DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, a support block 12 is provided at a predetermined interval on a mounting surface 11 such as a roof or a wall of a building. A frame 13 is fixedly disposed on the support block 12, and a gap 14 for venting air is formed between the lower end of the frame 13 and the mounting surface 11 between the support blocks 12. The solar cell panel 15 is attached to the frame 13 so as to be inclined in the south direction.

On the back side of the solar cell panel 15, a plurality of fins 17 constituting an operation means are erected and supported between both side frames of the frame 13. These fins 17 are formed in a wing cross-sectional shape (asymmetric wing) having a planar upper surface 17a and a curved convex lower surface 17b, and are arranged in a horizontal plane along the direction of wind W1 flowing on the back surface side of solar cell panel 15. Are arranged at the same angle α1 (for example, 30 degrees). Then, the wind W1 blowing on the back side of the solar cell panel 15 is
A downward lift is generated by flowing along the lower surface 17b, and a force P1 acts on the solar cell panel 15 via the frame 13 toward the mounting surface 11 by the lift. The fins 17 preferably have a high aspect ratio so that a large lift can be generated.

Rectifying fins 18 are erected and supported between the support blocks 12 in the air vent clearance 14. The fin 18 is formed in a wing cross-sectional shape (symmetric wing) having substantially the same curved convex upper surface 18a and lower surface 18b, and has an angle α2 (eg, 5 degrees) smaller than the angle α1 of the fin 17 with respect to the horizontal plane. It is arranged in a state of making. The wind W1 blowing on the back side of the solar cell panel 15 is guided by the rectifying fins 18 to the front side of the solar cell panel 15 through the gap 14 for air release.

Next, the operation of the solar cell device configured as described above will be described. Now, in this solar cell device, the solar cell panel 15 is mounted on the mounting surface 11 such as the rooftop or wall surface of the building via the frame 11 so as to be inclined in the south direction. Therefore, when wind is blown against the solar cell panel 15 from the front side, a force acts on the solar cell panel 15 so as to press the solar cell panel 15 against the mounting surface 11 side. For this reason, no force acts on the solar cell panel 15 in the direction of floating from the mounting surface 11.

On the other hand, when wind is blown from the back side of the solar cell panel 15, a force acts on the solar cell panel 15 in a direction to float from the mounting surface 11. However, a plurality of fins 17 having a wing cross section are provided on the back side of the solar cell panel 15. For this reason,
The wind W1 blowing on the back surface side of the solar cell panel 15 flows along the upper surface 17a and the lower surface 17b of these fins 17 to generate a downward lift, and the lift causes the solar cell device to move toward the mounting surface 11 side. Pressing force P1 acts. Therefore, no force acts on the solar cell device in the direction in which it floats due to the wind from the rear surface side.

The lower end of the frame 13 and the mounting surface 11
A gap 14 for venting air is formed between them. Therefore, the wind W <b> 1 blowing on the back surface side of the solar cell panel 15 does not accumulate between the lower end of the frame 13 and the mounting surface 11, and flows to the front side of the solar cell panel 15 through the air gap 14. Guided smoothly. Therefore, the flow of the wind reliably acts on the fins 17, and no air pockets are formed on the back side of the solar cell panel 15, and the wind rises from the mounting surface 11 with respect to the solar cell panel 15. No force acts.

Further, rectifying fins 18 are provided in the gaps 14. Therefore, the solar cell panel 1
The wind W <b> 1 passing through the gap 14 from the back side of the rectifier 5 is rectified and guided smoothly by the guidance of the rectifying fins 18. Therefore, it is possible to reliably generate the above-described lift and the like.

The effects that can be expected from the above embodiment will be described below. (A) The fins 17 are disposed on the back surface side of the solar cell panel 15, and the wind W1 blowing on the back surface side of the solar cell panel 15 passes over the fins 17, so that the solar cell panel 1
5 is applied to the mounting surface 11 side.

Accordingly, it is possible to suppress the force acting on the solar cell panel 15 in the direction of floating from the mounting surface 11 by the wind W1 blowing on the back surface side. For this reason, even if the solar electric wind W1 is strong, the possibility that the solar cell panel 15 is blown off can be prevented, vibration and noise can be suppressed, and a lightweight and simple mounting method can be used.

(B) On the back side of the solar cell panel 15,
Fins 17 having a wing cross-sectional shape are provided. for that reason,
The solar cell panel 1 is formed by the fins 17 having the wing cross section.
5 can easily generate a force toward the mounting surface 11 while suppressing vibration and noise.

(C) A plurality of fins 17 are arranged along the direction of the flow of the wind W1. Therefore, the mounting surface 1 with respect to the solar cell panel 15 is formed by the plurality of fins 17.
A force toward one side can be generated more effectively.

(D) End of frame 13 and mounting surface 11
Is formed between them, the wind W1 blows through the gap 14 for drafting. For this reason, it is possible to prevent the wind W <b> 1 from accumulating between the end portion of the frame 13 and the mounting surface 11, and it is possible to obtain the lift by reliably acting the flow of the wind on the fins 17. .

(E) Since the rectifying fins 18 are provided in the gaps 14, the flow of the wind W 1 in the drafting gaps 14 can be improved by the rectifying fins 18. The effect of preventing the accumulation of W1 and the effect of rectifying the fins 17 can be enhanced, and the solar cell panel 1 can be improved.
5 can be reliably prevented from rising.

Angle α larger than angle α2
3 (for example, 25 degrees).

For this reason, when the wind W1 blows on the back side of the solar cell panel 15, the wind W1 is blown in the same manner as in the first embodiment.

5 is arranged so as to approach the rear surface side.

Therefore, when the wind W1 blows on the back surface side of the solar cell panel 15, the wind W1 flows along the upper and lower surfaces of the uppermost fin 17, thereby generating a lift. , A pressing force P1 against the mounting surface 11 acts. In addition, the wind W1 is blown onto the lower three fins 20 at an angle of attack β1, so that a pressing force P2 against the mounting surface 11 acts on the solar cell panel 15.
