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.

Microinverter tables are not shown for panels under 200 W.

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 Merlin Solar Technologies RFP-F036B175L?

Calculated from the panel area (1.09 m²): about 16.1% for the 175 W class. 175 W over 1.09 m² equals about 161 W per square meter.

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

PVWatts v8 with typical-year weather gives about 293 kWh per year per 175 W panel in Los Angeles and about 321 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.331 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.1% below the STC rating.
