Solar parabolocilindrical installations, constructive features and calculation of individual parameters

The article gives a brief description of a solar parabolic-cylindrical installation and its main element, an optical concentrator. The analysis is based on the most simplified and sufficiently accurate methodology for calculating the coefficient of geometric concentration of parabolic-cylindrical mirrors. The cases of an ideal parabolic-cylindrical concentrator having a small aperture are considered. A variant of calculating the concentration coefficient of a parabolic cylindrical concentrator for cylindrical and flat receivers is presented.
