Questions & answers

How efficient is the ELITE Solar ET-M672BH400GL?

Calculated from the panel area (2.04 m²): about 19.6% for the 400 W class. 400 W over 2.04 m² equals about 196 W per square meter.

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

PVWatts v8 with typical-year weather gives about 670 kWh per year per 400 W panel in Los Angeles and about 734 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.376 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.5% 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 = 53.1 V, Vmp at 74 °C cell = 32.8 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 53.1 V vs max input 60 V; Vmp when hot 32.8 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.

Is it bifacial?

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

Has this panel been reliability-tested?

ET-M672BHxxxGL was a PVEL Top Performer in 2022 (DH, MSS, PID, TC).
