<p>PROBLEM TO BE SOLVED: To provide a photovoltaic power generation device capable of obtaining a sufficient light condensation rate by using a reflection sheet.SOLUTION: In a photovoltaic power generation device in which solar cells having substantially rectangular light reception surfaces inclined upward to the south are arranged in two or more arrays in the south-north direction, a first reflection sheet between north end sides of the solar cells and an installation ground surface therebelow, and a second reflection sheet between south end sides of the solar cells and an installation ground surface therebelow are spread, and insulation surface light reflection constitution is provided on an inter-array installation surface between a ground line of the first reflection sheet and a ground line of the second reflection sheet. Alternatively, a reflection sheet is stuck on a curved reflection surface provided between a south end side of one solar cell panel array and a north end side of a south adjacent solar cell panel array. Here, the light condensation rate can be enhanced more by spreading a fourth reflection sheet above a north end side of the photovoltaic power generation device in the northernmost array and a fifth reflection sheet between adjacent arrays of solar cells at an east end or west end.</p> |
