Description

本発明は、複数の太陽電池モジュールを行列方向に並べて支持する太陽電池モジュール支持構造、その支持構造の施工方法、及びその支持構造を用いた太陽光発電システムに関する。   The present invention relates to a solar cell module support structure that supports a plurality of solar cell modules arranged in a matrix direction, a construction method of the support structure, and a photovoltaic power generation system using the support structure.

この種の太陽光発電システムとしては、例えば複数の桟を平行に並べて固定した架台を構成し、この架台の各桟の間に複数の太陽電池モジュールを架け渡して、各太陽電池モジュールを支持したものがある。   As this type of solar power generation system, for example, a base in which a plurality of crosspieces are arranged and fixed in parallel is configured, and a plurality of solar cell modules are bridged between the crosspieces of the base and each solar cell module is supported. There is something.

そのような架台は、架台そのものの強度が確保されるように桟の構造や材質等を決定している。また、太陽電池モジュールについても、太陽電池モジュールそのものの強度を確保したり、太陽電池パネルを保護するべく、太陽電池パネルを枠部材で縁取った構造が採用されている。   Such a frame determines the structure and material of the crosspiece so that the strength of the frame itself is ensured. Moreover, also about the solar cell module, the structure which bordered the solar cell panel with the frame member is employ | adopted in order to ensure the intensity | strength of a solar cell module itself or to protect a solar cell panel.

ところが、太陽電池モジュールを架台に搭載した場合は、太陽電池モジュールの枠と架台の桟などの類似した部材が重なり、太陽光発電システム全体の部品点数が無駄に多くなった。   However, when the solar cell module is mounted on the gantry, similar members such as the frame of the solar cell module and the frame of the gantry overlap, and the number of parts of the entire photovoltaic power generation system increases.

一方、太陽電池モジュールの枠部材を簡単な金具等で下地に直接固定する構造では、架台を必要としない。例えば、特許文献1では、太陽電池モジュールを2本の垂木上に載せて、太陽電池モジュールの枠部材の4箇所をそれぞれの据付部材で2本の垂木に固定している。また、小型の太陽電池モジュールを1本の垂木上に載せる場合は、小型の太陽電池モジュールの枠部材の2箇所をそれぞれの据付部材で1本の垂木に固定し、また小型の太陽電池モジュールの枠部材を連結金具を介して隣りの他の太陽電池モジュールの枠部材に連結して、小型の太陽電池モジュールの支持強度を高めている。   On the other hand, in a structure in which the frame member of the solar cell module is directly fixed to the base with a simple metal fitting or the like, no frame is required. For example, in Patent Document 1, a solar cell module is mounted on two rafters, and four locations of the frame member of the solar cell module are fixed to the two rafters by respective installation members. Moreover, when mounting a small solar cell module on one rafter, two places of the frame member of a small solar cell module are fixed to one rafter with each installation member, and also the small solar cell module The frame member is connected to the frame member of another adjacent solar cell module via a connecting metal fitting to increase the support strength of the small solar cell module.

しかしながら、特許文献1のような固定構造は、複数の太陽電池モジュールを一列に並べて固定するのに適していても、複数の太陽電池モジュールを行列方向に並べて固定するのには適していない。例えば、各列間のスペースを十分に広くしなければ、据付部材や連結金具の取付け作業を行うことができず、太陽光発電に寄与しない無駄なスペースの拡大を避けることができない。   However, although the fixing structure as in Patent Document 1 is suitable for arranging and fixing a plurality of solar cell modules in a row, it is not suitable for arranging and fixing a plurality of solar cell modules in a matrix direction. For example, if the space between the rows is not sufficiently wide, the installation work of the installation member and the connecting bracket cannot be performed, and the useless expansion of the space that does not contribute to solar power generation cannot be avoided.

特許2009−243062号公報Japanese Patent No. 2009-243062

このように太陽電池モジュールを架台に搭載した場合は、太陽電池モジュールの枠と架台の桟などの類似した部材が重なり、太陽光発電システム全体の部品点数が無駄に多くなった。 When the solar cell module is mounted on the gantry in this way, similar members such as a frame of the solar cell module and a frame of the gantry overlap, and the number of parts of the entire photovoltaic power generation system increases.

また、特許文献1の固定構造では、複数の太陽電池モジュールを一列に並べて固定するのに適していても、複数の太陽電池モジュールを行列方向に並べて固定するのには適しておらず、太陽光発電に寄与しない無駄なスペースの拡大を避けることができなかった。   In addition, the fixing structure of Patent Document 1 is not suitable for arranging and fixing a plurality of solar cell modules in a matrix direction even though it is suitable for arranging and fixing a plurality of solar cell modules in a row. Expansion of useless space that does not contribute to power generation could not be avoided.

そこで、本発明は、上記従来の問題点に鑑みてなされたものであり、複数の太陽電池モジュールを行列方向に並べて固定するのに適していて、部品点数を抑えることが可能な太陽電池モジュール支持構造、その支持構造の施工方法、及びその支持構造を用いた太陽光発電システムを提供することを目的とする。   Accordingly, the present invention has been made in view of the above-described conventional problems, and is suitable for fixing a plurality of solar cell modules side by side in a matrix direction and capable of suppressing the number of components. It is an object of the present invention to provide a structure, a construction method for the support structure, and a photovoltaic power generation system using the support structure.

上記課題を解決するために、本発明の太陽電池モジュール支持構造は、複数の太陽電池モジュールを行列方向に並べて支持する太陽電池モジュール支持構造であって、相反するそれぞれの外側方向に向く2つの係合部が形成された行列連結具と、相反するそれぞれの外側方向に向く2つの係合部が形成された行間連結具と、前記行間連結具を支持して前記太陽電池モジュール支持構造の土台に固定される固定具とを備え、前記行列連結具が2行2列における4枚の太陽電池モジュールの行間に配置され、前記行間連結具が前記固定具を用いて土台に固定され、かつ前記行列連結具が土台に固定されていない。 In order to solve the above-described problems, the solar cell module support structure of the present invention is a solar cell module support structure that supports a plurality of solar cell modules arranged in a matrix direction and has two relations facing in opposite opposite directions. A matrix connector in which joint portions are formed, an inter-row connector in which two oppositely facing engaging portions are formed, and a support for the inter-row connector to support the solar cell module support structure. And the matrix connector is arranged between four solar cell modules in two rows and two columns , the inter-row connector is fixed to a base using the fixture, and the matrix The connector is not fixed to the foundation.

このように行列連結具により2行2列における4枚の太陽電池モジュールを連結すれば、行列方向に並べられた各太陽電池モジュールを一体的に支持することができ、従来の架台の桟等を必要とせず、部品点数の無駄な増加を抑えることができ、太陽光発電に寄与しない無駄なスペースを最小限に抑えることができる。   In this way, by connecting four solar cell modules in 2 rows and 2 columns with a matrix connector, it is possible to integrally support the solar cell modules arranged in the matrix direction, such as a conventional frame for a frame, etc. It is not necessary, and a wasteful increase in the number of parts can be suppressed, and a wasteful space that does not contribute to photovoltaic power generation can be minimized.

