Solar pond is the simplest technique of the direct conversion of solar energy into thermal energy, and it is a solar collector and a solar thermal storage at the same time. It is known that any watery basin can absorb the radiation and convert it into heat, but most of the natural basins lose heat quickly due to phenomenon of convection within the basin, evaporation and thermal conduction across the surface of the basin, so a basin with a gradual concentration of salinity will be able to prevent the effect of convection and prevents evaporation and thermal conduction across the surface of the basin too. Because of the large thermal storage capacity of the solar pond and after take some procedure to reduce the thermal losses a typical solar pond takes several weeks to lose only 10 deg. Celsius even in the absence of the solar radiation, thus the solar pond converts intermittent solar energy into a reliable and continuous source of energy. A preliminary design and thermal study of a solar pond used to heat a tourist hotel was explained in this research.
