410W-420W Solar Panel 31V 13.2A Half-Cell Technology 21.3% Efficiency 1722x1134mm Photovoltaic Module
High-efficiency 410W-420W solar photovoltaic panels featuring half-cell technology for superior performance in shaded conditions. Available for OEM customization with voltage output of 31V and current range of 12.7-13.2A.
Our solar panels utilize innovative half-cell technology where standard solar cells are cut into halves, creating two separate and identical solar cell arrays with independent current paths.
When partial shading occurs, only one array's current is affected while the other continues producing power effectively. This design reduces affected working areas by 50% during shading conditions, minimizing power loss and reducing hot spot effects.
