Hereinafter, embodiments will be described with reference to the drawings. In the drawings attached to the present specification, the scale, aspect ratio, etc. are appropriately changed from those of the actual product and exaggerated for the convenience of illustration and comprehension. In addition, as used in the present specification, the terms such as "parallel", "orthogonal", and "same" and the values of length and angle that specify the shape and geometric conditions and their degrees are strictly used. Without being bound by meaning, we will interpret it including the range in which similar functions can be expected.

1 to 9 are diagrams for explaining one embodiment. Of these, FIGS. 1 and 2 are perspective views or vertical sectional views showing the configuration of the solar cell composite display body 10, and FIGS. 3 to 5 are views for explaining the operation of the solar cell composite display body 10. 6 to 8 are views for explaining an example of a method for manufacturing the solar cell composite display body 10, and FIG. 9 is a view for explaining the frame member 70.

The solar cell composite display body 10 described here exhibits both a predetermined display function and a power generation function using external light. In the solar cell composite display body 10 shown in FIGS. 1 and 2, a plurality of orientation adjusting surfaces 21 and a plurality of light transmitting surfaces 22 alternately arranged in the first axial direction d1 receive light more than the solar cell panel 50. It is provided on the side. When the solar cell composite display body 10 is observed from the direction D21 within a certain angle range AR1, the display surface 12 arranged mainly on the orientation adjustment surface 21 is observed. Therefore, the display surface 12 exerts a display function for an observer who observes the solar cell composite display body 10 from a certain angle range AR1. On the other hand, the light L22 incident from a direction within another certain angle range AR2 mainly passes through the light transmitting surface 22 and is guided to the solar cell panel 50. Therefore, the solar cell panel 50 exerts a power generation function with respect to the light incident on the solar cell composite display body 10 from another certain angle range AR2. Therefore, according to the solar cell composite display body 10, when the observer observes the display surface 12, the solar cell panel 50 makes use of the difference between the observation direction from the observer and the incident direction of the external light. It suppresses the visibility and makes it possible to harmonize with the surroundings.

Hereinafter, the configuration and operation / effect of the solar cell composite display body 10 according to the present embodiment will be described in detail. As is well shown in FIGS. 1 and 2, the solar cell composite display body 10 includes a sheet-shaped sheet member 20, a solar cell panel 50 arranged on the back surface of the sheet member 20, and at least a solar cell panel. It includes a frame member 70 that holds 50. The frame member 70 will be described later with reference to FIG.

The sheet-shaped sheet member 20 has a first surface 20a and a second surface 20b as a pair of main surfaces facing each other. The first surface 20a forms an incident surface such as external light such as sunlight incident on the solar cell composite display body 10. Further, the first surface 20a forms an exit surface from which the light from the display surface 12 that visualizes the display target 13 (see FIG. 3) is emitted from the solar cell composite display body 10. On the other hand, the second surface 20b forms a surface facing the solar cell panel 50.

The second surface 20b of the sheet member 20 includes a plurality of orientation adjusting surfaces 21 and a plurality of light transmitting surfaces 22 alternately arranged in the first axial direction d1. A display surface 12 for displaying the display target 13 is arranged on the orientation adjustment surface 21. The orientation adjusting surface 21 is provided to support the display surface 12 and adjust the viewing angle at which the display surface 12 can be observed. On the other hand, the light transmitting surface 22 is provided to transmit the light L22 incident on the solar cell composite display body 10 between the adjacent display surfaces 12 and guide the light L22 to the solar cell panel 50. In the illustrated example, the plurality of orientation adjusting surfaces 21 are configured to be the same as each other, and the plurality of light transmitting surfaces 22 are also configured to be the same as each other.

In this specification, terms such as "sheet", "film", and "board" are not distinguished from each other based only on the difference in names. Therefore, for example, "sheet" is a concept that includes a member that can also be called a film or a plate.

Further, in the present specification, the "sheet surface (film surface, plate surface, panel surface)" is the plane of the target sheet-like member when the target sheet-like member is viewed as a whole and in a broad sense. Refers to the plane that coincides with the direction. In the embodiment described below, the seat surface of the seat member 20, the panel surface of the solar cell panel 50, and the light receiving surface 50a of the solar cell panel 50 are parallel to each other. Further, in the present specification, the "normal direction" used for a sheet-shaped (film-shaped, plate-shaped, panel-shaped) member refers to the normal direction of the member to the sheet surface.

As shown in FIG. 1, each orientation adjusting surface 21 and each light transmitting surface 22 extend linearly in a direction intersecting the first axial direction d1 which is the arrangement direction thereof. In particular, in the illustrated example, each orientation adjusting surface 21 and each light transmitting surface 22 extend linearly in the second axial direction d2 orthogonal to both the first axial direction d1 and the normal direction nd of the seat member 20. ing. Further, in the example shown in FIG. 2, each orientation adjusting surface 21 and each light transmitting surface 22 are arranged so as to be offset from each other when viewed from the normal direction nd. In the present embodiment, the first axial direction d1 and the second axial direction d2 are along the seat surface of the seat member 20 and orthogonal to the normal direction nd of the seat member 20. In the illustrated example, the solar cell composite display body 10 is arranged so that the first axial direction d1 is parallel to the vertical direction and the second axial direction d2 is parallel to the horizontal direction.

Each orientation adjusting surface 21 is inclined with respect to the seat surface of the seat member 20, in other words, the panel surface of the solar cell panel 50, and is also inclined with respect to the normal direction nd of the seat member 20. That is, each orientation adjusting surface 21 is non-parallel to both the seat surface of the seat member 20 and the normal direction nd of the seat member 20. By inclining the display surface 12 arranged on the orientation adjustment surface 21 together with the orientation adjustment surface 21 with respect to the panel surface of the solar cell panel 50, a viewing angle capable of observing the display target 13 provided on the display surface 12 The first angle range AR1 can be adjusted with a high degree of freedom.

As shown in FIG. 2, one end portion 21a of each orientation adjusting surface 21 located on one side (upper side in FIG. 2 and upper side in the vertical direction) in the first axial direction d1 has a one end portion 21a in the first axial direction d1. The seat member 20 is separated from the solar panel 50 in the normal direction nd of the seat member 20 from the other end 21b located on the other side (lower side in FIG. 2 and lower side in the vertical direction). It is inclined with respect to the seat surface of. As can be understood from FIG. 2, according to such an orientation adjusting surface 21, light is easily emitted toward an angle range inclined to the other side with respect to the normal direction nd. That is, the display function from the display surface 12 arranged on the orientation adjustment surface 21 is effectively exerted when observed from the direction D21 inclined to the other side with respect to the normal direction nd.

