I would think you really would need a back up energy plan. December, January, February, November and March. Limited sun for solar Means lots and lots,of big battery’s for storage. Temps in winter can be below zero for weeks at a time means lots of big battery’s for storage. First thing to consider is making the place as energy efficient as possible. R60 insulation is attic with Foam or cellulose is a start. Foam insulation in all walls, or cellulose.
band joists sealed properly and insulated. Windows....windows suck for energy efficiency Cause glass is a poor insulator. Even the latest, greatest triple,glass with argon gas inside still suck. But try to make sure they are prop installed and seal well.. doors should seal well. Metal doors tend to transmit the cold from outside to inside. Wood or fiberglass not so much. LED lighting. High efficiency appliances.
Landscaping/trees. A heavily treed lot may block lots of sun which is free heat. Trees to the south may block winters sun when there’s actual winter sun up there. To little trees or open exposure could open you up to high winds that
wick away the heat.
id have to consider some kind of back up plan or some possible power assist. Solar and propane. Solar and electric. Solar and nat. Gas (best)
Question for the OP. Is the OP married? Kids? Grandkids? I know many, many people who move to their retirement homes and one year later, hate it.
women especially. To far away from friends. To far away from kids. To far away from grandkids. Brutal winter conditions. Looked in the small home for hours and days on end. Gosh, I know so many people who just don’t like it. My sister being one. She did like six months up north and that was enough. Had to come home and only goes up for two weeks at a time and this was in summer, not winter.
my mother in law hated, absolutely hated retirement in Gaylord. Winter was unbearable for her.
just some things to consider
