INOX Air Products Private Limited (INOXAP) entered into a long-term partnership with Insolation Energy Limited’s subsidiary, Insolation Green Energy Private Limited (INA Solar), to supply ultra-high purity (UHP) Nitrogen. In a press release, the firm said the collaboration also supports INOXAP’s efforts to power the growth of emerging industries including solar energy, semiconductors, and electronics. 
In a press release, INOXAP, an industrial, electronic & specialty gas manufacturer, said it would supply power through a direct pipeline at 2,400 Nm3/hrto its 4.5 GWSolar Cell manufacturing facility being set up at Narmadapuram, Madhya Pradesh. Under the agreement, INOXAP will invest in and develop a pipeline network from its existing Air Separation Unit (ASU) in Narmadapuram to ensure reliable supplies.
Previously, Insolation Energy had shared the firm’s plans to begin commercial production of solar cells from September 2026. Abhishek Kaushal, Chief Business Officer (CBO) of the listed firm, in an interview with Saur Energy. Kaushal said that the firm will commission a 4.5 GW TOPCon solar cell manufacturing facility later this year.  
INOXAP will provide UHP Nitrogen to advance manufacturing processes at the Narmadapuram facility. The direct pipeline supply would aim to ensure a reliable and consistent flow of high-purity nitrogen essential for maintaining stringent quality standards in solar panel production.
Ultra-high purity (UHP) nitrogen is an essential process gas used throughout solar cell manufacturing to create an oxygen- and moisture-free environment during critical production stages such as silicon wafer diffusion, thin-film deposition, annealing, metallization, and contact firing. By preventing oxidation and contamination of silicon wafers and metal contacts, UHP nitrogen helps maintain precise process conditions, improves cell efficiency, increases production yield, and ensures the consistent quality of advanced solar cell technologies such as PERC, TOPCon, and HJT. Even trace amounts of oxygen or moisture can introduce defects, making UHP nitrogen a critical utility in modern gigawatt-scale solar cell factories.
Previously, companies like INOX Air Products (INOXAP) entered into a long-term partnership with Grew Energy Private to supply ultra-high purity (UHP) nitrogen for Grew Energy’s upcoming 3 GW Solar PV Cell manufacturing facility at Narmadapuram, Madhya Pradesh.
Similarly, INOX Air Products Private Limited (INOXAP) has also entered into a long-term partnership with TACC Limited (The Advanced Carbons Company) (TACC) to supply Nitrogen through an on-site nitrogen plant.  INOX Air Products would use the nitrogen for its upcoming greenfield manufacturing facility in Dewas, Madhya Pradesh, India. It would set up the Nitrogen plant on a Build, Own, and Operate (BOO) basis, ensuring a consistent, safe, and high-purity nitrogen supply aligned with TACC’s manufacturing needs.
Speaking about the partnership, Diganta Sarma, Head – Strategy & Business Development, INOX Air Products, said, “Through this long-term agreement, INOX Air Products intends to leverage its existing capabilities in Narmadapuram and make significant investments in dedicated pipeline infrastructure to ensure a reliable supply of ultra-high-purity nitrogen for advanced solar panel manufacturing.”
Vikas Jain, Managing Director, Insolation Green Energy Private Limited, added, “At INA Solar, we are committed to advancing India’s clean energy ambitions through world-class solar panel manufacturing capabilities. Our partnership with INOXAP strengthens this foundation by securing a dependable supply of ultra-high-purity nitrogen, an essential component in our manufacturing processes.”
