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-435NEG9RH.25?

Calculated from the panel area (1.98 m²): about 22% for the 435 W class. 435 W over 1.98 m² equals about 220 W per square meter.

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

PVWatts v8 with typical-year weather gives about 729 kWh per year per 435 W panel in Los Angeles and about 798 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.291 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.1% 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 = 37.4 V, Vmp at 74 °C cell = 24.5 V). Final design must follow the inverter manual and NEC 690.7.

Has this panel been reliability-tested?

TSM-xxxNEG9RH.25 was a PVEL Top Performer in 2026 (LID+LETID).
