Various methods are used for obtaining drinking water from salt water. One of these methods is the distillation of the salt water by solar energy. In this work, the effect of extended surfaces in a solar-still system is investigated experimentally. Two distillers are constructed to use in experimental works. One of these distillers is conventional distiller and used as a reference. The other distiller is used to investigate the effect of extended surfaces. The experiments are carried out in Elaz??/Turkey climate conditions. In the experiments, Climate conditions (Solar radiation, wind speed, environmental temperature), Glass cloth temperature, distiller pool temperature, base temperature, distiller side wall temperature and the amount of distilled water are measured and evaluated. To extend the surfaces, table tennis balls with diameters of 40 mm, which are painted black, are used. To move the balls in the distiller, the salt water is sprayed from sides by a circulating pump. In the experiments, the amounts of distilled water are compared for stationary and moving balls. Obtained results show that extended surfaces improves the efficiency of distillation system.
