Elkem Solar has resumed production of solar grade silicon at its plant located in Kristiansand, Norway.

During the temporarily halt of the production at the plant, the company had carried out improvement projects to increase the value of its products and reduce costs.

The Kristiansand plant will soon operate at its full production capacity, said the the company.

Elkem Solar CEO Inge Grubben-Strømnes said the solar industry has been going through a challenging period with overcapacity that forced the company to temporarily halt production.

"However, strong underlying demand growth and recent price increases enables Elkem Solar to restart production. We are currently experiencing increasing prices and demand for Elkem Solar Silicon," Grubben-Strømnes added.

Elkem Solar sales and marketing vice president Torgeir Ulset said independent tests were carried out in India and Australia that have revealed 2.5% higher electricity production than modules produced with standard Polysilicon.

"This effect is caused by improved temperature coefficient and through the electrical properties and composition of trace elements in ESS," Ulset added.
