Abstract

A pyramidal solar still (PSS) and a single basin solar still (SBSS) having been built of transparent glass with a thickness (4 mm) and have the same dimensions of absorber plate which contains the Saline water, and have been constructed under different atmospheric circumstances of Basra city ( Iraq). An experimental investigation was carried out on two solar stills under the same conditions. The still has consists from the basin total area of 0.25 m2. We found in this experimental study that the efficiency of the single basin solar still (SBSS) is (55%) and increases to (66.5 %) of the pyramidal solar still (PSS).
