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 PEIMAR DR10H460M?

Calculated from the panel area (2.25 m²): about 21.5% for the 460 W class. 460 W over 2.25 m² equals about 204 W per square meter.

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

PVWatts v8 with typical-year weather gives about 771 kWh per year per 460 W panel in Los Angeles and about 844 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.355 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.4% 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 = 44.4 V, Vmp at 74 °C cell = 27.3 V). Final design must follow the inverter manual and NEC 690.7.
