Longi 480Wp N-Type Bifacial Glass-Glass Solar Panel LR7-54HVD-480M – Wholesale 36 panels per pallet

LR7-54HVD-480M is LONGi's high-efficiency BC-Cell dual-glass module, built on 108 monocrystalline half-cut cells (6×18). Its full-black glass/glass design pairs strong electrical performance with an elegant, uniform aesthetic suited to residential and architecturally sensitive installations.

Back-contact cell technology removes front-side busbars entirely, improving optical utilization and current collection while boosting both power output and long-term reliability. The BC-cell structure also delivers a lower operating temperature by nature, and the module is built to withstand harsh environments, including high winds, hail, and static loading.

Given its full-black construction, the LR7-54HVD-480M efficiency of 23.5% is quite impressive. Bifacial technology enables additional energy harvesting from the rear side, with a reference bifaciality factor of 70±5%. LONGi backs this module with a 15-year product warranty and a 30-year linear power warranty guaranteeing at least 88.85% output retention.

Higher efficiency of up to 23.5%

LR7-54HVD-480M guarantees outstanding power output. HPBC2.0 back-contact cell technology results in 23.5% module efficiency, with a positive power tolerance of 0~3%.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel's efficiency by only -0.260%.

High quality standards

Every module is engineered to withstand harsh environments and demanding mechanical conditions. Certifications include ISO 9001, ISO 14001, ISO 45001, and IEC 62941, alongside IEC 61215 (design qualification) and IEC 61730 (safety qualification) compliance. The module holds a fire rating of IEC Class C.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 1% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.35%. After 30 years, the modules retain more than 88.85% of their initial output.

Certified for standard wind and snow conditions

LR7-54HVD-480M is certified to withstand 5400 Pa of static front-side loading and 2400 Pa of rear-side loading, along with a 25mm hailstone test at 23 m/s. Such resistance is mainly due to the black anodized aluminum alloy frame and dual-glass construction, with 2.0mm semi-tempered front glass and 1.6mm semi-tempered rear glass.
