PROBLEM TO BE SOLVED: To irradiate an entire photovoltaic power generation panel installed at a building such as a general residential house with sun light.SOLUTION: The installation structure of a photovoltaic power generation panel 1 includes: a photovoltaic power generation panel 1 installed by being vertically erected at a window of a building H such as a general residential house; a first mirror 2, provided below the photovoltaic power generation panel 1, for reflecting sun light L upward; and a second mirror 3 for reflecting the sun light L reflected by the first mirror 2 toward the photovoltaic power generation panel 1. The sun light L is reflected by the first mirror 2 or the first mirror 2 and the second mirror 3 and is irradiated on a surface of the photovoltaic power generation panel 1 where a shadow is generated by a roof R of the building H. |
