Show series description

The HT-SAAE HT54-18X(PD)-F series consists of bifacial mono modules featuring a glass-glass construction, designed to genuinely increase energy yield in locations where every square inch counts, whether on rooftops or in fields. Dual-sided operation harnesses reflected light from the ground surface, offering a noticeable advantage in installations on light-colored roofs, gravel, or with appropriately selected mounting geometry. Meanwhile, half-cut design minimizes internal losses and improves performance under partial shading – crucial in typical urban conditions (chimneys, window frames, trees). A key feature of this series is the glass-glass construction, enhancing atmospheric resistance and stabilizing performance over the long term, thereby reducing the risk of efficiency drops. For investors valuing aesthetics, an optional full black variant is available, easily integrated into modern roofing and façades. This is an excellent choice for homes, small businesses, and projects where monofacial competitive panels simply leave potential energy unrealized.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
