Product Description

Longi Hi-MO4m LR4-72HPH Mono 435W ~455W 120 Cell Solar Panels

1.Half-Cell Modules:
The power of half-cell module increases, and the hot spot temperature reduces because of lower working current

2. Electrically Compatible
Operating current lower than 11A; Good for distributed generation applications; Matches with various inverters and optimizers; Avoids wiring loss.

3. Multiple Size Configurations:
Standardized width, choice of three different lengths, full utilization of limited roof area, realizing the maximum installed capacity

4. Gallium-doped Technology:
Gallium-doped technology overcomes LID degradation and guarantees the long-term power generation of the module.

5. Multi-busbar Design:
Our nine-busbar design further improves current collection capabilities.

6. Installation on Any Roof:
Flexible installation, including pitched roof, flat and angular roof and flat roof with herringbone detail

7. Power Warranty:
1st year degradation ≤2%, linear degradation ≤0.55%/year
