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.

Same fields from the same sources for every row; ≈ efficiency is calculated from the listed area. Comparable series: other brands, same product group, power range covering this class.
How efficient is the Trina Solar TSM-430NE09RH.05?
Calculated from the panel area (1.98 m²): about 21.7% for the 430 W class. 430 W over 1.98 m² equals about 217 W per square meter.
How much energy does one panel produce in Los Angeles or Palmdale?
PVWatts v8 with typical-year weather gives about 721 kWh per year per 430 W panel in Los Angeles and about 789 kWh in Palmdale (20° roof, facing south, 14% system losses).
How much power does it lose on a hot roof?
With γ = −0.310 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 16.1% 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 3–16 panels per string (Voc at 2 °C = 36.2 V, Vmp at 74 °C cell = 23.9 V). Final design must follow the inverter manual and NEC 690.7.
Has this panel been reliability-tested?
TSM-xxxNE09RH.05 was a PVEL Top Performer in 2026 (HSS, LID+LETID, MSS, PID, TC).
