Among them, the middle block on one end side in the length direction is the skylight part 8 and the other blocks are the sun blocks. A battery module (hereinafter abbreviated as module) 3 is installed.

The core material 6 is of two types: a vertical core material 6 a extending over both ends in the length direction of the roof panel body 2, and a horizontal core material 6 b arranged between the vertical core materials 6 a orthogonal to the vertical core material 6 a. The horizontal core member 6b is thinner than the vertical core member 6a, and the horizontal core member 6b is fixed to the vertical core member 6a so that the upper surfaces of both members are flush with each other. The horizontal core member 6b is slightly separated from the plywood 5 and is in a floating state. Note that, as shown in FIG. 3, only the horizontal core member 6b on the eaves P side has the same thickness as the vertical core member 6a.

The solar cell panel 3A includes the module 3 in which a plurality of solar cells 10 are arranged, and a frame-shaped frame 11 in which outer edges of the module 3 are fitted to support the solar cell module 3 and which are joined to each other. It consists of and.

In the module 3, a plurality of solar cells 10 each having a solar cell (not shown) built in a substantially square transparent plate 9 are formed in a rectangular shape by a joint (not shown) (in this case, 6 vertical pieces × It is a panel-shaped product that is composed of 4 sheets in total (24 sheets in total). A solar cell is an energy converter that uses a PN junction. For example, a P-type layer of 1-3 μ is formed on an N-type Si substrate so that light reaches the PN junction from the surface, and The one that utilizes the electromotive force effect is used.

The modules 3 are incorporated in the frame 11 having substantially the same outer dimensions as the roof panel body 2.

The frame 11 has a rectangular outer shape formed by a pair of a vertical outer frame 12 and a horizontal outer frame 13 extending vertically and horizontally, ie, in the direction of the roof inclination and in the direction orthogonal thereto, and the inside of these is formed. Further, inner frame members 14 extending in the vertical and horizontal directions are assembled in a lattice shape.

There are two types of inner frame members 14, a vertical member 14a extending from the eaves P to the ridge Q, and a horizontal member 14b which is disposed between the vertical members 14a orthogonally thereto and joined together. As shown in FIG. 6, a flat upper plate 16 having sealing materials 15 attached to both lower surfaces in the width direction and a sealing material 17 attached to both upper surfaces in the width direction to form a convex cross section as shown in FIG. It is composed of a plate 18 and a packing 19 sandwiched between the seal member 15 and the upper end of the lower plate 18, and the vertical members 14a and the horizontal members 14b are framed in a grid pattern corresponding to the blocks. . The horizontal outer frame 13 has basically the same structure as the vertical members 14a and the horizontal members 14b, except that the outer end face on which the module 3 is not fitted is formed flat. It is different from the material 14a and the horizontal material 14b.

Then, the lower plate 18 is fixed to the vertical core member 6a and the horizontal core member 6b of the roof panel main body 2 by nailing or the like, and then the edges of each module 3 (transparent plate 9 of the module 3) are attached to both sides. Each module 3 is fitted between the inner frame member 14 and the lateral outer frame 13 by sandwiching it between the base members 15 and 17 and connecting the upper plate 16 to the lower plate 18 by means such as screwing. . The sealing materials 15 and 17 and the packing 19 are preferably made of butyl rubber or the like.

The vertical outer frame 12 is joined to the vertical outer frames 12 of the roof panels 1 arranged next to each other. As shown in FIG. 7, the upper plate 20 and the lower plate having the same width as each other. The module 3 is sandwiched between the module 21 and the module 21 and fastened with screws 22 to support the module 3. Adjacent vertical outer frames 12 are joined to each other by a seal plate 24 that is attached by a screw 25 across the upper surface of the upper plate 20.

A frame 11 is formed by the vertical outer frame 12, the horizontal outer frame 13, and the inner outer frame 14, and each module 3 is fitted into the frame 11 as described above to form a solar battery panel 3A. .

The solar cell panel 3A and the roof panel body 2 have the same width, but the length of the solar cell panel 3A is one module 3 and the longer portion extends to the eaves P side. In this state, the solar cell panel 3A is attached to the upper surface of the roof panel body 2. As for the mounting method, a means for mounting the lower surface of the frame 11 on the vertical core member 6a and the horizontal core member 6b of the roof panel body 2 and fixing them by means of bonding or the like is adopted, whereby the roof panel 1 of this embodiment is mounted. Is configured.

