Advantages of half-cell PV panel technology
The main benefits of the half-cell modules for users are a 2-3% higher module performance and higher total yields. In a half-cell module, standard full cells are cut into two equal halves. In addition, the module 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 module, further reducing resistance losses. Mounting the module vertically will also prove beneficial in shading situations. For example, if the lower half of the module 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 modules, therefore, higher wattage classes and higher yields per system can be achieved.
