Product Description

435-455W Bifacial Dual Glass 9BB Half-cut Mono Perc 144-cell Solar Panels

Our 435‑455W bifacial dual‑glass solar module integrates 9‑busbar half‑cut Mono PERC cell technology, delivering front‑side power output spanning 435W‑455W with maximum module efficiency reaching 20.9%. Built with 144 series‑connected monocrystalline silicon cells (6*24 layout), this bifacial panel features a 70%±5% bifaciality factor, harvesting sunlight from both front and rear surfaces to gain extra power up to 25% from reflected ambient light.

Adopting 2.0 mm double‑sided semi‑tempered glass plus anodized aluminium alloy frame, the dual‑glass structure eliminates backsheet ageing risk and improves long‑term reliability. Rated for 1500V DC maximum system voltage, it withstands‑40°C ~ +85°C wide operating temperature range, front mechanical load up to 5400Pa and rear load of 2400Pa. Equipped with IP68 junction box containing 3 bypass diodes, multiple optional connector types and customizable output cables, this OEM‑supported PV panel excels for ground‑mount solar farms, carports, commercial rooftops and high‑reflective installation sites, with optimized container‑loading packing solutions for global bulk shipments.

Key Features

Bifacial Dual‑Glass High‑Yield Design

9BB half‑cut Mono PERC 144‑cell configuration; front‑side power 435‑455W, peak efficiency 20.9%. 70%±5% bifaciality factor enables rear‑side power gain from 5%‑25%, boosting actual energy output under reflective ground conditions. Dual 2.0 mm semi‑tempered glass construction removes traditional backsheet failure risks for extended service life.

Optimized Half‑cut 9BB Cell Technology

Half‑cut cell design lowers internal resistance and hot‑spot probability; 9‑busbar layout reduces current loss to secure stable power generation under STC and NMOT real‑world test conditions. Power output tolerance: 0~+5W for guaranteed positive power deviation per module.

Outstanding Temperature Performance

Temperature coefficient of Pmax:‑0.36%/°C; Nominal Module Operating Temperature (NMOT):43±2°C. Retains solid power output under high‑temperature working environments, minimising thermal‑induced power loss for hot‑climate projects.

Superior Mechanical Strength & Weather Resistance

Front & rear 2.0 mm AR‑coating glazed semi‑tempered glass paired with robust anodized aluminium frame. Front mechanical load 5400Pa, rear load 2400Pa for strong wind and snow‑load resistance. Operating temperature range:‑40°C ~ +85°C, suitable for harsh outdoor scenarios such as ground‑mount plants and coastal installations.

Complete Electrical Safety Specifications

IP68 waterproof and dust‑proof junction box built‑in 3 bypass diodes to mitigate shading‑triggered power drop. Max system voltage supports 1500V DC; maximum series fuse rated 25A, Safety Protection Class II. Multiple connector selections: T01 / LJQ‑3‑CSY / MC4 / MC4‑EVO2; output cables 4mm²(IEC)/12AWG(UL), cable length customizable upon request.

OEM‑Ready & Cost‑Effective Bulk Packaging

Available for OEM customisation. Standard packing:36 pieces per pallet; 792 pieces per 40’HQ container (648pcs for USA version), optimised container fill rate to cut down global wholesale logistics cost.

Wide Application Compatibility

Perfect for utility‑scale ground‑mount solar farms, carport PV systems, commercial & industrial rooftops and installations with high albedo reflection surface. Compatible with both on‑grid and off‑grid solar power systems.
