Defaults come from NLR TMY weather (coldest hour, hottest modeled cell). Code calculations (NEC 690.7) use the ASHRAE extreme annual minimum, which is usually colder — enter it above. β is the CEC-measured coefficient; NEC 690.7 calculations use the datasheet value.

Questions & answers

How efficient is the JinkoSolar JKM345M-6TL3-B?

Calculated from the panel area (1.68 m²): about 20.5% for the 345 W class. 345 W over 1.68 m² equals about 205 W per square meter.

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

PVWatts v8 with typical-year weather gives about 578 kWh per year per 345 W panel in Los Angeles and about 633 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.375 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.4% 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 3–14 panels per string (Voc at 2 °C = 42.8 V, Vmp at 74 °C cell = 26.2 V). Final design must follow the inverter manual and NEC 690.7.

Has this panel been reliability-tested?

JKMxxxM-6TL3-B was a PVEL Top Performer in 2022 (LID+LETID, MSS, PID, TC).
