Description

本発明の実施形態は、屋外に設置される屋外制御盤に関する。   Embodiments described herein relate generally to an outdoor control panel installed outdoors.

屋外制御盤は、密閉構造の筐体内に、例えば計測器、監視装置、通信装置などの各種の電気機器を収容している。屋外制御盤は、屋外に設置されるため、太陽光や、屋外大気の温度変化などに直接的に晒される。そのため、筐体内の温度が上昇し過ぎて、内部の電気機器に悪影響を及ぼすおそれがある。そこで、例えば特許文献１に開示されている屋外制御盤は、筐体の屋根および外周をプラスチック遮光板で覆うことにより、太陽光の直射を遮って筐体内の温度上昇を抑えるようにしている。   The outdoor control panel accommodates various electric devices such as a measuring instrument, a monitoring device, and a communication device in a sealed housing. Since the outdoor control panel is installed outdoors, it is directly exposed to sunlight and temperature changes in the outdoor air. For this reason, the temperature in the housing rises excessively, which may adversely affect the internal electrical equipment. Therefore, for example, the outdoor control panel disclosed in Patent Document 1 covers the roof and outer periphery of the casing with a plastic light shielding plate to block direct sunlight and suppress the temperature rise in the casing.

特開平４−２１７８０３号公報JP-A-4-217803

ところで、屋外制御盤において筐体内の温度を上昇させる一要因となる太陽光は、一方では、環境や生態系に優しいクリーンなエネルギーとして注目されている。上述した通り、屋外制御盤が設置される屋外という環境は、太陽光に直接的に晒される過酷な環境であるが、見方を変えれば、クリーンなエネルギーである太陽光を有効利用しやすい環境でもある。   By the way, sunlight, which is one factor that raises the temperature in the casing of the outdoor control panel, has been attracting attention as clean energy friendly to the environment and ecosystem. As mentioned above, the outdoor environment where the outdoor control panel is installed is a harsh environment that is directly exposed to sunlight, but if you change your view, even in an environment where you can effectively use sunlight, which is clean energy is there.

そこで、本実施形態では、屋外に設置される屋外制御盤に関し、筐体内の温度上昇を抑えることができ、且つ、太陽光を有効利用することができるようにした構成を提供する。   Therefore, in the present embodiment, a configuration is provided that can suppress an increase in temperature in the housing and can effectively use sunlight with respect to an outdoor control panel installed outdoors.

本実施形態に係る屋外制御盤は、筐体、上部太陽光発電パネル、側部太陽光発電パネルを備える。筐体は、直方体形であり、内部に電気機器を収容する。上部太陽光発電パネルは、屋外制御盤が屋外に設置された状態において、前記筐体の上面を覆う。側部太陽光発電パネルは、屋外制御盤が屋外に設置された状態において、前記筐体の側面を覆う。   The outdoor control panel according to the present embodiment includes a housing, an upper solar power generation panel, and a side solar power generation panel. The casing has a rectangular parallelepiped shape, and houses an electrical device inside. The upper solar power generation panel covers the upper surface of the casing in a state where the outdoor control panel is installed outdoors. The side solar power generation panel covers the side surface of the casing in a state where the outdoor control panel is installed outdoors.

以下、屋外制御盤に係る複数の実施形態について図面を参照しながら説明する。なお、各実施形態において、実質的に同一の要素には同一の符号を付して説明を省略する。また、各実施形態は、例えば日本国内などの北半球で屋外制御盤を使用する場合を想定しているものとする。   Hereinafter, a plurality of embodiments according to an outdoor control panel will be described with reference to the drawings. In each embodiment, substantially the same elements are denoted by the same reference numerals, and the description thereof is omitted. Moreover, each embodiment assumes the case where an outdoor control panel is used in the northern hemisphere, for example, in Japan.

（第１実施形態）
図１および図２に例示する屋外制御盤１０は、ほぼ直方体形の筐体１１の内部に電気機器１２を収容している。屋外制御盤１０は、屋外に設けられた基礎面上に架台を介して据え付けられる。筐体１１は、屋外に設置された状態で側面となる４つの面のうちの一面が開口した矩形箱状をなす。筐体１１の開口には扉１３が開閉可能に設けられている。扉１３の裏面には、図示しないパッキンが設けられている。パッキンは、扉１３が筐体１１の開口を閉じた閉状態において、扉１３の周囲から雨水等が筐体１１内に浸入することを防止する。 (First embodiment)
An outdoor control panel 10 illustrated in FIGS. 1 and 2 accommodates an electric device 12 in a substantially rectangular parallelepiped casing 11. The outdoor control panel 10 is installed on a foundation surface provided outdoors via a gantry. The casing 11 has a rectangular box shape in which one of four surfaces serving as side surfaces is opened in an outdoor state. A door 13 is provided at the opening of the housing 11 so as to be openable and closable. A packing (not shown) is provided on the back surface of the door 13. The packing prevents rainwater or the like from entering the casing 11 from the periphery of the door 13 in the closed state where the door 13 closes the opening of the casing 11.

扉１３が筐体１１の開口を閉じた閉状態では、筐体１１の内部は、空気の流入および流出がほぼ遮断された、基本的には密閉された状態となる。即ち、扉１３の下部には、通風部１３ａが設けられている。そのため、扉１３が筐体１１の開口を閉じた閉状態において、筐体１１の内部は、完全な密閉状態とはならず、ある程度の空気の流入および流出が可能なほぼ密閉された状態となる。   In the closed state in which the door 13 closes the opening of the housing 11, the inside of the housing 11 is basically in a sealed state in which inflow and outflow of air are substantially blocked. That is, a ventilation portion 13 a is provided at the lower portion of the door 13. Therefore, in the closed state where the door 13 closes the opening of the housing 11, the interior of the housing 11 is not completely sealed, but is almost sealed so that a certain amount of air can flow in and out. .

通風部１３ａは、いわゆるガラリ構造となっている。また、通風部１３ａは、扉１３の裏側において下側ではなく上側に向かって開放するガラリ構造となっている。このようなガラリ構造によれば、扉１３の表面側からの雨水が筐体１１内に入り込みにくくなる。なお、通風部１３ａは、扉１３の表側において下側に向かって開放するガラリ構造としてもよい。このようなガラリ構造によっても、扉１３の表面側からの雨水が筐体１１内に入り込みにくくなる。また、通風部１３ａは、空気中の塵埃を捕獲するフィルタを備える構成としてもよい。   The ventilation portion 13a has a so-called louver structure. Moreover, the ventilation part 13a has a louver structure that opens toward the upper side rather than the lower side on the back side of the door 13. According to such a louver structure, rainwater from the front surface side of the door 13 does not easily enter the housing 11. In addition, the ventilation part 13a is good also as the louver structure opened toward the lower side in the front side of the door 13. As shown in FIG. Such a louver structure also makes it difficult for rainwater from the surface side of the door 13 to enter the housing 11. Moreover, the ventilation part 13a is good also as a structure provided with the filter which captures the dust in air.

筐体１１の上面には、傾斜枠１４が取り付けられている。傾斜枠１４の前面は、その上辺が水平な矩形板状となっている。傾斜枠１４の両側面は、その上辺が、扉１３が設けられている前面側から後面側に向けて下降するように傾斜している。即ち、傾斜枠１４は、扉１３側である前面側ほど高い枠状の構成となっている。このように構成される傾斜枠１４は、筐体１１の上部に降り注いだ雨水が扉１３側に流れ落ちることを回避する。また、傾斜枠１４は、筐体１１上部の空間に、鳥や動物などが侵入することを回避する。なお、屋外制御盤１０は、傾斜枠１４を備えない構成としてもよい。   An inclined frame 14 is attached to the upper surface of the housing 11. The front surface of the inclined frame 14 has a rectangular plate shape whose upper side is horizontal. Both side surfaces of the inclined frame 14 are inclined such that the upper sides thereof descend from the front side where the door 13 is provided toward the rear side. That is, the inclined frame 14 has a frame-like configuration that is higher toward the front side that is the door 13 side. The inclined frame 14 configured in this way avoids rainwater that has poured onto the top of the housing 11 from flowing down to the door 13 side. Further, the inclined frame 14 prevents a bird or an animal from entering the space above the housing 11. The outdoor control panel 10 may be configured without the inclined frame 14.