また、行間連結具を行列連結具と併用しているので、行列方向に並べられた各太陽電池モジュールをより強固に一体的に支持することができる。 Moreover, since the row connection tool is used together with the matrix connection tool, the solar cell modules arranged in the matrix direction can be supported more firmly and integrally.

また、固定具により、行列方向に並べられた各太陽電池モジュールを土台上に設置することができる Moreover, the solar cell modules arranged in the matrix direction can be installed on the base by the fixture .

また、本発明の太陽電池モジュール支持構造においては、両側の他の太陽電池モジュールの間に配置される太陽電池モジュールについては、2つの前記行間連結具が用いられて、太陽電池モジュールの相互に対向する各枠部材の中央付近が前記太陽電池モジュール支持構造の土台に固定支持されている。   Moreover, in the solar cell module support structure of this invention, about the solar cell module arrange | positioned between the other solar cell modules of both sides, the two said row | line | column connection tools are used, and a solar cell module mutually opposes. The vicinity of the center of each frame member is fixedly supported on the base of the solar cell module support structure.

両側の他の太陽電池モジュールの間に配置される太陽電池モジュールは、その両端を両側の他の太陽電池モジュールにより支持されるので、太陽電池モジュールの相互に対向する各枠部材の中央付近が固定支持されるだけでも、安定的に支持される。   Since the solar cell modules arranged between the other solar cell modules on both sides are supported by the other solar cell modules on both sides, the vicinity of the center of each frame member facing each other of the solar cell modules is fixed. Even if it is supported, it is supported stably.

また、太陽電池モジュールの相互に対向する各枠部材の中央付近を支持すると、太陽電池モジュールのたわみ等の変形を効果的に抑えることができる。   Moreover, if the vicinity of the center of each frame member facing each other of the solar cell module is supported, deformation such as deflection of the solar cell module can be effectively suppressed.

更に、本発明の太陽電池モジュール支持構造においては、前記固定具は、前記行間連結具を前記列の方向に移動可能に支持している。 Furthermore, in the solar cell module support structure of this invention, the said fixing tool is supporting the said row | line | column connection tool so that a movement to the said column is possible .

これにより、行間連結具を列に並ぶ2枚の太陽電池モジュールの枠部材の間に配置することが容易になる
また、本発明の太陽電池モジュール支持構造においては、前記行列連結具は、該行列連結具の係合部に係合された2枚の太陽電池モジュールの枠部材にネジ止めされている。
This makes it easy to arrange the row-to-row connectors between the frame members of the two solar cell modules arranged in a column. In the solar cell module support structure of the present invention, the matrix connector has the matrix Screwed to the frame member of the two solar cell modules engaged with the engaging portion of the connector.

この場合は、ネジにより行列連結具を2枚の太陽電池モジュールの枠部材に電気的に導通させることができ、各太陽電池モジュールの接地配線が簡単になる。   In this case, the matrix connector can be electrically connected to the frame members of the two solar cell modules by screws, and the ground wiring of each solar cell module is simplified.

更に、本発明の太陽電池モジュール支持構造においては、前記行列連結具は、該行列連結具の係合部に係合した太陽電池モジュールの枠部材に食い込む突起を有する。あるいは、前記行間連結具は、該行間連結具の係合部に係合した太陽電池モジュールの枠部材に食い込む突起を有する。   Furthermore, in the solar cell module support structure of this invention, the said matrix connector has a protrusion which bites into the frame member of the solar cell module engaged with the engaging part of this matrix connector. Alternatively, the inter-row connector has a protrusion that bites into the frame member of the solar cell module engaged with the engaging portion of the inter-row connector.

このような突起により、行列連結具もしくは行間連結金具を太陽電池モジュールの枠部材に電気的に導通させることが可能になり、行列方向に並べられた各太陽電池モジュール全てを導通させることができ、各太陽電池モジュールの接地配線が容易になる。   With such protrusions, it becomes possible to electrically connect the matrix connector or the inter-row connection fitting to the frame member of the solar cell module, and it is possible to conduct all the solar cell modules arranged in the matrix direction, The ground wiring of each solar cell module becomes easy.

また、本発明の太陽電池モジュール支持構造においては、前記太陽電池モジュールの枠部材には溝が設けられ、前記行列連結具又は前記行間連結具には前記溝に嵌る突起が設けられている。In the solar cell module support structure of the present invention, the frame member of the solar cell module is provided with a groove, and the matrix connector or the inter-row connector is provided with a protrusion that fits into the groove.

また、本発明の施工方法は、上記本発明の太陽電池モジュール支持構造の施工方法であって、最初に設置される1枚目の太陽電池モジュールについては、少なくとも3組の前記行間連結具及び前記固定具を用いて、太陽電池モジュールの枠部材の少なくとも3箇所を固定支持し、2枚目以降の太陽電池モジュールについては、少なくとも2組の前記行間連結具及び前記固定具を用いて、太陽電池モジュールの枠部材の少なくとも2箇所を固定支持し、太陽電池モジュールの枠部材を前記行列連結具を介して既に設置された他の太陽電池モジュールの枠部材と連結している。   Moreover, the construction method of the present invention is a construction method of the solar cell module support structure of the present invention, and for the first solar cell module to be installed first, at least three sets of the inter-row connectors and the above A fixing device is used to fix and support at least three places of the frame member of the solar cell module, and for the second and subsequent solar cell modules, at least two sets of the inter-row connector and the fixing device are used. At least two places of the frame members of the module are fixedly supported, and the frame members of the solar cell module are connected to the frame members of other solar cell modules already installed through the matrix connector.

このように最初に設置される1枚目の太陽電池モジュールの枠部材の少なくとも3箇所を固定支持すれば、1枚目の太陽電池モジュールを安定的に支持することができ、2枚目の太陽電池モジュールを行列連結具を介して1枚目の太陽電池モジュールに連結する作業が容易となり、行列連結具により2枚目の太陽電池モジュールも安定的に支持することができ、3枚目以降の太陽電池モジュールについても同様の作用効果が得られる。   Thus, if at least three places of the frame member of the first solar cell module installed first are fixedly supported, the first solar cell module can be stably supported, and the second solar cell module can be supported. The battery module can be easily connected to the first solar cell module via the matrix connector, and the second solar cell module can be stably supported by the matrix connector. Similar effects can be obtained with solar cell modules.

また、2枚目以降の太陽電池モジュールについては、行間連結具及び固定具を2組だけ用いて、部品点数の節減を図ることができる。   In addition, for the second and subsequent solar cell modules, the number of parts can be reduced by using only two sets of inter-row connection tools and fixtures.

更に、本発明の施工方法においては、両側の他の太陽電池モジュールの間に配置される太陽電池モジュールについては、2組の前記行間連結具及び前記固定具を用いて、太陽電池モジュールの相互に対向する各枠部材の中央付近を固定支持している。   Furthermore, in the construction method of the present invention, with respect to the solar cell module disposed between the other solar cell modules on both sides, the solar cell modules are connected to each other using two sets of the inter-row connector and the fixture. The vicinity of the center of each opposing frame member is fixedly supported.

