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.
Integrated roof products are wired per the manufacturer’s system design.
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 CertainTeed Apollo Tile II - 72?

Calculated from the panel area (0.54 m²): about 13.3% for the 72 W class. 72 W over 0.54 m² equals about 133 W per square meter.

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

PVWatts v8 with typical-year weather gives about 121 kWh per year per 72 W panel in Los Angeles and about 132 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.371 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.2% below the STC rating.