電気機器１２は、各種の計測器、監視装置、通信装置などである。筐体１１内の奥面、つまり、扉１３に対向する面には、上下方向に延びる配置板１５が設けられている。電気機器１２は、筐体１１の内部において、この配置板１５の前面に取り付けられている。この構成によれば、例えば管理者が扉１３を開けると、正面に電気機器１２が配置された状態となる。そのため、管理者は、電気機器１２を見やすく、作業性を向上することができる。また、後述する指向状態により屋外制御盤１０が屋外に設置されている場合において扉１３を開けた状態では、電気機器１２は北側を向いているため、南側からの太陽光が直接的に電気機器１２にあたるおそれが無く、従って、管理者は、電気機器１２を見やすく、作業性を向上することができる。また、電気機器１２に南側からの太陽光が直接的にあたるおそれが無いため、太陽光による電気機器１２の劣化を抑えることができる。   The electric device 12 is various measuring instruments, monitoring devices, communication devices, and the like. An arrangement plate 15 extending in the vertical direction is provided on the inner surface of the housing 11, that is, the surface facing the door 13. The electric device 12 is attached to the front surface of the arrangement plate 15 inside the housing 11. According to this configuration, for example, when the administrator opens the door 13, the electric device 12 is placed on the front. Therefore, the administrator can easily see the electrical device 12 and improve workability. In addition, when the outdoor control panel 10 is installed outdoors in the orientation state described later, when the door 13 is opened, the electric device 12 faces the north side, so that sunlight from the south side is directly connected to the electric device. Therefore, the administrator can easily see the electric device 12 and improve workability. Moreover, since there is no possibility that the sunlight from the south side may directly hit the electric device 12, it is possible to suppress the deterioration of the electric device 12 due to the sunlight.

また、筐体１１の内部には、ヒータ１６が設けられている。例えば、屋外制御盤１０が太陽光に晒されない夜間においては、筐体１１内の温度が低下して結露が発生するおそれがあり、このような結露が電気機器１２に悪影響を及ぼすおそれがある。ヒータ１６は、例えば筐体１１内の温度が所定温度以下に低下する場合に駆動され、これにより、結露の発生を防止する。この場合、ヒータ１６は、筐体１１内の下部に設けられている。そのため、筐体１１内において温度が低下しやすい下部の空気を効率良く温めることができ、また、ヒータ１６により温められた空気が筐体１１内を上昇することから、筐体１１内全体の空気を効率良く温めることができる。   A heater 16 is provided inside the housing 11. For example, at night when the outdoor control panel 10 is not exposed to sunlight, the temperature in the housing 11 may decrease and condensation may occur, and such condensation may adversely affect the electrical device 12. The heater 16 is driven, for example, when the temperature in the housing 11 falls below a predetermined temperature, thereby preventing the occurrence of condensation. In this case, the heater 16 is provided in the lower part in the housing 11. Therefore, the lower air whose temperature is likely to decrease in the housing 11 can be efficiently heated, and the air heated by the heater 16 rises in the housing 11, so that the air in the entire housing 11 Can be efficiently heated.

また、筐体１１の内部には、送風ファン１７が設けられている。この送風ファン１７は、筐体１１内の空気を外部に排出する。送風ファン１７による送風作用により、筐体１１内の空気が外部に排出され、一方、通風部１３ａから外部の空気が筐体１１内に流入する。これにより、筐体１１内の空気を入れ換えることができ、筐体１１内の空気に含まれる塵埃が電気機器１２に悪影響を及ぼすこと、また、筐体１１内の空気に含まれる水分が結露して電気部品１２に悪影響を及ぼすことを回避することができる。   A blower fan 17 is provided inside the housing 11. The blower fan 17 discharges the air in the housing 11 to the outside. By the air blowing action by the blower fan 17, the air in the housing 11 is discharged to the outside, and the outside air flows into the housing 11 from the ventilation portion 13 a. As a result, the air in the housing 11 can be replaced, dust contained in the air in the housing 11 has an adverse effect on the electric device 12, and moisture contained in the air in the housing 11 is condensed. Thus, adverse effects on the electrical component 12 can be avoided.

屋外制御盤１０は、筐体１１の外面に、矩形で薄板状の複数の太陽光発電パネル２０を備えている。この場合、屋外制御盤１０は、太陽光発電パネル２０として、１つの上部太陽光発電パネル２０ｕと、４つの側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎを備えている。上部太陽光発電パネル２０ｕは、屋外制御盤１０が屋外に設置された状態において、筐体１１の上面、より具体的には傾斜枠１４の上部を覆う。ここで、傾斜枠１４の上部が屋外制御盤１０の前面側から後面側に向けて下降するように傾斜していることから、上部太陽光発電パネル２０ｕも屋外制御盤１０の前面側から後面側に向けて下降するように傾斜した状態で取り付けられている。また、上部太陽光発電パネル２０ｕは、支持金具２１を介して筐体１１の上部に取り付けられており、筐体１１の上部、さらには傾斜枠１４の上部から離間した状態となっている。また、上部太陽光発電パネル２０ｕの裏面側には白色系の塗装が施されている。これにより、上部太陽光発電パネル２０ｕを透過する太陽光は、白色系の塗装により反射され、筐体１１の上面まで届きにくくなっている。   The outdoor control panel 10 includes a plurality of rectangular and thin photovoltaic panels 20 on the outer surface of the housing 11. In this case, the outdoor control panel 10 includes, as the solar power generation panel 20, one upper solar power generation panel 20u and four side solar power generation panels 20e, 20w, 20s, and 20n. The upper solar power generation panel 20u covers the upper surface of the housing 11, more specifically, the upper portion of the inclined frame 14 in a state where the outdoor control panel 10 is installed outdoors. Here, since the upper part of the inclined frame 14 is inclined so as to descend from the front side of the outdoor control panel 10 toward the rear side, the upper solar power generation panel 20 u is also rear side from the front side of the outdoor control panel 10. It is attached in an inclined state so as to descend toward the front. Further, the upper solar power generation panel 20 u is attached to the upper portion of the housing 11 via the support fitting 21 and is separated from the upper portion of the housing 11 and further from the upper portion of the inclined frame 14. In addition, white paint is applied to the back surface side of the upper photovoltaic power generation panel 20u. Thereby, the sunlight which permeate | transmits the upper photovoltaic panel 20u is reflected by the white type | system | group coating, and it is difficult to reach the upper surface of the housing | casing 11. FIG.

側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎは、屋外制御盤１０が屋外に設置された状態において、筐体１１の４つの側面をそれぞれ覆う。ここで、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎは、何れも筐体１１の側面に沿って上下方向に延びた状態、つまり、垂直な状態で取り付けられている。また、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎは、それぞれ支持金具２１を介して筐体１１の側面に取り付けられており、筐体１１の側面から離間した状態となっている。また、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側には白色系の塗装が施されている。これにより、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎを透過する太陽光は、白色系の塗装により反射され、筐体１１の側面まで届きにくくなっている。   The side solar power generation panels 20e, 20w, 20s, and 20n cover the four side surfaces of the housing 11 in a state where the outdoor control panel 10 is installed outdoors. Here, all of the side solar power generation panels 20e, 20w, 20s, and 20n are attached in a state of extending vertically along the side surface of the casing 11, that is, in a vertical state. Further, the side photovoltaic power generation panels 20 e, 20 w, 20 s, and 20 n are attached to the side surface of the housing 11 via the support fittings 21, respectively, and are separated from the side surface of the housing 11. Moreover, the white side coating is given to the back surface side of the side photovoltaic power generation panels 20e, 20w, 20s, and 20n. Thereby, the sunlight which permeate | transmits the side part photovoltaic power generation panels 20e, 20w, 20s, and 20n is reflected by white type | system | group coating, and it is difficult to reach the side surface of the housing | casing 11. FIG.

屋外制御盤１０は、扉１３を開いたときの南方向からの太陽光の直射による電気部品１２への悪影響を防ぐために、また、電気備品１２の表示等を見やすくするために、筐体１１の４つの側面のうち扉１３が設けられている側面を北方に向けた状態で設置される。その結果、屋外制御盤１０は、例えば筐体１１の４つの側面をそれぞれ東方、西方、南方、北方に向けた状態で屋外に設置されることになる。そして、このような指向状態で屋外に設置される屋外制御盤１０によれば、図２に例示するように、側部太陽光発電パネル２０ｅは、筐体１１の東側の側面を覆う。側部太陽光発電パネル２０ｗは、筐体１１の西側の側面を覆う。側部太陽光発電パネル２０ｓは、筐体１１の後側となる南側の側面を覆う。側部太陽光発電パネル２０ｎは、筐体１１の前側となる北側の側面を覆う。   The outdoor control panel 10 prevents the adverse effect on the electrical component 12 due to direct sunlight from the south when the door 13 is opened, and makes the display of the electrical equipment 12 easier to see. The four side surfaces are installed with the side surface on which the door 13 is provided facing north. As a result, the outdoor control panel 10 is installed outdoors, for example, with the four side surfaces of the housing 11 facing east, west, south, and north, respectively. And according to the outdoor control panel 10 installed outdoors in such a directional state, the side photovoltaic power generation panel 20 e covers the east side surface of the housing 11 as illustrated in FIG. 2. The side photovoltaic power generation panel 20 w covers the west side surface of the housing 11. The side photovoltaic power generation panel 20 s covers the south side surface that is the rear side of the housing 11. The side solar power generation panel 20 n covers the north side surface which is the front side of the housing 11.

