Concentrix Solar builds large concentrator solar power plants suitable for sunny areas.[2] In 2007, Concentrix Solar was awarded the Innovation Award of the German Economy for its CPV technology.[3] From February 2006 to December 2009, the investment company Good Energies was invested in Concentrix Solar.[4] Abengoa Solar was an investor of Concentrix Solar from November 2007 to December 2009.[5]

Technical details[edit]

Concentrix concentrated photovoltaics(CPV) modules bundle sunlight up to 500 times with the use of fresnel lenses and focus it on III-V based Triple-junction solar cells (GaInP/GaInAs/Ge),[6] which then convert the light into electrical energy.[7] To ensure that the sunlight is concentrated precisely on the solar cell the CPV modules are installed on a two-axis sun tracking system.[8] With its CPV technology Concentrix Solar achieves a module efficiency of 27%.[9]
