Performance measures of an active, small scale solar basin still in terms of production cost an energy efficiency

Abstract

The research investigated the characterisation of a cost-effective active solar still by implementing active solar still recommendations suggested by Marais (2018) and external condenser design improvements identified in the research work. Marais’ (2018) still variation 3 was used to design a solar still to improve still productivity performance: • By using an external condenser that will reduce the available condensation area and drive condensation away from the cover surface. • By using active fluid flow to circulate humid air and, or water through the solar still. • By reducing energy losses of the cover surface and energy accumulation of the back wall.
