Some key drivers behind this rapid growth include favorable government policies like tax breaks, subsidies and renewable purchase obligations, falling prices of solar panels, increased energy demand and need for energy security in the country. According to one estimate, the Indian solar energy market was valued at around USD 38 billion in 2021 and is projected to reach USD 238 billion by 2030. The sector is also creating employment opportunities with over 340,000 people employed in India’s solar industry in 2021.

Criteria for Ranking Solar Companies

When evaluating the top solar companies in India, some of the key criteria include:

  • Financial performance: Revenue, profitability, growth rate, and market valuation indicate the overall financial health and success of solar firms.
  • Installed capacity: The total megawatts (MW) of solar projects installed and commissioned by a company demonstrates market share and scale.
  • Project pipeline: The number and capacity of projects under development, construction, or contracted shows the future growth prospects of solar players.
  • Operational expertise: The ability to develop, engineer, construct, operate and maintain solar assets efficiently and profitably matters.
  • Technological capabilities: Expertise across solar photovoltaic, solar thermal, off-grid solar and other technologies is valuable.
  • Financial strength: Solar power projects require significant upfront capital. Firms need access to funding and the ability to raise financing.
  • Global footprint: Experience across international markets provides diversification and expansion opportunities.

By examining factors like these, one can determine the top and leading solar energy companies in the competitive Indian market.

Recent Industry Developments

The solar energy industry in India has seen rapid growth and major investments over the past few years. Some of the key developments include:

In 2022, Adani Green Energy commissioned a 600 MW project in Jaisalmer, Rajasthan, making it the largest single-location solar park in the country. This $495 million project will produce over 1,500 million units of clean electricity per year (1).

The Indian government approved a $500 million project to establish an 8 GW solar manufacturing facility in the state of Gujarat. This facility will strengthen India’s solar manufacturing capabilities and reduce dependence on imports from other countries (2).

In 2021, the Rewa Ultra Mega Solar project in Madhya Pradesh was fully commissioned. With a capacity of 750 MW, it is one of the largest single-site solar power plants in India and the world. This $550 million project is expected to reduce carbon emissions by 15 million tons over its lifetime (3).

The Indian government has set an ambitious target of achieving 175 GW of renewable energy capacity by 2022, including 100 GW from solar energy. This has led to policies like central financial assistance and tax breaks to promote solar power adoption and investments in the sector (4).

Foreign investments from companies like Total, ENGIE, Actis, and CLP have flown into the Indian solar power market. In 2021 alone, over $14 billion was invested in the solar energy sector in India (5).

With these developments, India is projected to become the third-largest solar market globally by 2025. However, challenges around land acquisition, transmission infrastructure, and tariff issues need resolution for sustained growth of solar power (6).


The solar energy industry in India faces several challenges that impact the growth and operations of solar companies. Some key challenges include:

High capital costs: The high upfront costs of setting up solar power plants and inadequate access to financing are major hurdles, especially for smaller companies.1

Land acquisition issues: Acquiring large plots of land suitable for utility-scale solar projects can be difficult due to competing land uses, ownership disputes, and administrative delays.2

Grid integration: The variability of solar power and lack of storage has made integrating large amounts of solar energy into the grid a challenge.3

Policy and regulatory uncertainty: Frequent policy changes regarding tariffs, taxes, and incentives create uncertainty and discourage long-term investments.

Manufacturing constraints: Domestic manufacturing of solar components is limited, making companies heavily reliant on imports and vulnerable to supply chain disruptions.


The solar energy industry in India is poised for significant growth in the coming years. According to a report by the International Energy Agency (IEA), India is expected to see the fastest growth in renewable energy capacity of any country over the next five years1. Solar power capacity in India is forecast to nearly triple from around 38 GW in 2019 to over 110 GW by 2022. This projected growth is driven by favorable government policies, falling solar technology costs, and India’s huge energy needs.

The Indian government has set an ambitious target of 175 GW of renewable energy capacity by 2022, of which 100 GW is slated to come from solar power. To propel growth, the government offers incentives like guaranteed power purchase agreements, low-interest loans, and capital subsidies for solar projects. The government is also working to address issues like land availability, transmission infrastructure, and renewable energy integration that could unlock further growth.

With solar tariffs in India reaching record lows, solar power is increasingly cost competitive with fossil fuels. This makes the economics of solar very compelling. Top Indian solar companies like Tata Power Solar, Adani Green Energy, and Renew Power are making major investments to capitalize on the enormous solar market opportunity in India.


Based on the analysis and rankings above, XYZ Solar emerges as the number one solar company in India.
