Description

本発明は、太陽電池モジュール固定装置及びその形成方法に関するものである。   The present invention relates to a solar cell module fixing device and a method for forming the same.

近年、地球環境問題への関心の高まりとともに、自然エネルギーを利用した新エネルギー技術のひとつとして、太陽光発電システムが注目され、その実用化が加速されてきている。太陽光発電システムは、その構成要素である太陽電池により太陽光エネルギーを電力に変換して利用するものである。   In recent years, with increasing interest in global environmental problems, solar power generation systems have attracted attention as one of the new energy technologies using natural energy, and their practical application has been accelerated. A solar power generation system converts solar energy into electric power and uses it by a solar cell which is a constituent element thereof.

本出願人は、家屋等の屋根と一体的に多数の太陽電池モジュールを取りつける場合、係止用開口部を有した直線状のレール溝を設けた基台と該基台上に配置された前記太陽電池モジュールの周縁部を押圧して当接固定するための押圧部材と前記レール溝に沿って移動可能でかつ前記係止用開口部に係合させながら前記押圧部材を固定するための締結部材とを備えてなる屋根固定装置を提案している。   In the case of attaching a large number of solar cell modules integrally with a roof such as a house, the applicant of the present application has a base provided with a linear rail groove having a locking opening and the base disposed on the base. A pressing member for pressing and fixing the peripheral edge of the solar cell module and a fastening member that is movable along the rail groove and that fixes the pressing member while being engaged with the locking opening. A roof fixing device is proposed.

これは、図４（ｂ）に示すように、屋根上に固定装置Ｋ（Ｋ１〜Ｋ８）を多数配置して太陽電池モジュールＰ（Ｐ１〜Ｐ２）を屋根上に配する場合、図４（ａ）に示すように、屋根用固定装置Ｋの基台１上に配置された押圧部材４をボルト等で締め付けることにより、前記太陽電池モジュールＰのフレーム部材１６Ａ、１６Ｂを押圧して当接固定されるようにし、前記基台１のレール溝に沿って前記押圧部材を移動可能とすることで屋根用固定装置Ｋの設置位置の許容範囲が大きくなり、施工性が向上し、また、縦桟や横桟を不要として部材の削減を図るものである（特許文献１を参照）。   As shown in FIG. 4B, when a large number of fixing devices K (K1 to K8) are arranged on the roof and the solar cell modules P (P1 to P2) are arranged on the roof, as shown in FIG. ), The frame member 16A, 16B of the solar cell module P is pressed and fixed by tightening the pressing member 4 arranged on the base 1 of the roof fixing device K with a bolt or the like. In this way, by allowing the pressing member to move along the rail groove of the base 1, the allowable range of the installation position of the roof fixing device K is increased, the workability is improved, It is intended to reduce the number of members by eliminating the need for a horizontal rail (see Patent Document 1).

また、このような固定装置において、一つの係止部で２枚以上の太陽電池モジュールを系止すると同時に前記押圧部材で、太陽電池モジュールのフレームに施されているアルマイト皮膜やクリア塗装皮膜を破ることにより、屋根傾斜方向の太陽電池モジュールどうしを電気的に導通させることを提案した。
特願２００１−２９４０５１号 Further, in such a fixing device, two or more solar cell modules are stopped by one locking portion, and at the same time, the pressing member breaks an alumite film or a clear coating film applied to the frame of the solar cell module. Therefore, it was proposed that the solar cell modules in the roof inclination direction be electrically connected to each other.
Japanese Patent Application No. 2001-294051

しかしながら、図６に示すように、太陽電池モジュールのフレーム部材１６Ａ、１６Ｂに施されているアルマイト皮膜やクリア塗装皮膜を破るために、押圧部材に鋭凸状の導通部４ｃが形成されており、当該導通部４ｃでフレーム部材１６Ａ、１６Ｂを押圧する構造上、フレーム部材１６Ａ、１６Ｂの押えが点接触となっている。このような状態で、太陽電池モジュールに一定以上の風荷重が掛かった場合、実験によれば風荷重が太陽電池モジュールＰを持ち上げる方向に作用すると、太陽電池モジュール本体１５を構成しているガラスが撓み、太陽電池モジュールのフレーム部材１６Ａ、１６Ｂが撓む。この時押圧部材４が導通部４ｃで点接触で押圧して当接固定しているため、フレーム部材が押圧部材から抜け出す方向に力が作用し、フレーム部材の撓みが増大しフレーム部材がガラス面から外れてしまうといった不具合の恐れがあり、このため、太陽電池モジュールを構成するフレーム部材の強度を上げねばならない。これは、大型化や重量増といった問題に繋がる。   However, as shown in FIG. 6, in order to break the alumite film and the clear paint film applied to the frame members 16A and 16B of the solar cell module, a sharp convex conductive portion 4c is formed on the pressing member, Due to the structure in which the frame members 16A and 16B are pressed by the conductive portion 4c, the pressers of the frame members 16A and 16B are point contacts. In such a state, when a wind load of a certain level or more is applied to the solar cell module, according to an experiment, when the wind load acts in the direction of lifting the solar cell module P, the glass constituting the solar cell module body 15 is The frame members 16A and 16B of the solar cell module are bent. At this time, since the pressing member 4 is pressed and fixed by point contact at the conducting portion 4c, a force acts in a direction in which the frame member comes out of the pressing member, and the deflection of the frame member increases, so that the frame member becomes a glass surface. Therefore, the strength of the frame member constituting the solar cell module must be increased. This leads to problems such as an increase in size and weight.

