Abstract: Liu and Jordan's formulae (Liu and Jordan, 1962) are revised to estimate the global rediation on inclined surfaces with azimuth from-180° to +180° in Shenzhen. The method for determination of the sunrise and sunset hour angles and the sunshine duration on sloping surfaces in low latitudes is discussed. From the data of direct, diffuse and global radiation on the horizontal surface in the city, the values of Rb and R for each month are calculated, where Rb and R are the ratioes of the average direct and global radiation, respectively, on the tilted surfaces to that on a horizontal surface. It is shown that in some periods of the year, the surfaces toward south, southeast and southwest, within a certain slope range, can obtain more global radiation than the horizontal surface. The annual global radiation on a southward slope of 19° reaches a maximum,3.4% more than that on a horizontal. Since Shenzhen is situated south to the Tropic of cancer, in about 15 days before and after the Summer Solstice, the global radiation on a northward inclined surface is more than that on a southward one at same slope. The annual course of global radiation on a tilted surface differs from that on a horizontal and varies with slope and azimuth.
