Description
本発明は、太陽光発電パネルおよびそれを用いた太陽光発電装置に関する。特に、省スペース性（コンパクト性）およびポータブル性が良好であるとともに、効率的に太陽光発電が可能な太陽光発電パネルおよびそれを用いた太陽光発電装置に関する。 The present invention relates to a photovoltaic power generation panel and a photovoltaic power generation device using the same. In particular, the present invention relates to a photovoltaic power generation panel capable of efficiently generating solar power while having good space saving (compactness) and portability, and a photovoltaic power generation device using the same.
太陽光発電は、従来の火力発電や原子力発電に変わるクリーンなエネルギー供給手段として、開発・研究が進められており、太陽光パネル（ソーラパネル、ソーラモジュール）は建物屋上や住宅の屋根に設置され普及しつつある。また、灯油などの燃料を必要としないことから、災害時など緊急時の発電手段としても注目されている。 Photovoltaic power generation is being developed and researched as a clean energy supply means to replace conventional thermal power generation and nuclear power generation, and solar panels (solar panels, solar modules) are installed on the roofs of buildings and houses. It is becoming popular. In addition, since it does not require fuel such as kerosene, it is attracting attention as a means of power generation in an emergency such as a disaster.
効率的な発電のために、太陽光パネルは太陽光の入射角に応じて、設置角度（パネルと接地面との角度）に傾斜されて設置されている。たとえば、特許文献１では、太陽光パネルを傾斜させて設置するための太陽光発電パネル取付架台が開示されている。 For efficient power generation, the solar panel is installed at an angle (angle between the panel and the ground plane) according to the incident angle of sunlight. For example, Patent Document 1 discloses a photovoltaic power generation panel mounting stand for installing a photovoltaic panel in an inclined manner.
しかしながら、太陽光の入射角度は、日時、季節などの時間的要因や緯度経度などの地理的要因によって異なる。そのため、たとえば、夏における最適な太陽光パネルの設置角度が、冬における最適な設置角度とは限らないし、朝、昼、夕方でも最適な設置角度が異なってくる。また、使用地域などに応じて太陽光パネルの設置角度を最適化するために、太陽光発電パネル取付架台を調整することは煩雑である。特に、災害時など緊急時においては、いち早くライフラインとして電力を確保する必要があるものの、災害救助等が優先される。そのため、設置角度の調整のために、人的資源を割くほどの余裕はないことが多い。 However, the incident angle of sunlight differs depending on temporal factors such as date and time and season, and geographical factors such as latitude and longitude. Therefore, for example, the optimum installation angle of the solar panel in summer is not always the optimum installation angle in winter, and the optimum installation angle differs even in the morning, noon, and evening. In addition, it is complicated to adjust the photovoltaic power generation panel mounting base in order to optimize the installation angle of the photovoltaic panel according to the area of use. In particular, in an emergency such as a disaster, it is necessary to secure electric power as a lifeline as soon as possible, but disaster relief is prioritized. Therefore, there is often not enough room to devote human resources to adjust the installation angle.
また、大規模な発電をするためには、当然、大規模な太陽光パネルと広大なスペースを必要とし、省スペースで効率的な発電ができる太陽光パネルが求められている。 Further, in order to generate a large-scale power generation, a large-scale solar panel and a vast space are naturally required, and a solar panel capable of saving space and efficiently generating power is required.
本発明者は、これらの問題を鋭意検討した結果、所望の設置角度に調整できる支持体と折りたたみ型の太陽光パネルとを備えることで、使用時に折りたたまれた太陽光パネルを展開し、かつ支持体の開放角度を調整し適切な設置角度に調整することで、効率的な太陽光発電を可能にすることを見出した。 As a result of diligent studies on these problems, the present inventor develops and supports a solar panel that is folded during use by providing a support that can be adjusted to a desired installation angle and a foldable solar panel. We have found that efficient solar power generation is possible by adjusting the opening angle of the body and adjusting it to an appropriate installation angle.
