The solar photovoltaic panel 6 is made of monocrystalline silicon. The utility model detects the intensity of sunlight through the photoelectric sensor 4, and the control circuit of the controller drives the inclination angle rotating device 5 to change the inclination angle of the solar photovoltaic battery panel 6, so that the angle can be changed according to the intensity of light, so as to obtain the maximum illumination time, which is different from the traditional Compared with the fixed module of photovoltaic panels, the power generation can be increased by 30%.

The utility model is driven by a small motor in the inclination angle rotating device 5 to change the inclination angle, and the design circuit is relatively simple. Specifically as shown in Figure 1, the utility model includes a light pole 1 connected to a lamp 3, which is characterized in that: the top of the light pole 1 is provided with a solar photovoltaic panel 6 for photoelectric conversion and supplies power to the lamp 3 through the equipment box 2; The top of the pole 1 is provided with a photoelectric sensor 4 to collect the sun's irradiation angle and then controls the inclination rotation device 5 to drive the solar photovoltaic panel 6 to rotate the angle, so as to achieve the best collection effect of solar energy.
