Description

本発明は、太陽光を受けて発電する太陽電池を用いた太陽光発電装置に関し、特に、既設ビルの屋上等の平坦面に設置される太陽光発電装置に関する。   The present invention relates to a solar power generation apparatus using a solar cell that generates power by receiving sunlight, and more particularly to a solar power generation apparatus installed on a flat surface such as a rooftop of an existing building.

光エネルギーを利用した太陽光発電装置は、地球環境問題から注目されていて、その利用が推奨されている。太陽光発電装置をビルの屋上等の平坦な面に設置する場合、所定の限られた設置面積に対して、太陽光の受光面をできるだけ大きくとれるように、太陽電池パネルは、通常、地表に向けて傾斜するように取り付けられている（例えば、特許文献１，２参照）。   Photovoltaic power generation devices using light energy are attracting attention due to global environmental problems, and their use is recommended. When installing a photovoltaic power generation device on a flat surface such as the rooftop of a building, the solar panel is usually placed on the ground surface so that the solar light receiving surface can be as large as possible for a given limited installation area. It is attached so that it inclines toward (for example, refer patent document 1, 2).

図５は、上記特許文献に開示の太陽光発電装置を模擬的に示したものである。図５（Ａ）に示すように、太陽光発電装置１は、例えば、コンクリート等で形成された複数の支持台２のそれぞれに支柱３を固定し、支柱３の上端に枠体４を取付け固定し、枠体４の上面に太陽電池パネル５を取付けて構成される。枠体３は、地表に向けて傾斜するように、前部側の支柱一と後部側の支柱の長さを異ならせている。   FIG. 5 schematically shows the solar power generation apparatus disclosed in the above-mentioned patent document. As shown in FIG. 5 (A), the solar power generation device 1 fixes the column 3 to each of a plurality of support bases 2 made of, for example, concrete, and attaches and fixes the frame 4 to the upper end of the column 3 The solar cell panel 5 is attached to the upper surface of the frame 4. The frame 3 has different lengths of the front-side column and the rear-side column so as to incline toward the ground surface.

特開平８−２７４３６４号公報JP-A-8-274364 特開平１１―３４０４９１号公報JP-A-11-340491

図５に示すような構成の太陽光発電装置１は、図６に示すような形態で、太陽電池パネルの背面側から風による風圧を受ける。パネル背面の風圧は、傾斜した枠体４および太陽電池パネル５を上方に押し上げるように作用し、太陽電池パネルを取付け固定している枠体４を、支柱３から外そうとする力が働く。そして、枠体４が固定されている支柱４は、支持台２と共に上方に浮き上がるような作用を受ける。   The solar power generation device 1 configured as shown in FIG. 5 receives wind pressure from the wind from the back side of the solar cell panel in the form as shown in FIG. The wind pressure on the back surface of the panel acts to push up the inclined frame body 4 and the solar cell panel 5, and a force acts to remove the frame body 4 to which the solar cell panel is attached and fixed from the column 3. And the support | pillar 4 to which the frame 4 is being fixed receives the effect | action which floats upwards with the support stand 2. FIG.

したがって、パネル背面に上記のように風圧を受けた場合、太陽電池パネル５と共に枠体４が押し倒されたり飛ばされないようにするには、支柱３にしっかり固定されていることに加えて、支柱３を保持固定する支持台２が容易に浮き上がったり、動かされないようにされている必要がある。新築のビルの場合は、支持台をビル屋上の壁面と一体に形成することが可能であるが、既設のビルでの場合は、支持台を屋上面に載置する形態となるので、コンクリートブロックに重量のある大きいものを用いる必要がある。大きいコンクリートブロックは、クレーンを用いて屋上に吊り上げることになるが、使用するクレーンも大型となるので、支持台２には、できるだけ小さい軽量のコンクリートブロックを用いることが要望されている。   Therefore, in order to prevent the frame body 4 from being pushed down or blown together with the solar cell panel 5 when the wind pressure is applied to the back surface of the panel as described above, in addition to being firmly fixed to the support column 3, the support column 3. It is necessary that the support 2 for holding and fixing is not easily lifted or moved. In the case of a newly built building, it is possible to form the support stand integrally with the wall surface of the building roof. However, in the case of an existing building, the support stand is placed on the top surface of the building. It is necessary to use a large and heavy one. A large concrete block is lifted on the roof using a crane. However, since the crane to be used is also large, it is desired to use a lightweight concrete block as small as possible for the support base 2.