また、図２に例示するように、屋外に設置された状態において屋外制御盤１０を上方から見ると、上部太陽光発電パネル２０ｕは、筐体１１の上面全体および当該筐体１１の側面を覆う４つの側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの上面全体を覆う。即ち、上部太陽光発電パネル２０ｕの面積は、４つの側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎにより囲まれる仮想的な矩形の面積よりも大きい。また、上部太陽光発電パネル２０ｕは、筐体１１の上面、より具体的には傾斜枠１４の上部からの離間寸法が全体的に均一となっている。上部太陽光発電パネル２０ｕの筐体１１の上面からの離間寸法は、例えば４ｃｍ程である。   In addition, as illustrated in FIG. 2, when the outdoor control panel 10 is viewed from above while being installed outdoors, the upper solar power generation panel 20 u covers the entire top surface of the housing 11 and the side surface of the housing 11. Covers the entire top surface of the four side photovoltaic panels 20e, 20w, 20s, 20n. That is, the area of the upper photovoltaic panel 20u is larger than the area of a virtual rectangle surrounded by the four side photovoltaic panels 20e, 20w, 20s, and 20n. Further, the upper solar power generation panel 20u has a uniform separation dimension from the upper surface of the housing 11, more specifically, from the upper part of the inclined frame 14. The distance from the upper surface of the housing 11 of the upper photovoltaic panel 20u is, for example, about 4 cm.

また、屋外に設置された状態において屋外制御盤１０を前側つまり扉１３側である北側から見ると、側部太陽光発電パネル２０ｎは、側部太陽光発電パネル２０ｅおよび側部太陽光発電パネル２０ｗの北側の端面を覆っていない。よって、扉１３を開く場合に、側部太陽光発電パネル２０ｎの東側の端面が側部太陽光発電パネル２０ｅの北側の端面に干渉すること、あるいは、側部太陽光発電パネル２０ｎの西側の端面が側部太陽光発電パネル２０ｗの北側の端面に干渉することを回避することができ、扉１３を大きく開くことができる。   In addition, when the outdoor control panel 10 is viewed from the front side, that is, the north side that is the door 13 side in a state where it is installed outdoors, the side solar power generation panel 20n and the side solar power generation panel 20e and the side solar power generation panel 20w Does not cover the end face of the north side. Therefore, when the door 13 is opened, the end face on the east side of the side photovoltaic power generation panel 20n interferes with the end face on the north side of the side photovoltaic power generation panel 20e, or the end face on the west side of the side photovoltaic power generation panel 20n. Can be prevented from interfering with the end face on the north side of the side photovoltaic power generation panel 20w, and the door 13 can be greatly opened.

一方、屋外に設置された状態において屋外制御盤１０を後側つまり扉１３とは反対側である南側から見ると、側部太陽光発電パネル２０ｓは、側部太陽光発電パネル２０ｅおよび側部太陽光発電パネル２０ｗの南側の端面を覆っている。よって、南側からの太陽光が側部太陽光発電パネル２０ｅ，２０ｗの南側の端部に直接的にあたることを回避することができ、例えば受光基板等の端子出し等が集中される構造的に弱い側部太陽光発電パネル２０ｅ，２０ｗの端部を太陽光から保護することができる。また、南側からの太陽光が側部太陽光発電パネル２０ｅ，２０ｗの裏面と筐体１１の側面との間に直接的に入射することを回避することができ、側部太陽光発電パネル２０ｅ，２０ｗの裏面側ひいては筐体１１内の温度上昇を抑えることができる。また、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎは、筐体１１の側面からの離間寸法が全体的に均一となっている。側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの筐体１１の側面からの離間寸法は、例えば４ｃｍ程である。   On the other hand, when the outdoor control panel 10 is viewed from the rear side, that is, the south side opposite to the door 13 in the state where it is installed outdoors, the side solar power generation panel 20s includes the side solar power generation panel 20e and the side solar power generation panel. It covers the end face on the south side of the photovoltaic panel 20w. Therefore, it is possible to avoid that sunlight from the south side directly hits the south side end portions of the side photovoltaic power generation panels 20e and 20w. The edge part of the side part photovoltaic power generation panel 20e, 20w can be protected from sunlight. Moreover, it can avoid that the sunlight from the south side injects directly between the back surface of the side photovoltaic power generation panel 20e, 20w, and the side surface of the housing | casing 11, and the side photovoltaic power generation panel 20e, The temperature rise in the housing 11 can be suppressed as a result of the rear side of 20w. Further, the side solar power generation panels 20e, 20w, 20s, and 20n have a uniform separation dimension from the side surface of the housing 11. The separation distance from the side surface of the housing 11 of the side solar power generation panels 20e, 20w, 20s, and 20n is, for example, about 4 cm.

屋外制御盤１０によれば、屋外に設置された状態において、筐体１１の上面は上部太陽光発電パネル２０ｕにより覆われ、筐体１１の４つの側面はそれぞれ側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎにより覆われている。この構成によれば、上部太陽光発電パネル２０ｕおよび側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎにより筐体１１に対する太陽光の直射を遮ることができ、筐体１１内の温度上昇を抑えることができる。また、上部太陽光発電パネル２０ｕおよび側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎに太陽光が入射することで発電を行うことができ、クリーンなエネルギーである太陽光を有効利用することができる。   According to the outdoor control panel 10, when installed outdoors, the upper surface of the housing 11 is covered with the upper solar power generation panel 20u, and the four side surfaces of the housing 11 are side solar power generation panels 20e and 20w, respectively. , 20s, 20n. According to this configuration, the upper solar power generation panel 20u and the side solar power generation panels 20e, 20w, 20s, and 20n can block direct sunlight from being incident on the casing 11, and suppress an increase in temperature in the casing 11. be able to. Further, it is possible to generate power when sunlight is incident on the upper solar power generation panel 20u and the side solar power generation panels 20e, 20w, 20s, and 20n, and to effectively use sunlight that is clean energy. it can.

また、屋外制御盤１０によれば、屋外に設置された状態において上方から見て、上部太陽光発電パネル２０ｕは、筐体１１の全体および４つの側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの全体を覆っている。この構成によれば、太陽光が側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの上側の端部に直接的にあたることを回避することができ、構造的に弱い側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの端部を太陽光から保護することができる。また、太陽光が側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面と筐体１１の側面との間に直接的に入射することを回避することができ、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側ひいては筐体１１内の温度上昇を抑えることができる。   Further, according to the outdoor control panel 10, when viewed from above in the state of being installed outdoors, the upper solar power generation panel 20u includes the entire housing 11 and the four side solar power generation panels 20e, 20w, 20s, It covers the entire 20n. According to this structure, it can avoid that sunlight hits directly the upper edge part of the side photovoltaic power generation panel 20e, 20w, 20s, 20n, and the side photovoltaic power generation panel 20e which is structurally weak. , 20w, 20s, 20n can be protected from sunlight. Moreover, it can avoid that sunlight injects directly between the back surface of the side photovoltaic power generation panel 20e, 20w, 20s, and 20n, and the side surface of the housing | casing 11, and the side photovoltaic power generation panel 20e. , 20w, 20s, 20n, and thus the temperature rise in the housing 11 can be suppressed.

また、屋外制御盤１０によれば、上部太陽光発電パネル２０ｕは筐体１１の上面から離間しており、また、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎは、それぞれ筐体１１の側面から離間している。この構成によれば、上部太陽光発電パネル２０ｕの裏面と筐体１１の上面との間における空気の流れ、および、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面と筐体１１の側面との間における空気の流れを確保することができ、即ち、筐体１１の周囲において空気が流れる状態を実現することができる。よって、太陽光が直射せず冷たい状態の空気により筐体１１を効率良く冷却することができる。   Further, according to the outdoor control panel 10, the upper solar power generation panel 20u is separated from the upper surface of the casing 11, and the side solar power generation panels 20e, 20w, 20s, and 20n are respectively provided on the casing 11. Separated from the side. According to this configuration, the air flow between the back surface of the upper solar power generation panel 20u and the upper surface of the housing 11, and the back surface of the side solar power generation panels 20e, 20w, 20s, 20n and the housing 11 A flow of air between the side surfaces can be secured, that is, a state in which air flows around the casing 11 can be realized. Therefore, the housing | casing 11 can be efficiently cooled with the air of the cold state which sunlight does not shine directly.

また、屋外制御盤１０によれば、近年、薄型化や軽量化が進められている太陽光発電パネルをいわゆる遮光板として機能させる構成であるので、筐体１１内の温度上昇を抑え、且つ、クリーンなエネルギーである太陽光を有効利用するという効果を奏しつつ、屋外制御盤１０全体のコンパクト化や軽量化を図ることができる。   Moreover, according to the outdoor control panel 10, since it is a structure which functions as a so-called light-shielding plate, a photovoltaic power generation panel that has been reduced in thickness and weight in recent years, the temperature rise in the housing 11 is suppressed, and The outdoor control panel 10 as a whole can be made compact and light while achieving the effect of effectively using sunlight, which is clean energy.

また、近年の太陽光発電パネルは、例えば発光素子を備えたものが考えられている。よって、このような発光機能を備えた太陽光発電パネルを筐体１１の上面および側面に取り付けることで、あるいは、混在させることで、太陽光発電パネルの色を変化させたり、太陽光発電パネル上に模様や文字などを表示することができ、屋外制御盤１０のデザイン性の向上を図ることができる。   Moreover, the thing provided with the light emitting element is considered for the recent photovoltaic power generation panel, for example. Therefore, by attaching a photovoltaic power generation panel having such a light emitting function to the upper surface and side surfaces of the housing 11 or mixing them, the color of the photovoltaic power generation panel can be changed, A pattern, a character, etc. can be displayed on this, and the design property of the outdoor control panel 10 can be improved.

