Abdelkader Bellila. Evaluating the Impact of Absorber Geometry on Solar Still Efficiency: A Comparative Study of Square and Round Absorbers

Abstract

Solar stills have been used for many years in areas with limited access to fresh water, such as desert regions or remote locations. They are simple to construct using readily available materials and require no energy input other than sunlight. Additionally, solar stills are lowmaintenance and can produce a significant amount of pure water with relatively little effort. Two solar stills are exposed to the sun, the first is a single solar still and the other is a hemispherical sender. Both stills have similar absorber. The purpose of this experiment is to compare the pure water output of the two devices. The finding shows that hemispherical solar still is more efficient than the simple solar still by 54.30 % in terms of pure water output. This suggests that the hemispherical still is better at capturing and utilizing solar energy to evaporate and condense water.
