We are exploring R&D for perovskite-silicon tandem cells: Ahaan Solar

Ahaan Solar is a next-generation solar module manufacturer, built on the legacy and expertise of Airox Nigen—India’s trusted name in industrial gas and hydrogen systems since 1994.

As the renewable energy division of Airox Nigen, Ahaan Solar combines proven industrial engineering experience with a future-focused approach to clean energy. Our mission is to manufacture world-class, high-efficiency solar modules in India, for both domestic and global markets.

With state-of-the-art automation, certified quality systems, and a strong foundation in precision manufacturing, we are driving India’s clean energy ambitions forward—one panel at a time.

Aniruddh Agrawal Founder of Ahaan Solar, tells us more. Excerpts from an interview: 

DQ: What inspired you to venture into solar module manufacturing? How does this complement your parent company Airox Nigen's hydrogen expertise?

Aniruddh Agrawal: The inspiration came from a strategic vision to build an integrated clean energy ecosystem. Airox Nigen has been at the forefront of hydrogen generation technology for over three decades. As green hydrogen production relies heavily on clean electricity, solar became a natural extension. 

Ahaan Solar was founded to complement Airox’s green hydrogen mission by providing efficient, high-quality solar modules entirely manufactured in India. Together, we are building a vertically integrated renewable value chain that spans from solar power generation to hydrogen production, storage, and application. It’s about bringing synergy between two technologies that are crucial to India’s decarbonization and energy independence goals.

DQ: The Rohnat Renewable Energy Park houses your 2 GW solar module manufacturing project. Can you walk us through the scale, milestones, and impact of this initiative?

Aniruddh Agrawal: Our 17-acre facility in Rohnat, Haryana, is more than a factory, it's a clean energy blueprint. In Phase 1, we’re launching a 600 MW line by mid-2025, with advanced automation and precision engineering capabilities. The full-scale 2 GW capacity will be completed in phases over the next few years. 

This project directly aligns with India’s National Solar Mission and the Make in India initiative by reducing reliance on imported solar components. We expect to generate hundreds of jobs, stimulate regional manufacturing, and supply high-efficiency modules for both domestic projects and exports. It's our way of contributing tangibly to India's renewable energy roadmap.

DQ: Ahaan Solar is deploying advanced TOPCon technology in its modules. How do this innovation enhance the efficiency and sustainability of your solar products?

Aniruddh Agrawal: We have chosen TOPCon because they represent the cutting edge of solar efficiency and long-term performance. TOPCon cells offer higher conversion efficiencies and lower degradation, making them ideal for India's high-irradiance conditions. It also combines the best of crystalline and thin-film technologies, ensuring better performance in low-light and high-temperature environments. 

Both technologies extend module lifespans and reduce the Levelized Cost of Electricity (LCoE) over time. These innovations make our modules more sustainable, not just in terms of energy output, but also in resource use, recyclability, and reliability across varied geographies.

DQ: How does Ahaan Solar integrate cutting-edge technology and sustainable practices throughout your manufacturing process?

Aniruddh Agrawal: Sustainability is embedded in our DNA, because of our history with Airox Nigen. Our facility is designed to optimize water and energy consumption using closed-loop systems and rooftop solar integration. Automation and AI-driven quality control ensure minimal material wastage and consistent output. 

We are sourcing raw materials with transparency and focusing on reducing our overall carbon footprint during production. Our R&D team is also working on low-lead soldering and glass recycling initiatives to further green our supply chain. This approach doesn’t just help the planet; it ensures customers receive durable, high-performance modules built with responsibility and care.

DQ: With operations slated to commence by the end of-2025, what are your production targets for both domestic and international markets? How do you plan to scale beyond the initial 600 MW capacity?

Aniruddh Agrawal: Our initial 600 MW line is expected to be operational by the end of 2025, primarily serving domestic demand for utility-scale and rooftop solar projects. Post-commissioning, we aim to ramp up to 1.2 GW within the next 18 months and achieve full 2 GW capacity within the next few years. 

Export markets, especially in Asia and Africa, are part of our growth roadmap. We are building strategic partnerships to establish supply channels globally, supported by our location in Haryana with access to major logistics corridors. Scalability has been integrated into our design, expansion will be modular and swift, with additional lines already planned.

DQ: How does Ahaan Solar address the challenges of India’s diverse climatic conditions and grid requirements?

Aniruddh Agrawal: India's climatic diversity from scorching deserts to humid coastlines demands rugged solar solutions. Our modules undergo stringent thermal cycling, humidity freeze, and PID testing to ensure performance under extreme conditions. TOPCon technologies provide better heat tolerance and low-light efficiency, critical for regions with fluctuating weather. 

On the grid side, we are aligning our products with future inverter compatibility, ensuring better yield and grid stability. Additionally, our R&D team is working on bifacial modules and floating solar-compatible solutions, which will further optimize performance across India's varied terrain and energy demand patterns.

DQ: What role do you see Ahaan Solar playing in India's goal of achieving energy independence? How does your facility contribute to reducing dependency on imported components?

Aniruddh Agrawal: India currently imports a large share of its solar components, making the sector vulnerable to global price and supply shocks. Ahaan Solar aims to reverse that trend. By manufacturing high-efficiency solar modules domestically, we are not only supporting India’s energy independence, but also creating a resilient solar supply chain. 

Our facility uses primarily Indian-made or locally sourced materials, wherever feasible, and we are investing in developing an in-house cell manufacturing capability in the future. Our long-term vision is to become a self-sufficient and export-ready solar technology player that strengthens India’s position in the global clean energy economy.

DQ: Looking ahead, what are your expansion plans for Ahaan Solar? How do you envision the company contributing to India’s transition toward a sustainable and energy-secure future?

Aniruddh Agrawal: Ahaan Solar’s mission is to become a cornerstone of India’s solar growth story. Beyond scaling module capacity to 2 GW, we are exploring backwards integration into cell manufacturing, R&D for perovskite-silicon tandem cells, and solar-plus-storage applications. 

We also aim to offer solar EPC services for hydrogen projects and remote microgrids. By 2030, we hope to be part of at least 5 GW of installed solar capacity across India and partner with developers worldwide. Our goal is simple: to power India’s clean energy journey with world-class solar solutions built right here, in India, for the world.
