FIG. 1 is a diagram showing a state in which the photovoltaic module 10 is disassembled into a photovoltaic panel 12 that constitutes the photovoltaic module 10 and a frame 14 that holds the peripheral edge of the photovoltaic panel 12.
光起電力パネル１２は、複数の光起電力素子を平面的に配置し、その間を電気的に接続した光起電力素子の集合体である。光起電力素子は、結晶光起電力素子、薄膜光起電力素子等様々の形態のものを用いることができる。
The photovoltaic panel 12 is an aggregate of photovoltaic elements in which a plurality of photovoltaic elements are arranged in a plane and electrically connected therebetween. As the photovoltaic element, various forms such as a crystal photovoltaic element and a thin film photovoltaic element can be used.
光起電力パネル１２は、平面的に複数の光起電力素子を配置して、矩形平面形状の形状としている。光起電力パネル１２の周縁部は、受光面ではなく、フレーム１４によって保持される枠部１３である。
The photovoltaic panel 12 has a rectangular planar shape by arranging a plurality of photovoltaic elements in a plane. The peripheral edge of the photovoltaic panel 12 is not the light receiving surface but the frame 13 held by the frame 14.
フレーム１４は、光起電力パネル１２の周縁部に取り付けられる部材である。フレーム１４は、矩形形状の光起電力パネル１２の４つの辺に合わせて、２つの短辺フレーム部２０，２２と、２つの長辺フレーム部２４，２６の４つの部材で構成される。この短辺フレーム部２０，２２と長辺フレーム部２４，２６とを組み合わせて、額縁のような矩形環状部材としたものがフレーム１４である。
The frame 14 is a member attached to the peripheral portion of the photovoltaic panel 12. The frame 14 is composed of four members, two short- side frame portions 20 and 22 and two long- side frame portions 24 and 26 in accordance with the four sides of the rectangular photovoltaic panel 12. A frame 14 is a rectangular annular member such as a frame by combining the short side frame portions 20 and 22 and the long side frame portions 24 and 26.
短辺フレーム部２０と短辺フレーム部２２は、互いに同じ形状であり、長辺フレーム部２４と長辺フレーム部２６は、互いに同じ形状である。２つの短辺フレーム部２０，２２と、２つの長辺フレーム部２４，２６とは、長手方向の寸法が異なるがほとんどが同じ形状である。
The short side frame portion 20 and the short side frame portion 22 have the same shape, and the long side frame portion 24 and the long side frame portion 26 have the same shape. The two short- side frame portions 20 and 22 and the two long- side frame portions 24 and 26 have almost the same shape although the dimensions in the longitudinal direction are different.
そこで、以下では、特に断らない限り、短辺フレーム部２０に代表させて、フレーム１４の構造について説明を続ける。
Therefore, hereinafter, the structure of the frame 14 will be described by using the short side frame portion 20 as a representative unless otherwise specified.
図２に示されるように、短辺フレーム部２０は、上側張出部３０と、外側支持部３２と、下側保持部３４と、内側支持部３６と、フランジ部３８の各要素で構成される複合形状の枠体である。
As shown in FIG. 2, the short side frame portion 20 is composed of elements of an upper overhang portion 30, an outer support portion 32, a lower holding portion 34, an inner support portion 36, and a flange portion 38. This is a composite-shaped frame.
上側張出部３０は、光起電力パネル１２の内側に向かって光起電力パネル１２の周縁部である枠部１３の上面に沿って張り出す要素である。
The upper projecting portion 30 is an element projecting along the upper surface of the frame portion 13 which is the peripheral portion of the photovoltaic panel 12 toward the inside of the photovoltaic panel 12.
外側支持部３２は、上側張出部３０の外側において下方側に延びてフランジ部３８に接続する要素である。短辺フレーム部２０では、外側支持部３２は上側張出部３０の最外側端から下方に延びているが、場合によっては、最外側端でなく、適当に内側に入った位置から下方に延びるものとしてもよい。
The outer support portion 32 is an element that extends downward on the outside of the upper overhang portion 30 and connects to the flange portion 38. In the short side frame portion 20, the outer support portion 32 extends downward from the outermost end of the upper overhang portion 30, but depending on the case, it extends downward from a position appropriately inside rather than the outermost end. It may be a thing.
