Product Description

435-455w-9bb-half-cut-mono-perc-144-cell-solar-panels

Our 435‑455W 9BB half‑cut monocrystalline PERC solar module integrates advanced 9‑busbar, half‑cut and Mono PERC cell technologies, delivering power output ranging from 435W up to 455W with maximum module efficiency reaching 20.9%. Built with 144 series‑connected monocrystalline silicon cells (6*24 layout), this PV panel optimizes internal current loss and enhances energy yield under both standard and real‑world NMOT operating conditions.

Featuring robust mechanical construction including 3.2mm AR‑coating tempered front glass and anodized aluminium alloy frame, the module supports up to 1500V DC maximum system voltage and handles heavy mechanical loads (5400Pa front /2400Pa rear), performing reliably across extreme ambient temperatures from ‑40°C to +85°C. Equipped with IP68‑rated junction box with 3 bypass diodes and multiple optional connector types, this OEM‑available solar panel fits perfectly for residential rooftops, commercial installations and ground‑mount utility‑scale solar projects, offering stable power generation and flexible bulk packing solutions for global shipments.

Key Features

High‑Efficiency 9BB Half‑cut Mono PERC Design

Adopts 9‑busbar half‑cut monocrystalline PERC 144‑cell configuration; power output spans 435‑455W, peak efficiency hits 20.9%. Half‑cut cell structure reduces internal resistance and hot‑spot risk, improving actual power generation performance.

Excellent Temperature Adaptation

Temperature coefficient of Pmax at ‑0.36%/°C, Nominal Module Operating Temperature (NMOT):43±2°C. Maintains consistent energy output even in high‑temperature environments, minimizing power loss under hot climate conditions.

Superior Mechanical Durability & Weather Resistance

3.2mm AR anti‑reflection tempered glass plus heavy‑duty anodized aluminum frame. Front mechanical load up to 5400Pa, rear side load 2400Pa, well resistant to snow and wind pressure. Operating temperature range:‑40℃ ~ +85℃, adapts to diverse harsh outdoor scenarios.

Reliable Electrical Safety Performance

IP68 waterproof & dustproof junction box built‑in 3 bypass diodes to mitigate shading‑caused power loss.