The display surface 12 is arranged along the orientation adjustment surface 21 so as to overlap the orientation adjustment surface 21. Therefore, in the display surface 12 arranged on the orientation adjusting surface 21, one end portion 12a located on one side in the first axial direction d1 is a sheet more than the other end portion 12b located on the other side in the first axial direction d1. The seat member 20 is inclined with respect to the seat surface so as to be separated from the solar cell panel 50 in the normal direction nd of the member 20.

The light emitted from the solar cell composite display body 10 from the display surface 12 toward the first angle range AR1 visualizes the display target 13 given to the display surface 12. That is, the display surface 12 is visually recognized from the first angle range AR1, and as a result, the display target 13 formed on the display surface 12 can be observed. When displaying the display target 13 moved by the display surface 12, it is convenient to use the electricity generated from the solar cell panel 50 for driving.

FIG. 3 shows an example of the display target 13 formed on the display surface 12. A plurality of display surfaces 12 are arranged in the first axial direction d1, and each display surface 12 extends linearly in the second axial direction d2 orthogonal to the first axial direction d1. Therefore, the display surface 12 located at each position in the first axial direction d1 is given the display target element 13a corresponding to the position of the display surface 12 in the first axial direction d1, so that the display surface 12 is in the second axial direction d2. It is possible to display the two-dimensional display target 13 as a combination of the display target elements 13a formed on each elongated display surface 12. In the example shown in FIG. 3, the capital letter "N" of the alphabet is displayed as the display target 13. By displaying the display target 13 as a combination of the plurality of display target elements 13a in this way, the size of each orientation adjustment surface 21 can be reduced, so that the first angle range AR1 can be widened or the solar cell composite display body 10 can be used. Even if the size is increased, a better display target 13 can be observed.

As described above, in the solar cell composite display body 10 of the present embodiment, the angle range in which the display target 13 is continuously displayed can be adjusted with a high degree of freedom. Therefore, the solar cell composite display body 10 of the present embodiment can be used for various purposes, for example, a size of several meters to several tens of meters used for an outdoor signboard, a road information bulletin board, an outer wall surface of a building, or the like. Large panel applications, medium-sized panels with a size of several tens of centimeters to several meters used for posters, signs, inner walls of buildings, etc., and small panels with a size of several centimeters to several tens of centimeters used for desktop stands, mobile terminals, etc. Applications and the like can be exemplified.

On the other hand, each light transmitting surface 22 located between the adjacent orientation adjusting surfaces 21 is inclined with respect to the seat surface of the sheet member 20, in other words, the panel surface of the solar cell panel 50, and is in the normal direction of the sheet member 20. It is also inclined with respect to nd. That is, each orientation adjusting surface 21 is non-parallel to both the seat surface of the seat member 20 and the normal direction nd of the seat member 20. By inclining the light transmitting surface 22 with respect to the panel surface of the solar cell panel 50, the second angle range AR2, which is an angle range in which power generation by the solar cell panel 50 can be continuously and stably performed, is set high. It can be adjusted with a degree of freedom.

The angle at which the light transmitting surface 22 is inclined with respect to the seat surface of the sheet member 20 is different from the angle at which the orientation adjusting surface 21 is inclined with respect to the seat surface of the light control sheet 20. In particular, in the main cross section of the solar cell composite display shown in FIG. 2, the light transmitting surface 22 is inclined to the side opposite to the orientation adjusting surface 21 with respect to the normal direction nd of the sheet member 20. As described above, each orientation adjusting surface 21 is provided with respect to the seat surface of the seat member 20 so that the one end 21a is separated from the solar cell panel 50 in the normal direction nd of the seat member 20 with respect to the other end 21b. It is inclined. Therefore, in each light transmitting surface 22, the other end 22b located on the other side in the first axial direction d1 is in the normal direction of the sheet member 20 with respect to the one end 22a located on one side in the first axial direction d1. It is inclined with respect to the seat surface of the seat member 20 so as to be separated from the solar cell panel 50 at the nd. As can be understood from FIG. 2, such a light transmitting surface 22 is likely to receive light from an angle range inclined to one side with respect to the normal direction nd. Therefore, the light L22 incident on the solar cell composite display body 10 from a direction inclined to one side with respect to the normal direction nd can be easily guided by the solar cell panel 50.

Next, the relationship between the orientation adjusting surface 21 and the light transmitting surface 22 will be described. In the main cross section of the solar cell composite display shown in FIG. 2, the orientation adjusting surface 21 and the light transmitting surface 22 adjacent to the orientation adjusting surface 21 on the other side in the first axial direction d1 are in the first axial direction d1. The interval dt along the line becomes narrower stepwise or continuously as it approaches the solar cell panel 50 in the normal direction nd of the seat member 20. Therefore, the other end 21b of the orientation adjusting surface 21 is closest to the one end 22a of the light transmitting surface 22 located on the other side. In the illustrated embodiment, the other end 21b of the orientation adjusting surface 21 is connected to one end 22a of the light transmitting surface 22 located on the other side. However, the other end 21b of the orientation adjusting surface 21 may be separated from the one end 22a of the light transmitting surface 22 located on the other side.

On the other hand, one end 21a of the orientation adjusting surface 21 is connected to the other end 22b of the light transmitting surface 22 adjacent to the orientation adjusting surface 21 on one side in the first axial direction d1. However, one end 21a of the orientation adjusting surface 21 may be separated from the other end 22b of the light transmitting surface 22 adjacent to the orientation adjusting surface 21 on one side in the first axial direction d1.

Further, in the main cut surface shown in FIG. 2, the orientation adjusting surface 21 has the same length as the light transmitting surface 22 adjacent to the orientation adjusting surface 21. Therefore, the ratio of the orientation adjusting surface 21 to the second surface 20b of the sheet member 20 is equal to the ratio of the light transmitting surface 22 to the second surface 20b of the sheet member 20. However, in the main cut surface shown in FIG. 2, the orientation adjusting surface 21 may be different from the length of the light transmitting surface 22 adjacent to the orientation adjusting surface 21. In particular, when the orientation adjusting surface 21 is shorter than the light transmitting surface 22 adjacent to the orientation adjusting surface 21, the ratio of the orientation adjusting surface 21 to the second surface 20b of the sheet member 20 is set to the number of the sheet member 20. It can be made smaller than the ratio of the light transmitting surface 22 to the two surfaces 20b. In this case, it tends to be easy to guide a relatively large amount of light to the light transmitting surface 22, and as a result, it can contribute to guiding more light to the solar cell panel 50.

