[0014] Hereinafter, an embodiment of a floating solar cell structure according to the present invention will be described with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are easily replaceable by a person skilled in the art, or those that are substantially the same.

[0015] Fig. 1 is a perspective view that shows a schematic example of a floating solar cell structure 100 according to this embodiment. As shown in Fig. 1, the floating solar cell structure 100 includes a solar cell panel 10 and a support 20. The solar cell panel 10 and the support 20 are formed in a state of extending in one direction. In the following, in describing the configuration of the solar cell panel 10 and the support 20, the one direction in which the solar cell panel 10 and the support 20 extend is referred to as an extension direction D1, and the direction perpendicular to the extension direction D1 is referred to as a width direction D2.

[0016] The solar cell panel 10 is formed in a flexible state. The solar cell panel 10 has a light receiving area 13 on a first surface 11.

[0017] The support 20 is bag-shaped. The support 20 is formed to have flexibility using a soft resin material such as synthetic rubber. The support 20 supports the second surface 12 on the back side of the first surface 11 of the solar cell panel 10. The support 20 can adjust the amount of gas such as air inside. The support 20 changes its outer shape by adjusting the amount of gas inside. As the gas, various gases such as air and nitrogen gas can be used. The support 20 is formed so that it floats on water together with the solar cell panel 10 with gas inside. The support 20 is formed so that the end 20a side expands more in the vertical direction than the end 20b side by introducing gas.

[0018] 2 is a diagram showing an example of a floating solar cell structure 100 floating on water. The support 20 is formed so that a support surface 21 supporting the solar cell panel 10 is inclined downward with respect to the horizontal plane from one end 20a to the other end 20b in the width direction D2 when the support 20 is filled with gas and floated on water. In this case, the support 20 can support the solar cell panel 10 so that the support surface 21 is inclined downward with respect to the horizontal plane from the end 20a side to the end 20b side.

[0019] The support 20 can adjust the amount of gas inside to adjust the inclination of the solar cell panel 10 relative to the horizontal plane when floating on water. With this configuration, the inclination of the solar cell panel 10 can be appropriately adjusted according to the installation position of the floating solar cell structure. Therefore, the solar cell panel 10 can be used efficiently.

[0020] The support 20 has a partition member 22 therein. The partition member 22 divides the inside into a plurality of spaces K. The support 20 can adjust the amount of gas for each space K. The partition members 22 are arranged so that the spaces K are aligned along the tilt direction of the solar cell panel 10. That is, the partition members 22 are arranged so that the spaces K are aligned in the width direction D2. One or more partition members 22 can be provided in the width direction D2. The partition members 22 may be arranged so that the volumes of the spaces K are the same, or so that the cross-sectional areas of the spaces K (cross-sectional areas of the cross sections taken along a plane perpendicular to the extension direction D1) are the same, or they may be arranged in a different manner.

[0021] The partition member 22 is provided, for example, from one end 20c to the other end 20d in the extension direction D1. By partitioning the inside of the support 20 in this manner, for example, the amount of gas is gradually reduced from the space K on the end 20a side to the space K on the end 20b side in the width direction D2, and the support surface 21 can be easily inclined.

[0022] The support 20 has a lift-up prevention mechanism 30 at the end 20a and the end 20b. The lift-up prevention mechanism 30 may be configured to be disposed at least one of the end 20a and the end 20b. In other words, the lift-up prevention mechanism 30 may be disposed at only one of the end 20a and the end 20b.

[0023] Fig. 3 is a diagram showing an example of the lifting prevention mechanism 30. As shown in Fig. 3, the lifting prevention mechanism 30 may have a configuration including, for example, a film-like member 31 suspended from the ends 20a and 20b of the support 20 (see Fig. 3(A)).

[0024] The lift-up prevention mechanism 30 may also be configured to have a bag-shaped member 32 arranged on the bottom surface 23 of the support 20 (see FIG. 3(B)). In this case, the bag-shaped member 32 may be configured to be flexible.

[0025] Furthermore, when the lift-up prevention mechanism 30 has a film-like or plate-like member 31, it may be attached to the ends 20a, 20b via hinges 33 (see FIG. 3(C)).

[0026] The lift-up prevention mechanism 30 may have a different weight on the end 20a side from that on the end 20b side. The lift-up prevention mechanism 30 may be set so that the weight on the end 20b side is heavier than the weight on the end 20a side. In this case, the support surface 21 of the support body 20 can be formed to have a downward inclination from the end 20a side to the end 20b side.

[0027] 4 to 6 are diagrams showing an example of a usage state of the floating solar cell structure 100. As shown in Fig. 4, by removing the gas from inside the support 20, the floating solar cell structure 100 can roll up the solar cell panel 10 and the support 20 as a unit. Specifically, by removing the gas from inside the support 20, the support 20 is collapsed in the vertical direction, that is, the partition member 22 is bent, and the insides of the support surface 21 and the bottom surface 23 are in contact with each other.

