Ways to implement the invention

[0005] Fig. 1 shows a schematic view according to a first embodiment of the present invention. It comprises a solar tracking unit 20 and a solar power generation unit 10, which comprises a solar module mounting bracket 11 and a plurality of solar modules 12, wherein the solar module mounting bracket 11 has a horizontal plate section 111, a first vertical plate section 112 arranged upwards on one side of the horizontal plate section 111, and a second vertical plate section 113 arranged on the other side of the horizontal plate section 111 and opposite the first vertical plate section 112. The solar modules 12 are arranged vertically spaced between the first vertical plate section 112 and the second vertical plate section 113.Each solar module 12 includes a solar panel mounting bracket 121, each of whose two ends are pivotally mounted on the first vertical plate portion 112 and the second vertical plate portion 113 to adjust the tilt angle. An upwardly facing first solar panel 122 is arranged on the top side of each solar panel mounting bracket 121, and a downwardly facing second solar panel 123 is arranged on the bottom side of each solar panel mounting bracket 121. A first reflector 13 is arranged on the left side of each first solar panel 122, and a second reflector 14 is arranged on the right side. Both the first reflector 13 and the second reflector 14 are oriented obliquely.The right side of the first reflection device 13 forms a first reflection surface 131, wherein the included angle between a respective first reflection surface 131 and the corresponding first solar panel 122 is greater than 90° and less than 135°. The left side of the second reflection device 14 forms a second reflection surface 141, wherein the included angle between a respective second reflection surface 141 and the corresponding first solar panel 122 is greater than 90° and less than 135°.

[0006] The solar tracking unit 20 is arranged below the solar power generation unit 10 and includes a mounting base 21, a circumferential angle rotation module 22, a circumferential angle rotation platform 23, and an elevation angle rotation module 24. The mounting base 21 is located at the lowest level, a circumferential angle rotation module 22 is arranged on the mounting base 21 and serves to adjust the circumferential angle of the solar tracking unit 20 and to adapt to the azimuth angle of the sun, and a circumferential angle rotation platform 23 is arranged above the circumferential angle rotation module 22 and serves to mount and fix the solar module mounting bracket 11 and thereby support the solar power generation unit 10. The circumferential angle rotation platform 23 is driven by the circumferential angle rotation module 22, thereby driving the entire solar module mounting bracket 11 to rotate to adjust its angle and the circumferential angles of the solar modules 12.The elevation angle rotation module 24 includes an elevation angle bracket 241 located outside the second vertical plate portion 113 and a plurality of elevation angle driving devices 242 matched to the corresponding solar modules 12, one side of which is connected to the corresponding solar panel mounting bracket 121 to output the power of the elevation angle driving devices 242 and thus rotate the solar panel mounting brackets 121 and adjust the elevation angles of the solar modules 12.

[0007] It will be Fig. 2. When the light 31 of the sun 30 hits a solar panel at an angle, the oblique sunlight 31 leads to a decrease in the amount of power generated. The more oblique the angle of the light, the worse the power generation efficiency. Since a solar panel can achieve the maximum irradiation angle and the maximum amount of power generated when it is directly facing the sun, the sun tracking unit 20 first adjusts the angles of the first solar panels 122 so that they face the sun 30 to achieve the goal of maximum power generation. In addition, the reflected sunlight 31 can be directed to the corresponding first solar panels 122 by both the first reflection surfaces 131 and the second reflection surfaces 141 to increase the amount of power generated by the first solar panels 122.Furthermore, the second solar panels 123 can absorb the ambient light 32 for power generation, thereby increasing the overall power generation efficiency of the solar modules 12. To increase the amount of power generated, additional solar modules 12 can be stacked upward at intervals. The width between a respective first reflection device 13 and the corresponding second reflection device 14 is equal to the width of the corresponding first solar panel 122, with the reflection effect increasing with height.

[0008] Fig. 3 shows a second embodiment of the present invention, which differs from the first embodiment in that a third reflection device 15 is arranged on the left side of a respective second solar panel 123 and a fourth reflection device 16 on the right side, wherein both the third reflection device 15 and the fourth reflection device 16 are oriented obliquely, the right side of the third reflection device 15 forms a third reflection surface 151 and the included angle between the third reflection surface 151 and this second solar panel 123 is less than 45°, wherein the left side of the fourth reflection device 16 forms a fourth reflection surface 161 and the included angle between the fourth reflection surface 161 and this second solar panel 123 is less than 45°. As in Fig. 4, the sunlight 31 can be reflected by the third reflection surfaces 151 and the fourth reflection surfaces 161 onto the corresponding second solar panels 123 to increase the power generation amount of the second solar panels 123.

[0009] Fig. Figure 5 shows a third embodiment of the present invention, which differs from the first embodiment in that the solar power generation unit 10 is not equipped with second solar panels 123. This embodiment is suitable for locations where the ambient light on the ground or near the ground is weak, because in weak ambient light on the ground or near the ground, the power generation efficiency of the second solar panels 123 is low. In this case, the second solar panels 123 can be removed.

[0010] Fig. Figure 6 shows a fourth embodiment of the present invention, which differs from the first embodiment in that only a first reflection device 13 is mounted on one side of a respective first solar panel 122. The purpose is that if the reflection effect is already excellent, there is no need to mount another reflection device on the other side.

[0011] Fig. Figure 7 shows a fifth embodiment of the present invention, which differs from the first embodiment in that no reflection device is mounted in the present embodiment. This embodiment is suitable when space is limited and the overall area of ​​the device needs to be reduced to reduce the space required for the solar module mounting bracket 11.

[0012] Fig.8 shows a sixth embodiment of the present invention, which differs from the first embodiment in that a third solar panel 124 is arranged on the outside of the first vertical plate section 112 in order to fully utilize the ambient light 32 and thus increase power generation.

[0013] Although the invention has been described in terms of the preferred embodiments, it will be apparent to those skilled in the art that modifications may be made to the invention within the spirit and scope of the appended claims.
