Read the article on Dry Camping suggested by Tree Seeker. It was fairly good but the price of solar has really dropped since 2005-2006 when that article was published".
Fortunately, my wife likes the cabin fairly cool and we let it get down into the 40's at night. We only leave the forced air heater on if it gets into the teens (and then it was long past time to head south) so that the tanks/valves don't freeze. Always turn off the water and open the valves at night when it gets below freezing so the pipes don't freeze.
We have plenty of battery to run the forced air heater (9.6 kW-hr), it just wastes to much propane.
