Trina Solar 520W Vertex S+ N-Type TOPCon Monofacial, Dual Glass, Black Frame

Trina Solar 520W Vertex S+ N-Type TOPCon Monofacial, Dual Glass, Black Frame

The Trina Solar TSM-520-NEG18R.28 is a high-efficiency 520W Vertex S+ solar panel for commercial, industrial and larger rooftop PV installations. Its compact, sub-two-metre format delivers high power density while remaining easier to handle than many large-format commercial modules.

Built with 108 N-type i-TOPCon cells, the panel achieves 23.4% efficiency and a low −0.29%/°C temperature coefficient for reliable performance in low-light and warmer conditions.

Its durable monofacial dual-glass construction helps protect the cells against moisture and microcracking. The low-voltage, high-current design supports efficient string layouts, while the black aluminium-alloy frame provides a clean finish.
