Kind Code:
B2
Abstract:
The present invention provides a half-cut module, comprising a plurality of solar cell strings and a junction box, wherein the plurality of solar cell strings is disposed side by side, and each solar cell string comprises a plurality of half-cut cells connected in series; the number of the solar cell strings is an integral multiple of 4, the solar cell strings are grouped in pairs, positive poles and negative poles of the solar cell strings in each group are disposed in the same direction, and positive and negative poles of the solar cell strings in two adjacent groups are disposed in opposite directions; the solar cell strings in each group are connected in parallel through a bus bar to form a solar cell string group, adjacent solar cell string groups are connected in series through another bus bar to form a cell circuit, and a positive pole and a negative pole of the cell circuit are located at the same side of the half-cut module; and the junction box and the positive and negative poles of the cell circuit are located at the same side, the bus bar at the same side as the positive and negative poles of the cell circuit is connected into the junction box, and a positive pole and a negative pole of the half-cut module are led out from the junction box. The half-cut module provided by the present invention is higher in reliability and conversion efficiency. + 108a 100 109a _] _ i _ -I-zI t_]i__] _ - ] I _IT ]- 7]- yI mI ] x _ 7 7 _7777]- 777] 777777 7777777777 777777 777777777 _I7777 777-- _ 77] Fig.~ig 3(c) ig 4b 777777777777 777777777777 777777777777 7777777777777 77777777777 Fig. 4(aFigg.34cb