下側保持部３４は、光起電力パネル１２の周縁部である枠部１３の下面を支えることで上側張出部３０と外側支持部３２と協働して光起電力パネル１２の周縁部である枠部１３を保持する部材である。
The lower holding portion 34 supports the lower surface of the frame portion 13 that is the peripheral portion of the photovoltaic panel 12, thereby cooperating with the upper projecting portion 30 and the outer support portion 32 at the peripheral portion of the photovoltaic panel 12. It is a member that holds a certain frame portion 13.
下側保持部３４は、上下方向に延びる内側支持部３６の上端側に接続されている。下側保持部３４に加わる荷重は、内側支持部３６によって受けられる。
The lower holding portion 34 is connected to the upper end side of the inner support portion 36 that extends in the vertical direction. A load applied to the lower holding portion 34 is received by the inner support portion 36.
内側支持部３６は、下側保持部３４の内側から下方側に延びてフランジ部３８に接続する要素である。図２の例では、内側支持部３６は、下側保持部３４の最内側端から下方に延びているが、場合によっては、最内側端でなく、適当に内側に入った位置から下方に延びるものとしてもよい。
The inner support portion 36 is an element that extends downward from the inner side of the lower holding portion 34 and connects to the flange portion 38. In the example of FIG. 2, the inner support portion 36 extends downward from the innermost end of the lower holding portion 34. However, in some cases, the inner support portion 36 extends downward from a position appropriately inside rather than the innermost end. It may be a thing.
フランジ部３８は、外側支持部３２の下端側から、光起電力パネル１２に対し、外側に張り出すように設けられる。フランジ部３８を利用して、光起電力モジュール１０を屋根面に取り付けることができる。尚、長辺フレーム部２４，２６のフランジ部は、外側支持部３２の下端側から光起電力パネル１２に対し外側に張り出すように設けても良いし、図１に示されるように内側に張り出すように設けても良い。
The flange portion 38 is provided so as to protrude outward from the lower end side of the outer support portion 32 with respect to the photovoltaic panel 12. Using the flange portion 38, the photovoltaic module 10 can be attached to the roof surface. Incidentally, the flange portions of the long side frame portions 24 and 26 may be provided so as to project outward from the lower end side of the outer support portion 32 with respect to the photovoltaic panel 12, or as shown in FIG. You may provide so that it may overhang.
上側張出部３０の下面壁と、外側支持部３２の内側壁と、下側保持部３４の上面壁によって、短辺フレーム部２０の長手方向に沿って延びる細長い空間が形成される。この空間は、光起電力パネル１２の周縁部を保持する周縁保持空間として用いられる。この周縁保持空間に、光起電力パネル１２の周縁部である枠部１３が挿入され、接着剤１８，１９を用いて、枠部１３と外側支持部３２との間、枠部１３と下側保持部３４との間が固定される。枠部１３と上側張出部３０との間も接着剤で固定してもよい。
An elongated space extending along the longitudinal direction of the short side frame portion 20 is formed by the lower surface wall of the upper overhang portion 30, the inner wall of the outer support portion 32, and the upper surface wall of the lower holding portion 34. This space is used as a peripheral holding space for holding the peripheral portion of the photovoltaic panel 12. A frame portion 13 that is a peripheral portion of the photovoltaic panel 12 is inserted into the peripheral holding space, and the adhesive portion 18 and 19 are used to connect the frame portion 13 and the outer support portion 32 between the frame portion 13 and the lower side. The space between the holding portion 34 is fixed. You may also fix between the frame part 13 and the upper side overhang | projection part 30 with an adhesive agent.
