Voltage check against the microinverter datasheets — confirm the pairing on the manufacturer’s module compatibility list. Rows appear only when the panel’s power is inside the microinverter’s recommended module power range.

SolarEdge and other optimizer-based systems size strings by the optimizer rules — use the manufacturer’s designer. Reference inverters: most named in SoCal permits since Oct 2024.

Questions & answers

How efficient is the JinkoSolar JKM325M-60HBL?

Calculated from the panel area (1.69 m²): about 19.3% for the 325 W class. 325 W over 1.69 m² equals about 193 W per square meter.

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

PVWatts v8 with typical-year weather gives about 545 kWh per year per 325 W panel in Los Angeles and about 596 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.36 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.6% 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 = 43.7 V, Vmp at 74 °C cell = 26.6 V). Final design must follow the inverter manual and NEC 690.7.

What does the warranty cover?

10 years on the product and 25 years on performance (manufacturer datasheet).

How big and heavy is it?

66.3 × 39.4 × 1.38 in (1,684 × 1,002 × 35 mm), 41.9 lb (19 kg).

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.

What fire rating does it have?

UL 61730 fire rating Type 1 per datasheet.
