Calculated from the panel area (2.48 m²): about 21.6% for the 535 W class. 535 W over 2.48 m² equals about 216 W per square meter.
PVWatts v8 with typical-year weather gives about 897 kWh per year per 535 W panel in Los Angeles and about 982 kWh in Palmdale (20° roof, facing south, 14% system losses).
With γ = −0.374 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.4% 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 = 52.9 V, Vmp at 74 °C cell = 33.1 V). Final design must follow the inverter manual and NEC 690.7.
Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 52.9 V vs max input 60 V; Vmp when hot 33.1 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.
