Technology & Performance Notes
TOPCon is the leading n-type technology for high efficiency with strong low-light and temperature behaviour. At 22.3% module efficiency the Trina Vertex N TSM-570NEG21C.20 converts 22.3% of incident solar irradiance into DC electricity, putting it in the premium efficiency tier for its class. The 220.9 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Trina Vertex N TSM-570NEG21C.20 into a string:
- Keep the string Voc (temperature-corrected to the coldest expected cell temperature) below the inverter’s maximum DC input voltage.
- Keep the string operating Vmp within the inverter’s MPPT window across the expected temperature range.
- Size fusing and conductors against Isc (14 A) with the standard 1.25x safety factor.
