Patent ID: 8586855

Claim:
A solar cell module comprising: a solar cell panel including an array of solar cells defining a plurality of strings, the plurality of strings including two outer strings positioned closest to two outer edges of the solar cell panel, each of the plurality of strings including a plurality of solar cells in electrical connection and arranged in a row; a plurality of interconnectors electrically connecting the plurality of solar cells of the strings; a junction box that receives electric current generated from the plurality of strings; a plurality of lead wires electrically coupling the junction box to the plurality of interconnectors; and an insulating layer insulating the plurality of lead wires from the solar cells and the plurality of interconnectors, wherein the plurality of lead wires are arranged such that they do not overlap with each other, wherein two lead wires that are connected to an interconnector of a respective outer string include an interconnector connection part connected to the interconnector of the respective outer string, a junction box connection part coupled to the junction box, a first coupling part coupled to the interconnector connection part such that the first coupling part is orthogonal to and intersects the interconnector connection part, and a second coupling part coupled to the first coupling part and the junction box connection part, the second coupling part being arranged parallel to the interconnector connection part, wherein a width of the insulating layer is equal to or larger than a distance between the first coupling parts of the two lead wires that is connected to the interconnector of the outer strings.
