The investigated concentrator labelled as P2CC has a tubular receiver and two identical reflectors, one from each side of the tubular receiver. The tubular receiver is a concentric tube consisting of a metal tube (absorber) inside the glass tube. Each reflector curve is defined by using three curves where one curve is parabola and two curves are circular arcs. The prototype P2CC has high efficiency, low price, possibility of its production in small and medium companies, and wide distribution. Its application in a large part of year (or entire year) would mean significant savings of electric energy which is now used for preparation of warm water, and in central and long-distance heating systems.

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.
