Calculated from the panel area (2.2 m²): about 20.2% for the 445 W class. 445 W over 2.2 m² equals about 202 W per square meter.
PVWatts v8 with typical-year weather gives about 746 kWh per year per 445 W panel in Los Angeles and about 817 kWh in Palmdale (20° roof, facing south, 14% system losses).
With γ = −0.33 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.1% 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 2–11 panels per string (Voc at 2 °C = 52.4 V, Vmp at 74 °C cell = 34 V). Final design must follow the inverter manual and NEC 690.7.
Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 52.4 V vs max input 60 V; Vmp when hot 34 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.
25 years on the product and 25 years on performance: at least 98.5% of rated power in year 1, then no more than 0.33% per year — at least 90.6% after 25 years (manufacturer datasheet).
