530-550W Bifacial Dual Glass 10BB Half-cut Mono Perc PV Modules

Category: Monofacial Solar Panels
Features

This bifacial double-glass monocrystalline solar module features 144 half-cut cells with 10-busbar technology, delivering front-side power output ranging from 530W to 550W. Built with 2.0mm semi-tempered glass on both front and rear sides, the module achieves superior durability, anti-PID performance and long-term reliability for outdoor solar installations. Thanks to its bifacial design, the rear side can capture reflected albedo light, bringing 5%~25% extra power gain depending on ground reflectivity. It adopts an IP68 waterproof junction box with 3 bypass diodes to mitigate power drop caused by partial shading. With a low temperature coefficient of Pmax at -0.35%/°C, it maintains stable power generation even under high-temperature working conditions.

Product Description

530-550W Bifacial Dual Glass 10BB Half-cut Mono Perc PV Modules

Thanks to its bifacial design, the rear side can capture reflected albedo light, bringing 5%~25% extra power gain depending on ground reflectivity. It adopts an IP68 waterproof junction box with 3 bypass diodes to mitigate power drop caused by partial shading. With a low temperature coefficient of Pmax at -0.35%/°C, it maintains stable power generation even under high-temperature working conditions.

The module is fitted with anodized aluminum alloy frame for structural strength. For logistics, 36 modules are packed per pallet; 720pcs fit into a standard 40'HQ container, while 576pcs for USA shipment. It is an ideal solution for utility-scale solar farms, ground-mounted projects and commercial distributed PV systems pursuing higher energy yield.
