Description

本発明は、太陽電池モジュールを備えた屋根構造及び建築物並びに瓦に関する。   The present invention relates to a roof structure, a building, and a tile provided with a solar cell module.

近年、化石燃料の枯渇、地球温暖化などの資源・地球環境問題への関心が高まり、クリーンで無尽蔵のエネルギー資源である太陽光、風力、地熱といった自然エネルギーを利用する技術が大きな注目を集めている。特に、無限に降り注ぐクリーンな太陽の光エネルギーを電気エネルギーに変換する太陽光発電が大きな期待を集めており、屋根に複数の太陽電池モジュールを並べて設置し、家庭での電力を太陽光発電で賄うようにした住宅が増大している。   In recent years, interest in resources and global environmental issues such as fossil fuel depletion and global warming has increased, and technologies that use natural energy such as solar, wind, and geothermal, which are clean and inexhaustible energy resources, have attracted a great deal of attention. Yes. In particular, solar power generation that converts infinitely clean solar light energy into electrical energy is attracting great expectations, and multiple solar cell modules are installed side by side on the roof to provide household electricity with solar power generation. The number of such houses has increased.

一方、従来、住宅の屋根（建築物の屋根（屋上含む））に太陽電池モジュールを設置して発電を行う太陽光発電システムでは、例えば、屋根に複数の架台をアンカーボルト等で固定し、これら架台に複数の太陽電池モジュールを取り付けて設置している（例えば、特許文献１参照）。   On the other hand, conventionally, in a photovoltaic power generation system that generates power by installing a solar cell module on a roof of a house (including a roof of a building (including a rooftop)), for example, a plurality of mounts are fixed to the roof with anchor bolts, etc. A plurality of solar cell modules are attached and installed on the gantry (see, for example, Patent Document 1).

特開平１０−２１９９５０号公報JP-A-10-219950

しかしながら、上記従来の太陽光発電システムにおいては、住宅の屋根に架台を固定するためのアンカーボルト等が必要になり、住宅の屋根に孔をあけることになる。また、複数の太陽電池モジュールで発電した電力を住宅の各部に供給するため、住宅の屋根や壁、床等に孔をあけ、この孔に通して複数の太陽電池モジュールに接続した電線を住宅の外部から内部に引き込むようにしている。なお、このとき、孔の隙間はコーキングで埋める。あるいは、火災時の延焼を防止するため、金属管等の耐火材を孔に挿通して設置し、この耐火材に電線を通すようにし、さらに隙間を耐火剤でコーキングする。   However, in the conventional solar power generation system described above, an anchor bolt or the like for fixing the mount to the roof of the house is required, and a hole is made in the roof of the house. Also, in order to supply the power generated by multiple solar cell modules to each part of the house, holes are made in the roof, walls, floors, etc. of the house, and electric wires connected to the multiple solar cell modules through these holes are connected to the house. I try to pull it in from the outside. At this time, the gap between the holes is filled with caulking. Alternatively, in order to prevent the spread of fire in the event of a fire, a refractory material such as a metal tube is inserted through the hole, an electric wire is passed through the refractory material, and the gap is coked with a refractory agent.

このため、屋根や壁等に孔をあけることにより、気密性、防水性、防火性が低下し、空気漏れや雨水の浸入等を招くおそれがある。また、躯体の耐久性が低下し、雨水の浸入、腐食、汚れの付着等を誘発するおそれもある。さらに、電線が露出することで外観を損なう場合があった。さらに、金属管等の耐火材やコーキングの耐火剤が必要になり、材料費、施工費が増大する。   For this reason, by making a hole in a roof, a wall or the like, airtightness, waterproofness, and fireproofness are lowered, and there is a risk of causing air leakage, intrusion of rainwater, and the like. In addition, the durability of the housing is lowered, and there is a risk of intrusion of rainwater, corrosion, adhesion of dirt, and the like. Furthermore, the external appearance may be impaired by exposing the electric wire. Furthermore, refractory materials such as metal pipes and caulking refractory agents are required, which increases material costs and construction costs.

