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 PT IDN SOLAR TECH NUSA120H-360MB?

Calculated from the panel area (1.82 m²): about 19.8% for the 360 W class. 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 = −0.375 %/°C, at a 77 °C cell temperature (hottest modeled hour in Palmdale) output is about 19.4% 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 3–13 panels per string (Voc at 2 °C = 44.2 V, Vmp at 74 °C cell = 26.6 V). Final design must follow the inverter manual and NEC 690.7.

Has this panel been reliability-tested?

This exact series is not in published PVEL Top Performer tables; PT IDN SOLAR TECH was named a Top Performer in 1 Scorecard (2024).
