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.

Same fields from the same sources for every row; ≈ efficiency is calculated from the listed area. Comparable series: other brands, same product group, power range covering this class.
How efficient is the Aptos Solar DNA-108-MF10-410W-USAptos2?
The Aptos Solar datasheet guarantees at least 21% module efficiency for the 410 W class. 410 W over 1.95 m² equals about 210 W per square meter.
How much energy does one panel produce in Los Angeles or Palmdale?
PVWatts v8 with typical-year weather gives about 687 kWh per year per 410 W panel in Los Angeles and about 752 kWh in Palmdale (20° roof, facing south, 14% system losses).
How much power does it lose on a hot roof?
With γ = −0.33 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.1% 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 3–15 panels per string (Voc at 2 °C = 40 V, Vmp at 74 °C cell = 25.7 V). Final design must follow the inverter manual and NEC 690.7.
