Key Parameters

Product description:

Half cell modules have higher power output, better temperature-dependent performance, less shading effect, and low risk of hot spot.

Half cell advantage:

Half cell modules consist of half cells that cut from the ordinary whole cell. One whole sell is cut into two half pieces. Half cell modules have better performance in partial shadow condition. In half cell panels, the power loss is less than that in entire cell panel, since the bypass diodes restrict the loss of power. The by pass diodes creates a substitute path for the current to travel in the unshaded area instead of passing through the shaded parts.

How half cell modules work:

If an entire solar cell is cut into two half pieces, one half piece produce half as much current and one fourth resistance of the whole piece. Thus, the quantity of cells will be double. If they are wired up to work like a full cell panel, the current will be the same but with half the resistance. The electrical losses would be less due to the lower resistance.

Cells connection type

But if the half cut cells were wired together as in a standard full cell panel, they would produce twice the voltage and half the current. To make the output like standard full cell panels, the type of the half cells connection is different. There are two lots of half quantity series-connected cells. These two lots are connected in parallel. Voltages in parallel stay the same and the half cell panel remains the same voltage as the full cell panel.
