図１ないし図５において、１は太陽電池パネル（太陽電池モジュール）で、この太陽電池パネル１は、光起電力効果を利用して太陽光エネルギを直接電気エネルギ（電力）に変換する太陽光発電装置である。   1 to 5, reference numeral 1 denotes a solar cell panel (solar cell module). The solar cell panel 1 uses a photovoltaic effect to convert solar energy directly into electric energy (electric power). Device.

そして、太陽電池パネル１は、図１ないし図５に示されるように、太陽光エネルギを電気エネルギに変換する矩形板状、すなわち例えば上下方向（第１方向）に縦方向である短手方向を有しかつ左右方向（第１方向と直交する第２方向）に横方向である長手方向を有する横長矩形板状の太陽電池パネル本体２と、この太陽電池パネル本体２の周端部を支持する横長矩形環状の周枠体３と、この周枠体３に設けられ太陽電池パネル本体２の裏面を部分的に支持する長手状の複数本の補強部材である裏面支持部材４とを備えている。   As shown in FIGS. 1 to 5, the solar cell panel 1 has a rectangular plate shape for converting solar energy into electric energy, that is, for example, a vertical direction in the vertical direction (first direction). And a horizontally long rectangular plate-shaped solar cell panel body 2 having a longitudinal direction that is transverse in the left-right direction (second direction orthogonal to the first direction), and a peripheral end portion of the solar cell panel body 2 are supported. A horizontally long rectangular ring-shaped peripheral frame body 3 and a back surface support member 4 that is a plurality of longitudinal reinforcing members that are provided on the peripheral frame body 3 and partially support the back surface of the solar cell panel body 2 are provided. .

太陽電池パネル本体２は、例えば矩形板状の透明なガラス体である強化ガラス2aと、この強化ガラス2a内に埋設された薄板状の太陽電池セル（ＰＶセル）2bとにて構成されている。なお、図示しないが、太陽電池セル2bにはこの太陽電池セル2bによって発電された電気を送電する配線が接続され、この配線が集電ボックス等に接続されている。   The solar cell panel body 2 is composed of, for example, a tempered glass 2a, which is a rectangular glass-like transparent glass body, and a thin plate-like solar cell (PV cell) 2b embedded in the tempered glass 2a. . Although not shown, the solar battery cell 2b is connected to a wiring for transmitting electricity generated by the solar battery cell 2b, and this wiring is connected to a current collection box or the like.

太陽電池パネル本体２は、矩形状の平面である表面６と、矩形状の平面である裏面７と、それぞれが細長い矩形状の平面である４つの端面８とを有している。つまり、太陽電池パネル本体２の各面６，７，８の全体が、凹凸のない平坦な平面によって構成されている。   The solar cell panel body 2 has a front surface 6 that is a rectangular plane, a back surface 7 that is a rectangular plane, and four end surfaces 8 that are each an elongated rectangular plane. That is, the entire surfaces 6, 7, and 8 of the solar cell panel body 2 are configured by a flat surface without unevenness.

周枠体３は、例えばアルミニウム等の金属材料からなるもので、太陽電池パネル本体２の周端部を覆うように、その太陽電池パネル本体２に対応した矩形環状に形成されている。   The peripheral frame 3 is made of a metal material such as aluminum, and is formed in a rectangular ring shape corresponding to the solar cell panel main body 2 so as to cover the peripheral end of the solar cell panel main body 2.

周枠体３は、太陽電池パネル本体２の第１方向両端部である上下方向両端部を断面Ｌ字状の緩衝部材13を介して支持する上下１対の第１支持部11と、太陽電池パネル本体２の第２方向両端部である左右方向両端部を断面コ字状の緩衝部材14を介して支持する左右１対の第２支持部12とを有している。   The peripheral frame 3 includes a pair of upper and lower first support portions 11 that support both ends in the vertical direction, which are both ends in the first direction of the solar cell panel body 2, through a buffer member 13 having an L-shaped cross section, and a solar cell. The panel body 2 has a pair of left and right second support portions 12 that support both end portions in the left and right direction, which are both end portions in the second direction, via cushioning members 14 having a U-shaped cross section.

