[0037] The environmental detector 8 can detect and collect environmental parameters such as air quality, temperature and humidity, and wind speed; the environmental detector 8 is connected to a data acquisition controller 11, and the detected environmental data is displayed on a display 10 of the photovoltaic tree through the data acquisition controller 11.

[0038] The data acquisition controller 11 also includes a remote communication module, which can transmit the operation status of the photovoltaic tree, real-time power data, system temperature and ambient light data to a remote server or a user's mobile device for real-time monitoring and remote control. The data acquisition controller 11 further manages the distribution and storage of the electric energy generated by the photovoltaic panel 2: when the electric energy generated by the photovoltaic panel 2 exceeds the real-time consumption demand, the excess electric energy is stored in the battery 9 and connected to the power grid; when the light is insufficient or at night, the data acquisition controller 11 will draw power from the battery 9 to supply the LED light 12, the display screen 10 and the rotating mechanism 5 to ensure the continuous operation of the system.

[0039] In the present invention, the model of the environment detector 8 may be YF-IAQM-V1; the photosensitive sensor 6 may be an Omron photoelectric sensor; and the model of the angle sensor 7 may be WDD3504.

[0040] Specifically, in this embodiment, the three-dimensional bracket 2 adopts a ring-shaped ascending arrangement so that the photovoltaic panels 1 are arranged in a spiral or ring-shaped ascending manner from bottom to top along the bracket, which can optimize space utilization and allow the photovoltaic tree to install more photovoltaic panels in the vertical space, which is suitable for places with limited environment and space.

[0041] Furthermore, in this embodiment, the rotating mechanism 5 is a gear rotating device driven by a stepper motor, connected to the three-dimensional bracket 4 through a bearing, capable of accurately controlling the rotation angle of the photovoltaic panel 2, and having the characteristics of low energy consumption.
