Four single-effect, basin type solar stills were designed, constructed and tested. Three stills had a glass cover of different thicknesses (3, 5, 6 mm) while the fourth cover was plastic. The still with the thinnest glass cover had shown the highest production rates, up by 15.5%. Empirical equations were obtained to express the dependency of the yield on the ambient temperature and solar radiation. Also, software was prepared to solve the governing equations numerically so that the effects of various parameters on the output could be investigated. For one of the glass covered stills, the measured yield was compared with the prediction.
