A macroscopic approach to the optical analysis of a solar concentrator is described. The method yields all the parameters needed for the optical design of line focus parabolic troughs. The flux at the receiver is determined as a function of concentrator along with receiver size, width of Sun, and optical errors.

Introduction. Paraboloidal dishes have been widely used to concentrate solar radiation and convert it into medium–high temperature heat, including solar cooker (Badran et al., ), solar hydrogen production (Joshi et al.,Furler et al., ), and Dish–Stirling system to harvest electricity (Mancini et al.,Mills, ).In fact, the sun is not a point source of light, and   Optical analysis and optimization of line focus solar collectors: [5] UNE-EN ISO “Geometrical product specifications – Surface texture_ profile method –Terms, definitions and surface texture parametersâ€.
