Questions & answers

How efficient is the Seraphim SRP-545-BMA-BG?

Calculated from the panel area (2.56 m²): about 21.3% for the 545 W class. 545 W over 2.56 m² equals about 213 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 = −0.331 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.1% 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 2–11 panels per string (Voc at 2 °C = 52.9 V, Vmp at 74 °C cell = 34 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 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?

SRP-xxx-BMA-BG was a PVEL Top Performer in 2021, 2022 (DH, LID+LETID, MSS, PAN, PID, TC).
