Effect of Glass Cover Thickness and Inclination Angle on Distillate Efficiency of Single-Stage Solar Still

Abstract Solar desalination is one of many methods to separate excess salt from seawater. In this work, solar energy applied because its economical and environmental value. Additionally, practical use in the coastal region. To increase distillate produced by still, four variations cover thickness three inclination angle are still. The used work 3 mm, 5 8 10 mm 25°, 30°, 45°. type still that a rectangular-shaped single-stage with an area 0.8 m 2 . processes were done 09.00 until 16.00 data was collected every hour processes. result shows efficiency 1.03% - 6.91%. highest intensity 1231.97 W/m lowest 101.03 most effective obtained variation 25° angle, while 30° angle.
