I am living in a off grid solar home. I have enough power during the day to run a small window unit but can't. Keep humidity levels down. Any ideas how to keep levels down without. Using a/c

I am wanting to build a off grid home in Northeast Arkansas, considering using sand bags filled with 100% sand as wall infill of a Pole Barn building with metal roof and using a combination or wood, rock and maybe cordwood on different exterior walls. My main question is could I insulate with rigid insulation and if so would it need to go on the interior on exterior.
