| 1. A complex system of vegetation and solar cell in which a solar cell system and a plant group are installed together on
a roof surface of a same plane, wherein an average height of a light-receiving surface of a solar cell module from the roof
surface is greater than an average height of the plant group from the roof surface,
b is the average height of the surface of the solar cell module from the roof surface;
a is the average height of the plant group from the roof surface;
c is the distance from the plant group and the solar cell module that are adjacent; and
a, b and c satisfy the equation:
c≧b−a.
