HALF CUT CELL MODULE

Half-cell modules have solar cells that are cut in half, which improves the module’s performance and durability. Traditional 60- and 72-cell panels will have 120 and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the cells can produce a little more power. Smaller cells experience reduced mechanical stresses, so there is a decreased opportunity for cracking. Half-cell modules have higher output ratings and are more reliable than traditional panels.

“When considering a solar installation, the idea of ‘more’ is at the forefront produce more energy, save (or earn) more money and do more good for the environment,” said Cemil Seber, VP of global marketing and product management for module manufacturer REC. “In the case of rooftops where there is a limited amount of space available, using solar panels with half-cut cell technology can help.
