Enhancing CSP using Spot Fresnel Lens and SiC Coating

Concentrated Solar Power (CSP) systems have a good potential as a renewable energy candidate that are based on converting the incident solar thermal energy to an electrical energy. In this paper, CSP using spot Fresnel lens instead of traditional lenses is presented to enhance the efficiency of the system, where Silicon Carbide (SiC) is used as a coating material for the receiver of the system due to its high thermal conductivity. The presented prototype has been investigated for uncoated spot Fresnel lens CSP, and for spot Fresnel lens CSP with the SiC as a coating material showing the enhancement of the presented design. The experimental efficiency of this design shows a significant improvement in the CSP efficiency. © 2020 IEEE.