この挿入が行われたときに、枠部１３と上側張出部３０の下面壁の間の隙間と、枠部１３と外側支持部３２の内側壁の間の隙間と、下側保持部３４の上面壁との間の隙間に、充填材１６が配置される。充填材１６としては、シリコン樹脂等の樹脂シール材を用いることができる。
When this insertion is performed, the gap between the frame portion 13 and the lower wall of the upper overhang portion 30, the gap between the frame portion 13 and the inner side wall of the outer support portion 32, and the lower holding portion 34 The filler 16 is disposed in the gap between the top wall. As the filler 16, a resin sealing material such as silicon resin can be used.
下側保持部３４の外側端は、外側支持部３２の内側壁から光起電力パネル１２の内側に向かって所定の間隔を離して配置され、下側保持部３４の外側端と外側支持部３２の内側壁との間には間隙Ｓが設けられる。この間隙Ｓは、短辺フレーム部２０の長手方向の全長に渡って設けられる。このように、間隙Ｓを短辺フレーム部２０の長手方向の全長に渡って設けることで、光起電力モジュール１０の排水性を改善し、信頼性を向上させることができる。この理由について、以下に述べる。
The outer end of the lower holding portion 34 is arranged at a predetermined distance from the inner wall of the outer support portion 32 toward the inside of the photovoltaic panel 12, and the outer end of the lower holding portion 34 and the outer support portion 32 are arranged. A gap S is provided between the inner wall and the inner wall. The gap S is provided over the entire length of the short side frame portion 20 in the longitudinal direction. Thus, by providing the gap S over the entire length of the short side frame portion 20 in the longitudinal direction, the drainage of the photovoltaic module 10 can be improved and the reliability can be improved. The reason for this will be described below.
前述のように、従来の排水用の水抜き孔は、フレームの下側把持部に離散的に設けられていた。この理由は、下側把持部３３２が短辺支持部の側面に直接取り付けられていたためである。然しながら、このような構成では下側把持部の上面と光起電力パネルとの間の空間に侵入した水分が、なかなか抜けない。特に、下側把持部の上面と光起電力パネルとの間に設けられた接着剤或いは充填材中に一端侵入した水分は、なかなか外部に抜けずにその隙間に長期間滞留する。そして、滞留した水分が徐々に蒸発し、水蒸気が光起電力パネル１２中に侵入することによって、光起電力モジュール１０の信頼性が低下するおそれがある。
As described above, the conventional drain holes for drainage are provided discretely in the lower gripping portion of the frame. This is because the lower grip 332 is directly attached to the side surface of the short side support. However, in such a configuration, moisture that has entered the space between the upper surface of the lower gripping portion and the photovoltaic panel does not easily escape. In particular, moisture that has once penetrated into the adhesive or filler provided between the upper surface of the lower gripping part and the photovoltaic panel does not readily escape to the outside and stays in the gap for a long time. And the water | moisture content which stayed evaporated gradually, and there exists a possibility that the reliability of the photovoltaic module 10 may fall because water vapor | steam penetrate | invades into the photovoltaic panel 12. FIG.
そこで、光起電力モジュール１０では、下側保持部３４の外側端と外側支持部３２の内側壁との間に間隙Ｓを、短辺フレーム部２０の長手方向の全長に渡って設けている。このような構成を有する光起電力モジュール１０によれば、水抜き孔を離散的に設けた従来の構造よりも水が抜け易く、信頼性が改善される。
Therefore, in the photovoltaic module 10, a gap S is provided across the entire length in the longitudinal direction of the short side frame portion 20 between the outer end of the lower holding portion 34 and the inner wall of the outer support portion 32. According to the photovoltaic module 10 having such a configuration, water can be easily drained and reliability is improved as compared with the conventional structure in which the drain holes are discretely provided.
外側支持部３２には、予め定めた高さ位置に水抜き孔４０を設けてもよい。予め定めた高さ位置としては、水抜き孔４０の高さ位置が下側保持部３４の上面壁の高さ位置よりも低い位置とされる。水抜き孔４０は、短辺フレーム部２０の長さ方向に沿って連続的な開口部でなく、適当な大きさの開口窓でよい。
The outer support part 32 may be provided with a drain hole 40 at a predetermined height position. As the predetermined height position, the height position of the drain hole 40 is set to a position lower than the height position of the upper surface wall of the lower holding portion 34. The drain hole 40 may not be a continuous opening portion along the length direction of the short side frame portion 20 but may be an opening window of an appropriate size.
