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 AXITEC AC-360MH/120VB?

The AXITEC datasheet guarantees at least 19.8% module efficiency for the 360 W class (up to 20.3% for 370 W). 360 W over 1.82 m² equals about 198 W per square meter.

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

PVWatts v8 with typical-year weather gives about 603 kWh per year per 360 W panel in Los Angeles and about 661 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 3–13 panels per string (Voc at 2 °C = 43 V, Vmp at 74 °C cell = 27.4 V). Final design must follow the inverter manual and NEC 690.7.

What does the warranty cover?

25 years on the product and 25 years on performance: at least 85% after 25 years (manufacturer datasheet).

How big and heavy is it?

69.1 × 40.9 × 1.38 in (1,755 × 1,038 × 35 mm), 43 lb (19.5 kg).

What fire rating does it have?

UL 61730 fire rating Type 1 per datasheet.
