Optimum Efficiency

210mm x 105mm Half-Cell Modern Technology

The 400w solar panels use the effective 210mm x 105mm HJT half-cell technology. With symmetrical front and rear ends, a bifaciality of 85 ± 5% is accomplished. In addition, the outstanding temperature level coefficient of HJT enables capturing much more sunshine and transforming it into electricity.

Full Black Layout

A complete black 400w solar panel means it sporting activities an evenly black appearance across its entire surface: cells, framework, and backsheet. There is no considerable difference in performance compared to blue or black/white components, yet full black is taken into consideration by numerous to be a lot more aesthetically appealing.

Additional Product Advantages

• Low hot spot risk:

The half-cut cell design reduces the risk of hot spots, which can damage solar cells and lower efficiency.

• Ultra-high bifaciality:

HJT bifacial 400w solar panels can generate electricity from both the front and rear sides of the panel, resulting in up to 30% more power generation in ideal conditions.

• Crack resistance:

The double glass encapsulation protects the solar cells from moisture and mechanical stress, making them more resistant to cracks and other damage.

• Shade tolerance:

The half-cut cell design improves the module’s shade tolerance, so that it can still generate power even if part of the panel is shaded.

• PID Defense by Design:

Traditional solar cells can suffer from PID, a phenomenon that reduces power output over time. HJT technology eliminates this issue. The secret lies in the cell structure. Unlike conventional cells, the surface of HJT cells utilizes a Transparent Conductive Oxide (TCO) film. This brilliant design eliminates the need for insulating layers, a key culprit in PID. Since TCO conducts electricity effectively, it structurally prevents PID from occurring.

• 30-Year Product Warranty

HJT solar panels make use of double-glass style, which supplies superb weather resistance, rust resistance, and longevity. In addition, the POE encapsulant film integrated in these solar panels provides impressive dampness barrier abilities, anti-PID efficiency, and maturing resistance. These functions, generally, contribute to a 30-year item and efficiency guarantee for the HJT photovoltaic panels.