すなわち、本発明は、省スペース性（コンパクト性）およびポータブル性が良好であるにもかかわらず、効率的な太陽光発電が可能な太陽光発電パネルおよびそれを用いた太陽光発電装置を提供することを目的とする。 That is, the present invention provides a photovoltaic power generation panel capable of efficient photovoltaic power generation despite good space saving (compactness) and portability, and a photovoltaic power generation device using the same.

In, efficient solar power generation becomes possible.
以下、本発明にかかる太陽光パネルおよび太陽光発電装置について、適宜図面を参照しながら、詳細に説明する。 Hereinafter, the solar panel and the photovoltaic power generation device according to the present invention will be described in detail with reference to the drawings as appropriate.
本発明に係る太陽光パネルは、図１の付け番１０ａおよび１０ｂに示されるように、支持体（Ａ）１１、１１′と折りたたみ型ソーラパネル部（Ｂ）１３とを有する。また、当該折りたたみ型ソーラパネル部（Ｂ）１３が、支持体（Ａ）１１、１１′に設置されていることを特徴とする。より具体的には、支持体（Ａ）が開放された際（付番Ｃで示される開放角度が大きくなった際）に生じる山折面Ａ側に、折りたたみ型ソーラパネル部（Ｂ）１３がその基材側（非受光面側）で固定されている。 The solar panel according to the present invention has supports (A) 11, 11'and a foldable solar panel portion (B) 13 as shown in Nos. 10a and 10b of FIG. Further, the foldable solar panel portion (B) 13 is installed on the supports (A) 11 and 11'. More specifically, the foldable solar panel portion (B) 13 is on the mountain fold surface A side that occurs when the support (A) is opened (when the opening angle indicated by the number C becomes large). It is fixed on the base material side (non-light receiving surface side).
なお、支持体（Ａ）や折りたたみ型ソーラパネル部（Ｂ）の他にも、必要に応じて、適宜その他の部材を有していてもよい。 In addition to the support (A) and the foldable solar panel (B), other members may be appropriately provided as needed.
図１に示されるように、支持体（Ａ）１１、１１′は、第一の支持部１１ａ、第二の支持部１１ｂを有し、これらの支持部同士は、開閉可能に連結する支持部連結部１２，１２′によって連結している。
この支持体部は、図１の付番１１、１１′およびに示されるように、支持部連結部１２，１２′によって閉鎖した状態にも開放した状態にもすることができる。
As shown in FIG. 1, the supports (A) 11 and 11'have a first support portion 11a and a second support portion 11b, and these support portions are connected to each other so as to be openable and closable. They are connected by connecting portions 12, 12'.
The support portion can be closed or opened by the support connecting portions 12, 12'as shown in Nos. 11 and 11'and of FIG.
また、図１（Ｂ）に示されるように、支持体（Ａ）を開放した状態（すなわち、支持部連結部を起点に支持体部同士を開いた状態、換言すると、図１の付番Ｃ（開放角度）を大きくした状態）にすると、支持体（Ａ）は、山折面Ａと谷折面Ｂを形成する。そして、設置面に対して折りたたみ型ソーラパネル部（Ｂ）１３を傾けた状態で立たせることが可能となる。そのため、太陽光Ｓの入射角度に応じて、折りたたみ型ソーラパネル部（Ｂ）の表面（受光面）を適切な角度に調整することができる。 Further, as shown in FIG. 1 (B), a state in which the support (A) is open (that is, a state in which the supports are opened from each other starting from the support connecting portion, in other words, the number C in FIG. 1). When (opening angle) is increased), the support (A) forms a mountain fold surface A and a valley fold surface B. Then, the foldable solar panel portion (B) 13 can be made to stand in an inclined state with respect to the installation surface. Therefore, the surface (light receiving surface) of the foldable solar panel portion (B) can be adjusted to an appropriate angle according to the incident angle of the sunlight S.
