Please refer to Figure 1 to Figure 3B. 1 is a functional block diagram of a solar module in a solar device according to an embodiment of the present invention. 2A and 2B are schematic views showing the appearance of a solar device 1 according to a first embodiment of the present invention. FIG. 3A and FIG. 3B are schematic diagrams showing the appearance of a solar device 1 according to a second embodiment of the present invention.

The solar device 1 includes a first base 14 and a solar module 15 pivotally connected to the first base 14. The solar module 15 and the first base 14 have an elevation angle θ between the solar module 15 and the sunlight. Has an azimuth angle.

The solar module 15 includes a first indicating device 12, a second indicating device 13, a control unit 11, and a solar panel 10. The control unit 11 is coupled to the first indicating device 12, the second indicating device 13 and the solar panel 10, respectively, and the control unit 11 controls the indication states of the first indicating device 12 and the second indicating device 13. In a specific embodiment, the control unit 11 is disposed in the first base 14.

The solar module 15 and the first base 14 are pivotally connected by the rotary bearing 16, and the solar panel 10 is horizontally disposed on the solar module 15. By rotating the bearing 16, the solar module 15 can be rotated in a vertical direction relative to the first base 14 to change the elevation angle of the solar module 15.

In operation, in order to change the azimuth angle between the solar module 15 and the sunlight, the user can directly rotate the first base 14 on the horizontal surface. Alternatively, please refer to FIG. 5 , which illustrates a schematic view of the solar device 1 of the present invention further including a second base 17 . As shown in FIG. 5 , the second base 17 can be disposed under the first base 14 , and the first base 14 is rotatably coupled to the second base 17 , so that the first base 14 can drive the solar module 15 relative to the second base 17 . Rotate.

It can be seen from the above that the elevation angle of the solar panel 10 can be changed by pivoting the solar module 15 to the first base 14 , and the azimuth of the solar panel 10 can be changed by rotating the first base 14 .

It can be known from the ball coordinate system that any direction in the three-dimensional space can be obtained by controlling the azimuth angle 仰 and the elevation angle θ. As shown in FIG. 2A, the geometric center of the solar panel 10 can be set to the origin of the ball coordinate, and the azimuth angle 仰 and the elevation angle θ can be rotated to control the solar panel 10 to any direction.

In practical applications, the solar panel 10 can be a concentrating or non-concentrating solar panel. It should be noted that, if the solar panel 10 is a concentrating solar panel, the solar device 1 may further include a lens disposed on the concentrating solar panel to assist in collecting light onto the concentrating solar panel. In one embodiment, the lens can employ a Fresnel lens.

In the practical application, the first indicating device 12 and the second indicating device 13 can be disposed on the solar module 15 . It should be noted that the first indicating device 12 indicates the light absorption efficiency of the solar module related to the elevation angle, and the second indicating device 13 indicates the light absorption efficiency of the solar module 15 related to the azimuth angle. In one embodiment, the control unit 11 controls the indication state of the first pointing device 12 according to the magnitude of the light absorption efficiency associated with the elevation angle, and controls the indication state of the second pointing device 13 according to the magnitude of the light absorption efficiency associated with the azimuth angle.

In this embodiment, when the elevation angle or azimuth angle of the solar module 15 is adjusted, both the first indicating device 12 and the second indicating device 13 indicate the light absorption efficiency. In the process of adjusting, the elevation state of the solar module 15 can be adjusted according to the indication state of the first indicating device 12; when the azimuth angle of the solar module 15 is adjusted, the indication state of the second indicating device 13 can be quasi.

As shown in FIG. 2A and FIG. 2B, in a specific embodiment, the first indicating device 12 includes a plurality of indicator lights and the second indicating device 13 also includes a plurality of indicator lights. Thereby, the control unit 11 controls the number of lights of the indicator lights of the first indicating device 12 according to the light absorption efficiency related to the elevation angle, and the control unit 11 also controls the second indicating device according to the light absorption efficiency related to the azimuth angle. The number of lights that are 13 of these indicators. Basically, as the light absorption efficiency becomes larger, the number of lights will increase.

