“…Solar stills can be classified into active and passive solar stills. Many papers have studied more specific characteristics of solar stills with various configurations, hemispherical solar stills [4], spherical solar still [5], pyramidal solar still [6], double-basin solar still [7][8][9][10][11], vacuum solar still [12], compound parabolic concentrator (CPC) solar still [5], wick type solar still [13], triple basin solar still [14], multiple basin solar still [15,16], inverted absorber solar still [17][18][19][20], tubular solar stills [20][21][22][23], solar still coupled with solar collectors, and thermal storage [24][25][26][27][28][29][30][31].…”

This study presents a theoretical model to simulate the temperatures and productivity of a single-slope, single-basin solar still when an external solar enhancement is used. Experiments were performed in the New Mexico region (32.3199° N, 106.7637° W) to validate the numerical model. A point focusing Fresnel lens was used in the experiments to enhance the solar input. It was found that a significant rise in the productivity of the still was achieved with the Fresnel lens. Parametric study by varying the water depth showed the Fresnel lens was more effective for larger water depths. In addition, the Fresnel lens can aid in improving the overall efficiency of the solar still.

This paper is aimed to investigate the heat transfer behaviours of a single slope solar still under the tropical climate at Kota Kinabalu city, Malaysia. Both theoretical and experimental approaches has been performed and discussed. The theoretical heat transfer principal behaviour of the single slope solar still is successfully modelled based on the heat exchange processes of three major components of the solar still (glass cover, seawater and basin) and its surroundings. The theoretical model developed has shown to predict closely the experimental trend of the heat transfer processes of the solar still system. Outdoor experiment is also carried out under the Kota Kinabalu, Sabah, climate that showed a maximum output of 1.4 litres per day of clean distilled water and has achieved a high and consistent system temperature of 80.0°C. In comparison with the theoretical and the experimental results, the theoretical model is found to closely predict the solar still behaviours at the early hours in the morning where the solar irradiance is intense and consistent.
