For high-end residential rooftop projects, homeowners often face a dilemma： high efficiency or roof aesthetics？ JinkoSolar‘s new 48QL6-DB and 48QL6-DV all-black dual-glass modules provide the perfect answer.
These modules cover 460W to 485W, built on the enhanced N-type TOPCon platform, with mass-production efficiency up to 24.27%. The all-black design – black frame, black backsheet (dual-glass naturally dark), black junction box – virtually disappears on dark roofs, making them a favorite among architects and premium homeowners.
Key Advantage 1： Dual-Glass, Ultra-High Load Capacity
Dual-glass construction not only enhances aesthetics but also delivers exceptional mechanical strength. Certified to withstand 6000Pa front-side load (≈300kg/m²) and 4000Pa rear-side load. Heavy snow or strong winds won‘t compromise performance. The dual-glass structure also eliminates moisture ingress, minimizing PID risk – ideal for coastal or high-humidity environments.
Key Advantage 2： N-type TOPCon for All-Weather Efficiency
Employing N-type TOPCon cells, these modules feature first-year degradation <1% and annual degradation of only 0.35%, retaining over 90% output after 30 years. The temperature coefficient is just -0.26%/°C, significantly outperforming PERC under high heat. Excellent low-light performance ensures power generation at dawn, dusk, and on cloudy days, extending effective generation hours daily.
Key Advantage 3： All-Black Aesthetics, Value Enhancement
Unlike standard modules with silver frames and white backsheets, the 48QL6-DB/DV blends seamlessly with dark roofs. For villas, luxury homes, or historically sensitive areas, all-black modules are often the only acceptable choice – and they can even increase property value.
