以下、本発明の実施形態による太陽光発電ユニットの太陽電池モジュール及びその装着方法について図１から図５に基づいて説明する。
本発明の実施形態による太陽光発電ユニット１は、図１及び図２に示すように、例えば地表面等の設置面２に設置された架台３の上部に複数の太陽電池モジュール４を配列した太陽電池アレイ５を配設している。本実施形態では太陽電池アレイ５は例えば東西方向に傾斜する傾斜面からなる板状に形成され、二組の太陽電池アレイ５は互いに傾斜方向が東方向と西方向に異なる山型または屋根型に設置されているが、同一方向に傾斜していてもよい。
なお、本発明による太陽光発電ユニット１は東西方向に代えて南北方向に設置してもよい。 Hereinafter, the solar cell module of the photovoltaic power generation unit according to the embodiment of the present invention and the mounting method thereof will be described with reference to FIGS. 1 to 5.
As shown in FIGS. 1 and 2, the photovoltaic power generation unit 1 according to the embodiment of the present invention is a sun in which a plurality of solar cell modules 4 are arranged on an upper portion of a gantry 3 installed on an installation surface 2 such as the ground surface, for example. The battery array 5 is arranged. In the present embodiment, the solar cell array 5 is formed in a plate shape consisting of inclined surfaces inclined in the east-west direction, for example, and the two sets of solar cell arrays 5 have a mountain shape or a roof shape in which the inclination directions are different in the east direction and the west direction. Although it is installed, it may be inclined in the same direction.
The photovoltaic power generation unit 1 according to the present invention may be installed in the north-south direction instead of the east-west direction.

架台３は設置面２上に所定間隔で設置された基部７の上部に支持部材８が固定され、その上部に梁部材９が連結されている。各支持部材８は例えばトラス構造であるが、支柱であってもよい。支持部材８は太陽電池アレイ５の傾斜方向に離間して例えば２組設置され、その一方は太陽電池アレイ５の下端部５ａ付近に設置された支持部材８Ａであり、他方は太陽電池アレイ５の上端部５ｂよりも下端部５ａ側に寄った位置に設置された支持部材８Ｂである。梁部材９の上部には垂木をなす取付部材１０がその側面に連結部材１１を介して傾斜状態で固定されている。梁部材９と取付部材１０は平面視で互いに直交する方向に配列されている。 In the gantry 3, the support member 8 is fixed to the upper portion of the base portion 7 installed on the installation surface 2 at predetermined intervals, and the beam member 9 is connected to the upper portion thereof. Each support member 8 has, for example, a truss structure, but may be a support column. For example, two sets of support members 8 are installed so as to be separated from each other in the inclination direction of the solar cell array 5, one of which is a support member 8A installed near the lower end portion 5a of the solar cell array 5, and the other is a support member 8A of the solar cell array 5. The support member 8B is installed at a position closer to the lower end portion 5a than the upper end portion 5b. A mounting member 10 forming a rafter is fixed to the upper portion of the beam member 9 in an inclined state via a connecting member 11 on the side surface thereof. The beam member 9 and the mounting member 10 are arranged in a direction orthogonal to each other in a plan view.

山型に形成された一対の太陽電池アレイ５及び取付部材１０の傾斜姿勢に関し、各上端部５ｂの間にわずかな隙間がある。そして、これら各上端部５ｂから両側の支持部材８Ｂまでの間は作業者が立って歩行や保守点検作業等をできる程度の高さと横幅を有する保守スペース１２を形成している。
保守スペース１２において、上端部５ｂの高さは例えば１８０ｃｍ〜２３０ｃｍ程度、支持部材８Ｂの高さは例えば１００ｃｍ〜１５０ｃｍ程度、一対の支持部材８Ｂ間の距離は例えば１５０ｃｍ程度である。下端部５ａは設置面２から例えば３７ｃｍ程度の高さである。 Regarding the tilted posture of the pair of solar cell arrays 5 and the mounting member 10 formed in a mountain shape, there is a slight gap between the upper end portions 5b. A maintenance space 12 having a height and a width sufficient for an operator to stand and perform walking, maintenance and inspection work, etc. is formed between each of the upper end portions 5b and the support members 8B on both sides.
In the maintenance space 12, the height of the upper end portion 5b is, for example, about 180 cm to 230 cm, the height of the support member 8B is, for example, about 100 cm to 150 cm, and the distance between the pair of support members 8B is, for example, about 150 cm. The lower end portion 5a has a height of, for example, about 37 cm from the installation surface 2.

