Trina 515W Vertex S+ Dual Glass N-Type i-TOPCon Black Frame Solar Panels
- 515 W N-type i-TOPCon solar panel for high-output residential and commercial rooftop PV systems.
- 23.2% module efficiency with monofacial dual-glass construction and a black anodised aluminium frame.
- 15-year product warranty and 30-year power guarantee for long-term system planning.
Trina Vertex S+ 515W N-type dual glass solar panel
The Trina Vertex S+ TSM-NEG18R.28 515W is a monofacial N-type i-TOPCon monocrystalline solar panel with dual-glass construction and a black anodised aluminium alloy frame. It provides high output in a 1,961 × 1,134 mm module format for residential, commercial and light-industrial rooftop solar systems.
With 23.2% module efficiency, this Trina 515W solar panel can help maximise installed capacity where roof space is limited. Its double-glass construction is designed for projects requiring a robust module structure and a neat black-framed appearance.
Key features
- 515 W rated output: Higher output per module can reduce panel count, roof fixings and DC connections for a given system size.
- 23.2% module efficiency: Uses N-type i-TOPCon monocrystalline cell technology with 108 cells.
- Monofacial dual-glass construction: 1.6 mm heat-strengthened glass on both sides, with an anti-reflective front coating.
- Black-frame finish: 30 mm black anodised aluminium alloy frame for visible roof installations.
- Long-term warranty cover: 15-year product warranty and 30-year power guarantee, with 1% first-year degradation and 0.4% annual power attenuation stated by the manufacturer.
Where to use
The Trina Vertex S+ 515W dual glass solar panel is suitable for homes, offices, retail premises, workshops, warehouses, agricultural buildings and commercial rooftop solar PV systems. It is a practical option for projects that need high-output modules without moving to the largest utility-scale panel formats.
At 1,961 × 1,134 mm and 23.5 kg per panel, use a mounting system approved for the module frame, dimensions, clamping zones and local loading conditions. Confirm roof structure, string voltage, inverter DC limits and electrical protection requirements before installation.
Energian can help with module quantities, mounting selection, inverter and optimiser compatibility, battery integration and complete solar PV system design. Where a system cannot be used out of the box, installation can be arranged through trusted partners.