なお、第一の支持部および第二の支持部の形状および材質は特に限定されないが、通常、扁平な直方体であり、金属製やプラスチック製である。
また、支持部連結部は、通常トルクヒンジなどヒンジ（蝶番）やネジなどが挙げられるが、支持部同士を開閉可能に連結する者である限り、特に限定されない。
The shape and material of the first support portion and the second support portion are not particularly limited, but are usually flat rectangular parallelepipeds, and are made of metal or plastic.
Further, the support portion connecting portion usually includes a hinge (hinge) such as a torque hinge, a screw, or the like, but is not particularly limited as long as the support portion can be opened and closed.
また、支持部連結部は、折りたたみ型ソーラパネル部（Ｂ）１３を任意の設置角度に傾けるために、開放角度（図１付番Ｃ）の大きさを任意に設定できるものが好ましい。このような構成を採用すると、太陽光Ｓの入射角度に応じて、折りたたみ型ソーラパネル部（Ｂ）の表面（受光面）を適切な角度に調整することができる。 Further, it is preferable that the support portion connecting portion can arbitrarily set the size of the opening angle (No. C in FIG. 1) in order to tilt the foldable solar panel portion (B) 13 to an arbitrary installation angle. When such a configuration is adopted, the surface (light receiving surface) of the foldable solar panel portion (B) can be adjusted to an appropriate angle according to the incident angle of the sunlight S.
なお、本明細書においては、折りたたみ型ソーラパネル部（Ｂ）において、ソーラパネルの受光面（すなわち、太陽光が照射されて発電を行う面）を「表面」、ソーラパネルの基材面もしくは非受光面を「裏面」と呼ぶことがある。 In the present specification, in the foldable solar panel portion (B), the light receiving surface of the solar panel (that is, the surface on which sunlight is irradiated to generate electricity) is referred to as the "surface", and the base surface or non-surface of the solar panel. The light receiving surface is sometimes referred to as the "back surface".
折りたたみ型ソーラパネル部（Ｂ）は、少なくとも２枚のソーラーパネルおよび当該ソーラパネル同士を展開自在に連結するソーラパネル連結部を有する。 The foldable solar panel portion (B) has at least two solar panels and a solar panel connecting portion that freely connects the solar panels to each other.
ソーラーパネルの数は、図２では３枚であるが、必要に応じて適宜その数を調整することができる。なお、ソーラパネルは、市販されているものが適宜使用される。たとえば、単結晶シリコン型太陽電池、多結晶シリコン型太陽電池、微結晶シリコン型太陽電池、アモルファスシリコン型太陽電池、有機薄膜太陽電池、色素増感太陽電池、ＣｄＴｅ／ＣｄＳ系太陽電池、ＣＩＳ系（カルコパイライト系）太陽電池、ＧａＡｓ系太陽電池、ＩｎＧａＡｓ太陽電池などの太陽電池とそれを固定する基材から構成されたソーラパネルが挙げられる。 The number of solar panels is three in FIG. 2, but the number can be adjusted as needed. As the solar panel, a commercially available one is appropriately used. For example, single crystal silicon type solar cells, polycrystal silicon type solar cells, microcrystal silicon type solar cells, amorphous silicon type solar cells, organic thin film solar cells, dye-sensitized solar cells, CdTe / CdS type solar cells, CIS type ( Calcopyrite-based) Solar cells such as solar cells, GaAs-based solar cells, and InGaAs solar cells, and solar panels composed of a base material for fixing the solar cells can be mentioned.
図２（Ａ）および（Ｂ）に示されるように、ソーラパネル連結部２３ｂがソーラパネル２３ａ，２３ｂ同士を展開自在に連結している。そのため、図３（Ａ）および（Ｂ）に示されるように、複数のソーラパネルが折りたたまれた（閉鎖した状態の）太陽光パネル部（Ｂ）を展開して開放した状態（つまり、ソーラパネルの受光面が太陽光に露出した状態）とすることができる。そして、この状態にすることで、ソーラパネルの表面（受光面）に太陽光を照射させて効率的な太陽光発電が可能となる。 As shown in FIGS. 2A and 2B, the solar panel connecting portion 23b connects the solar panels 23a and 23b to each other in a deployable manner. Therefore, as shown in FIGS. 3 (A) and 3 (B), a state in which a plurality of solar panels are folded (closed) and the solar panel portion (B) is expanded and opened (that is, the solar panel). The light receiving surface of the above can be exposed to sunlight). Then, in this state, the surface (light receiving surface) of the solar panel is irradiated with sunlight, and efficient solar power generation becomes possible.
