Abstract : The efficiency for a passive single-slope type solar still used for desalination and distillation is very low. Most of the available methods are either very costly or very slow in the rate of production. Many studies were conducted to improve the rate of production from the still. In this proposed work, a study on thermal storage elements like pieces of aluminum sheet and galvanized iron sheet with sponge cubes have been performed along with a comparison to the normal plain basin with only sponges. The study is further extended to know the enhancements in efficiency with preheating of the inlet water. In water scarce area, this could be really helpful because of the increased rate and reduced cost of production. A cost analysis has also been carried out to determine the payback period for the proposed system. © 2017 IEEE.
