| Abstract: | In this paper, the temporal and spatial variations of the optimal tilt angle for daily total of global radiation in months are analysed based on the insolations on the horizontal surface and albedo measured from fifty-five stations with its analytical expression given before. The main results are found as following:
(1) Annual averaged errors of the optimal tilt angles are less than 1.7 and the mean errors of the global radiation amount on the tilted surfaces at the optimal tilt angles are about 0.4% for the all stations.
(2) The isotimics of the optimal tilt angles are essentially parallel to the latitude circle, however that is not true in the cloudy areas especially in Sichuan, Guizhou and Guangxi provinces, even they take south-north direction. Therefore it is necessary to take account of the effects of clouds on the optimal tilt angles when they are estimated.
(3) The isotropic model is applicable for estimating the total of global radiation falling on the surfaces tilted towards the equator. |
