Unless you are going to invest in a major solar farm, Solar will not work. Those here using solar ( few hundred watt) to recharge batteries during the day have battery banks ( 2-4 batteries) and are running minimal appliances. This is very different than full time living and using a CPAP. If you have a propane fridge, you can run it an WH with minimal drain, but you have issues with the microwave, and will not be able to run the AC. If the 5er is on the lot where the house is being built, I would suggest having a power run early in the construction and adding a temp box for 5er.