[0028] The support body 20 is formed so that it can be rolled up integrally with the solar cell panel 10 in a state where the internal gas has been removed. Since both the solar cell panel 10 and the support body 20 are flexible, from this state, the solar cell panel 10, the support body 20, and the lift-off prevention mechanism 30 can be rolled up integrally from one side of the end portion 20c and the end portion 20d in the extension direction D1 to the other side, for example, as shown in Fig. 5 .

[0029] As shown in Fig. 5, the floating prevention mechanism 30 is integrally rolled up to roll up the floating solar cell structure 100. By rolling up the floating solar cell structure 100, it becomes compact in the extension direction D1, making it easier to transport. Note that Fig. 5 shows an example in which the floating prevention mechanism 30 is in the form of a film, but the present invention is not limited to this configuration.

[0030] Furthermore, the floating solar cell structure 100 can be submerged in water with the solar cell panel 10 and the support 20 as a unit after the gas inside the support 20 has been removed. For example, the solar cell panel 10, the support 20, and the floating prevention mechanism 30 are formed so that their total weight exceeds the buoyancy. As a result, by removing the air from the support 20, the floating solar cell structure 100 can be submerged in water under its own weight, as shown in FIG. 6.

[0031] In this case, the floating solar cell structure 100 can be made to float on water again by injecting gas into the inside of the support 20 from a submerged state, for example, via a hose from land.

[0032] As described above, the floating solar cell structure 100 of this embodiment is formed in a flexible state and comprises a solar cell panel 10 having a light receiving area 13 on a first surface 11, and a bag-shaped support body 20 supporting a second surface 12 behind the first surface 11 of the solar cell panel 10, the support body 20 being capable of adjusting the amount of internal gas and being formed so as to float on water together with the solar cell panel 10 when gas is placed inside, and being capable of adjusting the inclination of the solar cell panel 10 relative to the horizontal plane when floating on water by adjusting the amount of internal gas, and being formed so as to be rolled up together with the solar cell panel 10 when the internal gas is released.

[0033] According to this configuration, the bag-shaped support 20 supporting the solar cell panel 10 can adjust the amount of gas inside, and floats on water together with the solar cell panel 10 when air is filled inside, and the inclination of the solar cell panel 10 relative to the horizontal plane when floating on water can be adjusted by adjusting the amount of gas inside, so that the solar cell panel 10 can be appropriately inclined according to the installation position of the floating solar cell structure. In addition, the support 20 is formed so as to be rolled up integrally with the solar cell panel 10 when the gas inside is removed, so that the configuration is easy to transport. This makes it possible to provide a floating solar cell structure 100 that can be floated on water and easily moved, such as removed or evacuated.

[0034] In the floating solar cell structure 100 according to this embodiment, the support body 20 is formed so as to be submerged in water together with the solar cell panel 10 with the internal gas removed.

[0035] According to this configuration, by submerging the support 20 together with the solar cell panel 10 in water after removing the gas from inside, the floating solar cell structure 100 can be retreated below the water surface during bad weather, etc. When the weather improves, gas can be introduced into the support 20, allowing it to float on the water again.

[0036] In the floating solar cell structure 100 according to this embodiment, the support body 20 has partition members 22 that divide the inside into a plurality of spaces K, and the amount of gas in each space K can be adjusted.

[0037] According to this configuration, by adjusting the amount of gas for each space K, the shape of the support 20 can be appropriately adjusted.

[0038] In the floating solar cell structure 100 according to this embodiment, the partition members 22 are arranged so that the spaces K are aligned along the tilt direction of the solar cell panel 10.

[0039] According to this configuration, by adjusting the amount of gas for each space K, the inclination of the solar cell panel 10 can be appropriately adjusted.

[0040] In the floating solar cell structure 100 of this embodiment, the solar cell panel 10 and the support 20 are formed in a state extending in one direction, and the support 20 supports the solar cell panel 10 so that it is inclined from one end to the other end in the width direction perpendicular to the one direction.

[0041] According to this configuration, by tilting the solar cell panel 10 in the width direction, which is the short side direction, the solar cell panel 10 can be tilted efficiently.

[0042] In the floating solar cell structure 100 according to this embodiment, the support body 20 has a floating prevention mechanism 30 at least on one end and the other end in the width direction perpendicular to the one direction.

[0043] According to this configuration, the floating prevention mechanism 30 is disposed at least at one end and the other end of the width direction of the support 20 perpendicular to one direction, so that the support 20 can be prevented from floating up due to wind, etc. Also, because the ends 20a, 20b are not exposed to the water surface, air is less likely to enter the underside of the support 20, and the generation of unexpected upward forces can be prevented. This improves the degree of contact between the support 20 and the water surface, and prevents the solar cell panel 10 from capsizing.

[0044] The technical scope of the present invention is not limited to the above-described embodiment, and appropriate modifications can be made without departing from the spirit of the present invention. [Explanation of symbols]
