Description

本発明は、隣り合う２枚の太陽電池パネルを電気的に接続する太陽電池パネル接続構造、及び、そのような太陽電池パネル接続構造を備え、配列された２枚以上の太陽電池パネルにおいて隣り合うもの同士が電気的に接続された太陽電池アレイに関する。   The present invention includes a solar cell panel connection structure that electrically connects two adjacent solar cell panels, and such a solar cell panel connection structure, and is adjacent in two or more solar cell panels arranged. The present invention relates to a solar cell array in which things are electrically connected.

地球環境問題に対する関心の高まりを受けて、温室効果ガスの削減等に効果が期待される太陽光発電が注目されている。近年では、太陽光発電の利用が一般家庭にまで及んでおり、例えば住宅等の建築物の屋根に太陽電池パネルを設置する等といったことが広く行われるようになっている。   In response to growing interest in global environmental problems, solar power generation is expected to be effective in reducing greenhouse gases. In recent years, the use of solar power generation has been extended to ordinary households, and for example, solar cell panels have been widely used on the roofs of buildings such as houses.

ここで、多くの場合、太陽光発電では、２枚以上の太陽電池パネルが配列されて使われる。これら２枚以上の太陽電池パネルは、隣り合うもの同士が電気的に接続されて太陽電池アレイを構成している。隣り合う２枚の太陽電池パネルを電気的に接続する構造としては、これら２枚の太陽電池パネルを接続ケーブルで繋ぐことが考えられる。しかしながら、建築物の屋根等といった作業性があまり良くない場所でこのような接続ケーブルを配線する作業は、なるべく少なくしたいところである。   Here, in many cases, in solar power generation, two or more solar battery panels are arranged and used. Adjacent ones of these two or more solar cell panels are electrically connected to form a solar cell array. As a structure for electrically connecting two adjacent solar cell panels, it is conceivable to connect these two solar cell panels with a connection cable. However, it is desirable to reduce the work of wiring such a connection cable in a place where workability is not so good, such as a roof of a building.

そこで、隣り合う２枚の太陽電池パネルを、各太陽電池パネルに取り付けた端子台を介して電気的に接続する太陽電池パネル接続構造が提案されている（例えば、特許文献１参照。）。この特許文献１に記載の太陽電池パネル接続構造では、各端子台には太陽電池パネルに接続するための端子が設けられ、太陽電池パネルの端縁から端子を露出させて端子台が取り付けられている。そして、２枚の太陽電池パネルを隣接配置した際に、一方の太陽電池パネルの端子台が、他方の太陽電池パネルの端子台と重なるように構成されている。このような端子台の重なりにより、２枚の太陽電池パネルそれぞれの端子台の端子が互いに接続されて、これら２枚の太陽電池パネルが電気的に接続される。   Then, the solar cell panel connection structure which electrically connects two adjacent solar cell panels via the terminal block attached to each solar cell panel is proposed (for example, refer patent document 1). In the solar cell panel connection structure described in Patent Document 1, each terminal block is provided with a terminal for connecting to the solar cell panel, and the terminal block is attached by exposing the terminal from the edge of the solar cell panel. Yes. And when two solar cell panels are adjacently arranged, the terminal block of one solar cell panel is comprised so that it may overlap with the terminal block of the other solar cell panel. Due to such overlapping of the terminal blocks, the terminals of the respective terminal blocks of the two solar cell panels are connected to each other, and the two solar cell panels are electrically connected.

このような太陽電池パネル接続構造によれば、上記の端子台を重ねつつ太陽電池パネルを設置することで、太陽電池パネルの電気的な接続が行われる。これにより、２枚以上の太陽電池パネルで太陽電池アレイを構成する際における接続ケーブルの配線作業を減らして作業者の負担を軽減することができる。   According to such a solar cell panel connection structure, the solar cell panel is electrically connected by installing the solar cell panel while overlapping the terminal blocks. Thereby, the wiring operation | work of the connection cable at the time of comprising a solar cell array with two or more solar cell panels can be reduced, and a worker's burden can be eased.

ここで、太陽電池アレイに対するメンテナンスにおいて、例えば劣化した太陽電池パネルの交換が行われることがある。この交換時には、既設の太陽電池パネルが取り外される。また、太陽電池アレイの設置作業自体においても、一旦設置した太陽電池パネルが何等かの理由により取り外されることがある。このとき、上述した太陽電池パネル接続構造を採用した太陽電池アレイでは、取外し対象の太陽電池パネルの端子台に他の太陽電池パネルの端子台が重なっていることがあり、その太陽電池パネルも一緒に取り外さなければならない場合がある。更には、その一緒に取り外す太陽電池パネルの端子台に更に別の太陽電池パネルの端子台が重なっていると、その太陽電池パネルも一緒に取り外す必要が出て来る。そのため、既設の太陽電池パネルを取り外す際には、その太陽電池パネルよりも前に端子台を重ねて設置された太陽電池パネルを全て外す必要がある。このように、上記の太陽電池パネル接続構造は、太陽電池パネルの設置作業について良好な作業性が得られる反面、既設の太陽電池パネルの取外し作業において改善の余地を残したものとなっている。   Here, in the maintenance for the solar cell array, for example, a deteriorated solar cell panel may be replaced. At the time of this replacement, the existing solar cell panel is removed. Also, in the solar cell array installation work itself, the solar cell panel once installed may be removed for some reason. At this time, in the solar cell array adopting the solar cell panel connection structure described above, the terminal block of another solar cell panel may overlap the terminal block of the solar cell panel to be removed, and the solar cell panel is also joined together. You may have to remove it. Furthermore, when the terminal block of another solar cell panel overlaps with the terminal block of the solar cell panel to be removed together, the solar cell panel needs to be removed together. Therefore, when removing an existing solar cell panel, it is necessary to remove all of the solar cell panels installed with the terminal block placed in front of the solar cell panel. As described above, the solar cell panel connection structure described above provides good workability for the installation work of the solar cell panel, but leaves room for improvement in the removal work of the existing solar cell panel.
