Technology & Performance Notes
Mono PERC is a workhorse mainstream technology with excellent bankability and low $/W. At 20.9% module efficiency the Q CELLS Q.PEAK DUO L-G8.3 445 converts 20.9% of incident solar irradiance into DC electricity, putting it in the mainstream efficiency tier for its class. The 196.0 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Q CELLS Q.PEAK DUO L-G8.3 445 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 (11 A) with the standard 1.25x safety factor.