このように太陽電池モジュールの相互に対向する各枠部材の中央付近を固定支持すれば、太陽電池モジュールのたわみ等の変形を効果的に抑えることができる。 Thus, if the vicinity of the center of each frame member facing each other of the solar cell module is fixedly supported, deformation such as bending of the solar cell module can be effectively suppressed.

また、本発明の太陽光発電システムは、上記本発明の太陽電池モジュール支持構造を用いている。 Moreover, the solar power generation system of the present invention uses the solar cell module support structure of the present invention.

このような太陽光発電システムにおいても、上記本発明の太陽電池モジュール支持構造と同様の作用効果が得られる。   Also in such a solar power generation system, the same effect as the solar cell module support structure of the present invention can be obtained.

本発明によれば、行列連結具により2行2列における4枚の太陽電池モジュールを連結しているので、行列方向に並べられた各太陽電池モジュールを一体的に支持することができ、従来の架台の桟等を必要とせず、部品点数の無駄な増加を抑えることができる。   According to the present invention, since the four solar cell modules in 2 rows and 2 columns are connected by the matrix connector, the solar cell modules arranged in the matrix direction can be integrally supported, There is no need for a frame or the like for the frame, and a wasteful increase in the number of parts can be suppressed.

また、行間連結具を行列連結具と併用しているので、行列方向に並べられた各太陽電池モジュールをより強固に一体的に支持することができる。 Moreover, since the row connection tool is used together with the matrix connection tool, the solar cell modules arranged in the matrix direction can be supported more firmly and integrally.

更に、固定具により、行列方向に並べられた各太陽電池モジュールを土台上に設置することができる。 Furthermore, the solar cell modules arranged in the matrix direction can be installed on the base by the fixture.

図7は、固定金具6を示す斜視図である。また、図8(a)、(b)、(c)は、固定金具6を示す側面図、平面図、及び正面図である。   FIG. 7 is a perspective view showing the fixing bracket 6. FIGS. 8A, 8 </ b> B, and 8 </ b> C are a side view, a plan view, and a front view showing the fixing bracket 6.

図7及び図8に示すように固定金具6は、長矩形の主板6aと、主板6aの両辺で上方に折り曲げられた各側壁6bと、各側壁6bの上辺で内側に折り曲げられた各天板6cと、各天板6cの内側辺で下方に折り曲げられた各ガイド壁6dとを有している。各ガイド壁6d間に隙間が形成され、この隙間がスリット6eとなっている。また、各側板6bの一端部近傍には、それぞれのストッパー6fが形成されている。   As shown in FIGS. 7 and 8, the fixture 6 includes a long rectangular main plate 6a, side walls 6b bent upward on both sides of the main plate 6a, and top plates bent inward on the upper sides of the side walls 6b. 6c and each guide wall 6d bent downward at the inner side of each top plate 6c. A gap is formed between each guide wall 6d, and this gap is a slit 6e. Each stopper 6f is formed near one end of each side plate 6b.

図9は、行間連結金具5を固定金具6に取付けるための取付け金具11を示す斜視図である。図9に示すように取付け金具11は、その主板11aにネジ孔11bを形成し、主板11aの両辺を上側に折り曲げてT字型の各支持片11cを形成し、また主板11aの両側を3回折り曲げて(下側、外側、上側に順次折り曲げて)、各摺動部11dを形成したものである。   FIG. 9 is a perspective view showing an attachment fitting 11 for attaching the inter-row connection fitting 5 to the fixing fitting 6. As shown in FIG. 9, the mounting bracket 11 is formed with a screw hole 11b in the main plate 11a, bent upward on both sides of the main plate 11a to form T-shaped support pieces 11c, and three sides of the main plate 11a. Each sliding part 11d is formed by folding it in turn (sequentially bending downward, outward and upward).

このような行列連結金具4、行間連結金具5、固定金具6、及び取付け金具11のいずれも、例えば鋼板を打ち抜き、切断、折り曲げ加工して、メッキ処理を施したものである。また、行列連結金具4については、アルミの打ち抜き加工により形成したものであっても構わない。   All of the matrix connection fitting 4, the inter-row connection fitting 5, the fixing fitting 6, and the attachment fitting 11 are formed by, for example, punching, cutting, and bending a steel plate and performing plating. Further, the matrix connection fitting 4 may be formed by stamping aluminum.

ここで、先に述べたように固定金具6は、適宜の方法もしくは構造により屋根に固定される。このとき、固定金具6のスリット6eが図1の水流れ方向Cに沿うように、また固定金具6のストッパー6fが水流れ方向下側に位置するように、固定金具6の向きを設定する。そして、固定金具6に取付け金具11を取付け、更に行間連結金具5を固定金具6に固定する。 Here, as described above, the fixing bracket 6 is fixed to the roof by an appropriate method or structure. At this time, the orientation of the fixing bracket 6 is set so that the slit 6e of the fixing bracket 6 is along the water flow direction C in FIG. 1 and the stopper 6f of the fixing bracket 6 is positioned below the water flow direction. Then, the mounting bracket 11 is attached to the fixing bracket 6, and the inter-row connecting bracket 5 is fixed to the fixing bracket 6.

図10は、行間連結金具5、固定金具6、及び取付け金具11を示す分解斜視図である。また、図11は、行間連結金具5、固定金具6、及び取付け金具11の固定構造を示す断面図である。 FIG. 10 is an exploded perspective view showing the inter-row connection fitting 5, the fixing fitting 6, and the attachment fitting 11. FIG. 11 is a cross-sectional view showing a fixing structure of the inter-row connecting metal fitting 5, the fixing metal fitting 6, and the attachment metal fitting 11.

図10に示すように取付け金具11の各支持片11cを固定金具6のスリット6eに差し込んで、各支持片11cのT字型の頭部を各天板6cに引っ掛け、取付け金具11の各摺動部11dを固定金具6の両側の側壁6bとガイド壁6d間に挿入して、取付け金具11を固定金具6に取付ける。これにより、取付け金具11が固定金具6のスリット6eに沿って移動自在に支持される。また、固定金具6のストッパー6fにより取付け金具11の水流れ方向下側への脱落が防止される。   As shown in FIG. 10, each support piece 11c of the mounting bracket 11 is inserted into the slit 6e of the fixing bracket 6, and the T-shaped head of each support piece 11c is hooked on each top plate 6c. The moving part 11d is inserted between the side wall 6b on both sides of the fixing bracket 6 and the guide wall 6d, and the mounting bracket 11 is attached to the fixing bracket 6. Thereby, the mounting bracket 11 is supported so as to be movable along the slit 6e of the fixing bracket 6. Further, the stopper 6f of the fixing bracket 6 prevents the mounting bracket 11 from dropping downward in the water flow direction.

