Questions & answers

How efficient is the LG Electronics LG360A1K-V5?

Calculated from the panel area (1.67 m²): about 21.6% for the 360 W class. 360 W over 1.67 m² equals about 216 W per square meter.

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

PVWatts v8 with typical-year weather gives about 603 kWh per year per 360 W panel in Los Angeles and about 661 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.306 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.9% below the STC rating.

What microinverter is built into the LG Electronics LG360A1K-V5?

The CEC listing names LM320UE-A2 paired with the LG360Q1K-V5 DC module; the microinverter is rated 322 W AC.

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).
