First Solar Series 6 Plus FS-6460 (460 W)
The First Solar Series 6 Plus FS-6460 is a 460 W solar module built on Thin-Film CdTe technology (Cadmium Telluride (CdTe) thin-film). It delivers a maximum-power voltage (Vmp) of 69 V at a maximum-power current (Imp) of 6.67 A, with an open-circuit voltage (Voc) of 81.2 V and a short-circuit current (Isc) of 7.02 A under Standard Test Conditions (1000 W/m², 25 °C, AM1.5G). Conversion efficiency is 18.5% across a 2009 x 1232 mm footprint.

Technology & Performance Notes
Thin-Film CdTe is a thin-film technology prized for hot-climate performance and low manufacturing energy. At 18.5% module efficiency the First Solar Series 6 Plus FS-6460 converts 18.5% of incident solar irradiance into DC electricity, putting it in the value efficiency tier for its class. The 185.5 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the First Solar Series 6 Plus FS-6460 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 (7.02 A) with the standard 1.25x safety factor.