In the roof panel 1, since the horizontal core member 6b is in a state of being slightly separated from the plywood 5 and floating as described above, the eaves tip is provided between the plywood 5 and the module 3. It has a ventilation layer 1A extending from the P side toward the ridge Q side. Further, the vertical core member 6a is also provided with notches (not shown) mainly for wiring, which connect the laterally adjacent ventilation layers 1A for each block.

Next, the skylight part 8 will be explained. As shown in FIGS. 2 and 3, the skylight part 8 extends to the eaves side where the solar cell panel 3A extends to the eaves side P. Instead of the module 3 described above, a transparent glass plate 30 (transparent panel) is fitted in the frame 11, and the block portion of the roof panel main body 2 below the glass plate 30 is formed. Are cut out to form an opening 2A. According to the skylight portion 8, sunlight passes through the glass plate 30 and allows the veranda B to receive solar radiation.

Now, in order to stretch the roof panel 1 having the above-mentioned configuration as a roof of a house, the length of one module 3 at the end portion on the eaves side P is made to extend outward from the outer wall or the like. As shown in FIGS. 4 and 5, the rafter 7 of the roof panel main body 2 is attached to the beam 28 provided above the ceiling constituted by the ceiling plate 27 made of gypsum board or the like stretched over the field edge 26. Together, fix both by means such as adhesion or nailing.

As shown in FIGS. 2 and 3, the rafter 7 is fixed to the small wall panel 40 at the portion having the veranda B, and the plywood 5 is provided at the end of the roof panel main body 2 on the eaves P side. A draining plate 41 is fitted over the rafter 7 and the eaves-edge metal fitting 42 is sandwiched between the horizontal member 14b of the frame 11 and the horizontal core member 6b of the roof panel body 2. Between the eaves metal 42 and the draining plate 41, a gallery 43 having a small hole for communicating the ventilation layer 1A of the roof panel 1 with the outside is fitted. Then, the outside air is configured to pass from the louver 43 to the ridge Q side through the ventilation layer 1A and be discharged to the outside from here.

In this way, the roof panels 1 are attached to a plurality of ceilings, and further, by adjoining the left and right adjacent roof panels 1 with the frame 11 between the seal plates 24 as described above, the roof of the house is Composed.

In the roof panel 1, the modules 3 are connected in series by the electric wires routed in the ventilation layer 1A, and a charging means (not shown) provided inside the house from the ridge Q side. ), And the electric power is supplied from this charging means by wiring indoors.

According to the roof configured by the roof panel 1 of the present embodiment having the above-described configuration, the skylight portion 8 is formed at the end of the roof panel 1 on the eaves P side, and the glass plate 3 of the skylight portion 8 is formed. Sunlight reaches the balcony B through 0. Therefore, it is possible to insolate the balcony B, which could not be achieved in the past, even during the daytime in summer.

Further, since the ventilation layer 1A is formed between the roof panel body 2 and the module 3, the heat of the module 3 is dissipated and the temperature rise is suppressed. Moreover, since the ventilation layer 1A extends from the eaves P to the ridge Q and extends along the slope thereof, an ascending air current is generated in the ventilation layer 1A from the eaves P to the ridge Q, and The air flow is more active due to the rising air flow, and thus the temperature rise of the module 3 is further suppressed. As a result, the energy conversion efficiency of the solar cell module 3 is always kept high, and stable power supply is achieved.

Further, the electric wires of each module 3 are wired in the ventilation layer 1A and are protected by the solar cell panel 3A and are not exposed to the outside, so that they are not directly affected by wind and rain or sunlight.

Further, since the ventilation layer 1A is connected from the eaves P to the ridge Q, the electric wire of the solar battery is connected when the roof panel 1 is assembled and pulled out to the end on the ridge Q side. If this is done, it is possible to pull out from the ventilation layer 1A to the building Q side at the time of construction and wire it indoors, so that it is not necessary to carry out the wiring work of the solar cell on the roof, and the construction is not troublesome.

In the above-mentioned embodiment, one roof window part 8 is formed in the center of the edge of the roof panel 1 on the eaves side P side. However, the number of roof windows 8 formed on the eaves side P side is the same. May be arbitrary, and for example, the entire edge of the eaves P side covering the balcony B may be the skylight 8.
