About This Product

VERTEX S+ TSM-515NEG18R.28 NON TRACEABLE is a Trina Solar module from the Vertex S+ family, using n-type i-TOPCon cells in a dual-glass black frame format. This exact model is rated at 515W, uses a 108 half-cell layout, and is aimed at higher-output rooftop jobs where string efficiency and long-term durability matter. It sits in Trina Solar’s mid-size commercial and industrial range, with a lower voltage design that can help keep string design practical on larger roofs.

Who This Product Suits

This panel suits commercial rooftops, sheds, workshops, farm buildings and larger residential installs where fewer, higher-wattage modules are preferred. It is a sensible option for installers wanting a current-generation Trina Solar panel with n-type cell technology, dual glass construction and a 25-year product warranty. It is best suited where roof space is valuable and you want to get more wattage per panel without stepping into oversized utility-style modules.