そして、上側の第１支持部11の左端部と下側の第１支持部11の左端部とが左側の第２支持部12にて連結され、上側の第１支持部11の右端部と下側の第１支持部11の右端部とが右側の第２支持部12にて連結され、こうして周枠体３が四方枠状となっている。なお、緩衝部材13，14は、例えば弾性変形可能なゴム材料からなるものである。   The left end portion of the upper first support portion 11 and the left end portion of the lower first support portion 11 are connected by the second support portion 12 on the left side, and the right end portion of the upper first support portion 11 and the lower end portion are connected. The right end portion of the first support portion 11 on the side is connected to the second support portion 12 on the right side, and thus the peripheral frame 3 has a four-sided frame shape. The buffer members 13 and 14 are made of, for example, an elastically deformable rubber material.

下側の第１支持部11は、図３および図４に示されるように、太陽電池パネル本体２の下端部の端面８を緩衝部材13を介して支持する端面支持板16を有している。端面支持板16は、左右方向長手状の矩形板状に形成され、この端面支持板16の幅寸法は例えば太陽電池パネル本体２の厚さ寸法の略３倍である。   As shown in FIGS. 3 and 4, the lower first support portion 11 has an end surface support plate 16 that supports the end surface 8 of the lower end portion of the solar cell panel body 2 via a buffer member 13. . The end face support plate 16 is formed in a rectangular plate shape that is long in the left-right direction, and the width dimension of the end face support plate 16 is, for example, approximately three times the thickness dimension of the solar cell panel body 2.

端面支持板16の太陽電池パネル裏面側の端部には、太陽電池パネル本体２の裏面７の下端部と離間対向する矩形板状の対向板17が端面支持板16に対して直交するように一体に設けられている。   At the end of the end surface support plate 16 on the back surface side of the solar cell panel, a rectangular plate-shaped counter plate 17 that is spaced apart from the lower end portion of the back surface 7 of the solar cell panel body 2 is orthogonal to the end surface support plate 16. It is provided integrally.

端面支持板16の太陽電池パネル表面側の端部における複数箇所（例えば２箇所）には、太陽電池パネル本体２の表面６と接触対向してこの表面６の下端部の一部を支持する三角板状の支持爪18が端面支持板16に対して直交するように一体に設けられている。つまり、太陽電池パネル本体２の表面６の上下端部は、支持爪18のみで押さえられており、支持爪18以外の部分では表面上に出っ張りがない。   Triangular plates that are in contact with the surface 6 of the solar cell panel body 2 and support a part of the lower end portion of the surface 6 at a plurality of locations (for example, two locations) at the end of the end surface support plate 16 on the surface side of the solar cell panel. The support claws 18 are integrally provided so as to be orthogonal to the end face support plate 16. That is, the upper and lower ends of the surface 6 of the solar cell panel body 2 are pressed by the support claws 18 only, and there are no protrusions on the surface other than the support claws 18.

各支持爪（表面支持爪）18は、底辺が太陽電池パネル本体２の表面６の縁位置に位置しかつ頂点がその表面６の縁位置から少し離れた位置に位置する三角板状、すなわち例えば略正三角の板状に形成されている。つまり、図３（ｃ）に示されるように、下側の第１支持部11の支持爪18は、落雪の障害にならないための、底辺が下側に位置し頂点が上側に位置する三角板状のもので、上方に向かって徐々に互いに接近する１対の傾斜面19を有している。   Each support claw (surface support claw) 18 has a triangular plate shape whose bottom is located at an edge position of the surface 6 of the solar cell panel body 2 and whose apex is located slightly away from the edge position of the surface 6. It is formed in a regular triangular plate shape. That is, as shown in FIG. 3 (c), the support claw 18 of the lower first support portion 11 is a triangular plate shape whose bottom is located on the lower side and whose apex is located on the upper side so as not to obstruct snowfall. It has a pair of inclined surfaces 19 that gradually approach each other upward.

また、図４（ｂ）に示されるように、端面支持板16の太陽電池パネル表面側の端部のうち支持爪18が設けられていない端部分16aおよび緩衝部材13の太陽電池パネル表面側の端部13aは、太陽電池パネル本体２の表面６と同一面上に位置している。   Further, as shown in FIG. 4B, the end portion 16a of the end surface support plate 16 on the solar cell panel surface side where the support claw 18 is not provided and the buffer member 13 on the solar cell panel surface side. The end 13a is located on the same plane as the surface 6 of the solar cell panel body 2.