本発明は、上述した実情に鑑みてなされたもので、比較的に小さい軽量の支持台を用いて支持することができ、風圧により前方に倒れたり、飛ばされることのない構造の太陽光発電装置の提供を目的とする。   The present invention has been made in view of the above-described circumstances, and can be supported by using a relatively small and lightweight support base and has a structure that does not fall forward or be blown away by wind pressure. The purpose is to provide.

本発明による太陽光発電装置は、複数の支持台と、該支持台に下端が固定された支柱と、該支柱により地表に対して所定の傾斜を持たせて固定された枠体と、該枠体に設置された太陽電池パネルと、を備えた太陽光発電装置であって、太陽電池パネルが設置される背面側で、枠体の上下方向の途中位置から地表に向けて、枠体の傾斜方向とは反対の方向に傾斜させた風圧反力板が取り付けられていることを特徴とする。
また、風圧反力板の上端側に、水平方向に風抜け用のスロット孔を形成することにより、背面側に当たる風を通り抜かせて、風圧を軽減させるようにすることができる。なお、風圧反力板の上端は枠体に当接させて固定され、下端は支持台で固定するのが好ましい。 A photovoltaic power generation apparatus according to the present invention includes a plurality of support bases, a support column having a lower end fixed to the support table, a frame body fixed with a predetermined inclination with respect to the ground surface by the support column, and the frame A solar power generation device provided with a solar cell panel installed on the body, and on the back side where the solar cell panel is installed, the frame body is inclined from the middle position in the vertical direction of the frame body to the ground surface. A wind pressure reaction force plate inclined in a direction opposite to the direction is attached.
In addition, by forming a wind hole slot hole in the horizontal direction on the upper end side of the wind pressure reaction force plate, it is possible to reduce the wind pressure by passing the wind hitting the back side. In addition, it is preferable that the upper end of the wind pressure reaction force plate is fixed in contact with the frame, and the lower end is fixed by a support base.

本発明の太陽光発電装置によれば、風圧反力板により背面に受ける風圧の一部は、装置を下方に押し下げるように作用させることができ、太陽光発電装置に前方に倒したり、飛ばされるのを抑制することができる。   According to the photovoltaic power generation apparatus of the present invention, a part of the wind pressure received on the back surface by the wind pressure reaction plate can be acted so as to push the apparatus downward, and the photovoltaic power generation apparatus falls forward or is blown away. Can be suppressed.

図１，２により本発明の実施の形態を説明する。図１（Ａ）は、本発明による太陽光発電装置を前面側から見た図、図１（Ｂ）は背面から見た図、図２は太陽電池パネルが取り除かれた状態を示す図である。図中、１１は太陽光発電装置、１２支持台、１３は支柱、１４は枠体、１５は太陽電池パネル、１６は風圧反力板、１７はスロット孔を示す。   An embodiment of the present invention will be described with reference to FIGS. 1A is a view of a photovoltaic power generation apparatus according to the present invention as seen from the front side, FIG. 1B is a view as seen from the back side, and FIG. 2 is a view showing a state where the solar cell panel is removed. . In the figure, 11 is a solar power generation device, 12 supports, 13 is a support, 14 is a frame, 15 is a solar cell panel, 16 is a wind pressure reaction plate, and 17 is a slot hole.

太陽光発電装置１１は、図に示すように、複数の支持台１２と、この支持台１２のそれぞれに下端を固定した複数の支柱１３と、これら支柱１３により地表に向かって傾斜を持たせて固定された枠体１４と、該枠体１４に取付けられた太陽電池パネル１５と、を備えている。支持台１２は、矩形状のコンクリートブロックで形成され、所定の重量を有している。支柱１３は、断面がＣ字状あるいはＨ字状の曲げ剛性を強めた鋼材が用いられ、支柱１３の下端は支持台１２に埋設固定されたアンカーボルト等により固定される。   As shown in the figure, the solar power generation device 11 has a plurality of support bases 12, a plurality of support pillars 13 each having a lower end fixed to each of the support support 12, and the support pillars 12 being inclined toward the ground surface. A fixed frame body 14 and a solar cell panel 15 attached to the frame body 14 are provided. The support base 12 is formed of a rectangular concrete block and has a predetermined weight. The strut 13 is made of a steel material having a C-shaped or H-shaped cross section with increased bending rigidity, and the lower end of the strut 13 is fixed by an anchor bolt or the like embedded in and fixed to the support base 12.

