wherein a portion of the first solar cell that includes the upper electrode and the second lateral side thereof is overlapped in the third direction by a portion of a first adjacent one of the intermediate solar cells that includes the lower electrode and the first lateral side thereof, such that the first solar cell has a first overlapped portion,
wherein a portion of the second solar cell that includes the lower electrode and the first lateral side thereof overlaps in the third direction with a portion of a second adjacent one of the intermediate solar cells that includes the upper electrode and the second lateral side thereof, such that the second solar cell has a second overlapped portion and the second adjacent one of the intermediate solar cells has a third overlapped portion,
wherein the solar cell panel further comprises a first connecting member connecting the upper electrode of the first solar cell to the lower electrode of the first adjacent one of the intermediate solar cells and a second connecting member connecting the upper electrode of the second adjacent one of the intermediate solar cells to the lower electrode of the second solar cell,
wherein each of a width of the first overlapped portion of the first solar cell in the second direction, a width of the third overlapped portion of the second adjacent one of the intermediate solar cells, the first spacing distance, the second spacing distance, the third spacing distance, the first width of the first solar cell, the second width of the second solar cell, and the third width of the one or more intermediate solar cells are all configured so that when the first solar cell, the second solar cell, and the one or more intermediate solar cells are connected to one another via the first and second connecting members, a photoelectric conversion area of each of the plurality of the solar cells is the same and a current flow of each of the plurality of the solar cells is the same, and wherein the upper electrode of the first solar cell is a first bus bar electrode that is located at the second lateral side of the first solar cell, the second lateral side of the first solar cell being a cut surface, and wherein the second solar cell includes a second bus bar electrode that is located at the second lateral side of the second solar cell and on the upper surface thereof, the second lateral side of the second solar cell being a non-cut surface.
