Questions & answers

How efficient is the LG Electronics LG360N1C-N5?

The LG Electronics datasheet guarantees at least 20.8% module efficiency for the 360 W class. 360 W over 1.73 m² equals about 208 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 = −0.34 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.6% 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 = 44.1 V, Vmp at 74 °C cell = 28.7 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 44.1 V vs max input 60 V; Vmp when hot 28.7 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

What does the warranty cover?

25 years on the product and 25 years on performance: at least 98% of rated power in year 1, then no more than 0.33% per year — at least 90.1% after 25 years (manufacturer datasheet).

How big and heavy is it?

66.9 × 40 × 1.57 in (1,700 × 1,016 × 40 mm), 39.7 lb (18 kg).

Has this panel been reliability-tested?

LGxxxN1C-N5 was a PVEL Top Performer in 2021 (DH, LID+LETID, MSS, PID).
