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 ZNShine Solar ZXM7-SHLDD108-405/M?

The ZNShine Solar datasheet guarantees at least 20.7% module efficiency for the 405 W class (up to 21.2% for 415 W). 405 W over 1.94 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 679 kWh per year per 405 W panel in Los Angeles and about 743 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.35 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.1% 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 = 39.8 V, Vmp at 74 °C cell = 25 V). Final design must follow the inverter manual and NEC 690.7.

Is it bifacial?

Yes, bifaciality 70 ± 5%. Rear gain depends on mounting height and ground reflectance.

Has this panel been reliability-tested?

ZXM7-SHLDD108-xxx/M was a PVEL Top Performer in 2022, 2023 (DH, LID+LETID, PID, TC).
