Abstract

This paper presents the conclusions derived from the comparative analysis of some representative correlations that are proposed in the literature for the modelling of the Sun-Earth angles. On the basis of these conclusions, we established an improved modelling variant, whose correlations will be used in the design of the solar collectors’ trackers.
