Claim 0:
1. A solar module, comprising:
solar cells;
and electrode lines,
wherein each of the solar cells comprises a solar cell substrate and a plurality of busbars located on one side of the solar cell substrate,
wherein each of the electrode lines has an end connected to a busbar of the plurality of busbars on a front surface of one solar cell of the solar cells and another end connected to the busbar on a rear surface of another solar cell of the solar cells that is adjacent to the one solar cell,
wherein first electrode pads are provided at the busbar, a number of the first electrode pads ranges from 6 to 12, and
wherein a relation between a diameter of each of the electrode lines and a number of the plurality of busbars is 2.987x−1.144−1.9<y<3.2742x−1.134+1.7, where x denotes the diameter of each of the electrode lines in millimeters and y denotes the number of the plurality of busbars;
wherein the solar cells have lengths and widths that are equal, ranging from 200 mm to 220 mm;
wherein the first electrode pads comprise first sub-electrode pads and second sub-electrode pads, and fingers are provided on the solar cell substrate and intersect with the busbar, and the fingers are electrically connected to the busbar, and wherein in a direction perpendicular to the solar cell substrate, orthographic projections of part of each of the second sub-electrode pads on a plane of the solar cell substrate do not overlap with orthographic projections of the fingers on the plane of the solar cell substrate;
wherein the diameter of each of the electrode lines ranges from 0.2 mm to 0.33 mm; and
wherein a width of the busbar ranges from 20 μm to 50 μm.
