Description

本発明は、太陽光により発電する太陽電池パネルを取り付けた太陽電池モジュールに関するものである。   The present invention relates to a solar cell module to which a solar cell panel that generates power by sunlight is attached.

近年、エコエネルギ、環境対策の一環から住宅の屋根や建物の屋上等に設置し、太陽光により発電を行う太陽光発電が注目されている。一般にこの太陽光発電は、単結晶、多結晶、アモルファスシリコン等から成る複数の太陽電池セルを基板上に配列し、電極、配線等を配置して太陽電池モジュールから電力を得るものであり、設置場所や設置面積に応じて複数個の太陽電池モジュールが並設される。   In recent years, solar power generation, which is installed on the roof of a house, the rooftop of a building, etc. and generates power by sunlight, has been attracting attention as part of eco-energy and environmental measures. Generally, this solar power generation is a system in which a plurality of solar cells made of single crystal, polycrystal, amorphous silicon, etc. are arranged on a substrate, and electrodes, wirings, etc. are arranged to obtain power from the solar cell module. A plurality of solar cell modules are arranged in parallel according to the place and installation area.

太陽電池モジュールは図６の斜視図に示すように、枠体１は４辺の枠部２により四角枠状に組み立てられ、枠部２上に設けられた溝部３に太陽電池パネルＰが挿着されている。太陽電池パネルＰには図示しない電極及びケーブルを介して別の太陽電池パネルと連結したり、太陽電池パネルＰにより発電した電力をバッテリに充電している。   As shown in the perspective view of FIG. 6, the solar cell module is assembled in a rectangular frame shape by a frame portion 2 having four sides, and a solar cell panel P is inserted into a groove portion 3 provided on the frame portion 2. Has been. The solar cell panel P is connected to another solar cell panel via an electrode and a cable (not shown), or the battery is charged with electric power generated by the solar cell panel P.

図７はこの太陽電池モジュールの部分断面図を示し、枠部２は内面側が開放された略断面コ字状のアルミニウム製とされ、更に断面コ字状の溝部３が設けられ、この溝部３にガラス４、樹脂板５、太陽電池セル６、樹脂板７、フッ素樹脂フィルム８を積層した太陽電池パネルＰが、防水用樹脂粘着材９を介して挿着されている。   FIG. 7 shows a partial cross-sectional view of this solar cell module, and the frame portion 2 is made of substantially U-shaped aluminum whose inner surface is open, and is further provided with a U-shaped groove portion 3. A solar battery panel P in which the glass 4, the resin plate 5, the solar battery cell 6, the resin plate 7, and the fluororesin film 8 are laminated is inserted through a waterproof resin adhesive material 9.

しかしながら、従来の太陽電池パネルＰの断面コ字状の枠体１は強度が十分ではなく、積雪等により太陽電池パネルＰに大きな荷重が掛かったり、傾斜の強い屋根上等に取り付けた際には、枠体１が歪んだり屈曲して破損する虞れがある。   However, the frame 1 having a U-shaped cross section of the conventional solar cell panel P is not strong enough, and when a large load is applied to the solar cell panel P due to snow or the like, or when it is mounted on a roof with a strong inclination, etc. The frame body 1 may be distorted or bent and damaged.

この枠体１の強度を向上させるために、枠体１の下部に筋交いや支柱等を設けたり、或いは枠体１を小型化することにより対応することがあるが、これらの方法は製造工程や部品点数が増加してしまい、コストが増加することになる。   In order to improve the strength of the frame body 1, there is a case where a brace or a support is provided in the lower part of the frame body 1, or the frame body 1 is downsized. The number of parts increases and the cost increases.

本発明の目的は、上述の課題を解決し、枠体を四角柱状として耐荷重性を向上させた太陽電池ジュールを提供することにある。   An object of the present invention is to provide a solar cell module that solves the above-described problems and has a frame body formed into a quadrangular prism shape and has improved load resistance.

上述の目的を達成するための本発明に係る太陽電池モジュールは、上部に挿入溝を有する中空四角柱状の４個の枠部を組み合わせて枠体を形成し、該枠体上を一周する前記挿入溝に太陽電池パネルを挿着したことを特徴とする。   In order to achieve the above object, the solar cell module according to the present invention comprises a frame body formed by combining four hollow rectangular columnar frame portions having an insertion groove in the upper portion, and the insertion that goes around the frame body. A solar cell panel is inserted into the groove.

