ZTT-NG54CDB-470-485W

N type BC dual glass module for residential applications.Its grid free front surface delivers a full black aesthetic. Balancing high efficiency with superior weather resistance, this module effectively addresses residential rooftop challenges – including partial shading, summer heat, and aesthetic requirements – making it an ideal choice for homes and small C&I rooftops alike.

Product Advantages

Reliable Performance:The dual‑glass design is backed by a 30‑year linear warranty, with first‑year degradation of <1% and an annual degradation rate of 0.35% thereafter.
Stable Output:BC cells maintain 70% of rated power output under partial shading, effectively minimizing generation losses caused by rooftop obstacles.
Aesthetic Design: With zero front‑side grid lines, the module achieves a sleek full‑black appearance and up to 23.8% efficiency, blending seamlessly with tile roofs, color‑coated steel roofs, and a variety of residential architectural styles.
Excellent Temperature Resistance:The module effectively suppresses hotspot risks, as it reduces cell temperature by over 60°C under shading conditions, complemented by a low temperature coefficient of –0.26%/°C.
