    Distillation is one of the effective techniques used to purify the water. Solar still is a device which distills water using solar energy. In this study an attempt is made to investigate the effect of phase change materials on the productivity and performance of single slope solar still. A single slope wooden solar still, having base area 0.2679 m² and inclination angle of glass 30°, is used. Paraffin wax and Sodium sulphate Decca hydrate, encapsulated in circular aluminum tubes, were used as phase change materials (PCM). Experimentations were carried out by using both types of PCM and without using Phase Change material. A comprehensive comparison is made to examine the effect of phase change material on productivity and efficiency of solar still. The productivity values observed for the cases of without PCM, with paraffin wax and with sodium sulphate were 1.92 L/m² per day, 2.27 L/m² per day and 1.99 L/m² per day respectively. Results shows that the productivity of solar still is maximum for the case of paraffin wax under similar conditions. Also the maximum efficiency of solar still is observed when paraffin wax is used as energy storage medium.
