Trina Solar Vertex S+ TSM-415NEG9.28 415W N-Type Bifacial

Trina's Vertex S+ combines bifacial N-Type TOPCon cells with a glass-backsheet design optimized for ground-mount, carport, and flat-roof ballast systems. Bifacial gain of 10–25% depending on ground albedo pushes real-world energy yield well above the 415W STC nameplate. N-Type advantages over P-Type: no LETID, lower soiling losses, superior diffuse-light sensitivity. 415Wp front STC, 21.9% module efficiency, Voc 38.7V, bifaciality factor ≥70%, 25-year linear warranty at 0.4%/yr degradation. ⚠️ Certification note: IEC 61215 / IEC 61730 and CE certified. MCS listed. NOT ETL or UL listed.
