Abstract
A solar device includes a first string of first solar wafers, wherein a plurality of the first solar wafers each overlap with at least one vertically adjacent solar wafer from the first string. Additionally, the solar device includes a second string of second solar wafers, wherein a plurality of the second solar wafers each overlap with at least one vertically adjacent solar wafer from the second string, wherein a plurality of the first solar wafers overlap with one or more of the plurality of second solar wafers to electrically connect horizontally adjacent solar wafers in parallel.

A solar device, comprising:
- a first string of first solar cells, wherein a plurality of the first solar cells each overlap with, and are electrically connected to, at least one vertically adjacent solar cell from the first string;
- and
- a second string of second solar cells, wherein a plurality of the second solar cells each overlap with, and are electrically connected to, at least one vertically adjacent solar cell from the second string,
- wherein, for a plurality of the first solar cells, the first solar cell is horizontally adjacent to and overlaps with one of the plurality of second solar cells in a region to form a shingled arrangement and the first solar cell is electrically connected to the one of the plurality of second solar cells in the region of overlap in parallel.
