Questions & answers

How efficient is the EGing PV EG-545M72-HL/BF-DG?

Calculated from the panel area (2.57 m²): about 21.2% for the 545 W class. 545 W over 2.57 m² equals about 212 W per square meter.

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

PVWatts v8 with typical-year weather gives about 913 kWh per year per 545 W panel in Los Angeles and about 1,000 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.335 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.4% 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 = 52.9 V, Vmp at 74 °C cell = 34.2 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with APsystems (Alt Power System) DS3-L microinverters?

Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 52.9 V vs max input 60 V; Vmp when hot 34.2 V vs MPPT low 28 V; recommended module power 265–570 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?

EG-xxxM72-HL/BF-DG was a PVEL Top Performer in 2023 (DH, LID+LETID, MSS, PAN, PID, TC).
