“…The wick material act as the porous medium in the absorber basin. The wick material increases more wet surface area, resulting in more evaporation (Fale et al 2021) (Shubhajyothi et al 2020). Sharshir et al (Sharshir et al 2020c) investigated the still with a novel wick-metal chip pad.…”

The objective of the work is to investigate the single slope solar still for the enhancement in productivity by the inclusion of optimum weight of palm flower powder of micro-sized in the absorber basin and optimum weight% of micro-Phase Change Material (mPCM) under the absorber basin. In this regard, the effect of different weights of palm flower powder such as 10, 30, 45, 50, 55, 70, 100, 120 and 150 g in the absorber was analysed. The solar still with 50 g of palm flower powder in the absorber increased the productivity by 37.25% whereas, for 10, 30, 45, 55, 70, 100, 120 and 150 g were 11.85, 24.78, 36.1, 36.8, 34.35, 33.05, 10.25 and -20.22% respectively. The effect of different weight% of micro-sized palm flower powder such as 5, 10, 15 and 20 wt%, in paraffin wax, was investigated. The paraffin wax with 20 wt% of micro-sized palm flower powder has a better thermal conductivity of 0.33 W/mK. The experimentation was carried out with 50 g of micro-sized palm flower powder in the absorber basin and 20 wt% mPCM under the absorber basin solar still (PCMPFP-SS) and Conventional Solar Still (CSS). The overall yield of PCMPFP-SS was 4670 ml/m2-day on day 1 and 4250 ml/m2-day on day 2, for CSS it was 3030 ml/m2-day on day 1 and 2800 ml/m2-day on day 2. It was evaluated that the Cost per Litre of PCMPFP-SS was $ 0.025 and $ 0.032 for CSS.

“…The result elucidated that the recirculatory flow arrangement in the inclined distiller enabled to produce 4.43 L/m 2 .day of freshwater and the corresponding efficiency was approximately 43.99%. A shallow basin wick-type SDS was designed to augment for solar evaporation (Shubhajyothi et al 2020). The experiment was conducted at Coimbatore (11.0168°N, 76.9558°E) under Indian climatic conditions from June 2010 to May 2011.…”

The sun is the primary source of life on the earth. The heating effect of the sun provides a more fruitful environment for mankind. In addition, solar energy in the form of thermal radiation has been utilized for solar thermal applications and space heating. With abundant solar radiation, the emergence of the solar desalination has been emerged as a viable solution for water purification by utilizing solar stills. However, solar-powered distillation is relatively a slow process due to the requirement of bulk heating. To suppress thermal conduction to bulk water, various photothermal materials were employed. However, there are many governing parameters which influence the productivity, including solar intensity, cloud, wind, ambient air temperature, humidity, solar absorption of blackened surface, depth of bulk water, feed water type, angle of condensation surface, water film thickness, underneath the condensing surface, and experiment period. Further, systematic and continuous experiments for extended periods are essential for determining the stability and durability of a solar desalination system. The main objective of this article is to review all the experimental studies conducted for two months at minimum up to 1-year duration. In addition, all the SDSs handled in this study further were examined by solar geometrical factors, including day length (DL) and position of the sun or zenith angle (θ z ). As a result, the sunshine hours, day length, and the solar zenith angle play an important role in the water evaporation rate. Lower solar zenith angle and longer day length (more sunshine hours) are desirable for higher water productivity.

An Experimental investigation had been executed in a solar distill unified with parabolic collector using PCM. This experiment had been compared with PCM less experimental setup. PCM and Parabolic solar collector are things embedded with the base system to increase the overall outcome. Used paraffin wax as PCM (Phase Change Material) was one of the most cost-effective approaches to store heat energy. The solar ray’s incidence had been harvested by using the solar distill in which the water passed by the water tubes. This base solar still consist of double slope and the water tube filled with PCM. These experiments were done at the water depth of 15 mm. In these experiments produce the results indicated that a solar distillation system with a Parabolic Solar Collector coupled with PCM yielded higher productivity and temperature levels compared to not utilizing PCM, and these experiments demonstrated that the introduction of PCM in DSSD with Parabolic solar collector with or without it PCM resulted the improvements of the productivity of 33.25% and 57.31% respectively.
