The geometrical accuracy of a real solar concentrator is defined quantitatively in terms of two equivalent parameters: the standard target error and the angular error; and the relationships between these parameters and the flux distribution on the focal plane are developed. A general method for determining the optimum size and efficiency of an absorber for any given concentrator is described. Specific numerical results are obtained; however, only for the case where the function describing the flux distribution on the focal plane is given by Gauss’ normal law of error. Criteria for determining the applicability of the results are proposed. Finally, experimental techniques (both optical and thermal) of evaluating concentrators are briefly described.