なお、上側の第１支持部11と下側の第１支持部11とが上下対称の構成となっており、上側の第１支持部11の構成部分については、下側の第１支持部11の構成部分と同じ符号を付してその説明を省略する。   The upper first support portion 11 and the lower first support portion 11 have a vertically symmetric configuration, and the lower first support portion 11 is configured with respect to the constituent parts of the upper first support portion 11. The same reference numerals as those in FIG.

左側の第２支持部12は、図５に示されるように、太陽電池パネル本体２の左端部の端面８を緩衝部材14を介して支持する端面支持板21を有している。端面支持板21は、上下方向長手状の矩形板状に形成され、この端面支持板21の幅寸法は例えば太陽電池パネル本体２の厚さ寸法の略３倍である。   As shown in FIG. 5, the second support portion 12 on the left side has an end surface support plate 21 that supports the end surface 8 of the left end portion of the solar cell panel body 2 via a buffer member 14. The end face support plate 21 is formed in a rectangular plate shape that is vertically long, and the width dimension of the end face support plate 21 is, for example, approximately three times the thickness dimension of the solar cell panel body 2.

端面支持板21の太陽電池パネル裏面側の端部には、太陽電池パネル本体２の裏面７の左端部と離間対向する矩形板状の対向板22が端面支持板21に対して直交するように一体に設けられている。   At the end of the end surface support plate 21 on the back surface side of the solar cell panel, a rectangular plate-shaped counter plate 22 that is spaced apart from the left end portion of the back surface 7 of the solar cell panel body 2 is orthogonal to the end surface support plate 21. It is provided integrally.

端面支持板21の太陽電池パネル表面側の端部には、太陽電池パネル本体２の表面６の左端部の全体を緩衝部材14を介して支持する細長い矩形板状の表面支持板23が端面支持板21に対して直交するように一体に設けられている。   At the end of the end surface support plate 21 on the surface side of the solar cell panel, an elongated rectangular plate-like surface support plate 23 that supports the entire left end portion of the surface 6 of the solar cell panel body 2 via the buffer member 14 is end-supported. They are integrally provided so as to be orthogonal to the plate 21.

なお、左側の第２支持部12と右側の第２支持部12とが左右対称の構成となっており、右側の第２支持部12の構成部分については、左側の第２支持部12の構成部分と同じ符号を付してその説明を省略する。   The left side second support part 12 and the right side second support part 12 have a bilaterally symmetric configuration, and the constituent parts of the right side second support part 12 are the configurations of the left side second support part 12. The same reference numerals as those in FIG.

また、図２に示されるように、この太陽電池パネル１においては、長手状の複数本の裏面支持部材４が、両第１支持部11間および両第２支持部12間の両方に架設されて格子状となっている。   Further, as shown in FIG. 2, in the solar cell panel 1, a plurality of longitudinal back surface support members 4 are installed between both the first support portions 11 and between the two second support portions 12. It is a grid.

すなわち例えば、互いに平行な上下方向長手状の５本の裏面支持部材４が周枠体３の第１支持部11間に架設され、かつ、互いに平行な左右方向長手状の２本の裏面支持部材４が周枠体３の第２支持部12間に架設されている。なお、上下方向長手状の裏面支持部材４と左右方向長手状の裏面支持部材４とは、それぞれの裏面支持部材４の一部を構成する交差部25において互いに直交状に交差している。   That is, for example, five back support members 4 that are parallel to each other in the vertical direction are laid between the first support portions 11 of the peripheral frame 3, and two back support members that are parallel to each other in the horizontal direction. 4 is constructed between the second support parts 12 of the peripheral frame 3. In addition, the back support member 4 having a longitudinally long longitudinal shape and the back support member 4 having a longitudinally longitudinal shape intersect each other at an intersecting portion 25 that constitutes a part of each back support member 4.

