Durable Topcon Monocrystalline Solar Panels 440W 120 Cells

Featuring next-generation TOPCon (Tunnel Oxide Passivated Contact) cell technology, delivering significantly higher conversion efficiency and lower degradation than conventional PERC modules for great

The 460W model reaches a module efficiency of up to 21.3%, generating more power per square meter and effectively reducing BOS and levelized cost of energy (LCOE).

Six power tiers from 435W to 460W provide flexible selection for rooftop and ground-mount projects of various scales.

Positive-only power tolerance of 0 to +5W guarantees every module delivers at least its rated output, protecting project ROI.

Compatible with 1500Vdc (IEC/UL) systems, allowing longer strings, fewer combiner boxes and cables, and lower BOS cost for utility-scale plants.

5400Pa front / 2400Pa back static load, -40C to +85C operating range, and IP68-rated junction box ensure reliable performance in sand, snow, high-temperature and high-humidity environments.

Annual power degradation of <=0.46% from year 2 to 30 ensures sustained energy output and maximizes lifetime project revenue.

Certified to IEC 61215 / IEC 61730 for module design and safety, with ISO 9001, ISO 14001 and ISO 45001 management system certifications for assured quality and delivery.
