[0008] The light-receiving surface portion 2 extends laterally at an inclination angle of about 45°, for example, toward the sun. The upper edge is connected to the above-mentioned attached surface portion 3 at the upper edge to form an upper edge connecting portion 5. above this A flat fastening piece 6 is extended diagonally upward from the edge connecting part 5 to the front side, and the construction An upper hook portion 8 having a downward hook-shaped locking piece 7 is extended toward the structure. Furthermore, above The inclination angle of the recording/receiving surface section 2 is based on the annual average of the area where the photothermal hybrid panel 1 is installed. It is desirable to determine the value according to the uniform solar altitude, but it is possible to make it as a standard product. It may also be adjusted during installation.

[0009] A solar cell 9 is arranged on the light-receiving surface section 2 as described above, and the surface is made of glass or wood. Cover with a protective layer of fat. That is, as shown in FIG. A substrate layer 10 consisting of a frame is formed, and cells 9' of the solar cell 9 are formed on this substrate layer 10. is formed and covered with a protective layer 11.

0010 On the other hand, a closing surface portion 4 is extended from the lower edge of the light receiving surface portion 2 toward the lower edge of the attached surface portion 3. The space 12, which has a substantially triangular cross-sectional shape and is surrounded by the light-receiving surface section 2 and the attached surface section 3, is closed. block it. In addition, a partition portion 13 along the longitudinal direction is provided in this triangular space 12. Divided into a plurality of spaces 12... In the illustrated embodiment, the light receiving surface 2 is approximately parallel to the light receiving surface section 2. It is divided into three spaces by two partitions 13a and 13b, and the light-receiving surface 2 side There are a first space 12a, a second space 12b, and a third space 12c. The space 12a and the third space 12c are used as flow paths for the heat medium.

[0011] From the intersection where the attachment surface section 3 and the closing surface section 4 communicate, the lower hook section 14 extend towards the building. This lower hook portion 14 has a hook shape that faces forward in a folded manner. It has an engaging piece 15.

0012 In addition, a rainwater guiding portion 16 is provided at the front end portion where the light receiving surface portion 2 and the closing surface portion 4 communicate with each other. Form into a curved surface. This rainwater guiding section 16 directs rainwater falling onto the light receiving surface section 2 from the front end. This is to guide it to the bottom side without causing it to fall.

[0013] Furthermore, a space for wiring and piping is formed on the lower surface side of the closed surface portion 4. The space is closed by a cover plate 17. This cover plate 17 is The upper edge is placed in a locking groove 18 provided near the front edge of the closing surface portion 4 and opening diagonally rearward. At the same time as inserting the It is fixed with screw 19 etc.

[0014] The rainwater guide portion 16 is formed as described above, and the cover plate 17 is provided. Then, the photothermal hybrid panel 1 can be given a self-cleaning effect, and the conversion efficiency can be increased. It is possible to prevent a decrease in That is, dust etc. adhere to the protective layer 11 of the solar cell 9. However, even when it rains, rainwater is directed along the cover plate 17 by the rainwater guide section 16. As it flows, the upper surface of the protective layer 11 of the photothermal hybrid panel 1 located at the lower stage is Flow down. Therefore, the outer surface of the protective layer 11 is washed by this falling rainwater, Sunlight is blocked by dust etc. attached to the protective layer 11 of the solar cell 9, and the solar cell The conversion efficiency of the pond 9 does not decrease.

[0015] To attach the photothermal hybrid panel 1 as described above to the wall a of a building, Attach the fixing hardware 20 to the light-thermal hybrid panel 1 on the south-facing wall a of the building. The anchor bolts 21, etc., with the corresponding vertical width, and at appropriate intervals in the horizontal direction, or horizontally long. Fix it by tightening it or burying it in advance. This fixed hardware 20 is, for example, Receiving parts 22 and supports corresponding to the upper and lower hook parts 8 and 14 of the hybrid panel 1 It has a mounting part 23, and a photothermal hybrid panel is attached to the receiving part 22 of the upper fixed hardware 20. The upper hook part 8 of 1 is locked, and the lower hook part 14 is attached to the support hardware attachment part 23. Attach the support hardware 24 to the front surface of the support hardware attachment part 23 with screws 25, etc., and lower it. The hook portion 14 is fixed. Then, insert the tip of the cover plate 17 into the engagement groove 18. Attach the screw 19 to the fixing piece 6 of the photothermal hybrid panel 1 located at the lower end. You can fix it with etc.

[0016] In this way, the photothermal hybrid panels 1 are sequentially attached to the wall a of the building, especially facing south. The wiring piping space 26 formed below the closed surface part 4 is utilized. The wiring 27 of the solar cell 9 can be arranged using the A heat-treated pipe 28 is provided.

[0017] When sunlight irradiates the photothermal hybrid panel 1 arranged as described above, This solar energy is converted into electric power by the solar cell 9, and the heat medium is A heat transfer medium passing through a channel, for example, increases the temperature of water to supply hot water or operate a heat pump. By circulating the fluid through the heat medium flow path, it can also be used for heating and cooling.

[0018] 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. Alternatively, a heat medium for cooling may be passed through this first space to cool the solar cell. You may also do so.

[0019]

[Effect of the idea]

According to the photothermal hybrid panel of this invention, sunlight energy is generated using solar cells.
