Abstract: The theoretical physical conditions tor the production of heat at temperatures in the range of 8oo $^\circ$C - 1ooo $^\circ$C with solar energy are presented and a small experimental facility with an output power of 3oo - 4oo watt for Investigating these conditions described. Energy storage, which is of special importance for the application of solar energy, is possible in the high temperature range by utilizing the enthalpie of reversible thermochemical processes. As an example of the principle, the operation of a small solar power station using the SO$_{3}$-process for energy storage is explained. A high thermal efficiency of the solar concentrator-absorbersystem, which should theoretically approach 80 % is reached with concentration rates of about 1ooo. lt is possible to use industrially produced unpolished reflectors (parabolic mirrors) as concentrators. In the experimental patt, the experlenees with this concentrator-absorber system with regard to the equatorial mounting, suntracking and high-temperature-cavity absorber, which is made as calorimter for the measuring, are reported. The first results are presented for measurements made at the desired temperature level for several parabolic concentrators of different sizes and constructed fror different materials. These results inelude theoutput power at the temperature level, the collector-absorber effiency and the relative energy distribution in the focal plane, which was measured by a specially developed foil radiometer.
