Q.PEAK DUO XL-G11S.3/BFG 595W Module

The QCELLS Q.PEAK DUO XL-G11S.3/BFG is a 595-watt bifacial double-glass module that pairs Q.ANTUM DUO half-cell technology with a high-tech aluminum alloy frame. Bifacial Q.ANTUM cells make efficient use of light on the rear side for an energy-yield gain of up to 21%, while the 156-cell, zero-gap layout reaches ≥21.3% module efficiency (up to 21.7% across the series), an ideal solution for commercial and utility solar, ground-mounted power plants, and tracker installations.

The high-tech anodized aluminum alloy frame protects the module from damage and enables a wide range of mounting structures, certified per IEC for high snow loads (5400 Pa) and wind loads (3750 Pa). A double-glass laminate with Advanced Anti-PID, Advanced Anti-LID, and Hot-Spot Protect technology backs a 12-year product and improved 30-year performance warranty, and the module is proudly assembled in the USA.