太陽光発電ユニット１は、例えば一対の太陽電池アレイ５が取付部材１０の傾斜角度に沿って東西方向に対向して設置されている。太陽電池アレイ５は、取付部材１０の傾斜角度に沿って適宜角度、例えば１５°の傾斜角を有しているために日中の午前午後に亘って太陽光を受光することができる。山型をなす一対の太陽電池アレイ５はその上端部５ｂ同士がわずかな間隙を介して対向して配設されている。 In the photovoltaic power generation unit 1, for example, a pair of solar cell arrays 5 are installed facing each other in the east-west direction along an inclination angle of the mounting member 10. Since the solar cell array 5 has an appropriate angle, for example, an inclination angle of 15 ° along the inclination angle of the mounting member 10, it can receive sunlight over the morning and afternoon of the daytime. The pair of solar cell arrays 5 forming a mountain shape are arranged so that their upper end portions 5b face each other with a slight gap.

図２において、所定間隔で配列された取付部材１０には、その上端部５ｂから下端部５ａに向けて複数枚、例えば６枚の太陽電池モジュール４が図３に示す略四角形枠状の枠部(以下、これを既設枠体６というものとする)でねじ１４によってそれぞれ２本の取付部材１０上に固定されている。
そして、太陽電池アレイ５の一部の既設の太陽電池モジュール４が故障または破損したものとして新たな太陽電池モジュール１６に交換する。 In FIG. 2, a plurality of mounting members 10 arranged at predetermined intervals from the upper end portion 5b to the lower end portion 5a, for example, six solar cell modules 4 are framed portions having a substantially quadrangular frame shape as shown in FIG. (Hereinafter, this will be referred to as an existing frame body 6), and each of them is fixed on two mounting members 10 by screws 14.
Then, a part of the existing solar cell module 4 of the solar cell array 5 is replaced with a new solar cell module 16 as if it has failed or is damaged.

本実施形態では、交換に際し、図３に示すように、破損等した太陽電池モジュール４の既設枠体６を残して受光面を含む太陽電池モジュール本体を除去して、新たな太陽電池モジュール１６を設置して、略四角形枠状の枠部(以下、これを新設枠体１７という)を既設枠体６に固定するものとした。即ち、既設枠体６を再生フレームとして再利用する。
既設枠体６には対向する既設枠辺部６ａ、６ｂに各一対のねじ穴Ｐ１が予め形成されている。新設枠体１７には対向する新設枠辺部１７ａ、１７ｂに各一対のねじ穴Ｐ２が予め形成されている。しかも、太陽電池モジュール４、１６の大きさに応じてねじ穴Ｐ１の間隔とねじ穴Ｐ２の間隔は相違している。 In the present embodiment, at the time of replacement, as shown in FIG. 3, the solar cell module main body including the light receiving surface is removed while leaving the existing frame 6 of the damaged solar cell module 4, and a new solar cell module 16 is replaced. After installation, a substantially quadrangular frame-shaped frame portion (hereinafter, this is referred to as a new frame body 17) is fixed to the existing frame body 6. That is, the existing frame 6 is reused as a reproduction frame.
A pair of screw holes P1 are formed in advance in the existing frame side portions 6a and 6b facing the existing frame body 6. A pair of screw holes P2 are previously formed in the new frame body 17 on the side portions 17a and 17b of the new frame facing each other. Moreover, the spacing between the screw holes P1 and the spacing between the screw holes P2 are different depending on the sizes of the solar cell modules 4 and 16.