本発明に係る太陽電池モジュールによれば、枠部を断面略ロ字状の中空状とすることにより、枠体の強度が向上し、積雪等により大きな荷重が掛かったり傾斜の強い屋根上等に設置しても、枠体が捻れたり撓んだり屈曲することが少ない。   According to the solar cell module of the present invention, by making the frame part a hollow shape having a substantially rectangular cross section, the strength of the frame body is improved, and a heavy load is applied due to snow accumulation or the like on a roof with a strong inclination. Even when installed, the frame body is rarely twisted, bent or bent.

本発明を図１〜図４に図示の実施例に基づいて説明する。   The present invention will be described based on the embodiment shown in FIGS.

図１は本実施の形態における枠部１１の断面図を示しており、枠部１１はアルミニウム合金を押出成型して成形した高さ約４６ｍｍ、幅約２５ｍｍ、平均肉厚約３ｍｍの中空状の四角柱から成り、４個の枠部１１を組み立てて、図２に示すような約１５７４ｍｍ×８０２ｍｍの長方形の枠体１２が構成されている。   FIG. 1 shows a cross-sectional view of a frame portion 11 in the present embodiment. The frame portion 11 is formed by extrusion molding of an aluminum alloy and has a hollow shape having a height of about 46 mm, a width of about 25 mm, and an average wall thickness of about 3 mm. A rectangular frame 12 of about 1574 mm × 802 mm as shown in FIG.

枠部１１の内部の対角隅には、ねじ立て用の溝１３ａ、１３ｂが長手方向に沿って形成されている。また、枠部１１の内壁１１ａの中段には、ボルト規制用の突条１４が長手方向に沿って設けられている。更に、枠部１１の上壁１１ｂの上方の外壁１１ｃ側には、太陽電池パネルＰを固定するための内側を向く断面略コ字状の挿入溝１５が長手方向に沿って付設されている。更に、枠部１１の底部１１ｄの必要個所には、ボルト挿入用の鍵孔状の孔部１６が穿孔されている。   Grooves 13a and 13b for tapping are formed along the longitudinal direction at diagonal corners inside the frame portion 11. In addition, a bolt regulating protrusion 14 is provided in the middle of the inner wall 11a of the frame portion 11 along the longitudinal direction. Further, on the outer wall 11c side above the upper wall 11b of the frame portion 11, an insertion groove 15 having a substantially U-shaped cross section facing the inside for fixing the solar cell panel P is provided along the longitudinal direction. Further, a key hole-like hole 16 for inserting a bolt is drilled at a necessary portion of the bottom 11d of the frame 11.

枠体１２同士を組み付ける場合に、枠体１２の短片側の枠部１１’は、図２に示すように両端において外壁１１ｃと挿入溝１５の上辺のみを残して、枠体１２の幅に相当する長さだけ切り取られ、長片側の枠部１１”と組み合わせられる。そして、図３に示すように短片側の枠部１１’の外壁１１ｃに孔部を穿孔して、ねじ２１を長片側の枠部１１”の溝１３ａ、１３ｂに対してねじ止めすることにより枠部１１’、１１”同士を結合する。   When the frame bodies 12 are assembled together, the frame portion 11 'on the short side of the frame body 12 corresponds to the width of the frame body 12, leaving only the outer wall 11c and the upper side of the insertion groove 15 at both ends as shown in FIG. And is combined with the frame portion 11 ″ on the long piece side. Then, as shown in FIG. 3, a hole is drilled in the outer wall 11c of the frame portion 11 ′ on the short piece side, and the screw 21 is placed on the long piece side. The frame portions 11 ′ and 11 ″ are coupled to each other by screwing the grooves 13 a and 13 b of the frame portion 11 ″.

図４は挿入溝１５にシール部材２２を挿入し、更にこのシール部材２２に太陽電池パネルＰを挿着した状態の断面図を示している。実際には、枠体１２の組立てと並行して、挿入溝１５に従来例と太陽電池パネルＰと同様の積層構造から成る太陽電池パネルＰを挿着する。   FIG. 4 shows a cross-sectional view of a state in which the sealing member 22 is inserted into the insertion groove 15 and the solar cell panel P is further inserted into the sealing member 22. In practice, in parallel with the assembly of the frame body 12, the solar cell panel P having a laminated structure similar to that of the conventional example and the solar cell panel P is inserted into the insertion groove 15.

