JA Solar 620W N-Type TOPCon Bifacial Solar Panel | DeepBlue 4.0 Pro Dual-Glass PV Module

Scale up your commercial, industrial, or utility-scale photovoltaic projects with the high-performance JA Solar 620W N-Type TOPCon Bifacial Solar Module (DeepBlue 4.0 Pro Series). Built using advanced n-type TOPCon cell technology and multi-busbar (MBB) half-cell configuration, this module significantly reduces internal power loss and delivers an impressive conversion efficiency of up to 23.0%. Engineered with a robust double-glass structure, it captures reflected ambient light from the rear side (with up to 80% bifaciality), boosting total energy yields significantly. It features superior low-irradiance performance on cloudy days, a lower temperature coefficient for high heat resistance, and exceptional mechanical load tolerances (5400 Pa front snow load / 2400 Pa back wind load). Backed by a 12-year product warranty and a 30-year linear power output warranty, it provides long-term financial security and low Levelized Cost of Electricity (LCOE).
