Analysis of Solar Distillation System for Clean Water Distribution : A Review

Abstract

Different solar stills technologies is widely reviewed to digest their pros and cons. Solar still is a natural phenomenon of purifying sea and brackish water to provide affordable and reliable potable water. For the technology to be sustainable and utilized on a large scale, productivity needs to be improved. The factors that contribute to the performance of a still were highlighted and analyzed. And the energy and mass balance that takes place in solar still was expressed and defined by different researchers. The efficiency of a still is determined by the temperature variation of the evaporated water in the basin and the outside temperature of the glass cover. The insulation material plays a vital role in the prevention of heat loss and conservation of heat energy to increase the overnight yield when solar energy is not available.
