The department operates the large facilities of DLR’s Solar Research. It provides services both to industry and research partners as well as to customers from other DLR institutes. The high flux solar furnace and the high flux solar simulator of the Institute of Solar Research are situated at DLR's main location Koeln-Porz. These facilities can deliver highly concentrated optical radiation at irradiances up to several MW/m² and radiant powers above 10 kW. Additionally the department has the access to a research platform which has been installed at the half level of the tower of the solar thermal demonstration power tower at Juelich; it is designed to receive radiant power of up to 1 MW.
Besides the provision of highly concentrated optical radiation the department delivers customer consulting services to design experiments and special test arrangements, to carry out and to supervise experimental campaigns, to acquire and supply experimental and related meteorological data, as well as to support the evaluations. In addition to the services the department comprises research on materials employed in solar electricity, process heat and fuel generation.