また、本発明の太陽光パネルの未使用時においては、折りたたみ型ソーラパネル部（Ｂ）において、ソーラパネルが折りたたまれた状態（閉じた状態）とすることができるため、省スペース性（コンパクト性）およびポータブル性が良好である。 Further, when the solar panel of the present invention is not used, the solar panel can be in a folded state (closed state) in the foldable solar panel portion (B), which saves space (compactness). ) And good portability.
ソータパネル連結部としては、ソーラパネル２３ａ、２３ｂ同士を展開自在に連結するものであれば、特に限定されないが、たとえばトルクヒンジなどが挙げられる。 The sorter panel connecting portion is not particularly limited as long as the solar panels 23a and 23b are freely connected to each other, and examples thereof include a torque hinge.
また、本発明の太陽光パネルは、通常、太陽光発電装置に使用される。すなわち、本発明に係る太陽光発電装置は、上述の太陽光パネルと、当該太陽光パネルと電気的に接続された蓄電池とを有し、必要に応じてその他の部材を備えていてもよい。また、これらの部材は、支持体内部に設置されていてもよいし、支持体外部に設置されていてもよい。ポータブル性などを重視するのであれば、これらの部材は、支持体内部に設置されていていることが好ましい。 In addition, the solar panel of the present invention is usually used in a photovoltaic power generation device. That is, the photovoltaic power generation device according to the present invention has the above-mentioned solar panel and a storage battery electrically connected to the solar panel, and may be provided with other members as necessary. Further, these members may be installed inside the support or may be installed outside the support. If portability is important, these members are preferably installed inside the support.
蓄電池としては、太陽光パネルの受光面で太陽光を受光して得られた電気を充電し、必要に応じて放電できるものであれば特に限定されない。たとえば、鉛蓄電池、ニッケル水素電池、ＮＡＳ電池（ナトリウム硫黄電池）、リチウムイオン電池、ニッケルカドミウム電池などが挙げられる。なお、太陽光パネルと蓄電池とが直接電気的に接続されていてもよい。 The storage battery is not particularly limited as long as it can charge the electricity obtained by receiving sunlight on the light receiving surface of the solar panel and discharge it as needed. For example, lead-acid batteries, nickel-metal hydride batteries, NAS batteries (sodium-sulfur batteries), lithium-ion batteries, nickel-cadmium batteries and the like can be mentioned. The solar panel and the storage battery may be directly electrically connected.
インバータ（ＡＣ−ＤＣインバータ）には、太陽光パネルから得られた直流電気又は蓄電池から放電された直流電気を交流電気に変換するために好適に設置される。インバーターとしては、電圧形インバータや電流形インバータであってもよい。
チャージコントローラ（ソーラーチャージコントローラ）は、当該太陽光パネルから得られた直流電気が蓄電池に過充電されることやソーラパネルへの電流の逆流を防ぐために設置されていることが好ましい。本発明の太陽光発電装置から得られた電気を使用する機器の消費電力と使用時間や蓄電池のバッテリー容量などに応じて適宜選択される。
バッテリーマネジメントシステム（ＢＭＳ）は、蓄電池（リチウムバッテリーなど）の総電圧、電池残量推定、および過放電及び過充電などの異常検知をするために好適に設置される。
更には、停電時等に暗闇を照らすために、ＬＥＤライトが設置されていることが好ましい。
その他、必要に応じて、ＵＳＢソケットやＡＣアダプターを備えていても良い。
The inverter (AC-DC inverter) is suitably installed for converting DC electricity obtained from a solar panel or DC electricity discharged from a storage battery into AC electricity. The inverter may be a voltage type inverter or a current type inverter.
