Microinverters (one per panel)

No microinverter in the reference set lists this power class in its recommended module power range.
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.

Questions & answers

How efficient is the Trina Solar TSM-585NEG19RC.20?

Calculated from the panel area (2.68 m²): about 21.8% for the 585 W class. 585 W over 2.68 m² equals about 218 W per square meter.

How much energy does one panel produce in Los Angeles or Palmdale?

PVWatts v8 with typical-year weather gives about 980 kWh per year per 585 W panel in Los Angeles and about 1,073 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.316 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 16.4% 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 2–11 panels per string (Voc at 2 °C = 50.2 V, Vmp at 74 °C cell = 32.6 V). Final design must follow the inverter manual and NEC 690.7.

Is it bifacial?

Yes. Rear gain depends on mounting height and ground reflectance.

Has this panel been reliability-tested?

TSM-xxxNEG19RC.20 was a PVEL Top Performer in 2023, 2024, 2026 (DH, HSS, LID+LETID, MSS, PAN, PID, TC).
