Y_L columns on a first side 806 of the line 804 include cells 302 inverted, in terms of polarity, relative to the cells 302 on the second side 808 of virtual line 804. That is, each solar cell 302 of the first side 806 is physically inverted with respect to the second side 808, such that the polarity of each solar cell 302 is inverted as shown in FIG. 4: the “+” side of each cell 302 on the first side 806 is shown in at the lower side of each solar cell 302, while the “+” side of each cell 302 on the second side 808 is shown in the upper side of each solar cell 302. It should be noted that electrical connectivity of solar module 800 remain a plain criss-cross matrix.

The matrix of second side 808 is divided along a virtual horizontal line 812 defining X_T physical rows above the line and X-X_T physical rows below the line where physical rows X_T and X_T+1 are adjacent physical rows on either side of line 812.

Cells 302 in every column on first side 806 are connected in series;

Cells 302 in physical rows X_T to X on the first side 806 are electrically connected in parallel, wherein physical row X_T includes serial units 824, having, in this example, 2 solar cells 302 in each column.

Cells 302 in every column of the upper section 818 of second side 808 are connected in series.
