Key Features of the Q.PEAK DUO BLK ML-G10+

1. Q.ANTUM DUO Z Technology

This is Qcells’ signature half-cell PERC technology. By splitting each solar cell in half, resistive losses are reduced and shading tolerance is improved. The “Z” refers to zero-gap cell design, which increases active cell area for higher efficiency.

2. All-Black Aesthetic

The uniform all-black design makes the panel a favorite among homeowners concerned about appearance. It blends into rooftops more naturally than silver-framed or blueish modules.

3. Strong Durability

Built with robust materials and tested for high snow and wind loads, the G10+ is designed to withstand tough conditions while maintaining long-term performance.

4. 25-Year Warranty Coverage

Both product and performance warranties last 25 years, ensuring peace of mind for homeowners making a long-term investment.

Real-World Performance

In Hot Climates

The G10+ performs well, but with a temperature coefficient of -0.34%/°C, it loses more output in extreme heat compared to N-type or HJT panels (-0.25%/°C).

In Snowy Regions

Excellent performance thanks to strong snow load ratings and the ability of black surfaces to shed snow faster under sunlight.

In Coastal Areas

The G10+ is certified for salt-mist resistance, making it a reliable choice for coastal installations.

Shading Performance

Thanks to the half-cell design, the panel handles partial shading better than traditional full-cell panels, reducing overall system losses.
