Enter the latitude and longitude of the PV installation in the boxes provided, or use the
Lookup City button to substitute the latitude and longitude of a city near your PV
installation.
The Site Info screen has a special feature for horizontal single-axis tracking systems,
which allows the I-V curves to be taken while the tracker is working. This has the
advantage of taking all of your measurements at the greatest possible irradiance level.
The user enters the morning azimuth of the array, and at solar noon the software adds 180
degrees for the afternoon azimuth.
Figure 33 shows example settings for a fixed (non-tracking) array.

In this example, the PV modules are facing East in the morning hours (before solar
