When describing each component, each of the first frame 101 and the second frame 103 is formed to be inclined to the ground. For example, each of the first frame 101 and the second frame 103 may be formed in a shape similar to the letter "A". Each of the first frame 101 and the second frame 103 may be coupled to a plurality of second horizontal axes 105 to a part of the frame.

Each of the plurality of horizontal axes 105 forms a plurality of stages to connect the first frame 101 and the second frame 103. Here, each of the plurality of horizontal axes 105 may be spaced apart at a predetermined interval.

Each of the plurality of solar cell modules 110 converts solar energy into electrical energy. Each of the plurality of solar cell modules 110 may be disposed on the plurality of horizontal axes 105 to absorb sunlight. Here, each of the plurality of solar cell modules 110 may be formed by forming an array of solar cells that convert solar energy into electrical energy.

Each of the plurality of first sleeves 120 supports the plurality of solar cell modules 110. Here, each of the plurality of first sleeves 120 may be disposed between each of the plurality of horizontal shafts 105 and the plurality of solar cell modules 110.

In this case, each of the plurality of first sleeves 120 may include a sleeve lower guide surface 125 for reciprocating movement.

Each of the plurality of second sleeves 130 supports the plurality of first sleeves 120. Here, each of the plurality of second sleeves 130 may be coupled to each of the plurality of horizontal shafts 105. Each of the plurality of second sleeves 130 may be disposed under the plurality of first sleeves 120. Each of the plurality of second sleeves 130 may be formed in an area corresponding to the plurality of first sleeves 120.

The plurality of reciprocating motion controllers 140 will be described in more detail with reference to FIGS. 4 and 5.

4 and 5 are diagrams illustrating movement distance adjustment of a reciprocating movement control unit according to an embodiment of the present invention.

Each of the plurality of reciprocating motion controllers 140 reciprocates the plurality of first sleeves 120. Here, each of the plurality of reciprocating movement controllers 140 may move the plurality of first sleeves 120 so that the plurality of solar cell modules 110 arranged in multiple stages are not affected by shadows. In this case, each of the plurality of reciprocating movement control unit 140 may be configured as a device for converting the rotational movement to linear movement for the movement of the plurality of first sleeve (120). For example, each of the plurality of reciprocating movement controllers 140 may move the plurality of first sleeves 120 by embedding a worm, a worm wheel, or a motor therein. Each of the plurality of reciprocating movement controllers 140 may be installed on the bottom surface of the plurality of second sleeves 130. The plurality of reciprocating movement controllers 140 may control the separation distance between the upper solar cell module 110 and the lower solar cell module 110 to remove the shadow effect.

2 and 3, each of the plurality of first rods 190 transmits an external force to the plurality of second sleeves 130. Here, each of the plurality of first rods 190 may be installed under the plurality of second sleeves 130. For example, each of the plurality of first rods 190 may be installed in close contact with the bottom surfaces of the plurality of second sleeves 130 and may be coupled to the second rod 195.

The second rod 195 transmits an external force to the plurality of first rods 190. Here, the second rod 195 may be disposed along one side frame of the first frame 101 and connected to the plurality of first rods 190. The second rod 195 may be disposed adjacent to the plurality of second sleeves 130. In this case, the second rod 195 may be connected to the rotation angle controller 197.

The second rod 195 is reciprocated in the longitudinal direction by the rotation angle control unit 197. As a result, the second rod 195 may move the plurality of coupled first rods 190 in the longitudinal direction. In addition, the second rod 195 may rotate the plurality of second sleeves 130 through the movement of the plurality of first rods 190.

The rotation angle control unit 197 will be described in more detail with reference to FIGS. 6 and 7.

6 and 7 are diagrams showing the rotation angle adjustment of the rotation angle control unit according to an embodiment of the present invention.

The rotation angle controller 197 adjusts the movement of the second rod 195. The rotation angle controller 197 may be coupled to the first frame 101 and connected to the second rod 195. The rotation angle controller 197 may move a second rod 195 in the longitudinal direction of the second rod 195 by having a worm or a worm wheel therein and a motor coupled to the power source. For example, the rotation angle controller 197 may gradually adjust the inclination angles of the plurality of second sleeves 130 by pulling down the second rod 195. On the contrary, the rotation angle controller 197 may gradually adjust the inclination angles of the plurality of second sleeves 130 by pushing the second rod 195 upward. Through this, the rotation angle controller 197 may adjust the rotation angles of the plurality of second sleeves 130. Accordingly, the rotation angle controller 197 may adjust the directing angles of the plurality of solar cell modules 110 such that sunlight is vertically incident on each of the plurality of solar cell modules 110. In addition, the rotation angle controller 197 may control the plurality of solar cell modules 110 to an optimal position by applying solar altitude according to time and season.

When the plurality of solar cell modules 110 are moved forward by the plurality of reciprocating movement controllers 140 and the rotation angle controller 197, the separation distance is increased by the length of the plurality of reciprocating movement controllers 140 and the rotation angle controller 197, thereby eliminating the shadow effect due to the multilayer. In addition, the plurality of solar cell modules 110 may be adjusted to be disposed at a predetermined inclination angle by the second rod 195 moving up and down by the rotation angle controller 197. Accordingly, since the plurality of solar cell modules 110 may be adjusted from about 10 degrees to about 60 degrees, which is an optimal inclination angle, the maximum amount of power generated may be maintained by the inclination angle having the largest incident amount according to season, month, and time.

The solar cell array device according to an embodiment of the present invention is mounted on a sleeve. By mounting the battery module and reciprocating linear movement of the solar cell module together with the sleeve to adjust the separation distance between the modules can solve the shadow problem affecting the amount of power generated. In addition, the solar cell array device according to an embodiment of the present invention can maximize the amount of photovoltaic power by rotating the solar cell module to optimally adjust the inclination angle. In addition, since the solar cell array device according to an embodiment of the present invention can increase the amount of power generated per unit area, a small empty lot or the like can be utilized as a solar power generation site.
