The Trina Solar Vertex S+ TSM-515NEG18R.28 is a high-performance dual-glass, N-type i-TOPCon PV module designed for commercial & industrial rooftops and universal rooftop systems. Its compact format (length below 2 meters) helps reduce BOS costs and improves handling on site, while the dual-glass construction boosts reliability in harsh environments and high humidity/temperature areas.
High output in a compact format: 515 W STC with high efficiency for strong yield on limited roof area.
N-type i-TOPCon performance: improved long-term energy harvest with low degradation profile.
Dual-glass reliability: excellent fire resistance and durability for demanding climates.
High mechanical strength: tested to 5,400 Pa snow load and 2,400 Pa wind load.
Long warranties: 25-year product workmanship warranty and 30-year power warranty with 1% first-year degradation and 0.4% annual from year 2–30.
