Determination of the dimensions of parabolic-cylindrical concentrators and the amount of energy incident on the reflective surface

This paper examines the geometric dimensions of parabolic-cylindrical concentrators and determines the amount of solar energy incident on their reflective surfaces. The study considers the main parameters of the concentrator, including aperture width, focal length, depth, length, and reflective surface area. The amount of solar energy reaching the reflective surface is determined according to the intensity of solar radiation, the effective collecting area, and the angle of incidence. The relationship between the geometric characteristics of the concentrator and the amount of collected solar energy is also analyzed. Proper selection of the concentrator dimensions can improve the concentration of solar radiation and increase the efficiency of energy collection. The results of the study can be used in the design, calculation, and optimization of parabolic-cylindrical solar concentrators and solar thermal energy systems.
