Abstract—In order to improve the availability of solar energy, this paper introduces a new solar energy storage device and its parameters automatic measuring system. The device puts the heat which was gathered by synchronous tracking solar collector into underground concrete storage pile. Meanwhile, the system could simultaneously measure the temperature, pressure and flow of the device, etc. Some derived parameters such as thermal energy storage and thermal storage effectiveness can be obtained by calculation. According to the experimental results, the device is able to store the solar energy for seasons in the underground, and automatic measuring system could display the parameters and real-time curves on monitor and draw the history curves of all parameters. The data base of parameters could be built during the energy storage process. Furthermore, the energy storage report can be generated to obtain an automatic and digital energy storage process.
