Description

本発明は、太陽電池の裏面側に断熱材を配設してなる太陽電池複合パネルを用いて屋根構造として各種の建築物に適用できる太陽電池敷設構造に関する。 The present invention relates to a solar cell laying structure that can be applied to various buildings as a roof structure using a solar cell composite panel in which a heat insulating material is arranged on the back side of the solar cell.

従来、太陽電池を取り付けた屋根としては、種々の構造のものが知られており、各種の屋根構造に支持材や架台を介して太陽電池パネルを取り付ける構造と、例えば屋根板に太陽電池を一体化させて取り付ける構造とが知られているが、雨仕舞い性を屋根構造に依存する前者に比べ、後者はそれ自体に雨仕舞い性を有するので、全体厚みが薄くできる点で有利である。
後者に属する特許文献1は、凹凸状金属板(外囲板2)の表面に太陽電池(太陽電池モジュールパネル18)が取り付けられている構成である。また、この提案における凹凸状金属板の裏面凹部には、発泡ウレタンからなる下地層14が形成されている(充填されている)。
また、特許文献2に記載の太陽光発電ユニット10は、断熱層11と防水層12とソーラパネル13とが積層されたパネルである。
Conventionally, various structures are known for roofs on which solar cells are attached. However, compared to the former, which depends on the roof structure, the latter is advantageous in that the overall thickness can be reduced because the roof itself has the ability to keep rain out.
Patent Document 1, which belongs to the latter, has a configuration in which solar cells (solar cell module panel 18) are attached to the surface of an uneven metal plate (envelope plate 2). In addition, in this proposal, the recesses on the back surface of the uneven metal plate are formed (filled) with a base layer 14 made of urethane foam.
Moreover, the photovoltaic power generation unit 10 described in Patent Document 2 is a panel in which a heat insulating layer 11, a waterproof layer 12, and a solar panel 13 are laminated.

しかしながら、前記特許文献1では、凹凸状金属板(外囲板2)を全域に敷設することで「雨仕舞」を行い、その後に太陽電池(太陽電池モジュールパネル18)を敷設するものであって、作業効率が悪いものであった。
また、前記特許文献2では、太陽電池(ソーラパネル13)裏面が防水層12に密着しているため、自身が発生する熱量が放散されず滞留されるため、太陽電池の効率低下は避けられない構成である。しかもユニット同士の隣接部分は、防水テープ(図4)や突き合わせ(図12)によるものであって雨仕舞に大きな問題を有していた。
However, in Patent Literature 1, the uneven metal plate (enclosure plate 2) is laid over the entire area to "stop the rain", and then the solar cells (solar cell module panel 18) are laid. , work efficiency was poor.
In addition, in Patent Document 2, since the back surface of the solar cell (solar panel 13) is in close contact with the waterproof layer 12, the heat generated by itself is not dissipated and is retained, which inevitably reduces the efficiency of the solar cell. Configuration. In addition, adjacent parts of the units are made of waterproof tape (Fig. 4) or butted together (Fig. 12), which poses a serious problem in rain.

そこで、本発明は、太陽電池の裏面側に断熱材を配設してなる太陽電池複合パネルを用いて屋根構造として各種の建築物に適用できる太陽電池敷設構造を提案することを目的とする。 Accordingly, an object of the present invention is to propose a solar cell laying structure that can be applied to various buildings as a roof structure using a solar cell composite panel in which a heat insulating material is arranged on the back side of the solar cell.

本発明は、上記に鑑み提案されたものであって、太陽電池と少なくとも表面が非透水性である断熱材とが空間を隔てて一体化された太陽電池複合パネルが、太陽電池の表面が略平坦状になるように流れ方向及び流れ方向に交わる方向に敷設されることで、前記空間が連通状に形成され、両方向に隣り合う太陽電池複合パネルを形成する前記断熱材は、隣り合う前記断熱材の端縁同士が相決り状に重合されているか、或いは裏面に排水部材を配設して防水処理を施して前記断熱材の端縁同士が対向状に配設されていることで、防水状に接続されていることを特徴とする太陽電池敷設構造に関するものである。 The present invention has been proposed in view of the above, and provides a solar cell composite panel in which solar cells and a heat insulating material having at least a water-impermeable surface are integrated with a space therebetween. By laying flat in the flow direction and in a direction intersecting the flow direction, the space is formed in a communicating manner, and the heat insulating material forming the solar cell composite panels adjacent in both directions is the heat insulating material adjacent to the heat insulating material. The edges of the heat insulating material are overlapped with each other, or the edges of the heat insulating material are arranged opposite to each other by arranging a drainage member on the back surface for waterproofing. The present invention relates to a solar cell laying structure characterized by being connected in a shape.

