Defaults come from NLR TMY weather (coldest hour, hottest modeled cell). Code calculations (NEC 690.7) use the ASHRAE extreme annual minimum, which is usually colder — enter it above. β is the CEC-measured coefficient; NEC 690.7 calculations use the datasheet value.

Voltage check against the microinverter datasheets — confirm the pairing on the manufacturer’s module compatibility list. Rows appear only when the panel’s power is inside the microinverter’s recommended module power range.
SolarEdge and other optimizer-based systems size strings by the optimizer rules — use the manufacturer’s designer. Reference inverters: most named in SoCal permits since Oct 2024.

How efficient is the Trina Solar TSM-360DE06X.05(II)?
Calculated from the panel area (1.82 m²): about 19.8% for the 360 W class. 360 W over 1.82 m² equals about 198 W per square meter.
How much energy does one panel produce in Los Angeles or Palmdale?
PVWatts v8 with typical-year weather gives about 603 kWh per year per 360 W panel in Los Angeles and about 661 kWh in Palmdale (20° roof, facing south, 14% system losses).
How much power does it lose on a hot roof?
With γ = −0.339 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.6% below the STC rating.
How many panels fit on one string?
With the Tesla 1538000-xx-y (max DC 600 V, MPPT from 60 V, datasheet) in Los Angeles the calculator gives 2–12 panels per string (Voc at 2 °C = 47.5 V, Vmp at 74 °C cell = 30.2 V). Final design must follow the inverter manual and NEC 690.7.
Does it work with Enphase IQ8PLUS-72-2-US microinverters?
Voltage check against the Enphase datasheet: Voc when cold 47.5 V vs max input 60 V; Vmp when hot 30.2 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.
Has this panel been reliability-tested?
TSM-xxxDE06X.05(II) was a PVEL Top Performer in 2022 (LID+LETID, MSS, PID, TC).
