FIG. 5B is an alternate illustration of the solar array module 500 of FIG. 5A. As shown in FIG. 5B, module 500 includes solar cells 302 electrically arranged in a matrix of electrical rows (ER1, ER2, ER3, and ER4) and columns (C1, C2). For example, ER3 includes cells C and M. Thus the physical rows and electrical row's only partially overlap. The embodiment of FIGS. 5A-5C differs from that of FIGS. 3A-3C in that the electrical matrix is divided into two crisscross matrices. Each crisscross matrix includes an equal number of rows. As shown, electrical rows ER1 and ER2 represent one crisscross matrix and rows ER3 and ER4 represent a second crisscross matrix. Cells B and C are electrically connected to join the two crisscross matrices. The crisscross matrices are formed by crossing connections 510 such as 510a and 510b.
Referring back to FIG. 5A, in order to implement the electrical crisscross matrices of FIG. 5B, cells A, B, C, and B of column C1 are physically inverted, polarity-wise, with respect to cells J, K, L, and M of column C2. Additionally, crossing connections 510 extend across physical rows. For example, connection 510a connects the negative side of cell C in PR3 to the negative side of cell M in PR4.
In operation, current I can flow through any of the paths available, as shown in FIG. 5B.