この後、図11に示すように固定金具6の各天板6c上に突出した取付け金具11の各支持片11cの頭部間に行間連結金具5の底板5bを挟み込んで、行間連結金具5の底板5bを固定金具6の各天板6c上に載せ、行間連結金具5の底板5bの穿孔5gを取付け金具11の主板11aのネジ孔11bに重ね合わせ、ボルト12を行間連結金具5の穿孔5gを介して取付け金具11のネジ孔11bにねじ込んで、行間連結金具5を固定金具6に仮止めする。この仮止めの状態で行間連結金具5を列方向Bに移動させて位置決めし、この後にボルト12を締め付けて、行間連結金具5を固定金具6に固定する。   After that, as shown in FIG. 11, the bottom plate 5 b of the inter-row connecting bracket 5 is sandwiched between the heads of the support pieces 11 c of the mounting bracket 11 protruding on the top plates 6 c of the fixing bracket 6. The bottom plate 5 b is placed on each top plate 6 c of the fixing bracket 6, the perforation 5 g of the bottom plate 5 b of the row fitting 5 is overlapped with the screw hole 11 b of the main plate 11 a of the mounting bracket 11, and the bolt 12 is drilled 5 g of the row fitting 5. Then, the inter-row connection fitting 5 is temporarily fixed to the fixing fitting 6 by being screwed into the screw holes 11 b of the attachment fitting 11. In this temporarily fixed state, the row connecting bracket 5 is moved and positioned in the column direction B, and then the bolt 12 is tightened to fix the row connecting bracket 5 to the fixing bracket 6.

例えば、図1に示すような1行目(水流れ方向Cの最も下側の行)の各太陽電池モジュール2を直線状に配列するべく、最も下側の各行間連結金具5をそれぞれ列方向Bに適宜に移動させて、各行間連結金具5を行方向Aの直線に沿うように位置決めし、この後にボルト12を締め付けて、各行間連結金具5を固定金具6に固定する。   For example, in order to arrange the solar cell modules 2 in the first row (the lowermost row in the water flow direction C) as shown in FIG. The inter-row connection fittings 5 are appropriately moved to B to position the inter-row connection fittings 5 along the straight line in the row direction A, and then the bolts 12 are tightened to fix the inter-row connection fittings 5 to the fixing fittings 6.

こうして固定された行間連結金具5により列方向Bに並ぶ各太陽電池モジュール2の辺が連結接続される。 The sides of the solar cell modules 2 arranged in the column direction B are connected and connected by the inter-row connection fitting 5 thus fixed.

図11に示すように行間連結金具5は、列方向Bに並ぶ各太陽電池モジュール2の間に挟まれる。あるいは、1行目の各太陽電池モジュール2の一辺(水流れ方向下側の一辺)に接する。 As shown in FIG. 11, the inter-row connection fitting 5 is sandwiched between the solar cell modules 2 arranged in the column direction B. Or it contacts one side (one side below the water flow direction) of each solar cell module 2 in the first row.

行間連結金具5両側の各太陽電池モジュール2のうちの水流れ方向上側(及び1行目)にある太陽電池モジュール2については、その枠部材8が行間連結金具5の各搭載部5fに載せられる。そして、枠部材8が行間連結金具5の第1留め部5dの押え部5jの下側に押し込められて、第1留め部5dの押え部5jにより枠部材8の上面が押えられ、枠部材8が行間連結金具5の各搭載部5fと第1留め部5dの押え部5j間に挟みこまれて固定される。また、枠部材8の端面が行間連結金具5の立設板5aに当接される。すなわち、水流れ方向上側(及び1行目)にある太陽電池モジュール2の枠部材8が行間連結金具5の係合部5m(図5(a)、(b)、図6(b)を参照)に係合する。   For the solar cell module 2 on the upper side (and the first row) in the water flow direction among the solar cell modules 2 on both sides of the row connection fitting 5, the frame member 8 is placed on each mounting portion 5 f of the row connection fitting 5. . Then, the frame member 8 is pushed into the lower side of the pressing portion 5j of the first fastening portion 5d of the inter-row connection fitting 5, and the upper surface of the frame member 8 is pressed by the holding portion 5j of the first fastening portion 5d. Is sandwiched and fixed between each mounting portion 5f of the inter-row connection fitting 5 and the pressing portion 5j of the first fastening portion 5d. Further, the end surface of the frame member 8 is brought into contact with the standing plate 5 a of the inter-row connection fitting 5. That is, the frame member 8 of the solar cell module 2 on the upper side (and the first row) in the water flow direction is the engaging portion 5m (see FIGS. 5A, 5B, and 6B) of the inter-row connection fitting 5. ).

例えば、二点鎖線で示すように太陽電池モジュール2を傾斜させて、枠部材8を行間連結金具5の各搭載部5fに載せてスライドさせ、枠部材8の下側角を行間連結金具5の各搭載部5fと立設板5a間の空きスペースに移動させると共に、枠部材8を第1留め部5dの呼込み部5kから押え部5jへと挿入して押し込み、引き続いて太陽電池モジュール2を水平に降ろす。これにより、枠部材8が各搭載部5fと第1留め部5dの押え部5j間に挟みこまれて固定され、枠部材8の端面が立設板5aに当接する。   For example, as shown by a two-dot chain line, the solar cell module 2 is tilted, the frame member 8 is slid on each mounting portion 5f of the inter-row connection fitting 5, and the lower corner of the frame member 8 is placed on the inter-connection fitting 5 While moving to the empty space between each mounting part 5f and the standing board 5a, the frame member 8 is inserted and pushed into the holding part 5j from the calling part 5k of the first fastening part 5d, and then the solar cell module 2 is horizontally placed. Take it down. As a result, the frame member 8 is sandwiched and fixed between the mounting portions 5f and the pressing portions 5j of the first fastening portions 5d, and the end surface of the frame member 8 comes into contact with the standing plate 5a.

第1留め部5dの先端側に斜め上方に折り曲げられた呼込み部5k形成していることから、傾斜した太陽電池モジュール2の枠部材8を第1留め部5dの呼込み部5kの下側に容易に入れることができ、引き続いて枠部材8を第1留め部5dの呼込み部6kから押え部5jへと容易に挿入して押し込むことができる。   Since the incoming portion 5k bent obliquely upward is formed on the distal end side of the first fastening portion 5d, the frame member 8 of the inclined solar cell module 2 can be easily placed below the incoming portion 5k of the first fastening portion 5d. Subsequently, the frame member 8 can be easily inserted and pushed into the holding portion 5j from the calling portion 6k of the first fastening portion 5d.

また、行間連結金具5の各搭載部5fと立設板5a間を離間させていることから、第1留め部5dの下方が空き、枠部材8を行間連結金具5の各搭載部5fに載せてスライドさ
せると、傾斜した太陽電池モジュール2の枠部材8の下側角が各搭載部5fと立設板5a間に落ち込んで、枠部材8の上面を各第1留め部5dの押え部5jまで容易に押し込むことができる。
In addition, since each mounting portion 5f of the inter-row connecting bracket 5 and the upright plate 5a are separated from each other, the lower portion of the first fastening portion 5d is empty, and the frame member 8 is mounted on each mounting portion 5f of the inter-row connecting bracket 5. The lower corners of the frame member 8 of the inclined solar cell module 2 fall between the mounting portions 5f and the standing plates 5a, and the upper surface of the frame member 8 is pressed against the pressing portions 5j of the first fastening portions 5d. Can be pushed in easily.

