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.

This study primarily focuses on comparative experimental analysis on standalone conventional solar still (CSS), inclined solar still (ISS), and integrated conventional and inclined solar still (CSS‐ISS) for different parameters that affect the freshwater yield. For enhancing the freshwater yield only a few studies are available on still‐still integration. The present novel study provides a greater improvement in improving the freshwater yield by integrating ISS with CSS. This experimental work mainly concentrates on the importance of water depth (d w) and mass flow rate of water ( m w) in the solar still. Water depth inside the conventional still varied from 0.02 to 0.06 m whereas, water is constantly flown with a mass flow rate of 8.33 kg/hour in an ISS with baffles. The experimental result shows that the accumulated freshwater yield from CSS‐ISS, ISS, and CSS were 6.2, 5.04, and 4.24 kg, respectively. CSS‐ISS and ISS produced 46.23% and 18.87% higher productivity than the CSS. From the experimental investigation, it is also identified that the water temperature is significantly improved by 20% using integration as compared with CSS without integration under the same water depth of d w = 0.02 m. The overall improvement in yield was higher in the case of CSS‐ISS. The deviations between experimental and theoretical values of yield from the conventional and modified solar still were in the range of ±7%.

“…The results showed that, the annual average values of the daily productivity and efficiency of the still with shallow solar pond were found to be higher than those obtained without the solar pond by 52.36% and 43.80%, respectively. Corrugated wick type solar still and simple basin solar still type were manufactured and tested to compare the enhancement of the corrugated wick type still with the simple still by Matrawy, K. et al [12]. An improvement of around 34% was recorded in the productivity for the proposed wick type solar still when compared with the simple basin solar still case.…”

This paper presents an experimental study of performance of water stirring solar still. The Conventional Solar Still (CSS) has been modified, developed and tested to enhance the performance by using water stirring method. This modification was performed by fixing a mechanical wiper on the bottom of still basin. The experimental results on the modified solar still were analyzed and compared with that of conventional solar still (CSS) that has the same basin area, dimensions, water depth and operating conditions. Results showed that, the accumulated productivity from the water stirring solar still (WSSS) ranges from 3.27 to 3.82 L/m 2 per day at water depth of 2 cm. The corresponding values for (CSS) range from 3.0 to 3.5 L/m 2 per day. The increasing in productivity for WSSS is about 9.14 % more than that of the CSS.
