In order to solve the problem of huge electricity demand in the tailings ecological restoration process, according to the natural conditions of the tailings area, combined with the rich characteristics of renewable natural resources, the integrated system of solar energy and storage is designed and analyzed with examples. Considering the complex terrain characteristics of the mining area, the multi-channel MPPT photovoltaic array is selected to adapt to the complex terrain environment for power generation, and the energy storage unit is added for peak shaving. While solving the problem of power shortage in local ecological restoration, the impact of the system on the fluctuation of the grid voltage is alleviated. Finally, a typical application analysis of a tailing mine in Chuxiong City, Yunnan Province was carried out to discuss the rationality of the designed system. The results show that the designed system can effectively alleviate the power consumption problem in the ecological restoration of mining areas, which provides an important reference value for the ecological restoration of similar tailings areas and has certain popularization.