より具体的には、上下方向長手状の縦長の裏面支持部材４の下端部が下側の第１支持部11の端面支持板16の幅方向中央部に固定され、上下方向長手状の縦長の裏面支持部材４の上端部が上側の第１支持部11の端面支持板16の幅方向中央部に固定されている。また、左右方向長手状の横長の裏面支持部材４の左端部が左側の第２支持部12の端面支持板21の幅方向中央部に固定され、左右方向長手状の横長の裏面支持部材４の右端部が右側の第２支持部12の端面支持板21の幅方向中央部に固定されている。   More specifically, the lower end portion of the vertically long back support member 4 which is vertically long is fixed to the center portion in the width direction of the end surface support plate 16 of the lower first support portion 11 and is vertically long and vertically long. The upper end portion of the back support member 4 is fixed to the center portion in the width direction of the end surface support plate 16 of the upper first support portion 11. In addition, the left end of the horizontally long back support member 4 that is long in the left-right direction is fixed to the center in the width direction of the end face support plate 21 of the left second support portion 12, and the horizontally long back support member 4 that is long in the left-right direction. The right end portion is fixed to the center portion in the width direction of the end surface support plate 21 of the right second support portion 12.

また、各裏面支持部材４は、例えばアルミニウム等の金属材料からなるもので、断面台形状に形成されている。つまり、裏面支持部材４は、図５（ｃ）に示されるように、太陽電池パネル本体２の裏面７の一部を支持する平面状の支持面26と、太陽電池パネル本体２の裏面７から離れる方向に向かって徐々に互いに接近する１対の傾斜面27と、支持面26と平行に位置しその支持面26よりも面積が小さい平行面28とを有している。   Moreover, each back surface supporting member 4 consists of metal materials, such as aluminum, for example, and is formed in cross-sectional trapezoid shape. That is, as shown in FIG. 5C, the back surface support member 4 includes a planar support surface 26 that supports a part of the back surface 7 of the solar cell panel body 2 and the back surface 7 of the solar cell panel body 2. It has a pair of inclined surfaces 27 that gradually approach each other in a direction away from each other, and a parallel surface 28 that is located in parallel with the support surface 26 and has a smaller area than the support surface 26.

図５（ｃ）等から明らかなように、太陽電池パネル本体２の裏面７と裏面支持部材４の支持面26との間には、緩衝部材13，14の厚さ寸法に対応する僅かな隙間30がある。しかし、太陽電池パネル１の使用時には、太陽電池パネル本体２の撓み等により、太陽電池パネル本体２の裏面７と裏面支持部材４の支持面26とが互いに接触して隙間30がなくなる。   As is clear from FIG. 5C and the like, a slight gap corresponding to the thickness dimension of the buffer members 13 and 14 is provided between the back surface 7 of the solar cell panel body 2 and the support surface 26 of the back surface support member 4. There are 30. However, when the solar cell panel 1 is used, the back surface 7 of the solar cell panel body 2 and the support surface 26 of the back surface support member 4 come into contact with each other due to the bending of the solar cell panel body 2 and the gap 30 disappears.

なお、太陽電池パネル１の上下方向長さ寸法は例えば７００〜８００ｍｍ、太陽電池パネル１の左右方向長さ寸法は例えば１４００〜１６００ｍｍである。   In addition, the vertical dimension of the solar cell panel 1 is 700 to 800 mm, for example, and the horizontal dimension of the solar cell panel 1 is 1400 to 1600 mm, for example.

次に、太陽電池パネル１の作用等を説明する。   Next, the operation and the like of the solar cell panel 1 will be described.

図６および図７には、横置きにした太陽電池パネル１の使用状態が示されている。   FIG. 6 and FIG. 7 show the usage state of the solar cell panel 1 placed horizontally.

この使用例では、複数枚、例えば６枚の太陽電池パネル１が上下２段で水平方向に３つ並べられて互いに連結されて１枚の平板状の太陽電池パネル部31が構成されている。   In this usage example, a plurality of, for example, six solar cell panels 1 are arranged in a horizontal direction in two upper and lower stages and connected to each other to constitute one flat solar cell panel portion 31.

この太陽電池パネル部31は、パネル支持部32を介して、建物の屋根33の上に、水平方向に対して傾斜状態となって設置されている。太陽電池パネル本体２の水平方向に対する傾斜角度は、太陽光を効率的に受けることができる最適な角度、すなわち例えば３０度に設定されている。なお、この傾斜角度を適宜調整可能な構成でもよい。   The solar cell panel unit 31 is installed on the roof 33 of the building via the panel support unit 32 in an inclined state with respect to the horizontal direction. The inclination angle of the solar cell panel body 2 with respect to the horizontal direction is set to an optimum angle at which sunlight can be received efficiently, that is, for example, 30 degrees. In addition, the structure which can adjust this inclination angle suitably may be sufficient.