特に、住宅のリフォームを行う際など、既存の建築物に太陽光発電システムを新たに設置する場合には、屋根や壁に孔をあけることが必要になり、上記のような問題が発生しやすい。   In particular, when installing a new solar power generation system in an existing building, such as when renovating a house, it is necessary to make holes in the roof and walls, and the above problems are likely to occur. .

上記の課題を解決するために、この発明は以下の手段を提供している。   In order to solve the above problems, the present invention provides the following means.

請求項１記載の屋根構造は、屋根の上面に配置された太陽電池モジュールと、前記太陽電池モジュールに接続して設けられた送電コイルと、前記太陽電池モジュールが発電して前記送電コイルに電流が流れると、前記送電コイルと共鳴して磁界を発生させ、前記太陽電池モジュールで発電した電力を受電する受電コイルとを備えていることを特徴とする。
なお、本発明に係る「屋根」は、例えば瓦屋根、折板屋根、ビルのような平面状の屋上（屋根）など、建築物の屋根に相当するものすべてを含む。 The roof structure according to claim 1, a solar cell module disposed on an upper surface of the roof, a power transmission coil connected to the solar cell module, and the solar cell module generates power to generate current in the power transmission coil.

It should be noted that the “roof” according to the present invention includes all those corresponding to the roof of a building, such as a tile roof, a folded plate roof, and a flat rooftop (roof) like a building.

請求項２記載の屋根構造は、請求項１記載の屋根構造において、前記太陽電池モジュールと前記送電コイルが瓦に一体に設けられていることを特徴とする。
なお、本発明に係る「前記太陽電池モジュールと前記送電コイルが瓦に一体に設けられている」とは、従来の瓦に太陽電池モジュールや送電コイルを取り付けた状態や、太陽電池モジュールや送電コイルを一体形成した瓦一体型太陽電池の状態を含む。 A roof structure according to a second aspect is the roof structure according to the first aspect, wherein the solar cell module and the power transmission coil are integrally provided on a tile.
Note that “the solar cell module and the power transmission coil are integrally provided on the roof tile” according to the present invention means that the solar cell module or power transmission coil is attached to a conventional roof tile, or the solar cell module or power transmission coil. Including a state of a roof tile-integrated solar battery in which is integrally formed.

請求項３記載の建築物は、請求項１または請求項２に記載の屋根構造と、前記受電コイルに接続されたパワーコンディショナーとを備えていることを特徴とする。   A building according to a third aspect includes the roof structure according to the first or second aspect and a power conditioner connected to the power receiving coil.

請求項４記載の瓦は、太陽電池モジュールと、前記太陽電池モジュールに接続して設けられた送電コイルとを一体に備えて形成されていることを特徴とする。   The roof tile according to claim 4 is formed by integrally including a solar cell module and a power transmission coil connected to the solar cell module.

請求項１記載の屋根構造においては、屋根に配置された太陽電池モジュールで発電した電力によって送電コイルに電流が流れることにより、送電コイルと受電コイルの間の磁界が振動し、送電コイルと受電コイルの間で共鳴現象が生じる。そして、このように共鳴現象を発生させると、送電コイルと受電コイルの間に発生する磁界を介して、送電コイルから受電コイルに太陽電池モジュールで発電した電力を供給することができる。   In the roof structure according to claim 1, when a current flows through the power transmission coil by the power generated by the solar cell module disposed on the roof, the magnetic field between the power transmission coil and the power reception coil vibrates, and the power transmission coil and the power reception coil A resonance phenomenon occurs between the two. When the resonance phenomenon is generated in this way, the power generated by the solar cell module can be supplied from the power transmission coil to the power reception coil via the magnetic field generated between the power transmission coil and the power reception coil.

