The effect of the tilt angles of the single-tilt and single-basin solar still on productivity and efficiency

Abstract

Researchers are turning to renewable energy sources as a viable solution to the worldwide water deficit and fossil fuel pollution.  Solar stills simulate evaporation and condensation in rains. This process removes pollutants, organic and inorganic chemicals, and bacteria from the basin without transport by the vapour, producing high-quality water.

 The single-basin, single-tilt solar still was created and implemented in this research. The practical part involved monitoring the amount of distilled water generated at three tilt angles (22°, 28°, 34°) during a month in Tikrit, located at (34.6°N, 43.68°E). We also used experimental data to create a model that relates water production to solar radiation, maximum ambient temperature, and wind speed.  The highest yield of 4.5 litres per day and 45% operational efficiency was achieved at 28° tilt angle.  Local manufacturing at low cost made the gadget economically viable.