尚、二点鎖線で示すように太陽電池モジュール2を傾斜させず、太陽電池モジュール2の枠部材8を行間連結金具5の各搭載部5fに載せて水平に支持したまま、枠部材8を行間連結金具5の第1留め部5dの押え部5jの下側に押し込んでも構わない。   The solar cell module 2 is not inclined as shown by the two-dot chain line, and the frame member 8 is placed between the rows while the frame member 8 of the solar cell module 2 is placed horizontally on the mounting portions 5f of the inter-row connection fitting 5 and supported horizontally. You may push into the press part 5j of the 1st fastening part 5d of the connection metal fitting 5 below.

また、図11に示すように行間連結金具5両側の各太陽電池モジュール2のうちの水流れ方向下側にある太陽電池モジュール2については、その枠部材8が行間連結金具5の台座部5hに載せられる。そして、枠部材8が行間連結金具5の第2留め部5eの下側に押し込められて、第2留め部5eにより枠部材8の上面が押えられ、枠部材8が行間連結金具5の台座部5hと第2留め部5e間に挟みこまれて固定される。また、枠部材8の端面が行間連結金具5の立設板5aに当接される。すなわち、水流れ方向下側にある太陽電池モジュール2の枠部材8が行間連結金具5の係合部5n(図5(a)、(b)、図6(b)を参照)に係合する。   Further, as shown in FIG. 11, the frame member 8 of the solar cell module 2 on the lower side in the water flow direction among the solar cell modules 2 on both sides of the inter-row connection fitting 5 is connected to the base portion 5 h of the inter-row connection fitting 5. Can be placed. Then, the frame member 8 is pushed into the lower side of the second fastening part 5e of the inter-row connecting metal 5, the upper surface of the frame member 8 is pressed by the second fastening part 5e, and the frame member 8 is a pedestal part of the inter-line connecting metal 5 It is sandwiched and fixed between 5h and the second fastening part 5e. Further, the end surface of the frame member 8 is brought into contact with the standing plate 5 a of the inter-row connection fitting 5. That is, the frame member 8 of the solar cell module 2 located on the lower side in the water flow direction is engaged with the engaging portion 5n (see FIGS. 5A, 5B, and 6B) of the inter-row connection fitting 5. .

例えば、二点鎖線で示すように太陽電池モジュール2の枠部材8を行間連結金具5の台座部5hに載せてから、行間連結金具5を太陽電池モジュール2の枠部材8に接近するように水平方向に移動させて、枠部材8を行間連結金具5の台座部5hと第2留め部5e間に挿入して押し込む。これにより、枠部材8が台座部5hと第2留め部5e間に挟みこまれて固定され、枠部材8の端面が立設板5aに当接する。   For example, as shown by a two-dot chain line, the frame member 8 of the solar cell module 2 is placed on the pedestal portion 5 h of the inter-row connection fitting 5, and then the inter-row connection fitting 5 is placed horizontally so as to approach the frame member 8 of the solar cell module 2. The frame member 8 is inserted between the pedestal part 5h and the second fastening part 5e of the inter-row connection fitting 5 and pushed in. As a result, the frame member 8 is sandwiched and fixed between the pedestal portion 5h and the second fastening portion 5e, and the end surface of the frame member 8 comes into contact with the standing plate 5a.

従って、水流れ方向上側にある太陽電池モジュール2の枠部材8が行間連結金具5の一方の係合部5mに係合し、水流れ方向下側にある太陽電池モジュール2の枠部材8が行間連結金具5の他方の係合部5nに係合し、列方向Bに並ぶ各太陽電池モジュール2の枠部材8が行間連結金具5を介して連結接続される。   Accordingly, the frame member 8 of the solar cell module 2 on the upper side in the water flow direction is engaged with one of the engaging portions 5m of the inter-row connection fitting 5, and the frame member 8 of the solar cell module 2 on the lower side in the water flow direction is between the rows. The frame member 8 of each solar cell module 2 that is engaged with the other engaging portion 5 n of the connecting metal 5 and arranged in the column direction B is connected and connected via the inter-row connecting metal 5.

次に、行列連結金具4は、各太陽電池モジュール2の角近傍を連結接続するために用いられる。図12は、行列連結金具4による太陽電池モジュール2の枠部材8の連結構造を示す斜視図である。また、図13は、その連結構造を示す断面図である。   Next, the matrix connection fitting 4 is used for connecting and connecting the vicinity of the corners of each solar cell module 2. FIG. 12 is a perspective view showing a connection structure of the frame member 8 of the solar cell module 2 by the matrix connection fitting 4. Moreover, FIG. 13 is sectional drawing which shows the connection structure.

図12、図13に示すように行列連結金具4両側の各太陽電池モジュール2のうちの水流れ方向下側(及び1行目)にある太陽電池モジュール2については、その枠部材8が、行列連結金具4の一方の係合凹部4d(図3、図4(b)を参照)に嵌合されて、行列連結金具4の底板4aと天板4b間に挟みこまれる。また、行方向Aに並ぶ2枚の太陽電池モジュール2の枠部材8の端部が、行列連結金具4の一方の係合凹部4dに共に嵌合される。そして、ネジ13が2本ずつ、行列連結金具4の各穿孔4eを介して2枚の太陽電池モジュール2の枠部材8にそれぞれねじ込まれて、行列連結金具4が2枚の太陽電池モジュール2の枠部材8に固定される。すなわち、水流れ方向下側(及び1行目)にあって行方向Aに並ぶ2枚の太陽電池モジュール2の枠部材8が行列連結金具4の一方の係合凹部4dに係合してネジ止めされる。   As shown in FIGS. 12 and 13, for the solar cell module 2 on the lower side (and the first row) in the water flow direction among the solar cell modules 2 on both sides of the matrix connection fitting 4, the frame member 8 is a matrix. It is fitted into one engaging recess 4d (see FIGS. 3 and 4B) of the connecting fitting 4 and is sandwiched between the bottom plate 4a and the top plate 4b of the matrix connecting fitting 4. Further, the end portions of the frame members 8 of the two solar cell modules 2 arranged in the row direction A are fitted together in one engagement recess 4 d of the matrix connection fitting 4. Then, two screws 13 are screwed into the frame members 8 of the two solar cell modules 2 through the perforations 4e of the matrix connection fittings 4 respectively, so that the matrix connection fittings 4 are connected to the two solar cell modules 2. It is fixed to the frame member 8. That is, the frame members 8 of the two solar cell modules 2 that are on the lower side (and the first row) in the water flow direction and are aligned in the row direction A are engaged with one of the engagement recesses 4d of the matrix connection fitting 4 and screwed. Stopped.