すなわち、受電コイルを建築物の内部（屋内側）に設け、太陽電池モジュールで発電した電力を磁界共鳴式の非接触給電システムによって建築物の内部の各部に供給することができ、従来の太陽光発電システムのように、屋根や壁等に孔をあけて太陽電池モジュールから電線を建築物の内部に引き込むことを不要にできる。   That is, the power receiving coil is provided inside the building (inside the building), and the electric power generated by the solar cell module can be supplied to each part of the building by the magnetic resonance type non-contact power feeding system. Like a power generation system, it is possible to eliminate the need to make holes in the roof, walls, and the like and draw the electric wires from the solar cell module into the building.

これにより、従来のように屋根や壁等に孔をあけて気密性、防水性、防火性、躯体の耐久性を低下させることなく、住宅等の建築物の内部に太陽電池モジュールで発電した電力を供給することが可能になる。また、電線によって外観を悪化させることを解消でき、さらに、金属管等の耐火材やコーキングの耐火剤が不要になるため、材料費、施工費の低減を図ることも可能になる。   As a result, electric power generated by solar cell modules inside buildings such as houses without lowering airtightness, waterproofness, fireproofness, and durability of the housing by making holes in roofs and walls as in the past Can be supplied. In addition, it is possible to eliminate the deterioration of the external appearance due to the electric wire, and further, it becomes possible to reduce the material cost and the construction cost because a refractory material such as a metal pipe and a refractory agent for caulking are unnecessary.

請求項２記載の屋根構造においては、太陽電池モジュールを瓦の上面側に、送電コイルを太陽電池モジュールに接続しつつ瓦の上面側又は下面側に一体に設けて瓦を形成し、この瓦を用いることによって、屋根に太陽電池モジュールを支持するための架台を設ける必要がなくなる。これにより、外観の向上を図ることができ、且つこの瓦を設置してゆくだけで容易に太陽光発電システムを構築することが可能になる。また、屋根に架台を固定するための孔を設ける必要がないため、この点からも、気密性、防水性、防火性、躯体の耐久性を低下させることなく、住宅等の建築物の内部に太陽電池モジュールで発電した電力を供給することが可能になる。   In the roof structure according to claim 2, the solar cell module is integrally provided on the upper surface side or the lower surface side of the tile while the solar cell module is connected to the upper surface side of the tile and the power transmission coil is connected to the solar cell module. By using it, it becomes unnecessary to provide a mount for supporting the solar cell module on the roof. As a result, the appearance can be improved, and a solar power generation system can be easily constructed simply by installing the roof tile. Moreover, since there is no need to provide a hole for fixing the frame to the roof, it is possible to prevent the airtightness, waterproofness, fireproofing, and durability of the housing from being reduced. It becomes possible to supply electric power generated by the solar cell module.

請求項３記載の建築物においては、太陽電池モジュールで発電し、送電コイルから受電コイルに供給された直流の電力をパワーコンディショナーで交流に変換して建築物の各部に供給できる。   In the building of Claim 3, it can generate | occur | produce with a solar cell module, can convert the direct-current electric power supplied to the receiving coil from the power transmission coil into alternating current with a power conditioner, and can supply it to each part of a building.

請求項４記載の瓦においては、太陽電池モジュールを上面側に、送電コイルを太陽電池モジュールに接続しつつ上面側又は下面側に一体に設けて瓦を形成する。そして、この瓦を用いることによって、屋根に太陽電池モジュールを支持するための架台を設ける必要がなくなり、外観の向上を図ることができ、且つこの瓦を設置してゆくだけで容易に太陽光発電システムを構築することが可能になる。また、屋根に架台を固定するための孔を設ける必要がないため、気密性、防水性、防火性、躯体の耐久性を低下させることなく、住宅等の建築物の内部に太陽電池モジュールで発電した電力を供給することが可能になる。   In the roof tile according to claim 4, the roof is formed by integrally providing the solar cell module on the upper surface side and connecting the power transmission coil to the solar cell module on the upper surface side or the lower surface side. By using this tile, it is not necessary to provide a stand for supporting the solar cell module on the roof, the appearance can be improved, and solar power generation can be easily performed simply by installing this tile. It becomes possible to build a system. In addition, since it is not necessary to provide a hole for fixing the mount to the roof, it is possible to generate electricity with a solar cell module inside a building such as a house without reducing the airtightness, waterproofness, fireproofing, and durability of the housing. Power can be supplied.

