Among them, the support frame 1 mainly plays a supporting role. The function of the above-mentioned reflective layer 3 is to reflect other light beams and emit the light beams to the back of the photovoltaic panel 4 to further improve the photoelectric conversion efficiency.

Further, in this embodiment, the above-mentioned photovoltaic panel 4 is provided with an automatic adjustment device (not shown in the figure), which is used to adjust the angle of the photovoltaic panel 4 and adjust the angle of the photovoltaic panel 4 according to the angle of the beam emitted by the sun. , so that the front surface 401 of the photovoltaic panel 4 is always perpendicular to the sun beam.

The sensor converts the received light beam signal into an electrical signal. The signal can further perform various switching and control actions. The basic principle is to shield the light beam between the emitter and the receiver, and the obtained signal is used to complete the control of the drive motor.

In some implementations of this embodiment, the above-mentioned reflective layer 3 is made of stainless steel. Stainless steel is steel that is not easy to rust. In fact, some stainless steels have both rust resistance and acid resistance (corrosion resistance). The rust and corrosion resistance of stainless steel is due to the formation of a chromium-rich oxide film (passivation film) on its surface. This rust resistance and corrosion resistance are relative. Tests show that the corrosion resistance of steel in weak media such as atmosphere and water and in oxidizing media such as nitric acid increases with the increase of chromium content in steel. When the chromium content reaches a certain percentage, the corrosion resistance of steel changes abruptly. , that is, from easy to rust to not easy to rust, and from corrosion-resistant to corrosion-resistant. Therefore, the selection of stainless steel material can not only greatly improve the corrosion resistance of the reflective layer 3, but also prevent collision. The stainless steel material is not easy to deform, which can ensure that the reflective surface is not damaged.

Specifically, 316 stainless steel material is selected in this embodiment.

The included angle between the reflective layer 3 and the photovoltaic panel 4 is controlled to be between 30° and 40°, which can ensure that the reflected light beams can be well converted into photoelectricity and improve the power generation efficiency.

In some implementations of this embodiment, the angle between the above-mentioned reflector 2 and the above-mentioned photovoltaic panel 4 is between 15° and 30°. The angle between the reflector 2 and the photovoltaic panel 4 is controlled between 15° and 30°, so that the reflector 2 can fully reflect the light beam to the back of the photovoltaic panel 4 and improve the photoelectric conversion efficiency.

In some implementations of this embodiment, the above-mentioned reflector 2 has an arc-shaped structure. The arc-shaped structure of the reflector 2 can play a certain role in focusing, and can reflect the light beam to the back of the photovoltaic panel 4 in a concentrated manner. This structure can collect and reflect more light beams, so that the back of the photovoltaic panel 4 can receive more light energy.

In some implementations of this embodiment, the arc surface of the arc structure is between R550˜R640.

When in use, the above-mentioned photoelectric sensor senses changes in the intensity of sunlight and generates electrical signals. The electrical signal is transmitted to the above-mentioned controller, and the controller controls the above-mentioned driving motor to drive the rotating shaft 6 to rotate according to the logic judgment, so that the reflector 2 rotates toward the strong light. When the sun beam irradiates the front surface 401 of the photovoltaic panel 4, the photovoltaic panel 4 starts to work and performs photoelectric conversion. At the same time, around the photovoltaic panel 4, the light beam reflected by the reflector 2 is reflected to the back of the photovoltaic panel 4, so that the back of the photovoltaic panel 4 also receives the light to perform photoelectric conversion. Similarly, the reflective layer 3 on the support frame 1 can also emit a part of the light beam, so that the speed of light is reflected on the back of the photovoltaic panel 4, and the photoelectric conversion efficiency is further improved.

Ordinary solar photovoltaic panels 4 generally have only one side for receiving solar beams and converting solar energy into electrical energy.
