Title:
Photovoltaic power generation apparatus
Document Type and Number:
Japanese Patent JP6119099
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve energy conversion efficiency for the full year of a photovoltaic power generation device.SOLUTION: A photovoltaic power generation device comprises plural photovoltaic members provided on a mounting object surface with an inclination angle α to a lower part of a vertical plane, and having a light-receiving surface for receiving sunlight. The device has: a first photovoltaic member whose inclination angle θ1 of a light receiving face to a lower part of the vertical plane is set to an arbitrary angle within a range (θm<θ1≤θs) larger than a vernal or autumnal equinox elevation angle θm and equal to or smaller than a summer solstice elevation angle θs, when an elevation angle to a south of a sun during a meridian time of a summer solstice is designated as a summer solstice elevation angle θs, an elevation angle to a south of a sun during a meridian time of a winter solstice is designated as a winter solstice elevation angle θw, and an elevation angle to a south of a sun during a meridian time of a vernal or autumnal equinox is designated as a vernal or autumnal equinox elevation angle θm; and a second photovoltaic member whose inclination angle θ2 of a light receiving face to a lower part of the vertical plane is set to an arbitrary angle within a range (θw≤θ2<θm) equal to or larger than the winter solstice elevation angle θw and smaller than the vernal or autumnal equinox elevation angle θm.
