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-SH108-405/M?
Calculated from the panel area (1.96 m²): about 20.7% for the 405 W class. 405 W over 1.96 m² equals about 207 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.
What does the warranty cover?
12 years on the product and 25 years on performance (manufacturer datasheet).
Has this panel been reliability-tested?
This exact series is not in published PVEL Top Performer tables; ZNShine Solar was named a Top Performer in 8 Scorecards (2016–2026).
Who installs it in Southern California?
Building permits name this series 9 times (Jan 2023 – Aug 2025). The most active licensed installers are American Array Solar Electric.