また、行列連結金具4両側の各太陽電池モジュール2のうちの水流れ方向上側にある太陽電池モジュール2については、その枠部材8が、行列連結金具4の他方の係合凹部4dに嵌合されて、行列連結金具4の底板4aと天板4b間に挟みこまれる。また、行方向Aに並ぶ2枚の太陽電池モジュール2の枠部材8の端部が、行列連結金具4の他方の係合凹部4dに共に嵌合される。すなわち、水流れ方向上側にあって行方向Aに並ぶ2枚の太陽電池モジュール2の枠部材8が行列連結金具4の一方の係合凹部4dに係合する。   In addition, for the solar cell module 2 on the upper side in the water flow direction among the solar cell modules 2 on both sides of the matrix connection fitting 4, the frame member 8 is fitted in the other engagement recess 4 d of the matrix connection fitting 4. And sandwiched between the bottom plate 4a and the top plate 4b of the matrix connection fitting 4. Further, the end portions of the frame members 8 of the two solar cell modules 2 arranged in the row direction A are fitted together with the other engaging recess 4 d of the matrix connection fitting 4. That is, the frame members 8 of the two solar cell modules 2 that are on the upper side in the water flow direction and are aligned in the row direction A engage with one of the engagement recesses 4 d of the matrix connection fitting 4.

従って、水流れ方向下側(及び1行目)にあって行方向Aに並ぶ2枚の太陽電池モジュール2の枠部材8が行列連結金具4の一方の係合凹部4dに係合してネジ止めされ、水流れ方向上側にあって行方向Aに並ぶ2枚の太陽電池モジュール2の枠部材8が行列連結金具4の他方の係合凹部4dに係合し、2行2列に並ぶ4枚の太陽電池モジュール2が行列連結具4を介して連結接続される。   Accordingly, the frame members 8 of the two solar cell modules 2 that are on the lower side in the water flow direction (and the first row) and are aligned in the row direction A engage with one of the engagement recesses 4d of the matrix connection fitting 4 and screw. The frame members 8 of the two solar cell modules 2 that are stopped and arranged in the row direction A on the upper side of the water flow direction engage with the other engagement recesses 4d of the matrix connection fitting 4, and are arranged in 2 rows and 2 columns 4 The two solar cell modules 2 are connected and connected via the matrix connector 4.

The inter-row connection fittings 5 are temporarily fixed on the respective fixing fittings 6.

そして、水流れ方向Cの最も下側の各行間連結金具5をそれぞれ列方向Bに適宜に移動させて、これらの行間連結金具5を行方向Aの直線に沿うように位置決めし、それぞれのボルト12を締め付けて、これらの行間連結金具5を固定金具6に固定する。   And each row | line | column connection metal fitting 5 of the lowermost side of the water flow direction C is each moved to the column direction B suitably, these line connection metal fittings 5 are positioned along the straight line of the row direction A, and each bolt 12 is tightened to fix the inter-row connection fitting 5 to the fixing fitting 6.

次に、最初の1番目の太陽電池モジュール2を1行1列目の位置に配置する。そして、図14(a)に示すように太陽電池モジュール2の枠部材8を水流れ方向Cの最も下側の行間連結金具5の各搭載部5fと下側から2番目の行間連結金具5の台座部5hに載せる。このとき、下側から2番目の行間連結金具5を固定金具6上で列方向Bに移動させて、行間連結金具5の位置調節を行ってもよい。   Next, the first first solar cell module 2 is arranged at the position of the first row and the first column. And as shown to Fig.14 (a), the frame member 8 of the solar cell module 2 of each mounting part 5f of the lowermost row | line | column connection metal fitting 5 of the water flow direction C and the 2nd line | wire connection metal fitting 5 of the 2nd from the lower side. Place on pedestal 5h. At this time, the position of the inter-row connecting bracket 5 may be adjusted by moving the second inter-row connecting bracket 5 from the lower side in the column direction B on the fixing bracket 6.

更に、図14(b)に示すように太陽電池モジュール2の水流れ方向上側一辺を持ち上
げ、図14(c)に示すように太陽電池モジュール2の枠部材8をスライドさせて行間連結金具5の第1留め部5dの呼込み部5kから押え部5jへと挿入して押し込む。
Further, as shown in FIG. 14 (b), the upper side in the water flow direction of the solar cell module 2 is lifted, and the frame member 8 of the solar cell module 2 is slid as shown in FIG. It inserts and pushes in from the call-in part 5k of the 1st fastening part 5d to the press part 5j.

引き続いて、図14(d)に示すように太陽電池モジュール2の水流れ方向上側一辺を降ろして、太陽電池モジュール2の水流れ方向上側一辺を下側から2番目の行間連結金具5の台座部5hに載せる。このとき、太陽電池モジュール2の水流れ方向下側の枠部材8が行間連結金具5の係合部5m(図5(a)、(b)、図6(b)を参照)に係合する。   Subsequently, as shown in FIG. 14 (d), the upper side in the water flow direction of the solar cell module 2 is lowered, and the upper side in the water flow direction of the solar cell module 2 is placed on the pedestal portion of the second row connection fitting 5 from the lower side. Put on 5h. At this time, the frame member 8 on the lower side in the water flow direction of the solar cell module 2 engages with the engaging portion 5m (see FIGS. 5A, 5B, and 6B) of the inter-row coupling fitting 5. .

そして、下側から2番目の行間連結金具5を固定金具6上で水流れ方向Cに移動させて、太陽電池モジュール2の水流れ方向上側の枠部材8を行間連結金具5の台座部5hと第2留め部5e間に挿入して押し込む。これにより、太陽電池モジュール2の水流れ方向上側の枠部材8が行間連結金具5の係合部5n(図5(a)、(b)、図6(b)を参照)に係合する。更に、下側から2番目の行間連結金具5のボルト12を締め付けて、この行間連結金具5を固定する。   Then, the second row connection fitting 5 from the lower side is moved in the water flow direction C on the fixed fitting 6, and the frame member 8 on the upper side in the water flow direction of the solar cell module 2 is connected to the pedestal portion 5 h of the row connection fitting 5. Insert and push between the second fastening portions 5e. Thereby, the frame member 8 on the upper side in the water flow direction of the solar cell module 2 is engaged with the engaging portion 5n (see FIGS. 5A, 5B, and 6B) of the inter-row connection fitting 5. Further, the bolt 12 of the second inter-row connection fitting 5 from the lower side is tightened to fix the inter-row connection fitting 5.

先に述べたように1行1列目の太陽電池モジュール2については、相互に対向する行方向Aの2本の枠部材8と交差する3つ以上の箇所にそれぞれの固定金具6を固定配置していることから、これらの箇所でそれぞれの行間連結金具5に太陽電池モジュール2の枠部材8が係合する。このため、1行1列目の太陽電池モジュール2がぐらつくことなく安定的に支持される。   As described above, with respect to the solar cell module 2 in the first row and the first column, the respective fixing fittings 6 are fixedly arranged at three or more points intersecting the two frame members 8 in the row direction A facing each other. Therefore, the frame member 8 of the solar cell module 2 is engaged with each inter-row connection fitting 5 at these locations. For this reason, the solar cell module 2 in the first row and the first column is stably supported without wobbling.