そして、この使用場所が例えば北海道や東北等の積雪地帯であり、冬期間に雪が降ると、その雪は、図７に示されるように、例えば夜のうちに、太陽電池パネル本体２の表面６上に積もる。   And this use place is snowy areas, such as Hokkaido and Tohoku, for example, and when snow falls in the winter period, as shown in FIG. 7, the snow is the surface 6 of the solar cell panel body 2 at night, for example. Stack on top.

このとき、その表面６上に積もった雪の重量に基づく積雪荷重が上方から太陽電池パネル本体２の表面６に作用するが、複数の裏面支持部材４が太陽電池パネル本体２の裏面７を下方から支持しているため、太陽電池パネル本体２が大きく撓むようなことがなく、太陽電池パネル本体２はその積雪荷重に耐えることが可能である。   At this time, a snow load based on the weight of snow accumulated on the surface 6 acts on the surface 6 of the solar cell panel body 2 from above, but the plurality of back surface support members 4 move the back surface 7 of the solar cell panel body 2 downward. Therefore, the solar cell panel body 2 is not greatly bent, and the solar cell panel body 2 can withstand the snow load.

また、太陽が昇り、周囲の気温が上昇すると、太陽電池パネル本体２の表面６上の積雪は、解け始め、落雪の障害になる引っ掛りがないために、太陽電池パネル本体２の傾斜状の表面６上から滑り落ちる。このため、太陽電池パネル本体２の表面６上に積雪が残らず、太陽電池パネル本体２の表面６の一部が雪で覆われて影になるようなことがない。   Further, when the sun rises and the ambient temperature rises, the snow on the surface 6 of the solar cell panel body 2 starts to melt and there is no catch that becomes an obstacle to falling snow. Slide down from the surface 6. For this reason, snow does not remain on the surface 6 of the solar cell panel body 2, and a part of the surface 6 of the solar cell panel body 2 is not covered with snow and becomes a shadow.

さらに、例えば風の強い日等において、比較的強い風圧力が下方から太陽電池パネル本体２の裏面７に作用しても、複数の支持爪18が太陽電池パネル本体２の表面６を上方から支持しているため、太陽電池パネル本体２が周枠体３から外れるようなことがなく、太陽電池パネル本体２はその風圧力に耐えることが可能である。   Furthermore, even if a relatively strong wind pressure acts on the back surface 7 of the solar cell panel body 2 from below on a windy day, for example, the plurality of support claws 18 support the surface 6 of the solar cell panel body 2 from above. Therefore, the solar cell panel main body 2 is not detached from the peripheral frame body 3, and the solar cell panel main body 2 can withstand the wind pressure.

そして、このような太陽電池パネル１によれば、太陽電池パネル本体２の裏面７を支持する長手状の複数本の裏面支持部材（補強部材）４を備えるため、例えば北海道や東北等の積雪地帯で使用され、冬期間に大量の雪が降って太陽電池パネル本体２の表面６上に積もった場合であっても、その積雪荷重に耐えることが可能であり、太陽電池パネル本体２の破損を防止できる。   And according to such a solar cell panel 1, since it is provided with a plurality of longitudinal back surface supporting members (reinforcing members) 4 that support the back surface 7 of the solar cell panel body 2, for example, snowy areas in Hokkaido, Tohoku, etc. Even when a large amount of snow falls and accumulates on the surface 6 of the solar cell panel body 2 during the winter period, it is possible to withstand the snow load and prevent the solar cell panel body 2 from being damaged. it can.

また、複数本の裏面支持部材４が周枠体３の両第１支持部11間および両第２支持部12間の両方に架設されて格子状となっているため、積雪荷重に十分に耐えることが可能であり、太陽電池パネル本体２の破損を効果的に防止できる。   In addition, since the plurality of back surface support members 4 are laid in both the first support portions 11 and the second support portions 12 of the peripheral frame body 3 in a lattice shape, they can sufficiently withstand snow load. The solar cell panel body 2 can be effectively prevented from being damaged.

さらに、周枠体３の第１支持部11は太陽電池パネル本体２の表面６を支持する支持爪18を有するため、上からの積雪荷重に耐えることができるばかりでなく、下からの風圧力にも耐えることができ、太陽電池パネル本体２の破損を防止できる。   Further, since the first support portion 11 of the peripheral frame body 3 has support claws 18 that support the surface 6 of the solar cell panel body 2, not only can it withstand a snow load from above, but also wind pressure from below. The solar cell panel body 2 can be prevented from being damaged.

