4 FAQs about Solar panel slices

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.

What is a half cut solar panel?

A half-cut solar cell panel allocates twice the cells in the same area of a regular module. This means two times the arrays of solar cells within one module, with half-cut solar cells having half the width, keeping the area of the panel the same. Generally, modules with 60 solar cells include three substrings of 20 cells in series.

How many cells are in a half-cut solar panel?

Traditional monocrystalline solar panels typically feature 60 to 72 solar cells, therefore cutting those cells in half improves the number of cells. Half-cut panels typically feature 120 to 144 cells and are built with PERC technology, which provides improved module efficiency.

How do half-cut solar panels work?

The panel is then divided in half so that the top and bottom halves act as two independent panels, producing electricity even if one half is shaded. The key to half-cut cell design is a distinct form of panel "series wiring," or how the solar cells are linked together and send power through a bypass diode within a panel.
