Abstract

Graphical abstract: Highlights: For optimal condensation, the glass cover thickness should be between 3 and 5 mm. Single slope solar still is preferable for a place with a latitude higher than 20°. Through vacuum technology, the production increases in a severe weather scenario. Al2 O3 Nano particles coating on absorber will increase yield by 20%-50% The choice of the PCM depends on the maximum water temperature. Abstract: Around 97% of the total water available on the earth is saline or brackish and hence, not suitable for direct consumption. There are number of distillation process to convert the saline or brackish water into potable using different techniques, basin type solar still is one of them which is the cheapest, easiest and effective solutions to fulfil the demand of freshwater particularly, for rural and remote areas. However, there are limitations for basin-type solar still which restricts its performance and several (experimental and numerical) studies has discussed the improvements in design and operational strategies. Therefore, this article presents the comprehensive literature survey of solar desalination systems including the design, operational, and environmental characteristics and their impact not only on the performance but also on the quality of water produced from the conventional solar stills. Further, the limitations along with the recommendations for future work, which may enhance the performance and productivity of basin solar still for typical operating conditions are also mentioned.
