Trina Vertex S+

The Vertex S+ is the other panel we fit most often. It is a dual-glass N-type i-TOPCon module: glass on both faces instead of a polymer backsheet, which gives it a better fire rating and much better resistance to moisture ingress and harsh weather over a 25-year life on a British roof.

N-type TOPCon cells degrade more slowly than the older P-type PERC panels most UK systems were built with, so a Vertex S+ array is still producing closer to its rated output well into its second decade.
