The JinkoSolar datasheet guarantees at least 20.7% module efficiency for the 460 W class (up to 21.2% for 470 W). 460 W over 2.25 m² equals about 205 W per square meter.
PVWatts v8 with typical-year weather gives about 771 kWh per year per 460 W panel in Los Angeles and about 844 kWh in Palmdale (20° roof, facing south, 14% system losses).
With γ = −0.35 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.1% 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 2–10 panels per string (Voc at 2 °C = 55 V, Vmp at 74 °C cell = 34.7 V). Final design must follow the inverter manual and NEC 690.7.
Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 55 V vs max input 60 V; Vmp when hot 34.7 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.
