DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof slab to which a solar member is mounted, in particular to make the solar illuminating efficiency of the mounted solar member extremely good and to minimize the adhesion of dirt. The present invention relates to a solar roof slab and a solar roof which are less likely to be damaged.

2. Description of the Related Art In recent years, various types of shingles equipped with solar members have been developed, and construction of roofs using the shingles is expanding. In many of them, a sheet-like solar member is attached to a flat portion having the largest area of a roof shingle. Thereby, a solar member having a large area can be formed, and a large amount of sunlight can be received.

[0003]

By the way, as described above, by applying a sheet-like solar member to a flat portion having the widest area of a roof plate, it is possible to receive much sunlight. However, in the case of a folded plate type in which peaks and valleys are alternately continuous, the peaks and connecting portions hinder sunlight, and the effective irradiation area of the solar member may decrease. Furthermore, on the wide flat surface, garbage such as dead leaves,
Dust and the like of sand and the like uniformly and evenly cover, and in such a state, a substantial irradiation area decreases and the sunlight irradiation efficiency also decreases.

Further, since the irradiation angle of the sunlight changes every moment due to the movement of the sun due to the change of time, as described above, the bulging chevron portion which is engaged in the fitting prevents the sunlight from irradiating the solar member with time. Or the amount of power generation varies depending on the amount of sunlight irradiation with time.

[0005]

The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that the present invention is directed to one side in the width direction of a valley-shaped arc-shaped main plate having a flat U-shaped cross section. Forming a non-solar fitted portion at one end, and forming a non-solar fitted portion fitted to the non-solar fitted portion at the other end;
By providing a solar roof plate and a solar roof in which a sheet-like solar member is mounted on the upper surface of the valley-shaped arc-shaped main plate, the solar irradiation efficiency on the solar member is extremely improved, and the adhesion of dirt is improved. The above problem can be prevented as much as possible, and the solar member can be hardly damaged.

The non-solar fitting portions 3 of the solar roof panels A adjacent to each other are fitted in an overlapping manner, so that the adjacent solar roof panels A, A can be fitted and connected to each other (see FIG. 5).

Next, as shown in FIG. 2, the solar member 4 mounted on the valley-shaped arc-shaped main plate 1 has a sheet shape.
It is stuck on the surface (upper surface) of the valley-shaped arc-shaped main plate 1. Further, the solar member 4 is formed by assembling a plurality of sheet-like plate pieces, performing an electrical coupling process, forming a long rectangular shape in the longitudinal direction, and extending along the longitudinal direction of the valley-shaped arc-shaped main plate 1. Then, the solar member 4 is attached (see FIG. 4).

The solar member 4 has a flat solar cell element sealed in an EVA resin, and the front side of the EVA resin is coated with a fluorine resin film. In particular, the solar member 4 includes the valley-shaped arc-shaped main plate 1.
Are attached at an intermediate position, leaving both sides in the width direction. Then, the width direction of the valley-shaped arc-shaped main plate 1 and the solar member 4 has substantially the same arc shape (see FIG. 3).

Next, the non-solar fitting portion 3 of another solar roof plate A adjacent to the solar roof plate A is placed on the non-solar fitted portion 2 of the solar roof plate A at the front position, and is pushed in as it is. Fit. This is repeated sequentially to construct a solar roof.

[0017]

According to the first aspect of the present invention, a non-solar fitted portion 2 is formed at one end in the width direction of a valley-shaped arc-shaped main plate 1 having a flat U-shaped cross section, and the non-solar fitted portion is formed at the other end. By forming a non-solar fitting part 3 to be fitted to the fitting part 2 and forming a solar roof panel A in which a sheet-like solar member 4 is mounted on the upper surface of the valley-shaped arc-shaped main plate 1, First, dirt and dust can be hardly adhered to the solar member 4 over the entire surface, and a decrease in power generation can be prevented. Second, the effective irradiation area of the solar member 4 with sunlight can be increased. Thirdly, the amount of power generation can be made less likely to fluctuate due to changes in the irradiation angle of sunlight with the passage of time. Seeds that can be used as a scaffold and make the solar member 4 more difficult to damage Achieve the effect.

The above effect will be described in detail. In the solar roof panel A of the present invention, since the valley-shaped arc-shaped main plate 1 has a U-shaped cross-section in the width direction, it is mounted on the valley-shaped arc-shaped main plate 1. The solar member 4 is formed in substantially the same arc shape along the width direction of the valley-shaped arc-shaped main plate 1.

