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.

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 Shanghai Aerospace Automobile Electromechanical HT60-156M(V)-C 330?

Calculated from the panel area (1.82 m²): about 18.1% for the 330 W class. 330 W over 1.82 m² equals about 181 W per square meter.

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

PVWatts v8 with typical-year weather gives about 553 kWh per year per 330 W panel in Los Angeles and about 606 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.365 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.9% 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 = 43 V, Vmp at 74 °C cell = 27.2 V). Final design must follow the inverter manual and NEC 690.7.

Has this panel been reliability-tested?

HT60-156M-xxx was a PVEL Top Performer in 2022 (DH, LID+LETID) — a closely related product name.
