So I just spent 4 days in Moab with friends. We had a little rain, some crazy high winds and sun. I camped in my usual spot which faces my camper pretty much due East. My battery voltage never drooped below 12.9 volts. It seems that the voltage for these (2, 6 volt Trojan AGM's) is fully charged around 13.0+ volts. I ran the fantastic fan a few times, my new led strip lighting (45 watts) and the furnace one night. My wife did not go on this trip and I did not use as much power as I usually when camping in colder weather, but I have not doubt that this system is going to preform, even when not pointed south. Only issue I had is the adhesive failed on one of the cable tie brackets.
