“…In 2020, active desalination techniques progressed (Singh et al 2020), and tubular-shaped distillers (Kabeel et al 2020;Thalib et al 2020) were developed. Recently, materials for solar desalination (Akkala et al 2021;Alarifi et al 2021;Arani et al 2021;Attia et al 2021b;Peng et al 2021), NFs (Essa et al 2021;Iqbal et al 2021), and wick-type distillers (Jobrane et al 2021;Maheswaran et al 2021) were investigated. However, there are no reviews which exclusively focused on the solar geometry-based analysis for the stability of SDSs during a long period of experiments.…”

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.
