More often than not, the study of solar stills and their performance is restricted to the solar radiation at the place of study, certain parameters and factors have been found to improve the performance of solar stills in terms of efficiency. We investigated some of these factors namely: wind speed (v) and wind direction, angle of inclination (β), of the cover, ambient temperature (Ta) of the surrounding air, temperature (Tw) of the water, and the internal cover (Tc) temperature as well as the solar radiation and found out that their variations affect the efficiency of a single basin solar still considerably.
