Abstract

A solar module having at least two substring groups, each including an upper substring having solar cells connected in series and arranged in a matrix having two adjacent columns and a plurality of rows, and a lower substring having solar cells connected in series and arranged in a matrix having two adjacent columns and a plurality of rows. The lower and upper substrings include the same number of solar cells. A cross-connector interconnects the lower and upper substrings electrically in parallel forming the substring group. A bypass diode is arranged electrically in the cross-connector, and cross-connectors of each substring group are interconnected electrically in series. Two columns of the lower substring include a different number of solar cells and two columns of the upper substring include a different number of solar cells, such that the number of solar cells of the upper substring and of the lower substring is odd.

Dependent claims

A solar module having at least two substring groups, each substring group comprising

an upper substring having a number of solar cells that are connected in series, wherein the solar cells of the upper substring are arranged in a matrix form comprising at least two adjacent columns and multiple rows,
a lower substring having a number of solar cells, that are connected in series, wherein the solar cells are arranged in a matrix form comprising at least two adjacent columns and multiple rows and wherein the lower substring and the upper substring have the same number of solar cells
a transverse connector electrically connecting the lower substring and the upper substring in parallel to form the substring group and
a bypass diode that is electrically arranged in the transverse connector,
wherein the transverse connector of each substring group are in contact with one another in such a manner that the substring groups are electrically connected to one another in series, and
two columns of the lower substring have a different number of solar cells and two columns of the associated upper substring in the substring group have a different number of solar cells, with a result that the number of solar cells of the upper substring and the number of solar cells in the lower substring is uneven.
