IQ8+ simulation results
The following tables shows the simulated single-module values for dierent DC:AC ratios on the IQ8+ Microinverter in
locations covering across the United States, using a -0.35%/C simple eciency model. The IQ8+ Microinverter has a peak
output power rating of 300 VA. In this model, the module orientation is xed at 180° azimuth, 20° tilt. Many real-world PV
systems do not have ideal true south orientations of 180° azimuth and ideal tilt angles, so the impact of clipping will be less
than shown in the tables below.
