CaliSolar will construct a polysilicon manufacturing plant in Mississippi, US, at an estimated cost of $600m.

The plant will produce about 16,000t of polysilicon a year, which will be used for solar cells.

The US State of Mississippi has approved $75m in incentives, a $59.5m loan for equipment and buildings, an $11.25m grant and $4.5m for workforce training, reports Bloomberg.

The company says its manufacturing process is less costly than other polysilicon providers as it uses feed stocks that cost a fraction of the conventional raw silicon used by other manufacturers.