For this purpose, the sheet-like solar member 4 has an arc shape in the width direction similarly to the valley-shaped arc-shaped main plate 1, and therefore, the solar member 4 having the arc shape in the width direction adheres to the surface thereof. It is easy for dust and dirt to collect at the lowest position in the width direction in the shape of a circular arc, and it is possible to reduce as much as possible the hindrance of sunlight irradiation due to dirt and dust,
Further, the dust and the like gathered at the lowest position of the sheet-like solar member 4 can be washed away at a stroke by the flow of rainwater concentrated on the bottom portion, and the good sun again It can be irradiated with light. These have the advantage that the solar radiation rate can be increased over a long period. [FIG. 8 (A), (B)
reference〕.

Next, when the cross section in the width direction is inverted trapezoidal like a roof plate seen in a general type, the width L _O of the flat main plate becomes narrow, and accordingly, the sheet-like solar The area for mounting the member 4 was also small and limited (see the two-dot chain line in FIG. 3). In contrast,
In the present invention, the width dimension L _N along the arc-shaped surface in the width direction of the valley-shaped arc-shaped main plate 1 has no corner portion because the cross-sectional shape is a flat concave arc shape in the width direction. The sheet-shaped solar member 4 can be mounted up to the same size as the width direction of the valley-shaped arc-shaped main plate 1 (see the solid line portion in FIG. 3). Therefore, the solar member 4
Can receive a sufficiently large effective irradiation area of sunlight by being attached to the valley-shaped arc-shaped main plate 1.

Next, since the width direction of the solar member 4 is mounted along the width direction of the trough-shaped arc-shaped main plate 1, the solar member 4 has an arc shape in the width direction like the trough-shaped arc-shaped main plate 1. Therefore, even if the sun moves with the passage of time, the solar member 4 can receive the entire surface of the sun, and the power generation amount fluctuates due to the change in the irradiation angle of the sun. Can be extremely reduced, a decrease in the amount of power generation can be prevented, and a highly efficient power generation can always be obtained (see FIG. 7). Further, in the present invention, the solar roof shingle A is used as a roof shingle constituting a roof. However, it is needless to say that the solar roof shingle A can also be used as an inclined wall.

Next, according to a second aspect of the present invention, in the first aspect, the valley-shaped arc-shaped main plate 1 is a solar roof shingle A in which the center in the width direction is the lowest position. The dust, dirt, and the like adhering to the solar member 4 having an arc shape substantially the same as the width direction of 1 can be always concentrated substantially at the center of the solar member 4 in the width direction, and the dirt and dust can be removed very easily. And the solar radiation rate can be increased over a long period of time.

Next, a third aspect of the present invention is directed to the first or second aspect.
, A plurality of trough-shaped arc-shaped main plates 1 and 1 are provided between the non-solar fitted portion 2 and the non-solar-fitted portion 3, and a non-solar Since the solar roof panel A is formed by forming the bulging portion 1a, one solar roof panel A has a plurality of valley-shaped arc-shaped main plates 1, 1, ... and a non-solar bulging portion 1a therein. Therefore, only one solar roof shingle A has a plurality of solar roof shingles A, A, A having only one valley-shaped arc-shaped main plate 1.
… Can greatly reduce the roof construction time.

A non-solar fitting portion 2 is formed at one end in the width direction of the valley-shaped arc-shaped main plate 1 having a flat U-shaped section, and the non-solar covering portion is formed at the other end. A non-solar fitting portion 3 fitted to the fitting portion 2 is formed, and a sheet-like solar member 4 is attached to the valley-shaped arc-shaped main plate 1 to form a solar roof plate A. The non-solar fitting of the solar roof panel A adjacent to the non-solar fitting section 2 of the front solar roof panel A is performed by fitting the solar fitting section 2 onto the metal fitting 8 fixed to the structural material 7. The non-solar fitted part 2 and the non-solar fitting part 3 do not have the solar member 4 because the joint part 3 is fitted and the solar roof is constructed by sequentially repeating this. At the time of construction, the solar roof shingles A adjacent in the width direction The worker can work while walking at the joint portion between the non-solar fitted portion 2 and the non-solar fitted portion 3, and after completion, the non-solar fitted portion 2 and the non-solar Inspection work can be performed while walking at the joint by the fitting portion 3.

Further, it is possible to make it difficult for dust and dirt to adhere to the entire surface of the solar member 4 having a valley-shaped arc shape, to prevent a decrease in the amount of power generation, and to prevent the solar member 4 The effective irradiation area of light can be widened, and the amount of power generation can hardly fluctuate due to a change in the irradiation angle of sunlight with the passage of time.