なお、既設の太陽電池モジュール４の既設枠体６は図３及び図４に示すように、対向する２辺の既設枠辺部６ａ、６ｂが２本の取付部材１０にそれぞれねじ１４とナット１５で固定されている。取付部材１０は断面略コの字状に形成されている（図８参照）。
既設枠体６は、図４に示すように、既設の太陽電池モジュール４の略板状の太陽電池モジュール本体１３を嵌合するための断面略コの字状の受け部１８ａと、受け部１８ａの下側に形成した中空枠部１９ａと、中空枠部１９ａの下面を内側に延長させた載置部２０ａとからなる断面形状で四辺が形成されている。載置部２０ａは取付部材１０の上に設置され、取付部材１０の上面部の裏側から載置部２０ａにねじ１４を締め込んでナット１５で固定されている。なお、取付部材１０の上面部には予め所定間隔でねじ穴が形成されているが、捩じ込み時に形成してもよい。 As shown in FIGS. 3 and 4, the existing frame body 6 of the existing solar cell module 4 has two opposite side existing frame side portions 6a and 6b on two mounting members 10, respectively, with screws 14 and nuts 15. It is fixed with. The mounting member 10 is formed in a substantially U-shaped cross section (see FIG. 8).
As shown in FIG. 4, the existing frame 6 has a substantially U-shaped receiving portion 18a and a receiving portion 18a for fitting the substantially plate-shaped solar cell module main body 13 of the existing solar cell module 4. Four sides are formed in a cross-sectional shape including a hollow frame portion 19a formed on the lower side and a mounting portion 20a in which the lower surface of the hollow frame portion 19a is extended inward. The mounting portion 20a is installed on the mounting member 10, and the screw 14 is tightened from the back side of the upper surface portion of the mounting member 10 to the mounting portion 20a and fixed by the nut 15. Although screw holes are formed in advance at predetermined intervals on the upper surface of the mounting member 10, they may be formed at the time of screwing.

しかも、本実施形態では、図３に示すように、既設枠体６内に新たな太陽電池モジュール１６が取り付けられている。この新設の太陽電池モジュール１６は既設の太陽電池モジュール４よりも受光面積が小さく縦横方向の寸法が小さい小型のものとする。
一般に、既設の太陽光発電ユニット１は設置後、数年〜１０数年の年月が経過していずれかの太陽電池モジュール４が故障することがある。その場合、故障した太陽電池モジュール４の交換時期には、技術の進歩により設置時より小さい大きさの太陽電池モジュール１６で同程度以上の発電出力をだせるように進歩している。そのため、本実施形態では新設の太陽電池モジュール１６として故障等した太陽電池モジュール４より縦横寸法の小さい小型のものを設置した。 Moreover, in the present embodiment, as shown in FIG. 3, a new solar cell module 16 is mounted in the existing frame body 6. The newly installed solar cell module 16 has a smaller light receiving area and smaller vertical and horizontal dimensions than the existing solar cell module 4.
In general, one of the solar cell modules 4 may fail after several years to several years have passed since the existing photovoltaic power generation unit 1 was installed. In that case, at the time of replacement of the failed solar cell module 4, due to technological progress, the solar cell module 16 having a size smaller than that at the time of installation is advancing so as to generate power output of the same level or more. Therefore, in the present embodiment, as the newly installed solar cell module 16, a small one having a smaller vertical and horizontal dimension than the failed solar cell module 4 is installed.

