A practical study of a single-slope solar still with a new design: a comparative study.

In this article, an attempt was made to design and manufacture a newly developed single-slope, single-basin solar still with a semicircular design. The proposed semicircular solar still (SSS) was tested alongside a conventional solar still (CSS) made with the same materials and the same absorption plate area. The results showed that the maximum yield of the semicircular still increased by about 104% compared to the traditional solar still. This increase in production, along with the stability in the cost of manufacturing the solar distillation device, led to a decrease in the cost of producing a liter of fresh water from about 0.0332 to 0.0166 dollars, that is, a reduction of up to 50%.
