Places for solar power generation, such as rooftops or open areas.

At present, household mounting brackets for solar panels include a mounting base, a fixing frame is arranged on the mounting base, and a supporting plate for fixing solar panels is arranged on the fixing frame. After the existing mounting brackets are installed, the solar energy The orientation of the solar panel is fixed and there is only one orientation, which leads to the fact that within a day, the sun can only shine on the front of the solar panel during a period of time in the morning or afternoon, and the sun cannot shine in the rest of the time. Therefore, power generation cannot be performed, and the power generation process is discontinuous, which will lead to less power generation of the entire power generation device and cannot meet normal needs. If the power generation is to be increased, the method of adding solar panels is usually used, and adding a solar panel Just must reinstall a mounting bracket, make the power generation cost increase greatly.
