Abstract

<P>PROBLEM TO BE SOLVED: To provide a solar cell panel capable of being installed on roof faces adjacent to each other and different in the gradient direction to increase electric power generation and capable of surely securing waterproof performance between the roof faces. <P>SOLUTION: The solar cell panel 20 is provided with a pair of light accepting faces 21A integrally formed to cover a pair of roof faces adjacent to each other and different in the gradient direction. When the solar cell panel 20 as described above is installed over the adjacent roof faces, a junction of solar panels as experienced in the roof of the prior arts is not formed along a descending ridge formed by the roof faces so that the waterproof performance of the roof can be sufficiently secured. Further, because the waterproof performance of the descending ridge is enhanced by using the solar cell panel 20, coping or the like can be omitted to simplify construction work. Because the solar cell panel can be installed on the descending ridge of the roof by using the solar cell panel 20, electric power generation greater as compared with the conventional panels can be obtained. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、太陽電池パネルに係り、詳しくは、傾斜方向の異なる隣接した複数の屋根面に跨って配置される太陽電池パネルに関する。   The present invention relates to a solar cell panel, and more particularly, to a solar cell panel arranged across a plurality of adjacent roof surfaces having different inclination directions.

従来より、建物の屋根面に縦横に配列された屋根葺材である複数の太陽電池パネルで、太陽光を電力に変換する太陽電池付屋根を形成することが知られている。太陽電池パネルは、正方形や長方形の四角形状に形成されたものが一般的であり、屋根面の傾斜方向に沿って、屋根面に取り付けられたレール状の支持部材に固定されている（特許文献１等参照）。太陽電池付屋根の形式としては、太陽電池パネルが通常四角形状であることから、屋根面の傾斜方向に沿って太陽電池パネルを配列しやすい切妻式の屋根が一般的である。   2. Description of the Related Art Conventionally, it is known to form a roof with solar cells that converts sunlight into electric power by using a plurality of solar cell panels that are roof coverings arranged vertically and horizontally on the roof surface of a building. The solar cell panel is generally formed in a square or rectangular quadrilateral shape, and is fixed to a rail-like support member attached to the roof surface along the inclination direction of the roof surface (Patent Literature). 1 etc.). As a type of the roof with solar cells, since the solar cell panel is usually rectangular, a gable roof that can easily arrange the solar cell panels along the inclination direction of the roof surface is common.

一方、太陽電池付屋根の形式として、寄棟式の屋根とする場合がある。このような場合、四角形状の太陽電池パネルを屋根面に配列すると、屋根面の角部（特に下り棟付近）等に大きな余白部分が生じてしまう。そこで、屋根の下り棟に沿った斜辺を有する三角形状や台形状に形成された太陽電池パネルを、下り棟に沿って屋根面に複数配列し、残り部分に四角形状の太陽電池パネルを縦横に複数配列することが考えられる。これにより、寄棟式屋根の屋根面に、たとえば、三角形状および四角形状の太陽電池パネル、あるいは台形状および四角形状の太陽電池パネルを隙間なく配列することができる。   On the other hand, as a form of the roof with solar cells, a dormitory roof may be used. In such a case, when a rectangular solar cell panel is arranged on the roof surface, a large blank portion is generated at a corner portion (particularly near the down wing) of the roof surface. Therefore, a plurality of solar panels formed in a triangular shape or trapezoidal shape with a hypotenuse along the descending ridge of the roof are arranged on the roof surface along the descending ridge, and the rectangular solar panel is vertically and horizontally arranged in the remaining portion. Multiple arrangements are possible. Thereby, for example, triangular and quadrangular solar cell panels or trapezoidal and quadrangular solar cell panels can be arranged without gaps on the roof surface of the dormitory roof.

特開平９−３２２０６号公報JP-A-9-32206

ところで、より大きな電力を確保するために、屋根面にできるだけ隙間なく太陽電池パネルを配列することが考えられる。具体的には、上述したような三角形状または台形状の太陽電池パネルを、下り棟を挟んで両側の屋根面（下り棟を形成する一対の屋根面）にそれぞれ配列することが考えられる。
しかし、このように三角形状または台形状太陽電池パネルを配列すると、下り棟の部分には、太陽電池パネルの斜辺同士の連結部が生じるから、この部分での防水性能が十分に確保されないという心配がある。 By the way, in order to secure a larger electric power, it is conceivable to arrange the solar cell panels on the roof surface with as little gap as possible. Specifically, it is conceivable to arrange the above-described triangular or trapezoidal solar cell panels on both roof surfaces (a pair of roof surfaces forming the descending ridge) across the descending ridge.
However, if the triangular or trapezoidal solar cell panels are arranged in this way, a connecting portion between the oblique sides of the solar cell panels is formed in the downward ridge portion, so that the waterproof performance in this portion is not sufficiently secured. There is.

本発明の目的は、傾斜方向の異なる隣接した屋根面に配置して発電量を大きくでき、かつ、各屋根面間の防水性能も確実に確保できる太陽電池パネルを提供することにある。   An object of the present invention is to provide a solar cell panel that can be disposed on adjacent roof surfaces with different inclination directions to increase the amount of power generation, and that can reliably ensure waterproof performance between the roof surfaces.

