In view of the general lack of electricity and power in mountainous areas, the establishment of communication base station systems with multiple line lengths and the use of traditional public power grids for power supply are not only difficult to construct but also costly to support. As a new green energy source, solar power has developed rapidly in developed countries and has been widely used. At present, the use of solar power has its unique advantages for multi-line long power applications such as communication base stations and places lacking power far from the power grid.
