SunEdison says it will jointly fund a feasibility study regarding the factory with the Saudi Arabian Investment Company (Sanabil Investments) and the country’s Public Investment Fund, with an eye towards beginning production by 2017.

The polysilicon-through-module factory, to be sited at a planned industrial complex in northern Saudi Arabia, is expected to cost $6.4bn. There are few such vertically integrated PV factories in the world, and none on such an ambitious scale.
