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 URE (United Renewable Energy) FBM445M7G-BB?

The URE (United Renewable Energy) datasheet guarantees at least 20.6% module efficiency for the 445 W class (up to 21% for 455 W). 445 W over 2.16 m² equals about 206 W per square meter.

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

PVWatts v8 with typical-year weather gives about 746 kWh per year per 445 W panel in Los Angeles and about 817 kWh in Palmdale (20° roof, facing south, 14% system losses).

How much power does it lose on a hot roof?

With γ = −0.33 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 17.1% 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 3–13 panels per string (Voc at 2 °C = 44.5 V, Vmp at 74 °C cell = 28.4 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 44.5 V vs max input 60 V; Vmp when hot 28.4 V vs MPPT low 28 V; recommended module power 265–570 W. Confirm on the microinverter maker’s compatibility list.

What does the warranty cover?

25 years on the product and 25 years on performance: at least 84.8% after 25 years (manufacturer datasheet).

How big and heavy is it?

75.1 × 44.6 × 1.38 in (1,908 × 1,134 × 35 mm), 53.4 lb (24.2 kg).

Who installs it in Southern California?

Building permits name this series 3 times (Jun 2024 – Mar 2025). The most active licensed installers are T & T Construction Services.
