An experimental wick-type solar still system: Design and construction

► A tilted wick-type solar still unit was designed and constructed. ► The effect of input water flow rate and salinity on the still productivity together with the variation of the solar still efficiency and absorber temperature have been investigated. ► The representative daily efficiency of the still was about 53% on clear days in summer. ► The still efficiency decreased linearly with increase of salinity of the input saline water.
