Two major challenges for human society today are shortage of fresh water and limited resources of conventional energy. Solar still is one of the methods to convert saline, brackish water into fresh water using the unconventional source of energy, i.e. solar energy which is free and abundantly available in planet earth. The common method using in the solar still is active and passive solar still According to the basics of design solar still are classified into single slope solar still and multi slope solar still. In the active type solar still the external sources are used while in the case of passive solar still there is no need to use external sources. Most important design parameters influencing the productivity are optimally of glass inclination, the intensity of solar radiation, absorber plate area, thickness of glass cover, the basin filled with different materials, Nano particles mixed with water in the basin, a free surface area of water and depth of water etc. The main difficulty with conventional still is maintaining minimum depth and large surface area of water. Researchers have put efforts to develop various designs of solar stills to maintain the minimum depth of water using different types of materials in the stills to increase the productivity. In the present work, experiment was carried out on double slope, single basin passive solar still filled with water, water with aluminum and water with granite to study the performance analysis of a solar still at different depth of water. During the experiment, it was observed that the maximum productivity and thermal efficiency were obtained in the case of granite with respect to others.