以下、図１から図３を参照し、本発明の一実施形態に係る屋根構造及びこれを備えた建築物並びに瓦について説明する。   Hereinafter, with reference to FIGS. 1-3, the roof structure which concerns on one Embodiment of this invention, the building provided with this, and a tile are demonstrated.

図１に示すように、本実施形態の建築物Ａは、住宅等であり、太陽光発電システム１を備えている。また、太陽光発電システム１は、図１から図３に示すように、建築物Ａの屋根Ａ１の上（屋上含む）に配置される太陽電池モジュール２と、磁界共鳴式の非接触給電システム３と、パワーコンディショナー４とを備えて構成されている。さらに、磁界共鳴式の非接触給電システム３は、太陽電池モジュール２に接続して設けられた送電コイル（送電側デバイス、磁界発生器）５と、太陽電池モジュール２が発電して送電コイル５に電流が流れると、送電コイル５と共鳴して磁界を発生させ、太陽電池モジュール２で発電した電力を受電する受電コイル（受電側デバイス）６とを備えている。   As shown in FIG. 1, the building A of the present embodiment is a house or the like and includes a solar power generation system 1. Further, as shown in FIGS. 1 to 3, the solar power generation system 1 includes a solar cell module 2 disposed on a roof A1 (including a rooftop) of a building A, and a magnetic resonance type non-contact power feeding system 3. And a power conditioner 4. Further, the magnetic resonance type non-contact power feeding system 3 includes a power transmission coil (power transmission side device, magnetic field generator) 5 provided connected to the solar cell module 2, and a power generation by the solar cell module 2 to the power transmission coil 5. When a current flows, it includes a power receiving coil (power receiving side device) 6 that resonates with the power transmitting coil 5 to generate a magnetic field and receives power generated by the solar cell module 2.

そして、本実施形態の建築物Ａの屋根構造Ａ２は、野地板７の上に防水シート８を敷設し、さらに防水シート８の上に瓦９を敷設して構成されている。また、この屋根構造Ａ２に、太陽電池モジュール２と、磁界共鳴式の非接触給電システム３とが具備され、本実施形態では、瓦９が、その上面側に太陽電池モジュール２を一体に設け、下面側に送電コイル５を太陽電池モジュール２に接続しつつ一体に設けて形成されている。   And the roof structure A2 of the building A of this embodiment is constructed by laying a waterproof sheet 8 on the field board 7 and further laying a tile 9 on the waterproof sheet 8. In addition, the roof structure A2 includes the solar cell module 2 and the magnetic resonance type non-contact power feeding system 3. In this embodiment, the roof tile 9 is integrally provided with the solar cell module 2 on the upper surface side. The power transmission coil 5 is integrally formed on the lower surface side while being connected to the solar cell module 2.

また、受電コイル６は、屋根構造Ａ２よりも建築物Ａの屋内側に設けられ、パワーコンディショナー４に配線で接続されている。さらに、パワーコンディショナー４に屋内配線が接続されている。   The power receiving coil 6 is provided on the indoor side of the building A with respect to the roof structure A2 and is connected to the power conditioner 4 by wiring. Furthermore, an indoor wiring is connected to the power conditioner 4.

上記のように構成した本実施形態の太陽光発電システム１では、屋根Ａ１に配置された瓦９の上面側に設けた太陽電池モジュール２に太陽光が照射されると、この太陽電池モジュール２によって太陽光エネルギーが電気エネルギーに変換される。このように太陽電池モジュール２で発電が行われると、太陽電池モジュール２から発電した電力が送電コイル５に送電される。   In the solar power generation system 1 of the present embodiment configured as described above, when sunlight is irradiated to the solar cell module 2 provided on the upper surface side of the roof tile 9 arranged on the roof A1, the solar cell module 2 Solar energy is converted to electrical energy. When power is generated by the solar cell module 2 in this way, the power generated from the solar cell module 2 is transmitted to the power transmission coil 5.

