In this work two single slope solar stills have been designed and constructed from Materials available in the local market. One is conventional and the other with a wick surface. This paper deals with the effect of corrugated work by wick surface on the performance of the still. The two stills were tested for three days, where the effects of solar radiation intensity and ambient temperature have been investigated. Saline water temperature in the still with jute cloth is raised to about 82 °C

... ch appreciably reduces the heat losses from the still compared with the conventional still water temperature of about 76 °C. Still daily yield with the jute cloth is 4.20 kg/m2 per day while the conventional solar still is 3.30 Kg/m2 per day. Maximum efficiency of the still with the wick surface is found as 42% while the efficiency of the conventional solar still is 33%.
