LR7-54HGBB-445M - All Black, Bi-facial

The Longi 445W Bifacial Solar Panel | LR7-54HGBB-445M is a 54-cell bifacial solar panel offering excellent performance with up to 21.8% peak efficiency. Ideal for ground mount applications, Longi solar panels also feature lower resistive loss with lower operating current, higher energy yields and lower operating temperature. Longi’s new optimized electrical design also reduces hot spot risk and allows for lower operating currents.

Longi’s Hi-MO 7 boasts industry-leading power generation performance and product reliability, ideal for installations where high albedo, high temperature, and limited space are a factor.

The Longi 445W Bifacial Solar Panel comes enclosed in anodized aluminum alloy frames and encased in dual glass 2.0 + 1.6mm semi-tempered glass.

Longi guarantees these solar panels will continue to perform at over 87.4% of their original capacity after 30 years, thanks to Longi’s 25 year materials and processing warranty and a 30 year extra linear power output warranty.
