Trinasolar 520W Vertex S+ Dual Glass N-type i-TOPCon Black Frame Solar Panels
- 520W rated output and 23.4% module efficiency for rooftop projects where available space matters.
- Dual-glass construction with a black aluminium frame, measuring 1961 × 1134 × 30mm.
- 15-year product warranty and 30-year power guarantee, subject to Trinasolar’s applicable warranty terms.
Trinasolar 520W Vertex S+ dual glass solar panel
The Trinasolar 520W Vertex S+ dual glass solar panel combines N-type i-TOPCon monocrystalline cells with 23.4% module efficiency and a black frame. Part of the TSM-NEG18R.28 range, it provides 520W rated output in a module under two metres long. Its monofacial design generates from the front surface; dual glass describes the construction, not rear-side generation.
Key features
- 520W rated output under standard test conditions, with a maximum power voltage of 34.1V.
- N-type i-TOPCon monocrystalline technology with 108 cells and a power temperature coefficient of −0.29%/°C.
- 1.6mm heat-strengthened glass on both sides, with an anti-reflective coating on the front glass.
- Mechanical performance stated up to 5400Pa positive load and 2400Pa negative load, subject to the approved mounting arrangement.
- 30-year power guarantee showing 87.4% retained rated output at year 30.
Where to use
Suitable for professionally designed commercial and industrial rooftops, warehouses, logistics facilities, agricultural buildings and larger residential arrays. It can also be considered for carports and ground-mounted systems where the module dimensions, mounting arrangement and electrical characteristics suit the project.
Select mounting equipment compatible with the 30mm frame and Trinasolar’s approved fixing positions. Confirm inverter input-current limits, string voltage at the site’s minimum design temperature and the exact connector supplied. Mechanical load ratings do not replace a site-specific structural assessment.
