Shelly Ann, I would stop adjusting the panels because it sounds like a lot of work (unless you're really bored and actually enjoy it0.
Your best bet is to set the panels east west lengthwise and angle the panels to face the southern sky.
Before 11:00 am and after 5:00 pm, the sun is relatively low on the horizon to make much of a difference on heat gain, you want as much gain as possible between the hours of 11 and 5, since the sun is pretty much over top in the southern sky, facing south will give you the best gain.
Besides, all teh propping would induce unnecessary strain on the panels reducing their life span I would think
