BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof with solar cells in which a plurality of solar panels are arranged on a roof base of a building.

[0002]

2. Description of the Related Art Conventionally, a solar cell is provided on a roof of a building such as a house in order to effectively utilize solar energy as electricity. A roof provided with solar cells is usually formed by arranging solar cell panels of a predetermined standard size vertically and horizontally on a roof base surface. The solar cell panel has a structure in which a frame member is attached to the periphery of a flat waterproof case containing a predetermined number of solar cells, and the frame member is attached to a support rail laid on a roof base surface. Kaihei 7-18310
No.). In such a roof, waterproofness is ensured by arranging solar cell panels as roofing materials side by side without gaps.

[0003]

In such a structure in which the solar cell panels are arranged without gaps, a top light cannot be formed on the roof, so that there is a problem that lighting from the ceiling into the building cannot be obtained. In order to solve such a problem, it is conceivable to provide a top light by omitting a part of the solar cell panel. However, since the solar cell panel is also a waterproof member constituting a waterproof structure of a roof, the solar panel is Omission of the battery panel causes a problem that the waterproof structure of the roof is complicated.

[0004] It is an object of the present invention to provide a roof with solar cells that can ensure lighting in a building without complicating the waterproof structure of the roof.

The present invention will be described with reference to the drawings. The present invention relates to a roof with solar cells 1 in which a plurality of solar cell panels 20 are arranged on a roof base surface 11 of a building. At least one of the battery panels is a light-transmitting panel 30 having the same outer shape as the solar cell panel and having a light-transmitting property, and a portion of the roof base surface corresponding to the light-transmitting panel has a top light 40. Is provided.

In the present invention, since the top light is provided on a portion of the roof base surface corresponding to the translucent panel disposed in place of the solar cell panel, the top light is provided via the translucent panel and the top light. You can light inside the building. In addition, since the translucent panel has the same outer shape as the solar cell panel, by arranging it on the roof base surface together with the solar cell panel, the same waterproof effect as when the solar cell panels are arranged can be obtained. Of the waterproof structure can be prevented. Further, since the translucent panel can be installed in the same manner as the solar cell panel, it can be easily constructed. And
The top light is covered by the translucent panel, and the exposed solar cell panel and the translucent panel receive wind pressure, so that wind pressure is not directly applied to the top light.
Therefore, since a low-strength material such as stained glass can be adopted as the light-transmitting member of the top light, a variety of top lights can be provided.

The solar cell panel includes a flat solar cell 21 for converting light into electric energy.
It is preferable that the light-transmitting panel is one in which the solar cell of this solar cell panel is made of a light-transmitting surface material 31 having a light-transmitting property. According to this configuration, the light-transmitting panel can be configured only by using the solar cell of the solar cell panel as the light-transmitting surface material, so that the light-transmitting panel can be easily formed.

[0008] The light-transmitting surface material is preferably made of tempered glass, whereby the strength of the light-transmitting panel can be further increased.

In the above, it is desirable that the top light is provided so as to protrude from the roof base surface. In this way, it is possible to adopt a waterproof structure that allows rainwater to flow around the top light along the roof base surface, so that the top light is recessed from the roof base surface and rainwater flows into the top light. As compared with the case, the waterproof structure can be simplified and rain can be easily made.

[0010] In the above, the solar cell panel and the translucent panel are supported by the support bar 13 provided on the roof base surface.
A ventilation path 50 is formed between the solar cell panel and the translucent panel and the roof base surface along the support bar, and the ventilation path is formed by the translucent panel and the top light. It is desirable to include the gap 40A formed between them.

As described above, by providing the ventilation path between the solar cell panel and the roof base surface, the solar cell can be cooled by the air flowing through the ventilation path, so that the energy conversion efficiency of the solar cell decreases due to a rise in temperature. Can be prevented. Furthermore, by providing a gap between the translucent panel and the top light and forming the ventilation path including the gap, the ventilation path is not blocked by the translucent panel and the top light. Therefore, since the cooling effect of the solar cell panel by the ventilation path can be secured, the energy conversion efficiency can be maintained at a high level.

The top light 40 is covered with the translucent panel 30 and receives the wind pressure from the exposed solar cell panel 20 and the translucent panel 30, so that the top light 40 is not directly applied with the wind pressure. Therefore, a low-strength material such as stained glass can be used for the glass 41A as the light-transmitting member of the top light 40, so that a variety of top lights 40 can be provided.

Further, since the light-transmitting panel 30 uses the solar cell 21 of the solar cell panel 20 as the light-transmitting surface material 31, it can be easily formed. Then, the light transmitting surface material 31
Is made of tempered glass, so that the light-transmitting panel 30 having excellent strength can be obtained.

The top light 40 is provided on the roof base surface 1.
Since it is provided so as to protrude from the roof 1, a waterproof structure is provided in which the rainwater flows around the top light 40 along the roof base surface 11, so that complicated waterproof treatment is not required. That is, the waterproof structure can be simplified and the rainfall can be easily made as compared with the case where the toplight is recessed from the roof base surface and rainwater flows over the toplight.

Since the air passage 50 is provided between the solar cell panel 20 and the roof base surface 11, the solar cell 21 can be cooled by the air flowing through the air passage 50, and the temperature of the solar cell 21 rises. Can be suppressed, and a decrease in the energy conversion efficiency of the solar cell 21 can be prevented. Further, a gap 40A is provided between the translucent panel 30 and the top light 40, and the ventilation path 50 is formed including the gap 40A. Therefore, the ventilation path 50 is blocked by the translucent panel 30 and the top light 40. Will not be done. Therefore,
Since the cooling effect of the solar cell 21 by the ventilation path 50 can be ensured, the energy conversion efficiency can be maintained high.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and also includes the following modifications.
That is, in the above-described embodiment, only one solar cell panel is replaced with a translucent panel. However, when a plurality of top lights are provided, or when a relatively large top light is provided, two or more solar cells are provided. The panel may be replaced with a translucent panel. In the above embodiment, a glass smaller than the light-transmitting panel 30 is used as the glass of the top light. However, a glass larger than the light-transmitting panel may be used. I just need. However, in order to secure sufficient lighting, it is preferable to make the light-transmitting surface material of the light-transmitting panel larger than the light-transmitting member of the top light.

In the above embodiment, the light-transmitting panel is formed by using the solar cell panel. However, the present invention is not limited to this. For example, the light-transmitting panel may be formed of only a light-transmitting surface material such as glass. Good.
