Half-cell technology in solar modules represents a significant advancement in reducing energy loss under partial shading. When conventional solar panels are partially shaded, a considerable portion of their energy output is lost. However, by employing half-cell technology alongside Multi-BUSBAR technology, the solar cell is divided into smaller sections, mitigating this loss. As a result, solar modules equipped with this technology demonstrate enhanced efficiency, enabling the solar system to generate more energy even under partial shading conditions.
Advantages of half-cut solar cells while shaded
There are some clear advantages to half-cut cells such as reduced resistive losses and reduced hot spotting impacts. However, a portrait installation is necessary to make use of the advantages a half-cut cell provides in shaded conditions. Ideally, you would orient the array so that shading occurs in the lower half of any given row of modules. Certain sites may not always have the room for a portrait install, and depending on the orientation of the site, the shading conditions, and additional installation considerations may not warrant the increased costs that come with half-cut modules. If a site does not experience heavy shading conditions there may not be much difference in the shaded performance between half-cut and standard modules. All of these considerations also need to be weighed up against the advantages that half cut cells provide, and now you’re better equipped to take advantage of them.
