Description
本発明は、屋根瓦に係り特に複数の太陽光発電素子を配列し並列接続してなる発電ユニットを装着した瓦に関する。 The present invention relates to a tile fitted with power generation units, especially ing by arranging a plurality of photovoltaic elements connected in parallel relates to a roof tile.
従来から，太陽光発電システムに用いるための瓦が種々提案されている。
実公昭６３−１１７４７号公報によれば、瓦の表面上、または瓦表面に設けた凹部内に発電ユニットを接着した瓦を、屋根に敷設することにより太陽光発電システムを構成することができる。
Conventionally, various roof tiles for use in solar power generation systems have been proposed.
According to Japanese Utility Model Publication No. 63-11747, a solar power generation system can be configured by laying a roof with a power generation unit bonded on the surface of the roof tile or in a recess provided on the roof surface.
しかしながら、夏冬の温度差、昼夜の温度差により膨張係数の異なる瓦と発電ユニットの基板が、膨張収縮を繰り返すため数年で接着力が低下し発電ユニットの基板との接着力が低下し隅部から剥離してくる欠点があった。
特に瓦の表面上に施された釉薬層は耐水効果を高めているが、発電ユニットを接着する場合、瓦表面のガラス質である釉薬層と接着材との馴染みが悪く接着強度が低下していた。
However, the roof tiles and power generation unit boards, which have different expansion coefficients due to the temperature difference between summer and winter, and the temperature difference between day and night, repeatedly expand and contract. There was a defect of peeling from the part.
In particular, the glaze layer applied on the surface of the roof tiles increases the water resistance, but when the power generation unit is bonded, the adhesion between the glass layer glaze layer on the roof surface and the adhesive is poor and the adhesive strength is reduced. It was.
また、実開昭５９−４２２１６号公報には、瓦の上端部表面側に太陽電池群の引き出し線が接続された少なくとも２個のリード端子が突出して設けられ、瓦の下部端裏面側に、隣接する瓦の上部表面側に有る前記リード端子に弾性接触する受けリード端子が埋設された太陽電池搭載瓦が提案されている。 Further, in Japanese Utility Model Publication No. 59-42216, at least two lead terminals, to which the lead wires of the solar cell group are connected, are provided to protrude on the surface side of the upper end of the roof tile, There has been proposed a solar cell-mounted tile in which receiving lead terminals that are in elastic contact with the lead terminals on the upper surface side of adjacent tiles are embedded.
しかしながら、瓦の上端部表面側のリード端子までの引き出し線が瓦表面と同一平面に成らず防水処理が煩雑であり、また、引き出し線が上部瓦との重なり部で、上部瓦の荷重を受けて損傷することがあった。
また、上下の瓦の重なり部でそれぞれのリード端子が弾性接触で導通されているが、長期間の振動による瓦の移動による弾性力の低下や、長期間に亘り風雨に曝される間に弾性接触部が酸化あるいは硫化されて、接触抵抗が増大し発電効率の低下をもたらしていた。
However, the lead wires to the lead terminals on the top surface of the roof tile are not flush with the roof surface, and waterproofing is complicated, and the lead wires are overlapped with the top roof and receive the load from the top roof. Could be damaged.
In addition, each lead terminal is electrically connected by elastic contact at the overlapping part of the upper and lower roof tiles, but the elasticity decreases due to the movement of the roof tile due to long-term vibration, and during prolonged exposure to wind and rain. The contact portion is oxidized or sulfided to increase the contact resistance, resulting in a decrease in power generation efficiency.
また、特開２０００−３５２１５５号公報には瓦本体の下面に端子ボックスを備えた瓦が提案されているが、端子ボックス部が厚くなり瓦下面の野地板との接触面積が少なくなるので荷重に耐える強度を増すために、全体的に厚くて重い瓦となっていた。 Japanese Laid-Open Patent Publication No. 2000-352155 proposes a tile having a terminal box on the lower surface of the tile body. However, the terminal box becomes thicker and the contact area with the base plate on the lower surface of the tile is reduced. In order to increase the strength to withstand, the roof was thick and heavy overall.
