Jolywood JW-HD96N-R2 460W Solar Panel The high-efficiency bifacial PV module from the NIWA Black series is based on modern n-type J-TOPCon cells. The panel combines 460W of power, 23.0% efficiency, bifacial generation, and a durable double-tempered glass design. N-type technology ensures stable generation without the light-induced LID degradation typical of traditional cells. Jolywood also highlights improved low-light performance and an optimized temperature coefficient of 0.280%/°C, allowing the panel to operate efficiently even at elevated temperatures. The bifacial design allows for the use of light incident on the rear surface of the module. The official bifacial efficiency is 80%. For the 460W version, Jolywood cites a power output of up to 598W with a 30% gain from the rear. Actual gain depends on the surface area beneath the panel, the mounting angle, and lighting conditions. The module features a black finish, thin busbars, and a transparent double-sided glass-on-glass design, making it suitable for both home solar power systems and commercial systems and projects where performance and a neat appearance are important. The panel is rated for system voltages up to 1500VDC, an operating temperature range of -40°C to +85°C, and a mechanical load of up to 5400Pa from the front.
