Questions & answers

How efficient is the Jiangsu Green Energy Power Technology GEO-NM10-60TS 470?

Calculated from the panel area (1.9 m²): about 24.7% for the 470 W class. 470 W over 1.9 m² equals about 247 W per square meter.

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

PVWatts v8 with typical-year weather gives about 788 kWh per year per 470 W panel in Los Angeles and about 862 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.378 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.6% 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 3–13 panels per string (Voc at 2 °C = 45.1 V, Vmp at 74 °C cell = 29 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 45.1 V vs max input 60 V; Vmp when hot 29 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.
