Comparative Study between CSP and CPV as Two Energy Systems

The need to cancel the total dependence of fossil fuels, several researches are established in order to meet this goal, mostly on solar systems. Today, global warming and green energy are important topics of discussion for every intellectual gathering all over the world. The only sustainable solution to these problems is the use of solar energy. The aim of this paper is the dynamic study of a PV system under the solar concentration based on multi-junction semiconductor materials and Fresnel lens associated with a passive heat recovery system, and a CSP technology based on Linear Fresnel Reflectors (LFR) with direct steam generation (DSG) in order to apply them in the region of Adrar where DNI is very important; the system LFR with DSG is dedicated to perform with high temperatures which is produce more power, but high temperatures causes a decrease in CPV system performance; the thermo - electric models and SAM software are used in order to describe and predict their behavior and compare their costs of construction.
