Show series description

The Q-Cells Q.PEAK DUO RSF XL-G11S series are bifacial modules featuring a glass-glass structure, specifically designed for large ground installations, particularly on trackers. The most significant practical difference is the robust steel frame (RSF) with advanced anti-corrosion coating – it increases resistance to field conditions and facilitates achieving a stable structure under demanding loads. The series also focuses on faster installation: special positioning solutions help installation teams efficiently align the modules and minimize risks during the mounting phase.

From the yield perspective, bifacial capability is key – the rear side of the module can genuinely contribute energy when the installation is on a light-colored ground surface or an asphalt surface with good reflectivity. Inside, Q.ANTUM monocrystalline cells operate, supported by PID and LeTID protection, as well as Hot-Spot Protect, making it easier to maintain performance over time. This is the choice for investors who prioritize LCOE, construction speed, and reliability, rather than just the specifications from the datasheet.
