Just ten years ago, India's solar story was only beginning, with panels limited to a few rooftops and desert projects.
Fast forward today, the country has achieved a historic milestone, India has overtaken Japan to become the world's third-largest solar power producer.
As per the International Renewable Energy Agency (IRENA), India generated +1,08,494 GWh of solar power, surpassing Japan's 96,459 GWh.
The country's solar capacity has also grown rapidly, touching 119.02 GW as of July 2025.
This includes 90.99 GW from ground-mounted plants, 19.88 GW from rooftop systems, 3.06 GW from hybrid projects, and 5.09 GW from off-grid installations-showcasing India's diversified approach to renewable energy.
On the manufacturing front, India is building a strong solar ecosystem. In just one-year, solar module capacity nearly doubled from 38 GW in March 2024 to 74 GW in March 2025, while solar PV cell capacity surged from 9 GW to 25 GW.
India marked a big milestone with its first 2 GW ingot-wafer facility, strengthening self-reliance and cutting import dependence.
With solar energy now at the heart of India's clean energy push, it's no surprise that investors are eyeing opportunities in this space.
In this article, we take a look at some of the top solar energy stocks in India, shortlisted from Equitymaster's screener of the Best Solar Energy Stocks in India.

Now that we've identified the top solar stocks in India, let's take a closer look at a few of these companies to understand their business operations.
As India's largest solar module manufacturer, Waaree Energies boasts a robust 12 GW production capacity, supported by four advanced manufacturing facilities. The company provides a diverse range of solar solutions, including modules, inverters, batteries, and rooftop solar systems.
Waaree Energies specialises in manufacturing solar PV modules using multi-crystalline and monocrystalline cell technologies, along with innovations such as Tunnel Oxide Passivated Contact (TopCon).
Additionally, it produces semi-flexible solar panels for global customers, catering to a wide market through direct enterprise sales.
As a vertically integrated player, Waaree further strengthened its manufacturing capabilities by acquiring Indo Solar, adding 5.4 GW to its capacity.
It is also the largest Indian exporter of solar modules with 10+GW of solar modules supplied to more than 20 countries.
Also, Indian solar PV manufacturer Waaree Energies Limited has announced plans to spread out some of its planned 6 GW integrated solar manufacturing in Odisha to multiple locations within India.
Waaree's 6 GW plans for Odisha comprised establishing ingot, wafer, solar cell and module manufacturing capacity, to be financed from Rs 30 billion (bn) raised via an initial public offering (IPO).
The management explained that the decision is aimed at accelerating project momentum, optimising resource utilisation, and ensuring timely execution in line with its IPO objectives, as it experiences delays at the current location.
Out of the 6 GW integrated planned capacity, 3 GW of module capacity will be diverted to Samakhiali in Gujarat, 3 GW module capacity to Gujarat/Tamil Nadu or any other location, 6 GW solar cell capacity to Unn in Gujarat, and 6 GW ingots and wafers at Nagpur in Maharashtra.
This distribution will not significantly impact its overall project cost, which is estimated at Rs 90.5 bn (US$1.04 bn).

India's solar energy capacity is expanding at a remarkable pace. From around 79?GW today, the country aims to reach nearly 195?GW in the next five years. With the sector growing at nearly 20% annually, solar has become one of the fastest-growing energy industries in India.
Government initiatives like the National Solar Mission, along with state-level programs, are driving large-scale solar projects and boosting domestic manufacturing. This policy support creates a favourable environment for solar companies and adds confidence for investors.
Solar energy isn't just clean and eco-friendly-it's a smart, future-ready investment. Many Indian solar companies lock in long-term power purchase agreements (PPAs) with state agencies, which means predictable, steady revenues.
Solar technology is advancing fast, and older products can quickly become outdated. The companies that fail to innovate, may risk losing their competitive edge.
Shifts in government rules or policies can affect how solar companies perform. This can impact the profitability of the company.
Solar companies in India still compete with coal, oil, and gas, which remain major sources of energy in India.
India's renewable energy sector is gaining momentum, driven by focused policies and strategic planning at the national level.
As part of its COP26 commitments, India is working toward generating 500?GW of electricity from non-fossil fuel sources by 2030.
The country's geography gives it a natural advantage in solar energy. Located in the tropical region, with the Tropic of Cancer passing through several states, India has high solar potential, estimated at 748?GW.
States such as Rajasthan, Jammu & Kashmir, Maharashtra, Madhya Pradesh, and Andhra Pradesh stand out as key contributors to solar growth, providing ample opportunities for both energy generation and investment.
The sector has already shown impressive growth. By July 2025, India's solar power capacity had increased by 4,000%, pushing the total renewable energy capacity to 227?GW.
Palli village in Jammu & Kashmir became India's first carbon-neutral panchayat, running entirely on solar power-showing how solar energy can be implemented successfully at a local level.
Strong government support, vast solar potential, and ongoing technological innovation make solar stocks a compelling option.
At the same time, investors should be mindful of market swings, policy changes, and project execution risks that could affect their returns.
The growth of India's solar sector is being strongly supported by government initiatives and policy measures.
Under the National Renewable Energy Mission, investments in both large-scale and decentralised projects are set to rise. Strengthening of the solar grid with Rs 15 bn and the extension of the Production-Linked Incentive (PLI) scheme further boost domestic solar manufacturing and reduce reliance on imports.
Requirements for using Indian-made panels in major schemes, along with the basic customs duty on imports, are boosting local solar manufacturing. At the same time, companies remain exposed to global price swings for key materials.
Investors should evaluate the company's fundamentals, corporate governance, and valuations of the stock as key factors when conducting due diligence before making investment decisions.
