400W-450W Monocrystalline Solar Panels with 21.3% Efficiency, 1722x1134mm Size, 1500Vdc System Voltage
Our 400W-450W monocrystalline solar panels deliver exceptional performance with up to 21.3% module efficiency, making them ideal for residential, commercial, and industrial solar installations.
Our half-cell modules feature two separated solar cell arrays that significantly improve performance under shading conditions. When partial shading occurs, only half of the module's power production is affected, resulting in up to 50% better shading response compared to conventional panels.