そして、送電コイル５に共振周波数と同一の周波数の電流が流れると、送電コイル５と受電コイル６の間の磁界が振動し、送電コイル５と受電コイル６の間で共鳴現象が生じる。このように共鳴現象を発生させると、送電コイル５と受電コイル６の間に発生する磁界を介して、送電コイル５から受電コイル６に太陽電池モジュール２で発電した電力が給電される。なお、「同一の共振周波数」とは、完全な同一に限らず、実質的に同一という意味である。   When a current having the same frequency as the resonance frequency flows through the power transmission coil 5, the magnetic field between the power transmission coil 5 and the power reception coil 6 vibrates and a resonance phenomenon occurs between the power transmission coil 5 and the power reception coil 6. When the resonance phenomenon is generated in this way, the electric power generated by the solar cell module 2 is supplied from the power transmission coil 5 to the power reception coil 6 via the magnetic field generated between the power transmission coil 5 and the power reception coil 6. The “same resonance frequency” is not limited to completely the same, but means substantially the same.

このようにして受電コイル６で受電した電力は、パワーコンディショナー４で直流から交流に変換され、屋内配線によって建築物Ａの屋内の各部に供給される。   The power received by the power receiving coil 6 in this way is converted from direct current to alternating current by the power conditioner 4 and supplied to each part of the building A by indoor wiring.

したがって、本実施形態の屋根構造Ａ２、建築物Ａ、瓦９においては、屋根Ａ１に配置された太陽電池モジュール２で発電した電力によって送電コイル５に電流が流れることにより、送電コイル５と受電コイル６の間で共鳴現象が生じ、送電コイル５と受電コイル６の間に発生する磁界を介して、送電コイル５から受電コイル６に太陽電池モジュール２で発電した電力を供給することができる。   Therefore, in the roof structure A2, the building A, and the tile 9 of the present embodiment, a current flows through the power transmission coil 5 by the power generated by the solar cell module 2 disposed on the roof A1, and thus the power transmission coil 5 and the power reception coil. 6, a resonance phenomenon occurs, and the electric power generated by the solar cell module 2 can be supplied from the power transmission coil 5 to the power reception coil 6 via a magnetic field generated between the power transmission coil 5 and the power reception coil 6.

すなわち、受電コイル６を建築物Ａの内部（屋内側）に設け、太陽電池モジュール２で発電した電力を磁界共鳴式の非接触給電システム３によって建築物Ａの内部の各部に供給することができ、従来の太陽光発電システムのように、屋根Ａ１や壁等に孔をあけて太陽電池モジュール２から電線を建築物Ａの内部に引き込むことを不要にできる。   That is, the power receiving coil 6 is provided inside the building A (indoor side), and the electric power generated by the solar cell module 2 can be supplied to each part inside the building A by the magnetic resonance type non-contact power feeding system 3. As in the conventional solar power generation system, it is unnecessary to make a hole in the roof A1 or a wall or the like and draw an electric wire from the solar cell module 2 into the building A.

これにより、従来のように屋根Ａ１や壁等に孔をあけて気密性、防水性、防火性、躯体の耐久性を低下させることなく、住宅等の建築物Ａの内部に太陽電池モジュール２で発電した電力を供給することが可能になる。また、電線によって外観を悪化させることを解消でき、さらに、金属管等の耐火材やコーキングの耐火剤が不要になるため、材料費、施工費の低減を図ることも可能になる。   As a result, the solar cell module 2 can be installed inside the building A such as a house without making a hole in the roof A1 or the wall as in the past and reducing the airtightness, waterproofness, fireproofing, and durability of the housing. It becomes possible to supply the generated power. In addition, it is possible to eliminate the deterioration of the external appearance due to the electric wire, and further, it becomes possible to reduce the material cost and the construction cost because a refractory material such as a metal pipe and a refractory agent for caulking are unnecessary.