次に既設枠体６と新設の太陽電池モジュール１６の固定構造について図３乃至図６により説明する。新設の太陽電池モジュール１６は既設の太陽電池モジュール４と同様に略四角形板状で形成され、縦横方向の寸法が比較的短く形成された小型のものである。そのため、新設の太陽電池モジュール１６は既設枠体６内に納められている。また、新設の太陽電池モジュール１６の下面側には対向する２本の取付部材１０に斜めに連結されたブレース２２が設置され、両端部に形成したねじ穴Ｐ３を通してねじ１４によって連結されている。
図５に示すように、ブレース２２の一端は取付部材１０と新設枠体１７の間に挟持されてねじ１４で連結されている。既設枠体６と新設枠体１７の断面形状はほぼ同一であるが、両者を区別するために、新設枠体１７の構成を受け部１８ｂ、中空枠部１９ｂ、載置部２０ｂと表示する。 Next, the fixed structure of the existing frame body 6 and the newly installed solar cell module 16 will be described with reference to FIGS. 3 to 6. Like the existing solar cell module 4, the newly installed solar cell module 16 is formed in a substantially quadrangular plate shape, and is a small one having relatively short vertical and horizontal dimensions. Therefore, the newly installed solar cell module 16 is housed in the existing frame body 6. Further, on the lower surface side of the newly installed solar cell module 16, braces 22 obliquely connected to two opposing mounting members 10 are installed, and are connected by screws 14 through screw holes P3 formed at both ends.
As shown in FIG. 5, one end of the brace 22 is sandwiched between the mounting member 10 and the new frame body 17 and connected by screws 14. The cross-sectional shapes of the existing frame body 6 and the new frame body 17 are almost the same, but in order to distinguish between them, the structure of the new frame body 17 is indicated as a receiving portion 18b, a hollow frame portion 19b, and a mounting portion 20b.

図３において、既設枠辺部６ａ、６ｂの各２つのねじ穴Ｐ１は一対の取付部材１０上に位置し、ねじ１４でそれぞれ固定されている。一方、新設枠辺部１７ａ、１７ｂの各ねじ穴Ｐ２は一方だけ取付部材１０上に位置し、他方は取付部材１０から外れた位置にある。
図５において、既設枠体６の一方の既設枠辺部６ａは載置部２０ａと一方の取付部材１０の上面部とがねじ１４によって連結されている。新設枠体１７の新設枠辺部１７ａは既設枠辺部６ａの載置部２０ａの上に載置され、中空枠部１９ａに当接して設置されている。
しかも、ねじ１４及びナット１５との干渉を避けるために中空枠部１９ｂに凹部１９ｂａが形成されている。そして、取付部材１０の上面部とブレース２２と新設枠辺部１７ｂの載置部２０ｂとが積層されてねじ１４とナット１５で連結されている。 In FIG. 3, each of the two screw holes P1 of the existing frame side portions 6a and 6b are located on the pair of mounting members 10 and are fixed by screws 14. On the other hand, only one of the screw holes P2 of the new frame side portions 17a and 17b is located on the mounting member 10, and the other is located off the mounting member 10.
In FIG. 5, one of the existing frame side portions 6a of the existing frame body 6 has a mounting portion 20a and an upper surface portion of one mounting member 10 connected by screws 14. The new frame side portion 17a of the new frame body 17 is placed on the mounting portion 20a of the existing frame side portion 6a, and is installed in contact with the hollow frame portion 19a.
Moreover, a recess 19ba is formed in the hollow frame portion 19b in order to avoid interference with the screw 14 and the nut 15. Then, the upper surface portion of the mounting member 10, the brace 22, and the mounting portion 20b of the new frame side portion 17b are laminated and connected by the screw 14 and the nut 15.

