Product Description
525-550W Bifacial Dual Glass 10BB Half-cut Mono Perc 144 Half-cell Soalr Panels
Our 525‑550W Bifacial Dual‑Glass 10BB Half‑cut Mono PERC 144‑cell solar panel features 182 mm monocrystalline PERC half‑cut cells with 10‑busbar design, delivering front‑side power output ranging from 525W to 550W and maximum module efficiency up to 21.1%. Thanks to bifacial dual‑glass construction, the module harvests reflected irradiance from the rear side with 70%±5% back‑side output ratio, bringing an extra 5%‑25% energy gain especially for ground‑mount, carport and high‑reflective‑surface installations.
Built with 2.0 mm AR‑coated strengthened front glass and 2.0 mm heat‑strengthened rear glass plus robust anodized aluminium frame, this dual‑glass module achieves outstanding anti‑aging and moisture‑resistant performance. Equipped with an IP68‑rated junction box with optional 3 or 6 bypass diodes and MC4‑compatible connectors, it supports 1500 V DC system voltage and adapts to harsh outdoor conditions from ‑40°C to +85°C. This PV module is available for OEM customisation, well‑suited for large‑scale utility solar farms, commercial and industrial projects.
Key Features
- High front‑side power range: 525‑550W, max module efficiency reaches 21.1%, power tolerance 0~+3%
- Bifacial dual‑glass structure: 70%±5% rear‑side output ratio, delivers extra 5‑25% power gain from reflected light