また、太陽電池モジュール２を瓦９の上面側に、送電コイル５を太陽電池モジュール２に接続しつつ瓦９の下面側に一体に設けて形成した瓦９を用いることによって、屋根Ａ１に太陽電池モジュール２を支持するための架台を設ける必要がなくなる。これにより、外観の向上を図ることができ、且つこの瓦９を設置してゆくだけで容易に太陽光発電システム１を構築することが可能になる。また、屋根Ａ１に架台を固定するための孔を設ける必要がないため、この点からも、気密性、防水性、防火性、躯体の耐久性を低下させることなく、住宅等の建築物Ａの内部に太陽電池モジュール２で発電した電力を供給することが可能になる。   Further, by using the roof tile 9 formed integrally with the solar cell module 2 on the upper surface side of the roof tile 9 and integrally formed on the lower surface side of the roof tile 9 while connecting the power transmission coil 5 to the solar battery module 2, the solar cell module is used for the roof A1. There is no need to provide a frame for supporting the module 2. Thereby, the appearance can be improved, and the solar power generation system 1 can be easily constructed simply by installing the roof tile 9. In addition, since there is no need to provide a hole for fixing the pedestal on the roof A1, the airtightness, waterproofness, fireproofness, and durability of the housing can be reduced without deteriorating the durability of the housing A. It becomes possible to supply electric power generated by the solar cell module 2 inside.

さらに、太陽電池モジュール２で発電し、送電コイル５から受電コイル６に供給された直流の電力をパワーコンディショナー４で交流に変換して建築物Ａの各部に供給できる。   Furthermore, the DC power generated by the solar cell module 2 and supplied from the power transmission coil 5 to the power receiving coil 6 can be converted to AC by the power conditioner 4 and supplied to each part of the building A.

以上、本発明に係る屋根構造、建築物、瓦の一実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。   As mentioned above, although one embodiment of the roof structure concerning the present invention, a building, and a tile was described, the present invention is not limited to the above-mentioned one embodiment, and can be suitably changed in the range which does not deviate from the meaning. .

例えば、本実施形態では、瓦９が、太陽電池モジュール２を上面側に設け、送電コイル５を下面側に設けて形成されているものとしたが、図４に示すように、送電コイル５を上面側に設けて瓦９が形成されていてもよい。この場合においても、勿論、本実施形態と同様の作用効果を得ることが可能である。   For example, in the present embodiment, the roof tile 9 is formed by providing the solar cell module 2 on the upper surface side and the power transmission coil 5 on the lower surface side. However, as shown in FIG. A roof tile 9 may be formed on the upper surface side. Even in this case, it is of course possible to obtain the same effects as those of the present embodiment.

また、必ずしも瓦９に太陽電池モジュール２や送電コイル５が具備されていなくてもよく、屋根Ａ１の上に配置した太陽電池モジュール２に接続して送電コイル５が設けられていればよい。このため、従来のように架台を用いて屋根Ａ１の上に太陽電池モジュール２を設置し、この太陽電池モジュール２で発電した電力を別途設けた本実施形態と同様の磁界共鳴式の非接触給電システム３によって屋内に供給するようにしてもよい。   Moreover, the solar cell module 2 and the power transmission coil 5 do not necessarily have to be provided on the roof tile 9, and it is sufficient that the power transmission coil 5 is provided so as to be connected to the solar cell module 2 disposed on the roof A1. For this reason, the solar cell module 2 is installed on the roof A1 using a gantry as in the prior art, and the magnetic resonance type non-contact power supply similar to the present embodiment in which the electric power generated by the solar cell module 2 is separately provided. It may be supplied indoors by the system 3.

さらに、屋根Ａ１の上に設けられた送電コイル５と、屋内側に設けられた受電コイル６との間に、リピータ（レピータ、中継器）を設け、送電コイル５から受電コイル６への給電効率を維持しながら送電距離を長くするようにしてもよい。   Further, a repeater (repeater, repeater) is provided between the power transmission coil 5 provided on the roof A1 and the power reception coil 6 provided on the indoor side, and the power supply efficiency from the power transmission coil 5 to the power reception coil 6 is achieved. The transmission distance may be increased while maintaining the above.