The charge controller (solar charge controller) is preferably installed in order to prevent the direct current electricity obtained from the solar panel from being overcharged in the storage battery and the backflow of current to the solar panel. It is appropriately selected according to the power consumption and usage time of the device using electricity obtained from the photovoltaic power generation device of the present invention, the battery capacity of the storage battery, and the like.
The battery management system (BMS) is suitably installed for detecting the total voltage of a storage battery (such as a lithium battery), estimating the remaining battery level, and detecting abnormalities such as over-discharging and over-charging.
Furthermore, it is preferable that an LED light is installed in order to illuminate the darkness in the event of a power failure or the like.
In addition, if necessary, a USB socket or an AC adapter may be provided.
また、「電気的に接続された」とは、銅線など有線によって電気的に接続されているものや、ワイヤレス給電システムなど無線によって電気的に接続されているものも含む。
通常、太陽光パネル、ソーラーチャージャーコントローラ、バッテリーマネージメントシステム、蓄電池、ＤＣ−ＡＣインバータが順次電気的に接続されている。また、別途、ソーラーチャージャーコントローラに照明用ＬＥＤライトやＵＳＢソケットが電気的に接続されていることが好ましい。また、ＡＣアダプターがバッテリーマネージメントシステムに電気的に接続されていてもよい。
なお、蓄電池がリチウムイオン電池ではない場合（例：鉛蓄電池、ニッケル水素電池、ニッケルカドミウム電池など）、バッテリーマネージメントシステムを設けなくても良い。
また、ＤＣ−ＡＣインバータは電流値が一般的に大きいことを考慮すると、ソーラーチャージャーコントローラを介さずに、直接蓄電池に電気的に接続することが好ましい。
In addition, "electrically connected" includes those that are electrically connected by wire such as copper wire and those that are electrically connected by wireless such as a wireless power supply system.
Normally, a solar panel, a solar charger controller, a battery management system, a storage battery, and a DC-AC inverter are electrically connected in sequence. Further, it is preferable that the LED light for lighting and the USB socket are electrically connected to the solar charger controller separately. Further, the AC adapter may be electrically connected to the battery management system.
If the storage battery is not a lithium-ion battery (eg, lead-acid battery, nickel-metal hydride battery, nickel-cadmium battery, etc.), it is not necessary to provide a battery management system.
Further, considering that the DC-AC inverter generally has a large current value, it is preferable to electrically connect the DC-AC inverter directly to the storage battery without using the solar charger controller.
また、図１の付番１４に示されるように、本発明に係る太陽光パネルまたは太陽光発電装置には、その山折面側（折りたたみ型ソーラパネル部（Ｂ）の設置側）において、間接照明用発光手段を有することが好ましい。このように構成することで、部屋など場所の大きさや空間の形状によらず、間接照明用発光手段の照射角度や照射方向を調整して、間接照明を最適化することができるためである。 Further, as shown in No. 14 of FIG. 1, the solar panel or the photovoltaic power generation device according to the present invention is provided with indirect lighting on the mountain fold surface side (installation side of the foldable solar panel portion (B)). It is preferable to have a light emitting means for light emission. This is because the indirect lighting can be optimized by adjusting the irradiation angle and the irradiation direction of the light emitting means for indirect lighting regardless of the size of the place such as a room or the shape of the space.
間接照明用発光手段は、固定型であってもよいが、、間接照明用発光手段の照射角度や照射方向の調整を容易にするために、照射角度や照射方向を可変自在に構成されていることが好ましい。
なお、間接照明用発光手段としては、特に限定されないが、ＬＥＤライト、白熱電球、ハロゲンライトなどが挙げられるが、特に、非常用電源として使用するためには、消費電力が小さいという観点からＬＥＤライトが望ましい。
The light emitting means for indirect lighting may be a fixed type, but the irradiation angle and the irradiation direction are variably configured in order to facilitate the adjustment of the irradiation angle and the irradiation direction of the light emitting means for indirect lighting. Is preferable.
