Questions & answers

How efficient is the Bluesun BSM460M-72HBD?

Calculated from the panel area (2.17 m²): about 21.2% for the 460 W class. 460 W over 2.17 m² equals about 212 W per square meter.

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

PVWatts v8 with typical-year weather gives about 771 kWh per year per 460 W panel in Los Angeles and about 844 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.377 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.5% 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 2–11 panels per string (Voc at 2 °C = 54.3 V, Vmp at 74 °C cell = 33 V). Final design must follow the inverter manual and NEC 690.7.

Does it work with APsystems (Alt Power System) DS3-L microinverters?

Voltage check against the APsystems (Alt Power System) datasheet: Voc when cold 54.3 V vs max input 60 V; Vmp when hot 33 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

How big and heavy is it?

82.4 × 40.9 × 1.18 in (2,094 × 1,038 × 30 mm), 61.7 lb (28 kg).

Is it bifacial?

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