Defaults come from NLR TMY weather (coldest hour, hottest modeled cell). Code calculations (NEC 690.7) use the ASHRAE extreme annual minimum, which is usually colder — enter it above. β is the CEC-measured coefficient; NEC 690.7 calculations use the datasheet value.

Microinverters (one per panel)

No microinverter in the reference set lists this power class in its recommended module power range.

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 Phono Solar PS585M8GFH-24/TNHB?

Calculated from the panel area (2.56 m²): about 22.9% for the 585 W class. 585 W over 2.56 m² equals about 229 W per square meter.

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

PVWatts v8 with typical-year weather gives about 980 kWh per year per 585 W panel in Los Angeles and about 1,073 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.293 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.2% 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 2–10 panels per string (Voc at 2 °C = 55.6 V, Vmp at 74 °C cell = 37.2 V). Final design must follow the inverter manual and NEC 690.7.

Has this panel been reliability-tested?

PSxxxM8GFH-24/TNH was a PVEL Top Performer in 2024, 2025 (LID+LETID, PID) — a closely related product name.