図３に例示する屋外制御盤１０において、上部太陽光発電パネル２０ｕは、筐体１１の上面、より具体的には傾斜枠１４の上部からの離間寸法が北側ほど大きくなった構成となっている。一般的に、屋外に設置される構造物の北側には太陽光が直接的にあたりにくく、従って、北側の空気は、南側の空気に比べ温度が低い傾向がある。この構成例によれば、上部太陽光発電パネル２０ｕは、北側ほど筐体１１の上面、より具体的には傾斜枠１４の上部から離間しているため、北側の低温の空気が上部太陽光発電パネル２０ｕと筐体１１の上面、より具体的には傾斜枠１４の上部との間に流れ込みやすく、従って、上部太陽光発電パネル２０ｕの裏面側ひいては筐体１１内の温度上昇を効率良く抑えることができる。 (Second Embodiment)
In the outdoor control panel 10 illustrated in FIG. 3, the upper photovoltaic power generation panel 20 u has a configuration in which the distance from the upper surface of the housing 11, more specifically, the upper portion of the inclined frame 14, increases toward the north side. . Generally, sunlight is less likely to hit the north side of a structure installed outdoors, and therefore the north side air tends to be lower in temperature than the south side air. According to this configuration example, the upper solar power generation panel 20u is separated from the upper surface of the housing 11 toward the north side, more specifically, from the upper part of the inclined frame 14. It is easy to flow between the panel 20 u and the upper surface of the housing 11, more specifically, the upper part of the inclined frame 14. Therefore, the temperature rise in the rear surface side of the upper solar power generation panel 20 u and thus the housing 11 can be efficiently suppressed. Can do.

また、例えば南中時における南側からの太陽光の照射方向Ｓに対し上部太陽光発電パネル２０ｕの傾斜角度を設置場所の緯度等を加味した最適な角度とすることにより、上部太陽光発電パネル２０ｕに太陽光を効率良く入射させることができ、発電効率の向上を図ることができる。なお、上部太陽光発電パネル２０ｕの法線方向Ｎを中心とする所定の角度範囲α内において太陽光が入射するように上部太陽光発電パネル２０ｕの傾斜角度を調整するとよい。これにより、上部太陽光発電パネル２０ｕの発電量を効率良く上昇させることができる。   Further, for example, by setting the inclination angle of the upper solar power generation panel 20u with respect to the irradiation direction S of sunlight from the south side in the middle of the south to an optimum angle in consideration of the latitude of the installation location, etc., the upper solar power generation panel 20u The sunlight can be efficiently incident on the solar cell, and the power generation efficiency can be improved. Note that the inclination angle of the upper solar power generation panel 20u may be adjusted so that sunlight is incident within a predetermined angle range α centered on the normal direction N of the upper solar power generation panel 20u. Thereby, the electric power generation amount of the upper photovoltaic power generation panel 20u can be raised efficiently.

なお、所定の角度範囲αは、例えば、日本国内において季節により変化する南中時における太陽光の入射角度の変位幅である４０度程で設定するとよい。また、上部太陽光発電パネル２０ｕの傾斜角度、換言すれば、上部太陽光発電パネル２０ｕの法線方向Ｎの指向方向は、太陽光の入射角度が大きくなり、受光効率が高くなり、日照時間が長くなり、発電量が大きくなる、例えば夏季における状況等を考慮して設定するとよい。   In addition, the predetermined angle range α may be set, for example, at about 40 degrees that is the displacement width of the incident angle of sunlight at the time of south and middle that changes depending on the season in Japan. In addition, the inclination angle of the upper photovoltaic panel 20u, in other words, the directivity direction in the normal direction N of the upper photovoltaic panel 20u, the incident angle of sunlight is increased, the light receiving efficiency is increased, and the sunshine time is increased. It may be set in consideration of the situation in the summer when the power generation amount becomes longer and longer.

また、屋外制御盤１０は、例えば、上部太陽光発電パネル２０ｕの南側の端部をヒンジ構造により固定して当該上部太陽光発電パネル２０ｕを回動可能に構成することで、上部太陽光発電パネル２０ｕの傾斜角度を調整可能に構成してもよい。   In addition, the outdoor control panel 10 is configured such that, for example, the upper end photovoltaic panel 20u can be rotated by fixing the south end of the upper photovoltaic panel 20u with a hinge structure. The tilt angle of 20u may be adjustable.

図４に例示する屋外制御盤１０において、側部太陽光発電パネル２０ｅは、筐体１１の側面、この場合、東側の側面からの離間寸法が北側ほど大きくなった構成となっている。また、側部太陽光発電パネル２０ｗは、筐体１１の側面、この場合、西側の側面からの離間寸法が北側ほど大きくなった構成となっている。この構成例によれば、側部太陽光発電パネル２０ｅは、北側ほど筐体１１の側面から開いているため、北側の低温の空気が側部太陽光発電パネル２０ｅと筐体１１の側面との間に流れ込みやすく、従って、側部太陽光発電パネル２０ｅの裏面側ひいては筐体１１内を効率良く冷却することができる。また、側部太陽光発電パネル２０ｗは、北側ほど筐体１１の側面から開いているため、北側の低温の空気が側部太陽光発電パネル２０ｗと筐体１１の側面との間に流れ込みやすく、従って、側部太陽光発電パネル２０ｗの裏面側ひいては筐体１１内を効率良く冷却することができる。 (Third embodiment)
In the outdoor control panel 10 illustrated in FIG. 4, the side photovoltaic power generation panel 20 e has a configuration in which the distance from the side surface of the housing 11, in this case, the east side surface, increases toward the north side. Further, the side photovoltaic power generation panel 20w has a configuration in which the distance from the side surface of the housing 11, in this case, the side surface on the west side, increases toward the north side. According to this configuration example, since the side photovoltaic power generation panel 20e is open from the side surface of the housing 11 toward the north side, the low temperature air on the north side is formed between the side photovoltaic power generation panel 20e and the side surface of the housing 11. Therefore, it is easy to flow in between. Therefore, the back side of the side photovoltaic power generation panel 20e, and thus the inside of the housing 11 can be efficiently cooled. Moreover, since the side solar power generation panel 20w is opened from the side surface of the housing 11 toward the north side, low-temperature air on the north side easily flows between the side solar power generation panel 20w and the side surface of the housing 11, Therefore, the back surface side of the side solar power generation panel 20w and thus the inside of the housing 11 can be efficiently cooled.

また、南側からの太陽光の照射方向に対し側部太陽光発電パネル２０ｅ，２０ｗの傾斜角度を、屋外制御盤１０の強度を損なわない範囲内において最適な角度とすることにより、側部太陽光発電パネル２０ｅ，２０ｗに太陽光を効率良く入射させることができ、発電効率の向上を図ることができる。   In addition, by setting the inclination angle of the side photovoltaic power generation panels 20e and 20w with respect to the irradiation direction of sunlight from the south side to an optimum angle within a range that does not impair the strength of the outdoor control panel 10, the side sunlight Sunlight can be efficiently incident on the power generation panels 20e and 20w, and the power generation efficiency can be improved.

また、屋外制御盤１０は、例えば、側部太陽光発電パネル２０ｅ，２０ｗの南側の端部をヒンジ構造により固定して当該側部太陽光発電パネル２０ｅ，２０ｗを回動可能に構成することで、側部太陽光発電パネル２０ｅ，２０ｗの傾斜角度を調整可能に構成してもよい。   Moreover, the outdoor control panel 10 is configured such that, for example, the south side ends of the side solar power generation panels 20e and 20w are fixed by a hinge structure so that the side solar power generation panels 20e and 20w can be rotated. The inclination angle of the side photovoltaic power generation panels 20e and 20w may be adjustable.

また、屋外制御盤１０の構造上の強度は、直方体形の筐体１１の構造により概ね決まり、太陽光発電パネルが筐体の上面あるいは側面に対して傾斜して突出した状態では、太陽光発電パネルが風圧の影響を受けやすく、従って、例えば支持金具２１を強固にするなどの強度を高めるための対処が必要となる。しかし、太陽光発電パネルの傾斜角度を可動とした構成によれば、例えば風圧に応じて傾斜角度を可動させることで、強度上の課題に対処することができる。   In addition, the structural strength of the outdoor control panel 10 is generally determined by the structure of the rectangular parallelepiped casing 11, and in the state where the photovoltaic power generation panel protrudes obliquely with respect to the upper surface or side surface of the casing, The panel is easily affected by the wind pressure, and therefore, it is necessary to take measures to increase the strength, for example, to strengthen the support fitting 21. However, according to the configuration in which the inclination angle of the photovoltaic power generation panel is movable, for example, by moving the inclination angle in accordance with the wind pressure, it is possible to cope with a problem in strength.

