Product Description
650 - 670W Bifacial Dual Glass 12BB Half-cut Mono Perc
This 650–670W bifacial double-glass solar panel adopts 12-busbar monocrystalline silicon cells with 132 cells in series, delivering front-side module efficiency up to 21.60%. With a reference bifaciality factor of 70%±5%, rear side can bring 5%~25% extra power gain under reflective ground, greatly improving total energy yield for ground-mounted, agrivoltaic and C&I projects.
Built with dual 2.0mm semi-tempered glass and anodized aluminum alloy frame, the module supports high mechanical load: front side 5400Pa and rear side 2400Pa. It features a low Pmax temperature coefficient of -0.34%/°C, maintaining stable output under high temperature. Rated for 1500V DC system voltage, IP68 junction box with 3 bypass diodes and positive 0~+5W power tolerance, it can reliably work within -40℃ ~ +85℃ wide temperature range. Optimized packaging: 31pcs per pallet, 527pcs (standard) / 465pcs (USA) per 40'HQ container for bulk shipment.
