The SunPower 405W solar panel is designed with LID-resistant solar cells (G12, 210mm), offering high efficiency, a lower temperature coefficient, and front-side conductive wires that enhance current collection. Its proprietary shingled-cell design maximizes durability. It uses reinforced cell connections to endure temperature fluctuations, redundant electrical paths to minimize cell crack impacts, and advanced architecture to reduce shading effects and prevent hot-spot formation. These features enable the panel to deliver more lifetime energy than standard solar panels.
