Questions & answers

How efficient is the JinkoSolar JKM455M-7RL3-V?

The JinkoSolar datasheet guarantees at least 20.5% module efficiency for the 455 W class (up to 21.2% for 470 W). 455 W over 2.25 m² equals about 203 W per square meter.

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

PVWatts v8 with typical-year weather gives about 763 kWh per year per 455 W panel in Los Angeles and about 835 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.35 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.1% 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 2–10 panels per string (Voc at 2 °C = 54.9 V, Vmp at 74 °C cell = 34.6 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 54.9 V vs max input 60 V; Vmp when hot 34.6 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 performance (manufacturer datasheet).

How big and heavy is it?

85.9 × 40.5 × 1.57 in (2,182 × 1,029 × 40 mm), 57.5 lb (26.1 kg).

Has this panel been reliability-tested?

JKMxxxM-7RL3-V was a PVEL Top Performer in 2021, 2022, 2023 (DH, LID+LETID, MSS, PID, TC).