図５に例示する屋外制御盤１０において、側部太陽光発電パネル２０ｓは、筐体１１の側面、この場合、南側の側面からの離間寸法が下側ほど大きくなった構成となっている。また、側部太陽光発電パネル２０ｎは、筐体１１の側面、この場合、北側の側面からの離間寸法が下側ほど大きくなった構成となっている。なお、図示はしないが、側部太陽光発電パネル２０ｅは、筐体１１の側面、この場合、東側の側面からの離間寸法が下側ほど大きくなっており、側部太陽光発電パネル２０ｗは、筐体１１の側面、この場合、西側の側面からの離間寸法が下側ほど大きくなっている。 (Fourth embodiment)
In the outdoor control panel 10 illustrated in FIG. 5, the side photovoltaic power generation panel 20 s has a configuration in which the distance from the side surface of the housing 11, in this case, the south side surface, increases toward the lower side. Further, the side photovoltaic power generation panel 20n has a configuration in which the distance from the side surface of the housing 11, in this case, the side surface on the north side, increases toward the lower side. Although not shown, the side solar power generation panel 20e has a larger distance from the side surface of the housing 11, in this case, the side surface on the east side, and the side solar power generation panel 20w The distance from the side surface of the housing 11, in this case, the side surface on the west side, increases toward the lower side.

一般的に、空気は、温められると上昇するという性質を有する。この構成例によれば、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎと筐体１１の側面との間において、太陽光により温められた空気が下側から入り、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側の空気、つまり、太陽光の直射を受けず比較的低温の空気と混合して上昇しやすく、従って、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎと筐体１１の側面との間における空気の流れが活発となり、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側ひいては筐体１１内を効率良く冷却することができる。このとき、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側の空間は、上側ほど狭くなっているから、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側を上昇する空気の流速は上昇するほど高まり、従って、冷却効果を一層期待することができる。   In general, air has the property of rising when warmed. According to this configuration example, air heated by sunlight enters from the lower side between the side solar power generation panels 20e, 20w, 20s, 20n and the side surface of the casing 11, and the side solar power generation panel Air on the back side of 20e, 20w, 20s, 20n, that is, it is easy to rise by mixing with air of relatively low temperature without receiving direct sunlight, and therefore, the side solar power generation panels 20e, 20w, 20s, 20n And the side surface of the housing 11 become active, and the back side of the side photovoltaic power generation panels 20e, 20w, 20s, and 20n, that is, the inside of the housing 11 can be efficiently cooled. At this time, since the space on the back surface side of the side solar power generation panels 20e, 20w, 20s, and 20n is narrower toward the upper side, the back surface side of the side solar power generation panels 20e, 20w, 20s, and 20n is raised. As the air flow rate increases, the cooling effect can be further expected.

また、特に南側に取り付けられる側部太陽光発電パネル２０ｓについては、南側からの太陽光の照射方向に対する傾斜角度を最適な角度とすることにより、太陽光を効率良く入射させることができ、発電効率の向上を図ることができる。   Moreover, especially about the side photovoltaic power generation panel 20s attached to the south side, by making the inclination angle with respect to the irradiation direction of sunlight from the south side the optimum angle, sunlight can be efficiently incident, and the power generation efficiency Can be improved.

また、屋外制御盤１０は、例えば、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの上側の端部をヒンジ構造により固定して当該側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎを、屋外制御盤１０の強度を損なわない範囲内において回動可能に構成することで、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの傾斜角度を調整可能に構成してもよい。   Moreover, the outdoor control panel 10 fixes the side solar power generation panels 20e, 20w, 20s, and 20n by fixing the upper ends of the side solar power generation panels 20e, 20w, 20s, and 20n with a hinge structure, for example. The tilt angle of the side photovoltaic power generation panels 20e, 20w, 20s, and 20n may be adjustable by configuring the outdoor control panel 10 so as to be rotatable within a range that does not impair the strength of the outdoor control panel 10.

また、屋外制御盤１０によれば、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎが傾斜した状態となっているため、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの表面に付着した汚れを、上方から落ちてくる雨により洗い流しやすくすることができる。側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの表面に汚れが付着した状態では、汚れが付着した部分に太陽光が直接的に入射することができないため、当該部分が発電不能な抵抗体となって発熱してしまう、いわゆるホットスポット現象が生じ得る。そのため、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの表面に付着した汚れを雨を利用して洗い流す構成とすることで、ホットスポット現象の発生を抑えることができる。   Moreover, according to the outdoor control panel 10, since the side solar power generation panels 20e, 20w, 20s, and 20n are inclined, they adhere to the surfaces of the side solar power generation panels 20e, 20w, 20s, and 20n. It is possible to make it easier to wash away the soil by rain falling from above. In the state where dirt is attached to the surface of the side solar power generation panels 20e, 20w, 20s, 20n, since sunlight cannot directly enter the part where the dirt is attached, the resistor cannot generate power. As a result, a so-called hot spot phenomenon that generates heat may occur. Therefore, it is possible to suppress the occurrence of the hot spot phenomenon by adopting a configuration in which the dirt adhering to the surfaces of the side solar power generation panels 20e, 20w, 20s, and 20n is washed away using rain.

図６に例示する屋外制御盤１０は、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎに送風ファン３０を組み込んだ構成である。送風ファン３０は、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側から表面側に向けて送風する。この構成例によれば、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎと筐体１１の側面との間の空気の循環を高めて積極的に排出することができ、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎと筐体１１の側面との間の冷却を効率良く行うことができる。従って、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側ひいては筐体１１内を効率良く冷却することができる。 (Fifth embodiment)
The outdoor control panel 10 illustrated in FIG. 6 has a configuration in which the blower fan 30 is incorporated in the side solar power generation panels 20e, 20w, 20s, and 20n. The blower fan 30 blows air from the back side of the side photovoltaic power generation panels 20e, 20w, 20s, 20n toward the front side. According to this configuration example, air circulation between the side solar power generation panels 20e, 20w, 20s, 20n and the side surface of the housing 11 can be increased and actively discharged, and the side solar power generation Cooling between the panels 20e, 20w, 20s, and 20n and the side surface of the housing 11 can be performed efficiently. Therefore, the back surface side of the side solar power generation panels 20e, 20w, 20s, and 20n, and thus the inside of the housing 11 can be efficiently cooled.

なお、太陽光発電パネル２０に対する送風ファン３０の組み込み位置は、適宜変更して実施することができる。図７に例示するように、太陽光発電パネル２０の中央部に送風ファン３０を組み込んだ構成例によれば、太陽光発電パネル２０の裏面側全体から均等に空気を排出することができ、太陽光発電パネル２０の裏面側全体を効率良く冷却することができる。また、一般的に、温められた空気は上昇しやすいため、図８に例示するように、太陽光発電パネル２０の上部に送風ファン３０を組み込むことにより、太陽光発電パネル２０の裏面側において温められて上昇した空気を表面側に排出しやすくすることができ、太陽光発電パネル２０の裏面側を効率良く冷却することができる。   In addition, the installation position of the ventilation fan 30 with respect to the photovoltaic power generation panel 20 can be changed and implemented suitably. As illustrated in FIG. 7, according to the configuration example in which the blower fan 30 is incorporated in the central portion of the photovoltaic power generation panel 20, air can be evenly discharged from the entire back surface side of the photovoltaic power generation panel 20. The entire back surface side of the photovoltaic panel 20 can be efficiently cooled. In general, since warmed air is likely to rise, as shown in FIG. 8, by incorporating a blower fan 30 in the upper part of the photovoltaic power generation panel 20, warming is performed on the back side of the photovoltaic power generation panel 20. The air thus raised can be easily discharged to the front surface side, and the back surface side of the photovoltaic power generation panel 20 can be efficiently cooled.

なお、図示はしないが、特に側部太陽光発電パネル２０ｅ，２０ｗについては、より南側に送風ファン３０を組み込む構成としてもよい。即ち、冷たい北風が入りやすい北側に比べて空気の温度が上昇しやすい南側に送風ファン３０を組み込むことにより、温められた空気を側部太陽光発電パネル２０ｅ，２０ｗの裏面側から効率良く排出することができ、側部太陽光発電パネル２０ｅ，２０ｗの裏面側を効率良く冷却することができる。また、送風ファン３０は、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの全てに組み込む必要はなく、例えば温度が上昇しやすい側部太陽光発電パネル２０ｓに組み込むなど、少なくとも１つの側部太陽光発電パネルに組み込む構成としてもよい。また、送風ファン３０は、上部太陽光発電パネル２０ｕに組み込んでもよい。   In addition, although not shown in figure, especially about the side part photovoltaic power generation panels 20e and 20w, it is good also as a structure which incorporates the ventilation fan 30 more south. That is, by incorporating the blower fan 30 on the south side where the temperature of the air is likely to rise compared with the north side where the cold north wind is likely to enter, the warmed air is efficiently discharged from the back side of the side photovoltaic power generation panels 20e and 20w. It is possible to cool the back side of the side photovoltaic power generation panels 20e, 20w efficiently. Further, the blower fan 30 does not have to be incorporated in all of the side photovoltaic power generation panels 20e, 20w, 20s, and 20n. For example, the ventilation fan 30 is incorporated in the side photovoltaic power generation panel 20s that easily rises in temperature. It is good also as a structure built in a photovoltaic power generation panel. The blower fan 30 may be incorporated in the upper solar power generation panel 20u.