図６に示すように、他方の取付部材１０の上には既設枠辺部６ａが設置され、その載置部２０ａがねじ１４で連結されている。しかも、載置部２０ａの上には新設枠辺部１７ａが載置され、図５と同様の構成を有している。しかも、新設枠辺部１７ａはねじ穴Ｐ２の位置がずれているため載置部２０ｂはねじ１４で固定されていない。
そして、図７に示すように、他方の新設枠辺部１７ｂはブレース２２上に載置され、ブレース２２と載置部２０ｂとがねじ穴Ｐ２、Ｐ３を通してねじ１４とナット１５によって固定されている。新設枠辺部１７ｂの載置部２０ｂは一方の取付部材１０上に載置されて、取付部材１０の上面部から他方のねじ穴Ｐ２を通してねじ１４とナット１５で固定されている。また、図８に示すように、ブレース２２の他端部は取付部材１０の上で上面部とねじ１４で固定されている。 As shown in FIG. 6, an existing frame side portion 6a is installed on the other mounting member 10, and the mounting portion 20a is connected by screws 14. Moreover, a new frame side portion 17a is mounted on the mounting portion 20a, and has the same configuration as that of FIG. Moreover, since the screw holes P2 of the new frame side portion 17a are misaligned, the mounting portion 20b is not fixed by the screws 14.
Then, as shown in FIG. 7, the other new frame side portion 17b is mounted on the brace 22, and the brace 22 and the mounting portion 20b are fixed by the screw 14 and the nut 15 through the screw holes P2 and P3. ..

そのため、他方のねじ穴Ｐ２の１つはブレース２２にねじ１４で固定することで、新設の太陽電池モジュール１６の固定強度を確保している。しかもブレース２２の両端はそれぞれ取付部材１０にねじ１４で固定されている。 In the present embodiment, the sizes of the existing solar cell module 4 and the newly installed solar cell module 16 are different, and the screw holes P1 of the existing frame side portions 6a and 6b facing each other are located on the mounting member 10. It is fixed with a screw 14. On the other hand, since the screw holes P2 are formed in the newly installed frame side portions 17a and 17b facing each other according to their lengths, one screw hole P2 is located on the mounting member 10 and is fixed to the upper surface portion thereof by the screw 14. However, the other screw hole P2 is located at a position separated from the mounting member 10.
Therefore, one of the other screw holes P2 is fixed to the brace 22 with a screw 14 to secure the fixing strength of the newly installed solar cell module 16. Moreover, both ends of the brace 22 are fixed to the mounting member 10 with screws 14.

即ち、図２に示すように、太陽光発電ユニット１の太陽電池アレイ５の一部の太陽電池モジュール４が故障や破損等した場合、図３及び図４に示すようにその四角形枠状の既設枠体６を除いて太陽電池モジュール本体１３等の内部の部品を撤去する。残った既設枠体６は対向する既設枠辺部６ａ、６ｂが一対の取付部材１０にねじ固定されている。 The photovoltaic power generation unit 1 according to the present embodiment has the above-described configuration, and then a replacement method by repairing or the like of the existing solar cell module 4 will be described.
That is, as shown in FIG. 2, when a part of the solar cell modules 4 of the solar cell array 5 of the photovoltaic power generation unit 1 breaks down or is damaged, as shown in FIGS. 3 and 4, the existing quadrangular frame shape thereof is installed. Except for the frame body 6, internal parts such as the solar cell module main body 13 are removed. In the remaining existing frame body 6, the existing frame side portions 6a and 6b facing each other are screw-fixed to the pair of mounting members 10.

次に一対の取付部材１０間に斜めにブレース２２を設置し、ブレース２２の他端を取付部材１０の上面部とねじ１４で固定する。次いで、既設枠体６内の一対の取付部材１０上に新設の太陽電池モジュール１６を設置する。
その際、図３及び図５に示すように、新設枠体１７の一方の新設枠辺部１７ａを既設枠辺部６ａの載置部２０ａの上に載置させ、その載置部２０ｂを取付部材１０の上面部との間にブレース２２の一端部を挟んでねじ１４で固定する。また、図７に示すように、他方の新設枠辺部１７ｂをブレース２２の中間部に載置させてねじ１４で固定する。
このようにして新設の太陽電池モジュール１６を既設枠体６を介して取付部材１０に固定できる。 Next, the brace 22 is diagonally installed between the pair of mounting members 10, and the other end of the brace 22 is fixed to the upper surface of the mounting member 10 with a screw 14. Next, the newly installed solar cell module 16 is installed on the pair of mounting members 10 in the existing frame body 6.
At that time, as shown in FIGS. 3 and 5, one of the new frame side portions 17a of the new frame body 17 is placed on the mounting portion 20a of the existing frame side portion 6a, and the mounting portion 20b is mounted. One end of the brace 22 is sandwiched between the upper surface of the member 10 and the brace 22 and fixed with the screw 14.

