Longi proudly introduces the Hi-MO X10 LR7-72HVD — a bifacial, dual-glass solar module built on the revolutionary HPBC 2.0 (Hybrid Passivated Back Contact) cell platform. Designed to push the boundaries of efficiency, reliability, and safety, the LR7‑72HVD redefines what is possible for demanding applications — from industrial rooftops to large‑scale commercial installations.

Unmatched Performance
The Hi-MO X10 LR7-72HVD delivers leading‑edge power output ranging from 640 Wp to 670 Wp, paired with a maximum module efficiency of up to 24.8 %. This makes it one of the highest‑efficiency modules available in mass production today, offering up to 30 W more output than conventional TOPCon products.

Behind this outstanding performance lies the HPBC 2.0 cell technology, which integrates:
A multi‑layer anti-reflection film that boosts short‑circuit current by 2.25 %,
Bipolar Hybrid Passivation increasing open‑circuit voltage to 745 mV,
A zero-busbar (0BB) structure that shortens the current transmission distance and adds up to 5 W of extra power,
Soft-breakdown shading optimizer technology that reduces shading‑induced power loss by over 70 % compared to TOPCon modules.

Superior Thermal Performance and Long-Term Yield
The LR7-72HVD exhibits a power temperature coefficient of -0.26 %/℃, delivering 3 % more power per watt than TOPCon modules at elevated temperatures.
Degradation is deliberately minimised, with only 1 % power loss in the first year and a linear annual degradation of 0.35 % over the remaining 29 years. As a result, the module retains 87 % of its initial power output after 30 years.

Industry Certifications and Warranty
The LR7-72HVD is fully certified according to IEC 61215, IEC 61730 and UL 61730, and meets ISO 9001, 14001 and 45001 standards. It holds a TÜV Rheinland certificate (No. PV 50602768), confirming compliance with international safety and performance requirements.

LONGi backs the Hi-MO X10 LR7-72HVD with:
15-year product warranty on materials and workmanship,
30-year linear power output warranty guaranteeing sustained performance over the module‘s lifetime.