本発明の太陽電池敷設構造は、太陽電池と少なくとも表面が非透水性である断熱材とが空間を隔てて一体化されているため、連通する空間により空気の流通が行われるので、太陽電池自体の発熱による効率低下を招くことがなく、また万が一太陽電池の裏面側に浸入した雨水や空間内にて結露した雨水等を非透水性である断熱材の表面にて流下させることができる。そのため、雨仕舞い性を備える屋根(下地)を必要としないので、全体厚みを薄く構築することができ、各種の太陽電池敷設構造に適用できる。
また、両方向に隣り合う太陽電池複合パネルを形成する前記断熱材は、隣り合う前記断熱材の端縁同士が相決り状に重合されているか、或いは裏面に排水部材を配設して防水処理を施して前記断熱材の端縁同士が対向状に配設されていることで、防水状に接続されているので、継続的に且つ物理的に雨仕舞いに優れたものとなる。
In the solar cell laying structure of the present invention, since the solar cell and the heat insulating material whose surface is at least impermeable to water are integrated with a space therebetween, air is circulated through the communicating space, so that the solar cell itself In addition, rainwater that has infiltrated the back side of the solar cell or condensed in the space can flow down on the surface of the non-permeable heat insulating material. Therefore, since a roof (substrate) having rain protection properties is not required, the overall thickness can be made thin, and it can be applied to various solar cell laying structures.
In addition, the heat insulating materials that form the solar cell composite panels adjacent to each other in both directions are formed such that the edges of the adjacent heat insulating materials are overlapped with each other, or waterproof treatment is performed by arranging a drainage member on the back surface. Since the edges of the heat insulating material are arranged facing each other, they are connected in a waterproof manner, so that they are continuously and physically excellent in rain protection.

また、両方向に隣接する太陽電池複合パネルは、隣り合う前記断熱材の端縁同士が相決り状に重合されているか、或いは裏面に排水部材を配設して防水処理を施して前記断熱材の端縁同士が対向状に配設されていることで、防水状に接続されている。

Since it is laid in the direction of flow and in a direction intersecting the direction of flow, a communicating space is formed to allow air to circulate . The direction crossing the flow direction corresponds to, for example, the girder direction of the gable roof.
In the solar cell composite panels adjacent in both directions, the edges of the adjacent heat insulating materials are overlapped with each other, or the back surface is provided with a drainage member and waterproofed so that the heat insulating materials are separated from each other. By arranging the edges facing each other, they are connected in a waterproof manner.

本発明に用いる太陽電池は、太陽電池モジュールとその周縁に取り付ける枠体とで形成されるものである。
前記太陽電池モジュールとしては、特にその構成及び形状を限定するものではなく、多結晶、単結晶、アモルファス等のシリコン系、化合物系、有機系などどのような太陽電池を用いてもよい。
また、前記枠体は、前記太陽電池モジュールの周縁に取り付けられて矩形状のパネルを形成するものであり、太陽電池モジュールの端縁を保持するために略コ字状(溝部を有する)であることが多いが、その構成は特に限定するものではない。
The solar cell used in the present invention is formed by a solar cell module and a frame attached to the periphery thereof.
The configuration and shape of the solar cell module are not particularly limited, and any solar cell such as silicon-based such as polycrystalline, single-crystal, or amorphous, compound-based, or organic-based may be used.
The frame is attached to the periphery of the solar cell module to form a rectangular panel, and has a substantially U-shape (having a groove) to hold the edge of the solar cell module. However, the configuration is not particularly limited.

本発明に用いる断熱材は、少なくとも表面が非透水性であれば、それ自体が非透水性の発泡樹脂で形成されるものでも、慣用的に断熱性能を有する材料の表面を非透水性の防水処理をしたものでもよいが、施工性を考慮すると軽量である発泡樹脂製(例えばEPS等)が好ましい。
この断熱材は、平板状であっても凹凸状であってもよい。また、この断熱材の表面は、浸入水等を円滑に流下、排出するための「溝」を有するものであってもよい。
さらに、この断熱材は、後述する第1実施例のように固定用の部材を固定部として一体的に備えるものでも良い。
As long as at least the surface of the heat insulating material used in the present invention is impermeable to water, even if the heat insulating material itself is formed of a water impermeable foamed resin, the surface of a material having heat insulating performance is conventionally treated as a water impermeable waterproof material. A treated one may be used, but considering workability, a lightweight foamed resin (for example, EPS, etc.) is preferable.
This heat insulating material may be flat or uneven. Moreover, the surface of this heat insulating material may have a "groove" for smoothly flowing down and discharging intruding water or the like.
Furthermore, the heat insulating material may be integrally provided with a fixing member as a fixing portion as in the first embodiment described later.

前記太陽電池と前記断熱材との間に形成される空間は、太陽電池裏面に形成され、隣接するパネル同士の空間が連通可能であれば、その形状を限定するものではない。また、この空間は、前記太陽電池と前記断熱材とが完全に離間するものでも、部分的に当接するものでもよい。 The space formed between the solar cells and the heat insulating material is not limited in shape as long as it is formed on the rear surface of the solar cells and the spaces between adjacent panels can be communicated with each other. In addition, this space may be one in which the solar cells and the heat insulating material are completely separated from each other, or in which they are partially in contact with each other.

