Monocrystalline Solar Panel Longi Solar LR7-54HVD-480M Hi-MO X10 Bifacial

Longi Solar LR7-54HVD-480M (Hi-MO X10 series) — a premium-segment bifacial PV module built on innovative N-type TaiRay silicon wafers and advanced HPBC 2.0 cell architecture. Combining these technologies delivers a record efficiency of 23,5%, high resistance to degradation, and stable kilowatt output even with limited solar insolation.

Key technological advantages

• HPBC 2.0 architecture and N-type TaiRay silicon The back-contact design (Back Contact / BC) removes the busbars from the front side. This minimizes cell shading, lowers internal resistance, and prevents localized overheating (the hot-spot effect).

• Bifacial generation Thanks to its ability to capture reflected light on the rear side (from the roof, soil, gravel, or snow), the module delivers up to +5–20% additional output of electricity compared with standard monofacial panels.

• Dual glass (Glass-Glass) A protective layer of tempered glass on both sides ensures maximum sealing and resistance to moisture, UV radiation, and chemically aggressive environments, significantly reducing the risk of microcracks.

• Minimal degradation Power loss in the first year of operation is no more than 1%, and the annual performance decline in subsequent years does not exceed 0.35%. This ensures a high generation rate over 25–30 years.

• High mechanical strength The design is built for extreme weather conditions: it withstands snow loads up to 5400 Pa and wind gusts up to 2400 Pa.

Applications

Thanks to support for system voltages up to 1500V DC and its high power density, the module is a versatile solution for:

1. Residential solar power plants — maximum generation from a limited roof area.

2. Commercial and industrial facilities — fast payback thanks to the increased efficiency of HPBC 2.0.

3. Ground-mounted solar power plants — maximum efficiency gain thanks to bifacial output (Bifacial).

4. Off-grid and hybrid systems — stable battery charging in cloudy weather.
