ZTT-NG54CD-475-500W

N-type BC dual-glass module for residential applications.By eliminating front metal grid lines, it minimizes shading loss while delivering high power output and excellent shading tolerance. Designed for residential and small distributed PV projects seeking high generation returns, the module features a dual-glass structure that ensures long-term reliability and outstanding performance on rooftops prone to shading and high summer temperatures.

Product Advantages

Dual‑glass Durability:Protected by dual‑glass encapsulation, the module offers strong resistance to sand‑wind and aging. It achieves a first‑year power degradation of 1% and an average annual degradation of 0.35% from Year 2 to Year 30, backed by a 30‑year linear power warranty that extends revenue cycles.
High‑efficiency Technology:The module reaches a maximum conversion efficiency of 24.5%, with power output 5% higher than conventional modules of the same size. This enables larger installed capacity on limited rooftop space and boosts overall project returns.
Enhanced Power Generation:An A+ grade anti‑shading design effectively mitigates generation losses caused by rooftop debris and eave shading.
Reliable Safety:The module effectively suppresses local hot‑spot overheating. Under shading conditions, the temperature of shaded areas remains over 60°C lower than that of conventional modules. Combined with an excellent temperature coefficient of –0.26%/°C, it experiences less power drop during high‑temperature summer conditions.
