Abstract: The determination of optimum slope angles for solar collectors plays a significant role in the efficient utilization of solar energy. Monthly, seasonally and yearly slope and optimum slope angles for five locations, Tripoli, Shahat, Hun, Kufra and Ghat where determined using measured data of monthly mean daily global solar radiation on a horizontal surface. Over a period of 7 years, it was found that the annual optimum slope angle is approximately equal to the location latitude, φ while for the winter season it is φ+18 for the coastal cities and φ+21 for cities in the desert and for sumer season it is φ–23 for cosatal cities and φ–19 for desert cities, respectively.
