The solar cell module 6 according to the present embodiment is preferably assembled at the top of the modular smart street light so as to improve the light collecting efficiency.

The solar cell module 6 uses the shadow to track the altitude and azimuth of the sun and control the direction of the solar panel 10 to face perpendicular to the angle at which the sunlight is incident, thereby increasing the light collection efficiency. As shown in FIG. 4, the main configuration includes a light tracking unit 100, a driving unit 200, and a control unit 300.

First, the light tracking unit 100 is configured on the solar panel 10 and is configured on the principle of tracking the incident angle of sunlight using shadows generated by sunlight. Let's explain.

In addition, the driving unit 200 is connected to the solar panel 10 as shown in FIG. 4 to control the vertical angle and the left and right rotation of the solar panel 10.

At this time, the driving unit 200 is applicable to a variety of conventional techniques configured to control the angle of the solar panel 10 to various angles, such as up, down, left, and right, a detailed description thereof will be omitted.

Subsequently, the control unit 300 is connected to the light tracking unit 100 and the driving unit 200 as shown in FIG. It is configured to operate the driving unit 200 to face the vertically to adjust the angle of the solar panel (10).

Meanwhile, the light tracer 100 is disposed horizontally on the plane of the solar panel 10 as shown in FIGS. 5A to 5B, and is disposed at the center of the solar panel 10 as shown in FIG. 5A. Can be.

In this case, when the light tracking unit 100 is disposed at the center of the solar panel 10, a space may be generated in the light collecting module (not shown) as much as the area where the light tracking unit 100 is disposed, and thus the light collecting efficiency may be reduced. As shown in FIG. 5B, it may be configured to be disposed outside the solar panel 10.

Hereinafter, the light tracer 100 that is one configuration of the present invention will be described in more detail with reference to FIGS. 6 to 9.

First, the light tracking unit 100 according to the present invention is characterized in that it comprises a base plate 110, partition plate 120 and the sensing member 130 as shown in Figs. 6a and 6b.

The base plate 110 is installed parallel to the solar panel 10, as shown in FIG.

In addition, the partition plate 120 protrudes from the base plate 110, and the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124 are the same point. Are configured to extend in four directions from each other to form a 'twelve' shape, and as shown in FIGS. 6 to 7, the first plate 121, the second plate 122, and the third plate 123. And the quadrant is divided by the fourth plate 124 based on the center of the base plate 110.

That is, the base plate 110 is divided into a first quadrant (I), a second quadrant (II), a third quadrant (III), and a fourth quadrant (IV) by the partition plate 120.

In this case, as shown in FIG. 6A, the partition plate 120 may include a first plate 121, a second plate 122, a third plate 123, and a fourth plate 124 each having a right triangle shape. In some cases, as illustrated in FIG. 6B, the first plate 121, the second plate 122, the third plate 123, and the fourth plate 124 may be formed in a rectangular shape.

Subsequently, the sensing member 130 is configured on each of the quadrants partitioned by the partition plate 120, and the solar region and the solar light directly radiated to the partition plate 120 are applied to the partition plate 120. It is configured to separate and detect the shadow area S generated by being masked. In this case, an illumination sensor or the like may be applied to the sensing member 130.

By the above configuration, the light tracking unit 100 may detect a direction in which the sun moves based on the shadow generated by the partition unit, and the control unit 300 drives the driving unit 200 to sense the sensing member. By adjusting the angle of the photovoltaic panel 10 to minimize the shadow area S generated at 130, the photovoltaic panel 10 may be controlled to always maintain a perpendicular relationship to the incident angle of sunlight.

Looking at the mechanism of the light tracer 100 in more detail, in the state in which the light tracer 100 is arranged as shown in Figure 7 the solar incident angle is irradiated perpendicular to the light tracer 100 and the second quadrant When moving to the (II) side, the shadow is generated only in the first quadrant (I), the third quadrant (III), and the fourth quadrant (IV) as shown in the drawing, so that the sensing member 130 controls the sensing signal detected therein. By transmitting to 300, the control unit 300 drives the driving unit 200 to change the angle of the photovoltaic panel 10 to the second quadrant (II) side where no shadow is generated (arrow direction indicated on the upper left of the drawing). The solar light incident angle and the solar panel 10 can be maintained in a vertical relationship, thereby improving the light collecting efficiency of the solar panel 10.

