Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combined solar heat / hot water power generation panel used in a detached house or other buildings, and a roof panel using the same.

[0002]

2. Description of the Related Art Conventionally, as a roof structure intended to utilize solar heat, there has been proposed a solar cell installed with a coil for obtaining hot water.

[0003]

However, since the structure is such that the solar cell and the coil for hot water are separately installed on site, there is a problem that installation of the solar cell and installation of piping are troublesome. In addition, there is a problem that the amount of heat that can be collected as hot water is small. As a simplification of construction, attempts have been made to develop a roof panel that uses a solar cell and a coil for hot water, but it was not satisfactory in terms of ease of panel production and heat recovery efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems, provide a solar heat / hot water supply power generation combined use panel which is easy to manufacture and has high heat recovery efficiency, and a roof panel using the same.

To use. According to this configuration, since the member serving as the flow path of the heat medium is provided on the back surface of the solar cell,
The thermal conductivity from the solar cell to the heat medium flow path is good, and the efficiency of heat recovery by generating hot water is good. Further, since it is a panel provided with a solar cell and a heat medium flow path, it is not necessary to perform piping work, and it is easy to manufacture a combined solar heat / hot water supply and power generation panel. In this configuration, the bottom surface of the heat collecting panel is made of heat insulating material.
Since the board has a laminated structure ,
The collected solar heat is prevented from escaping to the lower surface,
The heat recovery efficiency is high. This solar heat / hot water power generation combined use panel
When used as a roof panel component,
The board also improves the roof insulation. Also, thick
Since the positive battery is a layer laminated on a steel plate, its thickness is
A thin, high-strength plate-shaped product can be easily manufactured. these
Solar cells, heat collecting panels, and insulation boards are
Integrated solar power and hot water supply for mounting on the flannel frame
It can be handled as a combined panel and is easy to handle.

The member serving as the flow path of the heat medium may be a heat collecting panel having the flow path of the heat medium. That is,
The heat collecting panel having the flow path of the heat medium may be a combined solar heat / hot water supply / power generation panel laminated on the back surface of the plate-shaped solar cell. In this way, by providing the heat medium flow path on the heat collecting panel and stacking it on the back surface of the solar cell, the production of the combined solar heat / hot water supply power generation panel is simplified, and the heat medium flow path heat medium is also used. The efficiency of heat recovery is improved. In particular, it is preferable that the heat collecting panel has a heat medium passage therein. In this way, when the heat collecting panel itself has the flow path for the heat medium formed inside, since the heat collecting panel is adhered to the entire back surface of the solar cell, heat generated by hot water is generated. The collection efficiency will be even higher. That is, with a structure in which an independent coil (tube) is bonded to the back surface of the solar cell, the contact area between the coil for hot water and the solar cell is small, and it is difficult to obtain sufficient thermal conductivity. Therefore, the amount of heat that can be collected as hot water is small, even though the temperature of the solar cell surface is high. On the other hand, when the heat collection panel having the flow path of the heat medium inside is used, the heat recovery efficiency can be improved as described above. Further, since the heat collecting panel has a heat medium passage therein, it is not necessary to perform piping work, and the solar heat / hot water supply and power generation combined use panel can be manufactured more easily.

[0007] In solar-hot water generator together panels of these configurations may be attached to transparent plate via an air layer covers the upper surface of the solar cell laminate steel sheet to the panel frame. A transparent glass plate or the like can be used as the translucent plate. By thus providing the air layer through the translucent plate, the efficiency of heat collection can be further improved.

The solar heat / hot water supply / electric power generation combined use roof panel of the present invention is one in which the solar heat / hot water supply / electric power generation combined panel of any one of the above-mentioned configurations is mounted on the base plate. According to this configuration, by mounting the separately manufactured solar heat / hot water supply / generator combined panel on the base plate, a solar heat / hot water supply / generator combined roof panel can be easily manufactured. Installation work can be performed easily and inexpensively. In the roof panel for combined use of solar heat and hot water supply with the above configuration, a heat insulating material made of foamed resin may be provided on the lower surface of the base plate through an air layer, and the heat insulating material may be attached to the base plate through a base crosspiece. In the case of this structure, the heat insulating material can be provided on the lower surface side of the roof panel via the air layer with a simple structure in which the heat insulating material is simply attached via the base rail. By thus providing the air layer and the heat insulating material, it is possible to prevent the heat collected by the heat collecting panel from being radiated to the attic, so that the heat recovery efficiency is further improved and the heat is accumulated in the attic. Can be prevented.
