This is a computer code for analysis of point - focus concentrators wuth flat targets. CIRCE, an acronym for convolution of Incident Radiation with Concentrator Errors, was developed for the optical analysis of point-focus concentrating dish collector systems. The solution techniques of CIRCE, in which the concentrator errors are convolvedwith the solar intensity profile (sunshape) to produce the flux density distribution onan arbitrary target, are identical to those used in HELIOS. CIRCE may be used to analyze reflectors that are spherical, parabolic, or flat and are either a continuous or faceted surface. The curvature and aim point of each optical facet that comprises the reflector may be individually assigned. The current version of CIRCE, referred to as CIRCE.OO1, is restricted to analyses of reflector systems with flat rectangular or circular targets.

Abstract
In this chapter, description and working principles of the parabolic trough power plants, solar tower power plants, parabolic dish power plants, and power plants with Fresnel reflectors in the world and their potential use in Serbia are given. In addition, the examples and technical characteristics of some concetrating solar power plants in the world are given. The cases in which solar cells are used to generate electrical energy are very rare. Solar systems referred as mid temperature (100–400 oC) are considered suitable for integration with industrial processes, cooling, and polygeneration systems through use of concentrating solar collectors. The results of this research may be applied in the construction of small solar systems, but also in the design and construction of large polygeneration systems. Physical and mathematical model is presented, as well as numerical procedure for predicting thermal performances of the P2CC (Parabolic-and-Circular Collector) solar concentrator.
