Optimal static and quasi-static concentrators with a planar receiver for photovoltaic applications are analyzed. Concentrators usually referred to as 'ideal' are shown not to be optimal when material needs, optical efficiency, and collectible energy are considered. Optimal concentrators are obtained by suitable truncation of ideal ones in order to achieve a compromise among the three mentioned aspects. Optimal truncation for all static concentrators (C less than equivalent to 2) corresponds to half acceptance angle theta //A equals 30 degree . If quasi-static concentrators are considered (2 less than equivalent to C less than equivalent to 5), optimal configurations can be obtained from the expressions presented here depending on location and economics.