太陽電池パネルＰの先端部下面においては、加圧のために傾斜を有するテーパ部が生じ、このテーパ部の先端近傍に部材同士を接着している接着剤の層が現れる。この接着剤は吸湿性が大きいために、劣化対策のためには特に厳重な防水対策を採ることが必要となる。   On the lower surface of the front end portion of the solar cell panel P, a tapered portion having an inclination is generated due to pressurization, and an adhesive layer for bonding members to each other appears in the vicinity of the front end of the tapered portion. Since this adhesive has a high hygroscopic property, it is necessary to take a particularly strict waterproofing measure as a countermeasure against deterioration.

シール部材２２は従来の樹脂粘着材に代えて、弾性を有する樹脂系成型品が使用されている。シール部材２２の外面は、枠部１１の上壁１１ｂ及び挿入溝１５の内面に沿って形状とされ、更に内面形状はは太陽電池パネルＰの先端部の形状に合わせられている。また、このシール部材２２は太陽電池パネルＰによる荷重が大きく掛かる上壁１１ｂに面する部分の厚みが大きくされ、この厚みの大きい個所には、空洞２３が設けられ弾性が増すようにされている。   As the seal member 22, a resin-based molded product having elasticity is used instead of the conventional resin adhesive material. The outer surface of the seal member 22 is shaped along the upper wall 11b of the frame 11 and the inner surface of the insertion groove 15, and the inner surface shape is matched with the shape of the tip of the solar cell panel P. Further, the seal member 22 has a large thickness at a portion facing the upper wall 11b to which a large load is applied by the solar battery panel P, and a cavity 23 is provided at a portion where the thickness is large so that elasticity is increased. .

図５はシール部材２２の変形例の断面図であり、接着剤の層が現れる太陽電池パネルＰのテーパ部の先端近傍が確実にシール部材２２の内面に接するように、シール部材２２の該当する個所２２ａは内側に向けて肉盛りされている。   FIG. 5 is a cross-sectional view of a modified example of the seal member 22 and corresponds to the seal member 22 so that the vicinity of the tip of the tapered portion of the solar cell panel P where the adhesive layer appears is in contact with the inner surface of the seal member 22 with certainty. The portions 22a are piled up inward.

このように、太陽電池パネルＰはシール部材２２を介して挿入溝１５に挿着され、防水対策、振動対策がなされるので、従来の樹脂系粘着材のような経年劣化の影響が少ない。   Thus, since the solar cell panel P is inserted into the insertion groove 15 via the seal member 22 and measures for waterproofing and vibration are taken, there is little influence of aging deterioration like a conventional resin-based adhesive material.

この太陽電池モジュールのフレーム等に対する取り付けに際しては、図４に示すように、固定用のボルト２４の頭部２４ａを孔部１６の大径側から枠部１１内に挿入し、ボルト２４のねじ部２４ｂを孔部１６の小幅部に移動する。このとき、ボルト２４の頭部２４ａは枠部１１内の突条１４によって挟み込まれているので、ボルト２４が枠部１１内に落ち込むことはない。その後に、フレーム側からねじ部２４ｂにナットを用いて締め付ける。   When the solar cell module is attached to the frame or the like, as shown in FIG. 4, the head portion 24 a of the fixing bolt 24 is inserted into the frame portion 11 from the large diameter side of the hole portion 16, and the screw portion of the bolt 24 is inserted. 24 b is moved to the narrow part of the hole 16. At this time, the head 24 a of the bolt 24 is sandwiched between the protrusions 14 in the frame portion 11, so that the bolt 24 does not fall into the frame portion 11. Thereafter, the screw part 24b is tightened from the frame side with a nut.

なお、突条１４はボルト２４の規制用として作用するだけでなく、リブの役割も果たしており、枠部１１の機械的強度を向上させる効果もある。   In addition, the protrusion 14 not only acts for regulating the bolt 24 but also plays a role of a rib, and has an effect of improving the mechanical strength of the frame portion 11.

本実施例においては、弾性を有する樹脂系成型品から成るシール部材２２を用いたが、樹脂系部材以外に天然ゴムや合成ゴム等のシ−ル部材を用いることもできる。   In this embodiment, the seal member 22 made of a resin-based molded product having elasticity is used. However, a seal member such as natural rubber or synthetic rubber can be used in addition to the resin-based member.
