Longi LR7-54HVD-485M

The Longi LR7‑54HVD‑485M is a bifacial glass‑glass PV module of the Hi‑MOX10 series with a rated output of 485Wp and HPBC‑2.0 cell technology. The fully rear‑contacted cell structure maximizes the active module area and supports a module efficiency of 23.8% with compact dimensions of 1,800×1,134mm. The glass‑glass design increases mechanical stability and reduces age‑related performance losses, while the bifacial layout enables additional yields from rear‑side irradiation. With a maximum system voltage of 1,500V, the module is suitable for modern high‑voltage strings and supports long string lengths in commercial and industrial installations. The EVO2A DC connector, a power tolerance of 0/+3%, and a tested mechanical load capacity of 3.6kPa underline its suitability for planning‑intensive rooftop and ground‑mounted projects.

• Module technologyThe HPBC‑2.0 cell technology is based on fully rear‑side contact, eliminating front metallization and minimizing optical shading. In combination with the 108‑cell half‑cell layout, this improves current flow within the module and reduces internal electrical losses. The bifacial double‑glass construction allows the use of rear‑side irradiation and increases energy yield, especially on bright surfaces or with elevated mounting. Anti‑reflective coating on the glass surface improves the incidence behavior of diffuse light and supports stable yields under varying irradiance conditions.
  
  Technological core elements
  • HPBC‑2.0 cells without front busbars, optimized light utilization and high area output of 238Wp/m²
  • Bifacial glass‑glass design for utilizing rear‑side irradiation under suitable mounting conditions
  • Half‑cell design to reduce resistive losses and improve partial‑load performance
  • ARC‑coated solar glass to improve yield at shallow angles of incidence
• QualityThe module complies with the relevant IEC61215 and IEC61730 standards and is qualified for long‑term outdoor use. The glass‑glass construction increases structural integrity and provides additional protection of the cells against moisture and mechanical stress. With a weight of 23.5kg, handling on standard mounting systems remains practical, while the black frame and white appearance enable uniform integration into project‑specific module fields. The tested design loads of 3,600N/m² pressure and 1,600N/m² suction support use in regions with increased snow and wind loads.
  
  Quality‑relevant features
  • Certification to IEC standards for electrical safety and long‑term mechanical stability
  • Glass‑glass construction for improved resistance to moisture and microcracks
  • High tested mechanical load capacity for demanding static requirements
  • EVO2A connectors as an established industry standard for DC connections
• SustainabilityThe high module and area efficiency reduces material use per installed capacity and supports optimized land use in projects with limited space. The long technical service life of the glass‑glass construction has a positive effect on the overall environmental balance by extending replacement cycles. In addition, the module is registered with the German WEEE authority and integrated into existing take‑back and recycling schemes, supporting orderly end‑of‑life treatment.
