Sudan is one of the largest countries m the African continent situated between latitudes of 3° N and 23° N and longitudes 21° 45 E and 39° E. The total daily sunshine hour is between 8 to II hours, and the average solar radiation received on the horizontal surface is between 20 to 24 MJm-2 day·1 as a result Sudan has very hot and dry weather. Air cooling is clearly needed in such weather, and the utilization of solar energy for this purpose is very appealing especially that grid supply is not available to several parts of the country, and where it is available it is usually very unstable in hot season. This report presents Hybrid Evaporative cooler powered by Stand-Alone Photovoltaic system. Steps taken to develop this cooler and a comprehensive review of several conventional and solar cooling techniques and the advantages of the new cooler are also presented. The hybrid evaporative cooler was found to have performance criteria suitable for Sudan and low power consumption what makes it economical when powered by Stand-Alone Photovoltaic system. This report also introduces sizing method for stand-alone photovoltaic system to power the cooler and a software tool to perform the sizing procedure. A full system was developed for the city of Khartoum to show the feasibility of the proposed system.
