Embodiment example 1
[0026] Depend on figure 1 , figure 2 It can be seen that each photovoltaic module 1 is composed of M (M=120) cells 2, and the M cells 2 are divided into P (P=3) groups, and each group of cells 2 is divided into left and right groups. , the right two parts,
[0027] The battery slices 2 of the battery string I6 in the first group are distributed in the column I (I is within the integer range of 1-7) and the row J (J=1, 2, 3), and the battery slices 2 of the battery string II7 are distributed in the I ( I is in the range of 8-14 integers) column, J (J=1, 2, 3) row;
[0028] Taking the battery string I6 as an example, the figure 2 It can be seen that one end of the wire 5 is fixed on the battery sheet 2 with J=1 and I=7, and the other end of the wire 5 crosses the first row, and then connects with the battery sheet with J=2, I=1, J=3, I=7 in sequence. =1 cell, J=3, I=2 cell, J=2, I=2 cell, J=2, I=3 cell, J=3, I=3 cell, J=3, I =4 cells, J=2, I=4 cells, J=2, I=5 cells, J=3,...
Embodiment example 2
[0033] Depend on Figure 5 , Figure 6 It can be seen that each photovoltaic module 1 is composed of M (M=132) cells 2, and the M cells 2 are divided into P (P=3) groups, and each group of cells 2 is divided into left and right groups. , the right two parts,
[0034] The battery slices 2 of the battery string I6 in the first group are distributed in column I (I is within the integer range of 1-6) and row J (J=1, 2, 3, 4), and the battery slices 2 of battery string II7 are distributed in I (I is within the integer range of 7-12) column, J (J=1, 2, 3, 4) row;
[0035] Taking the battery string II7 as an example, the figure 2 It can be seen that one end of the wire 5 is fixed on the battery sheet 2 with J=1 and I=12, and the other end of the wire 5 crosses the first row, and then connects with the battery sheet with J=2, I=7, J=2, I=7 in sequence. =8 cells, J=3, I=8 cells, J=3, I=7 cells, J=4, I=7 cells, J=4, I=8 cells, J=4, I =9 cells, J=3, I=9 cells, J=2, I=9 cells, J=2, ...
