Questions & answers

How efficient is the LG Electronics LG365M1C-N5?

Calculated from the panel area (1.73 m²): about 21.1% for the 365 W class. 365 W over 1.73 m² equals about 211 W per square meter.

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

PVWatts v8 with typical-year weather gives about 612 kWh per year per 365 W panel in Los Angeles and about 670 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.34 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.6% below the STC rating.

What does the warranty cover?

25 years on the product: at least 98% of rated power in year 1, then no more than 0.33% per year — at least 90.08% after 25 years (manufacturer datasheet).

How big and heavy is it?

66.9 × 40 × 1.57 in (1,700 × 1,016 × 40 mm), 43 lb (19.5 kg).

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).

What fire rating does it have?

UL 61730 fire rating Type 1 per datasheet.