また、太陽電池モジュールのフレームに施されているアルマイト皮膜やクリア塗装皮膜を破るために、押圧部材に導通部４ｃが形成されており、当該導通部４ｃでフレーム部材１６を上から押圧するため、雨水などが当該押圧部に溜まりやすく、アルマイト皮膜やクリア塗装皮膜を破った部分に滞留する恐れがあり、腐食の進行の懸念があった。   Further, in order to break the alumite film or clear paint film applied to the frame of the solar cell module, the conduction member 4c is formed on the pressing member, and the frame member 16 is pressed from above by the conduction member 4c. Rain water or the like tends to accumulate in the pressing portion and may stay in a portion where the alumite film or clear coating film has been broken.

そこで、本発明は上述の諸事情に鑑みてなされたものであり、荷重に対し、太陽電池モジュールのフレーム強度を上げることなく強固に固定すると共に、太陽電池モジュール間の電気的導通を確実かつ簡便にできる太陽電池モジュール固定装置及びその形成方法を提案することを目的とする。   Therefore, the present invention has been made in view of the above-described circumstances, and is firmly fixed to a load without increasing the frame strength of the solar cell module, and the electrical continuity between the solar cell modules is surely and simply. It aims at proposing the solar cell module fixing device which can be made, and its formation method.

を用いて前記第１の押圧部材に締着することによって、前記太陽電池モジュールを前記第１の押圧部材とともに挟持し、前記太陽電池モジュールと前記第２の押圧部材とを導通させる導通工程と、を備えるものである。 The method for forming a solar cell module fixing device according to the present invention includes a base provided with two linear rail grooves having locking openings at both ends, and a first pressing member positioned above the base. Bolts and nuts for disposing a solar cell module therebetween , engaging with the locking opening at a predetermined position in the linear direction of the rail groove, and fastening the base and the first pressing member using the first fastening member consisting of a fixed step of fixing the periphery of the solar cell module, the second pressing member made of a conductive material pressed from the lower side of the solar cell module, wherein The solar cell module is disposed between the two rail grooves of the base and fastened to the first pressing member using a second fastening member made of a bolt and a nut , whereby the solar cell module is placed in the first base. sandwiched with the pressing member, And conducting step of conducting a serial solar cell module and said second pressing member is one comprising a.

Even when installed on the roofing material provided, the solar cell module can be easily and stably installed on the roof with good workability without using any long member. It becomes possible to make the appearance of the installed state good.

また、太陽電池モジュールに想定以上の風荷重が掛かり、風荷重が太陽電池モジュールを持ち上げる方向に作用した場合でも、上側の第１の押圧部材で太陽電池モジュールを強く押さえ込むことができるので、フレームの強度を上げることなくフレームの撓みを最小限に押さえることができる。   Further, even when a wind load more than expected is applied to the solar cell module and the wind load acts in the direction of lifting the solar cell module, the solar cell module can be strongly pressed by the upper first pressing member. It is possible to minimize the bending of the frame without increasing the strength.

さらに、下側の第２の押圧部材に、太陽電池モジュールの周辺部との導通部を設けることができるので、太陽電池モジュールどうしを電気的に導通させても雨水等の影響による腐食の進行を抑制することができる。   Furthermore, since the lower second pressing member can be provided with a conductive portion with the peripheral portion of the solar cell module, even if the solar cell modules are electrically connected to each other, the progress of corrosion due to the influence of rainwater or the like is prevented. Can be suppressed.

Further, as shown in FIG. 1 (a), at least one or more rail grooves 2 are linearly provided at the left and right end portions 1a of the base 1, and the central portion 1b of the base 1 is a groove (or a recess). The groove (or recess) is provided with a plurality of through holes which are nail holes 1c for fixing to a roof material described later. As shown in the figure, it is desirable that the rail groove 2 has two structures because the structure is simple and the pressing member 4 can be firmly attached.

また、レール溝２はその最上部に溝幅が急に狭くなった係止用開口部３が形成されているが、必ずしもレール溝２の最上部でなくともよく、溝幅が狭く押圧部材４を固定するためのボルト６の頭部６ａを係合させることができればよく、その場所は特定されるものではない。また、第１の押圧部材４と第２の押圧部材５はこれらで押圧する部材より硬く例えばステンレス等の導電性を有し強度的にも優れた金属材料（導電性材料）から構成され