支持台１２に固定される支柱１３は、その長さが太陽光発電装置１１の前部側を短く、後部側で長くされていて、支柱１３の上端で矩形状の枠体１４を支えた際に、枠体１４を前部側が下方に、後部側が上方となって、地表に対して所定の傾斜角θ（５°〜４５°）を有するように取付け固定される。なお、地表に対する傾斜角θが小さいと太陽光との受光面積を大きくとることができず、大きいと倒れやすい。結果としては、傾斜角θは、２０°前後になるようにするのが好ましい。   The column 13 fixed to the support 12 has a length that is shorter on the front side of the photovoltaic power generation device 11 and longer on the rear side, and when the rectangular frame 14 is supported by the upper end of the column 13. The frame body 14 is attached and fixed so as to have a predetermined inclination angle θ (5 ° to 45 °) with respect to the ground surface with the front side facing downward and the rear side facing upward. In addition, if the inclination | tilt angle (theta) with respect to the ground surface is small, the light-receiving area with sunlight cannot be taken large, and if it is large, it will fall easily. As a result, the inclination angle θ is preferably about 20 °.

枠体１４は、表面側に太陽電池パネル１５が配列して取付けられるように、矩形状に形成される。枠体１４は、支柱１３に用いたのと同様なＣ型あるいはＨ型の鋼材を組み合わせて形成され、例えば、１つの矩形状の枠体として、所定の寸法で、中間フレームで適宜に補強して所望の強度を有するように形成される。   The frame 14 is formed in a rectangular shape so that the solar cell panels 15 are arranged and attached on the front surface side. The frame body 14 is formed by combining C-type or H-type steel materials similar to those used for the support column 13. For example, the frame body 14 has a predetermined size and is appropriately reinforced with an intermediate frame as a rectangular frame body. And having a desired strength.

枠体１４の表面側には、太陽電池パネル１５が貼り付け固定される。太陽電池パネル１５は、複数のパネル素子を並べて、所定の受光面積となるようにされている。また、太陽電池パネル１５は、上下２段に配列して、中間部分に太陽電池パネル１５がない水平方向に延びる領域を形成する。この領域には、後述するようにスロット孔１７を設け、背面からの風が抜けるように風抜け用のスロット孔とするとことができる。なお、スロット孔１７は、あまり大きくすると、太陽電池パネルの設置面積効率が悪くなり、小さ過ぎると風抜けの効果が少なく、スロット幅は２０ｃｍ前後とするのが好ましい。   A solar cell panel 15 is attached and fixed to the surface side of the frame body 14. The solar cell panel 15 has a plurality of panel elements arranged so as to have a predetermined light receiving area. Moreover, the solar cell panel 15 is arranged in two upper and lower stages, and forms a region extending in the horizontal direction without the solar cell panel 15 in the middle portion. In this region, a slot hole 17 can be provided as will be described later, and it can be used as a slot hole for removing air from the back surface. If the slot hole 17 is too large, the installation area efficiency of the solar cell panel is deteriorated. If the slot hole 17 is too small, the effect of wind draft is small, and the slot width is preferably about 20 cm.

枠体１４の裏面側には、風圧反力板１６が配設される。風圧反力板１６は、例えば、軽量で安価なアルミニウム等の金属板で形成され、その上端側を枠体１４の上下方向の途中位置に固定され、下端側を支柱１３または支持台１２に固定される。この風圧反力板１６は、太陽電池パネルが取付けられた枠体１４を、背面から支えるように、枠体１４の傾斜方向とは反対の方向に傾斜した状態となるように取付けられる。   A wind pressure reaction plate 16 is disposed on the back side of the frame body 14. The wind pressure reaction force plate 16 is formed of, for example, a light and inexpensive metal plate such as aluminum, and the upper end side thereof is fixed at a midway position in the vertical direction of the frame body 14 and the lower end side thereof is fixed to the support column 13 or the support base 12. Is done. The wind pressure reaction force plate 16 is attached so as to be inclined in a direction opposite to the inclination direction of the frame body 14 so as to support the frame body 14 to which the solar cell panel is attached from the back side.

図３は、上述した太陽光発電装置の背面からの風に対する風圧の状態を示すものである。図に示すように、太陽光発電装置の背面からの風は、傾斜して配設された太陽電池パネル１５および枠体１４の上半部と、傾斜して配設された風圧反力板１６に当たる。太陽電池パネル１５および枠体１４に当たる風により生じる風圧は、枠体１４を上方の矢印方向に押し倒す、あるいは、飛ばそうとするように作用する。   FIG. 3 shows the state of the wind pressure with respect to the wind from the back surface of the solar power generation apparatus described above. As shown in the figure, the wind from the rear surface of the photovoltaic power generation apparatus is inclined to the upper half of the solar cell panel 15 and the frame body 14 and the wind pressure reaction force plate 16 that is inclined. It hits. The wind pressure generated by the wind hitting the solar cell panel 15 and the frame body 14 acts to push down the frame body 14 in the upward arrow direction or to fly away.

