Product Description
LONGi Hi-MO 5 LR5-72HBD 535W-555W Bifacial Half-Cut Solar Panel | M10, 1500V, 21.5% Max Efficiency, Dual Glass
The LONGi Hi-MO 5 LR5-72HBD is a 535W–555W bifacial half-cut solar module engineered on the M10 gallium-doped wafer — the ideal choice for ultra-large power plants. It combines advanced half-cell technology, 9-busbar design and integrated segmented ribbons to deliver up to 21.5% module efficiency with only 0~3% positive power tolerance. Built with 2.0+2.0mm dual-glass and a 1500V system rating, it offers globally validated bifacial energy yield, lower operating temperature and long-term reliability backed by a 30-year linear power warranty.
Product Features
- M10 Gallium-Doped Wafer— Lower LID, higher reliability and stable power output over the full service life.
- 9-Busbar Half-Cut Cel— Reduced cell current, lower hot-spot risk and better shading tolerance.
- Integrated Segmented Ribbons — Lower series resistance for superior module efficiency.
- Bifacial Power Gain — Up to 70±5% bifaciality; rear-side gain reaches 681W at 25% gain (545W reference).
- Dual-Glass 2.0+2.0mm Build— Heat-strengthened, high PID resistance and excellent durability for harsh environments.
- 0~3% Power Tolerance & <2% First-Year Degradation— Year 2–30 degradation of only 0.45%/year.
- DC1500V System Voltage — Lower BOS cost and higher system efficiency.
- Proven Mechanical Strength— 5400Pa front / 2400Pa rear static load; passes 25mm hailstone test at 23m/s.
- Extended Warranty— 12-year materials & workmanship + 30-year extra linear power output warranty.
- Full Certifications— IEC 61215/61730, UL 61730, ISO 9001/14001/45001, IEC 62941, TÜV SÜD, SGS, CE.
