In this work, performance of a single basin double slope solar still has been studied theoretically and experimentally. The theoretical model is used to predict the year round performance of the still at the local climatic conditions for the year 2008. Average values of maximum and minimum atmospheric temperatures, wind velocities were taken from meteorological data for last five years. Radiation models were used to predict the global and diffused irradiances on the inclined covers. The time to time variations in transmittance of the cover were considered. The rate of production variation and the total production for first day of the every month had been calculated. The overall production of the still was higher during March, April, August, November, and December and it is around 4 L/day. The average production of the still was 2.1 L/day/m2. The economy of the still was also studied and the payback period of the still was three years.
