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 JOLYWOOD (TAIZHOU) SOLAR TECHNOLOGY JW-HD96N-R2 445?

Calculated from the panel area (2 m²): about 22.2% for the 445 W class. 445 W over 2 m² equals about 222 W per square meter.

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

PVWatts v8 with typical-year weather gives about 746 kWh per year per 445 W panel in Los Angeles and about 817 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.292 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.1% 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 3–16 panels per string (Voc at 2 °C = 37.4 V, Vmp at 74 °C cell = 24.9 V). Final design must follow the inverter manual and NEC 690.7.

Is it bifacial?

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

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; JOLYWOOD (TAIZHOU) SOLAR TECHNOLOGY was named a Top Performer in 5 Scorecards (2021–2026).
