The objective of the present study is to evaluate the sustainability of solar still by enhancing the condensation rate using natural fibers on the glass cover. It is accomplished by employing naturally available Banana Fibers (BF) and Jute Fibers (JF) over the glass of the solar still (SS). The experimental investigation on Conventional Solar Still (CSS), Solar Still with Banana Fibers (SSBF) and Solar Still with Jute Fibers (SSJF) is conducted under similar meteorological conditions. The results reported that the glass cover temperatures of SSBF and SSJF are significantly reduced by 23% and 28% respectively relative to CSS. Also, the condensation rate in SSJF is comparatively better than SSBF and CSS. The significant factor for improving the condensation rate is the absorption, retention, and porosity of natural fibers. Nevertheless, the potable water yield of CSS, SSBF, and SSJF is noticed as 2.23, 2.87, and 3.18 L/m2, respectively. Besides, the viability of solar stills is assessed by economic analysis and the cost per liter (CPL) of water obtained from SSJF is about $ 0.029 with a payback period (PBP) of 4.7 months whereas SSBF and CSS are having a CPL of $ 0.034 and $ 0.041 with a PBP of 5.6 months and 6.8 months respectively.

“…It was noticed that the integration of hollow fins enhanced the productivity by 43% whereas the productivity of solar still with both fins and energy storage improved the freshwater productivity by 101.5% relative to the productivity of CSS. (Suraparaju et al 2021;Suraparaju and Natarajan 2021a) studied the influence of absorber basin with bottom solid fins and hollow fins inserted in energy storage (paraffin wax) on the freshwater yield of solar still. It was found that the solar still with solid finned absorber inserted in energy storage enhanced productivity by 24.26% compared to CSS.…”

The prime intention of the current research is to enhance the freshwater productivity of the solar still (SS) by using Luffa acutangula fibres (LAF). The dried LA fibres were introduced into the absorber basin of solar still to enhance the wet surface area through its porous structure that leads to augmented evaporation of water from the absorber basin. The effect of the number of LAF in absorber basin such as 10,13,14,15,16,20 and 25 on freshwater productivity was estimated. The results revealed that SSLAF with 15 fibres in the absorber basin increased the yield by 25.23%. Besides, solar still with 10,13,14,16,20 and 25 fibres in the absorber basin increased the yield by 12.27%, 17.45%, 22.04%, 22.69%, 14.64% and 4.09% respectively when compared to conventional solar still (CSS). The average thermal efficiency of the SSLAF with 15 LAF was increased by 28.35% whereas, for 10,13,14,16,20 and 25 LAF, the average thermal efficiency was increasedby 11.05%, 16.99%, 22.53%, 19.93%, 11.29% and 3.9% respectively when compared to CSS.The economic analysis resulted that the cost per litre freshwater yield from the SSLAF is 22.5% lower than CSS. Also, the payback period of SSLAF is comparatively lesser than that of CSS.