Further, in the example shown in FIG. 2, the angle θ1 formed by the orientation adjusting surface 21 with respect to the seat surface of the seat member 20 is equal to the angle θ2 formed by the light transmitting surface 22 with respect to the seat surface of the seat member 20. However, the angle θ1 formed by the orientation adjusting surface 21 with respect to the sheet surface of the sheet member 20 is determined according to the observation direction by the observer intended to be observed, and the light transmitting surface 22 is the sheet of the sheet member 20. The angle θ2 formed with respect to the surface is determined according to the incident direction of the external light intended to be captured. Therefore, the angle θ1 formed by the orientation adjusting surface 21 with respect to the seat surface of the seat member 20 may be different from the angle θ2 formed by the light transmitting surface 22 with respect to the seat surface of the seat member 20.

Further, in the example shown in FIG. 2, each orientation adjusting surface 21 and each light transmitting surface 22 are made of a flat surface. However, the present invention is not limited to such an example, and each orientation adjusting surface 21 and each light transmitting surface 22 may be formed of a curved surface. As an example, each orientation adjusting surface 21 and each light transmitting surface 22 may form a part of a spherical surface or a curved surface such as a lens surface. More specifically, each orientation adjusting surface 21 and each light transmitting surface 22 may be a lens surface curved so as to be convex toward the outer side, or may be concave toward the inward side. The lens surface may be curved as described above.

Similarly, in the example shown in FIG. 2, the display surface 12 is made of a flat surface. However, the present invention is not limited to such an example, and the display surface 12 may be formed of a curved surface. As an example, each display surface 12 may form a part of a spherical surface or a curved surface such as a lens surface. More specifically, each display surface 12 may be a lens surface curved so as to be convex toward the outer side, or a lens surface curved so as to be concave toward the inward side. There may be. In the present specification, when the display surface 12 is composed of a curved surface, "the display surface 12 is inclined with respect to a plane" means a straight line connecting both ends 12a and 12b of the display surface 12 on the main cut surface shown in FIG. Means that is tilted with respect to the plane.

Further, an air layer 30 is formed between the second surface 20b of the sheet member 20 and the solar cell panel 50. In the example shown in FIG. 2, the air layer 30 is formed between the second surface 20b of the sheet member 20 and the light receiving surface 50a of the solar cell panel 50. The sheet member 20 is not limited to the example in which the sheet member 20 is arranged via the solar cell panel 50 and the air layer 30, and may be joined to the solar cell panel 50 via a bonding layer.

The solar cell panel 50 has a light receiving surface 50a facing the second surface 20b of the sheet member 20, a back surface 50b facing the light receiving surface 50a, and a side surface 50c extending between the light receiving surface 50a and the back surface 50b. ing. The solar cell panel 50 is a power generation device that converts the light received by the light receiving surface 50a into electrical energy. The light L22 taken into the light transmitting surface 22 is guided from the second angle range AR2 to the light receiving surface 50a of the solar cell panel 50, and this light L22 is used for power generation.

As shown in FIG. 1, the side surface 50c of the solar cell panel 50 includes a pair of upper side surfaces 50d and a lower side surface 50e facing the first axial direction d1, and a pair of lateral side surfaces 50f facing the second axial direction d2. Includes. Each of the surfaces 50d to 50f constituting the side surface 50c is configured as a flat surface.

As such a solar cell panel 50, various forms can be used. For example, a silicon-based solar cell panel including a flat plate-shaped silicon substrate made of single crystal silicon, polycrystalline silicon, or the like, a thin-film solar cell panel, a calcopyrite-based solar cell, or the like can be used as the solar cell panel 50.

Next, an example of the method for manufacturing the solar cell composite display body 10 described above will be described mainly with reference to FIGS. 6 to 8.

First, as shown in FIG. 6, the sheet member 20 is manufactured by molding a transparent resin. For molding, hot melt extrusion processing, injection molding, or the like can be adopted. As shown in FIG. 6, a plurality of orientation adjusting surfaces 21 and a plurality of light transmitting surfaces 22 are alternately formed on the second surface 20b of the obtained sheet member 20.

Next, as shown in FIG. 7, a display surface 12 is formed on the orientation adjusting surface 21 of the seat member 20. As an example, the display surface 12 is formed on the orientation adjusting surface 21 of the sheet member 20 by inkjet printing. After that, as shown in FIG. 8, the solar cell panel 50 is arranged so as to face the second surface 20b of the seat member 20. As a result, the solar cell composite display body 10 is obtained.

Next, the operation of the solar cell composite display body 10 will be described mainly with reference to FIGS. 4 and 5. The solar cell composite display body 10 is arranged so that, for example, the first axial direction d1, which is the arrangement direction of the orientation adjusting surface 21 and the light transmitting surface 22, is along the vertical direction. Specifically, the solar cell composite display body 10 is arranged so that one side in the first axial direction d1 is along the upper side in the vertical direction and the other side in the first axial direction d1 is along the lower side in the vertical direction. To.

As is well shown in FIG. 4, the display surface 12 arranged on the inclined orientation adjusting surface 21 is easily visible from the front direction of the display surface 12. In the example shown in FIG. 4, since the display surface 12 is inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, the first axial direction d1 with respect to the normal direction nd. When the solar cell composite display body 10 is observed from the directions D41, D42, and D43 inclined to the other side in the above, the display surface 12 becomes easy to see. By inclining the orientation adjusting surface 21 with respect to the normal direction nd of the sheet member 20 in this way, the first angle range AR1 which is the viewing angle at which the display surface 12 located on the orientation adjusting surface 21 is observed is determined. It can be adjusted with a high degree of freedom. Therefore, the observer can observe the display target 13 with excellent visibility and can display the display target 13 with excellent design.

