Salt gradient solar ponds are simple and low cost solar energy system for collecting and storing solar energy. In this study, heat storage characteristic of urea and borax solutions in the solar pond were examined experimentally. Establishing density gradients in different concentration, variations in the temperature and density profiles were observed in four different experiments. Maximum storage temperatures were measured as 28 degrees C and 36 degrees C for the ponds with urea and borax solution, respectively. The temperature difference between the bottom and the surface of the pond were measured as 13 degrees C for urea and 17 degrees C for borax-solutions. According to these results, heat storage characteristic of the solar pond with borax solution was found to be better than urea solution.
