Half Cell Solar Panels

The main benefits of the half-cell panels for users are a 2-3% higher module output and higher total yields. In a half-cell module, standard full cells are cut into two equal halves. In addition, the panel is also divided into an upper and a lower half and the half-cells arranged thereon.

By dividing the cells, the power generated per cell is halved and resistance losses on cell and module level are reduced to one quarter. In addition, the halved current can significantly reduce the temperature in the cells and therefore reduce the risk of hot spot effects.

The three small junction boxes, each fitted with only one bypass diode, are transferring less heat to the cells below as well. These factors also boost the longevity of the overall system and dividing the module in half will also have an impact on the overall performance. The path of the generated current is shortened by dividing the panel, further reducing resistance losses. Mounting the module vertically will also prove beneficial in shading situations. For example, if the lower half of the panel is shaded, users can still generate a 50% performance with the upper half, while the production of a full cell module completely breaks away. This could be the case with inter-row shading for free-field or tilt-mounted roof installations. With half-cell panels, therefore, higher wattage classes, efficiencies and higher yields per system can be achieved.

There are a few main ways that half-cut cells can boost solar panel output and performance:

1. Reduced resistive losses

One source of power loss when solar cells convert sunlight into electricity, is resistive losses, or power lost during electrical current transport. Solar cells transport current using the thin metal ribbons that cross their surface and connect them to neighboring wires and cells, and moving current through these ribbons leads to some energy loss. By cutting solar cells in half, the current generated from each cell is halved, and lower current flowing leads to lower resistive losses as electricity moves throughout cells and wires in a solar panel.

2. Higher shade tolerance

Half-cut cells are more resistant to the effects of shade than traditional solar cells. This is not due to the cells being cut in half but rather a result of the wiring methods used to connect half-cut cells in a panel. In traditional solar panels built with full cells, the cells are wired together in rows, known as series wiring. In series wiring schemes, if one cell in a row is shaded and not producing energy, the entire row of cells will stop producing power. Standard panels typically have three separate rows of cells wired together, so shade on one cell of one row would eliminate a third of that panel's power production.
