Questions & answers

How efficient is the JinkoSolar JKM515M-7TL4-TV?

Calculated from the panel area (2.46 m²): about 20.9% for the 515 W class. 515 W over 2.46 m² equals about 209 W per square meter.

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

PVWatts v8 with typical-year weather gives about 863 kWh per year per 515 W panel in Los Angeles and about 945 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.423 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 21.9% 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 2–11 panels per string (Voc at 2 °C = 52.8 V, Vmp at 74 °C cell = 31.1 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 52.8 V vs max input 60 V; Vmp when hot 31.1 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

Is it bifacial?

Yes. Rear gain depends on mounting height and ground reflectance.

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.
