Que: Could you share the journey of JRST, its core technological expertise, and your vision for supporting India's rapidly expanding solar manufacturing ecosystem, particularly in upstream technologies such as silicon ingots and wafers?

Ans: JRST was built from the ground up, starting with the most basic material in the chain: quartz. Our team spent years learning the full silicon chain hands-on, from the quartz stone to high-purity sand, crucibles, ingots and wafers, and ran a crystal-growth operation abroad for about three years before bringing that experience home. In India we proved it first: our team produced Maharashtra's first pilot mono ingot batch, and our sister company, Silicon Ingot Technology, runs a commissioned ingot plant. Our vision is simple: India has built large cell and module capacity, and the next step is to make the silicon underneath it here. We want to be the team that makes that happen.

Que: We understand that JRST is expected to announce a significant partnership with a listed Indian solar manufacturer for a new silicon ingot and wafer manufacturing facility. Could you share details of this collaboration, including the proposed manufacturing

Ans: We are in advanced discussions with several Indian groups on new ingot and wafer capacity, including one listed company. Until agreements are signed, it would not be right to share capacity, investment or timelines. What I can say is that our role in these projects is end-to-end: feasibility and plant blueprint, equipment selection, installation, commissioning and ramp-up, with our team on the ground until the line runs to specification.

Que: Silicon ingot and wafer manufacturing requires advanced technology, precision engineering, and consistent quality. What technological solutions and turnkey capabilities does JRST offer, and how will these help Indian manufacturers achieve globally competi

Ans: Ingot and wafer manufacturing is unforgiving. Yield is decided by details: the right quartz and crucible, hot-zone design, pulling recipes, and wafering consumables. JRST brings working know-how across the whole chain, not just equipment supply. We take a project from blueprint to stable production, and we support it afterwards with spares, consumables and process support, so that Indian plants can match international yield and quality benchmarks.

Que: India is rapidly expanding its solar cell and module manufacturing capacity, but upstream manufacturing remains a critical area for development. How do you see the domestic ingot and wafer industry evolving over the next five years, and what opportunities

Ans: Over the next five years, upstream manufacturing will move from an ambition to a requirement. ALMM List-III for wafers takes effect from June 2028, and new export controls on ingot and wafer technology abroad make it clear that India cannot rely on imported wafers or imported know-how indefinitely. We expect a wave of ingot-wafer plants, and with it demand for the skills, equipment, materials and services to run them. That is precisely where JRST sits.

Que: With increasing investment in India's solar manufacturing sector, what is JRST's strategy for expanding its presence in the Indian market? Are you exploring additional partnerships, technology collaborations, or turnkey manufacturing projects wi

Ans: We work across India and are deliberately building a full-stack offering. It starts with plant blueprints that give investors and manufacturers everything they need to make a clear go / no-go decision on entering this industry: technology choices, equipment, capex and operating costs, raw-material strategy, timelines and returns. It then continues through turnkey execution and an ongoing supply of critical spares and consumables. We are also building India's capability in high-purity quartz, the starting point of the whole chain. We are open to the right collaborations with manufacturers who share a long-term view of upstream self-reliance.

Que: Looking ahead to 2030, what are JRST's key growth priorities in terms of technology innovation, manufacturing projects, and international expansion? How do you envision JRST contributing to India's ambition of becoming a globally competitive sol

Ans: Four priorities. First, delivering ingot-wafer plants in India that run to specification. Second, building an indigenous crystal-growth machine: we have a plan to develop India's own ingot puller, so that the heart of the ingot line is also made in India. Third, deepening the supply chain behind these plants: high-purity quartz, crucibles and consumables. Fourth, taking Indian upstream capability to markets such as the Middle East. Our contribution to India's ambition is to make sure the know-how stays and grows here.

Que: With JRST potentially playing a key role in establishing a new silicon ingot and wafer facility in India, what will be the major technical and operational challenges in executing this project? How will the collaboration contribute to technology transfer,

Ans: The main challenges are not the machines; they are process stability, skilled people and a dependable supply of critical materials. That is why we put our own team on every line through ramp-up and train local operators and engineers until they can run it themselves. Every plant we help build means skilled jobs, knowledge that stays in India, and fewer imported wafers.