On the other hand, the light transmitting surface 22 inclined at an angle different from the orientation adjusting surface 21 efficiently transmits the light L51, L52, L53 incident from a direction different from the directions D41, D42, and D43 where the orientation adjusting surface 21 is easily visible. It becomes possible to capture. In the example shown in FIG. 5, since the light transmitting surface 22 is inclined to the other side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, the first axial direction with respect to the normal direction nd. It is possible to efficiently capture the lights L51, L52, and L53 incident on the solar cell composite display body 10 from the direction inclined to one side in d1. The lights L51, L52, and L53 taken into the light transmitting surface 22 travel in the air layer 30 and are guided to the solar cell panel 50. In this way, by inclining the light transmitting surface 22 with respect to the normal direction nd of the sheet member 20 at an angle different from the orientation adjusting surface 21, the solar cell composite display body is guided to the solar cell panel 50. The second angle range AR2, which is the angle range in the direction of incidence on 10, can be adjusted with a high degree of freedom. Therefore, the solar cell composite display body 10 according to the present embodiment can efficiently receive sunlight whose incident direction changes according to the time zone and the season and use it for power generation in the solar cell panel 50. It will be possible.

As described above, according to the present embodiment, the seat member 20 having the first surface 20a and the second surface 20b facing the first surface 20a is arranged so as to face the second surface 20b of the sheet member 20. A plurality of display surfaces 12 each of which are inclined with respect to the panel surface of the solar cell panel 50 are arranged along the uniaxial direction d1 on the seat member 20. According to such a solar cell composite display body 10, since the display surface 12 is inclined with respect to the panel surface of the solar cell panel 50, the directions D21, D41 to the inclined display surface 12 are in the front direction thereof. It becomes easier to observe from D43. On the other hand, the luminous fluxes L23 and L51 to L53 incident on the solar cell composite display body 10 from a direction different from the directions D21 and D41 to D43 that make it easy to visually recognize the display surface 12 are between two adjacent display surfaces 12. It penetrates and is guided to the solar cell panel 50. In this way, by utilizing the difference between the observation directions D21, D41 to D43 from the observer and the incident directions of the external lights L23, L51 to L53, harmony with the surrounding environment is achieved, and the display on the display surface 12 and the display It is possible to effectively achieve both power generation by the solar cell panel 50. Moreover, since the solar cell panel 50 is arranged so as to face the second surface 20b of the sheet member 20, the light receiving surface 50a of the solar cell panel 50 is not exposed to the outside. Therefore, the solar cell panel 50 can be made more inconspicuous.

Further, according to the present embodiment, the second surface 20b of the sheet member 20 includes a plurality of orientation adjusting surfaces 21 and a plurality of light transmitting surfaces 22 alternately arranged in the uniaxial direction d1, and the orientation adjusting surfaces. 21 is inclined with respect to the panel surface of the solar cell panel 50, and the light transmitting surface 22 is inclined with respect to the panel surface of the solar cell panel 50 at an angle different from the orientation adjusting surface 21 and displayed on the orientation adjusting surface 21. The surface 12 is arranged. According to such a form, since the orientation adjusting surface 21 and the light transmitting surface 22 are inclined with respect to the panel surface of the solar cell panel 50, the inclined orientation adjusting surface 21 and the light transmitting surface 22 are in front of each other. It becomes easy to effectively use the light incident from the direction. In particular, the light transmitting surface 22 is inclined with respect to the panel surface of the solar cell panel 50 at an angle different from that of the orientation adjusting surface 21. Therefore, the display surface 12 arranged on the orientation adjusting surface 21 is a solar cell composite display body from directions D21, D41 to D43 different from the inclined direction of the light L22, L51 to L53, which are easily taken in by the light transmitting surface 22. Light L22, L51 that is easily visible when observing 10 and the light transmitting surface 22 is incident on the solar cell composite display body 10 from a direction different from the directions D21 and D41 to D43 that make it easy to see the orientation adjusting surface 21. ~ L53 is effectively taken in. As a result, it is possible to effectively achieve both the display on the display surface 12 and the power generation by the solar cell panel 50.

By the way, when observing the display object 13 formed on the display surface 12 arranged on the orientation adjusting surface 21, when the solar cell panel 50 is observed together with the display object 13 through the light transmitting surface 22, the solar cell panel 50 is observed. This will significantly impair the visibility and design of the display target 13. Therefore, it is preferable that the first angle range AR1 in which the display surface 12 can be observed is separated from the second angle range AR2 in which the solar cell panel 50 is observed, that is, it does not overlap.

Therefore, in the solar cell composite display body 10 of the present embodiment, in the main cutting surface shown in FIG. 2, the orientation adjusting surface 21 is on the opposite side of the light transmitting surface 22 with respect to the normal direction nd of the sheet member 20. It is inclined to. According to such a form, the display surface 12 arranged on the orientation adjusting surface 21 is from the directions D21 and D41 to D43 opposite to the inclined direction of the light L22 and L51 to L53 which are easily taken in by the light transmitting surface 22. When observing the solar cell composite display body 10, it can be easily observed selectively, and the light transmitting surface 22 is the sun from a direction opposite to the directions D21 and D41 to D43 where the orientation adjusting surface 21 is easily visible. Lights L22 and L51 to L53 incident on the battery composite display body 10 can be selectively captured. Specifically, the orientation adjusting surface 21 is inclined with respect to the seat surface of the seat member 20 so that one end 21a is separated from the solar cell panel 50 in the normal direction nd of the seat member 20 with respect to the other end 21b. The light transmitting surface 22 is inclined with respect to the seat surface of the seat member 20 so that the other end 22b is separated from the solar cell panel 50 in the normal direction nd of the seat member 20 with respect to the one end 22a. .. In this case, when the solar cell composite display body 10 is observed from the directions D21 and D41 to D43 inclined to the other side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, the light transmitting surface 22 The display surface 12 arranged on the orientation adjusting surface 21 can be selectively observed easily. Further, the lights L22 and L51 to L53 incident on the solar cell composite display body 10 from the direction inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20 are directed from the orientation adjusting surface 21. The light transmitting surface 22 can lead to selection.

