Solar ponds represent a renewable energy technology that collects and stores thermal energy for diverse heating and cooling purposes. By coupling a solar pond with a solar still, the stored thermal energy can deliver preheated water directly to the distillation setup, effectively increasing freshwater output. Different system configurations, including shallow and mini solar ponds, have been coupled with solar stills to enhance operational productivity. Synthesised evidence demonstrates that integrating solar ponds reliably boosts the distillation yield of solar stills compared to unassisted units. Ongoing research efforts continue to explore these paired thermal designs to expand their effectiveness in solar water purification.
Solar stills offer an environmentally sustainable method for purifying water, but their baseline yields are often modest. Utilising solar ponds to collect and store heat provides a consistent thermal boost for distillation units, making solar-powered water purification more productive without relying on conventional fuels.
The integration of solar ponds with solar stills targets solar-powered water purification and distillation systems, which could benefit off-grid communities and thermal utility operators. As the underlying findings derive from a review covering experimental designs such as mini and shallow ponds, the approach appears to be at an applied research stage and requires further development before commercial deployment.

Abstract A solar pond (SP) is a remarkable growth of renewable energy technology that has stored solar energy for storage purposes and is used in many solar thermal applications. It is also utilized for many purposes, such as heating, cooling, space heating, air conditioning, and many more. The present paper shows the use of an SP to improve the yield of solar still (SS) by providing hot water through the heat energy stored in it. It also reveals the use of shallow and mini SPs with SS to improve yield. Various future research works on SS using SPs have also been included in this paper. From the current review paper, it was concluded that the SP increases the yield of the SS.