尚、1行1列目の太陽電池モジュール2については、3つ以上の固定金具6のうちの1つを仮固定用のスペーサに置き換えて、太陽電池モジュール2をぐらつくことなく安定的に支持しておき、後で述べるような1行1列目と2列目の各太陽電池モジュール2を行列連結金具4を介して連結した後に、仮固定用のスペーサを外しても構わない。   For the solar cell module 2 in the first row and the first column, one of the three or more fixing brackets 6 is replaced with a temporary fixing spacer to stably support the solar cell module 2 without wobbling. The temporary fixing spacers may be removed after the solar cell modules 2 in the first row and the first column and the second column, which will be described later, are connected via the matrix connection fittings 4.

次に、2番目の太陽電池モジュール2を1行2列目の位置に配置し、この太陽電池モジュール2を図14(a)〜図14(d)と同様の手順で各行間連結金具5に係合させる。   Next, the second solar cell module 2 is arranged at the position of the first row and the second column, and this solar cell module 2 is attached to each inter-row connecting bracket 5 in the same procedure as in FIGS. 14 (a) to 14 (d). Engage.

また、1行1列目と2列目の各太陽電池モジュール2の水流れ方向下側の枠部材8が行列連結金具4の係合凹部4dに共に嵌合されてネジ止めされ、各太陽電池モジュール2の水流れ方向上側の枠部材8も別の行列連結金具4の係合凹部4dに共に嵌合されてネジ止めされ、各太陽電池モジュール2が2つの行列連結金具4を介して連結される。   Further, the frame member 8 on the lower side in the water flow direction of each solar cell module 2 in the first row, the first column, and the second column is fitted together with the engagement recess 4d of the matrix connection fitting 4 and screwed to each solar cell. The frame member 8 on the upper side in the water flow direction of the module 2 is also fitted and screwed together in the engagement recess 4 d of another matrix connection fitting 4, and each solar cell module 2 is connected via the two matrix connection fittings 4. The

2番目以降に設置される太陽電池モジュール2については、相互に対向する行方向Aの2本の枠部材8の中央付近と交差するようなそれぞれの箇所(2箇所)にそれぞれの固定金具6を固定配置していることから、2箇所の行間連結金具5に太陽電池モジュール2の枠部材8が係合する。このため、太陽電池モジュール2がぐらつくことになる。ところが、1行1列目の太陽電池モジュール2がぐらつくことなく安定的に支持されているので、1行1列目と2列目の各太陽電池モジュール2の枠部材8が行列連結金具4で連結接続されると、2列目の太陽電池モジュール2もぐらつくことなく安定的に支持される。また、1行1列目の太陽電池モジュール2がぐらつくことなく安定的に支持されているので、行列連結金具4の取付け作業が容易となる。   About the solar cell module 2 installed after the 2nd, each fixing bracket 6 is attached to each place (two places) which cross | intersects the center vicinity of the two frame members 8 of the row direction A which mutually oppose. Since it is fixedly arranged, the frame member 8 of the solar cell module 2 engages with the two row connection fittings 5. For this reason, the solar cell module 2 will wobble. However, since the solar cell module 2 in the first row and the first column is stably supported without wobbling, the frame members 8 of the solar cell modules 2 in the first row and the first column and the second column are the matrix connection fittings 4. When connected, the solar cell modules 2 in the second row are also supported stably without wobbling. In addition, since the solar cell module 2 in the first row and the first column is stably supported without wobbling, the mounting work of the matrix connection fitting 4 is facilitated.

仮に、1行1列目の太陽電池モジュール2がぐらついていたならば、1行1列目と2列目の各太陽電池モジュール2の枠部材8を行列連結金具4に共に係合させる作業が困難になる。   If the solar cell module 2 in the first row and the first column is wobbled, the work of engaging the frame members 8 of the solar cell modules 2 in the first row and the first column and the second column together with the matrix connection fitting 4 is performed. It becomes difficult.

次に、1行3列目以降の太陽電池モジュール2についても、図14(a)〜図14(d)と同様の手順で各行間連結金具5に係合させる。また、隣り合う各太陽電池モジュール
2の水流れ方向下側の枠部材8を行列連結金具4の係合凹部4dに共に嵌合させてネジ止めし、隣り合う各太陽電池モジュール2の水流れ方向上側の枠部材8も別の行列連結金具4の係合凹部4dに共に嵌合させてネジ止めし、隣り合う各太陽電池モジュール2を2つの行列連結金具4を介して連結する。
Next, the solar cell modules 2 in the first row and the third column are also engaged with the inter-row connection fittings 5 in the same procedure as in FIGS. 14 (a) to 14 (d). Moreover, the frame member 8 on the lower side in the water flow direction of each adjacent solar cell module 2 is fitted and screwed together in the engagement recess 4d of the matrix connection fitting 4, and the water flow direction in each adjacent solar cell module 2 is fixed. The upper frame member 8 is also fitted together with the engagement recess 4 d of another matrix connection fitting 4 and screwed, and the adjacent solar cell modules 2 are connected via the two matrix connection fittings 4.

また、1行3列目以降の太陽電池モジュール2についても、前の列の太陽電池モジュール2がぐらつくことなく安定的に支持されていることから、隣り合う各太陽電池モジュール2の枠部材8を行列連結金具4に共に係合させる作業が容易となり、1行目の全ての太陽電池モジュール2がぐらつくことなく安定的に支持される。   In addition, the solar cell modules 2 in the first row and the third column are also supported stably without the wobbling of the solar cell modules 2 in the previous column. The work of engaging the matrix connection fittings 4 together becomes easy, and all the solar cell modules 2 in the first row are stably supported without wobbling.

次に、2行各列の各太陽電池モジュール2についても、図14(a)〜図14(d)と同様の手順で各行間連結金具5に係合させる。あるいは、太陽電池モジュール2を傾斜させず、太陽電池モジュール2の枠部材8を行間連結金具5の各搭載部5fに載せて水平に支持したまま、枠部材8を行間連結金具5の第1留め部5dの押え部5jの下側に押し込んで、枠部材8を行間連結金具5に係合させる。同時に、隣り合う各太陽電池モジュール2の枠部材8を各行列連結金具4に共に係合させる。   Next, the solar cell modules 2 in two rows and columns are also engaged with the inter-row connection fittings 5 in the same procedure as in FIGS. 14 (a) to 14 (d). Alternatively, the frame member 8 is held on the mounting portions 5f of the inter-row connection fitting 5 and horizontally supported while the frame member 8 of the solar cell module 2 is horizontally supported without tilting the solar cell module 2. The frame member 8 is engaged with the inter-row connection fitting 5 by being pushed below the presser portion 5j of the portion 5d. At the same time, the frame members 8 of the adjacent solar cell modules 2 are engaged with the matrix connection fittings 4 together.

