We have gone through a lot of new technologies that are employed to produce solar panels on our channel (IBC, Multiple/Multi-Busbar, PERC, Bifacial, Heterojunction, etc) & today is the day of discussing half cut or half size cells.
According to CleanEnergyReviews, another recent technology is using half cut or half size cells rather than full-size square cells and moving the junction box to the center of the module. This effectively splits the solar panel into 2 smaller panels of 50% capacity each which work in parallel. This has multiple benefits including increased performance due to lower resistive losses through the bus bars (current collectors). Since each cell is the half size it produces half the current at the same voltage which means the width of the busbar can be reduced by half, in turn, reducing cell shading and losses. The lower current also translates to lower cell temperatures which in turn reduces the potential formation and severity of hot spots due to localized shading, dirt or cell damage.
In addition, the shorter distance to the center of the panel from the top and bottom improves efficiency overall can boost the power output of a similar sized panel by up to 20W. Another benefit is that it allows partial shading on the upper or lower part of the panel to not affect the entire power output of the panel.
Hanwha Q Cells have now gone one step further and introduced the Q.Peak Duo G5 series of split panels using half-cut mono PERC cells with 6 round wire busbars. ——–***——-
