[0020]

Embodiments of the present invention will be described below with reference to the drawings. First Embodiment FIG. 1 shows a unit building constructed using a roof panel according to a first embodiment of the present invention, that is, a unit building having a gable roof having a photothermal hybrid module installed on a roof surface. ing. As shown in FIG. 2, this unit building is divided into living room units A1, A2, B1, B2,.
And roof units C1, C constituting the roof of the house
, And C3,... And roof panels P1,.

These units are produced in a factory in advance, transported to a construction site, constructed and assembled in order to increase the industrial production rate of the house. Assembling is performed by first installing the lower-floor living room units A1, A2,... On the foundation and interconnecting them, and then installing the lower-floor living room unit A previously installed.
1, A2, ..., upper floor living room units B1, B
Are installed and connected to each other, and the corresponding roof units C1,
Put the roof panels P1, ... on the roof surface of C2, C3 ...
This is done by interconnecting. 1 and 2
Here, only the roof panel P1 on the roof surface that is well exposed to sunlight is illustrated, and other roof panels are not illustrated.

FIG. 3 shows the appearance of a roof panel P1 with a photothermal hybrid module of this embodiment. The roof panel P1 includes a roof panel main body 1 having a roof surface plate portion 1A, and a plurality of roof panels P1 mounted on the flat surface (the upper surface of the roof surface plate portion) in a horizontal row (in a direction orthogonal to the flow direction of the inclined roof surface). Of the photothermal hybrid module 10, a plurality of solar cell modules 11 attached to the lower side in two horizontal examples, and a plurality of mounting bases for installing the photothermal hybrid module 10 and the solar cell module 11 (hereinafter, referred to as both modules). And a frame 2 composed of a vertical frame member and a horizontal frame member. Although not particularly shown, the roof surface plate portion 1A is provided with a waterproof sheet such as asphalt roofing on an upper surface of a base plate (roof base material) such as a structural plywood or a particle board. It is constituted by sticking a non-combustible coating material such as a steel plate (polyvinyl chloride metal laminate), and provided with a roofing material such as a folded plate, a slate or a tile as required.

The roof panel main body 1 has a connecting means (not shown) on the rear surface side of the roof face plate portion 1A with a member coming below this. The structure on the back side is replaced by the structure of the lower member, and when the lower member does not have a roof surface, it is strong and waterproof because the roof panel P1 alone forms the roof surface. It is necessary to have a sufficient structure. When the member coming on the lower side has a roof surface, both the main roof panel P1 and the member coming on the lower side have strength,
What is necessary is just to make sufficient structure waterproof.

FIGS. 4 to 6 are views showing a procedure for assembling the roof panel P1, and FIGS. 7 and 8 are sectional views taken along arrows AA and BB in FIG. 3, respectively. 9 and 10 are views during the assembly of the roof panel P1, FIGS. 11 and 12 are diagrams illustrating the configuration of the photothermal hybrid module, and FIG. 13 is a diagram illustrating the configuration of some elements of the heat collecting plate. .

Before describing the assembling procedure, the configuration and the like of the photothermal hybrid module 10 will be described first. As shown in FIG. 12, the photothermal hybrid module 10 includes, in order from the front side, a white plate reinforced glass 102-an adhesive layer 104 made of an EVA (ethylene vinyl acetate) sheet-a solar cell element 101-an adhesive layer 104-a heat collecting plate 105. The structure is such that the layers are laminated and the periphery is sealed with a urethane resin 103. The configuration of the solar cell element 101 is a single crystal, a polycrystal,
Any structure such as amorphous may be used.
The material is not particularly limited as long as it satisfies functions such as Si and CdTe. The heat collecting plate 105 transmits solar heat to a heat medium flowing in the pipe to collect heat. The heat collecting plate 105 includes a panel 105a that receives heat from the sun and a water pipe 105c that is in heat conductive contact with the panel 105a. Have. Although not essential, a heat insulating material such as a urethane foam resin 105b is provided on the back surface of the panel 105a in order to improve the heat collecting performance. Functionally, the panel 105a is preferably made of metal, and particularly preferably made of aluminum in terms of lightness and rust prevention. In addition, when a selective absorption film or black coating is applied to the light receiving surface, the heat collecting performance is improved. The material of the water pipe 105c is preferably a metal in terms of function, and copper and aluminum are generally ideal in consideration of corrosion by a heat medium flowing inside.

FIG. 13 shows another configuration of the heat collecting plate 105.
As shown in FIG.
c is linearly high-frequency welded (the welded portion is indicated by H1), the linear welded portion is swaged by a press machine (the swaged portion is indicated by H2), and both ends of the water pipe 105c are made of a copper header pipe 4.
3 is brazed (the brazing point is indicated by H3). The front side of the panel 105a (the lower side in FIG. 13) is as flat as possible for attaching the solar cell element 101. In addition, although it is a matter related to the installation form, the water collecting pipe 105c has a better heat collecting performance when a path is taken so that the heat medium flows upward from the bottom due to buoyancy due to a temperature difference of the heat medium. .

As shown in FIG. 11, a cable 30 with connectors 31 and 32 for extracting electricity is drawn out from the back side of the photothermal hybrid module 10. In addition, in the place where the cable 30 is pulled out, FIG.
As shown in FIG. 2, a terminal box 106 is provided for protecting the soldered portion of the cable 30 and the lead wire from the solar cell element 101.

