The single slope solar still productivity strongly depends on the amount of energy absorbed by the solar still basin plate. Therefore, increasing either the basin plate’s absorption or enhancing the heat transfer with raw water will increase the pure water production rates. To improve the evaporation and the solar still thermal performance, custom-designed evacuated copper pipes with different diameters and water filling rates are experimentally investigated in this paper. Moreover, it has been noticed that pure water productivity is significantly affected as it improved by 90.09% when using a 15mm diameter pipe with a 50% filling ratio.
