Questions & answers

How efficient is the Risen Energy RSM144-7-440BMDG?

Calculated from the panel area (2.23 m²): about 19.7% for the 440 W class. 440 W over 2.23 m² equals about 197 W per square meter.

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

PVWatts v8 with typical-year weather gives about 737 kWh per year per 440 W panel in Los Angeles and about 807 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.337 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.5% 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 = 52.5 V, Vmp at 74 °C cell = 33.6 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 52.5 V vs max input 60 V; Vmp when hot 33.6 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?

RSM144-7-xxxBMDG was a PVEL Top Performer in 2022 (DH, LID+LETID, PAN, PID, TC).
