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 Bluesun BSM415M10-54HPH?

The Bluesun datasheet guarantees at least 21.2% module efficiency for the 415 W class. 415 W over 1.95 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 696 kWh per year per 415 W panel in Los Angeles and about 762 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.35 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 18.1% 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 3–14 panels per string (Voc at 2 °C = 40.2 V, Vmp at 74 °C cell = 25.5 V). Final design must follow the inverter manual and NEC 690.7.

How big and heavy is it?

67.8 × 44.6 × 1.18 in (1,722 × 1,134 × 30 mm), 47.4 lb (21.5 kg).
