Questions & answers

How efficient is the LG Electronics LG410N2W-L5?

Calculated from the panel area (2.07 m²): about 19.8% for the 410 W class. 410 W over 2.07 m² equals about 198 W per square meter.

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

PVWatts v8 with typical-year weather gives about 687 kWh per year per 410 W panel in Los Angeles and about 752 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.342 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.7% 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 = 52.4 V, Vmp at 74 °C cell = 34 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 52.4 V vs max input 60 V; Vmp when hot 34 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; LG Electronics was named a Top Performer in 2 Scorecards (2018–2021).
