Product description

Trina Solar Vertex S+ NEG9R.28 445 W – N-type i-TOPCon module with double glass

Product description

Trina Solar Vertex S+ 445 W (NEG9R.28) is a high-efficiency photovoltaic module based on N-type i-TOPCon technology, characterised by low degradation and increased energy yield over the lifetime of the system. The dual-layer double-glass construction significantly increases resistance to environmental conditions, and the electrical parameters – including voltage Vmp 44.3 V, current Imp 10.05 A and efficiency 22.3% – make the module an attractive solution for residential and commercial buildings. Long-term reliability is ensured by a 25-year product warranty and a 30-year linear performance warranty.

Applications

Rooftop installations on residential buildings
Commercial systems and small C&I installations
