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.

PVEL Top Performer (manufacturer)2 Scorecards (2024–2025)
How efficient is the Jiangsu Runergy New Energy Technology HY-DH108N8T 420?
Calculated from the panel area (1.95 m²): about 21.5% for the 420 W class. 420 W over 1.95 m² equals about 215 W per square meter.
How much energy does one panel produce in Los Angeles or Palmdale?
PVWatts v8 with typical-year weather gives about 704 kWh per year per 420 W panel in Los Angeles and about 771 kWh in Palmdale (20° roof, facing south, 14% system losses).
How much power does it lose on a hot roof?
With γ = −0.304 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 15.7% 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 3–14 panels per string (Voc at 2 °C = 40.1 V, Vmp at 74 °C cell = 26.3 V). Final design must follow the inverter manual and NEC 690.7.
Has this panel been reliability-tested?
HY-DH108N8-xxx was a PVEL Top Performer in 2024 (DH, LID+LETID, TC) — a closely related product name.