図９乃至図１１は上述した実施形態の変形例による太陽電池モジュールを示すものである。
図９に示す第一変形例では、第一実施形態における太陽電池モジュール１６の交換構造と比較して、ブレース２２の設置位置が異なる。本第一変形例では、ブレース２２は一端部を他方の取付部材１０の上面部にねじ固定し、中間部を新設枠体１７の新設枠辺部１７ｂにねじ固定して連結する。そして、ブレース２２の他端部は一方の取付部材１０の上面部と既設枠辺部６ｂの載置部２０ａとの間に挟んでねじ１４とナット１５で固定した。
本第一変形例では、ブレース２２の他端部を既設枠辺部６ｂと取付部材１０との間に介在させて一体にねじ固定できる。 9 to 11 show a solar cell module according to a modification of the above-described embodiment.
In the first modification shown in FIG. 9, the installation position of the brace 22 is different from that of the replacement structure of the solar cell module 16 in the first embodiment. In this first modification, one end of the brace 22 is screw-fixed to the upper surface of the other mounting member 10, and the intermediate portion is screw-fixed to the new frame side portion 17b of the new frame body 17 to be connected. The other end of the brace 22 was sandwiched between the upper surface of one mounting member 10 and the mounting portion 20a of the existing frame side portion 6b, and fixed with screws 14 and nuts 15.
In this first modification, the other end of the brace 22 can be interposed between the existing frame side portion 6b and the mounting member 10 and screw-fixed integrally.

図１０に示す第二変形例では、第一実施形態における太陽電池モジュール１６の交換構造と比較して、ブレース２５の形状と設置位置が異なる。本第二変形例では、ブレース２５は略くの字状に屈曲しており、その一端部を他方の取付部材１０の上面部と既設枠辺部６ａの載置部２０ａとの間に介在させ、上面部からねじ１４を締め込んでナット１５で締め付け固定した。そして、ブレース２５の他端部は上述の第一変形例と同様に一方の取付部材１０の上面部と既設枠辺部６ｂの載置部２０ａとの間に挟んでねじ１４とナット１５で固定した。しかも、ブレース２５の中間部は新設枠体１７の新設枠辺部１７ｂの載置部２０ｂとねじ１４で固定した。 In the second modification shown in FIG. 10, the shape and installation position of the brace 25 are different from those of the replacement structure of the solar cell module 16 in the first embodiment. In this second modification, the brace 25 is bent in an abbreviated shape, and one end thereof is interposed between the upper surface portion of the other mounting member 10 and the mounting portion 20a of the existing frame side portion 6a. , The screw 14 was tightened from the upper surface portion and tightened and fixed with the nut 15. Then, the other end of the brace 25 is sandwiched between the upper surface of one mounting member 10 and the mounting portion 20a of the existing frame side portion 6b and fixed with screws 14 and nuts 15 as in the first modification described above. did. Moreover, the intermediate portion of the brace 25 was fixed to the mounting portion 20b of the new frame side portion 17b of the new frame body 17 with screws 14.