すなわち、下側保持部３４の外側端が水抜き用の間隙Ｓで外側支持部３２の内側壁から離間することで、周縁保持空間において充填材１６が埋めきれない部分に溜まる水は、下側保持部３４の下側に容易に排除され、周縁保持空間に滞留することがない。そして、排除された水は、充填材１６や光起電力パネル１２の特性をもはや劣化させる恐れはないので、水抜き孔４０からただちに排除されなくてもよく、例えば水蒸気の形態で時間をかけて光起電力モジュール１０の外側に排除されるものでもよい。そこで、水抜き孔４０は適当な大きさで１つ設けられるものとしてもよい。複数個設ける場合でも、適当な離間間隔としてよい。
That is, when the outer end of the lower holding portion 34 is separated from the inner wall of the outer support portion 32 by the water draining gap S, the water accumulated in the portion where the filler 16 cannot be filled in the peripheral holding space is It is easily removed under the holding part 34 and does not stay in the peripheral holding space. And since the excluded water is no longer likely to deteriorate the characteristics of the filler 16 and the photovoltaic panel 12, it does not have to be immediately removed from the drain hole 40, for example in the form of water vapor. It may be excluded outside the photovoltaic module 10. Therefore, one drain hole 40 may be provided with an appropriate size. Even in the case of providing a plurality, an appropriate separation interval may be used.
フランジ部３８は、建物の屋根に沿って配置され得る要素である。図２に示されるフランジ部３８は、外側に立上壁を有する平坦な板部として示され、立上壁に水抜き孔４２が設けられる。フランジ部３８が有する平坦な板部に代えて、建物の屋根の形状に合わせて、適当な凹凸形状を有するものとしてもよい。但し、屋根の形状の相違にかかわらず、短辺フレーム部２０，２２と長辺フレーム部２４，２６の形状の標準化を図ることを考慮すると、短辺フレーム部２０，２２のフランジ部３８と長辺フレーム部２４，２６のフランジ部３９を共に平坦な板部を有するものとすることが好ましい。
The flange portion 38 is an element that can be arranged along the roof of the building. The flange portion 38 shown in FIG. 2 is shown as a flat plate portion having a rising wall on the outside, and a drain hole 42 is provided in the rising wall. Instead of the flat plate portion of the flange portion 38, an appropriate uneven shape may be used in accordance with the shape of the roof of the building. However, considering the standardization of the shapes of the short side frame portions 20 and 22 and the long side frame portions 24 and 26, regardless of the difference in the shape of the roof, the flange portion 38 and the long side frame portions 20 and 22 are long. Both the flange portions 39 of the side frame portions 24 and 26 preferably have flat plate portions.
なお、短辺フレーム部２２は、短辺フレーム部２０と全く同じ構成で、下側保持部３４の外側端は、外側支持部３２の内側壁から光起電力パネル１２の内側に向かって所定の水抜き用の間隙Ｓを離して配置される。また、必要に応じて外側支持部３２に水抜き孔４０、フランジ部３９の外側の立上壁に水抜き孔４２が設けられる。
The short side frame portion 22 has exactly the same configuration as the short side frame portion 20, and the outer end of the lower holding portion 34 has a predetermined direction from the inner side wall of the outer support portion 32 toward the inside of the photovoltaic panel 12. It arrange | positions apart the clearance gap S for draining water. Moreover, the drainage hole 40 is provided in the outer side support part 32 as needed, and the drainage hole 42 is provided in the standing wall outside the flange part 39. As shown in FIG.
図３に示されるように、周縁保持空間に溜まった水７０は、間隙Ｓから下方に排出され、水抜き孔４０，４２を通って、短辺フレーム部２０の外部に運びだされる。