また、屋外制御盤１０は、送風ファン３０の全面に白色系の塗装を施した構成としてもよい。この構成によれば、送風ファン３０に入射する太陽光を白色系の塗装により反射させることができ、送風ファン３０の温度上昇を抑えることができる。なお、屋外制御盤１０は、送風ファン３０の一部、例えば表面または裏面に白色系の塗装を施した構成としてもよい。   The outdoor control panel 10 may have a configuration in which white paint is applied to the entire surface of the blower fan 30. According to this structure, the sunlight which injects into the ventilation fan 30 can be reflected by white-type coating, and the temperature rise of the ventilation fan 30 can be suppressed. The outdoor control panel 10 may have a configuration in which a part of the blower fan 30, for example, the front surface or the back surface is painted white.

また、屋外制御盤１０は、筐体１１内の温度または筐体１１外の南側の面の温度を検知する温度検知センサを備え、この温度検知センサによる検知温度が所定値よりも高くなったことを条件に送風ファン３０を駆動するように構成するとよい。この構成によれば、送付ファン３０を無用に連続運転してしまうことを回避することができる。
また、送風ファン３０を駆動するための電源は、上部太陽光発電パネル２０ｕや側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎが発生する電気を利用するとよい。 In addition, the outdoor control panel 10 includes a temperature detection sensor that detects the temperature inside the casing 11 or the temperature of the south surface outside the casing 11, and the temperature detected by the temperature detection sensor is higher than a predetermined value. It is good to comprise so that the ventilation fan 30 may be driven on condition. According to this configuration, it is possible to avoid unnecessarily continuously operating the sending fan 30.
Moreover, the power source for driving the blower fan 30 may use electricity generated by the upper solar power generation panel 20u and the side solar power generation panels 20e, 20w, 20s, and 20n.

図９に例示する屋外制御盤１０において、送風ファン３０は、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの裏面側から表面側に空気を排出する排気方向Ａ１および側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの表面側から裏面側に空気を吸引する吸気方向Ａ２に送風方向を切り換え可能に構成されている。また、屋外制御盤１０は、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの発電量を検知する図示しない発電量検知センサを備えている。屋外制御盤１０の動作全般を制御する図示しない制御ユニットは、発電量検知センサによる検知結果に基づいて、側部太陽光発電パネル２０ｅ，２０ｗ，２０ｓ，２０ｎの発電量をそれぞれ特定可能となっている。 (Sixth embodiment)
In the outdoor control panel 10 illustrated in FIG. 9, the blower fan 30 includes an exhaust direction A1 for discharging air from the back side of the side solar power generation panels 20e, 20w, 20s, and 20n to the front side, and the side solar power generation panel. 20e, 20w, 20s, 20n is configured to be able to switch the blowing direction to the intake direction A2 for sucking air from the front side to the back side. Moreover, the outdoor control panel 10 includes a power generation amount detection sensor (not shown) that detects the power generation amount of the side solar power generation panels 20e, 20w, 20s, and 20n. A control unit (not shown) that controls the overall operation of the outdoor control panel 10 can specify the power generation amount of the side solar power generation panels 20e, 20w, 20s, and 20n based on the detection result by the power generation detection sensor. Yes.

そして、制御ユニットは、筐体１１の側面において、相互に対向する２つの側部太陽光発電パネルの発電量を比較し、その比較結果に基づいて、送風ファン３０の送風方向を切り換える。即ち、制御ユニットは、相互に対向する側部太陽光発電パネル２０ｅと側部太陽光発電パネル２０ｗの発電量を比較する。また、制御ユニットは、相互に対向する側部太陽光発電パネル２０ｓと側部太陽光発電パネル２０ｎの発電量を比較する。そして、制御ユニットは、相互に対向する２つの側部太陽光発電パネルのうち、より発電量が小さい側部太陽光発電パネルの送風ファン３０の送風方向を吸気方向Ａ２に切り換える。また、制御ユニットは、相互に対向する２つの側部太陽光発電パネルのうち、より発電量が大きい側部太陽光発電パネルの送風ファン３０の送風方向を排気方向Ａ１に切り換える。   And a control unit compares the electric power generation amount of the two side part photovoltaic power generation panels which mutually oppose on the side surface of the housing | casing 11, and switches the ventilation direction of the ventilation fan 30 based on the comparison result. That is, the control unit compares the power generation amounts of the side photovoltaic power generation panel 20e and the side photovoltaic power generation panel 20w facing each other. Further, the control unit compares the power generation amounts of the side photovoltaic power generation panel 20s and the side photovoltaic power generation panel 20n facing each other. Then, the control unit switches the blowing direction of the blower fan 30 of the side photovoltaic power generation panel having the smaller power generation amount to the intake direction A2 among the two side photovoltaic panels facing each other. Moreover, a control unit switches the ventilation direction of the ventilation fan 30 of a side photovoltaic power generation panel with a larger electric power generation amount to the exhaust direction A1 among the two side photovoltaic power generation panels facing each other.

図１０に例示する「朝」の状態では、東側からの太陽光が側部太陽光発電パネル２０ｅにあたって当該側部太陽光発電パネル２０ｅの発電量が上昇しやすく、一方、側部太陽光発電パネル２０ｗには太陽光が殆どあたらず当該側部太陽光発電パネル２０ｗの発電量は上昇しにくい。そのため、より発電量が小さくなる側部太陽光発電パネル２０ｗの送風ファン３０の送風方向は吸気方向Ａ２に切り換えられ、一方、より発電量が大きくなる側部太陽光発電パネル２０ｅの送風ファン３０の送風方向は排気方向Ａ１に切り換えられる。   In the “morning” state illustrated in FIG. 10, the amount of power generated by the side solar power generation panel 20 e easily rises when the sunlight from the east side enters the side solar power generation panel 20 e, while the side solar power generation panel 20w hardly receives sunlight, and the power generation amount of the side solar power generation panel 20w hardly increases. Therefore, the blowing direction of the blower fan 30 of the side photovoltaic power generation panel 20w where the power generation amount becomes smaller is switched to the intake direction A2, while the blowing fan 30 of the side solar power generation panel 20e where the power generation amount becomes larger. The blowing direction is switched to the exhaust direction A1.

より発電量が大きくなる側部太陽光発電パネル２０ｅには、より多くの太陽光があたっており、従って、温度も上昇しやすい。このような側部太陽光発電パネル２０ｅの送風ファン３０の送風方向を排気方向Ａ１に切り換えることで、当該側部太陽光発電パネル２０ｅの裏面側の熱い空気を積極的に排出して温度上昇作用を低減することができ、当該側部太陽光発電パネル２０ｅひいては筐体１１内を効率良く冷却することができる。   The side photovoltaic power generation panel 20e having a larger power generation amount is exposed to more sunlight, and therefore the temperature is likely to rise. By switching the blowing direction of the blower fan 30 of the side solar power generation panel 20e to the exhaust direction A1, hot air on the back side of the side solar power generation panel 20e is actively discharged to increase the temperature. And the inside of the casing 11 can be efficiently cooled.

一方、より発電量が小さくなる側部太陽光発電パネル２０ｗには、太陽光が殆どあたっておらず、従って、温度も上昇しにくい。このような側部太陽光発電パネル２０ｗの送風ファン３０の送風方向を吸気方向Ａ２に切り換えることで、当該側部太陽光発電パネル２０ｗの表面側の冷たい空気を積極的に吸気することができ、当該側部太陽光発電パネル２０ｗひいては筐体１１内を効率良く冷却することができる。   On the other hand, the side solar power generation panel 20w having a smaller power generation amount is hardly exposed to sunlight, and therefore the temperature is hardly increased. By switching the blowing direction of the blower fan 30 of the side solar power generation panel 20w to the intake direction A2, it is possible to positively inhale the cold air on the surface side of the side solar power generation panel 20w, The side solar power generation panel 20w and thus the inside of the housing 11 can be efficiently cooled.

