“…In some cases researchers uses specific geometry for solar still such as double-slope [ 28 , 29 ], tubular [ 30 , 31 ], pyramid [ 32 , 33 ], hemispherical [ 34 , 35 ], spherical [ 36 , 37 ], stepped [ 38 , 39 ], and asymmetrical [ 40 , 41 ] to make an improvement on system. The most prominent passive techniques can be mentioned such as using energy absorbing/storing materials (sands, cement, and marble pieces) [ [42] , [43] , [44] ], porous media [ 45 , 46 ], utilizing phase change materials (PCMs) [ [47] , [48] , [49] , [50] ], using wicks [ [51] , [52] , [53] ], fins [ 54 , 55 ], internal/external reflectors [ [56] , [57] , [58] ], film cooling [ [59] , [60] , [61] ], increase the rate of heat and mass transfer by utilizing different nanoparticles in absorber/fluid/cover of solar stills [ [62] , [63] , [64] , [65] , [66] , [67] , [68] , [69] , [70] ]. Meanwhile, integration with humidification-dehumidification systems [ 71 , 72 ], thermoelectric modules (for heating and cooling) [ 73 , 74 ], and external/internal condensers [ 75 , 76 ] are another modifications for enhancing the performance of system.…”

“…Panchal et al. [26] conducted theoretical and experimental studies on solar stills with marble pieces and sandstones as heat energy storage materials; moreover, they investigated the effect of cooling and dripping arrangements on these stills. It was found that compared to that of conventional still, the distillate output values of solar still with sandstones and marbles increased by 30% and 14%, respectively.…”

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.

“…They have also reported the overall efficiency of MSS is 44.64% higher than CSS. Panchal et al [9,10] have reported fins to increase productivity due to an increase in surface area of water at the basin. Fins have also reduced the bottom and side losses in CSS.…”

Experimental evaluation of conventional solar still (CSS) and CSS with sand-filled glass bottles (Modified solar still (MSS)) have been reported in this article. Two identical CSS were fabricated for the experiments. The experiments were designed and performed under Guna (India) weather conditions in November 2021. Sand-filled glass bottles were paced as sensible energy-storing material. The mathematical model proposed by Kumar and Tiwari has been utilized to evaluate internal heat transfers, internal efficiency, and exergy efficiency. For checking the economic feasibility of sand-filled glass bottle within CSS, a comparative cost analysis has been performed to evaluate CPL (Cost per Litre). It has been observed that the MSS has yielded 21.32% more than CSS. And overall internal efficiency has also increased by 139.45% due to the presence of sand-filled glass bottles.
