SOLAR BATTERY MODULE INSTALLING STRUCTURE AND PHOTOVOLTAIC POWER GENERATOR

摘要

PROBLEM TO BE SOLVED: To suppress shade generated in a solar battery module as far as possible, and to increase power which can be used by photovoltaic power generation by ensuring high power generation efficiency.SOLUTION: In an installation structure of a solar battery module, solar battery modules 10 to which solar battery cell 11 are connected in series are arranged and attached in a vertical direction on a back surface side opposite to a traveling path of a sound insulation wall 600, and each solar battery module 10 is inclined so as to come close to the sound insulation wall 600 toward an upper side. An upper end side and a lower end side of the solar battery module 10 are respectively held by an upper holding portion 20 and a lower holding portion 30 fixed to the back surface side of the sound insulation wall 600. The upper holding portion 20 is formed to have outward projecting amount smaller than that of the lower holding portion 30. Shade generated on a light-receiving surface 12 of the solar battery module 10 by sunlight at the meridian height on the summer solstice, is set to be less than a regulation area in which the solar battery modules 10 can generate power, from an upper end of the light-receiving surface 12.
