“…It was observed that daytime productivity of still was decreased with the increased mass of PCM but the overall productivity was increased. Tabrizi and Sharak (2010) experimentally studied the performance of basin solar still integrated with sandy heat reservoir. With the use of heat reservoir, overnight productivity of the still was increased and hence the total yield.…”

“…However, for more improvement in distillate output the inclination of condensing cover could have been taken equal to the latitude angle (i.e., optimum angle) of the place. Tabrizi et al (2010) investigated the performance of weir type cascade solar still with and without PCM. Effect of flow rate on system performance was also studied experimentally.…”

“…It was concluded from numerical computation that the maximum yield of solar stills was obtained with lower water depth and by placing the condensing cover to the latitude of the place. Tiwari and Tiwari (2005) (Tabrizi et al 2010) heat and mass transfer coefficients for different condensing cover inclination of the solar still in indoor conditions. Glass cover inclination of 30° resulted in higher yield and high value of heat transfer coefficients.…”

The simplest and easily accessible type of solar distillation is passive solar still which utilizes freely and abundantly available sun energy for removal of salinity/impurity from saline/brackish water. The main drawback of passive solar still is its lower efficiency and distillation output. Different designs of passive solar stills are fabricated and tested by various researchers to meet water demand economically. Concave wick basin pyramidal-shaped solar still was observed to produce 4.0 l/m 2 /day average distillate with a cost of 0.065$/l. Double basin solar still showed an average of 85 % higher yield than single basin still. Stepped type, inclined, tubular, pyramidal, spherical, and hemispherical shapes were considered an efficient designs of passive solar still. Numbers of parameters such as water depth, solar radiation, ambient conditions, condensing cover material, its cooling and direction, internal and external reflectors, sun tracking system, wicks, thermal and energy storage materials were outlined which highly affect the performance of solar still. Water depth of 0.04 m and condensing cover inclination to latitude of the place were observed optimum operational parameters. A distillate output of 4.3 l/m 2 was collected with cotton gauge top cover cooling to V-type solar still. Increase of 75 % in productivity and 56 % in daily efficiency was observed with internal reflector stepped solar still. An improvement of 380 % was observed in stepwise basin solar still integrated with sun tracking system. Despite large efforts carried out on passive solar distillation, there are some challenges like bulkiness, high initial cost, and optimization of spacing between condensing cover and water surface of inclined still, thermophysical properties of basin material, flow rate, insulation material and its thickness, which need to be improved to make this technique efficient in practical utilization. This review paper mainly presents the results of previous work carried out on the designs, operational and process parameters affecting distillation, cost analysis, further scope of improvement in preceding work along with their limitations. The decade reviews on solar stills based on different context authored by many researchers have also been summarized. Moreover, this review paper will help the researchers to understand the basics of solar still with the need, developments and challenges in passive solar distillation to improve its thermal performance.

“…Accordingly, numerous studies have been carried out to store the energy during sunshine hours with higher solar incidence for use at sunset times. One way to improve the storage of solar energy is use of materials with a high heat capacity, which has been studied by some researchers such as Farshchi and Zolfaghari [16], Shanmugan et al [17], Rajaseenivasan et al [18], and Gugulothu et al [19].…”

Abstract:In this study, a thermal model for estimating the efficiency of a basin solar still with an external reflector was introduced using the energy balance equations of different parts of the solar still. Then, in order to verify the precision and accuracy of this model, a basin solar still with an external reflector was constructed and some experiments were performed. The hourly temperature values for different places of the still and amount of distilled water were calculated using the thermal model and compared with experimental measurements. Comparisons show that the thermal model of the still is in good agreement with the experimental results. Therefore, it can be concluded that the introduced thermal model can be used reliably to estimate the amount of distilled water and efficiency of the basin solar still with an external reflector. Results also revealed that the efficiency of the solar still is low in the early hours, while it was enhanced 44% in the afternoon. Furthermore, it was concluded that the accumulated distilled water is 4600 mL/day and 4300 mL/day for theoretical and experimental examinations, respectively.
