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. Another positive attribute of this type of solar panel is its efficient power production at lower tilt angles vs. standard panels. These panels are offer the superior performance of half-cell modules which maximize the amount of light PV cells capture, while also reducing the amount that is reflected. These also dissipate heat more efficiently, altogether boosting energy harvest. With an improved bifacial ratio and superior power temperature coefficient the Longi 445W Bifacial Solar Panel outperforms other modules in the market, achieving a power generation gain of up to 3%. Longi solar panel performance characteristics over 30 years. Another fantastic attribute of the Longi 445W Bifacial Solar Panel is its longevity. 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.