更に、新設枠辺部１７ｂの既設のねじ穴Ｐ２が一方の取付部材１０上に位置するため、ねじ１４で上面部と載置部２０ｂをねじ穴Ｐ２を通してねじ１４とナット１５で固定した。
本第二変形例によれば、１枚のブレース２５を折り曲げ形成することで、対向する既設枠辺部６ａ、６ｂに固定して、その上で新設の太陽電池モジュール１６を新設枠体１７で固定できるため、新設の太陽電池モジュール１６の保持強度が高くなる。 Further, since the existing screw hole P2 of the new frame side portion 17b is located on one mounting member 10, the upper surface portion and the mounting portion 20b are fixed by the screw 14 and the nut 15 through the screw hole P2.
According to this second modification, one brace 25 is bent and formed to be fixed to the existing frame side portions 6a and 6b facing each other, and the new solar cell module 16 is mounted on the new frame body 17 on the opposite existing frame side portions 6a and 6b. Since it can be fixed, the holding strength of the newly installed solar cell module 16 is increased.

図１１に示す第三変形例では、ブレース２２、２５を設置しない点で上述の実施形態や他の変形例や実施形態の設置位置が異なる。本第三変形例では、一対の取付部材１０と既設枠体６の各既設枠辺部６ａ及び既設枠辺部６ｂとの各交差部に略Ｌ字状の止め金具２７を設置した。なお、止め金具２７の両端部にはねじ穴Ｐ３が予め形成されている。
そして、既設枠体６の対向する既設枠辺部６ａ、６ｂに形成されたねじ穴Ｐ１を通して取付部材１０の上面部と既設枠辺部６ａ、６ｂの載置部２０ａとをねじ１４とナット１５で固定している。 In the third modified example shown in FIG. 11, the above-described embodiment and other modified examples and the installation positions of the embodiments are different in that the braces 22 and 25 are not installed. In this third modification, substantially L-shaped fasteners 27 are installed at the intersections of the pair of mounting members 10 and the existing frame side portions 6a and the existing frame side portions 6b of the existing frame body 6. Screw holes P3 are formed in advance at both ends of the fastener 27.
Then, through the screw holes P1 formed in the existing frame side portions 6a and 6b of the existing frame body 6, the upper surface portion of the mounting member 10 and the mounting portion 20a of the existing frame side portions 6a and 6b are screwed 14 and the nut 15. It is fixed with.

しかも、既設枠体６内に小型で新設の太陽電池モジュール１６を設置する際、新設枠体１７は比較的小型であるため、既設枠辺部６ａ、６ｂと新設枠辺部１７ａ、１７ｂとに予め設置したねじ穴Ｐ１、Ｐ２の位置がずれている。即ち、既設枠辺部６ａ、６ｂのねじ穴Ｐ１は取付部材１０上に位置するが、新設枠辺部１７ａ、１７ｂのねじ穴Ｐ２は取付部材１０から外れた位置になる。 Moreover, when a small and newly installed solar cell module 16 is installed in the existing frame body 6, since the new frame body 17 is relatively small, the existing frame side portions 6a and 6b and the new frame side portions 17a and 17b are used. The positions of the screw holes P1 and P2 installed in advance are misaligned. That is, the screw holes P1 of the existing frame side portions 6a and 6b are located on the mounting member 10, but the screw holes P2 of the new frame side portions 17a and 17b are located outside the mounting member 10.

そのため、取付部材１０の上面部と既設枠辺部６ａ，６ｂの載置部２０ａとの間に止め部材としての止め金具２７の一端部を介在させてねじ１４とナット１５で固定し、止め金具２７の他端部を新設枠辺部１７ａ、１７ｂの載置部２０ｂに重ねてねじ１４とナット１５で固定した。なお、止め金具２７の両端部には予めねじ穴Ｐ３が形成されている。
これによって、新設の太陽電池モジュール１６は対向する新設枠辺部１７ａ、１７ｂの既設の一対のねじ穴Ｐ２の下部に設けた止め金具２７を介して既設枠体６及び取付部材１０に堅固にねじ固定できる。 Therefore, one end of the fixing bracket 27 as a fixing member is interposed between the upper surface portion of the mounting member 10 and the mounting portion 20a of the existing frame side portions 6a and 6b, and fixed with the screw 14 and the nut 15. The other end of 27 was placed on the mounting portions 20b of the new frame side portions 17a and 17b and fixed with screws 14 and nuts 15. Screw holes P3 are formed in advance at both ends of the fastener 27.
As a result, the newly installed solar cell module 16 is firmly screwed to the existing frame body 6 and the mounting member 10 via the fastener 27 provided under the existing pair of screw holes P2 of the new frame side portions 17a and 17b facing each other. Can be fixed.

