Questions & answers

How efficient is the Meyer Burger Meyer Burger Black 385?

Calculated from the panel area (1.84 m²): about 20.9% for the 385 W class. 385 W over 1.84 m² equals about 209 W per square meter.

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

PVWatts v8 with typical-year weather gives about 645 kWh per year per 385 W panel in Los Angeles and about 706 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.26 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 13.4% 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 2–12 panels per string (Voc at 2 °C = 47 V, Vmp at 74 °C cell = 32.9 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 47 V vs max input 60 V; Vmp when hot 32.9 V vs MPPT low 29 V; recommended module power 235–440 W. Confirm on the microinverter maker’s compatibility list.

How big and heavy is it?

69.6 × 41 × 1.38 in (1,767 × 1,041 × 35 mm), 43.4 lb (19.7 kg).

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; Meyer Burger was named a Top Performer in 1 Scorecard (2024).