The light emitting means for indirect lighting is not particularly limited, and examples thereof include an LED light, an incandescent light bulb, a halogen light, and the like. In particular, the LED light is used from the viewpoint of low power consumption when used as an emergency power source. Is desirable.
本発明に係る太陽光パネル又は太陽光発電装置において、山折面側に、部材間の隙間部分にシーリングするなど防水構造や耐雨構造を採用することができる。このような構成にすることで、にわか雨など突然の降雨の際であっても、太陽光パネル又は太陽光発電装置の内部への浸水による故障を防ぐことができる。 In the solar panel or the photovoltaic power generation device according to the present invention, a waterproof structure or a rainproof structure can be adopted, such as sealing the gap between the members on the mountain fold surface side. With such a configuration, even in the case of sudden rainfall such as a shower, it is possible to prevent a failure due to water intrusion into the solar panel or the photovoltaic power generation device.
ただし、防水構造や耐雨性構造を採用すると、太陽光発電装置の内部（特に、支持体（Ａ）内部）の気密性が高まるため、内部の熱気を排出しにくいものとなってしまう。特に、発電量が大きかったり、電子部品の数や密集度が大きかったりすると、一層その傾向が顕著になる。
そこで、本発明に係る太陽光パネル又は太陽光発電装置には、その谷折面側（折りたたみ型ソーラパネル部（Ｂ）の非設置側）において、排熱口（図１の付番１５）と、当該排熱口の近傍かつ支持体内部に排熱手段（図示せず）を有することが好ましい。このように構成することで、山折面側に防水構造や耐雨性構造を施した結果、支持体内部の気密性が高い状態であったとしても、図１の付番Ｈに示されるように、熱を太陽光発電装置の内部から外部へと効率的に排出することができ、防水性や耐雨性と排熱性とを両立することができる。
However, if a waterproof structure or a rainproof structure is adopted, the airtightness of the inside of the photovoltaic power generation device (particularly, the inside of the support (A)) is increased, so that it becomes difficult to discharge the hot air inside. In particular, when the amount of power generation is large, or when the number and density of electronic components are large, this tendency becomes even more pronounced.
Therefore, the solar panel or the photovoltaic power generation device according to the present invention has a heat exhaust port (number 15 in FIG. 1) on the valley folding surface side (non-installed side of the foldable solar panel portion (B)). , It is preferable to have a heat exhaust means (not shown) in the vicinity of the heat exhaust port and inside the support. With this configuration, even if the inside of the support is highly airtight as a result of providing a waterproof structure and a rain-resistant structure on the mountain fold surface side, as shown in No. H of FIG. Heat can be efficiently discharged from the inside to the outside of the photovoltaic power generation device, and both waterproofness, rain resistance and heat exhaustability can be achieved.
排熱口の形状や大きさは、適宜選択され、当該排熱口の近傍かつ支持体内部に設けられる排熱手段としては、たとえば、排熱ファンが装着されたモーターなどがある。 The shape and size of the heat exhaust port are appropriately selected, and examples of the heat exhaust means provided in the vicinity of the heat exhaust port and inside the support include a motor equipped with a heat exhaust fan.
本発明に係る太陽光発電装置は、未使用時（収容時）には省スペース性とポータブル性に優れるとともに、使用時（発電時・充電時）には効率的な太陽光発電が可能である。そのため、災害時など緊急時に好適に使用され、設置場所を問わず、室内外での発電装置としても好適に使用される。 The photovoltaic power generation device according to the present invention is excellent in space saving and portability when not in use (when housed), and can efficiently generate photovoltaic power when in use (during power generation / charging). .. Therefore, it is suitably used in an emergency such as a disaster, and is also suitably used as an indoor / outdoor power generation device regardless of the installation location.
