[0006] Figure 1 is a schematic diagram showing the structural features of the first embodiment of the present invention. The present invention includes a photovoltaic unit 10 and a solar tracking unit 20. The photovoltaic unit 10 mainly includes a solar module mounting bracket 11 and a predetermined number of solar modules 12.
[0007] The solar module mounting bracket 11 includes a horizontal plate portion 111. A first plate support portion 112 is provided on one side of the horizontal plate portion 111, and a second plate support portion 113 is provided on the other side of the horizontal plate portion 111.
[0008] The solar cell module 12 is arranged between the first plate support portion 112 and the second plate support portion 113 with a vertical gap therebetween. The distance between adjacent solar modules 12 is set so as not to collide with each other (even if the solar modules 12 rotate, they do not interfere with each other). The solar cell module 12 has a solar panel mounting bracket 121. Both ends thereof are pivotally attached to the first plate support portion 112 and the second plate support portion 113, and the inclination angle is adjustable. A first solar panel 122 is installed on the upper surface (top) of the solar panel mounting bracket 121, and the front surface of the first solar panel 122 faces upward. Also, a second solar panel 123 is installed on the lower surface (bottom) of the solar panel mounting bracket 121, and the front surface of the second solar panel 123 faces downward.
[0009] A first reflection device 13 is arranged on the left side of the first solar panel 122, and a second reflection device 14 is arranged on the right side. The first reflection device 13 and the second reflection device 14 are inclined. The right side of the first reflection device 13 is a first reflection surface 131. The angle between the first reflection surface 131 and the first solar panel 122 is greater than 90 degrees and less than 135 degrees. The left side of the second reflection device 14 is a second reflection surface 141. The angle between the second reflection surface 141 and the first solar panel 122 is 90 - 135 degrees.
[0010] The solar tracking unit 20 is arranged below the solar power generation unit 10 as in the prior art. Hereinafter, its structure and functions will be briefly described. The solar tracking unit 20 mainly includes a mounting base 21, an angular rotation module 22, an angular rotation platform 23, and an elevation rotation module 24. The mounting base 21 is located at the bottom layer and can be installed and fixed on the ground, a building, or other load-bearing objects according to the actual on-site situation. An angular rotation module 22 for adjusting the circumferential angle (angle) of the solar tracking unit 20 to match the azimuth angle of the sun is provided on the upper part of the mounting base 21. An angular rotation platform 23 for installing and fixing a solar module mounting bracket 11 for supporting the solar power generation unit 10 is provided on the upper part of the angular rotation module 22. The angular rotation module 22 drives the angular rotation platform 23, rotates the entire solar module mounting bracket 11 to adjust the circumferential angle (angle), and thereby synchronously adjusts the circumferential angle (angle) of the solar module 12.
[0011] The elevation rotation module 24 includes an elevation bracket 241 and a predetermined number of elevation driving devices 242. The elevation bracket 241 is located outside the second plate support portion 113, and the elevation driving devices 242 are arranged corresponding to the solar module 12. One side of each elevation driving device 242 is engaged (attached) with the solar panel mounting bracket 121. By driving the elevation driving devices 242, the solar panel mounting bracket 121 can be rotated, and the elevation angle of the solar module 12 can be synchronously adjusted.
[0012] Figure 2 is a schematic diagram of the usage state of the first embodiment of the present invention. Since the solar panel can obtain the maximum amount of light and generate the maximum power when facing the sun 30 directly, when the solar panel is at an oblique angle to the sun 30, the power generation amount decreases due to the oblique sunlight 31. The larger the oblique angle, the worse the power generation efficiency. Therefore, first, in order to achieve the goal of maximum power generation, the solar tracking unit 20 adjusts the angle of the first solar panel 122 to face the sun 30. Next, since both the first reflecting surface 131 and the second reflecting surface 141 can project the reflected sunlight 31 onto the first solar panel 122, the output of the first solar panel 122 can be further increased. In addition, the second solar panel 123 absorbs the ambient light 32 and generates electricity, which can improve the power generation efficiency of the entire solar module 12. At this time, the power generation efficiency of a single solar module 12 is superior to that of a solar panel by the conventional installation method.
[0013] In some embodiments, preferably, as a result of being able to stack and install more solar cell modules 12 at intervals upward, the unit power output of the present invention can be several times that of the conventional structure disclosed above.
[0014] In some embodiments, preferably, the first and second reflecting devices 13 and 14 are preferably rectangular in shape, and their widths can coincide with the width of the first solar panel 122. The larger the height, the better the reflection effect.
[0015] Referring to FIG. 3, the difference between the second embodiment and the first embodiment of the present invention is that a third reflecting device 15 is provided on the left side of the second solar panel 123, and a fourth reflecting device 16 is provided on the right side. The third reflecting device 15 and the fourth reflecting device 16 are inclined. The right side of the third reflecting device 15 is the third reflecting surface 151, and the angle between the third reflecting surface 151 and the second solar panel 123 is greater than 0 degrees and less than 45 degrees. The left side of the fourth reflecting device 16 is the fourth reflecting surface 161, and the angle between the fourth reflecting surface 161 and the second solar panel 123 is greater than 0 degrees and less than 45 degrees. As shown in FIG. 4, using the first and second reflecting surfaces 131 and 141, the sunlight 31 is reflected onto the second solar panel 123, increasing the illuminance of the second solar panel 123, thereby increasing the power generation per unit area.
[0016] Preferably, in order to enhance the reflection effect, a layer of high-reflection material or a high-gloss surface treatment may be added to the first reflecting surface 131, the second reflecting surface 141, the third reflecting surface 151, and the fourth reflecting surface 161 to enhance the reflection effect.
[0017] In some embodiments, the third reflecting surface 151 and the fourth reflecting surface 161 may be coated with a layer of high-reflection material to enhance the reflection effect.
[0018] Next, referring to FIG. 5 for the third embodiment of the present invention, the difference from the first embodiment is that the solar power generation unit 10 may not include the second solar panel 123. When the ambient light on the ground or at the bottom is weak or the power generation efficiency of the second solar panel 123 is not good, this embodiment is suitable for use in places where the ambient light on the ground or at the bottom is weak. In this case, the second solar panel 123 can be removed to save the installation cost.
[0019] FIG. 6 shows the fourth embodiment of the present invention. The difference from the first embodiment is that the first reflecting device 13 is installed only on one side of the first solar panel 122, intending that when the reflection effect on one side is already excellent, there is no need to install a reflecting device on the opposite side.
[0020] Figure 7 shows the fifth embodiment of the present invention. The difference from the first embodiment is that no reflection device is provided in this embodiment. The application situation is that when it is necessary to reduce the occupied area of the entire device due to space limitations, the occupied area of the solar cell module mounting bracket 11 can be reduced according to the local situation.
[0021] Finally, regarding the sixth embodiment of the present invention, referring to FIG. 8, the difference from the first embodiment is that by arranging a third solar panel 124 of a predetermined size outside the first plate support portion 112, the environmental light 32 can be utilized to the maximum extent to increase the power generation amount.
