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.
