In this paper, a short introduction in design considerations of FLATCON® CPV module and field data of the system technology over up to two years are presented as well as field experiences with the operation of the systems. FLATCON® modules are based on III–V triple junction cells, a Fresnel lens array, and a glass cover and bottom plate. In 2008, Concentrix installed a single tracker system and two power plants in Spain. A system solar‐to‐grid AC energy efficiency of 21% over the whole period of two years with maximum system AC power efficiency values of 23% for a single tracker system are shown. Similar systems installed in 2009 and equipped with the current FLATCON® module CX‐75 achieved system AC power efficiencies of 25%. The effects on power plant performance of spectral variations of the solar irradiation, soiling and also dew formation in wintertime are discussed.
