Questions & answers

How efficient is the JinkoSolar JKM365M-66H-V?

Calculated from the panel area (1.77 m²): about 20.6% for the 365 W class. 365 W over 1.77 m² equals about 206 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 = −0.376 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.5% 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 3–12 panels per string (Voc at 2 °C = 46.6 V, Vmp at 74 °C cell = 29.6 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with Enphase IQ8PLUS-72-2-US microinverters?

Voltage check against the Enphase datasheet: Voc when cold 46.6 V vs max input 60 V; Vmp when hot 29.6 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; JinkoSolar was named a Top Performer in 12 Scorecards (2014–2026). RETC named JinkoSolar Overall Highest Achiever in 2023, 2025, 2026.
