Solar Frontier SF170-S (170 W)
The Solar Frontier SF170-S is a 170 W solar module built on Thin-Film CIGS technology (Copper Indium Gallium Selenide (CIGS) thin-film). It delivers a maximum-power voltage (Vmp) of 15.4 V at a maximum-power current (Imp) of 11.04 A, with an open-circuit voltage (Voc) of 20.4 V and a short-circuit current (Isc) of 12 A under Standard Test Conditions (1000 W/m², 25 °C, AM1.5G). Conversion efficiency is 13.9% across a 1257 x 977 mm footprint.

Technology & Performance Notes
Thin-Film CIGS is a flexible thin-film technology used for lightweight and building-integrated applications. At 13.9% module efficiency the Solar Frontier SF170-S converts 13.9% of incident solar irradiance into DC electricity, putting it in the value efficiency tier for its class. The 138.2 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Solar Frontier SF170-S 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 (12 A) with the standard 1.25x safety factor.
