Abstract: A method is presented to calculate the proportions of solar radiation absorbed, reflected and transmitted through sunlit glass which is internally shaded by vertical slats. This method takes into account the variation in latitude of the site, day of the year, time of day, slat orientation angle, width-to-spacing-distance ratio of the slats, absorption of solar radiation and the nature of reflection (diffuse or specular) on the surface of the slats, and the glass thickness. The method consists of following the trajectory of incident solar radiation and considering the multiple reflections which take place between adjacent slats and between the slats and the glass together. We present some results of a simulation obtained for two typical days representing the winter and summer. We conclude that the orientation angle of the slats and their solar radiation absorption play a considerable role in the system performance calculation.
