Adani Solar becomes India’s sole producer of large-sized monocrystalline silicon ingots


Adani Solar, the photovoltaic manufacturing and research arm of the Adani Group, has become India’s sole producer of large-sized monocrystalline silicon ingots for M10 and G12 wafers.

The ingots were unveiled by Gautam Adani, chairman of Adani Group, at their Mundra facility recently. “These monocrystalline ingots will drive indigenization to produce renewable electricity from silicon-based PV modules with efficiencies ranging from 21% to 24%,” stated the company.

Adani Solar is a part of Adani New Industries Ltd (ANIL), which strives to develop the world’s largest green hydrogen ecosystem. It completed the backward integration of ingot line infrastructure in a record time of about 7 months.

The new manufacturing line will produce silicon ingots exclusively for Adani solar wafers, cells, and modules production.
While the company’s initial production has already begun, it intends to add 2 GW of ingot and wafer capacity by the end of 2023. By 2025, it will scale up to 10 GW.

“We have made remarkable technological progress in every aspect of solar manufacturing in the past, from cells to modules, and we intend to replicate our past successes in our future endeavors as we backward integrate all the way to producing metallurgical grade silicon from quartz,” said Dr Puneet Gupta, CTO, Adani Solar, “Our Chairman’s vision is ambitious, and we are fully committed to achieving accelerated growth in this business by establishing a fully integrated and comprehensive ecosystem of 10 GW solar PV manufacturing–an ecosystem that not only is vertically integrated but also hosts all ancillary units in the same geography.”

Adani Solar established India’s first GW-scale silicon-based cell and module factory that started production in 2016. It ramped up its annual production capacity of solar PV cells and modules from 1.2 GW in 2017 to 4 GW in 2022, to become the nation’s largest vertically integrated PV manufacturer.