At this time, the second quadrant (II) side corresponds to the range of 90 ° and 180 ° in the drawing, and if the sun moves in the θ1 direction in the drawing, the solar panel 10 is in the direction of the arrow shown in the upper left of the drawing corresponding thereto. If the angular displacement can be maintained a vertical relationship between the solar incident angle and the solar panel 10.

However, if the sun moves in the 90 ° and 180 ° ranges in the drawing in the direction of θ2 less than θ1 or θ3 greater than θ1, then the first quadrant (I), third quadrant (III) and fourth quadrant (IV) Since the shadow is generated on the surface of the photovoltaic panel, the angle between the photovoltaic panel 10 and the photovoltaic panel 10 is precisely adjusted by simply adjusting the angle of the photovoltaic panel 10 to the second quadrant (II) side (the direction of the arrow shown at the upper left of the drawing). You will not be able to maintain the vertical relationship.

In order to compensate for this problem, in the present invention, as shown in FIG. 8, a rotating part 140 for rotating the base plate 110 may be further provided on the light tracking part 100. The controller 300 may be configured to be controlled to rotate.

That is, the control unit 300 is out of the vertical relationship between the solar incident angle and the solar panel 10 as shown in FIG. 9A, so that the control unit 300 is divided into three of the first quadrant I through the fourth quadrant IV by the partition plate 120. When the shadows are generated in the four quadrants, the pivot unit 140 is controlled to rotate the base plate 110 in a clockwise or counterclockwise direction, so that the shadows are formed in the first quadrant (I) to the fourth as shown in FIG. 9B. As soon as only two quadrants of the quadrant IV are generated, the driving of the rotating unit 140 is stopped.

Subsequently, the control unit 300 controls the driving unit 200 as shown in FIG. 9B to display the photovoltaic panel 10 on the opposite side of the shadow area S generated in two quadrants (in the upper left of the drawing). By angular displacement in the direction of one arrow, the angular displacement of the solar panel 10 according to the positional displacement of the sun can be made precisely, that is, more accurate vertical relationship between the solar incident angle and the solar panel 10 can be achieved. It will be.

That is, as shown in FIG. 9B, when the shadow area S is generated only in the third quadrant III and the fourth quadrant IV, the controller 300 operates the driving unit 200 to shadow the solar panel 10. When displaced toward the second plate 122 side (arrow direction shown in the upper left of the drawing), which is the common opposite side of the region S, the shadow region S disappears in all quadrants at some point, and then the control unit 300 By stopping the operation of the driving unit 200 can be controlled to have a perfect vertical relationship between the solar light incident angle and the solar panel 10.

Meanwhile, as shown in FIG. 6A, the partition plate 120 is preferably configured in such a manner that the center is the highest and the height decreases toward each end, which is the same as in FIG. 7, 9, and 9B. If the angle of incidence is not perpendicular to the solar panel 10, the shadow is generated in the form of a larger area from the end of the partition plate 120, so that the sensing member 130 can more accurately recognize whether the shadow is generated. It will be.

That is, when sunlight is hidden by each plate to generate a shadow, the shadow member has a constant pattern in the form of a triangle gradually increasing from the end of the partition plate 120 as shown in the drawing, so the sensing member 130 is each quadrant This will make it easier to see if shadows are being generated.

In other words, as the altitude or azimuth of the sun changes and the angle of incidence of the solar light moves away from the vertical relationship with the solar panel 10, the shadow shape is maintained in a triangular shape, but the height and area of the sun are gradually increased. At 130, the distance of the sun can be estimated based on the height and area of the shadow, so that the solar panel 10 can have a more accurate data on the angular displacement to be progressed by the solar panel 10 to have a vertical relationship with the incident angle of the sun. It will be.

If the shape of the first plate 121 to the fourth plate 124 is formed in a general plate shape rather than a shape that is lowered toward the end as in this embodiment, the first quadrant (I) to the fourth quadrant (IV) ), The shape of the shadow is not formed uniformly and the shape of the shadow does not change regularly during the movement of the sun, so the sensing member 130 can detect the presence or absence of shadows for each quadrant, so that the movement distance of the sun can be accurately determined. It becomes untraceable.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of right.