本発明の太陽電池パネルは、後述する実施形態での符号を用いて説明すれば、傾斜方向の異なる隣接した複数の屋根面１４〜１７に跨って配置されるとともに、前記複数の屋根面の交差角度に対応した角度をなす複数の受光面２１Ａを一体に備え、前記受光面は、一対設けられて、それぞれ多角形状に形成されており、各々の一辺部分が中枠２５を介して互いに接続され、前記一対の受光面のなす角度は、一対の屋根面が形成する凸状の交差角度に対応して設定されているていることを特徴とするものである。
また、本発明の太陽電池パネルは、傾斜方向の異なる隣接した複数の屋根面１４〜１７に跨って配置されるとともに、前記複数の屋根面の交差角度に対応した角度をなす複数の受光面２１Ａを一体に備え、前記受光面は、一対設けられて、それぞれ多角形状に形成されており、各々の一辺部分が中枠２５を介して互いに接続され、前記一対の受光面のなす角度は、一対の屋根面が形成する凹状の交差角度に対応して設定されるものであってもよい。 If it demonstrates using the code | symbol in embodiment mentioned later, while the solar cell panel of this invention is arrange | positioned ranging over the several adjacent roof surfaces 14-17 from which an inclination direction differs, cross | intersection of the said several roof surfaces A plurality of light receiving surfaces 21A having an angle corresponding to the angle are integrally provided, and a pair of the light receiving surfaces are provided, each of which is formed in a polygonal shape, and one side portion of each is connected to each other via an inner frame 25. The angle formed by the pair of light receiving surfaces is set corresponding to the convex intersection angle formed by the pair of roof surfaces.
Moreover, the solar cell panel of the present invention is disposed across a plurality of adjacent roof surfaces 14 to 17 having different inclination directions, and a plurality of light receiving surfaces 21A forming an angle corresponding to an intersection angle of the plurality of roof surfaces. The light receiving surfaces are provided in a pair and are formed in a polygonal shape, each side portion is connected to each other via the inner frame 25, and the angle formed by the pair of light receiving surfaces is a pair. It may be set corresponding to the concave intersection angle formed by the roof surface.

この発明によれば、屋根面に対応した複数の受光面を一体に備えた太陽電池パネルを、複数の屋根面に跨って配置するため、たとえば、下り棟を形成する一対の屋根面に跨って太陽電池パネルを配置する場合でいえば、下り棟には、従来のような太陽電池パネル同士の連結部が生じないから、笠木等を設けなくとも屋根の防水性能が十分に確保される。また、本発明の太陽電池パネルが屋根の下り棟等に配列されることで、屋根に隙間なく太陽電池パネルが配列されるから、大きな発電力が得られる。
また、一対の屋根面が形成する凸状の交差角度に対応して一対の受光面のなす角度を設定すれば、例えば、屋根の大棟や下り棟等に沿って太陽電池パネルが配置可能となる。
一方、一対の屋根面が形成する凹状の交差角度に対応して一対の受光面のなす角度を設定すれば、例えば、一対の屋根面が形成する谷等に沿って太陽電池パネルが配置可能となる。 According to this invention, in order to arrange the solar cell panel integrally provided with a plurality of light receiving surfaces corresponding to the roof surface across the plurality of roof surfaces, for example, straddle the pair of roof surfaces forming the down wing. In the case where the solar cell panels are arranged, since the connecting portion between the solar cell panels as in the conventional case does not occur in the descending ridge, the waterproof performance of the roof is sufficiently ensured without providing a headboard or the like. Moreover, since the solar cell panel of this invention is arranged in the down ridge etc. of a roof, since a solar cell panel is arranged without a clearance gap on a roof, a big electric power generation is obtained.
Also, if the angle formed by the pair of light receiving surfaces is set corresponding to the convex intersection angle formed by the pair of roof surfaces, for example, the solar cell panel can be arranged along the large ridge or the down ridge of the roof. Become.
On the other hand, if the angle formed by the pair of light receiving surfaces is set corresponding to the concave crossing angle formed by the pair of roof surfaces, for example, the solar cell panel can be arranged along a valley formed by the pair of roof surfaces. Become.

この際、本発明の太陽電池パネルでは、前記受光面を形成するパネル体と、当該パネル体を囲むフレームとを備え、このフレームの一辺を形成する枠材によって前記中枠が構成されていることが好ましい。

Is preferred.
According to such a configuration, each side of the frame surrounding each panel body constituting the pair of light receiving surfaces is connected to each other by the middle frame, so that rain can enter without providing a headboard or the like above the frame. It can be prevented, and the waterproof performance of the roof is sufficiently secured.

また、本発明の太陽電池パネルでは、前記一対の受光面のなす角度が前記中枠に沿った軸回りに調節可能に設けられていることが好ましい。
このような構成によれば、複数の受光面のなす角度を調節可能に設けたので、複数の屋根面の交差角度に応じて、複数の受光面のなす角度を調節することで、あらゆる屋根面の交差角度に対応できる。 In the solar cell panel of the present invention, it is preferable that an angle formed by the pair of light receiving surfaces is provided so as to be adjustable around an axis along the middle frame.
