人口増加や生活水準向上に対応する社会インフラ整備への動きが新興国や発展途上国で活発になっている。一方,安心安全な社会を未来へ継承するために,低炭素社会実現に向けて世界各国で様々な取組みが実施されている。このような状況をふまえ,二酸化炭素排出量が多い火力発電や事故リスクの大きい原子力発電への大幅なエネルギー依存は避け,太陽光や太陽熱等の再生可能エネルギーの利用拡大がさらに重要になると予想されている。
筆者らは,太陽エネルギーの効率的な利用を目的として,日射遮蔽,発電,熱回収の3つの機能を同時に可能にした熱回収型太陽電池ルーバーを試作し屋上実験を実施した。実験の結果、熱回収型太陽電池ルーバーの最大発電量は100W/m2程度で,最大集熱量は200W/m2前後であることがわかりました。また、実験結果に基づき夏季と冬季の発電量と出口水温を気象状況から予測できる計算式を示しました。

Many movements for equipped infrastructure to come up with several answers to the population explosion and an improvement in the standard of living have been active in merging nation and developing country.
Whereas, to be succeeded to reliable and safety society for the future, many measures for low carbon society were conducted all over the world. In the light of social situation, the human have to avoid extensive dependence on thermal power generation which has many carbon dioxide emissions and nuclear electric power generation which have many tremendous risks created by accidents. In the future, to make good use of the renewable energy (such as sunlight and solar energy) will be increasingly important.
The purpose of this study is to make efficient use of solar energy. Authors conducted outdoor experiment using hybrid solar louver which possessed solar shading, generation of electricity and thermal recovery was produced. Our major finding though this study is introduced as below:
1)The maximum volume in generation of electricity is approximately 100W/m2
The maximum volume in thermal recovery is about 200W/m2.
2)Authors can predict generation of electricity and thermal recovery with formulas produced by multiple regression analysis.
