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 Waaree BiH-1 380?

Calculated from the panel area (2.03 m²): about 18.7% for the 380 W class. 380 W over 2.03 m² equals about 187 W per square meter.

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

PVWatts v8 with typical-year weather gives about 637 kWh per year per 380 W panel in Los Angeles and about 697 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.251 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 13% 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 2–10 panels per string (Voc at 2 °C = 56.1 V, Vmp at 74 °C cell = 38.8 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with Enphase IQ8PLUS-72-2-US microinverters?

Voltage check against the Enphase datasheet: Voc when cold 56.1 V vs max input 60 V; Vmp when hot 38.8 V vs MPPT low 29 V; recommended module power 235–440 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?

This exact series is not in published PVEL Top Performer tables; Waaree was named a Top Performer in 5 Scorecards (2022–2026). RETC named Waaree Overall Highest Achiever in 2025, 2026.
