Qatar Foundation (QF) subsidiary Qatar Solar Technologies (QSTec) has increased its investment in the SolarWorld group, with the purchase of 49% of the equity in SolarWorld Industries GmbH, a special purpose vehicle bundling up the troubled German renewables company’s assets. In late August, insolvency administrator Horst Piepenburg sanctioned the sale of nearly all property, plant, equipment, inventories and intangible assets of four SolarWorld companies, which were bundled into the newly-created SolarWorld Industries. It includes production plants in Freiberg and Arnstadt in eastern Germany.
