Therefore, the heat medium is cooled or The temperature of the solar cell 15 will not rise and the conversion efficiency will not decrease.

[0011] In the panel main body part 2 as described above, the first attachment from the lower edge of the light receiving surface part 5 to the front side While extending the hem portion 3 downward, the second mounting hem portion 4 on the rear side is extended from the lower edge of the vertical plate portion 7. Extend downward.

0012 The first mounting hem 3 extends from the connecting portion between the light-receiving surface portion 5 and the closing surface portion 9 to the horizontal plate portion 10. It hangs down almost vertically through the front edge of the first mounting hem 3, and on the inner surface of the first mounting hem 3, there are suitable At a height position, for example, at a position slightly closer to the lower end than the middle stage, the tip of the support hardware 16, which will be described later, A first engagement receiving portion 17 is provided that protrudes inward so that the end locking portion can be locked.

[0013] On the other hand, the second mounting hem portion 4 on the rear side continuously extends downward from the vertical plate portion 7, and It is formed almost symmetrically with the first mounting hem 3 described above. That is, from the vertical plate part 7, It hangs down and extends downward in a substantially vertical direction from the connecting part between the horizontal plate part 10 and the vertical plate part 7. do. Also, on the inner surface of the second mounting hem 4, similar to the first engagement receiving portion 17 described above, A second engagement receiving part 18 is provided in which the engagement part of the support hardware 16 can be engaged. In addition, as mentioned above From the connecting portion between the vertical surface portion 6 and the closed surface portion 9 to the connecting portion between the vertical plate portion 7 and the horizontal plate portion 10.

[0014] A solar cell 15 is disposed on the light-receiving surface section 5 as described above, and the surface is made of glass. It is covered with a protective layer 20 made of resin. That is, as shown in the enlarged section of Figure 1, the insulation A cell 15' of a solar cell 15 is formed on a substrate layer 21 consisting of a solar cell and a protective layer 20 is formed. The coated material is attached to the surface of the light receiving surface section 5.

[0015] Next, the photothermal hybrid panel 1 having the above configuration is attached to the top of the building frame. For example, when attaching it to the top of the rising part a of a rooftop parapet to form a cap. Explain the case. First, anchor the support hardware 16 on the top surface of the rising part a of the parapet. 22, the supporting hardware 16 is attached to both edges of the substantially flat base plate 23. A low-height standing portion 24 is provided at The plate portion 25 is extended, and a locking plate portion 26 is further extended from the outer end of the support plate portion 25 to widen toward the end. It will be done. The portion from the support plate portion 25 to the locking plate portion 26 is shaped to be elastically deformable. It has been completed. Then, the support hardware 16 as described above is attached to the substrate via the pedestal member 16. The anchor 22 is used to prevent the section 23 from coming into close contact with the upper surface of the rising section a of the parapet. and fix it. Note that the supporting hardware 16 is a long member disposed along the length direction of the rising portion a. However, they may be short members arranged at appropriate intervals.

[0016] A photothermal hybrid according to the present invention is placed above the supporting hardware 16 fixed as described above. With the head panel 1 facing forward, the first mounting hem 3 is attached to the locking plate 26 on the front side of the support hardware 16. At the same time as positioning the second mounting hem 4 to the rear side of the support hardware 16, the locking plate 26 position above. Then, when the photothermal hybrid panel 1 is pressed downward, Since both the engagement receiving parts 17 and 18 come into contact with the slope of each locking plate part 26, each locking plate part 26 is elastically deformed to avoid the engagement receiving portions 17 and 18, and the engagement receiving portions 17 and 18 26, each locking plate portion 26 returns to its original state, and the tip of each locking plate portion 26 They engage with the engagement receiving portions 17 and 18, respectively. Therefore, in this state, the photothermal hybrid Panel 1 cannot be removed upwards, so it will not fall off even if strong winds blow. .

[0017] Photothermal hybrid panel 1 attached to the top of the parapet as described above , the wiring 28 of the solar cell 15 is arranged behind the vertical plate part 7, and the wiring 28 of the heat medium is arranged behind the vertical plate part 7. A heat-insulated pipe 29 is provided to form a circulation path. And these It is preferable to cover the wiring and piping with a weathering cover 30. This weather The ring cover 30 has a bent surface portion 30a, a back surface portion 30b, and a drain portion 30c. It is a bendable member and is attached through a mounting piece 30d formed at the upper end of the slope portion 30a. Screw the screw 31 into the vicinity of the upper end of the vertical plate portion 7. In addition, the tip of this mounting screw 31 is on the back side. Since it enters the side air layer portion 13, the screwing operation is facilitated. Also, this website Zaring Cover 30 can be used as a covering material for electric wires used for wiring, connectors, and piping. Deterioration of insulation materials, etc. due to exposure and electrical failure are extremely reduced.

[0018] When sunlight irradiates the photothermal hybrid panel 1 arranged as described above, This solar energy is converted into electric power by the solar cell 15, and the heat medium A heat medium passing through a flow path, for example, increases the temperature of water to enable hot water supply, or a heat pump. It can also be used for heating and cooling by circulating the working fluid of the pump through the heat medium flow path. can.

[0019] In addition, since the photothermal hybrid panel 1 itself forms the cap, it is not possible to It becomes possible to effectively utilize unused parts of the building. In addition, the light and heat Ideally, the parapet etc. on which the hybrid panel 1 is installed should face north and south. However, if this is not possible due to locational conditions, it may be sufficient to install it in a location facing east and west. Effective in minutes. At this time, if the inclination angle of the light receiving surface section 5 is relatively low, , can receive light over a wide range. Also, do not install the photothermal hybrid panel 1. For small parapets, etc., it is also possible to install a cap that has the same shape on the outside, making it more aesthetically pleasing. It is also possible to unify the

[0020] Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is limited to the embodiments described above. Unless the structure stated in the scope of the claim for utility model registration is changed. It can be implemented as appropriate. For example, by forming more spaces, each space has different heat. A heat insulating layer can be created by passing a medium through or using the first space immediately on the back side of the solar cell as an air layer. may be formed.