また、周枠体３の第１支持部11の支持爪18は、底辺が太陽電池パネル本体２の表面６の縁位置に位置しかつ頂点がその表面６の縁位置から離れた位置に位置する三角形状に形成されているため、横置きの傾斜状態に設置して使用することで、落雪の障害にはならず、積雪を太陽電池パネル本体２の表面６上から適切に落下させることができ、よって、太陽電池パネル本体２の破損防止や、エネルギ変換効率の向上等を図ることができる。   Further, the support claw 18 of the first support portion 11 of the peripheral frame 3 is positioned at the edge position of the surface 6 of the solar cell panel body 2 and at the apex at a position away from the edge position of the surface 6. Since it is formed in a triangular shape, it can be properly dropped from the surface 6 of the solar cell panel body 2 without being a hindrance to falling snow when installed in a horizontally inclined state. Therefore, it is possible to prevent damage to the solar cell panel body 2 and improve energy conversion efficiency.

さらに、太陽電池パネル本体２の裏面７は、その一部が複数本の裏面支持部材４にて覆われているが、その残部が露出しているため、この露出部分から放熱でき、パネル発熱のためのエネルギ変換効率低下を防ぐことができ、しかも太陽電池パネル本体２の破損を防止できる。   Furthermore, the back surface 7 of the solar cell panel body 2 is partially covered with a plurality of back surface support members 4, but since the remaining portion is exposed, heat can be dissipated from the exposed portion, and the panel heat can be generated. Therefore, it is possible to prevent the energy conversion efficiency from decreasing, and to prevent the solar cell panel body 2 from being damaged.

なお、上記実施の形態では、５本の縦長の裏面支持部材４が第１支持部11間に架設されかつ２本の横長の裏面支持部材４が第２支持部12間に架設された構成について説明したが、この構成には限定されず、例えば図８に示すように、２本の縦長の裏面支持部材４が第１支持部11間に架設されかつ１本の横長の裏面支持部材４が第２支持部12間に架設された構成でもよい。   In the embodiment described above, five vertically long back support members 4 are laid between the first support portions 11 and two horizontally long back surface support members 4 are laid between the second support portions 12. Although described above, the present invention is not limited to this configuration. For example, as shown in FIG. 8, two vertically long back support members 4 are installed between the first support portions 11 and one horizontally long back support member 4 is provided. It may be constructed between the second support parts 12.

また、例えば図９に示すように、互いに平行な複数本（例えば２本）の縦長の裏面支持部材４が第１支持部11間のみに架設された構成でもよい。   For example, as shown in FIG. 9, a plurality of (for example, two) vertically long back surface supporting members 4 parallel to each other may be constructed only between the first support portions 11.

さらに、例えば図示しないが、互いに平行な複数本の横長の裏面支持部材４が第２支持部12間のみに架設された構成や、１本の縦長の裏面支持部材４が第１支持部11間に架設されかつ１本の横長の裏面支持部材４が第２支持部12間に架設された構成等でもよい。つまり、長手状の複数本の裏面支持部材４が両第１支持部11間および両第２支持部12間のうち少なくともいずれか一方に架設された構成であればよい。   Further, for example, although not shown, a configuration in which a plurality of horizontally long back surface support members 4 that are parallel to each other are installed only between the second support portions 12, or one vertically long back surface support member 4 is between the first support portions 11. A configuration in which one horizontally long back support member 4 is installed between the second support portions 12 may be employed. That is, it is only necessary that the plurality of longitudinal back support members 4 are constructed between at least one of the first support portions 11 and the second support portions 12.

また、周枠体３と裏面支持部材４とが同じ材料で一体に構成されたものでもよく、それぞれが異なる別材料からなるものでもよい。   Moreover, the peripheral frame 3 and the back surface support member 4 may be integrally formed of the same material, or may be made of different materials.

さらに、裏面支持部材４が周枠体３に対して脱着可能に取り付けられた構成等でもよい。   Further, a configuration in which the back surface support member 4 is detachably attached to the peripheral frame 3 may be used.

A configuration having support claws 18 may also be used. And if the 2nd support part 12 is the structure which has the support nail | claw 18 instead of the surface support plate 23, it can also be used even if it installs the solar cell panel 1 in a vertical inclination state. .
