Do all solar panels use half-cut cell technology?
Not all solar panel manufacturers use half-cut cell technology, but certain installers may carry half-cut panels. Half-cut solar cells allow photovoltaic solar panels to generate more energy than with traditional, full-cell solar cell setups.
How do half cut solar panels work?
This type of wiring allows panels built with half-cut cells to lose less power when a single cell is shaded because a single-shaded cell can only eliminate a sixth of the total panel power output. Wiring scheme for a solar panel made with half-cut cells. There are six separate "rows" of cells wired together in parallel.
What is solar cell cutting?

As with cell cutting, the stringing process needed when making half-cut cells is a very precise task.
Why are solar panels sliced in half?
A laser is used to carefully chop the cells in half. By halving the current within the cells, resistive losses from transporting energy via current are decreased, resulting in improved performance. Because the solar cells are sliced in half and hence smaller in size, there are more cells on the panel than on regular panels.
