Abstract

The power generation module group 1 includes a sheet 10 and power generation panels 21 to 24. First lines L1 and L1′ are present between the panels 21 and 22 adjacent to each other in the lateral direction, the first lines crossing neither the panels 21 nor 22 and coming in contact with both the panels 21 and 22. The second line L2 is present on the bottom side of the panel 21 and on the bottom side of the panel 22, crosses neither the panels 21 nor 22 and is parallel in the lateral direction. An angle θ1 that is the largest angle on the panel 22 side of angles formed by the second line L2 and the first lines L1 and L1′ is an acute angle. The panels 23 and 24 are disposed in line symmetry with the panels 21 and 22, respectively, with respect to the lateral direction.

First claim

the plurality of power generation panels include a first power generation panel, a second power generation panel, a third power generation panel, and a fourth power generation panel,
the first power generation panel and the second power generation panel are disposed adjacent to each other in a lateral direction,

the third power generation panel and the fourth power generation panel are disposed adjacent to each other in the lateral direction,
the third power generation panel is disposed adjacent to the first power generation panel in a longitudinal direction and is in line symmetry with the first power generation panel with respect to the lateral direction,
the fourth power generation panel is disposed adjacent to the second power generation panel in the longitudinal direction and is in line symmetry with the second power generation panel with respect to the lateral direction,
a plurality of first straight lines can be drawn from an edge of the first power generation panel to an edge of the second power generation panel such that the plurality of first straight lines do not cross an interior of the first power generation panel nor an interior of the second power generation panel, even if the plurality of first straight lines were extended at both ends;
a second straight line can be drawn in the lateral direction, in a gap between the first power generation panel and the third power generation panel and a gap between the second power generation panel and the fourth power generation panel;
the plurality of first straight lines and the second straight line intersect to form a plurality of first angles on a side of the first power generation panel facing the second power generation panel, wherein an angle of a largest angle among the plurality of first angles is an acute angle;
a plurality of third straight lines can be drawn from an edge of the third power generation panel to an edge of the fourth power generation panel, such that the plurality of third straight lines do not cross the interior of the third power generation panel nor the interior of the fourth power generation panel, even if the plurality of third straight lines were extended at both ends;
the plurality of third straight lines and the second straight line intersect to form a plurality of second angles on a side of the third power generation panel facing the fourth power generation panel, wherein an angle of a largest angle among the plurality of second angles is an acute angle;
on the flexible sheet, a length of each portion of the flexible sheet coming in contact with each side of the plurality of power generation panels is shorter than a length of each side of the plurality of power generation panels, each portion of the flexible sheet being located between any two of the plurality of power generation panels which are adjacent to each other;
the largest angle among the plurality of first angles is larger than a smallest angle among internal angles of the plurality of power generation panels;
