 Optimum slope of a north-south aligned absorber plate from the north to the south polesN. Nijegorodov and P.K. Jain Renewable Energy, 1997, vol. 11, issue 1, 107-118 Abstract: The analytical method developed by Nijegorodov et al. [Renewable Energy, 4, 529–543 (1994)] in order to find the optimum slope of an absorber plate, variously oriented at any latitude, is applied to study the variation of daily optimum slope with latitude from the north to the south poles. For a clear, cloudless condition the daily optimum slopes are found to have symmetry features which reflect the symmetry of the motion of the sun and the north-south symmetry about the equator. Such symmetry features of the optimum slope are discussed. However, the actual optimum slope also depends on the local meteorological and sunshine conditions, due to which the symmetry features of optimum slope are not always exploitable. The effects of meteorological parameters such as temperature, pressure, relative humidity, visibility and cloud cover on the optimum slope are assessed. The method is applied to obtain the mean monthly optimum slopes for the locations of 12 synoptic stations in Botswana from which the climatic and sunshine data are available, and preliminary maps of mean monthly optimum slopes for Botswana for the months of June and December are presented.
