The Qcells datasheet guarantees at least 20.9% module efficiency for the 410 W class (up to 21.1% for 415 W). 410 W over 1.96 m² equals about 209 W per square meter.
PVWatts v8 with typical-year weather gives about 687 kWh per year per 410 W panel in Los Angeles and about 752 kWh in Palmdale (20° roof, facing south, 14% system losses).
With γ = −0.34 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.6% below the STC rating.
With the Tesla 1538000-xx-y (max DC 600 V, MPPT from 60 V, datasheet) in Los Angeles the calculator gives 2–12 panels per string (Voc at 2 °C = 48.2 V, Vmp at 74 °C cell = 30.6 V). Final design must follow the inverter manual and NEC 690.7.
Voltage check against the Enphase datasheet: Voc when cold 48.2 V vs max input 60 V; Vmp when hot 30.6 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.
25 years on the product and 25 years linear on performance: at least 86% after 25 years (manufacturer datasheet).
