Where to point your panels?

I've been moving my portable array mount around and lost calibration.
So, I was trying to find the local Solar Noon (to find true south) and,
found this neat app on the web..

You can drag the map around, until the cursor is on your location.

With your tracker, doesn't that eliminate the need for this?

Only if I had installed an elevation motor and tracker..

I still need to point the mount at the apex (true South) at solar noon.

I could tell it was off a little, by looking at the shadow stick late in the afternoon.
If there is up or down shadow, the mount is not aligned to true south.
