The Institute of Solar Research develops concentrating solar systems for the generation of heat, power and fuel. These technologies are used, for example, in Solar power plant in Spain, the United States and many other countries with high levels of direct solar radiation. The Institute is represented at the DLR sites in Cologne, Jülich and Stuttgart. In southern Spain, scientists from the Institute are conducting research at the Plataforma Solar de Almería (owned and operated by Spanish research centre CIEMAT), Europe's largest research facility for concentrating solar systems.
Jülich is home to the Institute's two large-scale facilities: Germany's only solar tower and Synlight, the world's largest facility for the production of artificial sunlight. In addition, the Institute operates a solar furnace at its headquarters in Cologne and a small high-flux solar simulator.
