A solar still is used to convert saline water into potable water by means of the distillation process. In order to improve the productivity of conventional solar still, various modifications are implemented by researchers. In the present study, multiple V-shaped floating wicks are used to enhance heat absorption and thereby increase productivity. The experiments are performed during the summer and winter seasons in Rewa, India (Latitude: 24.5373° N; Longitude: 81.3042° E). These multiple floating wicks are made from black jute cloth wrapped in V-shaped pieces of thermocol. Because of their V-shaped profile, the evaporative surface area of modified solar still is 26% larger than that of conventional solar still. The maximum daily productivity in one of the clear days is found to be approximately 6.20 kg/m 2 in summer and 3.23 kg/m 2 in winter with daily efficiencies of 56.62% and 47.75%, respectively. A theoretical thermal model is formulated by using the energy balance equations of the modified solar still. Reasonable agreement was seen between the theoretical and experimental results of modified solar still. An economic analysis is also performed for the modified solar still and conventional solar still; in a 10-year life cycle, the annual cost of distilled water is estimated at Rs. 1.81/kg for the former and Rs. 2.24/kg for the latter.

“…For example, Pakdel et al multiplied the highest system daily yield by the number of operation days to get m water [70]. In contrast, Haddad et al used an averaged system daily yield, which was obtained by considering the test results of different seasons [71]. In the current study, the method in Reference [70] was adopted, because the proposed solar still system was only tested during the summer season.…”

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.

Unlike conventional fresh water producing systems, from saline or brackish water, the innovative solar water producing systems are efficient and effective. Experiments were conducted on two identical roof-type solar stills and simultaneously tested under the same weather conditions. One of these stills was modified by integrating a vacuum pump to lower the pressure inside while the other still was used as a reference unit. Different concentrations of Al 2 O 3 nanoparticles were chosen, 0.2%, 0.4%, and 0.6%, and used with water inside the modified still. It was verified that the modified still, without nanoparticles, yields 34.84% more production than the conventional still. In addition, the modified still with a 0.4% of Al 2 O 3 nanoparticles produced the highest percentage of distilled water, 44.42% in comparison to the one without the use of Al 2 O 3 nanoparticles, followed by 37.94% and 24.07% for 0.6% and 0.2% of Al 2 O 3 nanoparticles, respectively.