一方、風圧反力板１６に当たる風は、これにより生じる風圧で、風圧反力板１６を下方に倒そうとするように作用する。そして、風圧反力板１６の上端が、枠体１４を支えるように連結されていることから、風圧反力板１６に作用する下方への力は、枠体１４を下方に向けて押さえ付けるように作用する。この結果、枠体１４の上方側に当たって生じる上方に作用する力を、風圧反力板１６により打ち消し、低減させることができる。   On the other hand, the wind that strikes the wind pressure reaction force plate 16 acts to cause the wind pressure reaction force plate 16 to fall down with the wind pressure generated by the wind pressure reaction force plate 16. And since the upper end of the wind-pressure reaction force board 16 is connected so that the frame body 14 may be supported, the downward force which acts on the wind-pressure reaction force board 16 will hold down the frame body 14 downward. Act on. As a result, the force acting on the upper side of the frame body 14 acting on the upper side can be canceled and reduced by the wind pressure reaction force plate 16.

また、風圧反力板１６の上端が固定され枠体に、水平方向にスロット孔１７を設けるようにすることが好ましい。このスロット孔１７を設けることにより、太陽光発電装置の背面当たる風を通り抜かせることができる。これにより、太陽光発電装置の背面に当たる全体の風圧を低減するようにし、上記の風圧反力板に加えて、さらに、枠体１４に作用する力を低減することができる。   Moreover, it is preferable that the upper end of the wind pressure reaction force plate 16 is fixed and the frame body is provided with the slot holes 17 in the horizontal direction. By providing this slot hole 17, it is possible to pass through the wind that hits the back surface of the photovoltaic power generation apparatus. Thereby, the whole wind pressure which hits the back surface of a solar power generation device can be reduced, and in addition to the above wind pressure reaction force plate, the force acting on the frame body 14 can be further reduced.

図１，２では、４個の支持台１２と、この支持台のそれぞれに支柱１３を固定した独立型のコンクリートブロックの例で説明したが、図４（Ａ）に示すように、前後の２つの支持台を１つにした複合型のコンクリートブロックからなる長い支持台１２’で形成することができる。
また、図４（Ｂ）に示す太陽光発電装置１１’のように、図１に示す太陽光発電装置の横幅をのばした形態とするようにしてもよい。この場合、横に長い枠体１４’、太陽電池パネル１５’で形成される。なお、風圧反力板１６’も横に長いもので形成してもよいが、図１の幅の短いものを複数枚取付けるようにしてもよい。 In FIG. 1 and FIG. 2, the example of the four support bases 12 and the independent concrete block in which the support pillars 13 are fixed to each of the support bases has been described. However, as shown in FIG. It can be formed of a long support base 12 'made of a composite concrete block with one support base.
Moreover, you may make it set it as the form which extended the width | variety of the solar power generation device shown in FIG. 1 like solar power generation device 11 'shown in FIG.4 (B). In this case, it is formed by a horizontally long frame 14 'and a solar cell panel 15'. Although the wind pressure reaction force plate 16 'may be formed to be long in the side, a plurality of the plates having a short width in FIG. 1 may be attached.

上述したように、傾斜して設置した太陽光発電装置の背面側に、風圧反力板を設けることにより、背面から受ける風により太陽光発電装置が倒れたり飛ばされるのを低減することができ、この結果、支持台の重量を軽くすることができる。例えば、図５，６の従来構造の太陽光発電装置では、独立型の１個の支持台の重量が８１６ｋｇのものを必要とする場合、本発明では、４５６ｋｇと半分近くまで軽量化することができた。このため、支持台をビルの屋上に吊り上げるクレーンも小形のものを用いることができ、支持台の重量軽減によることと併せて、コスト低減を図ることができる。また、支持台の重量軽減により、建物への負荷を軽減するとともに、設置作業の作業性を向上させることができる。   As described above, by providing a wind pressure reaction force plate on the back side of the photovoltaic power generation apparatus installed at an inclination, it is possible to reduce the photovoltaic power generation apparatus from falling or being blown by the wind received from the rear surface. As a result, the weight of the support base can be reduced. For example, in the conventional photovoltaic power generation apparatus of FIGS. 5 and 6, when the weight of one stand-alone support base is 816 kg, the present invention can reduce the weight to 456 kg, which is almost half. did it. For this reason, the crane which lifts a support stand on the roof of a building can also use a small thing, and it can aim at cost reduction together with the weight reduction of a support stand. Moreover, by reducing the weight of the support base, it is possible to reduce the load on the building and improve the workability of the installation work.
