Sunnasmart 590W Bifacial Dual-Glass Monocrystalline Solar Panel (SKT590M10-144D5)

Product Overview: The Sunnasmart SKT590M10-144D5 is a high-performance 590W bifacial dual-glass monocrystalline solar module engineered to deliver maximum power density and superior financial ROI for commercial, industrial, and ground-mounted utility-scale arrays. Powered by advanced M10 (182mm) half-cut multi-busbar (MBB) cell technology, this heavy-duty panel achieves an outstanding module efficiency of 22.8%+ from the front surface alone. Driven by its precision dual-glass architecture, it captures reflected light from the rear side, generating an additional up to 25% bifacial energy yield boost depending on the surface albedo. Housed in an ultra-ruggedized anodized aluminum alloy frame (AL6005-T5 spec equivalent) with IP68 junction boxes, it provides uncompromising structural resilience against extreme wind/snow loads and severe coastal salt-spray environments, making it the premier choice for premium global solar installations.
