WebApr 1, 2024 · In solar thermal power plant, operating with cylindrical parabolic collectors, the solar field is considered to be the most important part which contains mirrors intended to intercept the solar radiation and to concentrate it in a focal point [ 1 ]. WebA parabolic mirror produces an image of the sun on the surface of the receiver, so the receiver size needs to be matched to the image size. Consider Figure 2.10, which illustrates this idea. Since the sun is not really a point source, solar beam incident on the reflector is represented as a cone with an angular width 0.53 o (so the half-angle ...
