Calculated from the panel area (2.16 m²): about 20.6% for the 445 W class. 445 W over 2.16 m² equals about 206 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 = −0.373 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.3% below the STC rating.
Yes. Rear gain depends on mounting height and ground reflectance.
HT60-18X-xxx was a PVEL Top Performer in 2022, 2023, 2024, 2025 (DH, HSS, LID+LETID, MSS, PAN, PID, TC).