また、図１１に例示する「昼」の状態では、南側からの太陽光が側部太陽光発電パネル２０ｓにあたって当該側部太陽光発電パネル２０ｓの発電量が上昇しやすく、一方、側部太陽光発電パネル２０ｎには太陽光が殆どあたらず当該側部太陽光発電パネル２０ｎの発電量は上昇しにくい。そのため、より発電量が小さくなる側部太陽光発電パネル２０ｎの送風ファン３０の送風方向は吸気方向Ａ２に切り換えられ、一方、より発電量が大きくなる側部太陽光発電パネル２０ｓの送風ファン３０の送風方向は排気方向Ａ１に切り換えられる。なお、図１１に例示する「昼」の状態では、図１０に例示する「朝」の状態と同様に、側部太陽光発電パネル２０ｅの送風ファン３０の送風方向は排気方向Ａ１に切り換えた状態を継続し、側部太陽光発電パネル２０ｗの送風ファン３０の送風方向は吸気方向Ａ２に切り換えた状態を継続するとよい。   Further, in the “daytime” state illustrated in FIG. 11, the amount of power generated by the side photovoltaic power generation panel 20 s is likely to increase when the sunlight from the south side enters the side photovoltaic power generation panel 20 s, while the side sunlight. The power generation panel 20n hardly receives sunlight, and the power generation amount of the side solar power generation panel 20n hardly increases. Therefore, the blowing direction of the blower fan 30 of the side photovoltaic power generation panel 20n where the power generation amount becomes smaller is switched to the intake direction A2, while the blowing fan 30 of the side solar power generation panel 20s where the power generation amount becomes larger. The blowing direction is switched to the exhaust direction A1. In the “daytime” state illustrated in FIG. 11, the air blowing direction of the blower fan 30 of the side photovoltaic power generation panel 20 e is switched to the exhaust direction A1 as in the “morning” state illustrated in FIG. 10. It is good to continue the state which switched the ventilation direction of the ventilation fan 30 of the side photovoltaic power generation panel 20w to the intake direction A2.

より発電量が大きくなる側部太陽光発電パネル２０ｓには、より多くの太陽光があたっており、従って、温度も上昇しやすい。このような側部太陽光発電パネル２０ｓの送風ファン３０の送風方向を排気方向Ａ１に切り換えることで、当該側部太陽光発電パネル２０ｓの裏面側の熱い空気を積極的に排出することができ、当該側部太陽光発電パネル２０ｓひいては筐体１１内を効率良く冷却することができる。   The side photovoltaic power generation panel 20s where the power generation amount becomes larger is exposed to more sunlight, and therefore the temperature is likely to rise. By switching the blowing direction of the blower fan 30 of the side solar power generation panel 20s to the exhaust direction A1, hot air on the back side of the side solar power generation panel 20s can be actively discharged, The side solar power generation panel 20s and thus the inside of the housing 11 can be efficiently cooled.

一方、より発電量が小さくなる側部太陽光発電パネル２０ｎには、太陽光が殆どあたっておらず、従って、温度も上昇しにくい。このような側部太陽光発電パネル２０ｎの送風ファン３０の送風方向を吸気方向Ａ２に切り換えることで、当該側部太陽光発電パネル２０ｎの表面側の冷たい空気を積極的に吸気することができ、当該側部太陽光発電パネル２０ｎひいては筐体１１内を効率良く冷却することができる。   On the other hand, the side solar power generation panel 20n having a smaller power generation amount is hardly exposed to sunlight, and therefore the temperature is hardly increased. By switching the blowing direction of the blower fan 30 of the side solar power generation panel 20n to the intake direction A2, it is possible to positively inhale the cold air on the surface side of the side solar power generation panel 20n, The side solar power generation panel 20n and thus the inside of the housing 11 can be efficiently cooled.

また、図１２に例示する「夕方」または「夜」の状態では、西側からの太陽光が側部太陽光発電パネル２０ｗにあたって当該側部太陽光発電パネル２０ｗの発電量が上昇しやすく、一方、側部太陽光発電パネル２０ｅには太陽光が殆どあたらず当該側部太陽光発電パネル２０ｅの発電量は上昇しにくい。そのため、より発電量が小さくなる側部太陽光発電パネル２０ｅの送風ファン３０の送風方向は吸気方向Ａ２に切り換えられ、一方、より発電量が大きくなる側部太陽光発電パネル２０ｗの送風ファン３０の送風方向は排気方向Ａ１に切り換えられる。なお、図１２に例示する「夕方」または「夜」の状態では、側部太陽光発電パネル２０ｓの送風ファン３０の送風方向は、図１１に例示する「昼」の状態と同様に、排気方向Ａ１に切り換えた状態を継続し、側部太陽光発電パネル２０ｎの送風ファン３０の送風方向は、吸気方向Ａ２に切り換えた状態を継続するとよい。   Further, in the “evening” or “night” state illustrated in FIG. 12, the amount of power generated by the side photovoltaic power generation panel 20 w is likely to increase when the sunlight from the west side enters the side photovoltaic power generation panel 20 w, The side solar power generation panel 20e is hardly exposed to sunlight, and the power generation amount of the side solar power generation panel 20e is unlikely to increase. Therefore, the blowing direction of the blower fan 30 of the side solar power generation panel 20e with a smaller power generation amount is switched to the intake direction A2, while the blower fan 30 of the side solar power generation panel 20w with a larger power generation amount is switched. The blowing direction is switched to the exhaust direction A1. In the “evening” or “night” state illustrated in FIG. 12, the air blowing direction of the blower fan 30 of the side photovoltaic power generation panel 20 s is the exhaust direction as in the “daytime” state illustrated in FIG. 11. The state switched to A1 may be continued, and the blowing direction of the blower fan 30 of the side photovoltaic power generation panel 20n may be continued to the state switched to the intake direction A2.

より発電量が大きくなる側部太陽光発電パネル２０ｗには、より多くの太陽光があたっており、従って、温度も上昇しやすい。このような側部太陽光発電パネル２０ｗの送風ファン３０の送風方向を排気方向Ａ１に切り換えることで、当該側部太陽光発電パネル２０ｗの裏面側の熱い空気を積極的に排出することができ、当該側部太陽光発電パネル２０ｗひいては筐体１１内を効率良く冷却することができる。   The side solar power generation panel 20w with a larger power generation amount is exposed to more sunlight, and therefore the temperature is likely to rise. By switching the blowing direction of the blower fan 30 of the side solar power generation panel 20w to the exhaust direction A1, hot air on the back side of the side solar power generation panel 20w can be positively discharged, The side solar power generation panel 20w and thus the inside of the housing 11 can be efficiently cooled.

一方、より発電量が小さくなる側部太陽光発電パネル２０ｅには、太陽光が殆どあたっておらず、従って、温度も上昇しにくい。このような側部太陽光発電パネル２０ｅの送風ファン３０の送風方向を吸気方向Ａ２に切り換えることで、当該側部太陽光発電パネル２０ｅの表面側の冷たい空気を積極的に吸気することができ、当該側部太陽光発電パネル２０ｅひいては筐体１１内を効率良く冷却することができる。   On the other hand, the side solar power generation panel 20e having a smaller power generation amount is hardly exposed to sunlight, and therefore the temperature is hardly increased. By switching the blowing direction of the blower fan 30 of the side solar power generation panel 20e to the intake direction A2, it is possible to positively inhale cold air on the surface side of the side solar power generation panel 20e, The side solar power generation panel 20e and thus the inside of the housing 11 can be efficiently cooled.

なお、屋外制御盤１０は、相互に対向する太陽光発電パネルの発電量の差が所定量以上となっていることを条件に、発電量に基づいて送風ファン３０の送風方向を切り換えるように構成してもよい。また、屋外制御盤１０は、例えば「朝」、「昼」、「夕方」、「夜」などの時間帯を問わず、太陽光発電パネルの各発電量自体が所定量よりも大きくなっていること、あるいは、相互に対向する太陽光発電パネルの発電量の差が所定量以上となっていることを条件に、発電量の大きい太陽光発電パネルの送風ファン３０の送風方向を、吸気方向から排気方向に切り換える構成としてもよい。つまり、屋外制御盤１０は、筐体１１周辺の温かい空気を優先して積極的に排気する構成とするとよい。   The outdoor control panel 10 is configured to switch the blowing direction of the blower fan 30 based on the power generation amount on the condition that the difference in the power generation amount between the photovoltaic power generation panels facing each other is a predetermined amount or more. May be. In addition, the outdoor control panel 10 is configured such that each power generation amount of the photovoltaic power generation panel is larger than a predetermined amount regardless of time periods such as “morning”, “daytime”, “evening”, and “night”. Alternatively, on the condition that the difference in the power generation amount of the photovoltaic power generation panels facing each other is a predetermined amount or more, the blowing direction of the blower fan 30 of the solar power generation panel having a large power generation amount is changed from the intake direction. It is good also as a structure switched to an exhaust direction. That is, the outdoor control panel 10 may be configured to positively exhaust the warm air around the casing 11 with priority.

また、例えば真夏の南中時においては、屋外制御盤１０の周囲の空気は、何れの方角においても高温となり、方角による空気の温度差が少なくなる。換言すれば、屋外制御部１０の周囲に、吸気したい冷たい空気が存在しない状態となる。そのため、このような場合には、屋外制御盤１０は、発電量の小さい太陽光発電パネルの送風ファン３０であっても、その送風方向を、吸気方向から排気方向に切り換える構成としてもよい。   Further, for example, in the middle of summer in the middle of summer, the air around the outdoor control panel 10 becomes high in any direction, and the temperature difference of the air due to the direction is reduced. In other words, there is no cold air to be sucked around the outdoor control unit 10. Therefore, in such a case, the outdoor control panel 10 may be configured to switch the blowing direction from the intake direction to the exhaust direction even if it is the blower fan 30 of the photovoltaic power generation panel with a small power generation amount.

