Heretofore, it has been practiced to install a plurality of solar cells on the roof of a building structure such as a house and supply power to the house from the solar cells to save energy. . [0003] By the way, solar cells are
If you heat yourself excessively, the energy conversion efficiency tends to decrease, so take measures to escape heat (radiation),
Means for surely preventing a decrease in energy conversion efficiency is required. [0004] Means for Solving the Problems The present invention has been made in order to achieve the above object, above the base panel spanned along the slope of the roof from the ridge side over the eaves side,
In a roof structure provided with a solar cell having a solar cell panel attached thereto, with a ventilation layer being provided between the base panel and the support member via the support member, the solar cell panel and the eaves top interval spaced between the tip, said support member extends to the eaves tip, over the extended portion of the eaves of the support material, the surface has eaves plate whitish is stretched, the vent layer On the ceiling surface of the eaves board
A heat insulating material is provided only on the lower surface . According to the present invention, heat is dissipated from the solar cell by the air flow that enters from the eaves and passes through the ventilation layer, so that the temperature rise is suppressed, and the energy conversion efficiency of the solar cell is always kept high. And stable power supply can be achieved. Since the surface of the eaves board attached to the eaves is a white color that hardly absorbs heat, the temperature rise of air entering the ventilation layer from the eaves is suppressed. The ceiling of the ventilation layer has a lower surface of the eaves plate.
Only the insulation is provided, so the heat on the eaves
It is insulated by the heat insulating material , transmission of heat to the air entering the ventilation layer is suppressed, and the effect of suppressing a temperature rise of the air flowing through the ventilation layer is promoted. And of such temperature rise
Suppressed air is applied to the solar panel that forms the ceiling of the ventilation layer.
Contact with the lower surface of the panel, which promotes heat dissipation from the solar panel
Is done . An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic cross section of a roof structure of a house to which an embodiment of the present invention is applied, which extends from a ridge M to an eaves N. Reference numeral 1 in FIG. 1 denotes a rectangular solar cell according to the present invention. With the attached roof panel 1, the roof panel 1 is fixed to a beam or the like in a state where its longitudinal direction is along the eaves N from the ridge M, and forms a roof Y. The roof panel 1 with solar cells is constructed by extending a plurality of solar cell panels 3 on a rectangular base panel 2. These solar cell panels 3 are:
A panel on which a number of solar cells 3a are arranged is supported by a lattice-shaped frame 4, and this frame 4 extends from a ridge M along an eaves N as shown in FIG. It is mounted on and fixed to the supporting member 14. The support member 14 forms a ventilation layer 5 extending from the eaves N to the ridge M between each solar cell panel 1 and the base panel. The ventilation layer 5 is in communication with a building ventilation hardware 6 constituting the building M. At the eaves N, as shown in FIG. 2, a space is provided between the solar cell panel 3 closest to the eaves N and the tip of the eaves N, and the entire length of the eaves N is located there. Insulation board (insulation material) 7
It extends obliquely downward from the lower end of the tip portion, and further has an upper eaves draining plate 8 stretched thereon. Therefore, the heat insulating board 7 is stretched on the lower surface of both the lower side of the front end portion of the frame 4 and the eaves draining plate 8, and as shown in FIG. Are located in A lower eaves drain board 9 is provided on the upper surface of the tip of the base panel 2 on the eaves N side. These draining plates 8 and 9 are bent further downward at the tips than the inclination of the roof Y, and the opening 10 faces the inside of a gutter 11 provided at the eaves N. The opening 10 is closed by a ventilation gallery 12 in which a number of ventilation holes are formed. The surface of the upper eaves draining plate 8 is painted in a white color that does not easily absorb heat. In the above-mentioned roof structure, the wind blowing outdoors flows from the ventilation holes of the ventilation gallery 12 provided at the eaves N into the building ventilation hardware 6 via the ventilation layer 5 of the roof panel 1,
From here it is discharged outside again. Heat is dissipated by the flow of the wind (air), and a rise in the temperature of the solar cell panel 3 is suppressed. As a result, the energy conversion efficiency of the solar cell is always kept high, and stable power supply is achieved.
In particular, in this case, the surface of the eaves draining plate 8 forming the surface of the eaves N is painted in a white color that is difficult to absorb heat, and the heat insulating board 7 therebelow acts. The effect of suppressing the temperature rise of the flowing air is promoted. [0014] [0015] As has been described in the foregoing, according to the roof structure with a solar cell of the present invention, above the base panel spanned along the slope of the roof from the ridge side over the eaves side A roof structure including a solar cell to which a solar cell panel is attached in a state in which a ventilation layer is provided between the base member and the support member via a support member, wherein the solar cell panel and the eaves The supporting material extends to the tip of the eaves, and a white eaves plate having a white surface is placed on the extension of the eaves of the supporting material, and the ventilation is provided. Below the eaves board on the ceiling of the layer
It is characterized by the fact that heat insulation is provided only on the surface, and since the surface of the eaves board attached to the eaves is a white color that is difficult to absorb heat, the temperature rise of the air entering the ventilation layer from the eaves is reduced. In addition, the ceiling of the ventilation layer is
Because only the surface is provided with insulation,
The heat is insulated by the heat insulating material, the transfer of heat to the air entering the ventilation layer is suppressed, and the effect of suppressing a rise in the temperature of the air flowing through the ventilation layer is promoted. And on such a temperature
The solar cell panel where the air whose rise is suppressed
As a result of contact with the lower surface of the
Is advanced . Therefore, the heat dissipation effect of the solar cell is improved, whereby the energy conversion efficiency of the solar cell is constantly maintained at a high level, and stable power supply can be achieved.
