As concentrated solar collectors can focus only on direct solar radiation, their performance is poor during cloudy days. The cost of building and maintaining concentrated solar collectors is high. Concentrated solar collectors are practical for implementation only in areas with high direct insolation, such as arid and desert regions. The Way

Focusing solar collector systems can be seen as optical systems consisting of a light source (moving sun), concentrator, and receiver. As shown in Fig. 2.41, the concentrator concentrates solar radiation on an unthreaded hole to a focal plane on the receiver through refraction and reflection.The medium on the receiver removes heat converted from solar energy.
In this chapter, we tried to categorize the concentrating solar collectors through their focusing shape which can be line focusing and point focusing. Moreover, some ways to improve the efficiencies of these devices are presented. In the end, the importance of using these collectors, their provided clean energy throughout the world, and
Non-Focusing or non-concentrating Type Solar Collector • In the non-concentrating type, the collector area (i.e. the area that intercepts the solar radiation) is the same as the absorber area (i.e., the area absorbing the radiation). • In this type, the whole solar panel absorbs the incident light.

There is a pipe in the centre of this trough that functions as a carrier of water. The sunlight gathered by the reflective material is focused onto this central
other solar collector field row. The optical performance of the solar collector field is affected by following parameters (Sharma et al. 2015a): • Latitude of the place. • Day and time. • Length and width of the concentrating solar collector. • Spacing between two adjacent solar collector rows. • Orientation of the solar collector
For non-focusing type collector i.e. flat and evacuated tube collector, its value is 1 while for parabolic trough (line focusing), its value can be up to 100. For point focusing (dish collector), its value can be considered up to 1000. The concentration ratio of the collector is given by following relation [16, 24].