The procedure for manufacturing the photothermal hybrid module 10 is as follows. First, an EVA sheet (adhesive layer 104) is laid on a white plate reinforced glass 102, and a large number of single-crystal silicon solar cell elements 101 wired in series are placed on the EVA sheet. , And an EVA sheet (adhesive layer 104), heat collecting plate 1
05 is created from above. Next, it is laminated on a laminator device. Then, EV
The A sheet melts and the whole is adhered and integrated. The EVA that has melted and protruded to the periphery is cut, and the prepared one is set in a mold, and the surrounding urethane resin 103 for sealing is used.
Is formed by RIM molding. Thereafter, a foamable urethane resin 105b is sprayed on the surface on the side of the heat collecting plate 105 with a spray or the like to form a heat insulating layer on the back surface. Thus, the photothermal hybrid module 10 is obtained.

As the heat medium flowing through the water pipe, ethylene glycol, propylene glycol or the like often used as an antifreeze for automobiles can be used.

On the other hand, instead of the heat collecting plate 105 of the photothermal hybrid module 10, the solar cell module 11 arranged below the photothermal hybrid module 10 has a metal coated with PVF (vinyl fluoride resin) on both sides. You are using a sheet. The solar cell module 11
Since there is no need to form a heat insulating layer, the manufacturing method is almost the same as the manufacturing method of the photothermal hybrid module 10 except for the step of providing the heat insulating layer.

To obtain a roof panel P1 with a photothermal hybrid module as shown in FIG.
In the first assembly plant, the photothermal hybrid module 10 is fixed on the upper surface of the roof panel main body 1. Generally, a plurality of photothermal hybrid modules 10 are required, and a cable connection and a pipe connection between them must be performed. Therefore, these are also performed in a factory in advance. Also, depending on the desired amount of heat collection, not all modules on the roof panel P1 need to be photothermal hybrid modules. For this reason, in this embodiment, normal solar cell modules 11 are attached except for the required number. The solar cell module 11 only needs to be connected to a cable, and this is also performed in a factory in advance.

Next, referring to FIGS. 4, 5 and 6,
A procedure for attaching the two modules 10 and 11 to the roof panel main body 1 at the roof panel assembly factory to produce a roof panel P1 with a photothermal hybrid module will be described.
Here, as components of the frame 2 forming a lattice shape,
Various vertical and horizontal frame members are used.

A and 3B are stopped with screws 20 (see FIGS. 7 and 8). It is desirable to apply waterproofing treatment such as caulking to this screw stop portion. Next, the two modules 10 and 11 are fitted into predetermined locations while connecting the modules. As shown in FIG. 3 and the like, the fitting position is such that the upper horizontal row is the position of the photothermal hybrid module 10, and the lower horizontal rows are the position of the solar cell module 11.

The connection between the modules 10 and 11 is shown in FIG.
As shown in FIG. 8, the vertical frame members 2A and 2B (not shown), the horizontal frame members 3A (not shown) and 3B
The cable 30 from one module is passed through the cable through hole 31 opened on the side of the
2, 33 are inserted. After the fitting, it becomes as shown in FIG.

Further, since the photothermal hybrid modules 10 are arranged in a row on the upper side, the pipes of the adjacent modules must be connected. FIG. 10 shows how the upper header pipe (pipe) 43 is connected. The header tubes 43 of the adjacent modules 10 are connected to each other by a rubber hose (piping) 40, and in the connected state, both ends of the hose 40 are stopped by a hose band 42 so that the heat medium inside does not leak. In addition, since the hose 40 of the pipe connection portion straddles the lower vertical frame member, as shown in FIG. 9, the lower vertical frame members 2A and 2B are attached with a space provided therebetween, and the hose 40 is interposed between the lower vertical frame members 2A and 2B. I'm going to pass.

After the modules 10 and 11 have been fitted in this way, as shown in FIG. 5, the upper horizontal frame members 4A and 4B are put on predetermined positions, and the lower horizontal frame members 3A and 3B are placed on the lower horizontal frame members 3A and 3B. Stop with the screw 20 (see FIG. 8). Further, as shown in FIG. 6, the upper vertical frame members 5A, 5B and 5C are put on from above and the screws 20 screwed into the lower vertical frame members 2A, 2B and 2C (see FIG. 8).
Stop with This completes the mounting of both modules 10 and 11, and a roof panel P1 with a photothermal hybrid module as shown in FIG. 3 is completed.

In this case, the vertical frame members 2A, 2B, 2C, 5A, 5B, 5C, and the horizontal frame members 3A, 3B, 4A, 4B, which are the mounting frames, are made of extruded aluminum and are assembled. A groove 51 is formed as shown in FIGS. Therefore, modules 10, 11
The urethane resin 103 on the peripheral edge of the module is sandwiched between the upper and lower frame members while being fitted in the groove 51, and the modules 10 and 11 are securely fixed.

The above operation can be performed with the roof panel main body 1 placed on the ground or the floor surface in the factory, so that work at a high place can be avoided. Then, by using the roof panel P1 with the photothermal hybrid module manufactured as described above as a member constituting the roof surface of the unit house, the photothermal hybrid module can be automatically installed by mounting the roof panel P1. it can.
Further, in a house to which the roof panel P1 is attached, for example, by using the photothermal hybrid module 10 instead of the solar heat collector in the conventional solar water heater, not only power generation by the solar cell but also heat energy is utilized. be able to. In addition, by previously connecting cables and pipes at the factory, work on the roof at the construction site can be almost eliminated.
