Claim Text:
1. A bifacial solar cell module comprising: a solar cell panel including a plurality of bifacial solar cells arranged in a column and a row; a front substrate on a front side of the plurality of bifacial solar cells; a back substrate on a back side of the plurality of bifacial solar cells; a first protective layer between the plurality of bifacial solar cells and the front substrate; a second protective layer between the plurality of bifacial solar cells and the back substrate; a plurality of strings, each of the plurality of strings comprising a series of bifacial solar cells adjacent to each other electrically connecting the plurality of bifacial solar cells adjacent to each another in the column using an interconnector; a plurality of lead wires to electrically connect an interconnector of the plurality of bifacial solar cell at an end of the plurality of strings to an adjacent string; and a junction box connecting the plurality of lead wires on a back side of the back substrate, wherein the junction box and the plurality of bifacial solar cells are not overlapped, wherein a number of bifacial solar cells in one of the plurality of strings in a region where the junction box is located is smaller than a number of bifacial solar cell in another one of the plurality of strings in a region where the junction box is not located, and wherein the other of the strings is located at an outer portion of the solar panel and the one of the plurality of strings is located at an inner portion of the solar panel.
