To make a pilot of an aircraft in a landing approach be less likely to be dazzled by a reflection light of sunlight.SOLUTION: A photovoltaic power generation system comprises one or more solar battery modules. Each solar battery module has a light-receiving surface, including a solar battery cell and a translucent member at the light-receiving surface side. A first virtual line is extended along a path on which an aircraft flies toward a first point between target point marks on a runway and located along a virtual vertical plane passing through runway center line marks on the runway. A virtual right circular cone has a second point on the first virtual line as a vertex and has a vertex angle of 50 degrees with a center line extended along the first virtual line. The translucent member has such a configuration that an estimation irradiance of reflection light entering retinas of eyeballs located at the second point depending on reflection of sunlight in a reflection region located in the virtual right circular cone of one or more solar battery modules, is set to be less than a critical irradiance Et calculated by an expression of Et=0.359/ω1.77 that uses a visual angle ω in the eyeballs regarding the reflection region.SELECTED DRAWING: Figure 1

    【課題】着陸態勢にある航空機の操縦士が太陽光の反射光に眩惑され難くする。【解決手段】太陽光発電システムは、1つ以上の太陽電池モジュールを備える。各太陽電池モジュールは、受光面を有し、太陽電池セルと受光面側の透光性部材とを含む。第1仮想線は、滑走路の目標点標識の間の第1点に向かって航空機が飛行する経路に沿って延び、且つ滑走路の滑走路中心線標識を通る仮想の鉛直面に沿って位置している。仮想直円錐は、第1仮想線上の第2点を頂点として有し且つ第1仮想線に沿って延びている中心線と50度の頂角とを有する。透光性部材は、1つ以上の太陽電池モジュールのうちの仮想直円錐内に位置している反射領域における太陽光の反射に応じて第2点に位置している眼球の網膜に入射する反射光の推定放射照度を、反射領域についての眼球における視角ωを用いたEt=0.359/ω1.77の式で算出される臨界放射照度Et未満にする形態を有する。【選択図】図1
