これら第1電極端子21と第2電極端子22とは、互いに反対方向に(すなわち電池1a-1cの配列方向に直交する方向に)突出し、かつ、互いに反対面を向くように形成されている。
把持部材15Bは、第1電極端子21と第2電極端子22とを一直線上に並べて交互に配置させる固定部16Bと、固定部16Bに対向配置させて第1電極端子21及び前記第2電極端子22を挟持する押え部17Bをそれぞれ有している。
固定部16Aの表面16sには、電池1a-1cの端部10,11を載置させる第1嵌合凹所25及び第2嵌合凹所26が形成されている。
第1嵌合凹所25と第2嵌合凹所26とは、固定部16Aの短手方向の一端16a側に開口するように、かつ、固定部16Aの長手方向に交互に形成されている。
これらの第1嵌合凹所25及び第2嵌合凹所26の深さは、電池1a-1cの厚さ寸法よりも小さく形成されている。
固定部16Aの第1嵌合凹所25及び第2嵌合凹所26が形成された表面16sには、一組の第1嵌合凹所25及び第2嵌合凹所26毎に、これら一組の第1嵌合凹所25及び第2嵌合凹所26同士の間に亘って連続的に導電材Eが配されている。
固定部16A及び押え部17Aの長手方向には、これらの間に電池1a-1cを挟み込んだ際に、図4に示すように、第2電極端子22及び導電材Eを貫通する位置に貫通孔30が形成されている。貫通孔30にはビス等の緊締部材40が挿通できるようになっている。
固定部16B及び押え部17Bの長手方向には、これらの間に1a-1cを挟み込んだ際に、図4に示すように、第2電極端子22及び導電材Eを貫通する位置に貫通孔30が形成されている。貫通孔30にはビス等の緊締部材40が挿通できるようになっている。
押え部17A,17Bは、合成樹脂材料等の絶縁材料を用いて固定部16Aと同じ外形で形成されている。
まず、図3に示すように、固定部16Aと固定部16Bとに電池1a-1cを嵌合させ得る間隔を空けて固定部16A,16Bを配置する。
固定部16Aの第1嵌合凹所25には、電池1a,1cの第1電極端子21を底面25tに対向させて端部10を嵌合させる。そうすると、電池1a,1cの端部11が、第2電極端子22を底面26tと同じ向にして固定部16Bの第2嵌合凹所26に嵌合する。
次に、端部10,11を間に挟んだ状態で、押え部17Aを固定部16Aの表面16s上に配置する。そして、貫通孔30に緊締部材40を挿通させて固定部16Aと押え部17Aとを緊締する。
同様にして押え部17Bを固定部16Bの表面16s上に配置する。そして、貫通孔30に緊締部材40を挿通させて固定部16Bと押え部17Bとを緊締する。
この状態で、電池1a-1cを把持した取付具2を建物の壁又は屋根等の取付対象に接着テープ又はビス等で取り付ける。
また、太陽電池の取付構造X1は、取付具2の構造が極めてシンプルであるため、外観的に優れているという効果を奏する。
また、切欠き18,19は線対称の位置に形成されていないものが1つ以上あればよく、その余はどのような位置又は形状でいくつ形成してもよい。ただし、同一の形状の2つの把持部材15A,15Bを一組として利用できるようにすることを考慮すると、切欠き18,19は回転対称に形成されていることが望ましい。
また、把持部材15Aの残りの第1嵌合凹所25と端子45との間に導電材Eを連続して設ける。
また、把持部材15Bにおいては、押え部17Bの端部に端子45を設け、電池1aの第2電極端子22に対向する押え部17Bの板面に導電材Eを配する。更に、電池1bの第1電極端子21と電池1cの第2電極端子22とに対向する押え部17Bの板面に導電材Eを連続的に配する。
なお、上記各実施形態において、取付具2に取り付けられる電池1a-1cは、それぞれ1つの発電素子により構成されているが、本発明はかかる構成に限定されない。すなわち、本発明に適用される電池は、第1電極端子21と第2電極端子とを22とが、それぞれ一辺側の端部と対辺側の端部とに形成されたものであれば、複数の発電素子を集合させてモジュール化させたものであってもよい。
