Adani Group’s Mundra Solar Technology Limited has contracted a Government of India enterprise Engineers India Limited (EIL) to build its 30,000 metric tons per annum (MTPA) polysilicon and 500 MTPA monosilane project.

Polysilicon is the most critical part of a solar cell whose production currently doesn’t exist in India. Monosilane or SiH4 is a feed gas to produce polysilicon.

EIL said it will provide owner’s engineer services for these projects for Mundra Solar which is a group company of Adani Enterprises Ltd. It stated, “Conventionally, India has been dependent on import of polysilicon and this would be a step towards realizing the vision of Atmanirbhar Bharat. This would also contribute towards nation’s target of Net Zero by 2070.”

It did not share any more details about the cost or deadline of these facilities.

Polysilicon is central to Adani’s multi Gigafactory plans, one each for solar modules, wind turbines and hydrogen electrolyzers by 2030. The solar PV facility will be a vertically integrated fab from polysilicon to modules (see Adani Announces 3 Green Giga Factories In India).

Adani aims to set up a large-scale integrated manufacturing plant in Gujarat’s Gulf of Kutch comprising 31,000 metric tons (MT) polysilicon for an estimated cost of INR 73.81 billion ($892 million) on 57.09 hectares of land owned by the group.

India’s Production Linked Incentive (PLI) scheme for vertically integrated solar PV manufacturing is encouraging companies to devise plans to enter/expand their presence in the space, beyond cell and module manufacturing alone (see India Launches PLI Tranche II Solar Manufacturing Tender).
