A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency.

A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. In some variations a solar module comprises a white backing sheet on which rows of super cells are arranged, and the white backing sheet comprises darkened stripes having locations and widths corresponding to gaps between the rows of super cells such that white portions of the backing sheet are not visible through the gaps between the rows of super cells.