FIG. 4A and FIG. 4B are diagrams showing the relationship between the light absorption efficiency and the different elevation angles and azimuth angles in an example, wherein FIG. 4A shows the solar panel elevation angle and the light absorption when the azimuth angle of the fixed solar panel is at a certain angle. The relationship diagram of efficiency, and Figure 4B shows the relationship between the azimuth of the solar panel and the efficiency of light absorption when the elevation angle of the fixed solar panel is at a certain angle.

Generally speaking, when the incident light of the sun is non-positive incident, if the solar panel is turned to have a relative light absorption efficiency with respect to the incident light, the more the deviation from the relative positive incident angle, the lower the light absorption efficiency. And the relationship is a symmetrical function, both for azimuth ψ and elevation θ. The maximum light absorption efficiency value is set to 1, it can be seen that the solar cell receiving angle is closer to the incident light angle, and its light absorption efficiency is increasing.

For example, the solar panel 10 in FIG. 2A is not positively incident with respect to the incident light L, so that the indicator lights of the first indicating device 12 and the indicator lights of the second indicating device 13 are less lit. . In order to improve the light absorption efficiency, the user may first rotate the first base 14 until the indicator lights of the second indicating device 13 have the maximum number of lights, and then rotate the solar module 15 until the indicator lights of the first indicating device 12 Has the most number of lights, as shown in Figure 2B. At this time, the incident light L is incident on the solar panel 10 in the forward direction, so that the solar panel 10 has an optimum light absorption efficiency.

It should be noted that, in practical applications, the elevation angle between the solar module 15 and the first base 14 is adjusted once by a predetermined angle, that is, the elevation angle of the solar panel 10 can be multi-stage adjustment. In addition, the first base 14 is rotated once with respect to the second base 17 by a predetermined angle, that is, the azimuth angle of the solar panel 10 can also be adjusted in multiple stages. Since the elevation or azimuth of the solar panel 10 is only allowed to be adjusted by a predetermined angle (for example, 10 degrees) at a time, the user will find the optimum light absorption efficiency angle more easily and regularly. In addition to the multi-stage adjustment, the elevation or azimuth of the solar panel 10 can also be steplessly adjusted.

It should be particularly noted that when the user only changes the azimuth angle 太阳能 of the solar panel 10, the control unit 11 can transmit the light absorption signal of the solar panel 10 only to the second indicating device 13; similarly, when the user only changes When the elevation angle θ of the solar panel 10 is reached, the control unit 11 can transmit only the light absorption amount signal of the solar panel 10 to the first indicating device 12.

As shown in FIG. 3A and FIG. 3B, in another specific embodiment, the first indicating device 12 includes one indicator light emitting at least two colors of light, and the second indicating device 13 also includes at least two types. One of the above color lights. Thereby, the first indicating device 12 uses the at least two color lights to indicate the light absorption efficiency associated with the elevation angle. Similarly, the second indicating device 13 uses the at least two color ray to indicate the light absorption efficiency associated with the azimuth.

For example, the first indicating device 12 and the second indicating device 13 can emit yellow, orange or red light, wherein the yellow light can represent the light absorption efficiency below 33%, and the orange light can represent the light absorption efficiency at 33%. And between 67%, and red light can represent a light absorption efficiency of more than 67%.

The solar panel 10 in FIG. 3A is not positively incident with respect to the incident light L. At this time, the light absorption efficiency of the solar panel 10 is low (assuming less than 33%), so the control unit 11 can control the first indicating device 12 and the second. The indicating device 13 emits yellow light to alert the user.

In order to maximize the light absorption efficiency, the user may first rotate the first base 14 until the second indicating device 13 emits red light, and then rotate the solar module 15 until the first indicating device 12 emits red light, as shown in FIG. 3B. . At this time, the incident light L is incident on the solar panel 10 in the forward direction, so that the solar panel 10 has an optimum output power.
