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.

Questions & answers

How efficient is the Bila Solar AA530US-6x24GG?

Calculated from the panel area (2.51 m²): about 21.1% for the 530 W class. 530 W over 2.51 m² equals about 211 W per square meter.

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

PVWatts v8 with typical-year weather gives about 888 kWh per year per 530 W panel in Los Angeles and about 973 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.333 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.2% 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 2–11 panels per string (Voc at 2 °C = 52.2 V, Vmp at 74 °C cell = 33.9 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with APsystems (Alt Power System) DS3-L microinverters?

Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 52.2 V vs max input 60 V; Vmp when hot 33.9 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

Is it bifacial?

Yes. Rear gain depends on mounting height and ground reflectance.

Has this panel been reliability-tested?

AAxxxUS-6x24GG was a PVEL Top Performer in 2026 (DH, LID+LETID, MSS, PID, TC).
