LR7-54HJBB-490M

Longi Solar S10 Double Glass Premium Black (LR7-54HJBB) 490-505M modules are designed for maximum energy production from limited roof surfaces – without compromising on aesthetics. Their key feature is the combination of a heterojunction with back-contact (HIBC) structure, ensuring a uniformly black module front while maximizing light capture even under less-than-ideal conditions. The double glass construction enhances operational stability and resistance to environmental factors, which is especially noticeable in installations exposed to significant temperature fluctuations or challenging weather conditions.

The main advantage of this series is its high tolerance to partial shading and minimized losses, which are common issues in many homes due to chimneys, window frames, or trees. The applied technology also reduces the risk of hot spots, contributing to safety and long-term reliability. This makes it an excellent choice for demanding premium rooftop installations where maximum yield per square meter and the total-black appearance – whether for new builds or renovations – are key priorities.
