PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system in which reflection light is efficiently entered on the reverse side of a solar cell module.SOLUTION: When, where the length of a first solar cell array 3A and a second solar cell array 3B aslant at an angle &thetas; is L, the distance from a solar cell module of the first solar cell array and a solar cell module of the second solar cell array to an installation surface 2 is a, the meridian height at winter solstice is α°, and the meridian height at summer solstice is &bgr;°, an interval between the first solar cell array and the second solar cell array is Lsin&thetas;*tanγ+Lsin&thetas;/tan(α+γ) and an angle γ isγ≤90°-&bgr;, a diffusion reflection member is disposed between a position P1 which is (Lsin&thetas;+acosγ)tanγ+(Lsin&thetas;+acosγ)/tan(&bgr;+γ) to a one direction side from a position P on the installation surface of the first solar cell array intersecting a perpendicular line in the vertical direction from an end on the second solar cell array side and a position P2 which is (Lsin&thetas;+acosγ)tanγ+(Lsin&thetas;+acosγ)/tan(α+γ) to the one direction side from the position P. |
