By taking advantage of the obtained experimental data, the impact of employing concentrating solar collectors, using an electric heater, and changing the water height in the basin on the performance of a hybrid solar still system was investigated. Eight different operating modes for the system were studied, while the daily freshwater production in addition to the cost per liter (CPL) was considered as the performance criteria. According to the results, the best height of water in the basin is 10 mm. It is the lowest examined height. Moreover, it was found that using the hybrid system with both electric heater and concentrating solar heater brings considerable improvements compared to the other investigated operating modes. For the climatic condition of Sirjan, Iran, which is where the experiments were performed, and water height in the basin of 10 mm, using the hybrid system in the active mode results in 8178 mL/m2 of fresh water production, and a CPL of $0.04270 per liter.

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.

In this current study, a single basin solar still (SBSS) was explored in the climatic state of Patan (23.84° N, 72.12° E) India over March 2019. The SBSS was examined with the use of waste brick magnesia (WBM) for the same amount of water (10 L). For experimentation, three same‐sized SBSS were taken with 3 and 6 kg WBM and without storage materials. It was found that a daytime yield for SBSS of 2.27 L without storage materials was obtained; and this was reduced for SBSS with 3 and 6 kg WBM to 1.96 and 1.75 L, respectively. It has also been noticed that the yield of SBSS during off‐sunshine hours due to the energy storage capacity increased with WBM but the combined (daytime + off‐sunshine hours) yield was found reduced with an increment in a mass of the WBM. It was found that the maximum instantaneous thermal efficiency of the SBSS without WBM, 3 and 6 kg WBM was 60.24%, 45.65%, and 54.26%, respectively. Overall thermal efficiency was also determined and obtained to be higher for SBSS without WBM as storage.
