The HelioFocus Dish is a solar concentrator with 219 mirror facets arranged in a Fresnel-like array. The steel structure is based on a stiff torque box with seven extended cantilever arms. The Mirror consists of bent glass with five point supports. A turn table out of steel hollow box girders and concrete ballast weight is supported on four double wheels and a circular crane rail. The azimuth (vertical axis) and elevation (horizontal axis) is driven by hydraulics.
Two different types of receivers were used. First a power conversion unit for generation of hot air (1000 °C) resp. steam via heat exchanger was installed. This unit can be replaced with a micro gas turbine at a later on.
Steel- and concrete construction including the drive technology were developed by schlaich bergermann und partner. The receiver development was done by HelioFocus.
