Abstract

A ray-optical evaluation of the constructional and concentration characteristics of a composite parabolic trough (CPT) with flat receiver is given. The region of non-zero intensity in the focal plane, the intensity in the central solar image and the receiver intercept fraction for a typical CPT are studied and the significance of the results at the design stage is pointed out.
