A heat medium made of an antifreeze liquid such as ethylene glycol is sealed in the pipes 51 and 52. In this way, the photothermal hybrid panel 1 is attached to the roof unit 31 and, as shown in FIG. 11, forms a solar system together with a hot water tank 53 and a pump (not shown) installed on the ground. That is, the solar system of this example includes the photothermal hybrid panel 1 (heat collecting panel 12).

Next, the operation of this example will be described. As shown in the figure, in the photothermal hybrid panel 1 (heat collecting panel 12) exposed to the sun on the roof, the heat collector 12
1 is heated by sunlight S. The low-temperature heat medium supplied into the heat collector 121 from the inlet end by the forcible force of the pump is supplied to the heat collector 12 while passing through the internal pipe 122.
The heat is absorbed from the first and the temperature rises, becomes a high-temperature heat medium, and is sent from the outlet end to the hot water storage tank 53 on the ground via the pipe 52. Then, heat energy is given to the water obtained from the city water there. The heat medium that has become low temperature by this heat exchange is again pumped through the pipe 51 through the internal pipe 122.
To the photothermal hybrid panel 1 (heat collection panel 1

On the other hand, the water heated in the hot water storage tank 53 is stored heat not only during the day but also at night, and is supplied to the hot water supply facilities 61 and 62 in the kitchen and bathroom as needed.
In the cold season, it is also supplied to the hot water floor heating equipment 63 and used for reducing the hot water supply load and the heating heat load of the house.

According to the above configuration, the peripheral end of the photothermal hybrid panel 1 is sealed by the sealing member 13, and the sealing member 13 also has the function of the frame. It is possible to reduce the cost, and it is possible to manufacture easily at low cost. Further, since the sealing member 13 is made of resin, it is lightweight. Therefore, workability at the time of construction is good, and even when installing many on the roof surface,
There is no need to increase the building frame strength. Front mold 2a and back mold 2
b), the solar cell panel 11 and the heat collecting panel 12 are housed in a mold obtained by combining the casting part 2 with the casting part 2 formed around the peripheral end.
Since the urethane resin composition is poured into and solidified in 21, and integrally molded to manufacture the photothermal hybrid panel 1, the urethane resin composition enters all the fine concave portions of the casting part 221 and solidifies. After the molding, the solar cell panel 11 and the heat collecting panel 12 and the sealing member 13 are securely adhered to each other, and when the urethane resin composition enters into a fine concave portion and solidifies, the solar cell is formed by an anchor effect. It becomes difficult to separate the sealing member 13 from the panel 11 and the heat collecting panel 12.

Further, the main agent and the curing agent are mixed in the mixing head 24 to produce the urethane resin composition which is a two-part mixture curing type resin composition.
When poured into 21, since the urethane resin composition cures without heating, there is no need to provide a heating device,
Furthermore, since the time required in the heating step can be saved, the photothermal hybrid panel 1 can be manufactured more efficiently. In addition, since molding is possible with a small molding machine,
Capital investment can be reduced, which can contribute to lower costs. The sealing member 13 of the molded photothermal hybrid panel 1 has convex portions 13a, 1
3a,... Are fixed evenly when tightened from the outside with the mounting frame member, so that the solar cell panel 11 and the heat collecting panel 12 and the sealing member 13 are in close contact with each other. Can also be enhanced.

Therefore, the number of parts and man-hours can be reduced, and the manufacture can be easily performed at low cost.
Further, according to the configuration of the second aspect, since the sealing member also serves as the frame, it is not necessary to newly attach the frame, so that the manufacturing can be performed at low cost.

Further, according to the third aspect of the present invention, since the heat insulating panel suppresses the dissipation of heat from the heat collecting panel to the atmosphere, heat can be efficiently exchanged. According to the configuration of the fourth aspect, the photothermal hybrid panel main body is housed in a mold formed by combining the front mold and the back mold, and the cavity formed around the peripheral end of the photothermal hybrid panel main body. Then, the polymer sealing member composition is poured and solidified, and integrally molded to manufacture the photothermal hybrid panel. Therefore, the polymer sealing member composition is formed in all the fine concave portions of the cavity. And solidify and form. Therefore, the photothermal hybrid panel body is securely sealed, and, due to the anchor effect caused by the polymer sealing member composition penetrating into the fine concave portions and solidifying,
It is difficult to separate the sealing member that seals the photothermal hybrid panel main body from the photothermal hybrid panel main body. Further, the sealing member can be mounted at low cost.

According to the fifth aspect of the present invention, since the sealing member also functions as a heat insulating material, a photothermal hybrid panel having a heat insulating function can be obtained at low cost. According to the configuration of the sixth aspect, the photothermal hybrid panel main body is securely sealed, and a polymer sealing member having a predetermined thickness also serving as a heat insulating material is fixed to the back surface side. Therefore, in the obtained photothermal hybrid panel, heat dissipation from the heat collecting panel to the atmosphere is suppressed, and heat exchange between the heat collecting plate and the heat exchange fluid is performed efficiently. According to the configuration of the seventh aspect, the sealing member is made of resin or rubber, so that it is lightweight. Therefore, workability at the time of construction is good, and even when installing many on the roof surface,
There is no need to increase the building frame strength.

According to the eighth aspect of the present invention, the two-component mixed-curing type resin composition is produced by mixing the main agent and the curing agent, and if the resin composition is poured into the cavity, the resin composition can be heated without heating. Since the object is solidified, there is no need to provide a heating device, and the time required for the heating step can be saved, so that the photothermal hybrid panel can be manufactured more efficiently. In addition, since molding can be performed with a small molding machine, capital investment can be reduced, and this can be used for cost reduction. Further, since it is excellent in weather resistance and heat resistance, the reliability of the photothermal hybrid panel can be improved.