このとき、隣り合う各太陽電池モジュール2の水流れ方向下側の枠部材8は、1行目の各太陽電池モジュール2の水流れ方向上側の枠部材8にネジ止めされた行列連結金具4に係合される。このため、2行目の各太陽電池モジュール2の水流れ方向下側の枠部材8に対する行列連結金具4のネジ止めが行われない。また、2行目の各太陽電池モジュール2の水流れ方向上側の枠部材8に対しては行列連結金具4のネジ止めが行われる。   At this time, the frame member 8 on the lower side in the water flow direction of each adjacent solar cell module 2 is connected to the matrix connection fitting 4 screwed to the frame member 8 on the upper side in the water flow direction of each solar cell module 2 in the first row. Engaged. For this reason, the matrix connection metal fitting 4 is not screwed to the frame member 8 on the lower side in the water flow direction of each solar cell module 2 in the second row. Further, the matrix connection fitting 4 is screwed to the frame member 8 on the upper side in the water flow direction of each solar cell module 2 in the second row.

次に、3行目以降の各太陽電池モジュール2についても、同様の手順で、各行間連結金具5及び各行列連結金具4に係合される。 Next, the solar cell modules 2 in the third and subsequent rows are engaged with the inter-row connection fittings 5 and the matrix connection fittings 4 in the same procedure.

尚、図1に示すように各行の両端の行列連結金具4は、太陽電池モジュール2から食み出さないように配置する。 As shown in FIG. 1, the matrix connection fittings 4 at both ends of each row are arranged so as not to protrude from the solar cell module 2.

こうして本実施形態の太陽電池モジュール支持構造を用いた太陽光発電システムが構築される。この太陽光発電システムにおいては、各太陽電池モジュール2の枠部材8の間に行列連結金具4及び行間連結金具5が挟み込まれている。   Thus, a solar power generation system using the solar cell module support structure of the present embodiment is constructed. In this solar power generation system, the matrix connection fitting 4 and the inter-row connection fitting 5 are sandwiched between the frame members 8 of the respective solar cell modules 2.

行間連結金具5の各係合部5m、5nには、前の行における太陽電池モジュール2の水流れ方向上側の枠部材8と次の行における太陽電池モジュール2の水流れ方向下側の枠部材8とがそれぞれ係合する。従って、列方向Bに並ぶ2枚の太陽電池モジュール2の枠部材8が行間連結金具5で連結接続される。   The engaging members 5m and 5n of the inter-row connection fitting 5 include a frame member 8 on the upper side in the water flow direction of the solar cell module 2 in the previous row and a frame member on the lower side in the water flow direction of the solar cell module 2 in the next row. 8 engage with each other. Accordingly, the frame members 8 of the two solar cell modules 2 arranged in the column direction B are connected and connected by the inter-row connection fitting 5.

また、行列連結金具4の各係合凹部4dには、前の行に並ぶ2枚の太陽電池モジュール2の水流れ方向上側の枠部材8と次の行に並ぶ2枚の太陽電池モジュール2の水流れ方向下側の枠部材8とがそれぞれ係合する。従って、2行2列に並ぶ4枚の太陽電池モジュール2の枠部材8が行列連結金具4で連結接続される。   Further, in each engagement recess 4d of the matrix connection fitting 4, the frame member 8 on the upper side of the water flow direction of the two solar cell modules 2 arranged in the previous row and the two solar cell modules 2 arranged in the next row are arranged. The frame members 8 on the lower side in the water flow direction engage with each other. Therefore, the frame members 8 of the four solar cell modules 2 arranged in 2 rows and 2 columns are connected and connected by the matrix connection fitting 4.

このような行列連結金具4及び行間連結金具5による連結は、各太陽電池モジュール2のいずれの間でもなされ、太陽光発電システムの各太陽電池モジュール2全体が一体的に支持される。そして、各行間連結金具5をそれぞれの固定金具6を介して屋根2に固定している。このような構成では、従来の架台の桟等を必要とせず、部品点数の無駄な増加を抑えることができ、太陽光発電に寄与しない無駄なスペースを最小限に抑えることができる。   Such connection by the matrix connection fitting 4 and the inter-row connection fitting 5 is made between any of the solar cell modules 2, and the entire solar cell modules 2 of the photovoltaic power generation system are integrally supported. Then, the inter-row connection fittings 5 are fixed to the roof 2 via the respective fixing fittings 6. Such a configuration does not require a conventional frame or the like, can suppress a wasteful increase in the number of parts, and can minimize a wasteful space that does not contribute to solar power generation.

また、複数の太陽電池モジュール2を1枚ずつ屋根2に固定するのではなく、複数の太陽電池モジュール2を一体化して、1枚目を除く他の各太陽電池モジュール2の2箇所を固定するだけなので、作業効率がよい。   Further, instead of fixing the plurality of solar cell modules 2 to the roof 2 one by one, the plurality of solar cell modules 2 are integrated and two other solar cell modules 2 other than the first one are fixed. Only work efficiency.

更に、1枚目を除く他の各太陽電池モジュール2の2つの固定箇所は、相互に対向する行方向Aの2本の枠部材8の中央付近であるため、これらの太陽電池モジュール2のたわみ等の変形を効果的に抑えることができ、これらの太陽電池モジュール2の荷重をバランスよく支持することができる。   Further, since the two fixed portions of the other solar cell modules 2 except the first one are near the center of the two frame members 8 in the row direction A facing each other, the deflection of these solar cell modules 2 Such deformation can be effectively suppressed, and the load of these solar cell modules 2 can be supported in a well-balanced manner.

また、ネジ13を2本ずつ、行列連結金具4の各穿孔4eを介して2枚の太陽電池モジュール2の枠部材8にそれぞれねじ込んで、行列連結金具4を2枚の太陽電池モジュール2の枠部材8に固定しているので、2枚の太陽電池モジュール2の枠部材8が行列連結金具4を介して電気的に接続され、1行の各太陽電池モジュール2の枠部材8が導通する。このため、各太陽電池モジュール2の接地が容易になる。   Further, two screws 13 are screwed into the frame members 8 of the two solar cell modules 2 through the perforations 4e of the matrix connection fittings 4 respectively, so that the matrix connection fittings 4 are attached to the frames of the two solar cell modules 2. Since it is fixed to the member 8, the frame members 8 of the two solar cell modules 2 are electrically connected via the matrix connection fitting 4, and the frame members 8 of the solar cell modules 2 in one row are conducted. For this reason, the grounding of each solar cell module 2 becomes easy.

更に、図1の箇所Pで示すように行の端に配置された行列連結金具4を、列方向Bに並ぶ2枚の太陽電池モジュール2の外側辺に係合させてネジ止めすれば、2行の太陽電池モジュール2の枠部材8が導通し、行列方向A、Bに配列された全ての太陽電池モジュール2の枠部材8が導通し、各太陽電池モジュール2の接地がより容易になる。   Furthermore, as shown by the point P in FIG. 1, the matrix connection fitting 4 arranged at the end of the row is engaged with the outer side of the two solar cell modules 2 arranged in the column direction B and screwed. The frame members 8 of the solar cell modules 2 in the row conduct, the frame members 8 of all the solar cell modules 2 arranged in the matrix directions A and B conduct, and the grounding of each solar cell module 2 becomes easier.
