Parabolic dish solar concentrators (PDSC) are a CSP system composed of a reflective surface shaped as a paraboloid of revolution (i.e., a parabolic dish), a support structure, a receiver and a sun-tracking system. The entire sun irradiation that impacts the parabolic dish is reflected towards its focus, where the receiver is placed.
