Abstract: A solar collector 1 for the temporary storage of heat from solar radiation comprising a radiation conductor 8, 9 for conducting the solar radiation, and lens means 7 for concentrating solar radiation onto a first extremity of the radiation conductor. A thermally-insulated core 2 is provided on an opposite second extremity of the radiation conductor 8, 9 in order to be heated by the solar radiation released from the radiation conductor and temporarily storing the heat. For this purpose, the core is provided with an insulated casing 4, virtually completely enveloping the core, which insulated casing 4 comprises a layer of porous ceramic material.

Abstract: A device (1, 20, 40) for collecting solar energy includes collector elements (3) and lens elements (2) for concentrating solar radiation onto the collector elements (3). The collector elements (3) are coupled via a conduit for energy transport to an energy processing unit. The lens elements (2) include at least one lens (2) which is arranged movably. Drive elements are provided to orient the at least one lens (2) about at least one orientation axis. The drive elements are provided with a control for the purpose of orienting the at least one lens (2) in at least substantially continuous and in at least substantially optimal manner relative to an actual position of the sun.
