Suntech Power STP415-54/Nshd (415 W)
The Suntech Power STP415-54/Nshd is a 415 W solar module built on Mono PERC technology (Monocrystalline PERC (Passivated Emitter Rear Cell)). It delivers a maximum-power voltage (Vmp) of 31.6 V at a maximum-power current (Imp) of 13.13 A, with an open-circuit voltage (Voc) of 37.5 V and a short-circuit current (Isc) of 13.8 A under Standard Test Conditions (1000 W/m², 25 °C, AM1.5G). Conversion efficiency is 21.2% across a 1722 x 1134 mm footprint.

Technology & Performance Notes
Mono PERC is a workhorse mainstream technology with excellent bankability and low $/W. At 21.2% module efficiency the Suntech Power STP415-54/Nshd converts 21.2% of incident solar irradiance into DC electricity, putting it in the mainstream efficiency tier for its class. The 212.8 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Suntech Power STP415-54/Nshd 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 (13.8 A) with the standard 1.25x safety factor.