That is, according to such a form, the first angle range AR1 which is a viewing angle at which the display surface 12 arranged on the orientation adjusting surface 21 can be observed is the first axis with respect to the normal direction nd of the sheet member 20. A second angle range that corresponds to a direction inclined to the other side in the direction d1 and is an angle range in the direction of incidence on the solar cell composite display body 10 that is guided to the solar cell panel 50 via the light transmitting surface 22. AR2 corresponds to a direction inclined to one side in the first axial direction d1 with respect to the normal direction nd of the seat member 20. In other words, when the solar cell composite display 10 is observed from the direction inclined to the other side in the uniaxial direction d1, the display surface 12 is observed, and the solar cell composite display is observed from the direction inclined to one side in the uniaxial direction d1. The light incident on the 10 passes between the two adjacent display surfaces 12 and reaches the solar cell panel 50. In this case, the first angle range AR1 and the second angle range AR2 are easily separated. In other words, the first angle range AR1 and the second angle range AR2 are less likely to overlap.

If the overlap between the first angle range AR1 and the second angle range AR2 is reduced in this way, the display function of the display surface 12 and the power generation function of the solar cell panel 50 are more effectively exhibited without adversely affecting each other. Will be done. In the present embodiment, when observing the display object 13 attached to the display surface 12, it is possible to suppress the observation of the solar cell panel 50 together with the display object 13 through the light transmitting surface 22. It will be possible. In this case, the visibility of the display target 13 and the design of the display target 13 can be improved.

In particular, in the solar cell composite display body 10 according to the present embodiment, the first angle range AR1 which is a viewing angle at which the display surface 12 can be observed is set in a direction inclined downward in the vertical direction, and the solar cell panel 50 The second angle range AR2, which is the angle range in the direction of incidence on the solar cell composite display body 10 to be guided by the above, is set in the direction inclined upward in the vertical direction. In this case, it is effective when the solar cell composite display body 10 is installed at a position higher than the line of sight in the use as a display board which is assumed to be a typical use. Since the observer observes the solar cell composite display body 10 while looking up at the upper side in the vertical direction, the observer can observe the display target 13 provided to the display surface 12 from the first angle range AR1. On the other hand, the incident direction of sunlight changes depending on the time zone and the season, but the sunlight is incident on the solar cell composite display body 10 while advancing in the downwardly inclined direction in the vertical direction or in the substantially horizontal direction. Therefore, even if the incident direction changes depending on the time zone and the season, the sunlight can enter the light transmitting surface 22 from the second angle range AR2 and head toward the solar cell panel 50. Therefore, according to such a form, it is possible to effectively both receive sunlight by the solar cell panel 50 and display by the display surface 12.

Further, according to the present embodiment, in the main cut surface of the solar cell composite display body 10, the orientation adjusting surface 21 and the light transmitting surface 22 adjacent to the orientation adjusting surface 21 on the other side in the first axial direction d1. The distance dt along the first axial direction d1 becomes narrower as it approaches the solar cell panel 50 in the normal direction nd of the seat member 20. According to such a form, the display surface 12 arranged on the orientation adjusting surface 21 blocks the light to be incident on the light transmitting surface 22, or the light transmitting surface 22 is arranged on the orientation adjusting surface 21. It is possible to effectively suppress the obstruction of the observation of the displayed display surface 12. Therefore, when the display surface 12 observes the solar cell composite display body 10 from the direction within the first angle range AR1, the display function can be more reliably exhibited. Further, the light transmitting surface 22 can more reliably guide the light incident on the solar cell composite display body 10 from the second angle range AR2 to the solar cell panel 50.

By the way, Table 1 below shows the seasonal south-middle altitudes (°) in major cities in some countries of the world. It is preferable that the second angle range AR2 includes the mid-south altitude of the equinox in the major cities of the country where it is expected to be used. This is because there is a high possibility that it can be used effectively in that country. For example, if the country expected to be used is Japan, altitudes from 54 ° to 56 ° may be included in the second angle range AR2. Further, it is preferable that the altitude from 49 ° to 61 ° is included in the second angle range AR2 because it is highly possible that it can be effectively used in many countries in the world. Further, it is more preferable that the second angle range AR2 includes the mid-south altitude of the summer solstice to the mid-south altitude of the winter solstice in the major cities of the countries where the use is expected. This is because there is a high possibility that it can be used effectively throughout the year in that country. For example, if the country expected to be used is Japan, the altitude from 31 ° to 79 ° may be included in the second angle range AR2. Further, it is preferable that the altitude from 25 ° to 84 ° is included in the second angle range AR2 because it is highly possible that it can be effectively used in many countries in the world. In order to facilitate that the desired altitude is included in the second angle range AR2, it is preferable that the angle range of the second angle range AR2 is continuous by about 45 ° or more. However, it is also possible to include the desired altitude in the second angle range AR2 by arranging the solar cell composite display body 10 at an angle. On the other hand, the upper limit of the angle range of the second angle range AR2 may be appropriately set in balance with the first angle range AR1, but by setting it to less than about 135 °, the solar cell composite display of the present embodiment is displayed. The features of the body 10 can be further exhibited.

As described above, the solar cell composite display body 10 realizes both the display on the display surface 12 and the power generation by the solar cell panel 50 by utilizing the difference between the observation direction and the incident direction of the external light. , It is required to align with the installation object with high accuracy. Therefore, the solar cell composite display body 10 of the present embodiment has a frame member 70 so as to hold the seat member 20 and the solar cell panel 50 in an intended posture. The frame member 70 may support at least the solar cell panel 50, and the seat member 20 may be directly supported, indirectly supported via the solar cell panel 50, or the seat member. The seat member 20 may be supported by another member without supporting the 20.

FIG. 9 is a cross-sectional view showing how the frame member 70 holds the seat member 20 and the solar cell panel 50. As shown in FIG. 9, the frame member 70 extends from the back plate 76 arranged so as to face the back surface 50b of the solar cell panel 50 and the back plate 76 along the normal direction nd of the seat member 20, and is a sheet. It has a member 20 and a frame body 71 located around the solar cell panel 50.

The back plate 76 is arranged apart from the back surface 50b of the solar cell panel 50, and the electric device 55 connected to the solar cell panel 50 is placed in the space between the back plate 76 and the back surface 50b of the solar cell panel 50. It is contained. The electric device 55 includes a battery that stores electric energy generated by the solar cell panel 50, a control device that monitors the solar cell panel 50, and the like.

The frame body 71 faces the side surface 50c of the solar cell panel 50 and holds the solar cell panel 50. Further, the frame body 71 faces the side surface 20c of the seat member 20 and also holds the seat member 20. The side surface 20c of the seat member 20 is a surface extending between the first surface 20a and the second surface 20b. In the illustrated example, a pair of surfaces facing the first axial direction d1 and a second axis. It is composed of a pair of surfaces facing the direction d2.

