Calculated from the panel area (2.01 m²): about 19.4% for the 390 W class. 390 W over 2.01 m² equals about 194 W per square meter.
PVWatts v8 with typical-year weather gives about 654 kWh per year per 390 W panel in Los Angeles and about 716 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 2–11 panels per string (Voc at 2 °C = 51.9 V, Vmp at 74 °C cell = 31.9 V). Final design must follow the inverter manual and NEC 690.7.
Voltage check against the Enphase datasheet: Voc when cold 51.9 V vs max input 60 V; Vmp when hot 31.9 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.
25 years on the product and 25 years linear on performance: at least 83.1% after 25 years (manufacturer datasheet).
This exact series is not in published PVEL Top Performer tables; JinkoSolar was named a Top Performer in 12 Scorecards (2014–2026). RETC named JinkoSolar Overall Highest Achiever in 2023, 2025, 2026.