そして、流れ方向とそれと交わる方向の両方向に隣接する太陽電池複合パネルは、防水状に接続されている。
この防水状の接続としては、隣接する端縁同士を重合状に接続する構成、或いは裏面に排水部材を配設して防水処理を施して接続する構成などの中から適宜に選択すればよい。
前者の態様、即ち断熱材の端縁に重合部、重合受部を形成する場合には、後述する図示実施例のように流れ方向の端縁、それと交わる方向の端縁のそれぞれに設けてもよいし、一方のみに設けてもよい。また、これらの重合部、重合受部は、単に重ねる(段差ができる)ものでも、相決り状(平坦状)であってもよく、空気流路としての機能を備えるものでもよいし、表面での排水を妨げなければ重合部分の態様は問わない。更に、重合と捨て板を併用してもよい。
後者の態様、即ち裏面に排水部材を配設して防水処理を施して接続する場合についても、公知の種々の防水構造を採用すればよい。
Adjacent solar cell composite panels in both the flow direction and the crossing direction are connected in a waterproof manner.
The watertight connection may be appropriately selected from among a configuration in which adjacent edges are connected in an overlapping manner, a configuration in which a drainage member is arranged on the back surface, and watertight treatment is applied to the connection.
In the former mode, that is, in the case of forming the overlapped portion and the overlapped portion at the edge of the heat insulating material, they may be provided at the edge in the direction of flow and the edge in the direction intersecting with it as in the illustrated embodiment described later. Alternatively, it may be provided only on one side. In addition, the polymerization portion and the polymerization receiving portion may be simply layered (to form a step), or may be in a phased (flat) shape, may have a function as an air flow path, or may have a surface The form of the polymerized portion does not matter as long as it does not interfere with the drainage of water. Furthermore, polymerization and a scrap board may be used in combination.
In the latter mode, that is, in the case where the back surface is provided with a drainage member and is connected after being waterproofed, various known waterproof structures may be employed.

前記太陽電池、前記断熱材、前記空間より形成される太陽電池複合パネルは、太陽電池と断熱材との一体化方法について特に限定するものではない。例えば接着等によるものでも、太陽電池の枠体を利用するものでも、別途取付具(固定具を兼用でもよい)等を用いるものでもよい。なお、ここでの一体化とは、パネルとして施工可能な態様であればよく、恒久的な一体を意味するものではない。 The solar cell composite panel formed from the solar cells, the heat insulating material, and the space is not particularly limited in the method of integrating the solar cells and the heat insulating material. For example, adhesion may be used, the frame of the solar cell may be used, or a separate fixture (which may also serve as a fixture) may be used. Note that integration here does not mean permanent integration, as long as it is a form that can be constructed as a panel.

前記太陽電池の枠体を利用して前記太陽電池と前記断熱材とを一体化する場合、断熱材は枠体の高さ内に収まる厚みであっても、枠体下部より下方に突出するものであってもよい。また、この太陽電池の枠体を用いて一体化する場合には、太陽電池は少なくとも対向する2辺に枠体を備えればよい。
また、前記断熱材は、太陽電池の端部に対してから延出状であっても、太陽電池に対して位相状でもよく、太陽電池と同等の大きさでも異なる大きさであってもよく、表面は雨水等の流下を円滑に行うために溝状部を設けてもよい。また、溝状部や相決りを採用する場合、円滑な流下を促すために下り傾斜状に形成してもよい。
When the solar cell frame is used to integrate the solar cell and the heat insulating material, the heat insulating material protrudes downward from the lower part of the frame even if the thickness of the heat insulating material is within the height of the frame. may be Moreover, when integrating using the frame of this solar cell, the solar cell should just have a frame on at least 2 sides which oppose.
In addition, the heat insulating material may extend from the end of the solar cell, or may be phase-shaped with respect to the solar cell, and may have a size equal to or different from that of the solar cell. , the surface may be provided with a groove-like portion for smooth flow of rainwater or the like. Moreover, when adopting a groove-shaped portion or a joint, it may be formed in a downward slope shape in order to promote smooth flow down.

以上の構成を有する本発明の太陽電池敷設構造は、太陽電池と断熱材とが空間を隔てて一体化されているため、連通する空間により太陽電池自体の発熱による効率低下を招くことがなく、また万が一太陽電池の裏面側に浸入した雨水や空間内にて結露した雨水等を断熱材の表面にて流下させることができる。また、そのため、雨仕舞い性を備える屋根(下地)を必要としないので、全体厚みを薄く構築することができる。 In the solar cell laying structure of the present invention having the above configuration, since the solar cells and the heat insulating material are integrated with a space therebetween, there is no reduction in efficiency due to heat generation of the solar cells themselves due to the communicating space. In addition, rainwater that has infiltrated the back side of the solar cell or rainwater that has condensed in the space can flow down on the surface of the heat insulating material. In addition, since a roof (base) having a rain-proof property is not required, the overall thickness can be reduced.
