Changing all the bulbs to LED's and supplementing your heat with something like this would reduce your power consumption. Maybe, to a point where existing charging options could keep up.
I have used one of these in my trailer. It does cut down the furnace run time.
+1 on the Buddy heater. Early spring camping in northern MI often involves subfreezing night time temps, causing the furnace in my popup to run the single GR31 battery down well before morning arrives, so I use a Big Buddy hooked to a 20 lb bottle as a supplement, and we stay toasty all night.
