In order to augment the efficiency and distillate yield in the concentrator-coupled hemispherical basin solar still, a phase change material (PCM) was added. Two modes of operation have been studied experimentally, (1) single-slope solar still without the PCM effect, and (2) single-slope solar still with the PCM effect. The temperature of water (T_w), temperature of PCM (T_PCM), air temperature (T_air), inner cover temperature (T_ic) and outer cover temperature (T_oc) were measured. Experimental results indicate that the effect of thermal storage in the concentrator-coupled hemispherical basin solar still increases the productivity by 26 % . It was concluded that the productivity greatly increased due to the still integrated with PCM.