Each frame body 71 extends from the back plate 76 toward the seat member 20 side along the normal direction nd of the seat member 20. In other words, the frame body 71 extends from the region opposite to the seat member 20 with respect to the solar cell panel 50 toward the seat member 20 side along the normal direction nd of the seat member 20. Then, a tip surface 74 facing the normal direction nd of the sheet member 20 is formed at the protruding tip.

Further, the frame body 71 shown in FIG. 9 extends toward the seat member 20 side from the light receiving surface 50a of the solar cell panel 50, and further extends beyond the first surface 20a of the seat member 20 to reach the first surface 20a. It protrudes from the sheet member 20 in the normal direction nd. Therefore, the tip surface 74 of the frame body 71 is located on the opposite side of the solar cell panel 50 with respect to the first surface 20a of the seat member 20. By projecting the frame body 71 beyond the first surface 20a of the seat member 20 in this way, the seat member 20 and the solar cell panel 50 can be protected from collision with obstacles.

However, this protruding portion can also be a factor that blocks the sunlight L91 incident on the sheet member 20. Therefore, in the present embodiment, at least a part of the region 71a of the frame body 71 extending toward the seat member 20 from the light receiving surface 50a of the solar cell panel 50 is provided with light transmission. According to such a form, it is possible to reduce the possibility that the region 71a extending beyond the light receiving surface 50a blocks the light L91 incident on the sheet member 20. In the example shown in FIG. 9, the entire region 71a extending from the light receiving surface 50a is made of a transparent material having light transmission. Examples of such materials include glass and transparent resin materials.

In particular, the frame body 71 shown in FIG. 9 includes a first frame 72 and a second frame 73 arranged so as to face each other in the first axial direction d1. The first frame 72 is located on one side in the first axial direction d1, and faces the side surface 20c of the seat member 20 and the side surface 50c of the solar cell panel 50 from one side. The second frame 73 is located on the other side in the first axial direction d1, and faces the side surface 20c of the seat member 20 and the side surface 50c of the solar cell panel 50 from the other side. However, the configuration of the frame body 71 is not limited to such an example. In addition to the first frame 72 and the second frame 73, the frame body 71 may further include a pair of frames arranged so as to face each other in the second axial direction d2, and the first frame 72 and the second frame 73 may include a pair of frames. Alternatively, a pair of frames facing the second axial direction d2 may be included.

In the example shown in FIG. 9, a plurality of grooves 81 are formed in the first frame 72 and the second frame 73, and the seat member 20 and the solar cell panel 50 are fitted into the corresponding grooves 81. By using the groove 81, the seat member 20 and the solar cell panel 50 can be detachably attached to the frame member 70.

Further, the frame body 71 holds the solar cell panel 50 and the seat member 20 at intervals, and the above-mentioned air layer 30 is interposed between them. Further, since the entire area 71a of the frame body 71 extending toward the seat member 20 side from the light receiving surface 50a of the solar cell panel 50 has light transmission, naturally, the sheet of the frame body 71. The region 71b between the solar cell panel 50 and the seat member 20 in the normal direction nd of the member 20 also has light transmission. Therefore, the light L92 directed toward the solar cell panel 50 can be taken in from the region 71b during this period as well.

As described above, according to the present embodiment, at least the frame member 70 for holding the solar cell panel 50 is further provided. The provision of the frame member 70 contributes to the stable installation of the solar cell panel 50 on the installation target.

Further, according to the present embodiment, the solar cell panel 50 has a light receiving surface 50a facing the second surface 20b of the sheet member 20, a back surface 50b facing the light receiving surface 50a, and a light receiving surface 50a and a back surface 50b. The frame member 70 has a side surface 50c extending between them, and the frame member 70 has a frame body 71 that faces the side surface 50c of the solar cell panel 50 and holds the solar cell panel 50, and the frame body 71 is a solar cell panel. It extends from a region opposite to the seat member 20 with reference to 50 toward the seat member 20 side along the normal direction nd of the seat member 20. According to such a form, since the solar cell panel 50 can be held by the side surface 50c, the possibility that the light receiving surface 50a is blocked by the frame member 70 can be reduced. As a result, it is excellent in that the power generation by the solar cell panel 50 can be effectively performed.

Further, according to the present embodiment, the frame body 71 protrudes toward the seat member 20 side from the light receiving surface 50a of the solar cell panel 50. By projecting the frame body 71 beyond the light receiving surface 50a, the solar cell panel 50 can be protected from collision with an obstacle. Further, the frame body 71 extends from the second surface 20b side of the seat member 20 beyond the first surface 20a, and protrudes from the first surface 20a in the normal direction nd of the seat member 20. By projecting the frame body 71 beyond the first surface 20a of the seat member 20, the seat member 20 in addition to the solar cell panel 50 can be protected from collision with an obstacle.

Further, according to the present embodiment, the frame body 71 holds the solar cell panel 50 and the seat member 20 at intervals. In this case, scratches and wear due to contact between the light receiving surface 50a of the solar cell panel 50 and the second surface 20b of the sheet member 20 can be avoided. Further, in the frame body 71, the region 71b between the solar cell panel 50 and the seat member 50 in the normal direction nd of the seat member 20 has light transmission. Therefore, a part of the light L92 toward the solar cell panel 50 can be taken in from the region 71b between the solar cell panel 50 and the seat member 50 without going through the seat member 20.

Further, according to the present embodiment, at least a part of the region 71a of the frame body 71 extending toward the seat member 20 side from the light receiving surface 50a of the solar cell panel 50 has light transmission property. According to such a form, it is possible to reduce the possibility that the region 71a extending beyond the light receiving surface 50a blocks the light L91 incident on the sheet member 20.

<< Deformation example of frame member 70 >>
It is possible to make various changes to the above-mentioned form. Hereinafter, an example of modification will be described with reference to the drawings. In the following description and the drawings used in the following description, the same codes as those used for the corresponding parts in the above-described embodiment will be used for the parts that can be configured in the same manner as in the above-described embodiment. Duplicate explanations will be omitted.

