Half-cell solar panels, also known as split-cell solar panels, are a type of photovoltaic (PV) module that incorporates solar cells divided into two halves. Each half of the solar cell is electrically connected in series, creating two smaller cells within a single module.

The purpose of dividing the solar cells into halves is to reduce the resistive losses and increase the overall efficiency of the panel. When a solar cell is divided into two halves, the current is effectively split between them, resulting in a lower current per cell and reduced electrical losses. This design helps to minimize the impact of shading, cell mismatch, and other factors that can decrease the efficiency of a solar panel.