（第７実施形態）
図１３および図１４に例示する屋外制御盤１０において、側部太陽光発電パネル２０は、フレキシブルに変形可能なフィルム状に構成されている。そして、側部太陽光発電パネル２０の内部には、当該側部太陽光発電パネル２０に沿ってバイメタル４０が組み込まれている。バイメタル４０は、熱膨張率が異なる２種類の金属板を貼り合わせた構成であり、熱が与えられると曲がるように変形する。この場合、バイメタル４０は、熱膨張率が大きい金属板４０ａと、この金属板４０ａよりも熱膨張率が小さい金属板４０ｂと、を貼り合わせた構成である。そして、バイメタル４０は、金属板４０ａを筐体１１側である内側、金属板４０ｂを筐体１１側とは反対側である外側に配置した構成となっている。このように構成されるバイメタル４０は、熱が与えられると、熱膨張率が大きい内側の金属板４０ａが、熱膨張率が小さい外側の金属板４０ｂよりも膨張し、これにより、筐体１１の側面に沿って上下方向に直線状に延びる状態、つまり、熱により変形していない非変形状態から、筐体１１の側面から離間するように外側に反り上がって曲がった状態、つまり、熱により変形した変形状態に移行する。 (Seventh embodiment)
In the outdoor control panel 10 illustrated in FIGS. 13 and 14, the side photovoltaic power generation panel 20 is configured in a film shape that can be flexibly deformed. A bimetal 40 is incorporated in the side solar power generation panel 20 along the side solar power generation panel 20. The bimetal 40 has a configuration in which two types of metal plates having different coefficients of thermal expansion are bonded together, and is deformed so as to bend when heat is applied. In this case, the bimetal 40 has a configuration in which a metal plate 40a having a large thermal expansion coefficient and a metal plate 40b having a smaller thermal expansion coefficient than the metal plate 40a are bonded together. The bimetal 40 has a configuration in which the metal plate 40a is disposed on the inner side which is the housing 11 side, and the metal plate 40b is disposed on the outer side which is the opposite side to the housing 11 side. In the bimetal 40 configured as described above, when heat is applied, the inner metal plate 40a having a large coefficient of thermal expansion expands more than the outer metal plate 40b having a small coefficient of thermal expansion. From a state extending linearly in the vertical direction along the side surface, that is, from a non-deformed state that is not deformed by heat, a state in which it is warped outward and curved away from the side surface of the housing 11, that is, deformed by heat. Transition to the deformed state.

また、屋外制御盤１０は、送風ファン３０の通電路を開閉する通電路開閉装置５０を備える。通電路開閉装置５０は、固定接点５０ａ、可動接点５０ｂ、スプリング５０ｃを備える。可動接点５０ｂは、可動接点駆動軸５０ｄに連結されている。可動接点駆動軸５０ｄは、矢印Ｂ１，Ｂ２方向に往復移動可能に構成されている。可動接点５０ｂは、可動接点駆動軸５０ｄの往復移動に伴い、固定接点５０ａに接触した接触状態と固定接点５０ａから離間した非接触状態とに切り換わる。可動接点５０ｂが固定接点５０ａに接触した接触状態では、送風ファン３０の通電路が閉路されて送風ファン３０が駆動される。一方、可動接点５０ｂが固定接点５０ａから離間した非接触状態では、送風ファン３０の通電路が開路されて送風ファン３０の駆動が停止される。   Moreover, the outdoor control panel 10 includes an energization path opening / closing device 50 that opens and closes the energization path of the blower fan 30. The energization path switching device 50 includes a fixed contact 50a, a movable contact 50b, and a spring 50c. The movable contact 50b is connected to the movable contact drive shaft 50d. The movable contact drive shaft 50d is configured to reciprocate in the directions of arrows B1 and B2. The movable contact 50b switches between a contact state in contact with the fixed contact 50a and a non-contact state separated from the fixed contact 50a as the movable contact drive shaft 50d reciprocates. When the movable contact 50b is in contact with the fixed contact 50a, the energization path of the blower fan 30 is closed and the blower fan 30 is driven. On the other hand, in the non-contact state where the movable contact 50b is separated from the fixed contact 50a, the energization path of the blower fan 30 is opened and the drive of the blower fan 30 is stopped.

バイメタル４０が非変形状態になっている場合には、側部太陽光発電パネル２０の先端部、この場合、下端部が可動接点駆動軸５０ｄを矢印Ｂ１方向に押し込む。これにより、可動接点５０ｂは、固定接点５０ａから離間した非接触状態となり、送風ファン３０は、通電路が開路されて駆動が停止される。そして、バイメタルが変形状態になると、側部太陽光発電パネル２０の先端部が可動接点駆動軸５０ｄから離間し、これに伴い、可動接点駆動軸５０ｄは、スプリング５０ｃの付勢力により矢印Ｂ２方向に移動する。これにより、可動接点５０ｂは、固定接点５０ａに接触した接触状態となり、送風ファン３０は、通電路が閉路されて駆動される。   When the bimetal 40 is in an undeformed state, the tip of the side photovoltaic power generation panel 20, in this case, the lower end pushes the movable contact drive shaft 50 d in the direction of arrow B <b> 1. As a result, the movable contact 50b is brought into a non-contact state separated from the fixed contact 50a, and the blower fan 30 is opened and the drive is stopped. When the bimetal is deformed, the tip of the side photovoltaic power generation panel 20 is separated from the movable contact drive shaft 50d, and accordingly, the movable contact drive shaft 50d is moved in the direction of the arrow B2 by the urging force of the spring 50c. Moving. As a result, the movable contact 50b comes into contact with the fixed contact 50a, and the blower fan 30 is driven with the energization path closed.

この構成によれば、側部太陽光発電パネル２０に太陽光が入射して当該側部太陽光発電パネル２０ひいては筐体１１内の温度が上昇しやすい環境になると、熱により側部太陽光発電パネル２０が変形状態となり、これにより、送風ファン３０を自動的に駆動させることができる。一方、側部太陽光発電パネル２０に太陽光が入射せず当該側部太陽光発電パネル２０ひいては筐体１１内の温度が上昇しにくい環境になると、側部太陽光発電パネル２０が非変形状態となり、これにより、送風ファン３０の駆動を自動的に停止させることができる。よって、送風ファン３０の駆動制御を簡素化することができる。   According to this configuration, when sunlight enters the side solar power generation panel 20 and the temperature in the side solar power generation panel 20 and thus the casing 11 is likely to rise, the side solar power generation is caused by heat. The panel 20 will be in a deformation | transformation state and, thereby, the ventilation fan 30 can be driven automatically. On the other hand, when the sunlight does not enter the side solar power generation panel 20 and the environment in which the side solar power generation panel 20 and thus the temperature inside the housing 11 hardly rises is increased, the side solar power generation panel 20 is not deformed. Thus, the driving of the blower fan 30 can be automatically stopped. Therefore, drive control of the blower fan 30 can be simplified.

なお、通電路開閉装置５０は、例えばバイメタル４０の下端部の位置を検知する位置センサを備え、バイメタル４０の下端部までの距離が所定距離よりも短くなった場合に送風ファン３０の駆動を停止し、バイメタル４０の下端部までの距離が所定距離よりも長くなった場合に送風ファン３０を自動的に駆動させる構成としてもよい。   The energization path opening / closing device 50 includes, for example, a position sensor that detects the position of the lower end portion of the bimetal 40, and stops driving the blower fan 30 when the distance to the lower end portion of the bimetal 40 becomes shorter than a predetermined distance. And it is good also as a structure which drives the ventilation fan 30 automatically, when the distance to the lower end part of the bimetal 40 becomes longer than predetermined distance.

また、通電路開閉装置５０は、筐体１１に外付けする構成としてもよいし、筐体１１内に内蔵する構成としてもよい。また、通電路開閉装置５０は、バイメタル４０あるいは太陽光発電パネルに外付けする構成としてもよいし、バイメタル４０内あるいは太陽光発電パネル内に組み込む構成としてもよい。   The energization path opening / closing device 50 may be externally attached to the housing 11 or may be built in the housing 11. Further, the energization path switching device 50 may be configured to be externally attached to the bimetal 40 or the photovoltaic power generation panel, or may be configured to be incorporated in the bimetal 40 or the photovoltaic power generation panel.

バイメタル４０および当該バイメタル４０を備える太陽光発電パネルは、屋外制御盤１０の強度を損なわない範囲で、各部の寸法、形状を変更することができる。また、支持金具２１の位置は、屋外制御盤１０の強度を損なわない範囲で変更することができる。また、太陽光発電パネルの外枠は、僅かな変形が可能であるが基本的には変形不能な構成とし、内部のバイメタル４０の変形に伴い、太陽光発電パネルが僅かに変形する構成としてもよい。   The bimetal 40 and the photovoltaic power generation panel including the bimetal 40 can change the size and shape of each part within a range that does not impair the strength of the outdoor control panel 10. In addition, the position of the support bracket 21 can be changed within a range that does not impair the strength of the outdoor control panel 10. Further, the outer frame of the photovoltaic power generation panel can be slightly deformed but basically cannot be deformed, and the photovoltaic power generation panel may be slightly deformed as the internal bimetal 40 is deformed. Good.