In the above-described embodiment, as shown in FIG. 2, an example is shown in which the entire region 71a of the frame body 71 extending toward the seat member 20 side from the solar cell panel 50 has light transmission. The configuration of the frame body 71 is not limited to the above-described configuration. 10 and 11 show other configuration examples of the frame body 71, respectively. In the example shown in FIG. 10, the region 71a of the frame body 71 extending toward the seat member 20 from the light receiving surface 50a of the solar cell panel 50 is reflected on the surface facing the side surface 50c of the solar cell panel 50. It has a surface 75. In the example shown in FIG. 10, the reflection processing surface 75 provided on the first frame 72 faces the side surface 20c of the seat member 20 from one side in the first axial direction d1, and the reflection processing surface 75 is provided on the second frame 73. The surface 75 faces the side surface 20c of the seat member 20 from the other side in the first axial direction d1.

As an example, the reflection-treated surface 75 is formed of a thin film made of a material having high reflectance, for example, a metal such as aluminum. Further, in order to guide the light reflected by the reflection processing surface 75 to a wide range of the light receiving surface 50a of the solar cell panel 50, the reflection processing surface 75 preferably has a light diffusion function. An example of such a reflection-treated surface 75 is a layer made of white ink.

According to the reflection processing surface 75, the light L101 and L102 incident on the region 71a extending toward the sheet member 20 side from the light receiving surface 50a of the solar cell panel 50 in the frame body 71 are transferred to the sheet member 20 or the solar cell panel. Since it can be directed to 50, the light utilization efficiency can be improved.

Further, in the example shown in FIG. 10, the sheet member 20 is bonded to the solar cell panel 50 via the low refractive index resin layer 35. The low refractive index resin layer 35 is made of a material having a lower refractive index than the material forming the sheet member 20, and an example thereof includes a transparent thermoplastic resin.

On the other hand, in the example shown in FIG. 11, the region 71b of the frame body 71 between the solar cell panel 50 and the seat member 50 in the normal direction nd of the seat member 20 is made of a material that transmits light. On the other hand, the region 71c of the frame body 71 that overlaps with the side surface 20c of the seat member 20 is made of a material that does not transmit light. Specifically, the former region 71b is composed of glass or a transparent resin material, and the latter region 71c is composed of a wooden frame or a resin material colored in black.

Even in the form shown in FIG. 11, the frame body 71 holds the solar cell panel 50 and the seat member 20 at intervals. In this case, scratches and wear due to contact between the light receiving surface 50a of the solar cell panel 50 and the second surface 20b of the sheet member 20 can be avoided. Further, in the frame body 71, the region 71b between the solar cell panel 50 and the seat member 50 in the normal direction nd of the seat member 20 has light transmission. Therefore, a part of the light L92 toward the solar cell panel 50 can be taken in from the region 71b between the solar cell panel 50 and the seat member 50 without going through the seat member 20.

Further, in the example shown in FIG. 11, the tip surface 74 of the frame body 71 coincides with the position of the first surface 20a of the seat member 20 along the normal direction nd of the seat member 20. That is, the tip surface 74 of the frame body 71 does not form a step with the first surface 20a of the sheet member 20, and is smoothly connected to form a flat surface. According to such a form, it is possible to reduce the possibility that the solar cell panel 50 is held by the frame body 71 and the light L 121 to be incident on the sheet member 20 is blocked by the frame body 71.

Further, in the above-described embodiment, as shown in FIG. 2, an example is shown in which the frame body 71 extends toward the seat member 20 side from the light receiving surface 50a of the solar cell panel 50, but the configuration of the frame body 71 is , The configuration is not limited to the above. 12 and 13, respectively, show other configuration examples of the frame body 71. Of these, in the example shown in FIG. 12, the front end surface 74 of the frame body 71 is located at a position between the light receiving surface 50a and the back surface 50b of the solar cell panel 50 in the normal direction nd of the seat member 20. ..

In the example shown in FIG. 12, the frame body 71 holds the side surface 50c of the solar cell panel 50. Further, the sheet member 20 is bonded to the solar cell panel 50 via the low refractive index resin layer 35. The low refractive index resin layer 35 is made of a material having a lower refractive index than the material forming the sheet member 20, and an example thereof includes a transparent thermoplastic resin.

According to the form shown in FIG. 12, the solar cell panel 50 can be held by the frame body 71, and the possibility that the frame body 71 blocks the light L121 to be incident on the sheet member 20 can be reduced. Further, a part of the light L122 toward the solar cell panel 50 can be taken in from the low refractive index resin layer 35 between the solar cell panel 50 and the sheet member 50 without going through the sheet member 20.

On the other hand, in the example shown in FIG. 13, the position of the tip surface 74 of the frame body 71 coincides with the position of the light receiving surface 50a of the solar cell panel 50 along the normal direction nd of the sheet member 20. That is, the tip surface 74 of the frame body 71 is smoothly connected to the light receiving surface 50a of the solar cell panel 50 to form a flat surface, and no step is formed between the light receiving surface 50a and the light receiving surface 50a. According to such a form, it is possible to reduce the possibility that the solar cell panel 50 is held by the frame body 71 and the light L131 that should be incident on the sheet member 20 is blocked by the frame body 71. Further, a part of the light L132 toward the solar cell panel 50 can be taken in from the low refractive index resin layer 35 between the solar cell panel 50 and the sheet member 50 without going through the sheet member 20.

Further, in the example shown in FIG. 13, the seat member 20 covers the tip surface 74 of the frame body 71. In this case, since the tip surface 74 of the frame body 71 can be hidden by the sheet member 20 in which the plurality of display surfaces 12 are arranged, the appearance can be improved.

Further, in the above-described embodiment, as shown in FIG. 9, an example in which the seat member 20 and the solar cell panel 50 are held by the frame body 71 so as to be parallel to each other is shown, but the configuration of the frame body 71 is shown. Is not limited to the above-described configuration. 14 and 15 show other configuration examples of the frame body 71, respectively. Of these, in the example shown in FIG. 14, the frame body 71 holds the seat member 20 in a removable manner and the solar cell panel 50 in an adjustable orientation.

A plurality of grooves 81 are formed in the first frame 72 and the second frame 73 constituting the frame body 71.

In the example shown in FIG. 27, the solar cell composite display body 10 has a sheet-shaped sheet member 20 and a solar cell panel 50 arranged so as to face the second surface 20b of the sheet member 20.

