1. A solar cell module comprising M cell groups each comprising N solar cells, with M being an integer of 3 or more, and N being an integer of 3 or more,
each of the solar cells being a three-terminal tandem solar cell comprising: a first photoelectric converter; a second photoelectric converter; first and second cell terminals for the first photoelectric converter; and the first cell terminal and a third cell terminal for the second photoelectric converter,
the N first photoelectric converters being connected in series in the cell group, wherein
when the first cell terminal at one end of the first photoelectric converters connected in series in a first one of the cell groups is at a reference potential,
the second cell terminal at another end of the first photoelectric converters connected in series in an m-th one of the cell groups is connected to the first cell terminal at one end of the first photoelectric converters connected in series in another m+2-th or later one of the cell groups, with m being an integer from 1 to M,
the N third cell terminals in the m-th cell group are respectively connected to the N first cell terminals in an m+1-th one of the cell groups, and
an absolute value of a potential difference between the second cell terminal at the another end in the m-th cell group and the first cell terminal at the one end in the another cell group, the cell terminals being connected to each other, is equal to or less than 10% of an absolute value of a potential difference between the first cell terminal at the one end in the m-th cell group and the second cell terminal at the another end in the m-th cell group when the second cell terminal at the another end in the m-th cell group and the first cell terminal at the one end in the another cell group remain not connected to each other.
