Calculated from the panel area (2.58 m²): about 21.7% for the 560 W class. 560 W over 2.58 m² equals about 217 W per square meter.
PVWatts v8 with typical-year weather gives about 939 kWh per year per 560 W panel in Los Angeles and about 1,028 kWh in Palmdale (20° roof, facing south, 14% system losses).
With γ = −0.301 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.6% 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 2–11 panels per string (Voc at 2 °C = 53.5 V, Vmp at 74 °C cell = 34.8 V). Final design must follow the inverter manual and NEC 690.7.
Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 53.5 V vs max input 60 V; Vmp when hot 34.8 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.
Yes. Rear gain depends on mounting height and ground reflectance.
