Trina Solar Vertex S+ 475W

The Trina Solar Vertex S+ TSM-475NEG9RH.28 is a 475W n-type dual glass monofacial solar module purpose-built for residential and light commercial rooftop installations. Utilising Trina's patented i-TOPCon Ultra cell technology, it delivers a module efficiency of up to 23.7% through continuous improvements in contact resistance reduction, rear reflection enhancement, and edge quality refinement. Its compact dimensions of 1762mm x 1134mm and lightweight 21kg design make it easy to handle and install, while remaining compatible with mainstream inverters and a wide variety of mounting systems.

The dual glass construction with heat-strengthened 1.6mm front and back glass offers excellent durability, reducing the risk of micro-cracks and back-side scratches that can affect long-term performance. With a low temperature coefficient of -0.29%/°C and validated excellent low irradiance performance, the Vertex S+ maintains strong output during hot Australian summers and overcast conditions alike. The panel is also rated to withstand front static loads of up to 5400 Pa and rear loads of up to 4000 Pa, ensuring resilience in demanding weather environments.

Trina Solar backs the TSM-475NEG9RH.28 with a 25-year product warranty and a 30-year linear power performance warranty, with just 1% first-year degradation and 0.4% annually thereafter — guaranteeing at least 87.4% output at the end of year 30. With its proven i-TOPCon technology, robust dual glass build, and industry-leading warranty terms, the Vertex S+ 475W is a reliable, high-efficiency choice for homeowners seeking long-term energy performance and peace of mind.
