Hi Westend,
I'd get a plastic dart with a suction cup end. At one hour before solar noon I'd stick it on the panel and adjust for the least amount of shadow.
An hour before noon the sun would be 15 degrees east of south and the sun would be lower by some angle. It is not clear what you mean by 'adjust'
The usual advice is to pick some angle lower than for noon if using a south facing panel (if it twirls during the day facing the sun, then its tilt at noon is the lowest angle for the day, so you would be raising the tilt either side of noon instead)
Optimum is given here:

but put in context here, where PV watts is used. It seems optimum tilt is lower when cloudy and higher at high elevation (of interest to JiminDenver)
