A solar irradiation distribution concept has been used to study the diurnal productivity of a solar still. In this study, a simple single-slope solar still was designed, constructed and tested outdoors (for 9h starting from 4.5h before solar noon each day) at the Malawi Polytechnic ((15o 48′S, 35o 02′E). Meteorological conditions were monitored during the distillation process. In addition, the distillate yield for 32 test days was experimentally and numerically investigated. It was found that the still produced up to 3.454 kg m-2 within 9h of operation, and 4.820 kg m*-2 day*-1 under favorable weather conditions. The mean bias error (MBE) of the models for predicting distillate production improved by up to 57% when the distribution pattern of solar irradiation was incorporated into the equations for numerical computation.
