LONGi Explorer 485W Hi-MO X10 HPBC N-Type Mono Solar Panels
- 485 W N-type BC-cell solar panel for high-output residential and commercial rooftop solar PV systems.
- 23.8% module efficiency in a practical 1,800 × 1,134 mm module format.
- 15-year materials and processing warranty with a 30-year extra linear power-output warranty.
LONGi Explorer 485W Hi-MO X10 solar panel
The LONGi Explorer LR7-54HVH-485M is a 485 W N-type monocrystalline solar panel from the Hi-MO X10 range. It uses BC-cell technology and a 3.2 mm coated tempered-glass front to provide high module output in a roof-friendly 1,800 × 1,134 mm format.
With 23.8% module efficiency, this LONGi 485W solar panel is suitable where usable roof area is limited and higher installed capacity is required. It is designed for professionally specified residential and commercial rooftop solar PV systems using compatible mounting equipment, inverters and DC protection.
Key features
- 485 W rated output: Helps maximise installed solar capacity while reducing the number of modules, roof fixings and DC connections required.
- 23.8% module efficiency: High power density using N-type BC-cell technology.
- Single-glass construction: 3.2 mm coated tempered front glass with an anodised aluminium alloy frame.
- High mechanical-load rating: Maximum static loading of 5,400 Pa on the front and 2,400 Pa on the rear.
- Long-term warranty cover: 15-year materials and processing warranty and 30-year extra linear power-output warranty.
Where to use
The LONGi Explorer 485W Hi-MO X10 solar panel is suitable for homes, residential developments, offices, retail units, workshops and commercial rooftop solar PV installations. Its 1,800 mm module length and 21.6 kg weight make it suitable for systems designed around compatible pitched-roof and commercial-roof mounting solutions.
Use a mounting system approved for the exact module frame, size and clamping zones. Confirm roof structure, wind and snow loading, inverter DC input limits, string open-circuit voltage and electrical protection requirements before installation.
Energian can help with panel quantities, mounting compatibility, inverter and optimiser selection, battery integration and complete solar PV system planning. Where a system cannot be used out of the box, installation can be arranged through trusted partners.
