Desalination of seawater and brackish water is an issue of concern of many researchers in today’s scenario. Solar energy is realizable, simple, profitable choice for water distillation. The present experimental study shows the effect of different operating parameters (water depth, solar radiation, energy storage materials) on a single slope plane solar still. An improvement of distillate output of solar still has been recorded using energy storage material. A comparison between the modified still and conventional still was carried out under the same climate conditions with 5 cm depth of water. The effect of sensible heat storage material have been investigated. The average distilled water production achieved was 2065 ml/m2/day.

Keywords: Desalination, Solar energy, Distillate, Single slope solar still, Sensible energy storage material
