The temperature can be raised to enable hot water supply, or the working fluid of the heat pump can be circulated in the heat medium passage to be used for cooling and heating.

Moreover, since the photothermal hybrid panel 1 itself constitutes the headstock, it is possible to effectively utilize the parts of the building which have not been effectively utilized conventionally. It is ideal that the parapets and the like on which the photothermal hybrid panel 1 is arranged face north and south, but if it is not possible due to locational conditions, etc., the parapets may be placed on parts facing east and west. Fully effective. At this time, if the inclination angle of the light receiving surface portion 5 is relatively low, light can be received in a wide range. Further, a parapet or the like having no photothermal hybrid panel 1 may be provided with a headboard having the same appearance, so that the design can be unified.

The present invention has been described above with reference to the embodiments shown in the drawings, but the present invention is not limited to the above-mentioned embodiments, and can be carried out as appropriate unless the construction described in the scope of claims for utility model is changed. For example, a larger number of spaces may be formed and different heat mediums may be passed through the spaces, or a heat insulating layer may be formed with the first space immediately on the back surface side of the solar cell as an air layer.

[0021]

According to the photothermal hybrid panel of the present invention, the solar energy is converted into electric energy by the solar cell and is also used as the heat energy by the heat medium, so that the overall energy efficiency is notably improved. Instead, it is arranged at the top of a building, such as a parapet, which has the highest amount of solar radiation, so it can receive sufficient sunlight. Further, since the light-heat hybrid panel itself can form the headstock, it is possible to effectively utilize the unused portion of the building which could not be used in the past, which is extremely high in practical value. Further, the present invention has a simple structure, is easy to handle, and can be provided at a low cost.
