SUNTECH PV module 420W 1722x1134x30 N-type monofacial (Black Frame)

High efficiency photovoltaic module from the seriesUltra V Pro Mini, designed with innovativeN-Type TOPCon technologyfor maximum efficiency, durability and excellent performance under real conditions. An ideal choice for residential, commercial and industrial solar systems where reliability and long-term efficiency are key.

SUNTECH STP420S-C54/Nshkm+issingle crystal monofacialsolar panel withhalf-cell (Half-Cell)andN-Type TOPContechnology designed to provide high energy density and minimal degradation over time.
Thanks tomultibusbar structure (MBB)and advanced surface passivation, the module ensures better light capture, higher current and excellent stability at high temperatures.

Advantages:

• N-Type TOPCon technology– higher efficiency, less degradation and better resistance to PID and LID effects.

• Multi-Busbar Design (MBB)– increased reliability and better current flow.

• Excellent low light performance– high performance even in cloudy weather, morning and evening.

• Lower operating temperature– higher stability and less loss at high heat.

• High mechanical strength– certified for loads up to 5400 Pa (snow) and 2400 Pa (wind).

• Enhanced environmental sustainability– protection against salt spray, ammonia, dust and sand (IEC 61701, IEC 62716, IEC 60068-2-68).

• Compatible with all standard mounting and inverter systems.
