JA Solar 465W double-glass monofacial solar panel
The JA Solar 465W JAM54D40-465/LR solar panel combines N-type cell technology with double-glass construction for commercial, industrial and residential PV systems. Its 23.3% module efficiency helps make effective use of available installation space, while the black frame provides a consistent array appearance.
Key features
- Space-efficient generation: 465W rated output in a 1,762mm-long module, suitable for projects where roof layout and module dimensions matter.
- N-type Bycium+ cells: 108 half-cells with 16-busbar technology and a high-density module design.
- Double-glass construction: 1.6mm anti-reflection-coated front glass and 1.6mm heat-strengthened rear glass.
- Front-side generation: monofacial design, with no rear-side energy gain assumed in the system’s output calculations.
- Long-term performance cover: 30-year linear power-output warranty, with 1% first-year degradation and 0.4% annual degradation thereafter, subject to manufacturer terms.
Where to use
Consider the JA Solar 465W double-glass monofacial solar panel for warehouses, logistics facilities, commercial offices, agricultural buildings, residential roofs and suitably designed ground-mounted arrays. Select module quantities and string layouts around the available area, local shading and the inverter’s electrical limits.
Double-glass construction does not make this LR module bifacial. Design the installation around front-side generation and use mounting hardware approved for its 30mm frame, dimensions and fixing positions, with a structural assessment where required.
Energian can assist with module selection, mounting compatibility, inverter string design and DC protection. This panel requires professional system integration; installation can be arranged through trusted partners.