また、図１２は既設の太陽電池モジュール４の変形例による既設枠体２９と新設枠体３０を示すものである。これらの対向する既設枠辺部２９ａ、２９ｂ、新設枠辺部３０ａ、３０ｂは例えば断面略Ｅ字状に形成されていてもよい。この場合、既設枠辺部２９ａ、２９ｂ、新設枠辺部３０ａ、３０ｂの上側の断面コの字状の受け部３１ａ、３１ｂで太陽電池モジュール本体１３を嵌合させ、下側の下面部３２ａ、３２ｂで取付部材１０の上面部やブレース２２，２５等とねじ１４とナット１５で固定してもよい。なお、図１２（ａ）は実施形態の図４に相当する構成であり、図１２（ｂ）は同じく図５に相当する構成を示している。 Further, FIG. 12 shows an existing frame body 29 and a new frame body 30 according to a modified example of the existing solar cell module 4. The existing frame side portions 29a and 29b and the new frame side portions 30a and 30b facing each other may be formed, for example, in a substantially E-shaped cross section. In this case, the solar cell module main body 13 is fitted by the receiving portions 31a and 31b having a U-shaped cross section on the upper side of the existing frame side portions 29a and 29b and the new frame side portions 30a and 30b, and the lower lower surface portion 32a, 32b may be fixed to the upper surface of the mounting member 10, braces 22, 25, etc. with screws 14 and nuts 15. Note that FIG. 12A shows a configuration corresponding to FIG. 4 of the embodiment, and FIG. 12B shows a configuration corresponding to FIG. 5 as well.

なお、上述した実施形態や変形例等では、既設枠体６の一辺の既設枠辺部６ａに新設枠体１７の一辺の新設枠辺部１７ａをねじ１４で連結固定したが、連結固定部は必ずしも一辺である必要はなく、交差する二辺同士をねじ１４で連結固定してもよい。新設枠辺部１７ａのねじ穴Ｐ２が取付部材１０からずれたとしても、少なくとも既設枠体６の載置部２０ａを長く設定して新設枠体１７の載置部２０ｂと重ねてねじ１４で連結固定してもよい。
また、図５において、既設枠体６の載置部２０ａを新設枠体１７の載置部２０ｂの下に延ばしてねじ穴Ｐ１、Ｐ２を重ねる構成を採用することで、既設枠体６の載置部２０ａと新設枠体１７の載置部２０ｂを直接ねじ１４で連結固定できる。
また、ブレース２２，２５と止め金具２７は仲介部材に含まれる。 In the above-described embodiments and modifications, the new frame side portion 17a on one side of the new frame body 17 is connected and fixed to the existing frame side portion 6a on one side of the existing frame body 6 with screws 14. It does not necessarily have to be one side, and two intersecting sides may be connected and fixed with screws 14. Even if the screw hole P2 of the new frame side portion 17a deviates from the mounting member 10, at least the mounting portion 20a of the existing frame body 6 is set to be long and overlapped with the mounting portion 20b of the new frame body 17 and connected with the screw 14. It may be fixed.
Further, in FIG. 5, by adopting a configuration in which the mounting portion 20a of the existing frame body 6 is extended under the mounting portion 20b of the new frame body 17 and the screw holes P1 and P2 are overlapped, the existing frame body 6 is mounted.
