“…Energy efficiency is considered as one of the most important criteria used to assess the performance of SSs [32] The total efficiency,  , is obtained by the summation of the hourly yield ew m multiplied by the evaporation latent heat fg h divided by the diurnal average insolation The balance equations of exergy for the three main components (basin-liner, saline water and glazier cover) of the SS are given in our previous work [32] . Assuming that the heat capacity of the components materials is negligible, and hence the accumulation of exergy could be neglected.…”

“…Exergy is a strong instrument to identify the causes, locations and magnitude of the system inefficiencies. In addition, it provides a precision measure how the SS approaches to the ideal [31,32]. It was found that for all renewable conversion energy systems, the evaluation according to exergy analysis was establish to be less significant than that of the energy analysis [32].…”

A novel experimental approach is presented where studies have been conducted on a solar still at four specific heights in the range of 0.266–0.341 m (in steps of 0.025 m) keeping other dimensions constant. Performance of solar still is established under indoor environment to suppress meteorological factors. Uniform heat was supplied to the solar still through flat plate‐type electrical heaters. For each specific height, the performance of the solar still was evaluated at five heat fluxes (600–1000 W/m2 in steps of 100 W). Performance of solar still at different specific heights was compared in terms of operating temperatures, productivity, and efficiency. It was found that reduction in specific height enhances distillate productivity as well as thermal efficiency of the solar still due to reduction in cavity volume and an increase in average operating temperature. An increase of in daily distillate yield of 89.44% (at 600 W/m2), 56.07% (at 700 W/m2), 28.50% (at 800 W/m2), 38.60% (at 900 W/m2), and 37.38% (at 1000 W/m2) between Case 1 to Case 4 was observed. Further, between Case 1 and Case 4, the thermal efficiency increased from 27.29 to 46.18%, 32.73 to 51.06%, 36.82 to 52.17%, 41.25 to 56.79%, and 42.55 to 57.50% at 600, 700, 800, 900, and 1000 W, respectively. Results demonstrate that for a particular specific height the total daily productivity increases linearly with heat flux. Correlation for estimating thermal efficiency of solar still is proposed in terms of the aspect ratio and input power. © 2019 American Institute of Chemical Engineers Environ Prog, 38: e13227, 2019

“…Average distillate output reported for solar still with the effective area of 0.25 m 2 is 2.01 l/m 2 and 1.88 l/m 2 at water depths 4 cm and 6 cm respectively (Himanshu and Mahesh, 2017). The literature survey briefly references that the research on the solar distillation system is highly persuaded towards the passive solar stills (Sharshir et al, 2017;Shashikanth et al, 2015). Based on the observations made and research gaps identified during the literature survey, the presented experimental research was directed to following:  to apply Taguchi method for design of experiments by selection of set parameters for solar distillation and collect data about the effect of different energy storage materials on the performance of single slope still,  to find and test best set of parameters like water quantity, type and quantity of energy storage materials with purpose to enhance solar still output,  to create description of solar distillation productivity depending on energy storage materials parameters,  to evaluate relative significance of the process control parameters and their contribution in the distilled output,  to estimate the quality of still process by of TDS (total dissolved solids) measurement for brine and distillate.…”

Solar distillation is one of the important methods of getting clean water from brackish and seawater using the renewable energy of the sun. The passive type solar still represent most economical method to supply drinking water for domestic applications for decentralized level. Experimental measurements of solar distillation productivity for single slope still were conducted at the testing field of the Mechanical Engineering department, Coimbatore Institute of Engineering and Technology, Coimbatore, Tamilnadu, India. The influence of basin water quantity and amount of energy storage materials are examined and the performance is compared. The target of this research is to find best way to keep the excess heat by energy storage materials and release it during off-sunshine hours for increment in distillate output and efficiency. Various sensible heat energy storage materials like pebbles, blue metal stone, red brick, granites and white marbles were used as energy storage medium. The daily yield of black granite still is higher than other energy storage material stills and is equal to 3.216 kg/day/m 2 , which is 29% higher than that of the still without energy storage materials.