The first surface 20a of the sheet member 20 includes a plurality of lens surfaces 31 arranged in the first axial direction d1. The plurality of lens surfaces 31 are arranged so that their optical axes od are parallel to each other. In particular, in the illustrated example, the lens surface 31 is arranged so that its optical axis od is parallel to the normal direction nd of the solar cell composite display body 10.

The lens surface 31 constitutes a so-called lenticular lens or a cylindrical lens. That is, each lens surface 31 extends linearly in a direction intersecting the first axial direction d1 which is the arrangement direction thereof, and more specifically in a second direction d2 orthogonal to the first axial direction d1.

A plurality of display surfaces 12 are arranged in the sheet member 20 along the first axial direction d1 corresponding to the lens surface 31. As shown in FIG. 27, each display surface 12 is arranged so as to face the corresponding lens surface 31 at least partially along the normal direction nd. In the present embodiment, the display surface 12 is in the direction intersecting the first axial direction d1 which is the arrangement direction, more precisely, in the second direction d2 orthogonal to the first axial direction d1, like the lens surface 31. It extends in a straight line. Further, each display surface 12 is inclined with respect to the panel surface of the solar cell panel 50 and the normal direction nd of the seat member 20.

Next, the operation of the solar cell composite display body 10 according to the present embodiment will be described.

As is well shown in FIG. 27, the inclined display surface 12 is easily visible from the front direction of the display surface 12. In the present embodiment, since the display surface 12 is inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, in the first axial direction d1 with respect to the normal direction nd. When observing the solar cell composite display body 10 from the directions D271 and D272 inclined to the other side, the display surface 12 becomes easy to see. In particular, even when the solar cell composite display body 10 is observed from the direction D272 which is greatly inclined to the other side in the first axial direction d1 with respect to the normal direction nd, it is incident due to the condensing action of the lens surface 31. The display surface 12 facing the lens surface 31 can be observed. If a plurality of display surfaces 12 are arranged on the second surface 20b of the sheet member 20 along the second surface 20b, they are adjacent to the lens surface 31 to be observed as shown by the dotted line in FIG. 27. The display surface 12 facing the lens surface 31 may be observed, and the intended display function may not be exhibited. That is, by inclining the display surface 12 with respect to the panel surface of the solar cell panel 50, the first angle range AR1 which is the viewing angle at which the display surface 12 is observed is, in other words, the emission of light from the display surface 12. The first angle range AR1, which is the angle range of the direction, can be adjusted with a high degree of freedom.

On the other hand, the light flux L273 traveling in the sheet member 20 from a direction in which the angle formed with respect to the display surface 12 is smaller is less likely to be received by the display surface 12. From this, as shown in FIG. 27, the luminous flux L273 toward the solar cell panel 50 without being blocked by the inclined display surface 12 is inclined in the direction opposite to the directions D271 and D272 in which the display surface 12 can be effectively observed. The luminous flux is L273. That is, the light incident on the lens surface 31 while advancing to the other side in the first axial direction d1, and the light flux L273 incident on the lens surface 31 advancing downward in the vertical direction in the illustrated example, are between the two display surfaces 12. It is easy to be guided to the solar cell panel 50 through the region 60.

As described above, according to the form shown in FIG. 27, the seat member 20 having the first surface 20a and the second surface 20b facing the first surface 20a and the sheet member 20 facing the second surface 20b of the sheet member 20 are arranged. A plurality of display surfaces 12 each of which are inclined with respect to the panel surface of the solar cell panel 50 are arranged along the uniaxial direction d1 on the seat member 20. According to such a solar cell composite display body 10, since the display surface 12 is inclined with respect to the panel surface of the solar cell panel 50, the inclined display surface 12 is in the front direction from the directions D271 and D272. It becomes easier to observe. On the other hand, the luminous flux L273 incident on the solar cell composite display body 10 from a direction different from the directions D271 and D272 where the display surface 12 is easily visible passes between the two adjacent display surfaces 12 and is transmitted through the solar cell panel. Guided to 50. In this way, by utilizing the difference between the observation directions D271 and D272 from the observer and the incident direction of the external light L273, harmony with the surrounding environment is achieved, and the display by the display surface 12 and the power generation by the solar cell panel 50 are achieved. Can be effectively achieved at the same time. Moreover, since the solar cell panel 50 is arranged so as to face the second surface 20b of the sheet member 20, the light receiving surface 50a of the solar cell panel 50 is not exposed to the outside. Therefore, the solar cell panel 50 can be made more inconspicuous.

Further, according to the present embodiment, the plurality of display surfaces 12 are arranged inside the seat member 20. In this case, it is advantageous that the display surface 12 can be protected by the material forming the sheet member 20.

Further, the first surface 20a of the sheet member 20 includes a plurality of lens surfaces 31 arranged in the uniaxial direction d1, and the lens surface 31 guides light coming from D271 and D272 in a certain direction to the display surface 12. Light L273 incident from a different direction from one direction D271 and D272 is transmitted between two adjacent display surfaces 12 and guided to the solar panel 50. According to such a form, the first angle range AR1 in which the display surface 12 is the viewing angle to be observed and the second angle range AR2 in which power generation by the solar cell panel 50 is effectively performed by the condensing action of the lens surface 31. Can be adjusted with a high degree of freedom.

The sheet member 20 shown in FIGS. 21 to 27 can naturally be used in combination with the frame member 70 described with reference to FIGS. 9 to 20. That is, the solar cell composite display body 10 shown in FIGS. 21 to 27 can further include the above-mentioned frame member 70 that holds at least the solar cell panel 50. The provision of the frame member 70 contributes to the stable installation of the solar cell panel 50 on the installation target.

Further, according to the solar cell composite display body 10 shown in FIGS. 21 to 27, the solar cell panel 50 has a light receiving surface 50a facing the second surface 20b of the sheet member 20 and a back surface 50b facing the light receiving surface 50a. And a side surface 50c extending between the light receiving surface 50a and the back surface 50b, and the frame member 70 has a frame body 71 that faces the side surface 50c of the solar cell panel 50 and holds the solar cell panel 50. However, the frame body 71 may extend from the region opposite to the seat member 20 with respect to the solar cell panel 50 toward the seat member 20 side along the normal direction nd of the seat member 20. According to such a form, since the solar cell panel 50 can be held by the side surface 50c, the possibility that the light receiving surface 50a is blocked by the frame member 70 can be reduced. As a result, it is excellent in that the power generation by the solar cell panel 50 can be effectively performed.
