The current work presents an experimental study on the distilled water yield in a single slope solar still with varying glass cover angle and basin water depths. The experiments were carried out with different cover angles (25 degrees, 30 degrees, 35 degrees, and 40 degrees) and various depths of water (1, 2, and 3 cm). In addition to the experimental measurements, a numerical model was developed to analyze the effect of different depths of water and various inclination angles of glass cover on the distilled water yield. The numerical results were then validated by the experimental measurements. The shallower the layer of water in the basin the higher the daily productivity. The production of distilled water dropped with an increase in slope of the cover beyond 35 degrees, highest productivity being for the cover slope of 35 degrees.
