Abstract
Description
太陽光発電システムのソーラーパネルユニットは、太陽光をソーラーパネルの平面に直接到逹させ、ソーラーパネルを直接照光させる直下方式と、ソーラーパネルに反射鏡または集光レンズなどを活用する集光方式とに分けられる。建物屋上や地上に設ける太陽光発電施設は、直下方式が主に適用されるが、それは、レンズや鏡を利用する集光方式に比べて効率が落ちる。そのような直下方式の欠点を補う集光方式は、複雑な光学構造、及びそれを支持する構造体を含むことになる。従って、それら従来のソーラーパネルは、製造コスト高くて、また高集光(high condensation of light)によるソーラーパネルの寿命短縮を避けることができない。
本発明が解決しようとする課題は、また、熱衝撃からソーラーパネルを効果的に保護し、ソーラーパネルの寿命を延ばすことができる太陽光発電ユニット、及びそれを適用する発電システムを含むことである

多数太陽光発電ユニットの発電部が一つに集積されている多重発電部と、
前記多数太陽光発電ユニットの輸送部が一つに集積されている多重輸送部と、
