Abstract

This work focused towards an experimental investigation by comparing the performance of two solar still such as pyramid solar still and hemispherical solar still. The comparative performance study is analyzed for same weather conditions with different design parameters. The same area is maintained for the both the solar stills as 1 m2. The analysis is based on the distillate yield rate due to top cover structural arrangement of both the stills. Operational parameters such as ambient, inner, outer cover temperature, water, air and productivity have been predicted. The efficiencies of these solar stills conformed that the distilled water output of the hemispherical solar still was higher than the pyramid type solar still. Performance characteristic of the hemispherical solar still showed temperature at the water surface is closely related to the more incident radiation. The productivity is due to receiving the radiation from the top cover without any loss.
