“We are investing around INR 125 crore to set up the plant. The facility is expected to begin operation in December 2025,” said Prayag Vansjaliya, Managing Director, Atal Solar to Energetica India.
He further added that the plant will mainly produce TOPCon solar modules, which are popular for their good efficiency and wide use in the market. “At the same time, the plant is being built to be future ready so that we can easily upgrade to newer technologies like HJT or Back Contact later on. The machines and layout are flexible, so we can add or change equipment when needed. We will be using advanced automation and quality systems that work well with both current and future module types,” said Vansjaliya.
The fully-automatic solar module plant will deploy automation technologies like robotics, IoT, advanced vision systems and manufacturing execution systems (MES). “Robotic arms will handle delicate accurate task in cell placement (robotic layup), soldering, and material transfer with high precision, reducing damage and increasing speed. Connected devices and sensors will monitor equipment performance, energy consumption, and environmental conditions in real time, providing valuable insights for optimisation and predictive maintenance,” shared Vansjaliya.
He further added that it will also have high-resolution cameras – detecting microscopic defects like microcracks, surface irregularities, and cell misalignment with exceptional accuracy, often exceeding human capabilities. “Manufacturing Execution Systems (MES) will integrate various aspects of the production line, including quality control robots and production parameters, allowing for real-time monitoring and adjustment based on QC findings and enabling detailed documentation for traceability,” he said.
Vansjaliya asserted that the technological edge lies in the seamless integration and synergistic operation of these advanced technologies, leading to a more efficient, cost-effective, and higher-quality solar panel manufacturing process. “This ultimately allows the production of more reliable and durable solar products, making solar energy more accessible and affordable,” he stated.
Talking about the attractiveness of the solar manufacturing sector, Vansjaliya asserted that the government is providing impetus on ramping up GW-scale manufacturing units, boosting R&D in solar technology, and ensuring financing options to make the sector more attractive to investors.
As India aims to achieve 500 GW of non-fossil fuel capacity by 2030, and a significant chunk of that is expected to come from solar. “Over the next 3-5 years, India is likely to see a rise in vertically integrated solar manufacturers, where companies handle everything from wafer production to panel assembly. This will reduce costs and improve efficiency,” stated Vansjaliya.
He further added that to reduce the dependency on China, in the next 3-5 years, and India will focus on ramping up domestic capacity for raw materials like silicon and aluminium, as well as other components like inverters and batteries.
Talking about the company’s future plans include scaling module capacity and initiate cell-line planning within the next one year. “In the medium term (1-3 years), we would like to start cell-line commissioning and pilot production and in the long term (3-5 years), we would like to develop integrated storage manufacturing and expand cell/wafer capabilities,” shared Vansjaliya.
