Concentrating solar thermal systems are still little known in Germany, although they are a highly efficient approach to producing heat from solar energy. In such a system, specialised mirrors arranged in different geometries are used to focus the Sun’s rays on a defined area, such as a circle or a line. This heats a heat transfer medium, which then flows through a heat exchanger.
