Well it's not quite the end of the day and there is still a little 
usable light, but I've disconnected the panel and brought it in for the 
night.  The final reading isn't what I expected.  11.9V.  I went out 
about 6PM and it was at 12.1V, so there was some increase in stored 
energy.  I solved the puzzle in short order though.  The battery that 
I'm charging is connected to my camper.  My 7 year old was out there 
watching a DVD with a friend, using the portable DVD player, but it 
seems they felt that they needed one of the interior lights on. 
Additionally, my yard is heavily shaded by trees.  I think I'll try this 
again later in the week and disconnect the battery from the camper and 
position everything where it can receive direct sunlight without any 
leaves blocking it.  All in all though I think it was a good purchase 
and with some wind generated capacity and a few more deep cycle 
batteries, I should soon be able to take my shack off grid completely.
